In December of the fourth year of Zhenguan, the fine snowflakes flying all over the sky and tiny raindrops shrouded the entire Chang'an City in a fog. The reconstruction of the weapon surveillance became more and more difficult, with mud everywhere, and it was difficult to even step down in some places.

In addition to the necessary house repairs, everyone else asked Ning Wen to rush to the Houshan test range. He had never been rectified. He had to face Li Shimin's inspection at the end of the month, and the bunkers and other things had to be dug up.

Ning Wen planned to dig a bunker similar to a command post, slightly away from the artillery position, and then build a section of the city wall at 150 feet, 200 feet, and 300 feet respectively according to the size of the city wall to serve as a shooting range.

The command post is Li Shimin's bunker, and then a trench was dug out on both sides of the artillery position, connecting the command post and the shooting range, as a channel for delivering messages on the day of the experiment.

Ning Wen remembered that when military training and targeting was conducted in later generations, they used banners to report targets. It was too late to do it now. Anyway, it was the first experiment and there was no experience.

In the projectile manufacturing workshop, a group of skilled craftsmen were studying the process of overturning several projectiles. There was no problem with solid projectiles. They were relatively uniform in weight and roundness. However, this hollow explosion warhead was not able to be produced yet. I also asked Master Zhou and knew the principle. However, the steel furnace had not started to be built yet, and the hollow warhead had no raw materials to cast, so I had to stop.

Ning Wen is in a very depressed mood recently. Huai Liang and Diao Gui are also busy with their own work. After Ning Wen settled down the test range, he felt a little excited, so he rode his horse back home. Yu'er and Erya took Xiaowen to his father-in-law's house. They couldn't come back for a while. Only Lao Guo and Sangou Dayong were left at home. At this moment, they were busy unblocking the ditch in the corner of the yard. The dead leaves falling in autumn blocked the drainage ditch. Ning Wen had no intention of looking at it, so he went straight to the house and lay on the corpse. It felt very tired.

While lying in the corpse, Sangouzi came to pass the message in a hurry. Li Zhi was here and was using tea in the hall.

Ning Wen cheered up and came to the main hall. It seemed that Li Zhi was very worried about Ning Wen, so he asked before Ning Wen could see him:

"Teacher, Zhinu hasn't had the chance to leave the palace these days, is it okay for the teacher?"

Li Zhi seemed to hear some rumors, his eyes flashed, and Ning Wen no longer hid it, so he told Li Zhi about the weapons surveillance and told Li Zhi that he had been harmed.

"Teacher Commander, why do some people want to harm the division commander? How important is weapon supervision? Why do those evil people burn the weapon supervision? Such evil deeds can be punished for the crime of treason and can kill the nine clans!"

Li Zhi looked resentful. This was the most serious thing that Ning Wen said from Li Zhi since he had communicated with him. Li Zhi always spoke gently, paying great attention to his tone, and had never said such bloody words.

"Zhinu, do you know you're jealous? Just like when you saw the pigeons your sister raised that day, how do you feel?"

Ning Wen took this opportunity to think that he should change his strategy and pin his hopes on the future Emperor Gaozong. Guo Enxiong once said that this is a contribution to support.

"Oh, Zhinu felt very uncomfortable that day, and wanted to take the pigeon for his own thoughts."

Li Zhi looked up at Ning Wen, and the child was thinking. Ning Wen smiled and signaled Li Zhi to sit down and talk.

"Zhinu, this is jealous. He is the chief of the army and the weapons supervisor. Many ministers also have the same thoughts as Zhinu. However, Zhinu asked for it from the army, and they just wanted to seize it for themselves."

Ning Wen felt very relaxed when talking to Li Zhi. He had seen so many princes, but he only opened his heart to Li Zhi. Maybe Ning Wen had known the direction of history, or maybe Li Zhi had given people this trustworthy feeling.

"Teacher Commander, everyone is an important minister of the court, and what he does is also for the sake of the Tang Dynasty. Why do some people be jealous of the Division Commander?"

Li Zhi felt it was incredible, and it was not as good as what he learned since childhood. The books all said that people are like ministers, and they are all first-class loyal and patriotic people. Why do some people want this? Li Zhi was a little confused for a moment.

"I don't know if I am a teacher. I just want to devote all my life to our Tang Dynasty. I never thought about how big an official I would like to be, and I never thought about whom I would like to be, but I still feel sorry for my teacher."

