Today is expected to be 6 more, this is the 3rd watch, and the last two watches may be a little later.

………

For the bronze proportion of the weapon, it is naturally required to have good toughness, and can take into account the hardness, so as to ensure the resistance to the blow at the same time, but also to improve the sharpness of the weapon, you must know that the weapon cast by the mold is impossible to open the edge, and the knife edge can only be polished later.

Compared with farm tools, toughness is secondary, only need to ensure hardness and sharpness, after all, such as the ploughshare, which is already cooked on the land of ploughing, and the possibility of breaking is very small.

Therefore, this problem has been recognized very early in ancient China, and there are strict requirements for the proportion of different bronzes.

At this stage, the Tianlong tribe has only summarized a rough data from the experiment, and the relevant improvement can only be improved through continuous accumulation.

After the two standards are formulated, it is necessary to start making molds for various corresponding objects, which involves a question of product type.

Now the most urgent thing in the tribe should be the lack of all kinds of agricultural tools, followed by weapons and equipment, copper hoes, copper shovels, copper ploughs and copper sickles for mowing grass are the most urgent, these must be obtained first.

Then there are all kinds of copper hammers, axes, carpentry tools chisels, saws, planing blades for planks, with these tools, wooden tables, doors and windows can be made horizontally and vertically.

Instead of the potholes that were cut directly with an axe, as is the case now, there is no beauty at all, and it is completely unacceptable for a designer to make such a product.

Previously, because of the tools, Wang Tian could only solve some problems first, but now with the materials, what Wang Tian wants to do most is actually replace all the dining tables and chairs in the canteen, and all kinds of shelves.

With these tools, the mortise and tenon structure can already be tightly fitted, but about the development of various mortise and tenon structures, Wang Tian also knows very little, he plans to wait for the tools to be manufactured, to make a childhood toy Luban lock out, with this to inspire the wisdom of everyone in the tribe, and constantly improve the structure of various mortise and tenon joints.

In this way, relative to the tribe, whether it is the production of tools or the construction of furniture houses in the future, it will have a significant impact.

This truth is like a cow clan after seeing the tribe's bow and arrow, immediately imitate a truth, primitive people are only because of their personal opinions, are limited to a range that they cannot break through for the time being, as long as this restriction is broken, all kinds of new ideas and new ideas will naturally follow.

Although Wang Tian is a traverser, he doesn't have a library golden finger like some great gods, he can find everything, and he doesn't bring his own warehouse, and all kinds of things can be used.

It has become an urgent matter to develop the abilities of the existing tribesmen, he only needs to guide one direction and make a little adjustment, and the rest of the things still need to be continuously improved.

Otherwise, all aspects of clothing, food, housing and transportation are put on

He was exhausted, and it was impossible for him to think it through, just like the reason why he knew the manufacturing principle of atomic weapons, but at the current stage of the Celestial Dragon Tribe, he couldn't even make a simple black gunpowder.

Things in the world are gradual, one era ahead is called an advantage, a few times ahead, then it is called a demon, even if he can maintain development when he is there, but what if he is not there?

His sons and grandchildren may be able to inherit his knowledge, but they must not completely inherit his vision, because this thing is not learned, and the ancient Chinese said that it is better to travel thousands of miles than to read thousands of books, which is what it means.

Now he tells his children and grandchildren that human beings can fly out of the earth, and airplanes and ships made of iron sheets can sail in the sky and water, it is estimated that his children and grandchildren will not believe it, this has nothing to do with the trust in Wang Tian, but their vision is not to that extent, how can something that they do not believe in become a reality?

The accumulation of civilization is like wealth, there is a process of accumulation, so that sustainable development can be achieved, and there will be no fault line in civilization.

Of course, the casting of weapons must also be completed, and the grassland trip after the snow is just in the face of the possible retaliation of the Niu clan, Wang Tian must be 100% prepared.

Similar to the Tang knives of later generations, halberds that combine the advantages of guns and ge, and metal arrows all need to be cast, and in the future, defensive armor like the Ming Guang armor of the Tang Dynasty will also need to be made.

