This mold is placed next to the flame technique. The moisture inside has been dried and solidified, so there is no need to worry about the mold cracking after the high-temperature copper liquid is poured into it.
After waiting for the copper juice in the mold to cool and form, there is a "ding-dong-dang" beating.
These processes did not take long, because there were totem warriors such as Yan Hu and Cang Shi. They were very powerful and controlled their strength very carefully.
Therefore, a tool model was quickly formed. After it was formed, it was the same old process. The flame continued to burn, and river water was taken to cool it before being hammered.
Generally speaking, although copper weapons do not require as much refinement as iron weapons, this step cannot be omitted because this step is related to the hardness of the weapon.
Otherwise, if a weapon is made to be sharp but not hard enough, it still won't work.
Soon, with the joint efforts of everyone, a copper knife model about half a meter long was successfully made.
But this alone is not enough, because this long knife does not have a sharp edge, it is just a blunt instrument.
The final opening work was even simpler. Yang Cheng found a stone with a frosted texture and asked Yan Hu to take the knife and start sharpening it. With the strength of Yan Hu's fifth-grade totem warrior, he cut a half-knife. It is not difficult to sharpen a meter-long knife.
Yan Hu quickly completed the task assigned to him by Yang Cheng.
"Witch, it's finished."
Yan Hu handed Kai Feng's copper knife to Yang Cheng.
To be honest, this copper knife doesn't look very good. Although its shape is somewhat curved, both sides are not very smooth. This is because the mud mold was not made well.
After all, Yan Lin and Xing were not the clever Lulu, and they still had some shortcomings in pinching mud, so both sides of the knife had some bumps and the shape was a bit awkward.
This can be easily solved. After returning to the Qingque tribe, Lulu can make the next batch of molds for making weapons and farm tools.
In addition, the biggest problem with this bronze sword is that Yang Cheng forgot to design a handle for it.
Now it is not so much a bronze sword as it is a curved blade. It is extremely ugly and far unlike the bronze swords Yang Cheng remembers seeing in movies and TV series.
But apart from these two aspects, Yang Cheng is still very satisfied with the rest.
First of all, it is relatively sharp. If you wave it in the air a few times, you can hear the sound of the blade piercing the air. Under the sunlight, its blade can also reflect dazzling light.
This is all due to Yanhu's carefulness when attacking, and because he is very strong and does not need to rub back and forth.
The second is that this copper knife is relatively large, half a meter long, much larger than the "little dagger" Yang Cheng made from copper ore before.
Yang Cheng's small dagger is less than fifteen centimeters long. It can only be used to peel wild fruits or vegetables. It can be used as a kitchen knife. As for cutting people, the totem warrior's defense can only be broken. , unable to cause fatal damage.
"Try it."
Yang Cheng turned over the bronze knife in his hand and looked at it for a while, then handed it to Yan Hu and asked him to try it.
"Try it?" Yan Hu asked doubtfully, "Wu Wu, how do you want me to try it?"
"Well... it's very simple. Just cut down a tree or some branches or something." Yang Cheng said.
"good."
Yan Hu nodded, then carefully took the bronze knife from Yang Cheng's hand, holding the back of the knife with his hand. The blade was sharper. Even Yan Hu, who was a fifth-grade totem warrior, did not dare to use force to completely cut the knife. Hold it on the edge of the knife.
When Yang Cheng saw this, he frowned slightly.
If you cannot fully grasp the blade, you cannot use the power of this bronze sword.
"Yanhu, wait."
Yang Cheng called Yanhu to stop, and then asked someone to find a thin vine and tie it to the tail of the bronze sword. This way, there was a handle that Yanhu could completely put his hand on.
After doing all this, Yang Chengcai said: "Okay, you can try it now."
Yan Hu nodded and tried to put all his hands on the blade to make sure it would not hurt himself, and then shook it hard.
After doing this, his confidence greatly increased, and then he went to a big tree by the river that was hugged by one person.
"Hey."
Yanhu took a bronze knife and chopped off the thumb branch on the big tree.
"呲——"
"Wow!"
The branch was cut directly to the ground by the bronze knife, and even the knots connected to the big tree were cut off directly——
On weekdays, the tree knot is the most troublesome place for everyone in the Qingque tribe, because the sharpness of the stone ax alone can cut off the branches, but after each cut, the place where the branches and the big tree are connected is The most difficult thing to remove is that a pimple will be left every time.
You still need to use a bone knife to dig out the lumps, so that you can get a complete trunk.
The bronze knife in front of me can actually cut off the tree knots completely without the unnecessary step of using a bone knife.
Seeing this in the eyes of everyone in the Qingque tribe, everyone's eyes showed excitement.
The Stone Tribe and others were completely stunned on the spot. They did not expect that Yang Cheng would actually make something that looked like a stone knife after tinkering with the copper ore.
This stone knife seems to be very sharp and can actually cut off branches in one go.
You must know that when the people of the Stone Tribe collect branches, they never consider taking branches from the trees. Instead, they directly pick up the branches that have become dry and fallen on the ground, because getting branches from the trees is very troublesome and requires a lot of effort. !
But before Shi Liang and Shi Chang could react, at Yang Cheng's signal, Yan Hu took a copper knife and struck at the trunk of the big tree in front of him.
"bump!"
"bump!"
Under Yanhu's strong force, the copper knife in his hand came into close contact with the big tree. The big tree was immediately cut open by the copper knife, and then the wound became bigger and bigger. Deeper and deeper.
However, under the shocked eyes of the Stone Tribe and others, this big tree as thick as a person collapsed!
"bump!"
The big tree collided with the ground, stirring up a lot of dust.
"Is this...is this a miracle?"
Shi Liang murmured to himself, unable to believe what was happening in front of him.
This big tree, which is about the thickness of a human being, is not considered a big tree in the primitive forest. There are many trees that are even bigger than it. Instead, it is just a big tree about the thickness of a human being, and it can be regarded as the smallest tree in the primitive forest.
However, for such a thick tree, it would usually take a lot of effort for the Stone Tribe to cut it down. Not only would it take an hour or two to cut it off, but they would not even know that they would lose anything in the process. How many stone axes!
