After making a decision, Chu Nan ordered the clansmen to set up obstacles in the gap of five hundred meters, and let the fierce beasts run in, and then let some of the clansmen patrol the new territory within a radius of more than ten miles, kill all those fierce beasts, or drive them out, and relieve their worries.

This territory is inclined at a 30-degree angle, the highest point is nearly 1,000 zhang high, standing on the highest point, you can take in the scenery within a radius of dozens of miles, this is definitely a place to live and work in peace and contentment.

Except for two or three ferocious beasts, the area was a few docile herbivores, which were quickly cleaned up by the clansmen, and the next step was construction.

Chu Nan first asked people to find a wide place, made a fence, and raised the white sheep in captivity, which was of great use, and could not be despised lightly, and then caught some docile herbivores in the territory, raised them in captivity, and prepared to do experiments.

After arranging some simple things, the next thing to do is a very important thing, which is to deal with the wrath of the fire god, everything must revolve around this matter, centered on this matter, but other things cannot be completely put down.

"The current territory can be said to be on a cliff on three sides, one side is a slope on a big mountain, and the place connected to the ground is only about 500 meters, and these 500 meters are hidden dangers in the future, and a wall needs to be built to connect with the other three sides, but what is used to block it?"

Chu Nan knows that the best is of course cement, but this kind of thing is a bit unrealistic, with the current situation, it is impossible to make so much cement, the other is red bricks, the principle of firing red bricks Chu Nan knows, but there are too few people, and when the wrath of the fire god comes, he doesn't count in his heart, so he can only make two plans.

Bai Fumei stood quietly beside Chu Nan, this was one of her favorite things to do, because he found that the chief looked the best when he sat and thought, and he never got tired of looking at it, especially the chief's eyes, which always had a trace of confusion, but they were full of infinite wisdom, which was unpredictable.

"Fumei, you go and call a few elders such as Shi and the stump and the black mountain, I have something to discuss with them."

Bai Fumei agreed, and ran happily into the distance, in the distance was a hot labor scene, a large area was cleared out by the clansmen, leveled, and planned to build a place to live on it, and Chu Nan had already told the clansmen that he would build some brick houses for them to live in.

Although the clansmen didn't understand what the so-called brick house was, they knew from the other rare things brought by Chu Nan that the so-called brick house was definitely not simple, and they were full of expectations in their hearts, and they were full of enthusiasm when they worked.

Hearing Chu Nan tell them to have something to discuss, these people put down their work and hurried over with Bai Fumei.

"Do you know how long it will be until Vulcan's Wrath?" Chu Nan always felt unsteady in his heart, if he was given a year, he was confident that he would minimize the harm caused by the fire god's wrath, but if it was less than a year, he didn't know the bottom in his heart, whether he could lead his clan to avoid this disaster, this was what he was most worried about.

"Wait a minute, chief, I'll go get something." The stone said a word and left, and soon ran with a bundle of things.

When he got to the front of him, Chu Nan saw clearly, it turned out to be a bundle of hemp rope, each of which had a lot of knots tied on the hemp rope, and the whole bundle of hemp rope was tied with dense small knots, and the stone unfolded the hemp rope, and then counted them one by one, and finally pointed to the knots that he counted out and said: "A pimple represents one day, and it will take so many days, and the anger of the fire god will explode, at least there are so many days, or even more." ”

Chu Nan was secretly surprised and said, "This is the legendary knotted rope chronicle?" Too much trouble, right? If you encounter something, you still have to take it out and look at it again? It seems that after avoiding the wrath of the fire god, the construction of spiritual culture cannot be left behind, as long as there is knowledge, it will be much easier to communicate in the future. ”

Chu Nan followed the check when the stone was checked just now, a total of three hundred and nine, that is, there are still three hundred and nine days, although it is less than a year, it is less than two months, this world, the daily time is about the same as the earth, counting, there are still more than ten months.

"Well, that's enough, I'm going to give you something next, and remember that if we learn slowly, we may not be able to survive this Vulcan Fury." Chu Nan said solemnly.

Seeing Chu Nan so dignified and knowing that the stakes were high, Shi and the others all put away their smiling faces and said, "Please ask the chief to command, for our Tianhuo Clan to live, no matter what, we will do it, even if it is to die." ”

"I know you're not afraid of death, but sometimes death isn't the scariest thing, okay, let's get down to business." Knowing that there were still ten months left, Chu Nan breathed a sigh of relief, these hours were enough for him to teach his clan the method of burning red bricks, and he could also use red bricks to build a city wall to keep the so-called Infinite Beast tide out.

Chu Nan is still sure of how to fire red bricks, because when he was a child, he had seen the process of firing red bricks, and he had also seen the brick kiln for firing red bricks, from soil selection to making bricks, to air drying, how to load into the brick kiln, etc., a series of processes are very clear, so he is not afraid of failure, what he is afraid of is that these clansmen do not understand, and they repeatedly delay time, which will be troublesome.

Making bricks is manual work, and after handing over the previous procedures such as soil selection and brick making to the tree stump and Black Mountain, I watched them use stone tools to grind out a batch of wooden tools specially used to make bricks, and then led the stone and a few elders to the side.

"There is another requirement for firing red bricks, that is, it requires a high temperature of 800 to 1,000, ordinary wood burning, generally can reach seven or eight hundred degrees Celsius, compared to firing red bricks, the temperature is still too low, so you need to burn a lot of charcoal, charcoal can reach about 1,000 degrees Celsius in a closed brick kiln, which just meets the requirements."

Chu Nan said a lot of things crackling on the side, but several elders looked at him with a confused expression, not knowing what Chu Nan was talking about.

Chu Nan patted his head and said secretly: "Alas, I forgot again, although the earthen method of burning charcoal is simple, it is not clear to explain it to these people at all, so it is still necessary to demonstrate it, and it is not troublesome anyway." ”

Chu Nan asked people to find a relatively steep slope, and then dug a half-human-high, two-foot-wide hole on the slope, and dug a cave inside, and then asked people to find some wood, put the found wood in and light it, estimated that when the time was about the same, he found a stone, sealed the hole, and buried it with soil to isolate the connection between the cave and the outside.

After three experiments, he finally burned the charcoal of the highest quality, although everyone was black and gray, but they were all happy and laughed, Chu Nan handed over all these things to the stone to take care of, and he went to Bai Fumei, planning to have a good rest, he was really fucking tired.
