Guo Kai didn't come back from the Imperial College until the sun sets, and went to Lantai to sing Mao. After proving that he was alive, Guo Kai didn't have to go to Lantai anymore, so he took a few days off.

When taking leave, Guo Kai was not embarrassed at all. He had always worked flexibly with Jian Yong. He might have something to do at any time, and sometimes he would have three days and three nights of liver. After he finished his liver, he would ask for leave on his behalf and slept for a day and a night of sleep.

Therefore, Guo Kai didn't think there was any problem with taking leave, and even felt that it was quite rare for him to take the initiative to take the leave. In the past, others asked for leave for him.

On the contrary, the other censors had a complicated expression and had not been appointed for almost two years. They asked for leave on the first day of their appointment, mainly because Guo Kai came with a leave note given by Li You.

If the Lantai Censors were not under Li You, they knew who Li You were, and they would have doubted whether this kid was Li You's illegitimate son.

After receiving the leave note, Guo Kai went to Taixue to see his teacher with a gift. After that, he was taken as an excellent model student as an exhibition and gave two Go classes instead of Wang Lie, which opened the eyes of the students, and they all had such expressions.

Later, Guo Kai showed the way to play the endgame with God. The juniors were stunned, especially those juniors who had been classmates with Guo Kai were all irritated, and even their jealousy for Guo Kai's bronze seal and black ribbon. Is this a person doing things?

Although Guo Kai simply described what this job was done and calculated it in math. The students who were good at math could figure it out even more, when the local map was put on and started to seriously demonstrate how to play an endgame with God, the juniors felt that this was really something they should understand at this age?

After just demonstrating this, it was getting dark. Then Guo Kai wore his cloak and chatted with a few old classmates for a while, saying that after Xiu Mu invited everyone to dinner, he quickly left. To be honest, Guo Kai was not used to this kind of attention-catching environment.

Although he had a good time when he was in Taixue before, he had a good skill, but that kind of thing was just a high-profile among his classmates. But now, to be honest, he can't stand it anymore.

Therefore, after making a talk with a few classmates, Guo Kai quickly slipped away.

It was already dark when Guo Kai walked back. Although the neighbors here had special street lights, since the changes in the sky, the activity of the essence of heaven and earth has increased, resulting in a lot of decrease in the brightness of the street lights. Li Yuan, who was in charge of this matter, should have quickly begun to study new etching technology, but for some reasons, the light has been so dim.

In Li Yuan's words, this luminance is only suitable for the oil lamp level, and this luminance is only suitable at night. The type before was too bright. In short, the street lamp boards installed in the Han Dynasty are almost at this level in terms of brightness.

"Shengzhi, is there anything wrong?" Just as Guo Kai was about to go home, the door of Langalajan's house opened, and then Langalajan poked out half of his body and asked, obviously he was waiting for Guo Kai to come back, and the half-open main door was enough to allow Guo Kai to see that Lan Bozu's house was brightly lit.

"It's nothing, but I need to pay a visit to my mother and grandfather." Guo Kai thought for a while and said, not understanding why Langarajan was waiting for him.

"You've finished paying homage. If you have nothing to do, you can come to my place. I have a Go enthusiast here." Langarajan said with a smile, and Guo Kai nodded to express his understanding.

Guo Kai walked back, Langalajan did not close his door, and quickly returned to his own hall. He insisted on letting Masinde see how small human Go is.

"Have you been attracted?" Masinde asked with a grin.

"Wait, it'll be here in a while." Langalajan said with a little sarcasm. He is really not as good as Ma Xinde if he doesn't use his spiritual talent, but it's useless. If he uses his spiritual talent, Ma Xinde is definitely not an opponent. Then what is the result when Guo Kai comes, it goes without saying.

"There are really many strange things in the Han Dynasty." Masinde looked at the light panel hanging on the top of Langarajan's living room and shook his head, "I think there are such things outside in the open air."

