Gongsun Xu has always had an idea that it is necessary for him to let his craftsmen have good enough living conditions, only in this way can they have motivation, can they better work for him, and can research more advanced scientific and technological productivity.

Science and technology are the primary productive forces, and only when science and technology go up will there be faster progress.

As long as he can research out good things, when the time comes, he is deciding whether to mass produce them, considering whether to make money or as a means to press the bottom of the box.

It's like the trebuchet in his hand now, except for the ten crosses sent to Lao Tzu Gongsun Xu, the others have been kept secret, and he doesn't want the trebuchet to spread too quickly.

This kind of trebuchet Gongsun Xu wants to keep it secret, because Gongsun Xu has not yet come up with an attack machine that is more powerful than the current trebuchet, and if other forces get the method of making the trebuchet, then he will lose more than he gains.

Now Gongsun Xu only has a city in Xiangping, and the population under his command is only 300,000, once this trebuchet flows outside, there are many other forces, as long as there is a scheming to see this trebuchet, then it will inevitably be produced in large quantities, if the Han Dynasty collapses, and the princes of all parties compete for hegemony, he will suffer at that time, and there will be no force to deter the enemy.

Gongsun Xu felt that this kind of trebuchet had to wait for him to master the more advanced types before he would consider disposing of the trebuchets in his hands that were about to be obsolete.

And at this price, Gongsun Xu will also ask for a sum of money.

Gongsun Xu felt that he had to be ahead of the others step by step, so that he could successfully rise in the late Han Dynasty.

He is a person who has traveled through the afterlife, and the foreknowledge is inevitable, and everything that needs to be done must be done first, just like the coal he is hoarding now.

Coal is needed for brick burning and steelmaking, and it is a large amount of coal, which is something that Gongsun Xu must take into account.

Coal has long been used in steelmaking in the Han Dynasty, but what! In the Han Dynasty, not many coal mines were found, and they were quite laborious to mine.

The Youzhou area is sparsely populated, and there is no coal found, and the coal used in the steelmaking plant on this side of Longshou Mountain is pulled from the Central Plains, which virtually increases the cost of steelmaking.

Gongsun Xu is different from later generations, he knows best in his heart that there are several large coal mines in Liaoyang, that is to say, as long as he can find such a large mining area, he will not have to worry about the use of coal in the future.

After Gongsun Xu became the master of Xiangping, Gongsun Xu sent some people who knew coal to look for minerals everywhere, especially in the area of Xiangping Xima Peak, where there were more people.

In later generations, Gongsun Xu knew that in Liaoyang, that is, on the side of Xiangping City, there were several coal mines of considerable scale.

These coal mines are all in the area of Xima Peak, but Gongsun Xu did not know where Xima Peak was in the late Han Dynasty and what was the difference between the location of Xima Peak and the location of later generations.

The place name of Xima Peak should be a place name that only began to appear after the Tang and Song dynasties, and at this time, that kind of place should be quite a desolate and barren land.

Gongsun Xu just knew that this Ximafeng coal mine was not very far from Liaoyang, about dozens of miles away, if he was not mistaken, the coal mine was probably on the north bank of the Taizi River, northeast of Liaoyang.

I don't know if Gongsun Xu was lucky or if Gongsun Xu sent more people, that is, after more than ten days of hard work, the people sent by Gongsun Xu got the news.

When Gongsun Xu heard the news that the coal mine had been found, he immediately gathered more than 1,000 soldiers under his command and drove all the way to the wasteland with thousands of young men from Xiangping City.

Coal mines are the top priority of future development, and in order to better control the coal mines over there, Gongsun Xu asked all the trees along the road to be cut down by him, and while marching, he began to pave the road in the way of paving the road in the Han Dynasty.

However, Gongsun's way of continuing to build this road is different from the way other officials build the road, after paving a distance of more than ten meters with that kind of blue stone on a section of the road, the rest of the road is cushioned with soil, and then those leather-covered stones are constantly smashed by people until the road surface is very compact.

Gongsun Xu knew very well in his heart that it was already quite a luxury for the Han Dynasty to be able to pave such a road as him.

If he didn't occupy Xiangping City now, there were many young people in Xiangping City, and he would not only give food to those young people who went to build roads, but also give those young people a certain amount of money as wages.

It is for such a reason, that is, in less than a month, the road from Xiangping to the coal mine on the side of Ximafeng has been paved.

The people who opened the mines were all loyal soldiers under Zhang Chun, and they were directly turned into slaves by Gongsun Xu after surrendering.

These people have this old master in their hearts, and they don't know when they will give birth to some rights and wrongs, and they still feel unbearable to kill all of Gongsun Xu, just as a miner who opens a mine, when they are tired and when they will pull them down.

After the coal produced on the side of Ximafeng is sent to the south bank of the river by manual picking, it will be loaded on the south bank of the river and pulled directly to a freight yard outside Xiangping City.

Gongsun Xu, the extermination of the bandits in Longshou Mountain, had already mentioned it on the agenda, but he always felt that he had just entered Xiangping City, and there was no time for him to suppress the bandits in terms of army training or other aspects.

This time, the thieves of Longshou Mountain are so ignorant, he must destroy all the thieves of Longshou Mountain and firmly hold Longshou Mountain in his hands.

Gongsun Xu wanted to build a new city on this side of Longshou Mountain, and spread out the things he thought about step by step.

More than ten miles of Longshou Mountain was in full swing, and Liu Xing couldn't sit still.

After Liu Xing made a detailed report to his subordinates and sent a team of thousands of people to Longshou Mountain in Xiangping City, his heart has been hanging in the air, and he always has a worry that Gongsun Xu is looking for him to take revenge.

Although Longshou Mountain is easy to defend and difficult to attack, he is facing Gongsun Xu, who attacked Xiangping in a few days, and he can't help but think about the fact that Longshou Mountain was defeated by Gongsun Xu.

It was Qiu Mao and Liu Wu who were put under house arrest by Liu Xing, although Liu Xing did not clean up their group, but no matter how you look at these people, there are problems.

It wasn't until several of the henchmen sent into Xiangping City returned that it was confirmed that Gongsun Xu was not dispatching the army of Xiangping City at this time, but the young Zhuang sent to Longshou Mountain to restore the steelmaking furnace.

Not only did they not hear any bad news about the investigation of the Hou family in Xiangping City, but they also heard several good news.
