The Yong family has a bit of a bad idea, and it is indeed a bad idea in terms of behavior. However, since the survival place requires a lot of etching technology to maintain, the technical output is actually not very large every year.

After all, Zhou Yu and others are studying related etching technologies to beat people, while the Yong family is currently studying etching technologies purely for living. After that, they can survive in various situations. The motivation for their research on etching will become proactive development. After all, this place is in winter for half of the year, and if they don’t do anything, they are prone to bipolar disorder.

Of course, the people of the Central Plains who are currently living here do not feel bipolar disorder at all, but seem very peaceful. After all, they first came out from a place where there seemed to be no good means of survival besides rebellion. The survival pressure here is extremely low, and the mentality is extremely peaceful in the short term.

After a few years of adapting to the survival pressure here, bipolar disorder will gradually appear. After all, when survival is difficult, this disease that obviously affects life will take people away before it really breaks out. Only in a time of peace and happiness, can people with this mental illness and self-care ability be reduced to survive.

Social welfare and social development have led to the gradual normalization of certain diseases. It is not before, but simpler. Before this disease was detected, people had already died for various reasons, and most people could not survive the time when the cause of the disease was found.

Only a peaceful and happy era can give most people the strength to curse the country alive. If they are exhausted to live, they will probably be insensitive to anything, but neither before nor after.

In short, no matter what, the etching of the Yong family's thermal insulation and temperature change type is definitely the world's number one. Zhou Yu thought that it was the first time he saw something that could definitely solve any problem. If he really threw it on the Yong family's wall, it would probably be a bit overload of the original heat dissipation and refrigeration. It would be a dream to break the wall or something.

However, for the things that the Yong family can easily withstand, for Kushan, who has not thought about how to face such things, it is a decisive victory.

Even Kou Jun had to think about how to deal with the walls in Tanjavur and other places when he saw the cracked city walls, but this idea only existed in Kou Jun's mind for a moment and gave up.

At least the city wall they are currently using is absolutely unable to resist this high-intensity heat and heat change. The thermal expansion and contraction caused by high temperature and low temperature are enough to make the city wall crack directly.

[Looking back, the city wall must be renovated. Zhou Gongjin, no wonder no one can resist it for the first time. So that's the case?] Kou Jun glanced at Zhou Yu, then looked at the city wall that began to explode, and was ready to lead people to charge at any time.

Zhou Yu looked cautious, because the next moment was the most difficult moment. Kushan would definitely use naval guns. After all, when the inner city was broken, whether to use naval guns and whether the city wall would collapse after use was no longer so important.

From a realistic perspective, it is almost inevitable to use naval guns as the final strike at this time. Even if it is a close-range blast, causing a certain section of the inner city to collapse, it will have no effect. After all, the city wall itself has collapsed, which is very suitable as the final strike.

Although Zhou Yu is not sure what agreement Kou Jun and others have reached with Kus Luo Yin, from Kus Luo Yin's position, as long as he doesn't want Kusshan to be finished so soon, it is almost inevitable that the other party will take ruthless measures.

Therefore, when the inner city wall began to collapse, Zhou Yu was ready. All kinds of siege equipment were placed in appropriate positions when they were pushed over before. These things were transported to resist the last blow.

After all, as early as when the Kushan air rail cannon came out, the Han Dynasty received news that an air rail cannon was used as a fortress cannon on the inner wall of Qunun City.

Although it is a test work, it is not the main gun with the greatest power, as the most powerful weapon of this era, its power also has an absolute suppressive effect on the army.

At least for now, there is no conventional army with the ability to fight against such strikes. Whether it is the military soul or the three talents, it is very likely to be directly destroyed when facing such strikes without preparation. Miracles can withstand, but how many miracles are there?

Therefore, when Zhou Yu was preparing to fight the girl city, he was ready to resist this thing. There were few people in this world who knew the power of naval guns better than Zhou Yu, and there were also few people who were more confident to resist this thing than Zhou Yu.

