Time soon came to the end of the year, this day the prince Li Chengtang accompanied by Huashan went to the Royal Institute of Technology in Yushan, Li Chengtang was eight years old immediately, he had a kingly temperament, and he was courteous, both civil and military, and won the unanimous praise of the ministers in the court.

Now there are four schools in Datang that are more famous, one is the Royal Academy, which Li Jun prepared for the royal children, and in the future, Li Chengtang will also take two days a week to go to class; The second is Gantang, Gantang mainly trains new science and technology scholars, not to mention military schools, which train officers.

The last one is the Royal Academy of Technology, this college is very low-key, and it is not very favored by the ministers of the DPRK and China, because this school mainly trains not scholars, but technical officials, but in Li Jun's heart, this school is the most important school in the Tang Dynasty.

This school Li Jun believes that the future will change the world, so Li Juncai asked the heir of the future empire to go, if Li Chengtang, who is the crown prince, does not pay attention to it, then even if Li Jun does it well, it is useless, because Li Jun will not live forever, so in the end, the Tang world will still be in the hands of Li Chengtang.

Li Chengtang is very excited today, because Li Chengtang's schoolwork has obviously increased during this time, so he got a chance to go out today, and Li Chengtang is very happy.

Escorting him to was He Jun, the commander of the Imperial Forest Army, He Jun could be regarded as watching Li Chengtang grow up, so he was very close to this little prince, and the two chatted while hurrying, and soon came to Yushan City.

The Royal Institute of Technology is located outside Yushan City, and the surroundings seem very bleak, Li Chengtang got out of the carriage, and Huashan greeted him and said, "The ministers are participating in His Royal Highness the Prince." ”

Li Chengtang looked left and right at the environment here and asked with a smile, "Doctor Hua, why is this place so remote?" Lonely, I heard that in Yushan City, Gantang is full of people all day long, and there are high-rise restaurants such as Zhuangyuan Building next to it, which is very lively. ”

Hua Shan replied: "Your Highness, there are many achievements in the College of Science and Technology that are not suitable for research in crowded places, and if there is any accident, it will be a great disaster." ”

Li Chengtang opened his mouth wide, very shocked in his heart, but there was a trace of disbelief in his confusion.

Hua Shan didn't break it, but said with a smile: "Your Highness, go in and walk around with your ministers, and you will know." ”

"Okay, then trouble Doctor Hua to lead the way."

Huashan took Li Chengtang into the academy, the first thing that came into front of Li Chengtang was a huge stone tablet, on which were written four big characters "rejuvenating the country through science and education", this is written by Li Jun, Li Chengtang looked at these four words and felt a little touched in his heart, rejuvenating the country through science and education, his father also explained to himself, but he didn't pay much attention to it at that time, in Li Chengtang's eyes, the rise and fall of an empire still depends on whether the monarch is mediocre? whether the minister is virtuous or not, etc.

Hua Shan saw that Li Chengtang had some understanding, so he explained: "Your Highness, when you transfer the entire academy, you will find Your Majesty's Shengming, and you will understand the true meaning of these four words. ”

Li Chengtang's careful thinking was broken by Hua Shan's words, and he arched his hand in embarrassment and said: "Doctor Hua, Lone doesn't mean that. ”

"Your Highness, please come forward." Hua Shan said with a smile.

The two first went to the Agricultural College, where some new crops are planted, Li Chengtang is no stranger to crops because he has learned how to identify plants with Yuan Zhan, but looking at the green appearance here in winter, he can't help but be a little surprised.

Hua Shan smiled and asked, "Your Highness, do you see any difference?" ”

"Why do the crops grow so well in winter?" Li Chengtang hurriedly asked.

Hua Shan pointed to the huge glass on it and said: "Your Highness, these transparent glasses are covered with cotton, which can play a role in keeping warm, so the environment where the crops here are located is like summer, and they can naturally grow strongly." ”

Li Chengtang noticed that he was in a huge glass room, and looking at the glass on it emitting colorful light under the reflection of the sun, he couldn't help but feel a little dazed.

