"The Classic of Mountains and Seas" calls coal "stone nirvana", and in the Wei and Jin Dynasties, coal was called "graphite" and "petroleum".

The term "coal" was first proposed in Li Shizhen's "Compendium of Materia Medica" in the Ming Dynasty.

Both of their opinions were correct. Song Gensheng didn't know about future generations, and Gu Qing didn't know about history, so they had a polite gentleman's dispute over how to call "coal".

The argument was not too intense, Gu Qing only felt pain in his hands.

Song Gensheng held his painful stomach and happily agreed with Gu Qing's decision. He felt from the bottom of his heart that the name "Coal" was simply a name given by God. It perfectly matched the dark and cold temperament of its body. If you refuse to use it, you will be punished by God.

.

"That's right, it's called coal." Song Gensheng squatted on the ground, looking a little aggrieved.

Gu Qing admired Song Gensheng's flexible character. He was a very easy-going person. If the two of them went to a restaurant, no matter who was treating the guests, he would definitely be the type of person who would take the initiative to hand over the menu to others and make the final decision. He was very sensible.

He just dug a pit about three feet deep and unexpectedly found coal. Gu Qing looked at the mountain where he was.

The mountain is not high, with an altitude of less than 100 feet. The mountain is densely wooded and bushy. It is no different from other mountains. However, they dug coal here. It is obvious that this is an open-pit coal-producing belt. At present,

I can't see much of the reserves, so I guess they aren't large. After all, the mountain isn't that big.

I don't know if it's good luck or not, but judging from Song Gensheng's attitude, people in the Tang Dynasty already knew what coal was, just by a different name, but they didn't seem to pay much attention to coal.

When Gu Qing first arrived, he was still in a state of feeling his way across the river. He was still cautiously trying to understand this strange world. Therefore, Gu Qing's current habit is to ask questions beforehand. If you ask more questions, you won't make a big mistake.

"Do you know what coal is used for?" Gu Qing asked tentatively.

"It's for burning." Song Gensheng looked at him strangely.

Good, at least you know what it is used for.

"Burn it for what?"

"The government often purchases it to make iron. If we farmers can get it, we can also use it, but it is not very useful. It is usually used for heating in winter and cooking, but it cannot be used in the house. I heard that in the early years

Several families were burning rocks and coal in their houses. The whole family died early the next morning. They were poisoned by charcoal and could not be saved. So we are still used to using firewood. Coal is not easy to get, but it is easy to get rid of it.

Human life is not a good thing."

Gu Qing asked doubtfully: "Why don't you come to make iron?"

Song Gensheng was surprised and said: "Are you crazy? Who dares to smelt iron privately? Being found out by the government is a serious crime of being exiled thousands of miles away. All the blacksmith shops in the city are run by the government."

Gu Qing understood. The Tang Dynasty knew that coal was used for burning, but its use was limited to making iron and heating. Moreover, the laws here were very strict and private people were not allowed to make iron casually. They were probably afraid of private iron making and casting of weapons.

This is interesting.

Gu Qing had little contact with coal in his previous life, but no matter how useless the material was, he at least knew some other uses of coal.

And if the uses that Gu Qing knows are put into practice, I am afraid that many people in the world will know how precious coal is. Then there may be many people fighting for this open-air coal mine. Bloodshed and desperate efforts are probably inevitable, and there may be

Bigger troubles, such as being coveted by the government...

Therefore, the secret of coal production here must be kept secret, and no one can know it.

Gu Qing cast a sinister glance at Song Gensheng and suddenly had a bold idea.

"Gensheng, what do you think of the scenery here?" Gu Qing asked pleasantly.

Song Gensheng looked around inexplicably and said, "You and I were born here since we were little. We are tired of looking at the mountains and water. Where did the scenery come from?"

Gu Qing stared affectionately at the big hole that had just been dug in front of him, and murmured: "It must be very comfortable to lie in it... Do you want to lie down in it and try it?"

"Why should I lie in there?" Song Gensheng looked puzzled.

Seeing Song Gensheng's confused look, Gu Qing sighed.

Forget it, he really couldn't bear to kill a cute and stupid guy, even though he was not very familiar with this guy.

"First fill up this hole, then go down the mountain, and you take me to catch fish." Gu Qing stood up with half-hearted interest.

The two filled the hole and reached the foot of the mountain an hour later.

When he was approaching the edge of the stone pool, Song Gensheng remembered something and suddenly grabbed Gu Qing in front of him. Gu Qing looked back at him and saw that his face was pale, his lips were trembling, and his expression was filled with shock and anger.

"Did you want to bury me on the mountain just now?" Song Gensheng asked in a trembling voice.

This child's reflex arc is so touching.

Gu Qing categorically denied: "I'm not! I didn't! Stop talking nonsense!"

"You, you, you, you actually want to bury me for that thing called coal?" Song Gensheng's body was as shaky as his three views.

Gu Qing subconsciously blurted out: "Because this coal is really important..."

Song Gensheng was shocked: "So you really want to silence me?!"

Gu Qing grabbed the back of Song Gensheng's neck and pushed him to the ground. Song Gensheng screamed, and the opera spirit possessed by Qiong Yao suddenly disappeared.

"I said, shut up and I'll beat you if you don't obey. Do you understand?"

Song Gensheng nodded obediently. At this time, he finally returned to reality and immediately thought that the person in front of him was no longer his little brother, but a rising new generation of village bully.

"Ahem, first of all, I'm not familiar with you..."

Song Gensheng's eyes were hurt: "We grew up together, are you not familiar with me?"

"Choujiro beat me up the day before yesterday. I fell down while running for my life and hit my head on a rock. I bled a lot, remember? The wound on my forehead has not healed yet."

Song Gensheng was a little confused, but he still nodded.

Gu Qing said solemnly: "The knock on my head was not just a trauma. In fact, I can't remember a lot of things, including a lot of memories about you. So, it's true that I don't know you very well.

.”

Song Gensheng looked at him suspiciously and reluctantly believed him.

"As for what happened just now, I suddenly lost my mind. For a moment, I really wanted to bury you. I'm sorry. I apologize to you first. In fact, the feng shui of that pit is really good. It gathers wind and stores energy, and it will bring prosperity to your descendants for generations to come.

You might as well think about it...Okay, forget it if you don't agree. In short, in my eyes, you are just a stranger now. I was greedy and wanted to kill people and seize treasures. It was my fault. Fortunately, it was just an idea.

I didn’t actually take any action, right?”

Song Gensheng glared.

Gu Qing patted his shoulder affectionately and said sternly: "So, the boat of our friendship has not capsized. Let us swing the oars and the boat hits the iceberg..."

Weird words often came out of Gu Qing's mouth. Song Gensheng didn't understand them, but he could understand some of the meaning.

At this moment, he was still angry and glared at Gu Qing: "Are you still going to bury me?"

"I won't bury it anymore. Our friendship is as solid as a rock. We will be good brothers for life."

Song Gensheng's IQ was on the line at this time, and he added a question: "You won't use other methods to silence me?"

Gu Qing paused for a moment, and the thought "Is this guy kicking his nose in the face" flashed through his mind. However, when his pause was seen in Song Gensheng's eyes, he suddenly felt frightened and angry.
