Chapter 300 What Can I Give You in Exchange, My Beloved Disciple?

It only took a short while.

Xue Rengui knew the past stories of Pei Xingjian's father and brother, where he was from, his hobbies, his residence in Chang'an, and his life aspirations.

Pei Xingjian knew that Xue Rengui's name was Xue Li.

He turned a deaf ear to Pei Xingjian's noise and looked at the sand table very carefully.

His Majesty said it very clearly. Although he didn't know if it was Tuyuhun, Xue Rengui also wanted to do some homework early, so he tried not to listen to Pei Xingjian's chattering next to him, but tried to open his eyes and look at the mountains and rivers.

But as a standard family, even if Xue Rengui tried his best, he could only imagine that there were two groups of villains rushing and killing on it.

As for more, he really didn't have any ideas, and it was just at this time.

"Did you see anything?"

A kind voice sounded beside Xue Rengui's ears. Xue Rengui looked at it carefully and said casually:

"The shape of this hill is quite similar to that steamed bun."

As soon as he said this, Xue Rengui felt something was wrong. He looked up and found that there were two more people in the room. One was an old man, and the other was about 30 years old from his eyebrows.

The one asking the question was an old man, with noble clothes and a friendly face.

Xue Rengui's answer made the old man smile and said to the people around him:

"Dingfang, it seems that the appetite of this Hedong general is also quite suitable for Guanzhong."

Su Dingfang smiled, carefully looked at Xue Rengui, whose face was full of uneasiness, and then introduced the two people in the room:

"This is Li Jing, the Duke of Dai, and the Doctor of Military Studies."

There is no need to embellish the record of war, the name alone is already well-known enough.

Xue Rengui did not dare to neglect it and saluted quickly, and Pei Xingjian next to him followed suit.

Li Jing was not polite at all. He picked up a thin bamboo pole and pointed at a large lake on the map:

"This is Qinghai Lake. When the army sets out next year, we must control this place to eliminate the strong enemy and plan for the Western Regions."

"This lake is surrounded by Tuyuhun people on the west, south and north sides, and the Dangxiang tribes on the east. If we climb the plateau to the west, there are also Tubo people ready to move."

"What do you think Xingjian should do?"

The eyes of the three people present were all focused on the short Pei Xingjian. After all, he was only eleven years old now.

Xue Rengui was also full of curiosity. He felt more unreal at this time than yesterday:

Names like Tuyuhun and Dangxiang. He learned about them from stories told by the old people in the village.

As for Tubo Qinghai Lake, he had never heard of it.

And now, listening to the serious words of Li Guogong and the reminder of His Majesty yesterday, he understood it clearly:

Next year, we will go to this place called Qinghai Lake to fight with the Tuyuhun and Dangxiang people.

Xue Rengui had only one feeling: it was too fast.

It was like he had been walking on his own two legs for the previous 16 years of his life, but now the Tang Emperor had rudely stuffed a horse under his crotch, forcing him to start galloping.

Pei Xingjian was not afraid. He looked at the sand table carefully and finally said:

"I have also heard that the Duke led light cavalry to raid Yinshan. The battle was decided. Our Tang army surrounded on three sides and destroyed the various tribes of Najieli."

"But Tuyuhun is not like the Turks. Our Tang came from the east and can only fight on one side. If the sand table is correct, if you want to imitate the method of destroying the Turks, you need to go through Hexi, go around to the Western Regions and then go south to attack Tubo from both sides, which is definitely impossible."

"Therefore, if you control Qinghai, you should make friends nearby and attack far away, bribe the Dangxiang with money and goods, and the army will surprise Tuyuhun directly. The soldiers will be equipped with three horses to exterminate this thief."

"After Tuyuhun is pacified, the Dangxiang will be nothing more than a threat to our Tang."

Looking at the eleven-year-old Pei Xingjian talking freely.

Li Jing's face was full of surprise.

