The sky was overcast and the wind was cold.
Ji Lin's wooden wall was more than half completed, and a man with a rattan hat rode on a nailed stake, holding a stone and smashing down a stake.
Under the wooden wall, men and women used various tools to cut and burn wood more than three meters long, and after cutting it, they helped it up and erected it next to the wall, allowing the men to continue smashing.
Another woman and child drove away the ghost eagle on the wooden wall and hung thorns on the wooden wall, and the ghost eagle fell on the wooden room quite dissatisfied.
In the open space in front of the wooden house, the eagle and the red monkey and others were rubbing the mud hard.
I don't have time to pay attention to the ghost eagle.
Da Ji and a few women gathered around the small blast furnace to keep burning the fire, and some people muttered that the time was up, there was not even the sun today, and I really don't know how long it had been.
Some people also looked into the upper hole to see if the fire inside was red.
The temperature on the small blast furnace was so high that the ghost eagle hardly dared to approach it, and it didn't know what was burning inside.
The ghost eagle turned his head to look through the window of the wooden room next to him, and saw that the terrible boy was turning over a strange object, which seemed to be made up of many leaves, but each leaf was white and dazzling, and there were many strange patterns on it.
The eagle had amazing eyesight and could see the patterns, and although it didn't know what they meant, it thought the patterns were interesting one by one.
Suddenly, there were several shouts from outside the wooden wall, and the ghost eagle was surprised to see that the terrible young man's hand flashed, and immediately turned into a black short stick.
The terrible boy turned his head and aimed his short stick at the ghost eagle, and his mouth snapped.
The eagle screamed in fright and almost fell off the roof.
Lin Ji turned his head and listened to the movement outside, put away his pistol and walked out of the wooden room, and beckoned to the ghost eagle: "Come down." ” Where there is a door left on the west side, Hair Arc is running back with a few men covered in dust: "Where is the pottery made?"
These men were the first to be sent out to build beacons and outposts.
After the new pottery was burned today, Daiki asked them to replace them so that they could also feel the taste of an ample broth from the revelation of the god of chestnut.
Looking at this, they are afraid that they will run all the way back.
Sure enough, they came back and said hello to Da Ji briefly, and then went straight to the place where the pottery was kept.
Their way of worship is to eat all the broth left over from the morning The ghost eagle reluctantly came down from the roof under the beckoning of Lin Ji, and was soon pinched by Lin Ji and was taught a lesson: "Peek at me, let's say, what have you seen, don't say that the cat will bite you."
If you don't say it, it's just right.
Don't tell anyone you know."
The ghost eagle was pinched in the mouth, and it was simply loveless.
It didn't dare to resist at all, and the slightest resistance would be the end of starvation with its feet tied and rocking.
The most terrifying thing is that the wild cat is circling around every day, and as soon as the forest trail opens its mouth, it really appears not far away.
This wild cat may not be short of food recently, and its size is constantly getting bigger, although the ghost eagle has also begun to regain its size and strength, but it has not fully recovered, and it is very difficult to deal with this wild cat.
If you are pinched like this, you will only be scratched.
The eagle stopped to make a mold, and also looked at the forest traces with some resentment.
This guy is always nervous sometimes, and he is very good to people, and he is always so inexplicable to these cats and dogs.
He himself clearly said that animals can't speak, and now what are you doing with the ghost eagle, it's really not that his own child doesn't feel distressed Maybe it was the eagle's glare that upset Lin Ji.
After Lin Ji let go of the ghost eagle, he came to find fault.
He scratched his head and said, "I thought about it for a while, the one-foot-long spearhead is too long, and the thickness we thought of seems to be a little thinner, the bronze is more brittle, so it's better to use a short and thick shape."
The machete is too long at two feet, and it is almost the same if it is one foot long, but the back should be thicker.
Don't want the arrow cluster, it's too wasteful at the moment, because it's too fine, and it's not as good as the bones.
The axe is still the same, let's see how it works, and then adjust it."
After all, there is no Internet access in the small town, so the information found is very limited.
