Song Xuan is not greedy, he only trains twenty people every day, so that he can understand the situation mastered by everyone more clearly, basically after half a day of training, he is almost able to go directly to plant rice, so after a few days, most of the captives have also learned how to plant rice.

Although it seems that it is not difficult to transplant rice, the depth interval is very knowledgeable, and these things have a great impact on the future growth and yield of rice, which can be seen even by a group of rough men like Teng Snake.

At the beginning, the seedlings in charge of the women looked much neater than them, and the depth of the seedlings was relatively consistent, unlike the seedlings they inserted, some were deep, some were shallow, and the height was different, and the gap was even very large.

This is also reflected in the yields, which are significantly higher than the final yields of the rice grown by the women. Shi Meng and they are more, although one or two acres of land are not obvious, but if they are added up, each piece of land can have a difference of twenty or thirty catties, and some good and bad can even be more.

Counting a few hundred acres of land, it is a thousand catties, which is still very scary, which is why Song Xuan attaches so much importance to the distance, after all, Teng Snake is going to gradually transform into an agricultural tribe, and it is natural to slowly increase the requirements for this, only when the yield of rice is raised, can the tribe free up more manpower to carry out other activities, instead of wasting most of the time looking for food.

Just when Song Xuan cultivated everyone to learn how to plant, the refining of bronze had already begun, but the amount of ore was too much, and the stone alone must be worth it, and he couldn't be busy, so he added another person to the original foundation, Teng Snake is now just firing pottery, and there are four people in this aspect of bronze.

Of course, these four people are Teng Snake's own people, there is no need to worry about the safety at all, the pottery is okay, it is easy to figure it out, although the surrounding tribes have not yet figured it out, it is only because the time has not come, but the bronze does not allow Teng Snake to be negligent, which is a very important thing for the entire tribe, so the selection is naturally very strict, Song Xuan asked the two tribes of Kite and Xiong to elect people to come out, whether it was Kite Rain or Xiong Er, they directly refused to say that they would not participate, Although Song Xuan trusted them very much, the two of them also knew that they had just joined Teng Snake and it was such an important thing, so it was naturally best to hand it over to the people who originally belonged to Teng Snake.

Although the number of people has increased, several of them are mainly responsible for firing pottery, and the bronze work is still mainly controlled by the stone, although they will also be involved, but when it comes to the critical time, several people will take the initiative to avoid it, because the divine envoy has already said that only two people in the tribe are allowed to know the specific proportion of refining bronze, one is a stone, and the other is Song Xuan.

Of course, in order to avoid accidents after the successful refining, Song Xuan will also let the stone fire a pottery plate with detailed records and store it in the tribe, if the two of them really have an accident, they will not lose the inheritance in the future.

Of course, the premise of all this has to be successfully refined, after a few days of exploration, for how to refine the copper in the copper ore, the stone is already handy, in order to ensure the quality, the first is to screen the ore, and then it is crushed, the purpose is to remove the obvious impurities, these impurities are naturally soil and gravel.

The second is also for better refining later, although it is very laborious to smash the stone, but it can reduce a lot of charcoal, although the tribe is not short of wood, but after all, it is to be collected manually, and it has to be fired, and the requirements of the stone are relatively high, and a large amount of charcoal will be consumed every time it is fired, and the pressure in this regard is not small.

In addition to mastering the refining of copper, tin ore has basically been determined, among the ores collected by the tribe this time, at least four of them can be successfully refined from metals, of course, the proportion of copper and tin is a little more, and the other two ores Song Xuan did not distinguish, but vaguely felt that one of the red colors may be iron ore, but because the content is too low, it has no substantive effect, so after determining the tin ore, I don't want to think about other metals for the time being.

For the current Teng snake, bronze is the most suitable metal, and iron ore or something, although the quality is definitely better, but the requirements for flame will be higher, and the current knowledge of this mine has not found high-quality iron ore, in this case, it is better to focus on the present, with the most suitable for yourself, and this is basically in line with the historical law in Song Xuan's memory, after all, the world he is in is also such a step, and bronze has lasted for thousands of years, It shows that it is still very difficult to smoothly transition to the Iron Age, and it also shows that bronze can fully meet the needs of the current Teng Snake, but there is no need to be too entangled.