Hua Shan hurriedly grabbed Li Chengtang's arm and said, "Your Highness, don't look at it for a long time, it's not good for your eyes if you look at it for too long." ”

Li Chengtang asked embarrassedly: "Doctor Hua, I heard that in the last auction, the two glazed giant wolves were exchanged for four thousand cows, and now that so much glaze is used here, is it a bit extravagant?" ”

"Haha, Your Highness doesn't know, in fact, the Yin and Yang family has long made pure glass, this kind of glass is not valuable, it's just made of a pile of sand, last time the two glass wolves were actually taken by His Majesty to fool the grassland people, wait a few years, this thing can be bought by poor households." Hua Shan said with a laugh.

"Ah, really? Doctor Nahua hurriedly took Gu to take a look, Gu was very curious. Li Chengtang said in surprise.

Hua Shan shook his head and said: "Your Highness, that's a trail, don't worry about it first, what your subordinates take Your Highness to see is the most important heritage of the Tang Dynasty, please be mentally prepared for Your Highness." ”

Li Chengtang didn't dare to underestimate the College of Science and Technology, and immediately nodded when he heard this.

Huashan first took Li Chengtang to see the loom, and heard that this simple machine can make cotton into cotton cloth and wool into wool, Li Chengtang was very excited, stroked these looms and said excitedly: "Hua Shenyi, won't the grassland become a treasure land in the future, the herdsmen of the grassland only need to raise sheep, and then sell the wool to our Datang, so that the grassland and the Central Plains have formed a mutually beneficial situation, maybe the grassland problem that has plagued the Tang Dynasty for a hundred years can be solved." ”

"Your Highness is wise, Your Majesty has already begun to implement this in the land of Yanzhou and Liaozhou." Hua Shan said with relief.

After seeing the production method of gunpowder, Li Chengtang said with emotion: "I didn't expect that the gunpowder that can open mountains and split rocks is only made of ordinary materials such as nitric acid, charcoal and sulfur. ”

"Your Highness, this is the Yin-Yang Family's research on the unity of Yin and Yang, everything in the world has its own characteristics, if these things are mixed together, it may produce huge energy." A famous man of the Yin and Yang family next to him explained with a smile.

Li Chengtang arched his hand at the Yin and Yang family's famous house and said, "Be taught alone." ”

In the end, Huashan took Li Chengtang to the Medical Research Institute, and Li Chengtang was surprised to find that people here were wearing protective clothing in and out.

Li Chengtang asked: "Doctor Huashen, are these clothes the protective clothing you wore when you went to Xuzhou to fight the epidemic?" ”

Hua Shan nodded and said: "Your Highness, exactly, Buddhism says that one flower is one world, one leaf and one Bodhi is very reasonable, Your Highness, please get dressed, go to the microscope inside, you can find that there are many tiny little insects in our lives, some small insects are harmful to the human body, so people will get sick after inhalation, some are harmless to people, and some are even good for the human body, this is a huge cultural system, and we are just getting started now." ”

Li Chengtang couldn't help but feel uncomfortable after listening, but he still didn't control his curiosity and followed Hua Shan into the house, under the microscope, Li Chengtang really saw a lot of small insects, of course, there are some interesting things, looking at Li Chengtang excitedly like a child, looking left and right, Hua Shan couldn't help but admire Li Jun in his heart, His Royal Highness the Crown Prince is the future heir of the empire, if you want to continue to study these things forever, you have to cultivate the interest of the next generation of young people in the empire.

In the evening, Li Chengtang went back unsatisfied, and at dinner in the evening, Li Jun asked Li Chengtang: "Tang'er, how do you feel about going to the Institute of Science and Technology this time?" ”

As soon as Li Jun asked, Xiao Meier also put down her chopsticks, and also looked at Li Chengtang to see how he answered, Li Chengtang thought for a while and replied slowly: "Father, Erchen thinks that the importance of the College of Science and Technology is more important than Gantang, and there are novelties everywhere, so Erchen wants to enter the college to study." ”

Li Jun nodded with satisfaction and said: "Haha, yes, it's good to have this awareness, but it's okay to study, you are the future emperor, you can't work hundreds of jobs, but I allow you to visit the Institute of Science and Technology once a week." ”

"Thank you, father, for making it perfect." Li Chengtang replied happily.
