The two had already determined the basic idea of ​​economic war. They mainly used salt basins, using the large amount of salt basins left by the Tang Dynasty to dump them into Tubo, and then attacked the local salt manufacturing industry in Tubo. Then when the Tubo people gave up their salt manufacturing industry and used all the low-priced salt from the Tang Dynasty, the Tang Dynasty could immediately attack the Tubo soldiers.

At that time, they only need to suddenly stop supplying salt to Tubo, and the Tubo people will immediately become in chaos. At that time, there will be chaos in the country and a nationwide turmoil. They do not believe that those Tubo soldiers can still fight the Tang army at the border with peace of mind!

Salt is a necessity for daily life and is the focus of their main attacks, while others, such as domesticating Tibetan mastiffs, and then selling these Tibetan mastiffs to those Tubo nobles at low prices.

By the way, most of the soldiers in the Tubo army were in the hands of these noble leaders. When there was war, each leader would summon the soldiers and then go to the designated location to gather. When there was no war, these nobles would train their own troops, and some would use some soldiers as militias to let them farm and grazing.

Tibetan mastiff itself is a product on the Qinghai-Tibet Plateau and is deeply loved by the locals. If they can tame a batch of Tibetan mastiffs and then give it to or sell it to those Tubo nobles at a low price, then Tibetan mastiffs will inevitably become the new love of some nobles.

There is a saying that it is easy to go from frugality to extravagance, but it is difficult to go from extravagance to frugality.

Once those great nobles and leaders like to have fun, the training of military soldiers will inevitably be slack. In this way, the combat effectiveness of the Tubo army will naturally be reduced to a higher level. In the future, the Tang soldiers will have the advantage when facing Tubo soldiers.

Not only these, Zhang Yi and his team also planned to use some inconspicuous things to slowly disintegrate the industrial chain of Tubo. When the war begins, as long as the Tang Dynasty stops supplying Tubo, the industrial chain of Tubo will inevitably collapse.

Never underestimate the industrial chain. It is like a chain. As long as you break one of the links, the entire chain will be ruined. No matter how good the rest of your chain is, it will be useless.

Once Zhang Yi and his friends succeeded in these plans, they would not even have to attack Tubo from the Tang army, and the Tubo people were willing to surrender themselves.

The two of them roughly explained their methods to Li Er. After Li Er felt that there was no problem, they asked them to execute immediately.

Zhang Yi and Xu Jingzong walked out of the palace silently. They were silent all the way and walked outside the palace. They looked at each other and breathed a sigh of relief.

If Li Er had been concerned about sympathy or other reasons, he would not do anything to these heroes, but now Li Er has become too many, and he has become a pure emperor.

And when Zhang Yi and Xu Jingzong left, a gentle voice came from behind Li Er.

"Your Majesty, is this really good for Zhang Yi?"

Changsun still likes to follow Li Er as before, but now he is almost at the delivery period and cannot serve Li Er, nor can he stand beside Li Er, and can only lie behind.

"There is nothing good or bad, even if he hates me, I have to do this for the sake of the Tang Dynasty and the people. Besides, you don't know that Zhang Yi is the kid. If you don't use the method of threatening him, he will not submit at all.

Do you have the heart to waste your time watching him? Do you have the heart to watch him think all day long about how to make money and be a rich man?”

After Li Er's words, Changsun had no choice but to accept it. She knew that Li Er had no choice but to do so. No matter what decision Li Er made, Changsun would support him without reservation!

As expected, people will change. In fact, compared with a founding monarch like Liu Bang, Li Er is still good. At least Cheng Yaojin and Qin Qiong and others who follow him live a good life.

However, for the sake of achievements and the Tang Dynasty, Li Er has completely used people as tools.

And here Zhang Yi quickly said goodbye to Xu Jingzong and returned to Zhangjiazhuang.

Because the two of them had already stated the plan in front of Li Er just now, and they had made coordination, and the division of labor has been made for who should do, so they just need to follow the plan.

This time Zhang Yi returned to Zhangjiazhuang was the last time he returned to Zhangjiazhuang before completing the task.

Tonight, he will stay at home for one night, and early tomorrow morning, he will follow Xu Jingzong to the border.

When returning to Zhangjiazhuang, Zhang Yi still needs to prepare a lot of things.

This time he and Xu Jingzong had great authority to go to the frontier, but they could not reveal their identities. As the most secret task of the Tang Dynasty, the content of the task could only be ruined by the two of them. Therefore, this time going to the frontier was equivalent to going to war.

The first thing Zhang Yi did when he came back was to ask Wang Wu to gather some of the soldiers in the village, and then select some capable men to serve as his guards and go out with him. Those selected men would also stay at home for one night tonight.

The matter of the guard team was settled, and Zhang Yi asked Lao Zhong to stay in Zhangjiazhuang and asked him to contact Fatty Bu. At that time, they would find a way to follow him to the border.

Although this time, the Tang Dynasty sold salt to Tubo at a low price, the business opportunities were still very great. The more dangerous the place, the more profitable it was. Therefore, Zhang Yi planned to lead the fat man to work with him.

The abundant production of Huo and other things in Tubo must be very attractive to Fatty Bu. If he can make good use of Zhang Yi's relationship and make a few more trips, he will definitely make a big profit.

As for Zhang Yi's proposal, Fatty Bu never refused, so Zhang Yi wanted to leave Lao Zhong in the mansion. When Fatty Bu comes, he would prepare immediately.

In addition to these, Zhang Yi also prepared some other things and asked Yue Shiyi to prepare some things. After all, Yue Shiyi is his own personal guard now.

It was only afternoon when Zhang Yi returned to Zhangjiazhuang, and after he arranged everything, it was already dark.

The dinner tonight was uncomfortable and the atmosphere was a bit dull. Although Zhang Yi had adjusted the atmosphere repeatedly, the dining table was still a little depressed.

Fortunately, I finally got over it. After dinner, Zhang Yi stopped taking a walk. After running to take a shower, he went straight back to the room.

This time will be the last time he has been at home during this period, so he must be hardworking.

Zhang Yi also took the initiative tonight. In addition to Yang Su, whose belly has gradually grown bigger, Zhang Yi also pulled Yoona over.

Looking at the two shy women on the bed, Zhang Yi smiled grimly and rushed forward.

"Tonight, the construction will officially start!"
Chapter completed!
