However, although the speed of the mutant beast is very fast, it is still a little slower than that of the tank, and the tank is still running, turning the muzzle around, aiming at the mutant beasts and starting to bombard them fiercely.

Boom boom!

There was a violent explosion, and the shells with thick and thin arms fell like raindrops. Among the mutant herds, the flowers composed of flesh, blood and fragments of shells immediately bloomed.

However, compared with the huge number of mutants, this kind of shell basically can't cause any effective damage. On the contrary, it angered those mutants even more and rushed to the tank team one by one.

Now, it's not predatory, it's anger.

But what Wang Yi wants is to keep these mutant beasts angry. Otherwise, how can they attract them to a further distance?

The tank didn't advance at full speed. It was still hanging the mutant herd. At least it ran hundreds of kilometers in the opposite direction. It was only on a Gobi desert that the tank team suddenly increased its speed. The mutant beasts were absolutely exhausted at this time. They could only watch the tank team disappear in front of them, but they couldn't catch up.

Moreover, these mutant beasts don't know how to return at all. One by one, they either form a small group or act alone and scatter in the endless Gobi desert.

After one night's rapid march, Wang Yi returned to the gathering place of Dahan with his tank team in the early morning of the next day.

As soon as he came back, Balu, the leader of Dahan's gathering place, was very excited. He was very worried that something might happen to Wang Yi. In that case, materials and grain would no longer exist.

Seventy trucks are full of iron ore, at least a few hundred tons. The content of these iron ores is extremely high. Basically, the iron extracted from each ton of ore can reach about 60%. As for returning to the gathering place, and then refining the special alloy used to make tankers and rifles at the Lianfeng mountain Army factory, it is estimated that it will be as low as about 10%.

There is no way to do this. After all, the steel used to make weapons needs greater strength, and all kinds of other metals need to be added. Therefore, there seems to be a lot of ores in the hundreds of tons. In fact, it is only the amount of several tanks at most. But this is just the beginning. In the future, every half a month or a month, Wang Yi would send a transport team from Daqingshan gathering place to bai'e gathering place and then to Dahan gathering place to transport materials continuously to Daqingshan gathering place.

As for the rest of the trucks, they were all loaded with barrels of gasoline, diesel and so on.

Because Dahan is a gathering place where oil can be refined with great efforts, there is no need to bring oil back directly, which is more troublesome.

However, what Daqingshan has paid for is food, weapons, and various living materials.

Two days later, the convoy finally returned with a full load, leaving some of the original food and other things to the Dahan gathering place, as well as five tanks and a company of 150 soldiers.

After all, we have already taken a lot of good things from others. If we don't leave something behind, we can't get by.

That company was completely responsible for teaching the troops in the area where Dahan gathered, but it would never stay here forever. About every two or three months, Wang Yi would send soldiers to replace them.

After two days of marching, the motorcade returned the same way and finally arrived at the gathering place of bai'e.

At this time, the gathering place of bai'e has completely changed. Because of mining and other reasons, the population of the other four gathering places has completely moved here.

Now, they have formed an organization similar to the alliance. Although the five gathering places live together, they have five leaders to manage their own population. They are divided into five areas, mining ore, breeding cattle, sheep and livestock. They all pay dividends separately.

In the past half a month, the Daqingshan gathering place had a deep and friendly exchange with the bai'e gathering place. Wang Yi even found many survivors in the gathering place.

They take their trucks, pull the grain and living materials purchased from Daqingshan gathering place, and then go to bai'e gathering place to exchange livestock with some local herdsmen, or some unique things on the grassland, such as horse milk wine, or some exquisite ornaments.

Of course, their exchange is limited to these. Weapons and minerals are firmly held in the hands of the officials of Daqingshan gathering place and bai'e gathering place. Anyone who dares to exchange in private will violate the rules of Daqingshan gathering place, ranging from fine to labor reform.

However, in addition to these, Wang Yi also saw some managers who originally belonged to the Construction Department of Daqingshan in the gathering place of bai'e.

At the request of Shi Weimin, the leader of the gathering place of bai'e, they came to help build the city walls and houses in the gathering place of bai'e.