What the stone is doing now is to refine as much copper and tin as possible, copper ore is relatively difficult to refine, and the requirements for temperature are very high, but fortunately, charcoal can still be reached at this temperature, although Song Xuan also knows that there is such a thing as coke, but there is indeed no exposed coal around the tribe, so it can only be used improvised.

Tin refining is much easier, it is basically melted as soon as it is burned, and it does not take too much effort.

Song Xuan also asked the stone not to be in a hurry to try, first refine both metals, and at the same time reduce the impurities in them as much as possible, and then slowly experiment with the specific proportions, since it has been determined that there is copper and tin, and even make a small batch of it, there is no need to rush to make bronze tools.

On the contrary, it is easier to find the specific ratio, of course, it is not difficult, it is nothing more than trial and error.

Song Xuan still has some experience in this, he plans to arrange the ratio of copper and tin in half to half at the beginning, and then gradually increase the proportion of copper, after all, it is called bronze, and it can be seen from the name alone, the proportion of copper in it must be higher.

At that time, you can arrange several more groups at the same time, and make different proportions, and I believe that you will soon be able to find the most suitable ratio.

If it goes well, it is estimated that it will be able to figure it out in a day or two, and Song Xuan also did not expect that the quality of the ore mined this time is so high, the top two ore types are copper and tin, and the other stones account for a very small amount, and even the latter ones add up to the number of tin ore.

In order to make the experiment more rigorous, Song Xuan even figured out the scales, which was almost not needed in the previous tribe.

Said to be a weigh, in fact, it is just a small balance made of wood, but it is still relatively sensitive, and the small hook scale is also being made, since there is a need in the tribe, Song Xuan simply unified all the weights and measures, whether it is weight, volume and length, there is finally the most detailed version in the Teng snake.

Of course, this is basically according to Song Xuan's memory, although there will definitely be errors, but it will not affect it.

"Oracle, it's almost!!"

"Let's go!"

Since the stone has been almost prepared, Song Xuan has not delayed, he has been waiting for this day for a long time, and the tribe has finally stepped into the Bronze Age with half a foot.

Each crucible has a yellow copper ingot and an off-white tin ingot, because the density of tin is smaller, so it seems that the volume is much larger, but both have been weighed before, basically there is no error.

Then the two put the crucibles into the brick kiln, now there are a total of six crucibles, the small blast furnace is naturally a little insufficient, in terms of firepower and size or the previous brick kiln is the most practical, and the blower has been improved many times, it can also fully exert the temperature of the charcoal, and it is very handy.

At this time, there were only two people in the brick kiln, Shi and Song Xuan, and the other three were all arranged to guard nearby, and no one else was allowed to come over in this area.

Looking at the three people guarding outside the brick kiln, Teng Snake and the others were also a little nervous, they also knew that the Divine Envoy had begun to make bronze, and after waiting for so many days, there was finally a result, but Song Xuan also took a preventive shot with them, that is, the process may not be so smooth, but as always, the trust of the Teng Snake people in the Divine Envoy is unconditionally amplified.

Although the brick kiln is larger, the firepower is still a little weaker than that of the blast furnace, although it can barely reach the temperature of melting copper, but it is more time-consuming, and the two of them pulled the bellows for nearly three hours before the copper in the crucible was completely melted.

After all the copper had melted, it burned for another half an hour, then the fire was extinguished, and the crucible was made of wood, and then the pouring began, and the molds were made in advance.

In order not to delay the experiment, the stone asked others to make hundreds of molds in advance, and there were different kinds of tools, axes, hammers, knives and even arrows.

This is because different tools have different properties for bronze, some need to be sharper and more wear-resistant, and some need to be harder.

Only by comparing with each other can we understand the most suitable amount required for each tool.

Six crucibles, the proportion of copper and tin in each is not the same, because it is not yet accurate to a finer degree, so the proportions are rounded, but even so, the things made are absolutely enough, as for the finer proportions, you can only wait for the future to continue to ponder, on this road, Teng Snake must be pondered for a long time.

In a blink of an eye, it was already lunchtime, but the cooling of the bronze also took a long time, and the two of them did not dare to use water or something like that to accelerate the cooling, for fear of affecting the quality of the finished product.

