The Pengcheng military camp has begun to take shape, and countless military and civilians are still busy working hard.

Lu Bu took Chen Gong away from the city early in the morning.

They seemed to have walked aimlessly for more than an hour.

As he got farther and farther away from Pengcheng, Chen Gong asked: "Wen Hou, where are we going?"

"It's here." Lu Bu stopped.

Looking around, he asked Chen Gong: "Is it difficult to control immigration to Pengcheng?"

"It's not just difficult to control." Chen Gong shook his head: "There are too many people, Pengcheng cannot accommodate them, and the supplies are also scarce. Almost every day, someone breaks the law. Although I try my best to restrain it, I have never achieved much results."

"It's because they are too idle, and Pengcheng is too poor." Lu Bu said: "The so-called poor mountains and rivers are out of troubled people. People have no money in their hands, and they always feel uneasy. The government has no way to make money, so they can only try their best to steal, rob and rob the house."

Chen Gong didn't say anything.

Lu Bu seemed to be saying that the unruly people were lawless, but in fact the topic was directed at the government.

Immigration has just arrived in Pengcheng, and many things have not yet begun.

He wanted to make a difference, but he couldn't start.

To control the place, you must have something to manage in the place!

"The military and civilians came with me to Pengcheng, so I can't make them suffer." Lu Bu said: "Only by enriching the people and strengthening the army, we can maintain long-term stability!"

"Wen Hou said that." Chen Gong responded.

Lu Bu pointed to a clearing area: "It's better to hit the wellhead in this place."

"Wen Hou saw that there was coal underneath?" Chen Gong asked.

"I don't have a perspective, how can I see it?" Lu Bu grinned: "I'm just a blind man catching a cat, and I'm just one who catches it."

Chen Gong was covered in black lines.

His casual finger means that countless civilians will open up the alleyway to the underground here.

Once the construction starts, it will cost a lot.

Not only will manpower and material resources be unlimited, but copper coins are consumed, but food and grass will also be a huge number.

If Lu Bu really guessed, it would be a joke!

Chen Gong's expression was very strange. Lu Bu laughed and pointed to the open space in front: "The office really thinks I'm a guess? I just saw the stones there and felt that there should be coal under it."

Looking at the stone Lu Bu pointed at, Chen Gong looked confused.

The stone was no different from what he had seen in the past. He really couldn't figure out where Lu Bu saw that there was coal underground.

"The stones are light black, and it can be seen that there is coal if it is not deep underground." Lu Bu said: "The coal in Xuzhou should be hundreds of steps deep. If we hadn't been able to detect it, I might not have chosen here."

Lu Bu turned his head and looked at the guard: "Tell General Zang to bring all the recruited personnel here."

Jumped off the horse and Lu Bu walked to the stone.

Chen Gong dismounted.

Squat down and picked up a stone, Lu Bu looked over and over again.

"Did Wen Hou discover something?" Chen Gong asked, who kept looking through the stone and thought he had seen something.

"Coal gangue." Lu Bu handed the stone to Chen Gong: "You can find this thing on the ground, but the coal is not deep."

"What are the next steps to mine coal? " Chen Gong asked.

"Promote it to the public, select the best forged steel, and create more powerful weapons for the soldiers." Lu Bu stood up: "There are many things that coal can do, and at present we can control only these."

Lu Bu took Chen Gong to patrol nearby, finding the most suitable place for excavation entrance.

They left Pengcheng and came here for more than an hour.

The guard returned and found Zang Ba, and then brought people here, which took at least three or four hours.

After all, it is impossible for everyone to ride a horse by Zang Ba.

Zang Ba brought the civil servants to the scene, and Lu Bu had already chosen the position to start the construction.

"Warm." Zang Ba came to Lu Bu's side.

Lu Bu glanced at the civilians he brought: "How many people are brought?"

"I didn't recruit too many people, I only brought more than 2,000 people." Zang Ba replied.

"How many stonemasons and carpenters are there?" Lu Bu asked, "Did the blacksmith bring them?"

"Everything is." Zang Ba replied: "It's just that there are very few craftsmen, especially blacksmiths, which are too difficult to find."

"Split the craftsmen separately." Lu Bu ordered: "The others are in groups of fifty people, and each group will choose the one who takes the lead."

He pointed to the selected place again: "Dig down from here, remember to dig out the slope, and people can walk down the hole."

"Wen Hou wants to dig tunnels?" Zang Ba asked in surprise.

"It can also be said." Lu Bu said: "There are two types of coal mines entering the well. One is a vertical shaft, which is to lift and lower the person down vertically. The other is an inclined shaft, where people can walk along the ramp. We do not have enough resources to open a vertical shaft, so we can only dig an inclined shaft to transport coal up."

The coal mine has not been built yet, so Chen Gong and Zang Ba are certainly not sure about the specific structure.

Lu Bu didn't know much about coal mines either.

He just recalled the structure of the mine based on what he had seen before.

The civilians who had no skills carried tools and digged up pits in the place designated by Lu Bu.

There are only 40 or 50 craftsmen with craftsmanship in total.

They were selected and stood in a pair.

Lu Bu came to them.

His eyes swept across everyone's face: "Carpenter, please stand up."

More than a dozen people stood up.

Their expression showed unconcealed panic.

"Are you carpenters?" Lu Bu looked at them.

"Yes!" More than a dozen people who stood up bent and responded.

"After I see the alley, I need you to support it with wood." Lu Bu asked, "Are you sure?"

"If it's not too deep, it should be fine." A carpenter replied: "If it's too deep, it's probably not easy. After all, the wood does not need iron tools. If it's too heavy, it will definitely be crushed."

During the Eastern Han Dynasty, the iron ore production was too small, and it was already difficult to use it to make weapons and farm tools. Of course, Lu Bu did not want too many iron tools to be used in the mines.

He asked the carpenter present: "What method can be used to make the wood as strong as iron?"

The carpenters looked at each other and no one answered.

Lu Bu asked again: "If the wood is soaked in tung oil, do you think it will be stronger?"

This sentence reminds the carpenter.

One of them replied: "In the past, we wanted the wood to be heavier and stronger, and we would paint tung oil. If we could soak it in tung oil, it would certainly be as hard as iron."

"Then soak the wood in tung oil." Lu Bu said: "It must not only be strong, but also tolerate decay. After all, wood soaked in tung oil is not as expensive as iron."

Iron tools are not of great value in two thousand years.

But in the late Eastern Han Dynasty, when the smelting industry was relatively backward, its value was far higher than that of tung oil.
