Fight,Primitive Man

After Chu Dong returned to the tribe, he did not continue to study more powerful black powder, but began to use saltpeter to coagulate ice.

Not only the three elements of gunpowder, saltpeter, were used to make ice, but charcoal was also used for other purposes.

Charcoal is the dark brown or black porous solid fuel left by incomplete combustion of wood or wood raw materials or pyrolysis under the condition of isolation from air. While maintaining the original structure of wood, a large amount of tar impure amorphous carbon remains in the pores.

Therefore, charcoal can be used as a component of black powder to burn rapidly.

But at the same time, charcoal is also the main raw material of activated carbon.

Activated carbon is mainly used as solid adsorbent, which can be used in chemical industry, medicine, environment, etc. it is used to adsorb substances with higher boiling point and critical temperature and organic substances with larger molecular weight. For an excellent doctor, Chu Dong is very familiar with activated carbon.

The reason why Chu Dong suddenly turned away from the black powder was that he had been able to calculate with Tianyan what kind of sensation the black powder would cause to the whole primitive society once it was widely used by ordinary people.

Especially for those people who have always been in a high position, once they find that the wide application of black powder will threaten their high position, there will be unexpected cruel suppression.

Just because his tribe became strong, he was under the eyes of the man temple. He wanted to kill himself again and again. It can be imagined that once Chu Dong armed the whole tribe to his teeth, it was not only the man temple that secretly attacked him with the help of other tribes, but also directly fought against him.

He could deduce the possibility of that kind of situation. Therefore, Chu Dong decided that before his strength was strong enough to attract and bear the crazy oppression of the inherent structure of this era, he would better develop steadily.

At least it should not be too far away from the track of this era.

At the same time, because of the understanding of kneading fire into ice, Chu Dong had another research direction.

When charcoal can be made into activated carbon to adsorb larger particles, why can't it store the storage force? The force changes completely, the shape becomes granular and stored in the activated carbon?

As soon as I got back to the lab, I thought about the possibility.

When many experts from the rock tribe, such as sun, bird wizard, axe, green leaf, came out from the closed state one after another, they heard that Chu Dong had been in the laboratory for more than ten sunsets.

It takes a long time for Chu Dong to study things, but this time it is the real night, and the time is the longest.

What makes people feel even more strange is that this time Chu Dong is very quiet in the laboratory. From the choking sound of going to deliver the meal regularly, people know that Chu Dong seems to be just meditating and so on, which is not the kind of heart stirring movement he used to make.

After more than ten days and nights, Chu Dong finally came out of the laboratory.

After getting the news, ah Hou is the first to run over, looking at Chu Dong with a full face of hope.

"Chu Dong, it took so long to study things this time. Did you come up with something good?"

"It does, but it has yet to be tested."

Ah Hou looks at Chu Dong's face full of self-confidence and smile, and his curiosity is even heavier. However, no matter how he asks, Chu Dong doesn't let go and tell ah Hou what good things he has invented.

Chu Dong asked: "ah Ho, have you been promoted?"

Ah Hou pulled out his chest and replied with pride: "of course, I'm a fierce beast warrior."

"That's good. Only when you are promoted in general can our tribe become more and more secure. "

Later, Yang, bird wizard and others who heard the news also came. Of course, they were just as curious as ah Hou about what new things Chu Dong had studied. But Chu Dong didn't tell them anything. He just said that after the success of the experiment in the future, everyone would know.

Chu Dong looked around. At this time, the weather had entered another autumn, and the plants began to wither.

"Originally, I wanted to hold a promotion and selection of barbarians this winter, but now I've changed my mind and I'm going to postpone it."

Chu Dong suddenly said this, others felt confused.

We need to know that the priority is to make the Panshi tribe more and more powerful. Why delay it?

"Chu Dong, why do you want to do this? Now some people are eyeing us. Maybe in the spring of next year, there will be similar attacks of animal tide. "

Chu Dong didn't answer Yang's question positively.

"Next, I'll go out with yeluo for a few days or a hundred days. During this period of time, I hope that you will unite sincerely and build our rock tribe into a rock like solid gold soup. "

"Do you want to go out again?"

"No, it's to find a match for yeluo.""Don't we have a lot of powerful brute bones in the warehouse of our tribe? Why do you want to be far away from the near? "

The question of axe is also the voice of everyone.

"Because yeluo's constitution is special, she needs more special brute bones, not how strong she is. Last time I went out for a whole year, didn't there be any major changes in our tribe? Believe you, this time there will be no problem, let alone as long as the smooth, more than ten days may come back

Chu Dong had already said so, so it was hard for them to say anything.

As a matter of fact, Chu Dong knew the contradiction between his own faction and the League faction as soon as he came back, but he never put forward any way to deal with it, because he knew that as long as he was there, the two factions would not really fight, let alone the inextricable links between them.

With the passage of time, the integration of the whole Panshi tribe will be more close. Although contradictions are inevitable, the same centripetal force is also constantly generated, but people do not seem to realize this.

Chu Dong suddenly decided to go out. Of course, he had his own consideration. For some things, he would not take them to the Presbyterian meeting of Panshi tribe. It was not a business, but a private matter.

"Don't worry, Chudong. We'll be fine. But, do you want to attend the winter gathering of Yunshan tribe? "

"Please take uncle niaowu to Yunshan tribe. Uncle niaowu, Yang, elder brother Liangqi and elder brother Lihuo, we'll have a chat in my cave later. "

People know that Chu Dong is to leave before the account of some things, but also understand that Chu Dong has made up his mind, so no longer ask what.
