"Don't we notify the Shi family of Hanoi?" A young man in the Gan family didn't react and looked at Gan Yu and asked very formally.

"I have to visit this in person." Gan Yu said with a dark face. Why do you have such a fool in your family? You can actually ask such mental retardation questions. Unlike the Wang family in Lujiang, Chen family in Jiujiang, and Zhou family in Brazil, the Shi family and the Gan family are truly professional in astronomy among the Central Plains families.

The three families in Lujiang, Jiujiang and Brazil are most famous in this area for nearly a hundred years. The Gan family in Moling and Shi family in Hanoi are the real professional ones to do this. To put it too much, the Taishi, who is in charge of the Astronomy Calendar under Jiuqing, was the two families who were in charge of the Grand Historiography.

Except for some gods such as Sima Qian, Luo Xiahong, and Zhang Heng, who are completely cheating, the celestial calendar is basically all about these two families.

As for the three bigwigs in front, the Sima Cuo family represented by Sima Qian was destroyed, and all the family education was cheaper than the Yang family; the Luoyanghong family was also destroyed, and all the family education was in the hands of the Zhou family in Brazil. The Zhou family could do astronomical phenomena. If Luoyanghong's background was not in the background, he would probably not even be able to go on the road.

The only family that still exists is the descendant of Zhang Heng in Nanyang. Since Zhang Heng's cheating is bigger than the one before, the descendants really cannot inherit it. The Zhang family collectively switched to mechanics and the essence and energy of heaven and earth, astronomy and calendar, and could no longer be picked up.

However, there is no way to do this. Zhang Heng's level is completely equivalent to a predecessor of the Spring and Autumn Period and the Warring States Period. To be honest, there has never been a single family in the entire Central Plains who completely inherited all the inheritance of a predecessor, because they can't bear it.

Even the Xunqing straight line like the Xun family did not completely inherit everything Xunzi. Many of them were passed on to other people and became family studies of other families. After all, some people were too far beyond the times. Given the situation at that time, it was a bit delusional to bear the inheritance of the ancestors.

Naturally, the Zhang family was forced to give up part of Zhang Heng's inheritance and specialize in mechanics and the essence and energy of heaven and earth. As for astronomy and calendar, this can only be lost. Even if Zhang Heng left this part of the foundation, it could support the foundation of a family, but it could only be lost.

As for the Gan family and the Shi family, they are considered the authority of this era in astronomy and astrology. By the way, the earliest astronomical works in world history were created by these two families, one called "Astronomy" and the other called "Astronomy and Astronomy". The two families are responsible for studying astronomical phenomena and often create very unparalleled things.

For example, in order to observe the comet cycle, generations have been studying it, and in order to determine an undetermined astronomical phenomenon, it has been spent on several generations to stare at a position.

Such crazy practices are basically no one else for professional enthusiasts who are not rich or have a lot of free time.

However, the Shi family and Gan family have specialized in this kind of person. It can be said that before these two families finished playing with astronomy and astrology, the two families basically represented the highest level of the earth in the same era, and they were separated from each other. The earliest astronomy book in world history was not one book, but two books because these were two.

Because you come out, I come out too, you study and I also study. The progress of both sides is basically the same. Then the two families were defeated by typhoid fever. This led to the rise of Xichuan Astronomy represented by the Zhou family in Brazil, the Wang family in Lujiang and the Chen family in Jiujiang.

However, judging from the current situation, it is impossible for typhoid fever to destroy all these two families like in official history. Naturally, the two families still do their own astronomy as before.

For this reason, the Gan family can send individuals to inform the other three families to discuss matters, but the Shi family must be invited by the Gan family's direct descendants. Even if they are slightly ahead of the Shi family because of some research, the Gan family knows very well that the Shi family is at most unlucky and did not pay attention to this direction. Otherwise, the other party's foundation is probably just a job of burning money to verify.

Because of a verification, the Gan family in Moling gathered five families who truly studied astronomy in the Central Plains and entered the era of buying colorless crystals to build large astronomical telescopes to verify astronomical phenomena. Chen Xi was silently watching this group of people doing things, and even secretly giving them some support, but it was time to wait for these people to achieve results. God knows how many years it will take.

If you are not lucky, it is like a normal template. There has been no progress for a whole thousand and five hundred years. If you are lucky, you will directly explain the scope of explanation that humans can explain in three years. Who knows this kind of thing?

