Everyone was busy farming, Li Ji was even busier, and he was busy fighting with Zhu Youneng.

In order to grasp the war reports in various places as soon as possible, Zhu Wen once vigorously built a post station. Duting Station is a post station in the capital, with 25 post houses under its jurisdiction.

At this time, a horse galloped through the dust, and two people sat immediately. One is Fuquan, and the other is Yiding.

The post boys are all skilled in equestrian skills, and they gallop like flying, so frightened that Fuquan clutches the horns of the post ding's clothes tightly, for fear of falling off the horse.

The rise of Li Jizheng and Zhu Youneng, the two gentlemen who are fighting, is coming.

"Your Majesty, Your Majesty!"

At this time, Li Ji was angry, there must be something big in the palace to annoy him, he was going to win this game, and he couldn't help but be angry: "What are you doing!"

At this time, Yi Ding and Fu Quan got off the horse, and Fu Quan panted with a copy of the song in his hand: "Your Majesty, Huangling Mountain is urgent!"

As soon as he heard about Huangling Mountain, Li Ji stood up suddenly: "Hurry up!"

Huangling Mountain, the place where Li Ji is most concerned at present, all his plans and steps are now bet there.

Fuquan rushed close and handed over the song, and Li Ji couldn't wait to open it to take a look.

I don't know if I don't see it, but I am surprised and delighted when I see it. In addition to the proper placement of these 10,000 people, the smelting of copper ore is progressing smoothly, and the first batch of copper ingots has been shipped to the capital. In the recital, the discovery of coal in Balziling was explained in detail, and Pan Da was stunned that he did not know what the coal reserves of Balziling were, so he did not dare to assert rashly. However, according to the investigation of experienced people, the reserves are amazing, even exceeding the copper reserves.

Li Jizhi looked at the blood surge, coal, or open-pit coal mine. In this day and age, even if you find large mineral deposits, you can only sigh because there are no tools to collect them.

But this open-pit coal mine is different, it is easy to mine, and the coal is bare or even only covered by topsoil. This discovery is worth more than a hundred copper mines, and coal is the foundation of industry.

With coal, you can smelt iron, smelt copper, make glass, and all kinds of industries, and even think that if the process allows, he can build a steam engine or a steam train.

Of course, this is just his fantasy, building a steam engine is not easy, and the engine alone is an unsolvable problem. But the discovery of coal mines was definitely a huge aid in iron smelting and glass making.

Coal mining in the Tang Dynasty was most prosperous in Chang'an and Taiyuan. In the fifth year of the opening of Tang Wenzong, when the Japanese scholars passed through Shanxi, they saw that Jinshan was piled up with mined coal everywhere, and it was sold in the states near and far. In the Song Dynasty, it was common to use coal to make iron. Coal mining is most prosperous in Hedong, Shaanxi, Jingdong and Jingxi Zhulu.

Marco Polo, an Italian, said: Black stone is burned all over China, and the price is cheaper than firewood. "Blackstone" is coal. The Song Dynasty has accumulated a wealth of geological knowledge of coal mines, calling coal seams "carbon veins" and outcrops "carbon seedlings".

"Heavenly Creations" once described in detail the methods of coal mining at that time: "Those who have been taking coal for a long time can distinguish the color from the soil surface, and then dig to a depth of five zhang Xu Fang to get coal." When I first saw the coal end, the poisonous gas was scorching. There are those who chisel the middle section of the giant bamboo, sharpen its end, and insert it into the charcoal, and its poisonous smoke penetrates through the bamboo, and people use the stool from under it to pick up. Or a well down, the charcoal is wide and horizontal, and it is wide and wide with it. It has a support plate on it to prevent the ear from collapsing. ”

The meaning is: "People who have a lot of experience in coal mining can judge whether there is coal underground from the soil conditions on the ground, and then dig down and dig to a depth of about five zhang to get coal." When coal seams appear, toxic gases can hurt people. One way is to chisel through the middle section of the big bamboo tube, sharpen the end of the bamboo tube, insert it into the coal seam, and the poisonous gas will be discharged through the bamboo tube, and people can go down to dig coal with a big hoe. When the coal seam is found to extend in all directions, people can dig through the roadway. The roadway should be supported with wooden planks to prevent collapse and injury to people. ”

Coal mining technology can be traced back to the late Neolithic sites, Shaanxi Fengxi, Baoji Rujiazhuang, Zhuyuangou Western Zhou tombs have found a large number of carved lacquer coal rings, jue and beads. Carved lacquer coal is located deep in the coal seam, and its use indicates that coal was already mined at that time. During the Warring States period, coal was called Shini.

However, these are mine diggings, and due to technical limitations, large-scale deep mine mining in ancient coal mining is not possible.

But Bald Ridge is different, this is an open-pit coal mine. Like the Huangling Mountain Copper Mine, it is inexhaustible.

Yique County is really a treasure of feng shui, fortunately it is close to the capital. Li knew that the discovery of copper and coal would be enough for him to change the world, but it would take time.

Li Ji was very excited, and he looked at Zhu Youneng with the song and laughed.

Zhu Youneng looked at Li Ji stupidly, and Brother Li was crazy again. Whenever Li Ji smiled with bad intentions, Zhu Youneng knew that there was no good thing, and he wanted to slip away: "Who is that, Han E, it's you, I'll help you grow corn."

Han E was holding a small notebook, and he was now more excited than anyone else. Having planted the land all his life, he knows the crops inside out. Although these things were things he had never heard of or seen, he could tell at a glance that they were definitely high-yielding crops.

He is now holding a notebook and has made a detailed record of how each crop was grown, soil moisture, and time. When Zhu Youneng called him, he was stunned for a moment.

As soon as Zhu Youneng stood up, he was stopped by Li Ji: "Brother Zhu, do you want to get rich?"

Li Ji has said this no less than eighty times, and Zhu You can take these three hundred hectares, and he hasn't seen a fart. planted these strange crops, and was scolded by my father. If these strange-shaped things grow out and are worthless and cannot be eaten, you will lose a lot of money.

"No, if Brother Li has a way to make a fortune, let's find someone else. I have already taken these three hundred acres. ”

Although Li Ji promised to pay the land rent, after all, he said it in vain. The ghost knows that when the time comes, he will not be able to pay the bill, he will be the emperor, and when the time comes, he will not give money, and Zhu Youneng will not be able to beat him for a long time.

"You have to think about it, you have to think if you don't want to." Sure enough, Li Ji played a scoundrel.

"No, I always think that these things you grow are unreliable." Zhu Youneng found a stone and sat down, but simply refused.

If you are rich, you are an uncle, and now Li Ji is an uncle: "Half a month later, I will rent you these 300 hectares of land, will you do it?"

"Fuck, whoever doesn't do it is a bastard!" After rubbing it, Zhu Youneng stood up: "Really give the ground rent in half a month?"

"I have a word!"

Li Ji was with him before he was the emperor, and he said that I would prove that he would give money 100%.

Zhu Youneng was overjoyed: "Say it, Brother Li, what do you want to do." Brother, I just smashed the pot and sold iron, and I also strongly supported the sale of houses and land. ”

"Good brother, I'm just letting you sell your land!"
