As night falls, according to the tradition of the tribe, we should hide in caves or houses and shivering. If wild beasts attack, we can only pray that the warriors can defeat the wild beasts and fight against them at night, many people will die.

After a busy day, after dinner, I was about to rest, but I discovered something fearful. Some strange things were actually glowing in the room. I promised the gods that this was not fire, but a miracle. There was also a sun in the room emitting light.

I was arranged in a room to smash the stones, and the rest were responsible for collecting the stones. Not far away, there was a woman sewing the animal skin.

There must be gods and immortals here, and I finally know why my tribe cannot defeat others. This place with gods’ blessings is really great to serve gods.

Li Zhen didn't know what these primitive people were thinking, but the lights turned on and work at night was entirely because he was shocked by these primitive people. Primitive people were very easy to fool. As long as something they could not understand, they would immediately be regarded as a miracle.

A tribe with more than 200 people, plus Li Zhen and others only had less than 300 people, devouring a tribe of five or six hundred people. Once a problem arises, it will have a great impact on Li Zhen and others.

So after a simple discussion, everyone decided to simply intimidate the primitive people, so that night, all the rooms equipped with light bulbs started working overtime all night. This was the first time that Li Zhen’s tribe worked at night.

At first, Li Zhen was worried that he could not scare these primitive people, but when these primitive people saw the light bulbs that were lit at night, they immediately knelt down and began to worship them. The primitive people of the tribe before Li Zhen looked at the group of local buns in front of him with a look of unscathed expression, and had never seen the world.

The work efficiency is very low at night. Most of the work is to process the ore, wait for the blast furnace to smelify iron tomorrow, and also to simply process the animal skins to make clothes that can be roughly worn.

Primitive people have no sense of shame. They can work by wearing animal skins, wearing grass skirts, and exposing their breasts. However, people from Earth don’t wear clothes, especially a few women. Although they can’t make clothes on Earth, after they come to Mingqixing, they start various DIYs. The animal skins can be made into various styles for them. It is said that Earth is preparing to hold a Mingqixing style clothing exhibition this year at Milan Fashion Week.

"Li Zhen, I found something good!" As soon as he got up, Professor Lu found him panting, with sweat on his head, and the two students behind him pinched their waists.

"Young people today are really not physically strong! Look at you, you can be so tired after walking a little bit!" Professor Lu cursed his students a few times, then took out a piece of golden metal from his animal skin backpack and handed it to Li Zhen.

Li Zhen held the metal in his hand and looked at it. The golden part looked familiar, and some looked like gold. He couldn't help but speak: "Gold mine?"

"It's a gold mine. When you cross this mountain, there's a gold mine on the back, but I guess it's a silver mine, accompanied by gold mine!"

Li Zhen looked at the gold with great interest: "Professor Lu, gold mines are useless, now you can't buy anything if you have gold!"

Before he finished speaking, the stick in Professor Lu hit Li Zhen directly: "If you don't learn, you will not learn, you will not learn, if you are on the earth, I will definitely beat you! Do you think gold is money?"

Li Zhen nodded. Can gold be circulated as currency? He has not heard of what gold has. Most people on earth nodded the same. No one knows what gold has.

Professor Lu was so angry that he was very angry by Li Zhen: "You kid, you still want to escape. Do you know how important gold is in communication and aerospace? Without gold, do you think that spacecraft can be built with iron? Do you build rockets?"

Li Zhen secretly complained in his heart: "But gold can be bought with Rockets!"

"Professor Lu, then tell me, what is the use of gold?" Li Zhen looked humble and studious. There was no way. Although he was in danger of the earth, he really didn't dare to show off in front of these old scholars. If there was an old man in the family, he could only endure it. He was scolded and endured it. Moreover, these professors scolded him for his own good.

"The metal of gold has extremely high corrosion resistance and stability, good electrical conductivity and thermal conductivity. Moreover, the atomic nucleus of gold has a large effective cross-section that captures neutrons and reflects nearly 100% of infrared rays. If gold is added to other metals, other metals can have good processability and are very easy to process into gold foil, micron gold wire and gold powder, and are easy to dissolve and weld, and can also produce superconductors and organic gold!"

"In addition, gold has a very good ductility. One or two pure gold can be hammered into one thousandth of a millimeter of gold leaves, can be pasted with an area of ​​nine square meters, and has little volatileness. If you tell you something else, you don't understand. Anyway, you need gold if you want to build a rocket or a spacecraft or a computer. Do you know!"

Professor Lu said a lot. Although Li Zhen didn't know what he was talking about, he always felt very powerful and nodded in an uncertain way: "Okay, Professor Lu, I know Professor Lu!"

Professor Lu looked at Li Zhen's appearance and knew that this guy probably didn't understand it. He waved his hand: "Forget it, I don't expect you to understand it. Anyway, gold mines are very important, but our technology is not available. I will take people to mine some later. I will go there to see if I can find silver mines. If there is silver mine, it will be of some use to us now!"

"good!"

Without hesitation, Li Zhen went to find a few primitive people, followed Professor Lu's butt, and ran towards the place where the gold mine was discovered. Gold mine, let alone gold mine on earth, even gold, Li Zhen had only seen it in others, and he had never bought it.

However, what Li Zhen is curious now is that the resource reserves of this Mingqixing are very amazing. You can find rich mineral resources by walking around casually. The mountain in front of his tribe's residence is completely a mine composed of iron ore. According to the mineral distribution, there is no concomitant relationship between iron and gold and silver, and it should not be so close.
