Thanks to the 100 starting coins rewarded by ~Cold Flame~ brothers.

Jin San has observed for a long time and has also done experiments, and with the genetic drugs used by Jin San, these golden carp have grown to this extent.

He caught a fish in three days, which made Li Lin hate it so much that he even sent someone to dive down to search for the golden carp, but he found it, but it was not so easy to catch it.

When the reservoir was built, it was simply dredged, and the waterways between the two mountains were blocked, so the situation in the reservoir was extremely complicated.

There are many places where even if you get out of the net, it will be blocked by rocks or gutters, and you can't completely catch the net, so many times, even if you find a golden carp and sprinkle the net over the golden carp, you won't be able to catch it.

Li Lin and the others have also netted the big fish several times, but the power of the big fish here is too huge, often at the first time, their fishing nets will be directly dragged away by the big fish with brute force, not to mention the net fish, which also makes them lose a lot of fishing nets.

Li Lin, who suffered heavy losses, finally had a harvest now, he immediately asked Chu Yunhe to dispose of the golden carp, and with the newly made golden pill, he left the Jin family, killed in the capital, and went to find backup.

If you want to do a good job, you must first sharpen your tools, and Li Lin can be regarded as understanding, not that he is incompetent, but that the enemy is too cunning.

His equipment is not good, but sharpening the knife is not a mistake for a woodcutter, first find some good equipment, and then gather some talents, he doesn't believe it, and he can't deal with some fish and shrimp without wisdom.

Li Lin left, but Chu Yunhe and some of the guards left by Qian Jun did not, and the guards wanted to help Jin San guard his family's reservoir, after all, this place is now considered an important place.

Chu Yunhe was left by Jin San, Qian Jun took away a lot of things from his Jin family, so he naturally wanted to give Jin San some benefits, and Chu Yunhe was one of the benefits.

Now there is Zuo Qinglong in Qidu City looking at Jin San's foundation, so Hou Zhong doesn't go to the city anymore, he sits at home, and now he is going to get more caviar, of course, now Hou Zhong is called Jindan, he wants to make this industry bigger.

And Jin San also wants to limit the reproduction of golden carp, and now he doesn't know how many golden carp there are underwater, he wants to hunt some and see how many there are underwater.

This thing can be killed, as long as a few are left, it only takes a year, and they will immediately reproduce in large numbers, and the evolution of animals is mutation and heredity.

Now that the mutation of the golden carp has been completed, the genetics are also very stable, and the golden carp specially bred by these golden three has inherited the fact that it grows rapidly.

Jin San deliberately tracked a few small golden carp, just a few days of hard work, those few little golden carp, grew to two or three catties in size, such a growth rate, although not as fast as Jin San with genetic medicine to spawn, but not slow.

At this rate, it doesn't take a year for these small golden carp to become adults, and adult golden carp, which are generally about two meters in size, grow to this extent, and then grow slowly.

Jin San observed for a few days, and the golden carp he first cultivated grew to three meters long.

Every time Jin San enters the reservoir, he will bring some watermelons or tomatoes or something to feed him.

It has really become the overlord of the reservoir now, and every time Jin San feeds it, it will attract a lot of big fish, but those big fish, after being attacked by the golden carp king a few times, have never dared to offend it.

Seeing Hou Zhong excitedly helping Chu Yunhe to deal with a golden carp, Jin San didn't know what to say.

Hou Zhong, this kid, as long as it is something that can make money, he will do it with a hundred times more energy, no matter how much he earns or how little.

Professor Yuan was also very busy, and heard that he had already produced some research results, but Jin San was not interested, and directly told him that all the results of research were his.

So the old man was more energetic, and I heard that now he had brought in a few students, and they had been in his humble laboratory for several days.

Jin San hasn't been to the laboratory for the past few days, and with Old Man Yuan there, it's inconvenient for him to do something.

Since he can't study plants, Jin San simply studies some metallurgy or something.

Since he saw the Republic Ding, Jin San wanted to study this thing, he had watched the manufacturing technology of the Republic Ding, and now the Republic Ding has fallen in the ancestral house.

Jin San used the camera to activate the time ability and recorded the entire firing process of the Republic Ding.

After a few days of research, he already has a clear understanding of the bronze manufacturing of the Western Zhou Dynasty, and he is just one more time away from him.

Jin San asked Hou Zhong to collect some malachite for him, he wanted to use this beautiful stone to smelt copper, and the bronze mining and smelting industry was gradually recognized from the production practice of stone tool processing and firing pottery.

In the process of searching for stone and processing, people gradually identified natural copper and copper ore.

For example, malachite, the color is turquoise, and the texture of its section is similar to the feathers of a peacock, which is very gorgeous, so people call it malachite.

It is very easy to be found in the rock pile, malachite has a high copper content, and its copper content can reach 10-20% or higher, so the ancient bronze is almost all smelted with malachite.

Malachite is a kind of oxide ore, as long as it is smelted in a furnace with charcoal, heated to a slightly higher temperature of 1000 °C, copper can be smelted.