In Lin Ji's vision, even if he can't get Qin Shihuang's seven-foot long sword, it should be no problem to make a little iron-level thing in later generations.
As a result, after looking for a round of information, I found that it was also difficult.
He searched around and found a bit of proportions in a bronze catalogue.
Bronze weapons have a copper-tin ratio of five to one.
He found the chemical formula of malachite in a physics textbook.
It was determined that carbon could be smelted from malachite for copper, and the other products were carbon dioxide and water.
As for how to remove impurities in the copper smelting process and what is the optimal ratio of bronze, no information was found.
Poor proportions can't remove impurities, don't think about what kind of exquisite and sturdy bronze you want to make.
It's better to give up those unrealistic fantasies and get something stupid and coarse, but more practical.

Anyway, I'll start by myself, and let the eagle slowly grope for the back.
The eagle looked down at the circle of clay molds under his feet, eighty percent of which were going to be redone, and he couldn't help but feel even more resentful.
It's all about whether you think about it or not, there is no "we".
After another day, there was still no news from the gray wolf, but the tribe's wooden village had basically closed.
With the constant stimulation of broth and pottery, everyone's motivation has increased more than a little.
This is the result of many people staying up late.
The good news for this day is that Daiki and several women also burned pottery.
Although the result is more pitiful burn six out of two.
Lin Ji led people to open the charcoal pond and took out the basket of charcoal.
After turning around, he cleaned and repaired the inside of the small blast furnace, connected it to a simple blower made of animal skin and mud pipes, and began to smelt copper.
Lin Ji took out a scale composed of wooden poles and stones, weighed the relatively small malachite, and spread it with charcoal into the blast furnace layer by layer, and then ignited the fire.
Smoke and flames erupted from the top of the blast furnace.
This time, Da Ji brought a few women around, except for a few people who did the work in the forest tracks, no one else could look this way.
Lin Ji commanded the vermilion monkey to blow the wind, and he and the eagle explained the wooden scale.
It was made in imitation of the wood found in the town.
The stone used to make the weighing stone weighs the same weight as the original weighing stone.
It's not going to be too precise, but it's better than nothing.
After speaking, Lin Ji talked about the copper ratio of malachite.
The basic properties of copper and the difference between copper and bronze.
When Da Ji heard this, he almost wanted to blast Zhu Monkey and the others away, and practice these by himself.
Lin Ji said: "In the future, the children of our tribe will learn these things, so there is no need to hide anything from them."
Everyone knows what's going on, so these things won't be broken because something happens. ” Da Ji only gave up when he heard Lin Ji say this, but strictly ordered them not to tell these things to others.
With these things, Da Ji will not exchange Zhu Monkey and the others.
The eagle listened to the bronze recipe and asked, "Where did we get this tin?"
Lin Ji said: "I'll get a little bit of this for the time being, just take it from me first."
Let's go back to the copper mine and look for it. ” The melting point of copper is a little more than 1,000 degrees, and after malachite and charcoal react, the remaining copper is melted at high temperature, and it becomes copper water that flows to the bottom of the furnace.
When Lin Ji saw that it was almost there, he threw the prepared tin into it.
The melting point of tin is only more than 200 degrees, and it melts almost immediately in the furnace.
After the two were mixed, Lin Ji opened the liquid outlet, and the eagle used a small clay pot with a wooden handle as a crucible to pour out the alloy liquid and pour it into the molds one by one.
After a while, when the temperature dropped slightly, Lin Ji picked up an axe pimple with a wooden clip.
The axe has a blunt edge, and there is a lump of excess copper on it, which looks extremely ugly.
Obviously, it needs to be polished before it can be used.
But when Daji and the others saw this object, they could hardly take their eyes off.
Where is this bronze This thing is golden and beautiful, how can there be a little cyan appearance Lin Ji patted his head, and then remembered that the bronze was called bronze when it was unearthed, and it was oxidized to cyan on it.
When it was first minted, it was this gold, called Jijin
