I am a primitive

With the two previous walls as a reference, as long as they are willing to use their brains, it is not particularly difficult for Wu and the others to come up with such a solution, after all, they are not particularly primitive people.

Just when they thought they had a plan and were secretly proud that they had guessed what Shenzi would do next, what Shenzi did surprised them all.

Because after the low wall was built, the Son of God did not let people build a lower wall next to the low wall as they expected, but instead made people continue to increase the wall with the gate on the south.

Wu, senior brother, Shitou and others, you look at me, I look at you, and then look up at the low wall that is too high to climb after the shelf is removed. puzzled.

They really couldn't understand the behavior of the Son of God...

Of course, Han Cheng would not build a lower wall against the low wall, and so on, until people could climb up to the highest low wall.

In this way, at least three low walls need to be built, which is too much effort and unnecessary.

It is not difficult for him to solve this matter, he only needs to make some ladders.

For the Qingque tribe, who have a lot of wood, making ladders is not too difficult.

Han Cheng took two craftsmen, Lie and Hei Wa, to find some tall and straight trees with thick bowl mouths, and burned them to pieces, and cut them into pillars about [-] meters long. Ship it back to the Horde for later use.

Then cut some arm-thick tree segments ranging in length from one meter to seventy centimeters, and the next step is to make ladders.

Han Cheng picked two tree trunks of similar thickness, and asked Lie and Hei Wa to pick them out from the pile of wood and place them facing each other.

The two trunks are not placed in parallel, the distance between them is larger at one end and smaller at the other end, and the end with the larger distance is the root of the trunk, and the end with the smaller distance is the thinner end of the trunk.

The width of the bottom reached eighty centimeters, and the width of the top was only fifty.

After placing the two pillars, the next thing to do is to tie horizontal bars to the two pillars.

Lame, who often does knitting work, is very good at this matter. After Han Cheng demonstrated, he tied them every [-] centimeters, fast and firm.

Wu and the elder brothers, who had been struggling with how to climb the low wall, were very concerned about Han Cheng's actions, because they wanted to see what the Son of God wanted to do.

At the beginning, they were puzzled by Han Cheng's move to build the ladder. It wasn't until he started to tie the horizontal bars that Wu showed a thoughtful look.

When Han Cheng asked someone to carry the finished wooden ladder and leaned against the first section of the low wall, Wu's eyes sparkled. So far, he had completely understood what Han Cheng did.

When Han Cheng stepped on the ladder and climbed up the low wall first, the eldest brother and Shi Shi also showed a look of sudden understanding.

They stood under the fence, looked up at the Son of God standing on the low wall, and the thing that was leaning on the low wall, they didn't know what it was called, and were deeply impressed by the wisdom of the Son of God...

-------------Chapter Dividing Line---------------

After the first successful example, the subsequent ladders became easier to manufacture.

Considering the speed at which people in the tribe climbed the wall when the enemy attacked, Han Cheng felt that it was necessary to create more ladders.

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

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

The wooden ladders and bamboo ladders of later generations were made by digging out mortises on two pillars, and then smashing the crossbar into the mortises. The ladders made in this way are far from what Han Cheng imagined in terms of beauty and firmness. The poorly made ladders are comparable.

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

If you want to make a traditional wooden ladder, there is a difficulty that must be overcome. This difficulty is to make holes in the wood.

It is easier to make mortises in later generations, because there are sharp chisels specially used for cutting mortises.

Now, without suitable tools, Han Cheng could only frown and think hard in the face of this technical problem.

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

The hand pressure drill can be used to drill some small holes. Once the required hole is too big, the manual drill is also powerless.

This is not something that can be done with 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 drilling failed, Han Cheng turned his attention to the stone.

Since stone can be used to make 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 hard stone for making stone knives to make stone chisels according to his requirements.

The shape of the stone chisel is also simple, it is a round or flat long stone pillar, one end is knocked off little by little, and after a rough cutting edge is knocked out, it is placed on a big stone while sprinkling water while grinding it.

Sprinkling water during grinding is also reasonable. Of course, the most important thing is not to prevent dust and cool down, but that water can wash away the stone foam that has been ground, so that the stone used as a whetstone maintains friction.

The production of stone tools is a time-consuming task. The stone chisel is still the hand of the tribe who is better at making stone tools. It took three days to complete the work.

This wood is not that wood, this wood is an adult man from the Qingque tribe.

He used to live in the Qingque tribe. Before the people from the pig tribe joined, his personal force could rank five to seven in the Qingque tribe.

The reason why he is called Mu Mu is actually very simple, because he doesn't like to talk very much, and he always looks like Mu Mu.

Although the wood is wood, when it comes to building stone tools, the technology of wood is definitely second to none in the Qingque Tribe, and the same is true of the Pig Tribe who joined in later.

This may be related to his relatively wooden personality, and the manufacture of stone tools requires patience and continuous polishing.

So, in fact, everyone has their own shining points. The reason why they feel inferior in everything is because they only see the dazzling places of others, and they have not found something that suits their strengths.

Things are not absolute and can be converted in specific situations.

It's like wood that can't beat a fart compared to the three sticks. Letting him do business is naturally taken advantage of, but when he meets Shi Qi, he does things that others can't match.

"Dudududu!"

When other people in the Qingque tribe were busy raising the fence or harvesting grass, Han Cheng, the son of God, was also not idle. Tap the top of the stone chisel.

Following his knocking, saw chips were scooped up by the stone chisel on the big log on the ground.

The reason why the stone chisel is struck with wood instead of harder stone is that wood can protect the chisel from damage.

"toot toot"

Han Cheng put the stone chisel on the wooden pillar at an angle, and then struck it. It can be seen that a roughly square hole with a depth of two centimeters has appeared on the wooden pillar.

"Ah~"

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

The stone chisel still didn't work, it wasn't sharp enough, and it was fine at first, but as the depth of the chisel increased, the efficiency began to plummet.

This matter made Han Cheng feel melancholy, he just wanted to make some holes in the wood, why is it so difficult!