However, Chen Xi’s main focus was not on this aspect. The Three Kingdoms at the end of the Han Dynasty could be said to be classics and the most miserable era of the school was not entirely because of war. In fact, it is really because of typhoid fever. After all, the people are unlucky in the war. As long as a real wealthy family does not commit suicide, they are almost laughing at the storm. However, typhoid fever does not matter whether you are a wealthy family or an ordinary person.

So much so that some schools of thought were directly destroyed, the two universities before astrology were wiped out, and some theories that still existed before the Three Kingdoms were directly intermittent.

You should know that before Zhang Zhongjing solved the problem of typhoid fever, he was already a famous doctor. However, when typhoid fever broke out in the Central Plains, Zhang Zhongjing's own record was that their Zhang family died seven or eight, and those who died were almost wiped out.

Under this nearly extinction-level mortality rate, with the view of ancient China, various universities and even some ruling academic valuations poured a piece of it like harvesting wheat.

Now Chen Xi asked Hua Tuo to get rid of typhoid fever in advance. Although the population still fell out, overall, the major pre-Qin theories and schools did not fall down like cutting wheat because of their sharp decline in population and views, becoming the dust of history.

What's more, Chen Xi gave hundreds of opportunities to defeat the lower Confucianism. Nowadays, each school is like absorbing nutrients and has begun to grow wildly. Although there is still a lot of knowledge monopolized by major aristocratic families, if you want to learn, the lower class still has the opportunity to get in touch.

It’s just that basic knowledge is nothing. The higher the knowledge, the more talent you need. Even if Chen Xi is open to some things, it is not something that the lower class can learn. Some things are simply useless for the people, and they may even have the idea that they are completely useless to waste time.

Because some knowledge does not have real meaning to the people who aim to eat and wear well, even if Chen Xi is open, it is meaningless. On the contrary, some families who specialize in studying these things will have a great increase in interest.

In fact, just like mathematics, for most people, mathematics in elementary and junior high schools is enough. Even if they are taught advanced mathematics, probability theory, and topology, if they can choose not to study, most people will never learn it.

Therefore, Chen Xi found a headache that for the vast majority of people, they actually don’t care much about knowledge. Although they hope that their children can learn knowledge, once they find that the knowledge learned by their offspring cannot fill their stomachs, their interest will plummet, even if they will support their children to continue learning.

On the contrary, for the children of aristocratic families who don’t have to worry about food, clothing and supplies, they don’t care whether the knowledge they have learned can be used to fill their stomachs. For them, knowledge is knowledge, there is no useless knowledge, only knowledge that has no usefulness.

So much so that if Chen Xi opens higher things now, basically the people do not have the resources to support one person to study for so long, and the other will either form a scholarship or be cheaper for a family. Chen Xi has no choice but to study, and it is also a costly investment.

However, it is obvious that for the people today, even the wealthiest people in Taishan, who are on average, it is difficult to afford the so-called higher education. It is helpless and realistic.

When you put all your goals on filling your stomach, others have already placed them in a very distant place. In this way, even if there is no gap in qualifications between the two parties, the former needs to surpass the latter, and the effort required to increase exponentially.

Therefore, looking at the information on the popularization results of education collected in his hand, Chen Xi could only sigh. All he could do was to narrow the gap as much as possible. If the aristocratic family had not completely rotten, they were indeed terrible to say that they were fighting power.

[What we need to do next is to keep the proportion of the capital of the aristocratic family in this country down until it drops below half. I don’t know if I can do it in my lifetime, so I always feel it’s unrealistic.] Chen Xi silently burned out the results he inferred from the current situation. After reading some things, it’s better not to leave a foundation.

When Chen Xi was wondering whether he could do it, Guan Yu, who was by the Huai River in Yuzhou, had completed the reorganization of his own legion. The elite legion with a number of up to 30,000 people. The leading Guan Yu headquarters and Guan Yu's formation's swordsman have all been replaced with the most elite reserve legion.

After Guan Yu, whose legion talent had reached its peak, expanded his legion talent in the way recorded in Han Xin's military book, he directly formed a stronger legion talent with the reserve elites who were originally under his command.

Unlike Zhang Ren's way of combining legion talents into elite talents to form new effects, the arrogant Guan Yu directly used the legion talent that could not surpass elite talents in theory to reorganize elite talents, deepening the legion talent that he had already inspired to the limit!

All elites belonging to Guan Yu's formation, after their elite talents are directly blessed by Guan Yu's will, will receive varying degrees of blessings according to Guan Yu's own will and the soldiers' recognition of Guan Yu, and will have the effect of deepening the elite talents.

