Douluo see you soon

Entropy also has little interest in saving the world, but this time he does not plan to be absent. Although he does not plan to personally enter the human beings in this world to complete the achievements of the world, he is still prepared to watch the whole process in case he misses something again this time.

important node.

The last time he missed a fragment of one of the top ten innate spiritual treasures, it already made him very distressed. No matter what good things there were this time, he was not going to miss them.

It’s just that this time it’s really boring. It seems like it’s really just using various means to promote the development of science and technology in accordance with the physical rules of this world, so that humans in this cold world can survive normally.

The first thing is to find a way to integrate into this world first. Soul transfer is easy, but you must first obtain a body in this world.

The two of them have strong strength. When using foreign bodies, they can be invulnerable to all laws in this world and are not affected by the laws of this world. But if they want to integrate into this world, it is best to have a

Belong to the identity of this world, so that human beings will have a sense of belonging and gather around them.

Cheng Ying chose a relatively simple method, which was cloning. After observing the humans in this world, he confirmed that among humans there are travelers who shuttle between different underground caves. They are usually powerful warriors.

With strong physical fitness and a certain amount of extraordinary strength, he can trek on the cold ice fields of the outside world and even reach the ground.

Although they can only survive in that harsh environment for a short period of time, it is travelers who are constantly passing on the technologies of various civilizations and tribes. This ensures that human beings can survive in this ice and snow without knowing technology.

Dating.

He also brought many plant seeds or steamed buns to different caves. In fact, those edible mushrooms and other things are not born that way, but have been transformed by humans.

That kind of thing means that it is something that has been improved by humans. Because of this, it can be so suitable as food.

There are other types of things like this in the world, but no travelers have brought those types of crops to this cave.

Cheng Ying used the genes of humans in this world to clone himself, creating a body for himself that could move around in this world and had a small amount of extraordinary power, allowing him to act as a traveler. Then he collected

Seeds of plants found in several nearby caves. Send them to this cave, and show as a traveler that these things can grow in caves and be used as food.

The people who can bring food in this era are basically good people. It is not easy to do this. To travel from different caves, it is very likely that you need to cross the cold surface or some relatively cold places.

Cave that is not easy to get through. This means that all travelers must risk their lives.

"I was injured during the trip and can only cultivate in your tribe. I hope you can provide food and water, and I will also provide you with the skills I have mastered." Cheng Ying's incarnation settled in front of him.

Among the tribes with the best conditions, this tribe is not the one with the largest population, but it has the best natural resources, and the surrounding metal minerals are quite rich.

It's just that they themselves don't know how to smelt these metal minerals.

"Next, I will pass on my knowledge. I hope you can carefully watch what I do. In this world, you can make weapons that are much more useful than the stones currently used."

Humans in this world are also active in the world rules of this world. So their stone tools are actually quite exquisite. Because they have learned to use magma, and after cooling the magma, they can make usable stone tools. The cooled magma is very useful to them.

It is a bit cold, and direct contact may cause frostbite. All you need to do at this time is to apply some liquid water on the palm of your hand. At this time, you will not give yourself frostbite by holding this stone tool, or put these stone tools on

Heating is carried out in the magma. However, the temperature is difficult to control. If the temperature is high, it will burn people. If the temperature is low, it will cause frostbite. People in this world are more sensitive to temperature than normal humans.

That's too high.

Therefore, the simplest solution is to apply a layer of liquid water. The water in this world is a very magical thing. Its temperature is extremely high for most substances in this world. But because of its own characteristics

It will not directly cause harm to humans. Therefore, after applying water on the body, most injuries caused by temperature can be avoided. So humans often regard liquid water as some kind of sacred object.

This is why tribes often have to obtain large amounts of liquid water, which is needed in all aspects of daily life.

"The next thing I want to teach you is metal smelting. I know that you can try to use the cooling of magma to make various stone tools before, and even the stone tools made are quite strong. But if the performance

Generally speaking, those things are still far behind compared to metal creations. If you want to survive in this world, you must learn how to make metals.

First of all, you need to find rocks that can withstand high temperatures, and then use them to build a container. In fact, you have also discovered that not all rocks will melt in magma. There are a small number of rocks that will not melt. They are

What we need is to use magma to hold them together so we can have a container of water that doesn't melt easily."

This chapter is not over yet, please click on the next page to continue reading! In this way, the people in the tribe built a large tank that will not be easily melted by liquid water, and has the ability to store a large amount of water. In the past, they could only

Store water in the form of ice cubes. When needed, temporarily melt the water with magma.

Now there is finally a way to store a large amount of liquid water, and liquid water is very precious to each of them. Many people have a dream, that is, they can sleep suspended in liquid water. This is almost

It was the ultimate enjoyment they could imagine.

It is difficult to find a temperature that can make them feel comfortable in nature. The temperature in most environments is either too hot or too cold for humans in this world. Surviving in this environment is quite tiring. It can even be said that it is too cold.