But this matter is too important after all, so Song Xuan also asked the three people outside to bring over the food, and the two of them did not leave here for a moment.

Fortunately, the result was still very satisfying, and by the time it was almost dark, the bronze had finally cooled down completely, and the two men had taken apart the molds and compared them one by one, while the stone had carefully polished everything like knives and arrows.

After everything was ready, the real experiment began, first of all, the cutting ability of the knife, the two took the tree that they had cut back this morning, and then they picked up the knife in their hands and cut it down, one after another, and after a dozen strokes, they compared each other to see the situation of the blade.

Then they slashed each other, and Song Xuan also knew that if the knife was too brittle, it would not be conducive to fighting against people, after all, the knife that was too brittle would be too easy to break.

Then there were axes, hammers, arrows and the like, and the two of them made a very detailed comparison, although the moon had jumped on the branches, but the two of them were very excited, and when the two experimented, the snake and everyone did not urge.

Although most people were worried that Song Xuan would be hungry, the divine envoy had already said in the morning that the rest of the tribe was absolutely not allowed to approach before they came out, and the three people who were patrolling outside asked once, but they were also rejected by Song Xuan who was excited, and what they were doing now was obviously more meaningful than eating.

"Yay~"

This is also a rare stay up late after Song Xuan came to the Teng Snake Tribe, and the two of them tried until midnight, which made the proportion of bronze tools used in the tribe now determined, although it is certainly not the most perfect state, but at present, it can far exceed the tools used.

Now that it has been determined, it will be able to gradually carry out refining in the future, and let the Teng Snake people use the bronze as soon as possible.

The two people who watched the tinkling in the middle of the night finally walked out, and the Teng Snake who was looking at the door all breathed a sigh of relief, they had already seen the smiles on their faces from a long distance, obviously the experiment was very successful.

"How's it going?"

Although Song Xuan didn't speak, the expression on his face really said everything, and then he also shared today's experience with Teng Snake everyone, of course, the specific proportion will definitely not say much, at the same time, Song Xuan and Shi also handed over several tools of the best proportion to Teng Snake everyone, although it was the middle of the night, but the person who got the weapon couldn't help but test it himself, and even Shi Meng compared it with his own weapon, obviously the quality of the new one made today is better.

"Bring the food !!"

Song Xuan, who had been busy all day, finally felt the attack of hunger at this time.

But all this has already been prepared, Xue'er has already delivered the food to Song Xuan, and he has not eaten until now, Song Xuan is also hungry enough, and devoured two large bowls of broth, and then patted his stomach with satisfaction.

And after the stone was made of pottery, it was once again supported by everyone, although the leg was not good, but Shi Meng still led someone to throw him into the air, mainly because they definitely didn't dare to do this kind of thing on Song Xuan, only the stone came, fortunately, other people also deliberately paid attention to this aspect, and would not let him get hurt, Teng Snake Everyone has been fascinated by it for a long time since they knew that there was a bronze thing, especially last year, the bronze was finally made.

Everyone finally really experienced the power of the bronze in the mouth of the divine sense, but due to the scale limitations, only a few leaders can use it, and most people still don't have the opportunity to use it, and now, it can finally be popularized on a large scale, Song Xuan also told the Teng Snake people about the general plan, according to these stones dug from the Wuyu tribe, the bronze refined in the end must be able to meet everyone's needs, but it should only be one person, and if you want more, you can only go again, But even if it's just a handful, it's already very enough for the Teng Snake people.

Teng Snake and the gods, who had used bronze weapons, naturally knew that even just one weapon could make a drastic difference in an individual's strength.

Especially knives and bows and arrows, knives are very popular among the tribes because they are very easy to use, and the previous stone knives are completely opposite to the two states, and the people of Teng Snake basically do not take the stone knife out to hunt or use it when fighting with people, mainly used to cut meat and cut and hide.

The same is true for bows and arrows, the Teng snake bow and arrow is not lacking in range, the most important thing is the power, once it exceeds forty or fifty meters, the penetration is quite limited, if the clothes worn in winter are thicker, this power will be attenuated by a few points, but the bronze arrow is different, even if it is at a longer distance, it can ensure sufficient penetration.