To put it simply, once the Second Master’s legion talent is activated, it will be directly merged with the elite talent, and it will no longer be revealed. While having the ability to deepen the legion’s quality, it will also have the effect of strengthening the elite talent.

In other words, if the top exclusive elites led by other generals have the basic strength to fight against the three talents and military souls, and even perform well enough to fight against the three talents legion and military soul legion, then Guan Yu's original formation can already truly fight against the three talents.

The strengthening of quality and deepening of elite talents, the combination of the two is a special effect, which is less than the three talents. But to be honest, Guan Yu's absolute will is equivalent to a half-ideal effect, and this level is no less than the three talents that do not add anything.

This change was also fed back to Guan Yu, making Guan Yu's aura more condensed and made Guan Yu take a big step towards the heart disaster.

Just as Guan Yu was about to integrate and train his legion again, the Xinying from Yecheng arrived immediately. Guan Yu jumped up and grabbed Xinying in his hand, and untied the letter from the eagle's claws. The eagle, as a raptor, shivered in his face and did not dare to make any moves.

Guan Yu threw the letter eagle away, then stood in the sky and opened the letter. His half-closed eyes suddenly opened, and a cold light flashed through his eyes and then landed. Soon, a dull dot drum sounded from Guan Yu camp in the north of the Huai River.

Before the two drums were over, all the military advisors, staff officers, generals and schoolmen in Guanyu Camp appeared in the tent, and everyone arrived on a run, and no one was late.

Even a slut like Guo Jia, after the drum sounded, came to the camp at the time of the second drum and sat down to wait for Guan Yu's order, although he had already guessed.

"The soldiers obeyed the orders, all drove the camp, crossed the river and crossed Jingchu, and walked on the ancient road where Zhou Gongjin transported supplies to Central and South China!" Guan Yu's expression was still cold, but everyone felt the surging fighting spirit of Guan Yu. He was nestled in the Central Plains, so how could he fight to expand the territory and expand the territory?

"Here!" All the generals and schools stood up and reported that no one asked what happened to Guan Yu. For the civil and military officials under Guan Yu's command, Guan Yu's orders did not require any unnecessary words, and they were executed.

As the generals and schoolmen left with their fists and began to pull out the camp and reorganize the army, Guo Jia, Xu Shu, Chen Chi and others also had the opportunity to ask.

"Chang Yunchang, the situation in Central and Southern China..." Although Guo Jia did not say those two words, the meaning was self-evident. This was also a bad thing that was tormented by Li You, Jia Xu and others. It is best not to speak up as a crow.

"Not good, the letter of request for help was not sent by the official, but since Zhang Su wrote it, it explained the situation. Moreover, let's see how to solve this." Guan Yu handed over the letter. After Guo Jia reached out to catch it, he opened it and looked at it, and his eyebrows couldn't help but tremble.

"Yuanzhi, please take a look." Guo Jia frowned and handed the letter to Xu Shu who was a little anxious. After reading it, Xu Shu's face became extremely ugly. He handed the letter to Chen Chi casually. In the end, the civil servant group in the entire camp turned into bitter melon.

"Tell me, what should I do with this legion with a range of sight strikes?" Guan Yu went straight to the point. With his current legion, he would not be afraid of any opponent in the attack range.

But facing this situation where you can't see your opponent at all, it's nonsense even if you have the ability to play, and Guan Yu is facing this nonsense situation now.

Xu Shu looked at Guo Jia who was pressing his temple aside, and found that the other party had no idea of ​​speaking. He looked around and looked at the others with a look of embarrassment. He couldn't help but say awkwardly, "General, we have never encountered such a completely unexpected situation before, and there is no good way to be anxious."

Guan Yu's cold and arrogant expression could hardly see any joy and anger, but others felt some pressure inexplicably.

"Are you beyond the visual distance?" Seeing that the atmosphere in the camp was a little solemn, Xu Shu couldn't help but want to divert his attention. At this moment, Guo Jia, who had not spoken before, finally spoke.

When Guan Yu heard Guo Jia's words, he immediately turned his attention to Guo Jia. The pressure on others could not help but lighten. Speaking of which, Guo Jia had been cooperating with Guan Yu for the longest time. Guan Yu also had some understanding of the other party's abilities and was a very important character.

"Actually, this kind of thing doesn't need to be seen." Guo Jia turned the cup in his hand and said slowly. Guan Yu raised his eyebrows when he heard this. Seeing the wine glass turning in Guo Jia's hand, he touched a water bag containing wine and threw it over.