It's not an exaggeration to say it's quite painful. Therefore, few people can persevere in such an environment.

But if you soak in the water, the water will not cause any real harm to the human body. As long as the temperature of the water is adjusted to a temperature suitable for human survival, the person soaking in the water can feel the warmth and comfort.

The feeling is unforgettable for anyone who has experienced direct contact with water with their hands.

However, the only water tank in the tribe cannot be used by them in this way. It has other uses.

A large amount of copper ore, iron ore and other metal ores can be found around the tribe. After the water tank was built and enough water was poured into it, the traveler ordered the people of this world to collect various

Various minerals are piled next to the water tank.

"You may not have an intuitive judgment about temperature. After all, there are two temperature evaluation systems in this world. The temperature system of water and the temperature system of other substances fall into two categories. It is likely that it has caused your temperature sensing.

This is quite misleading. I can give you some guidance in this regard. Your liquid water has extremely high temperatures for most substances in nature. Even steel will melt in the presence of liquid water.

Of course, the temperature of liquid water is different, and the corresponding high temperatures are also different, so within the range of liquid water, you can try to process metals. These minerals are smashed and thrown into the liquid water. Then you find some more

You often use plants to burn for heating. Although the flames they burn are quite cold to you, the substances contained in them can turn these things that look like slag and have no strength at all into something quite solid and reliable.

Under normal circumstances, it is very difficult for you to process this kind of thing, but if it is in water, the difficulty is greatly reduced."

As the ore powder and the plant powder made into coke were put into the pool, a large number of bubbles appeared in the pool as if boiling at the same time. This was a reduction reaction at high temperature, and the oxygen inside the metal

In this incredible situation, it was restored, and as the substances in the water gradually settled, you could see liquid, sparkling metal flowing in the middle of a large amount of powder.

Cheng Ying put his hand into the water and touched the metal. The hot metal like lava came into contact with his hand, but there was no harm to each other.

These humans living in primitive societies did not feel strange when they saw this scene, because they have also tried it. As long as there is water isolation, even if they touch the magma directly, they will not be hurt. This is the rule of this world.

A special place.

Although these liquid metals are soft, they are still tougher than real water and feel more like plasticine. The processing of these metals underwater is much easier than in the blacksmith's warehouse.

"You can try in the future the effects of doping different metals with each other or other substances, and record these effects. I have only recorded one so far, which is to add a small amount of carbon to the metal.

Powder can make pure metal iron harder and more suitable as tools we use. Although they are usually too cold, as long as they are coated with some liquid water, they will not cause frostbite to us. Compared with

Stones after solidification of magma are more suitable for use as tools.

I will first demonstrate how to make a blade for everyone. With it, we can more easily harvest plants and hunt some animals deep in the cave."

I saw him put his hand into the water. After mixing a small amount of carbon powder into the metal, it was like ramen. He pulled the metal repeatedly, pulling the liquid metal into layers. As the temperature of the liquid water gradually increased,

As it decreases, the hardness of the metal begins to increase little by little, and the next step is to shape the metal like kneading plasticine.

The shape of the sickle's blade was gradually shaped, and it was quickly kneaded into the corresponding shape. After all this was done, he was taken out of the water and placed near the magma, letting it slowly

Cool down. During this process, both adults and children know not to touch the hot metal casually. When they are just out of the water, these metals will not burn people, but after being out of the water for a while

, they will cause substantial damage to people just like magma, so after they cool down, use the stone tools made before to keep them away from the magma little by little, and finally make them gradually become cold enough.

, can be held directly by hand.

Cheng Ying can skillfully master all the steps involved. As for people in this world, it definitely requires a considerable degree of training.

The sickle in front of you seems to be made of hundreds of sections of steel. The steps of folding it like ramen under water are folded and forged over and over again in the blacksmith shop. Even in the feudal period, steel of this level in the later period was

They are all considered to be of quite high quality and can be used as materials for swords and armor of soldiers or generals.

For people in this world, the conditions required are even simpler than those required for firing pottery. However, the physical rules of this world are so weird that a small number of primitive humans have not yet figured out how to smelt this kind of pottery.

Metal.

But these people are all human beings who have not just been refreshed and whose wisdom has been erased. With normal human intelligence, this kind of step is easy to memorize and learn.

After learning these steps, the nightmare of primitive humans began, trying to innovate on their own. At first, they tried to mix the copper and iron that were first practiced to see what kind of alloy they could make.

However, the result of the attempt was not very good. The alloy produced was slightly worse than the original pure state of the two metals. But this did not discourage them. Through similar methods, they made the alloy underwater.

Smelting. They found many, many metals. Each metal had its own properties, and the combinations among them were almost endless.

Occasionally, the right combination can often bring them unexpected and excellent materials. In this world, materials science is advancing by leaps and bounds in this primitive era. They may not be able to make even the simplest steam engine, but relying on

With this simple smelting method, materials science may even catch up with the second industrial revolution.