As expected of the old Pei family, his father and brother were both fierce generals. Although they died early, they were influenced by the family and had a lot of insights into military formations.

And maybe it's because he came from Xiuwenguan, he has a wide range of friends, and he is familiar with current affairs and geography, so he has such an opinion!

At this moment, Li Jing looked at Su Dingfang and completely understood why Su Dingfang taught the art of war to Pei Xingjian in history. What a good seedling.

Your apprentice is very good, but he will soon be the successor of Wei Gong's art of war.

Su Dingfang's face was full of pain.

The more outstanding Pei Xingjian was, the more heartbroken he was.

And at this moment, seeing that he had such an opinion at the age of only eleven, Su Dingfang felt that his heart was bleeding. What a good seedling.

But... Su Dingfang also looked at Li Jing:

Why can General Yaoshi compete with Your Majesty for people? It's because of his great merits.

In terms of fighting, he, Su Dingfang, can also do it.

In terms of military merits, aren't there many people around the Tang Dynasty?

So at this moment, Su Dingfang's heart also burst out with pride:

What is leaving a name in history is secondary, he, Su Dingfang, must get his apprentice back!

Xue Rengui's heart sank. He looked at Pei Xingjian, whose height was only up to his chest, and then looked at the sand table:

Why don't I see the words written on this sand table?

Fortunately, this topic was quickly skipped. Li Jing clapped his hands and explained the situation to them:

The military science of the Imperial College is only on trial now, with Li Jing as the doctor of military science and Su Dingfang as the assistant teacher of military science.

There are only two students at present, Xue Rengui and Pei Xingjian.

However, His Majesty has sent letters to all provinces in the world to try to open military examinations.

Those who can stand out from the military examinations will also enter this military class to study military tactics.

Pei Xingjian will also continue to take courses at the Xiuwen Academy, but he only needs to come here to attend classes every few days.

Xue Rengui was given special attention.

After this class, after asking Xue Rengui whether he can read, Li Jing handed him a bag of books:

"Your Majesty has given it to you, and you must finish reading it all."

Xue Rengui stretched his head to take a look, and felt a little dizzy for a moment. The book was full of military books and... mathematics?

Seeing Xue Rengui's questioning eyes, Li Jing nodded with certainty:

"Your Majesty will promote mathematics, and it will be listed as a compulsory course for Xiuwenguan and Guozijian in the near future."

That's all right, Xue Rengui put aside his doubts and took the books with great care.

Just now he asked clearly that Guozijian provided food and accommodation, and he didn't need to go out to make a living.

In this case, then study hard!

After all, apart from anything else, this Pei Xingjian is really too eye-catching.

Looking at the divine generals appointed by His Majesty holding military books with great care to find accommodation, Li Jing was full of relief:

"They are all talents that can be cultivated."

Su Dingfang nodded in agreement: Who said it wasn't?

Then he and Li Jing went to Wulei Temple together.

Later generations would ridicule the Kuang Dao Mansion as a sweeper, which shows that everyone knows that the Kuang Dao Mansion is really idle.

In this case, Su Dingfang also chose to follow Li Jing and planned to go and see the gunpowder together.

However, after leaving the room, the first person he saw was the high-spirited Yan Lide.

Li Jing greeted him:

"It seems that Master Yan's lecture is also going well."

Yan Lide bowed gratefully. After testing the gunpowder in the north of the city, the first thing he thought of was to start with the General Works Bureau and mass-produce this thing.

Originally thought that it would cause Li Jing's dislike, but unexpectedly, the Duke of Dai was quite broad-minded and went with him to find His Majesty to talk about the gunpowder.

Now the Wu Lei Office, which is affiliated to the General Works Bureau, has also initially built a framework, which is inseparable from the help of Li Jing.

So Yan Lide also responded quite friendly:

"Duke Dai is full of smiles, it seems that Xue Rengui and Pei Xingjian are both worthy of their reputations?"

