"Shan Hai Jing" calls coal "Shi Nirvana", and coal was called "graphite" and "carbide" during the Wei and Jin Dynasties.

The title "coal" was first proposed in the "Compendium of Materia Medica" by Li Shizhen in the Ming Dynasty.

Both of them were right. Song Gensheng did not know the future generations and Gu Qing did not understand history, so they had a polite and gentleman battle over what to call "coal".

The debate was not too intense, Gu Qing only felt his hands hurt.

Song Gensheng covered his painful belly and happily agreed to Gu Qing's decision. From the bottom of his heart, he felt that the name "coal" was simply a god-given name, perfectly matched with its black and shiny cold temperament. If you refuse to use it, you will be guilty of it.

"Yes, it's called coal." Song Gensheng squatted on the ground, his expression a little aggrieved.

Gu Qing admires Song Gensheng's character of being able to bend but not stretched. This kind of person is very easy-going. If the two go to a restaurant, no matter who treats the guests, he will definitely take the initiative to hand over the menu to others to make decisions. He is very sensible.

But he dug a pit about three feet deep and accidentally dug coal. Gu Qing looked at the mountain where he was.

The mountain is not high and has an altitude of less than one hundred feet. The mountain is densely forested and bushes are everywhere, which is no different from other hills. But they just dug coal here. It is obvious that this is an open-pit coal mine belt. There is no way to see much reserves at present, and the reserves are estimated to be small. After all, this mountain is not big.

I don’t know if it’s good luck. Judging from Song Gensheng’s attitude, the people of the Tang Dynasty had already known what coal was, but they had different titles, but they didn’t seem to pay much attention to coal.

Gu Qing was just here, and he was still feeling the stones across the river. He was still exploring and understanding this strange world carefully, so Gu Qing’s current habit is to ask in advance, and ask more questions in the end he will not make a big mistake.

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

"It's used to burn it." Song Gensheng glanced at him strangely.

Very good, at least know the purpose.

"What are you doing?"

"The government often buys it for iron smelting. If we farmers can get it, it can also be used, but it is not very useful. It is usually used to keep warm in winter and cook rice, but it cannot be used in the house. I heard that in the early years, several families burned stones in the house... coal, and the next morning, the whole family died and was poisoned by charcoal. So we are still used to using firewood. Coal is difficult to make, and it is easy to kill people, and it is not a good thing."

Gu Qing asked in confusion: "Why don't you use to smel iron?"

Song Gensheng was surprised and said, "Are you crazy? Who among the people dares to smel iron privately? Being found out by the government is a serious crime of exile for thousands of miles. The blacksmith shops in the city are all handled by the government."

Gu Qing understood that the Tang Dynasty knew that coal was used to burn, but its function was limited to iron smelting and heating. Moreover, the laws here were very strict, and the people were not allowed to smelify iron at will. It was probably because they were afraid that the people would smelify iron to cast weapons.

This is interesting.

Gu Qing rarely had contact with coal in his previous life, but no matter how waste materials were, he at least knew some other uses of coal.

If the uses Gu Qing knew were practiced, I am afraid that many people in the world would know the preciousness of coal. At that time, there might be many people fighting for this open-air coal mine. It would be inevitable that they would bleed and fight to the death. Maybe there would be even greater trouble, such as being coveted by the government...

Therefore, the secret of coal production here must be kept tightly and cannot be let anyone know.

The sinful eyes glanced at Song Gensheng faintly, and Gu Qing suddenly had a bold idea.

"Gensheng, what do you think of the scenery here?" Gu Qing asked with a happy look.

Song Gensheng looked around for no reason and said, "You and I have been here since I was a child. I am tired of seeing mountains and waters. Where did the scenery come from?"

Gu Qing looked at the big hole just dug in front of him affectionately and murmured: "It must be very comfortable to lie inside... Do you want to lie in and try it?"

"Why should I lie inside?" Song Gensheng looked puzzled.

Looking at Song Gensheng's ignorant look, Gu Qing sighed.

Forget it, I really can't bear to attack a cute and silly guy, even though he is not very familiar with this guy.

"Fill this pit first, then go down the mountain, take me to catch fish." Gu Qingyi stood up in a daze.

The two of them filled the pit and it was already an hour later when they reached the foot of the mountain.

When he was about to reach the edge of the stone pond, Song Gensheng didn't know what he remembered, but suddenly grabbed Gu Qing in front of him. Gu Qing turned around and looked at him. Seeing his pale face, his lips were trembling, and his expression was full of shock and anger.

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

The child's reflex arc is so touching.

Gu Qing flatly denied: "I'm not! I don't! Don't talk nonsense!"

"You, you, you, want to bury me for the sake of 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's body was shocked: "So you really want to destroy my mouth?"

He grabbed Song Gensheng's back neck and Gu Qing pressed him to the ground. Song Gensheng screamed, and Qiong Yao's possessed dramatic spirit suddenly disappeared.

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

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

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

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

"Ding Erlang beat me the day before yesterday. I fell while running for my life. My head hit a stone and I dripped a lot of blood. Remember? The wound on my forehead has not yet disappeared."

Song Gensheng was a little confused, but nodded.

Gu Qing said seriously: "The moment I knocked my head was not just an external trauma. In fact, I don't remember many things, including my memory of you. So, it's actually true that I am not familiar with you."

Song Gensheng glanced at him suspiciously and reluctantly believed it.

"As for what happened just now, I suddenly became confused. For a moment, I really wanted to bury you. Sorry, I apologize to you first. In fact, the Feng Shui of that pit is really good. It gathers wind and hides energy, and it will bring prosperity to descendants for generations. You might as well think about it... OK, just forget it if you don't agree. In short, in my eyes, you are just a stranger now. I am greedy and have the intention to kill and grab treasure. It's not right. Fortunately, it's just an idea. I have no actual action, right?"

Song Gensheng glared.

Gu Qing patted his shoulder affectionately and said seriously: "So, the boat of our friendship did not overturn. Let us roar and the boat hit the iceberg..."

Weird words often popped up in Gu Qing's mouth. Song Gensheng didn't understand, but he could understand some meaning.

At this moment, he was still angry and glared at Gu Qing and said, "Do you still want to bury me?"

"We will not bury it anymore, our friendship is as solid as a rock, and we will be good brothers for life."

Song Gensheng's IQ was online at this time and he asked: "Will you use other methods to destroy my mouth?"

Gu Qing paused for a moment, and the thought of "Is this guy so arrogant?" flashed through his mind. As a result, his pause was shocked and angry when he saw Song Gensheng's eyes.