"Chen Zichuan said that disasters are likely to happen at night. It is because the night is quiet and light, so it is easy to install street lights, whether it is to make updates or patrolers. In addition, there is generally no curfew in Chang'an. At night, many people do some needlework under the street lights and chat." Langalajan explained casually, "Later, Chen Zichuan set up a large workshop to produce this."

"This thing is not easy to produce." Masinde took a look and confirmed that there were traces of etching on it. He knew that this thing was not possible for ordinary people. Maybe the headlights in Langarajan's living room were all developed by Langarajan's research on the etching of street lights at the door.

"It's not easy to produce, so someone here has created automatic printing and etching equipment to let the buyer activate it himself." Langarajan said expressionlessly.

Masinde was stunned. Can the automatic rubbing and etching equipment be activated by itself?

"It's the wife of Zhuge Kongming, the terrifying young man." Langarajan said calmly, "This is also the reason why the street lights at the door are difficult to replace. It is not that we cannot create the lamp boards above our heads that consume the essence of heaven and earth to produce light energy. There is a high probability that we cannot produce the new automatic printing and etching equipment, so we can only do this first."

"I think it's OK outside, but it's much brighter than oil lamps." Masinde glanced at the street lights outside the exterior wall and said with a little emotion.

"Compare this on your head and say it again." Langarajan sneered. "It is different from being able to popularize a technology and being able to use it at our level."

"It used to be so bright?" Masinde said in surprise.

"In the past, Chang'an was brightly lit, and it was like daytime at night. I have seen the Chang'an scene recorded by wealthy families in Chang'an. At that time, the Shangyuan Festival was the city that never sleeps." Langarajan said with great emotion. "Now many people are studying this light board, hoping to restore the never sleep of Chang'an again. Unfortunately, the new automatic printing and etching equipment has never been created."

There is no automatic rubbing and etching equipment, and manual alone, the labor cost is too high under the premise that most ordinary people can't perform etching.

It is true that as long as a giant like Masinde masters this etching, you can take some time to make a big piece of it for your own use, but how many giant like Masinde have?

The reason why Li Yuan was favored back then was actually designed to design the Yuanrong crossbow to automatically fill and etch the etching technology when filling the crossbow arrows, as well as the lamp plate rubbing and etching technology based on this. Both of them are the low-end popularization foundations of high-end technology.

As a result, the Tianbian broke out both of them, causing the difficulty of rubbing and etching technology to increase wildly, resulting in Li Yuan, who could have done it before, still unable to do it in this environment after studying it for a long time.

How to say this technology? In Chen Xi's opinion, it can almost be regarded as the basis for the development of the world's essence and energy technology. All technologies can only develop rapidly by solving the problem of technology popularization. Only a few people can use things, even if they can be continuously promoted, their efficiency will be extremely low.

Unfortunately, Li Yuan is a little discouraged because of this thing. After more than two years of work, there is almost no progress. If he hadn't known that the technical ideas were correct, Li Yuan might have changed directions.

"Even people like me who don't understand business can see this thing, it's worthless." Ma Xinde looked at it and said.

"Yes, the value is uncountable, that is, because of the uncountable value, the five major merchants in the Central Plains have special investments. However, as of now, only at my level, no one can develop automatic printing and etching technology. They can only be manually used. Even if they rely on manpower and can be diluted, the cost of those who can do this is very high." Langarajan nodded and said.

Chen Xi actually asked the Shaofu to do it privately, although he was also working on the technology of turning the essence of heaven and earth into electricity and then lighting up the lights with electricity, especially the latter, the technical ideas are very clear. If you really want to do it, Chen Xi can almost do it now.

However, Chen Xi is now on an awkward branch line. Li Yuan’s technology has a clear direction, and the time to pile up will definitely be accumulated. The cost of Li Yuan’s technology branch is lower than the cost of Chen Xi’s electric light route. Moreover, Li Yuan’s technology branch is likely to be one of the basic foundations of Tiandi Jingqi Technology.

So Chen Xi kept stuck here and looked at the situation first. If there was no movement for ten or eight years and it was stuck and could not move at the moment, then take the light route first.

This is also the reason why Chen Xi was very accommodating and even somewhat willing to do so to the Chang'an lamp board incident.

