With the first successful example, the next ladder became easier to make.

Considering the speed at which the people of the tribe could climb the wall when the enemy attacked, Han Cheng felt that it was necessary to make more ladders to come out.

So within two days, five ladders were placed separately behind the low wall on the west side of the tribe's new high.

The more traditional ladders in later generations, such as wooden ladders and bamboo ladders, were not made in this way, and the main difference was in the installation of horizontal bars.

The wooden ladder and bamboo ladder of later generations were made by digging out the socket on the two pillars, and then smashing the crossbar into the socket, so that the ladder, whether it is beautiful or firm, is far from the simple ladder made by Han Cheng can be compared.

Considering that the wooden ladder is easy to be damaged by the wind and sun all year round, especially the situation that the rope that binds the horizontal bar is easy to deteriorate, after making a simple wooden ladder, Han Cheng wanted to make the traditional wooden ladder.

If you want to make a traditional wooden ladder, there is a difficulty that must be overcome, and this difficulty is to make an eye out of the wood.

In later generations, it was easier to make a hole because there were sharp chisels that were specially used to cut holes.

Now, without the right tools, in the face of this technical problem, Han Cheng could only frown and meditate.

Han Cheng thought of the hand-pressed drill that had been successfully made before, and after trying it many times, he had to shake his head and give up this method.

The hand pressure drill is used to drill some small holes, but once the eye is too big, the hand drill is also powerless.

It's not something that can be done by switching to a bigger drill bit.

Stone is a good thing, especially for primitive people and Han Cheng who can't refine metals such as copper and iron.

After the manual drill failed, Han Cheng turned his attention to the stone.

Since stone can be made into stone knives and stone axes, there is no reason why stone chisels cannot be made.

As soon as he said it, Han Cheng asked the people in the tribe to use the kind of hard stone used to make stone knives and make stone chisels according to his requirements.

The shape of the stone chisel is also simple, that is, a round or flat long stone pillar, knocked off little by little, knocking out a rough edge, and then placing it on a large stone while sprinkling water and grinding.

It makes sense to sprinkle water during grinding, and the most important thing is not to prevent dust and cool down, but to wash away the grinding stone foam and keep the grinding force of the stone as a whetstone.

The production of stone tools is a time-consuming thing, and this stone chisel is still the hand of the wood that is better at making stone tools in the tribe, and it takes three days to complete it.

This wood is not the other wood, this wood is an adult man in the Qingque tribe.

He was originally a person who lived in the Blue Sparrow Tribe, and before the people of the Pig Tribe joined, his personal strength was almost five to seven in the Green Sparrow Tribe.

The reason why he calls him wood is actually very simple, because he doesn't like to talk very much, and he always looks like a wood.

However, although wood is wood, when it comes to making stone tools, the technology of wood is definitely second to none in the Qingque tribe, and the pig tribe that joined later is also the same.

This may have something to do with the fact that he has a more wooden personality, and the manufacture of stone tools requires patience and continuous polishing.

Therefore, in fact, everyone has their own shining points, and the reason why they feel inferior everywhere is because they only see the dazzling points of others, and they have not found something suitable for them to show their strengths

Things are not absolute, and in a particular situation they can be converted.

It's like a piece of wood that can't beat a fart with three sticks, and if he is asked to make a deal, he will naturally be wronged, but when he meets the stone tool, he will do something that is difficult for others to achieve.

"Doot toot!"

While the rest of the Qingque tribe was busy raising the fence or harvesting the grass, Han Cheng, as the son of God, was also not idle, he was holding a stone chisel made of wood in one hand, and a piece of wood in the other hand was knocking on the top of the stone chisel.

As he struck, there were sawdust scraps on the large log on the ground that were shoveled up by the stone chisel.

The reason why the chisel was struck with wood instead of a harder stone was because the wood protected the chisel from damage.

"Doodoo"

Han Cheng placed the stone chisel diagonally on the wooden pillar, and then struck it, and it could be seen that a roughly square pit with a depth of two centimeters had appeared on this wooden pillar.

"Alas~"

Han Cheng tapped for a while, put down the stone chisel and the wooden stick in his hand, moved his somewhat tired hand, and sighed.

The stone chisel was still not sharp, it was not sharp enough, and it was okay at first, but as the depth of the hole increased, the efficiency began to plummet.

This incident made Han Cheng full of melancholy, he just wanted to make some holes in the wood, why was it so difficult!

When Mu saw Han Cheng throwing the stone chisel on the ground, his brows were furrowed, and his face was full of sadness, thinking that it was because Shenzi disliked the things he had polished, and he didn't speak, so he picked up the stone chisel that Han Cheng put on the ground, and then went to grind on the stone.

Han Cheng looked at the wood that was carefully polished with stone chisels, and at the same time sighed secretly with some warmth, this thing of stone, even if it is polished to the top, is not worth steel.

Except, of course, for a diamond that goes bankrupt.

Han Cheng looked at the wood and meditated, and chiseled it with a stone chisel all the way down, and finally he was able to chisel out the eye, but this was not what he wanted, because it took too long, and it was better to make a simple ladder tied with a rope directly.

As twilight fell, the Qingque tribe, which had been tired for a day, quieted down and the night was quiet, with snoring in the cave and a faint firelight flickering.

The shadow of the old primitive man who looked after the flames was cast on the mountain wall, and it looked particularly tall.

Han Cheng turned over and lay on his side and looked towards the cave, looking at this vague and quiet cave, which was very different from the daytime.

The movement of him turning over woke up Fu Jiang, who was lying at his feet, and Fu Jiang raised his head and looked around vigilantly, and when he saw that there was nothing unusual, he continued to lower his head and bury his nose under his tail, and continued his sweet dream.

Pregnant!

A thought suddenly appeared in his mind, which made his heart happy, and all the irritability was broken at once, and the whole person woke up.

Fire!

He looked at the faint dancing flame, his eyes burning.

Water and fire have the most effects, how can I forget it?!

He was so preoccupied with fire that he didn't fall asleep until late.

Han Cheng got up early the next morning, and after washing, he did a little exercise, and then began to carry out his eye-opening plan.

Han Cheng was bent on seeing that he had made it out, and it wasn't all for the ladder, just like the hand-pressed drill he had made before, it was also for laying the foundation for the future.

In ancient times, when iron nails were not overflowing, carpenters, bamboo craftsmen, etc. made all kinds of utensils, and the method used to connect them was Mao.

This seemingly inconspicuous hole actually has an extraordinary significance in the manufacture of utensils.
