……

The witch sat on a rock, his legs curled up, and lightly put his feet on a polished bone to hold it in place.

His hands were held apart and he pressed the ends of the plank, pressed, lifted, pressed, and lifted again...... With his movements, the stone drill fixed on the drill pipe will rotate rapidly.

Then there is a 'boom~boom~' sound.

The place under the stone drill that needs to be drilled has now appeared a lot of bone foam, surrounding the stone drill.

While Wu was drilling with a hand-pressed drill, the strongest elder brother was also squatting aside, holding a bone fragment about the same thickness as Wu's feet in one hand, and a stone drill in the other, desperately drilling.

At the beginning, with his young strength, the speed of the senior brother drilling was faster than that of Wu.

But his high speed could not be maintained for long, less than two minutes, because he was tired, he had to slow down.

On the other hand, the old man, as at the beginning, generally maintained an unhurried speed, pressing down the plank one by one, looking calm and relaxed.

"Click."

There was a faint sound of something shattering, coming from the bone plate under the witch's feet, and at the same time, the rotating hand pressure drill was also stuck.

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

Wu carefully put away the hand pressure drill, picked up the bone plate under his feet and looked at it, a hole that was thick on the outside and thin on the inside, appeared on the bone plate.

Once you have this hole, you only need to hold a stone drill in your hand and rest for a while, and the hole in the bone is completely completed.

After Wu, whose face was only slightly red, put the hand pressure drill aside, the sweaty senior brother also stopped moving his hand, he put down the stone drill and bones in his hand, and moved his wrists and fingers, which had become sore and sore from rushing to drill.

Wu brought the bone plate that the senior brother had put down, and the hole in it was only about one-third the thickness of the bone plate.

This drilling competition ended with the old and frail Wu defeating the young and strong elder brother.

Moreover, the witch who drilled a hole can continue to drill at the same speed as before, and the senior brother, if he does not rest, his drilling speed will become slower and slower.

There is no harm if there is no comparison, and it cannot reflect the gap between the original drilling method and the hand-pressed drill made by Han Chengxin.

At this current rate, it is still very easy for a person to use a hand pressure drill to drill out six or seven bone holes in a day.

In other words, the drilling speed had to be increased by at least three times, and sure enough, it was necessary to develop new tools.

Wu, who experienced the benefits of the hand-pressed drill with his own hands, held the hand-pressed drill in one hand and the bone fragment that had been drilled out in the other, and gave a salute to Han Cheng with joy and sincerity, and praised in his mouth: "Son of God!" ”

The rest of the people who witnessed the wonder of the hand-pressed drill also followed the witch's movements, and saluted the Son of God together, shouting respectfully and excitedly: "Son of God! ”

Bowing down and praising the 'Son of God' every time they encounter magic has become the norm for the Qingque tribe.

Wu held a sacrifice again, and the items used for the sacrifice were the hand-pressed drill that Han Cheng had just made, and the bone fragment that had been drilled out of a hole with a hand-pressed drill.

In the past, the number of sacrifices held by the Qingque tribe was very small, from the spring flowers to another spring, it was already very good to be able to hold three or four times, but since the arrival of the Divine Son, the number of sacrifices held by Wu has begun to rise in a straight line.

Like recording things, Wu is also painful and happy, and sometimes, he also feels that frequent sacrifices will cause the gods to be dissatisfied, but if the gods do not tell the gods all kinds of miracles, Wu will feel uncomfortable.

So much so that now, every time Han Cheng comes up with something new, Wu has to go through such a tangled psychological process.

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

The manufacture of the hand-pressed drill is not complicated, when Han Cheng made it before, the lame and the black baby were watching from the side, they had already kept the process in mind, with the two of them, within two days, the Qingque tribe had five more hand-pressed drills.

The children in the tribe were far more interested in the new hand-pressed drill than the adults, and they always wanted to see the opportunity to experience the magical things created by the Divine Son, just like Han Cheng stood aside and looked at the bamboo craftsman with his eyes.

The appearance of the hand-pressed drill has greatly improved the speed of bone shovel manufacturing, but in just six or seven days, the Qingque tribe has produced fifteen or six more bone shovels!

Up to now, the storage capacity of the Qingque tribe's bone shovels has reached thirty-four!

In this way, after the beginning of spring, Han Chengcheng no longer has to worry about the lack of digging tools.

Even if there is a lot of work to dig after the beginning of spring, it is impossible for thirty-four bone shovels to be used at the same time, and the reason why Han Cheng made so many of them is to prepare more.

After all, the method of making this bone shovel is primitive, even if Han Cheng has already put a lot of effort into it, it cannot be as durable as the shovel of later generations, and in the process of digging, it is certain that there will be damage.

With a spare shovel, there is no chance of damage to the shovel that will affect your progress.

As for damaged bone shovels, they can be repaired when they are not working.

Of course, the use of hand pressure drills is not only in the manufacture of bone shovels, but also in the manufacture of many things in the future.

After a period of use, Han Cheng improved the hand pressure drill in response to the problems that occurred in the use process.

The improvement is in the rope.

Although the rope woven by rope grass is strong, it is not very wear-resistant, and in the process of continuous use, the rope is easy to break, and the improvement made by Han Cheng is to replace the rope woven with rope made of leather strips.

After the sacrifice, the people of the tribe were busy making hand-pressed drills, and Wu was not idle, recording them on the clay tablets in his inner cave.

Now the people who can enter the inner cave in normal times, in addition to Han Cheng and Senior Brother, there is one more person.

This person is not the leader of the original pig tribe, but a minor stone.

Because there are so many magical things made by the Divine Son, even with a relatively easy pottery board, the speed of writing has increased a lot, but Wu still can't keep up with the progress.

After thinking about it, Wu made the decision to choose the best stone in the tribe that had mastered the 'divine writing' and 'divine language' as his heir.

This can help him keep track of things and reduce Wu's workload, and secondly, Wu is not young and needs to start cultivating an heir.

In fact, at the beginning, Wu had the intention of taking Han Cheng as his heir and making Han Cheng the great and glorious Wu of the Qingque Tribe.

This kind of thinking of his has completely disappeared after Han Cheng broke the ice to get fish last winter.