To be honest, when Kushan repaired the air rail cannon and placed it on the inner city, he only used it as a deterrent. After all, the reaction force brought by the air rail cannon is not small, and it has a great impact on the inner city walls, but it is indeed excellent as a deterrent.

It was not until the Han army led Dalit to surround Qunu City that Kushan realized a reality that the air rail cannons set up on the inner city walls could not attack the opponents at close range in the outer city, because whether it was electromagnetic guns or air rail cannons, they were basically flat fires.

The result is that the air rail cannon in the inner city is completely impossible to attack the Han army in the outer city. A simple metaphor is two wooden boards with the same height. One of them is placed on one. Now you have to use this fastener to hit the things in front of the other wooden board. It can be done when it is far enough, but if the other party is very close to the city wall, it is actually impossible to hit it at all.

This is also why the air rail cannon quickly counterattacked after discovering Zhou Yu's naval army and directly exploded the flagship of the Han army, but it never attacked the Han army's army. It was not that they didn't want to attack the Han army's army, but that they really couldn't do it.

In fact, if you really have to stand on the Kushan design and layout, there is no problem with the air rail cannon in the inner city. If you really have to put it on the outer city wall, there is no problem in suppressing the army such as Kou Jun. However, Zhou Yu must have shot the air rail cannon in the first launch, the second launch broke the outer city, the third launch broke the inner city, and the fourth launch entered the palace. Then he positioned Liu's team and directly covered the naval cannon.

Zhou Yu could definitely do this. As for how to explain the fact that Liu Feng had lost his bones, of course he would use his title to win over and run away.

If it really doesn't work, I will still refuse to admit it. I insist that if I don't have a princess, it will be a rumor that Liu Cheng died of illness last year. Can you still come up with other evidence?

Relatively speaking, although there are many shortcomings in the inner city, at least such outrageous situations will not occur.

It was even too much. When it was really irreversible, the senior Kushan executives would really use naval guns to attack the enemy in the inner city. At that time, the people in the outer city were cannon fodder.

Zhou Yu vaguely developed this idea since he saw the design of Qunnu City, so he was ready to carry a naval gun when he came. All the siege equipment was sent by transport ships, which could explain many problems. The etching on these siege equipment was to reduce the subsequent possible blows. Of course, it would definitely not be reduced, but it would be enough to reduce to a certain extent.

The reason why I brought the Jiangdong Navy here this time is that only the Jiangdong Navy will not experience legionic collapse when facing this kind of strike.

For the Army, this kind of strike is too tragic, but for the navy, who is already used to the heavy ships, this level is completely within the acceptable range.

"Preparation of air rail cannons!" When Kusluo Yin exploded, it was just like Zhou Yu estimated. There was nothing to say at this point. What was used for it. Using air rail cannons at close range would inevitably lead to the collapse of the city wall, but it also had to be used for Kusluo Yin.

"Yes!" At this time, Kshatriya, who was controlling the air rail cannon, didn't care about the trivial matter of Kus Luo Yin being Dalit. He quickly controlled the air rail cannon to face the cracked position of the city wall. It took less than half a minute to complete the filling. After all, since the ship was hit, it has been in the open state. Now it has only completed preparations and is ready to strike.

"Die!" Kshatriya, who was controlling the air rail cannon, roaring and attacking the direction of the Han army. The mental image that Kusroyin had never used in front of others interfered with the Kshatriya, and the mental image was distant fantasy.

The mental image of slightly controlling the distance had an amazing effect at this moment. It deviated by 0.5 mm from the aiming port of the naval gun. When it was fired, it was directly deviated by nearly a hundred meters, directly avoiding the core of the Han army. Zhou Yu's various siege equipment also used the heaven and earth essence core to forcibly activate it at this moment, forming a layer of group deflection and deflection of the air-rail strike again.

It is impossible to withstand it. Even the flagships are difficult to withstand this kind of main gun-level strike. Even if the air rail cannon in the inner city of Qunun City is just a test piece, not the final version, its power is very amazing. At least the army present can't withstand it directly.

