Huaxia's ability to use computer information systems to finely manage the registered population is something Tuoba Liwei does not know.

As long as the people in Suo Tou entered Ping'an City, their basic information would also enter the population information system of Huaxia Kingdom through various channels.

Whether the poll tax paid by Tuoba Liwei includes all the population of Suotou, Li Yan has no way to verify, and the amount of tax paid is also determined by Suotou himself.

However, Li Yan didn't care about this, because the taxes paid by Suo Tou could be regarded as dispensable for Huaxia Kingdom, and it had no significant impact on the construction progress of Ping'an City.

The significance of collecting this tax is that while the Huaxia State provides a certain degree of security to Suotou, the ordinary members of the Huaxia State also gain the right to walk freely on the territory of Suotou.

Moreover, Suo Tou also has the obligation to ensure the personal and property safety of these Chinese people.

Otherwise, Ping'an City has absolutely reason to ask for compensation, whether it is cattle, sheep and other materials, or the population of Suotou, it is the subject of compensation that Ping'an City can accept.

Moreover, the people sent by Ping'an City to sit in Suotou are actually equivalent to setting up several information collection stations on the territory of Suotou.

Every day, they will summarize the collected information to Ping'an City through the transmitter, so that Li Yan and them can adjust the relevant policies in a targeted manner.

The spread of this information is invisible and untouchable to these Xianbei people who protect their safety, and they don't even know what this magical thing that can communicate thousands of miles will work.

So much so that those official members of the Huaxia Kingdom who were responsible for collecting information could send all the information they had collected to Ping'an City in the activity room where they were resting.

For example, the number of people they see, the number of cattle and sheep, as well as the data of the meteorological environment such as temperature, humidity, wind speed, and sunshine hours.

For Tuoba Liwei, they didn't know what they were doing, only that everything seemed so delicate and mysterious.

……

As long as there is interest, information always spreads so quickly.

The obvious changes in the living standards of the people of Suotou, as well as the abundance of salt, iron, tea and even fresh vegetables in the tribe, naturally attracted the attention of the surrounding tribes.

They used the caravan to send back to their respective tribes with the abundance of supplies in Suotou, which attracted the covetousness of some of the surrounding tribes.

Among these tribes, the strength of Suo Tou is actually not bad.

If everyone's standard of living is about the same, there is nothing to live a miserable life, because everyone lives like this, and they can't fight for a small ration.

But after Suotou used the cattle and sheep in his hands in exchange for a large number of daily necessities provided by Ping'an City, their quality of life was significantly different from that of the surrounding tribes.

If Suotou is the most powerful tribe in the steppe, then the other tribes can't think otherwise.

They will only do everything they can to integrate their tribe into this powerful tribe, so as to get the blessing of this powerful tribe and indirectly improve the quality of life of their tribe.

However, the wealthy Suotou was not the most powerful tribe in the steppe, and such affluent living conditions inevitably led the surrounding tribes to unite and want a piece of the pie after defeating Tuoba Liwei.

After Li Yan received the news that several surrounding tribes were moving a little strangely, Li Yan sent ten members of the Huaxia Self-Defense Force and a convoy of five modified trucks.

Ten members of the Chinese Self-Defense Force took with them five Power Triangles, as well as a large amount of military supplies carried in the van truck.

In this undefended grassland, these five van trucks reinforced with steel plates are undoubtedly five mobile strongholds.

In the mezzanine at the bottom of the carriage, there are two rows of steel pipes that have shrunk up, and the front ends of the steel pipes are polished to an extremely sharp point.

With the flip of a switch, these Changyu will stretch out from under the car and become a weapon for harvesting life under the powerful power of the truck.

The weapons and ammunition contained in the compartment, as well as the specially designed 360-degree steering firing compartment on the roof of the compartment, can turn the truck into a mobile fire output platform at any time.

The entire firing compartment was designed in a hemispherical shape, welded from steel sheets eight mm thick.

In addition to the shooting holes, the observation holes on all four sides are equipped with thick bulletproof glass, and the curved shape can effectively change the direction of the arrow, directing the destructive power of the bow and crossbow to other places, giving the shooter the greatest possible protection.

At the same time, several cameras installed around the vehicle can provide a full view of everything around the vehicle, so as to make the most advantageous combat choices.

And in order to cope with the extreme war situation, the inside of the tires of the trucks is completely filled with rubber, so that they almost become solid tires, and there is no need to worry about flat tires at all.

In the era when cold weapons such as war horses and bows and crossbows were mainly used, as long as there was enough fuel, such trucks were fearless in the face of thousands of horses and horses, even without ammunition.

Even with its own weight and strong power, it can also rush out of a bloody road.

Of course, all the blood on this bloody road belongs to others, and the force of this world has not yet reached the level where it can threaten such a "chariot".

It was the first time that such a chariot had appeared in a land outside of Huaxia, but anyone could feel the terrifying power it contained from the muffled sound of the engine and the slight vibration coming from the ground as it passed.

Tuobali was slightly frightened and prepared to welcome this convoy into Datong City, but was rejected by the Huaxia Self-Defense Force, because they wanted to complete the mission as soon as possible and return to Ping'an City as soon as possible.

Only in the safe city will they feel the comfort of life and the beauty of life.

Tuobali breathed a sigh of relief, the "Iron Monsters" he had seen before were obviously much smaller than these.

Moreover, more often than not, the people of Huaxia used them to transport supplies.

But in the eyes of Tuoba Liwei, they are already an invincible existence in land warfare.

And these "monsters", judging by the fact that they are covered with thick steel armor on all sides, are definitely a kind of "monsters" specially designed for combat.

With such a large body, in this vast grassland, even if it is crushed all the way, no one can stop its footsteps.

Inviting those people from Huaxia to enter the city was just out of courtesy, because he was very worried that these powerful "monsters" would stretch their waists in the not spacious city gate, and it was still a question whether the gate could withstand such an impact at that time.

Now that they choose to go around the city, they don't have to worry about these monsters accidentally collapsing the houses in the city.
