After the court discussion ended, the civil and military ministers retreated to the court, and Zhang Yi also retreated to the court like other ministers and left.

Xue Li stayed in the palace for one night, but he could not live in the palace all the time. Now he is not qualified. Even if he is qualified, he cannot live in the palace at will.

So, it was natural that Xue Li followed Zhang Yi and left.

Xue Li was very grateful to his mentor. Although he didn't know how he knew him, he was recommended by him now.

"Go back with me, it will be more convenient when your Majesty wants to summon you."

Zhang Yi knew that Xue Li was suddenly summoned to Beijing and there was definitely no place to live, and he was the one he recommended, so it would be reasonable to follow him back.

But now, Zhang Yi obviously didn't want to take Xue Li back to Zhangjiazhuang so soon.

During this period, Cheng Chumo, Tang Peng and others helped him a lot. Just by asking them to follow him to lobby many nobles in Chang'an City, he owed them favors.

Of course, all this is for Xue Li, and it can also be regarded as Xue Li owes them a favor.

Therefore, after resigning from the court, Zhang Yi took Xue Li to Duke Cheng's mansion with him.

Cheng Yaojin was very interested in Xue Li recommended by Zhang Yi, so after Xue Li arrived at the Duke's Mansion, he naturally had to be called to him by Cheng Yaojin over and questioned him.

In fact, Cheng Yaojin was still thinking about the safety of the soldiers on the front line. Through this discussion, he could see that if there were no major variables, then Xue Li was likely to be the pioneer of this Eastern Expedition.

So he had to talk to Xue Li, teach him some experience and knowledge so that he could go smoothly by then, and also allow the Tang army's war to go smoothly, and the soldiers could sacrifice less and shed less blood.

Xue Li was pulled over by Cheng Yaojin, and Zhang Yi was not as good as that. Cheng Chumo and a few foodies were unceremonious and dragged Zhang Yi to the kitchen.

It is rare that Zhang Yi has been staying in Chang'an during this period. They don't want to miss this opportunity, otherwise they might even be able to eat a meal made by Zhang Yi in the future.

When they were greedy, they could go to Zhangjiazhuang to have a meal, but this kind of thing could only be occasionally, and they could go there every day, so they planned to pull Zhang Yi to cook for them more now.

By the way, let your chef watch it a few more times and strive to make better dishes in the future.

When the food is ready, Cheng Yaojin and the others naturally have to come and eat together. Cheng Yaojin still likes Zhang Yi's craftsmanship very much.

Cheng Yaojin, Cheng Chumo, Zhang Yi, Xue Li and Tang Peng and others ate around a table.

This meal was also the time when Zhang Yi introduced Xue Li to the table. If Xue Li wanted to stay in the army in the future, he would have to have some of his own friends and supporters.

And now, isn’t it a good opportunity?

The Cheng family's reputation in the army, coupled with Tang Peng and others, is enough to help Xue Li open up the situation in the army.

It means that Zhang Yi paved the way for him, so he would be much easier for him to walk the next path.

What a smart person Xue Li is. Although he is only in his twenties, he understands Zhang Yi's intentions.

After drinking and eating, Zhang Yi and Xue Li rushed back to Zhangjiazhuang before dark.

There is a curfew in Chang'an City, and Zhang Yi doesn't want to stay in Chang'an City. Although there are houses to live in Chang'an City, his home is in Jingyang, and Li Hui and others are in Jingyang. He has to go back to Jingyang to be considered home.

The housekeeper Lao Zhong was driving the car, and the two of them talked about the current situation and some other issues in the carriage and rushed to Zhangjiazhuang.

In the next few days, nothing happened in Chang'an City, and Li Er did not summon them to the palace.

However, Zhang Yi knew that this was just the tranquility before the storm.

Before a war, preparations must be made, and now, Li Er should be preparing for the next expedition in the palace.

Li Er needs to plan one by one to mobilize troops and generals, and he not only needs to choose a vanguard, but also other generals, but also Li Er and some generals and ministers of the army to bother.

So Zhang Yi took advantage of this time to let Xue Lifang relax.

The most important thing is that Zhang Yi must take advantage of this period of time to allow Xue Li to freely apply gunpowder and ammunition to the war.

Although Li Er was the king of the Tang Dynasty, he was not a general after all, and he needed to go to war, so Xue Li was a good choice.

In the next twenty years, Xue Li will be a capable general of the Tang Dynasty, so Zhang Yi planned to make the Tang Dynasty transition from the overlord of cold weapons to the universal use of cold weapons through Xue Li's promotion.

Xue Li was also very interested in the gunpowder bullet after hearing about the role of gunpowder bullets. However, the military was extremely strict and they had no way to get in touch with gunpowder bullets. He could only hearsay and find out some, but he could not really understand gunpowder bullets.

And now, the Mingzhe of the gunpowder bullet is standing in front of him, how could Xue Li miss this opportunity?

Therefore, it was very easy for Zhang Yi to teach Xue Li some knowledge about hot weapons.

One is willing to teach and the other is willing to learn. With two wishes, things will go very smoothly.

Moreover, Xue Li is a very smart person. Zhang Yi only needs to explain it to him, and he can know the principles, and usually he can learn from one example and apply it to other things.

Zhang Yi even felt very enjoying the professor's smart guy. Now he finally knows why some people like to teach. If they can meet a smart student, that feeling will be really good.

Xue Li has such strong learning ability, and Zhang Yi also wanted to take advantage of this period of time that the war has not yet broken out and teach him more about hot weapons. After all, if Xue Li can promote these things in the future, it will be much faster for him to promote them yourself.

The most important thing is that he finds it troublesome, and he teaches Xue Li, so he doesn't have to be so troublesome.

When the Tang army showed hot weapons, who could compete with them at that time?

No!

Under Zhang Yi's professor, Xue Li has mastered more and more knowledge of thermal weapons, especially for gunpowder bullets. He has almost been able to apply it to many aspects, and some places even Zhang Yi did not expect.

Time passed by, and the two gradually evolved from Professor Zhang Yi at the beginning to the discussion between them.

If they are given more time, they know what new products they can discuss.

However, at this time Li Er had already prepared almost all the time, and the transfer of food, grass, weapons and soldiers had already begun.

The entire empire began to move, and the war machine gradually started!
Chapter completed!