But being unable to withstand does not mean being unable to defend. As long as you are not hit, it is success. It is also based on this idea that Zhou Yu has developed the deflection defensive style of the group. This time, the effect of the deflection defensive style of the group was shocked by Zhou Yu.

Because the energy cannon fired by the air rail cannon was directly deflected into the outer city by this strike, and then the strong wind turned back, Zhou Yu didn't care about this matter at all and directed Varina to attack the air rail cannon. Zhou Yu dared to come and take over the job, so he was ready to deal with the naval cannon.

No matter how strong the naval gun is, it still requires human operation. Now that the city wall is broken, it may take some time for other legions to climb the city wall. This time is enough for the air rail gun to fire another shot, but Varina is different. His mind has the ability to leap on the plane.

Combined with the elite talents created by Zhou Yu, it is enough to allow the elite soldiers under Varina to take a few steps in the sky. Although it is not as good as Zhang Ping, a guy who can walk through the air nine times and fly around, the combination of this mental image and talent is enough to fall around the air rail cannon before the air rail cannon fires the second shot and kill the Kushan soldiers.

After all, the positioning of this legion is to cut the back row in chaos. No second legion can fly over the opponent's head and directly cut the back row. Varina can do it, so Varina directly ended the chaos in the inner city wall with one move.

From the break, he rushed to the city wall with the elite troops, and then almost did not fight with the opponent. He quickly jumped over the head of the Kushan soldiers who were blocking and blocking, and rushed to the position of the air rail cannon. The time spent all the way was extremely short.

In addition, the first air rail cannon was more than a kilometer away, and Kshatriya, who used air rail cannon, was stunned. Kusro Yin was embarrassed by his own operational error. Although he was not going to let the Kushan operate air rail cannons and blow the main force of the Han army away, he never thought that the Han army was completely unharmed.

It's a big problem if it's really not hurt. After all, Kshatriya, who was sent to control the air rail cannon, was the elite of the Peacock Legion under Rahul's command back then. He was the kind of existence that could analyze all bow and arrow errors with one precise talent.

Even if the air rail cannon is difficult to control, the hit rate is at least reliable, and it is the top-level existence among the four empire archers.

It turned out to be one kilometer away, which was really outrageous.

"Hurry up, let's go again!" Bankim shouted loudly, no Brahmin elegance was gone, and who could still notice this at this time? Even if Bankim wanted to get Vesutva I back and wanted to kill Liu Cheng as soon as possible, this situation was completely beyond Bankim's estimate. Why did the outer city suddenly break down? Why did he attack and the inner city break down?

"It is filling, but it takes time. The filling of this heavy weapon cannot be done in a short time." The voice of Kshatriya, who controlled the air rail cannon, was even a little desperate. He had never made such a big mistake in his life.

"What happened to you before?" Prasan also came over and roared.

Although these people knew that the power of naval guns was very powerful, it was the first time they had seen it at such a close distance. Therefore, they regarded this thing as a magic weapon in the country and waited for another shot. However, the previous one was too biased. Is this thing so poor in accuracy?

The accuracy difference is inevitable, but it is really not a kilometer away from this distance. This is the result of the double-layer influence. Kus Luo Yin's mental image and distant fantasy ability are to use the mind to interfere with reality, resulting in distortions of distance. This distortion can be widened and narrowed.

Of course, it will consume a lot of money to do this directly, but only interfere with the sensory distance and cooperate with a little distortion of the real distance will have a huge impact.

This mind image is the spiritual change that Kusluo Yin has completely understood Dalit's situation and made up his mind. As a guy who has blessed the gods and Buddhas to practice to the limit, and has even achieved substantial detachment, Kusluo Yin has also created a mind image after his mind has been transformed.

But Kus Luo Yin basically doesn't use this thing. He tried his best. If he couldn't beat his opponent, he still couldn't beat him. What's more, in the current situation, he might not be willing to do his best to protect Kus Luo Yin. Kus Luo Yin is just a platform for showing.