In this way, even if it is two or three times the enemy of their own tribe, the Tianlong tribe does not need to worry too much when it encounters it, even if it can't win a battle, it can have enough strength to protect itself, plus the war horse, in this era, the world can go anywhere.

"Let's go, eat first, and then do it again in the afternoon!" The time has come to noon, and I plan to take out the drawings that have already been drawn after eating, or according to the old method of casting metal axes, first use weathered stone to make the outlines of various weapons, make models, and finally cast various tools and weapons.

At this time, Zhou was already waiting to measure the change of the shadow of the Gui table, Wang Tian estimated that the current time should have begun to enter November, and the daytime time was getting shorter and shorter, and before 5:30 in the afternoon, the sky had already darkened.

It should soon enter the beginning of the winter solar term, and it may even have passed, and the winter solstice should be only a month away, so in the past two days, he has instructed the heavens to find out the day when the daylight hours begin to get longer, that is, the winter solstice.

This is of great significance to guide the tribe's agricultural production in the coming year, after all, the number of seeds in the tribe is not very large, and these are very precious.

Sowing too early can cause the loss of seeds, planting too late to keep up with the needs of the season, it doesn't matter if the seeds are planted late, and the most important thing is that if you miss this year, you can only wait until the summer solstice half a year later, no matter in any era, time is precious.

During the meal, he was instigated by the second brother and the madman, the two weapon lovers, Wang Tianna

Having previously designed a manuscript, these two war fanatics have a natural love for all kinds of weapons.

The perfect weapons were vividly painted by Wang Tian with the technique of sketching, and their power could be felt through the paper.

The madman now holds a design drawing of a triangular arrow in his hand, and he is fascinated by it, the deeply sunken inverted blood groove, the barb like a fish bone, and the sharp arrow that is so cold that it seems to glow with cold light, makes the madman look yearning.

"Crazy, this kind of arrow is not trivial, once it is shot, the arrow is not in the flesh, there is no way to take it out without cutting the flesh and skin, you see that the mountain surface is not poured into the blood groove, if you don't pull out the arrow for stitching, the enemy or animal shot by this arrow will die quickly because of the bleeding, after this kind of arrow is made in the future, it is easy not to use, even in the face of the enemy, it is the same!"

After all, for war, Wang Tian just wants to capture prisoners, as long as the weapon can make the enemy lose the ability to resist, it is fine, and it does not depend on the number of people killed.

And the madman was eager to build it at the moment, and then install it on the bamboo pole for test launch, for Wang Tian's warning, this guy showed a look of excitement.

Isn't it to kill an enemy to kill him? He still can't accept and understand the statement of the Son of Heaven, but the Son of Heaven has been so cautious in admonishing him, so the power of this arrow is self-evident.

Wang Tian looked at this guy with a crazy expression, and he didn't need to turn on the stream of consciousness to know that what he had just said was in vain.

At this time, the second brother of King Kong could see a drawing with a Tang knife, and when Wang Tian was designing, even the unique lines of the Tang knife's blade were depicted in detail, and the fierce aura after the unsheath was undoubtedly expressed.

For a fierce man like the second brother, he felt that this kind of knife was good, but it seemed to be too light, and it didn't have much weight in his hand, so he didn't feel so comfortable to use, so he raised his worries to the Son of Heaven.

Wang Tian could only smile, found copper ore and tin ore, will weight still be a problem! You just want a watermelon knife weighing dozens of pounds, and I can make it for you.

As a carpenter, Liu Bei has a strong interest in all kinds of tools, he knows the power of metal axes, thinking that so many metal tools, if the manufacturing is successful, then his work will not be too easy in the future.

In short, in the face of various drawings, everyone in the tribe can find their own interests, as the so-called radish greens have their own love, even a group of women in the beast clothing cutting production team also looked at the scissors drawn by Wang Tian, secretly happy.

Although the small scissors on the Sky Saber are also very useful, after all, the size is too small, and long-term use will make the handshake painful, especially in the face of this thick fur, even if the small scissors are sharp, they seem to be a little helpless.

All of a sudden, the entire Celestial Dragon tribe fell into an incomparable fanaticism and yearning for bronze......
