Lu Xing found that he seemed to have asked the wrong question, so he changed his mind and said, "that's not what I mean... Well, do you have coal mines and oil here?"

"Coal mine? Oil? It's the first time I've heard of it. I can understand coal mine and mineral resources. As for oil, young Xia Lu, forgive my ignorance. I really don't know that stone can produce oil."

"Well... It's the kind of black thing that can burn."

Lu Xing explained: "coal, like charcoal, is black. The difference is that coal mines, like gold, silver, copper and iron, are dug out of underground mines. One characteristic of coal mines is that they are very black. As for the purpose and usage, they are similar to charcoal."

After thinking for a long time, young master he finally shook his head and said, "in the whole magical continent, there are dozens of countries in the West. Sad yuan has the most abundant and complete types of minerals. As long as there are some in the magical continent, sad yuan must have, and many. But I have never seen or even heard of such strange minerals."

No, Why not? Coal mine is an extremely common thing. In the picture that Lu Xing saw when he had a headache, people at that time discovered coal mine very early. Even if the intelligence quotient of people in Shenqi mainland is low, they don't know how to use coal, do they?

After thinking for a long time, Lu Xing couldn't think of an answer, so he had to ask again, "oil is also dark, but it's just a liquid. It's extremely flammable. As long as there is a little spark, it will burn, and the temperature is very high, which is extremely difficult to put out. Well, this thing also comes out of the ground. Have you heard of it?"

Not only young master he, but also the pregnant women around him were surprised and said, "what? Black liquid? Can it burn? It comes out of the ground? Brother, did you say smelly ditch? But it seems that it can't burn?"

be finished! From the surprised expressions of these people, Lu Xing knows the answer. It seems that this is a world without oil!

Lu Xing looked dignified and puzzled. How can there be no coal and oil in such a big God inspired mainland? Normally, these two things are not very difficult to see. Maybe it's normal that young master he and these pregnant women are used to living in dignity and don't know?

Thinking of this, Lu Xing's expression finally stretched a little and hurriedly said, "go and call those mining workers. I'll ask them."

Young master he said, "young Xia Lu, when it comes to mining, I'm just going to report to you. Although the quantity of various minerals you require is not much, it's also a lot. Although mining is a little troublesome, it's all OK. But young Xia Lu, there's a serious problem."

Lu Xing asked, "what's the problem? Just say it and I'll find a way."

Young master he said, "Sifang city is located in the center of sad yuan, far away from each mine. It's difficult to transport the ore back to Sifang city."

Lu Xingqi said strangely, "how did you deliver it before?"

Young master he said, "before we came, sad never transported minerals. Young Xia Lu, don't look at me like that. I really didn't lie to you."

The next pregnant woman came forward and said, "brother, there is a place to refine minerals near each mine cave. The weight difference between raw ore and refined minerals is not a bit."

Lu Xingming realized, "that's still ok?"

Young master he said reluctantly, "young Xia Lu, since we came to Sifang City, several countries around have Chen Bing's border. Everyone can see what they want. Now it's not safe to be sad. No one dares to refine minerals in the wild."

Lu Xing rubbed his head and said, "then you mine enough minerals first, and then I'll find a way slowly. Go."

Not long after going out, young master he returned to the backyard with an experienced miner. Lu Xing immediately described the appearance characteristics of coal mine and oil to the miners.

The miner stared wide and shook his head vigorously, indicating that he had worked all his life and had never heard of such a strange thing.

In the end, even Lu Xing began to wonder whether what he saw in his dream when he had a headache really existed? After thinking for a long time, I think it's wrong.

For example, fire guns, cars and mines were all he had seen when he had a headache and successfully made them. In this way, the things in the dream should be true.

So... This is really a world without oil!

Maybe there are too many gods, demons and ghosts in the world. The conditions do not allow them to be buried deep underground and become coal and oil.

Seeing Lu Xing's frown, the pregnant women below asked, "brother, why are you eager to find coal and oil?"

"Refining tools," Lu Xing replied.

"Refining? Refining with oil and coal? It's worthy of being a big brother. It turns out that in addition to using ground fire and heart fire, you can also use coal and oil refining. It's really a gain of insight."

"Go away and don't flatter there... Wait, what are you talking about? Use the earth fire and heart fire to refine the weapon?"

"Yes, don't you know?"

Lu Xing shook his head one after another. He really didn't know that. "San pan Jing" is indeed a wonderful book. It is so rich that it can be called an encyclopedia. Among them, there are many references to the way of refining utensils, but there is no fire to refine utensils.

It may be that the author of San pan Jing thinks that the problem of what fire is used for refining utensils is too low-level, and everyone should know it, so he ignores it when writing it. Lu Xing wiped his sweat in his heart and greeted the author again. What junk is it?

After sorting out Mu Leng's expression, Lu xingcai asked, "what is earth fire and heart fire?"

Pregnant women say: "The earth fire is the earth fire, the underground fire. Its temperature is very high. Whether it is used for refining utensils or medicine, it is completely enough. As for the heart fire, after the cultivation reaches the coagulation period, you can convert the spiritual power into heart fire in a short time. However, because the time is too short, the refining of utensils is not enough. Therefore, most people choose to use the earth fire when refining utensils. Only after the cultivation reaches the breaking period can you use it He will use fire to refine his weapon. "

After listening to this, Lu Xing suddenly realized that there was still this stress. But after thinking about it, no? When he was in Qingyu mountain that day, there were a large number of disciples in the blood training period, whether in the device refining group or the medicine refining group. Even in the coagulation deficiency period, there were few. As for the love breaking period? There were only a few love breaking periods in the whole Qingyu mountain?

Don't mention Qingyu mountain. Even if the whole east continent adds up, the love break period can be counted clearly. He has also been in the refining group, and he hasn't seen the ground fire?

After asking this question, the pregnant women smiled and said, "brother, they collected the fire. Although the ground fire is common, the surrounding temperature is too high, and even the practitioners in the condensation period have no blessing to suffer. Usually, the strong ones in the broken love period in the door collect the ground fire and put it in the door for everyone to refine their weapons."

"Is there such a saying?" Lu Xing found that he was really ignorant. It seems that one book of the three disk Sutra alone is not enough. There are many common sense things in the practice world.

It seems that you can't always nest in the mortal world. You must have more contact with the practice world.