Li Zhi nodded in a slight understanding, and then felt that he really didn't understand, so he asked:

"How can you show your ambitions if you don't enter the court? The teacher's words seem inappropriate?"

"The Nanyang sorcerer I met before as a teacher said that far away from the ocean, many people with very high knowledge devoted their entire lives to their country, but did not seek rewards, nor did they seek to become officials in the court, but only for the strong country and the rich people, the country has strong national strength, developed technology, and can go to heaven and earth, and do everything."

Ning Wen didn't know how to explain to Li Zhi, so he used the mouth of the Nanyang sorcerer to say what he wanted to say.

"Teacher, what is the development of technology? What is going to go to heaven and earth?"

Although Li Zhi didn't understand a little, he was very excited to hear that there was such a country.

"Technology is science and technology, which is completely different from the classics, history, and collections learned by Zhinu. It is based on thinking, specialized research, and experiments. It is the sum of the knowledge that transcends the world. It not only needs to think, but also needs to do it. Maybe it is a hundred years later, or a thousand years later, and only after thinking and experiments can you make achievements. This is science and technology. As for going to heaven and earth, it is a dream that can be realized after the development of science and technology."

"So that's it. I guess the division commander's weapon supervisor and Tianwei cannon are the so-called technology. Is Zhinu right?"

Li Zhi's reaction was still very fast. After Ning Wen said this, Li Zhi thought of the artillery experiment. After all, he was a prince. The advantages of congenitality and acquired nature were very obvious. If he was put into later generations, he could become a master's degree or a doctorate.

"That is, weapons manufacturing is a very small part of it, but our Tang Dynasty paid too much attention to learning classics, history, and collections, and ignored the action."

"What the teacher said is very much. Now, my imperial examination in the Tang Dynasty is to obtain subjects such as scholars, Mingjing, Jinshi, Junshi, Mingfa, Mingzi, Mingsu, Mingsuan, etc., but Zhinu knew that only Mingjing, Jinshi, and scholars were the three subjects that scholars wanted, among which Mingjing, Jinshi and Jinshi were the first choice for scholars."

Ning Wen was not clear about the subjects stipulated in the Tang Dynasty's imperial examination system. He should have participated this year, but Ning Wen did not go. After hearing what Li Zhi said, he realized that the Tang Dynasty also relied on arithmetic, calligraphy, etc.

"Haha, I'm going too far. The imperial examination and recruiting scholars is the foundation of the country and the way to enter the court to become an official. The meaning of being a teacher is different from entering the court to become an official. I always have to be an official. Haha, being an official is not the only way to contribute to the country and benefit the people."

Li Zhi still couldn't figure out why not being an official can benefit the people. Of course, Ning Wen couldn't tell Li Zhi how high-tech talents such as academicians of the Academy of Engineering and academicians of the Academy of Sciences gave advice to the country. Let Li Zhi slowly digest these.

"Well, what the teacher said is different. Zhinu thinks it is good. In the future, Zhinu will follow the teacher to learn technology, be a scholar who understands technology, and benefit the people of the Tang Dynasty."

Li Zhi's words were burning, and a very confident light emanated from his eyes. Ning Wen patted Li Zhi's shoulder. What do you think? If there is an emperor who is not good enough, he has to work hard to be a scientist. Isn't this a fool who wants to keep a golden rice bowl and jumps into the nest of brans?

"Wrong, Zhinu, it's hard to say this for a while. In short, you have to remember that you should not let the sinisterness of the world affect your mentality at any time."

Seeing that Li Zhi didn't seem to understand, Ning Wen was about to ask, and made a downward gesture and then said:

"You may not understand these words now, but I want you to remember them, and they will always be useful in the future."

Li Zhi nodded nervously, so Ning Wen took Li Zhi to the yard. The wind and rain all over the sky made Li Zhi sneeze twice. Li Zhi rubbed his nose, not knowing what Ning Wen meant.

"Only after the wind and rain, you can see the rainbow. After the cold winter, it is the spring when all things are revived. I will experiment with the Tianwei artillery at the end of the month. I plan to take you to participate."

When Li Zhi heard this, he didn't care about the snow all over the ground and jumped up in the yard happily. Wherever he settled, the snow splashed everywhere, which made Ning Wen's legs look all over. Seeing Li Zhi's childlike habits, Ning Wen's previous gloomy mood also swept away.
