"Wu, don't move, cut your hand."

Seeing that Wu was about to imitate him and put his fingers on the blade to scratch it, Han Cheng quickly spoke out to stop him.

In later generations, he mowed grass a lot. At the beginning, he asked adults to sharpen his sickles, and later he started to sharpen them himself. He was able to master the skill of testing whether the sickles were sharp by hand.

But Wu was not like that. The sharpest thing he had ever touched was a bone knife, and it was difficult for him to determine the strength of the knife by testing it with his hands.

Now he has sharpened this newly made iron knife. Although it is not as sharp and wear-resistant as a steel knife, it can still cut your hands if you are not careful.

After hearing Han Cheng's words, Wu withdrew his hand.

He kept looking at the iron knife which looked very different from the bone knife.

On the one hand, he believed Han Cheng's words very much, but on the other hand, he felt that the iron knife should not be that sharp.

The bone knives in the tribe would be fine if he held the blade with his hand. Although this iron knife looks sharper than the bone knife, it should be fine if he holds it with his hand.

And the Son of God had touched it just now, and his hand was not cut...

Seeing Wu's expression, Han Cheng could basically understand what he was thinking.

He stood up holding the iron knife which weighed less than half a pound, and took the leather placed beside him, ready to use it to test the knife, so that Wu and others could see how sharp the iron knife was, and at the same time test the results of his labor over the past few days.

Just as he was about to do it, he suddenly remembered the legendary swords and other things that had come into the world, and his heart was moved.

When swords like Gan Jiang and Mo Ye were forged, human sacrifices were required, and some swords could not be returned until blood was shed.

Now the first iron knife in the tribe appears in my hands. This is my first time trying out the knife, so I can’t do it so easily. I should see some blood.

Although this iron knife looks really ugly.

Under the gaze of everyone, Han Cheng put down the leather in his hand, holding the iron knife in one hand, and slowly looked at everyone.

The confused crowd was also looking at their Son of God and the knife in his hand.

Han Cheng looked around for a while and his eyes fell on a stone not far away that was slightly taller than him.

Then mentioned walking towards the stone.

Stone didn't know what was going on, but when he saw the Son of God walking towards him with a newly made thing called an iron knife, he looked excited and took a step forward.

Han Cheng pulled up a weird smile, raised the iron knife in his hand, and walked to the stone.

Then……

Then he walked past him and went straight to the chicken coop behind the stone.

The others followed him.

The unusually arrogant old rooster in the chicken coop, seeing so many people coming to see him, not only was he not afraid at all, but he climbed onto the back of a hen like a stagehand and put on an X-rated blockbuster show in public.

After finishing, it flapped its wings and looked at Han Cheng provocatively with its head tilted.

Then the guy was caught.

Grab the base of the wing with one hand and bend its neck over, then step on the chicken's two claws with one foot to prevent it from moving.

Reaching out to pull out the hair on its neck, the knife that could be used to kill cattle was placed on the neck of this old rooster that loved to show off its affection.

Han Cheng pulled the knife with a little force, and the iron knife cut the skin on the old rooster's neck. Dark red blood flowed out and fell into the pottery bowl below.

Sprinkle a little salt on the blood, let it coagulate, and then stew it with chicken. It tastes delicious.

The old rooster, who had been tested with a knife and bled because of his arrogant display of affection, was thrown out. He flapped his legs twice on the ground, stretched out his legs, and died.

“Nice knife!”

Han Cheng praised himself secretly.

Although no one would want this knife for cutting vegetables in the future...

The adults were amazed that the iron knife could kill the chicken in one stroke, and the children became extremely excited.

But most of their excitement came from the completely dead chicken on the ground.

Han Cheng did not wipe the blood off the knife and used it directly to cut the skin.

The strong leather was spread on the wood. Han Cheng held the leather with one hand and held the knife with the other hand, cutting from top to bottom.

After one cut, the leather was slightly broken, and Han Cheng continued to repeat along the previous cut mark.

After the ninth cut, the leather was completely cut in half.

Han Cheng frowned as he looked at the knife in his hand. The knife was not sharp enough without steel blade. He had to use so many knives to cut the skin. He would have to throw it away in the future...

He took his eyes off the knife and looked up to find that the people around him were looking at him with stunned expressions.

Han Cheng couldn't help but sniff.

I had too high expectations for the sharpness of the iron, and now the iron will be looked down upon by the people in the tribe.

"God...Son of God..."

The once very silent scene was finally broken, and the one who spoke was the most mature and steady witch.

But now he spoke with a stutter and his voice trembled a little.

Han Cheng's face turned red, and he couldn't help sniffing again, thinking that the people in the tribe were really shocked by the "sharpness" of the iron.

It turns out that you can't be too confident.

Wu was truly shocked. This iron knife could actually cut through the leather!

This is leather!

So far, the method used by the people of the Qingque tribe to open the leather is still the method originally used by Han Cheng - rubbing it back and forth on the stone edges.

It’s not that they don’t know how to innovate, but that the conditions don’t allow it.

They also tried other tools and other methods.

Stone knives and bone knives are of no use to the skin.

As a relatively idle person in the tribe, besides playing with rabbits, he often observed the women in the tribe making clothes, and even ground the leather himself, understanding the difficulty involved.

Now seeing that the knife made of iron by the Son of God could cut the leather so easily, many times faster than friction, how could he not be shocked?

Moreover, the Son of God has not grown up yet and does not have enough strength. If an adult holds the knife, wouldn’t it be faster to use it to cut leather?

This...what on earth is this iron? It's so magical?

No wonder the Son of God didn't let me touch it with my hands just now. According to my previous thoughts, my hands would definitely bleed!

If cutting the skin is so easy, then if it is used to kill prey or enemies, wouldn't it be...

Wu's old face turned a little red.

The eldest brother and others also looked eagerly at the knife in Han Cheng's hand, and their expressions changed from initial shock and dullness to excitement.

"God...Son of God..."

Wu didn't know what to say for a moment and could only repeat this sentence.

Han Cheng sniffed again. Damn, this was really embarrassing.

Even an ugly daughter-in-law has to meet her parents-in-law. What is going to happen is bound to happen.

He immediately made up his mind and handed the knife to the witch.

Unexpectedly, Wu took the knife with both hands and cut the skin with twelve strokes. Then he bowed to Han Cheng with both hands holding the knife and praised loudly: "Son of God!"

The others also shouted excitedly, "Son of God!"