It is often found with natural copper and has a similar color to patina, so malachite is probably the earliest copper ore used for smelting.

Jin San wants to restore the firing process of Western Zhou Dynasty bronzes and copy the Western Zhou Dynasty bronzes, so he naturally has to be infinitely close to the ancient smelting environment, whether it is the process or the material.

In the process of firing pottery, the rich experience accumulated by Kinzo has provided a lot of help for the smelting and casting of bronze.

The firing temperature of black pottery and white pottery in Longshan culture is close to the melting point of copper.

Techniques such as using pottery molds to make clay and printing patterns are similar to the mold functions of cast copper.

The furnaces, water colors, and shapes used for smelting and casting are all pottery utensils, and the charcoal used for copper smelting is also the same as the fuel used for firing pottery.

In ancient times, when people were making stone tools, when they were haunting the hills and jungles in search of raw materials, if they found natural copper and malachite and other copper ores, the first thing they mined was the natural ore on the surface.

Jin San wants to use the ancient method to smelt copper and reproduce the perfect ancient bronzes, so he naturally has to be infinitely close to the ancient craftsmanship, so that the bronze refined is the same as the one refined in ancient times.

However, the cost of using malachite to smelt copper is still a little high, so Hou Zhong has asked people to go to Hu, Bei, Jiang, West and other places to go to those ancient mine cave sites to collect some copper ore.

Hu, Beidaye Tonglu Mountain, Jiang, Xi, Rui, Changtongling and other places, there are Shang and Zhou mining sites, because most of them are distributed in the contact zone between igneous rock and marble, and the rocks in the contact zone are broken and relatively easy to mine.

Due to atmospheric precipitation and leaching, the copper elements on the surface of the ground are relatively concentrated in the contact zone, and the phenomenon of gradual enrichment of copper grade from top to bottom occurs, forming an oxide ore enrichment zone.

This condition makes it an ideal place for copper mining for ancient ancestors, and the ores here, mainly malachite, silicon malachite, cuprite, etc., are all oxide ores.

At that time, the method of smelting copper ore was to put the ore and charcoal in a smelting furnace.

Since these ores are oxide ores, this smelting is called oxide ore reduction smelting.

Although only the copper smelting shaft furnace in the Spring and Autumn Period has been found, and the smelting furnace in the Shang and Western Zhou dynasties has not yet been seen, Jin San found from the radio frequency photographed that the smelting furnace used in the Western Zhou Dynasty is very similar to the copper smelting shaft furnace in the Spring and Autumn Period.

The copper smelting shaft furnace in the Spring and Autumn Period must have inherited the shaft furnace of the Western Zhou Dynasty, so Jin San cultivated a small shaft furnace by himself.

In the Spring and Autumn Period, the smelting of copper shaft furnaces was very good, and it could continue to feed, continue to discharge slag, and intermittently release copper.

The copper smelting technology of the Spring and Autumn Period was developed on the basis of the copper smelting technology of the Shang Dynasty and the Western Zhou Dynasty, and the large amount of copper used from the unearthed Shang Dynasty and the Western Zhou Dynasty bronze ware may show that the copper smelting industry at that time was still relatively developed, and the smelting level of the Shang Dynasty and the Western Zhou Dynasty was not low.

To measure the level of smelting, it is very important to know the amount of copper in the slag.

Because the higher the silica content of the ore, the greater the viscosity of the slag, the poor flow of the slag, and the more copper it contains in the slag.

However, if the flux is added or the ore is blended, the viscosity of the slag can be reduced, and the flow of the slag can be good, and it will be flake when condensing.

Because the ore body of these sites is a copper and iron metal associated ore, the iron ore in the furnace, the ferrous oxide generated at high temperature is combined with silica, which reduces the content and viscosity of silica in the slag, and the flow of the slag is good, and after condensation, it becomes a thin sheet, and the copper contained in the slag is reduced.

During the Western Zhou Dynasty, the ore blending technology had been mastered in the smelting process, which reduced the copper content in the slag to 0.7%, which was a manifestation of the high level of smelting.

This kind of ore blending technology has appeared in the Western Zhou Dynasty.

After thoroughly studying the ancient smelting technology, Jin San worked hard for three days, and only made a few hundred catties of bronze, which was not enough to refine the Republic Ding, no way, Jin San refined two bronze forbidden.

Forbidden, is the ancient Chinese nobles in the sacrifice, feast when placed wine vessels several cases, mostly copper, the current surviving copper ban is very rare.

The bronze forbidden four sides of the golden three fired are decorated with a pattern, well-made, the ornamentation is vivid, it is a flat three-dimensional rectangle, hollow and bottomless, this bronze looks like a table from the modeling, so people called it a copper table at that time.

This thing is called the copper ban, the ban is the ancient Chinese aristocracy placed several cases of wine containers, three protruding oval sub-mouths on the forbidden surface, respectively, placed wine containers.

The bronze ban imitated by Jin San was completely cast in accordance with the copper ban of the Western Zhou Dynasty.
