Chi~Chi~

Chi~Chi~

Chi~Chi~

…

The witch sat on the stone, curled up his legs, and placed his feet lightly on a piece of polished bone to fix the bone and prevent it from moving.

He held the two ends of the hand drill board with his hands separately, pressing and lifting, pressing again, and lifting again... As he moved, the stone drill fixed on the drill rod would rotate rapidly.

Then a 'chi~chi~' sound was made.

A lot of bone foam has now appeared where the hole needs to be drilled under the stone drill, surrounding the stone drill.

While Wu was drilling with a hand drill, the strongest eldest brother squatted beside him, holding a piece of bone about the same thickness as the one under Wu's feet in one hand and a stone drill in the other, drilling desperately.

At the beginning, relying on his youth and strength, the eldest brother drilled the hole faster than Wu.

But he couldn't maintain this high speed for too long. In less than two minutes, he had to slow down because of fatigue.

On the other hand, Wu, the old man, just like in the beginning, maintained a steady pace, pressing the wooden board down one by one, appearing to be calm and composed.

“Crack.”

There was a slight sound of something breaking coming from the bone plate under the witch's feet. At the same time, the rotating hand drill was stuck.

This is a sign that the bone plate has been drilled through.

Wu carefully put away the hand drill and picked up the bone plate under his feet to take a look. A hole that was thick on the outside and thin on the inside appeared on the bone plate.

After making this hole, you just need to hold a stone drill in your hand and do some adjustments, and the hole on the bone will be completely completed.

After the witch, whose face was only slightly red, put the hand drill aside, the eldest brother, who was sweating profusely, also stopped his actions. He put down the stone drill and the bone in his hand, and moved his wrists and fingers that had become painful and sore from the rush of drilling.

The witch took the bone plate that the eldest brother had put down. The hole on it was only drilled into about one-third of the thickness of the bone plate.

The drilling competition ended with the old and weak Wu defeating the young and strong senior brother.

Moreover, the witch who has drilled a hole can continue drilling at the same speed as before, but if the eldest brother does not take a rest, his drilling speed will become slower and slower.

There is no harm without comparison, and the gap between the original drilling method and the hand drill invented by Han Chengxin cannot be reflected.

At the current speed, it is very easy for one person to drill six or seven bone holes in a day using a hand drill.

In other words, the drilling speed must be increased by at least three times. Indeed, it is still necessary to develop new tools.

Wu, who had experienced the benefits of the hand-operated drill, held the hand-operated drill in one hand and the bone fragment with the other. He bowed to Han Cheng with sincere admiration and praised him, "Son of God!"

The others who had witnessed the miracle of the hand-operated drill followed the witch's movements and bowed to the Son of God, shouting respectfully and excitedly, "Son of God!"

Bowing and chanting "Son of God" whenever encountering miracles has become the norm for the Qingque tribe.

The witch held another sacrifice, and the items used for the sacrifice were the hand drill that Han Cheng had just made, and the bone piece with a hole drilled in it.

Before, the Qingque tribe held sacrifices very rarely. From one spring to another, it was already very good if they could hold sacrifices three or four times. But since the arrival of the Son of God, the number of sacrifices held by the witch began to rise sharply.

Just like recording things, Wu also felt pain and joy. Sometimes, he felt that frequent sacrifices would cause dissatisfaction among the gods. However, if he did not tell the gods about the various miracles created by the Son of God, Wu would feel uncomfortable.

To the extent that until now, every time Han Cheng comes up with something new, Wu has to go through this same tangled psychological process.

After the sacrifice, the manufacture of hand drills began in large quantities.

The manufacture of a hand drill is not complicated. When Han Cheng was making it before, Bo and Heiwa were watching on the side. They had already memorized the process. With the two of them there, within two days, the Qingque tribe had five more hand drills.

The children in the tribe are much more interested in the new hand drill than the adults. They are always looking for an opportunity to experience with their own hands the magical thing created by the Son of God, just like Han Cheng standing by and staring at the bamboo craftsman.

The emergence of the hand drill greatly increased the speed of bone shovel manufacturing. In just six or seven days, the Qingque tribe had fifteen or sixteen more bone shovels!

By now, the Green Bird Tribe’s storage capacity of bone shovels has reached thirty-four!

In this way, when spring comes, Han Cheng will no longer have to worry about the lack of digging tools.

Even though the workload of digging is huge after the spring, it is impossible for all thirty-four bone shovels to be used at the same time. The reason why Han Cheng made so many of them was to prepare more.

After all, the manufacturing method of this bone shovel is primitive. Even if Han Cheng has put a lot of thought into it, it can't be as durable as the iron shovels of later generations. It is bound to be damaged during the digging process.

With a spare bone shovel, the progress will not be affected by damage to the bone shovel.

As for the damaged bone shovel, you can wait until you are not working to repair it.

Of course, the hand drill is not only used in the manufacture of bone shovels, but can also be used in the manufacture of many things in the future.

After using it for a period of time, Han Cheng made improvements to the hand drill to address problems that occurred during use.

The improvement is the rope.

Although the rope woven from rope grass is strong, it is not very wear-resistant. The rope is easy to break during continuous use. The improvement Han Cheng made was to replace the rope woven from rope grass with a rope made of twisted leather strips.

After the sacrifice, everyone in the tribe was busy making hand drills, and the witch was also not idle, recording all of this on the pottery plate in his inner cave.

Now, in addition to Han Cheng and the eldest senior brother, there is one more person who can enter the inner cave at ordinary times.

This person was not Shang, the leader of the original pig tribe, but the underage Shitou.

Because the Son of God created so many magical things, even with a more user-friendly pottery tablet, the writing speed increased a lot, but the witch still couldn't keep up with the progress.

After thinking about it, the witch decided to choose the best stone that mastered the "divine characters" and "divine language" in the tribe as the heir.

This would help him record things and reduce Wu's workload. Secondly, Wu is getting old and needs to start training a successor.

In fact, at the beginning, Wu wanted to make Han Cheng his successor and make Han Cheng the great and glorious witch of the Qingque tribe.

This idea of ​​his had completely disappeared after Han Cheng broke the ice to catch fish last winter.