"All of this is true, they are all smart people. Unfortunately, some things don't do that at all." Ma Xinde said with a faint mockery. He saw the benefits, but some benefits are not something you can get just by wanting, so it's helpless.

"Speaking of this, my biggest feeling in Chang'an is that the thinking mode of the Han Dynasty is different from that in ours." Langarajan said with some thoughts. The two of them now need to deepen their understanding of each other and also need to share the same position with each other.

"It has nothing to do with Chang'an, it has a lot to do with Chen Zichuan. His position is on development. When I met me today, I had already explained some things with me. The angle is very different, but it is indeed beyond my previous cognition and is very clear in structure." Ma Xinde said very seriously, "His understanding of the world is a completely systematic logic."

"Who isn't there at this level?" Langalajan asked inexplicably.

If you don’t communicate directly with Chen Xi, even if you only look at the various construction and developments in the Central Plains, it is actually just a blind man touching an elephant. Just like before Ma Xinde met Chen Xi, he had a huge change in the evaluation of roads, construction, transportation, etc. before he met Chen Xi.

The previous reviews were not wrong, but were completely covered by the later cognition. What I really want to say before was actually "I don't know the true face of Mount Lu, but I just have to be in this mountain."

Langarajan has a high level, but Langarajan has not systematically communicated with Chen Xi about social structure and national operations. When Chen Xi faced Masinde, he realized that Masinde is the most important puzzle for the current national operation and social construction, so he decisively gave the lowest-level framework construction structure.

The easiest way to recognize reality in this world is to stand at the bottom of the mountain and look up and stand at the top of the mountain to look down. Chen Xi gave the lowest framework construction structure, which is enough for people of Masinde to see too many things clearly.

"It's true that there are, but his understanding of the world can be completely compatible with you when it's completely compatible with me. What he said before, "The main thing is that you are too weak. If you are strong enough to suppress everyone, it's not a problem." In fact, it's correct. He suppressed everyone and may also be compatible with all their cognitions."

Langarajan stopped smiling and just looked at Masinde.

"If it weren't for this, would I agree so easily? There is a saying in the Han Dynasty that Tao is different and we don't make plans for each other." Masinde sighed, and Langarajan became extremely solemn.

Masinde didn't care, and told Langarajan the structure he heard from Chen Xi about the bottom of society. After listening, Langarajan fell into deep thought, and even Guo Kai didn't react when he came in through the main entrance.

"What's wrong with Lan Bozu?" Guo Kai looked at Ma Xinde in confusion and asked.

"Thinking about problems." Ma Xinde said casually, "Are you Brother Chen's grandson? You are very handsome, especially with this kind of demeanor, young talent, tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk

Guo Kai scratched his head and was a little reluctant to respond. As a result, Masind pulled Guo Kai to take his seat. As for Guo Kai's name Rangala Janran Bozu, Masind didn't ask him to change it. Just like others called him Lao Ma, they no longer cared about this.

However, unlike Langalajan who saw Guo Kai, when Masinde's eyes fell on Guo Kai, even if he did not open up his spiritual talent, he could vaguely feel the suitable direction for Guo Kai. Such people have always been the most worthy of training in Masinde.

Therefore, this young talent is not a simple praise, but a true manifestation of Mashinde's belief that this child is suitable for work.

"Ma Bozu." Guo Kai went down, but Ma Xinde was definitely bigger than Chen Bozu in his early sixties, so Guo Kai called Ma Bozu very respectfully. Ma Xinde responded and took Guo Kai directly to the inner hall, leaving the stunned Langalajan in place.

The next day, Ma Xinde was stinky. Yesterday, he was killed by Guo Kai, so he was numb. He dreamed of playing chess at night, but he didn't recover even when he woke up.

Langarajan thought about the real night after Masinde recounted Chen Xi’s underlying operational structure and the people completed their full production.

Langarajan is different from Masinde. He is a descendant of the Daxia royal family. The destruction of Daxia by the Great Yuezhi was considered usurpation, so his descendants still enjoy privileges. As a noble, he was hit even more.