"How can the other party's bow and arrow be shot, and we can shoot it over. Anyway, since the other party can shoot so far and its power is so great, that is, it will probably only take ten seconds from shooting out to hitting. This time cannot be enough for them to transfer." Guo Jia Gudu Gudu and gave the answer happily after drinking a glass of wine.

Unfortunately, Guan Yu didn't understand what Guo Jia meant, and others didn't know what Guo Jia was talking about. Xu Shu caught some things, but like Fa Zheng's condition at that time, he couldn't figure out what it was.

"It's actually very simple. We really can't see where the opponent is, but the landing point, angle and direction of their arrows allow us to calculate the position of the opponent. Of course, this kind of thing requires reference experience and is not very accurate, but in fact we don't need to be accurate either." Guo Jia said indifferently.

"First correct the heavy crossbow, let us determine what the rough angle and range of the heavy crossbow with the twisted wire is. After the opponent attacks, we will fight back. Although the crossbow is slow to wind, it takes more than ten seconds to dozens of seconds, for the army, the position of the large army has not changed much in ten seconds or dozens of seconds." Guo Jia said calmly with his hands spreading.

"This is a solution, but the hit rate of the crossbow machine is not high." Guan Yu frowned and sootheed a lot. Guo Jia's method was indeed not very good, but compared to when everyone else had no choice, this method was already good and could not be better.

"The hit rate is meaningless to us. In fact, what we want is more to not be harassed by the other party. Attacks of that level are indeed very harmful, but if we really want to kill three thousand people in one wave, it is a good idea to kill three thousand people. Even if we put a legion with dangerous dodge at the front, this kind of arrow rain, which is not known for its density, can shoot hundreds of people, it is a miracle." Guo Jia curled his lips disdainfully, and there is no invincible thing in this world.

This powerful arrow is indeed terrifying, but Zhang Su's letter of help also said that only two thousand arrows covered the entire front line, and there is a possibility of evading arrows of this density.

To be precise, it would be more than worth the effort to withstand such arrows with obvious damage even for the formed double-talented shield guards.

On the contrary, dodging arrows with high power but low density is the best way to go, but it is normal to say that all arrows with a range that exceeds the visual range will not be too high.

For Guo Jia, arrows are so powerful and rare, so it is better to pursue a wall at a time, and no one can dodge it. As long as it can kill people, the arrows are sparse, and for some special legions, they can dodge them directly.

Some legions that come with dangerous dodge and speeding reaction can dodge if your arrows are not dense enough. The former does not need to be seen, and dodges based on feelings, while the latter can basically dodge as long as they see it. Although this talent is relatively rare, it is not without it!

Faced with a legion with the talent of dangerous dodging, these large arrows that cover a whole front are dodged in two thousand shots, and may be too scattered, and the entire army may successfully dodge them.

Therefore, for Guo Jia, this level of over-visual strike is not about the significance of harm, but about the suppression of the target's morale. It is about strategy, not how many people can be killed. In this way, as long as you are prepared, Guo Jia doesn't feel that it is too dangerous.

"What you mean is that the other party uses this kind of long-range attack to attack the camp..." Guan Yu frowned, understanding what Guo Jia said. If you think about it this way, as long as the arrangement is well arranged, there is actually nothing to be afraid of in this ultra-range legion on the battlefield.

"Strike the camp, forget it, this way of use is too stupid. The significance of this legion is to save the ground, break the stalemate, and strategic suppression. It is very important for the timing of use. As for the attack camp, it just looks beautiful." Guo Jia shook his head and said, Xu Shu completely reacted at this time, looking at Guo Jia with respect.

"The other party used this legion to attack our camp. In fact, we can also use crossbow machines to attack the other party's camp. Even if we can't see the other party's camp, as long as our scout determines the location, we can use the projectile to shoot the heavy crossbow arrows over. As for the deviation, it is actually not important for the camp whether the deviation is large or not, because the camp is very large." Xu Shu explained in admiration.

"Yes, that's it. This kind of thing is not difficult for us. It's a great waste of some heavy crossbow arrows. Just adjust the range bit by bit. In the end, the fixed angle direction is basically the same. And for the elite legion, it may only be a few rounds, crossbow machines..." Guo Jia said disdainfully, "You shoot one round, I will reply you ten rounds, do you believe it?"

"So that's it!" Guan Yu completely reacted, "So, this legion is actually more of an impact on the decisive battle?"
Chapter completed!
