When he saw the coal, Li Zhi came near and picked up the coal. His hands trembled with excitement.

"Where did you get these things?"

The woman was obviously shocked by Li Zhi's manner: "what's the matter, little brother?"

Li Zhifang found that he was a little too excited. He cleared his throat and said to the woman, "sister-in-law, it's only the first time I've seen such things. I didn't expect that I could cook."

After listening to Li Zhi's words, the woman said to him, "Oh, it's the first time I've seen you, little brother. No wonder! Ten years ago, we found this thing in a cave. We accidentally found that it can be used for cooking. Our small village also uses it for cooking. It's just that mining is troublesome, so the annual amount is not large, but it's enough for the whole village. "

Li Zhi's heart leaps wildly. With coal, can't everything develop rapidly?

Coal can be used to make steam engine. If the steam age has come, will the electric energy age be far behind?

Thinking of this, Li Zhi's eyes narrowed. I don't know how the gods in the sky are fighting with my current technology?

At this time, a systematic prompt appeared in Li Zhi's mind: "congratulations to the host for discovering the coal of Fengshen world. 10 points will be awarded."

The sound of the system suddenly appeared, which made Li Zhi very happy. Unexpectedly, he was rewarded with points when he found coal.

At this time, when the man came back from the outside, he carried a big bucket of water in his hand and gave Li Zhipeng and Xuan a few bowls of water. After Li Zhi had a drink, he found that the water was very sweet, a bit like the mineral water that later generations had drunk.

Then Li Zhi said, "brother, I don't know what are the black plants used for burning in the outer room?"

The man touched the back of his head and said to Li Zhi, "I don't know exactly what it is, but ten years ago our village used it as firewood, and it's much cleaner than firewood. We don't know what it's called. Anyway, it's very comfortable to use."

After he said this, Li Zhi said to the man, "can you show me where this thing is mined?"

The host was obviously more hospitable. He said to Li Zhi, "OK, it's not far from the mountain."

After listening to his words, Li Zhi said to Peng Xuan and Kong Xuan, "two good brothers, come and have a look with me."

Peng Xuan and Kong Xuan didn't know what those things were, but seeing Li Zhi excited, they knew that they were very important to Li Zhi.

When he came to the back mountain, Li Zhicai found out where the coal mine was.

This is a low mountain. At the foot of the mountain is a cave. When walking along the cave, the man wanted to light a torch.

Li Zhi's heart is beating wildly, which means that he is not afraid of death in this era.

If it's post era, who dares to use open fire in the mine? It's going to explode and go to heaven

But looking at people familiar with the appearance should not be a problem.

After walking down for about seven or eight meters, Li Zhi found the coal mine mentioned by this group of people. As expected, he found the existence of the coal mine layer in the underground soil layer. After Li Zhi saw the coal mine layer, he was very happy. After he wrote down the place, Li Zhi said goodbye to the man and left some coins as a token of thanks, but the man said nothing.
