Early the next morning, the whole Zhangjiazhuang people got up early.

Before dawn, the old and young in Zhuangzi got up, because Zhang Yi was going to travel again today, and Zhang Yi traveled, and many young adults in Zhuangzi naturally had to follow Zhang Yi.

However, this time Zhang Yi confessed, and let Wang Wu pick it, but the number of people is as small as possible, but the combat effectiveness must be good, and everyone must be shrewd and capable.

Zhang Yi didn't have much appetite, he just ate and drank a little casually for breakfast, coping with his stomach, and then came out directly.

Looking at Xu Rou Yun'er and Yang Su and the others who came out, as well as the trembling old lady who walked at the back, Zhang Yi suddenly felt that he had a great responsibility.

If he can't successfully complete this task, then this big family may have to suffer with him in the future.

However, such a large family of people also made Zhang Yi feel fulfilled, if there were so many people missing in his life, it would still be a little empty!

It is not appropriate to say much about parting, it is easy to be sad to say more, Zhang Yi just secretly kissed Xu Rou who had just passed the door, and then gave the old lady and Yun'er, Yang Su and others a smile and immediately turned around and stepped on the war horse.

Today he was not riding in the carriage as usual, and today, he changed his horse, because this time he went out and was no less dangerous than the last time he went to Shuofang to fight the Turks, at least for him.

Wang Wu had already counted the number of people, and at this time they had all said goodbye to their families, and as soon as Zhang Yi got on the war horse, those young men immediately roared out of the Zhuangzi.

On the eleventh day of the month, Zhang Yi and Wang Wu and others were behind them, and dozens of horses roared in the direction of Chang'an City.

Riding a war horse and riding a carriage, the speed is not the same, it usually takes more than an hour to ride a carriage, but now riding a war horse at full speed, it only took about half an hour, Zhang Yi couldn't help but sigh that it was really comfortable and easy to make mistakes!

And when Zhang Yi and the others rushed to Chang'an City, Xu Jingzong had already taken people to wait there.

Since their actions were extremely secret this time, they couldn't use the official identity of Datang, and the identity given to them by Li Er was just a businessman, so they had to use the identity of a businessman to carry out the task.

Of course, Li Er also gave them some things to prove their identity, but those things are basically useless to Zhang Yi and them, unless their identities are revealed and they are hunted down by the Tubo people, only at that time, these things can make them ask the Tang army for help, and let the Tang Dynasty send a large army to rescue them.

Thinking about the roof of the world, Zhang Yi's heart was a little panicked, what if there was altitude sickness, people in this era may not know what to do.

Now he can only pray that he will not have any altitude sickness at that time, and if he does have altitude sickness, it will be more difficult to do.

However, Zhang Yi has never been a person who accepts his fate, the bridge to the bow of the ship is natural, and he believes that there will always be a way when the time comes.

Now, all they have to do is to hurry to the border between Tubo and the Tang Dynasty, and then use their own means to open up trade with the Tubo.

Yanba is the foundation of the country, and Datang controls it very strictly, but Li Er has already opened the door for them to make it convenient, as long as they open their mouths, they don't have to worry about how much they want.

There are also things like Tibetan mastiffs and some spirits, these things Li Er has also let people prepare, and when the two of them rush to the border to open trade, these things will be ready.

Fortunately, Li Er provided all these things, otherwise if they were really allowed to operate like a businessman, the ghost knows when the economic war against Tubo would be effective this time.

If the time is too long, it is better to let Datang recuperate for a few years, after a few years, Datang will definitely be strong, and it will be easy to defeat Tubo at that time.

The distance between the border between Chang'an and Tubo is actually not too far, Shuzhong and Xiliang are bordering Tubo, if Zhang Yi and they hurry up, it is estimated that they will be able to arrive in only three or four days.

However, looking at Xu Jingzong's figure, Zhang Yi still dispelled the idea of speeding up.

Anyway, hurry up, they will only arrive a day or two late at most, there is no need to rush so much, when the time comes, Xu Jingzong's body will be exhausted, and then the gains outweigh the losses.

Qingtang is a major horse farm in the Hehuang region, and it is also the main area of trade between the Tibetans and the Han Chinese, who often exchange their horses and yaks for salt, pig iron and other materials for their daily needs.

The most important thing is that Qingtang is now controlled by the Tubo people, so Qingtang has not been sacked by the Tubo people, but due to the riots in Tubo, Qingtang has begun to be a little deserted.

The Tibetans plundered everywhere, and those Han people, especially the merchants, who dared to go to Qingtang to do business, now when they arrived at the border, they would face the danger of being robbed of goods, or even losing their lives, who would be willing to take this risk to cross over there.

However, it is precisely because of this that the price of Qingtang is soaring now, and it was originally five catties of salt that could be exchanged for a good horse, but now it has become three catties of salt for a good horse.

There is no way, without salt, people can't live, and although Tibet itself also has salt manufacturing, but the scale is too small, once the trade with the Han people is interrupted, many people in their country will face the dilemma of not having salt to eat.

However, now the Tubo people are still looting the border of the Tang Dynasty, which also allows them to loot a lot of salt, for the time being, they can still meet the domestic supply of salt, so the contradiction has not broken out.

Zhang Yi: Their destination this time is Qingtang!

Although there are now a lot of Tibetan soldiers on the border, Zhang Yi and Xu Jingzong also have a total of more than 100 elite soldiers, although these soldiers cannot be said to be all of them able to be a hundred, but they are also very elite.

Of course, Zhang Yi and the others will not be stupid enough to clash head-on with the Tubo people, after all, they are doing business, and these horses are just used by themselves to ensure their own interests.

However, if they want to go to Qingtang, they can't go directly like this, otherwise, they will really just send food to those Tubo people, after all, those Tubo people only have food and money in their eyes now.

If they dare to rush over with so many supplies, it will be a sheep in the mouth of a tiger, and there is no possibility of returning.

However, people die for money, birds die for food, although there has been friction between Datang and Tubo over the years, but trade has not been broken, Zhang Yi and they still have a way to contact the high-level of Tubo.

As long as they come into contact with some Tibetan nobles or lords or something, and can have their protection, the safety factor of Zhang Yi and his party will be much higher.