After saying that, Yan Lide thought for a while and gave out something:

"This is the Yang Sui used for teaching students, Duke Dai should be able to use it."

Li Jing took it curiously, and it was cold to the touch. This small piece of glass had been polished, and each side was high in the center and low on the edges.

When he put it in his hand, he was surprised to find that through this strange-shaped glass, the lines in his palm became much larger and could be seen very clearly.

But Li Jing was still curious about its name:

"Is this Yang Sui too?"

Li Jing was not unfamiliar with Yang Sui, because Taoists often used it to make elixirs.

It is not complicated to make. It is made of copper in a depression shape, and then the inner wall is polished smooth. When the depression faces the sun, the light can be gathered in the depression.

At this time, handing over something like hay can ignite it.

Nowadays, it is occasionally brought during marches, just in case you get into a desperate situation.

After Li Jing and Li Shiqi closed the Wulei Temple, they strictly controlled the fire and banned the Yang Sui.

But this glass Yang Sui is very different from the copper Yang Sui.

Yan Lide demonstrated the usage to Li Jing on the spot. Put it in the sun to let the light gather a little, put some dry grass, and it will burn in a moment.

"This thing is convenient."

This can be seen at a glance. Compared with the copper Yang Sui, this thing is many times more convenient.

Not only is it easy to carry, but the effect of doubling the vision also makes Li Jing very happy.

Moreover, Li Jing looked up at the sky and suddenly thought, can't this thing also be used for the timed ignition of gunpowder?

For example, if the thief Liao passes by this place at 2:00 pm tomorrow, the gunpowder can be buried in advance at night, and the Yang Sui can be set up according to the direction of the sun at 2:00 pm...

Although this situation is rare, there should be more uses.

And Li Jing also found that this seems to involve mathematics, which is really the king of science.

Stroking the glass sunflint in his hand, Li Jing turned to ask about another object that he was more concerned about:

"What about the telescope?"

Yan Lide sighed:

"We have to wait."

He came to the Imperial College to give lectures, and the method he claimed to be "famous for thousands of years" was the method of the telescope.

To put it nicely, it was because "one person's plan is short and everyone's plan is long."

To put it realistically, it was because the General Works Bureau was running out of manpower.

The Five Thunders Office was newly built, and the Navy's affairs had to be studied. The methods of innovating weapons, armor and horse armor for future generations had to be tried out, and the methods of steelmaking had to be improved.

And now we have to study how to mass-produce iron nails.

Since the founding of the country, the General Works Bureau has never been as busy as it is now.

So after trying to prioritize these things, Yan Lide simply chose to let the students of the Imperial College do the work for free...to contribute to the country.

After all, the research on the telescope is not like iron smelting.

Iron smelting requires blacksmith experience, furnace research, and support from iron workshops.

Theoretically, this telescope only needs a few pieces of polished transparent glass to try.

So Yan Lide sent the polished transparent glass over, and vaguely pointed out the direction, so that the students of the Imperial College could try it in a certain direction.

At the same time, he also planned to advise His Majesty that the General's Office might also need its own school.

Opening the altar, offering a book:

"My Chinese Ancestors"

Su Chen traveled through time and became the youngest son of a marquis of Yan State. With the tablets of Chinese emperors of all dynasties, he summoned the emperors who had once dominated the world and their powerful generals to help.

"I started with a broken bowl, and you are like standing on the clouds compared to me!" Zhu Yuanzhang shook his head at Su Chen who was not doing well.

Liu Bang stared at the chair under Su Chen's buttocks without blinking, "Let Ji have another addiction, this Chixiao sword is given to you, and Han Xin and Fan Kuai will lend it to you!"

"Is there any elixir of life in this world?" Ying Zheng looked at the huge geomancy map, his eyes gradually brightened: "In this world, with so many countries, when will we be able to have the same track and the same writing system?"

He waved his hand: "Unification!"
