Now that the ten family members have become skilled, Yang Wenli actually wanted to take them out to fight bandits for a long time, which is not only an experience, but also can occupy one or several mountains in the Dabie Mountain, so as to accumulate strength and wait for the sky to change.

Of course, Yang Wenli didn't want to be the king of the mountain, kill people and goods, and be powerful. Bandits also have the advantages of bandits, in addition to robbing homes and houses, they can also farm some fields.

The mountains are not all mountains, there are also a small amount of land, and the products in the mountains are also very rich, if you know how to farm scientifically, you can feed many people.

The king of the mountain will not pay taxes to the court, and those fields are not in the list of the court, which is the real reason why Yang Wenli wants to be the king of the mountain.

Now there is a lack of a suitable weapon, as well as armor for self-defense. Originally, Yang Wenli wanted to use vines as armor, but when he hastily made a pair of them himself and tested them with a hard bow, he dispelled this idea.

In front of the two-stone strong bow and armor-piercing steel Mitsubishi arrow, the rattan armor is like paper paste, and it will be pierced with one shot, you can think about it, what are the consequences of the person wearing the rattan armor?

In fact, Yang Wenli was also too cautious, and he didn't want to think about it, what is the power of the two-stone strong bow and the stainless steel Mitsubishi armor-piercing arrow? Not to mention rattan armor, even the elite white-armored soldiers of wild boar skin can't resist it wearing three layers of armor. It's just that Yang Wenli doesn't have that condition and hasn't tried it, otherwise he might change his mind.

Yang Wenli later wanted to make plate armor, and it was carburized steel plate armor. Spears and shields have always been opposites, and the material of the shield must be stronger than that of a spear, otherwise it will not be able to defend against a spear with great kinetic energy.

It's a pity that he doesn't have that condition now, because he doesn't have iron, so he has to put it on hold for the time being. He wanted to come to the Dabie Mountains to find iron ore.

Dabie Mountain spans three provinces, the land is vast, not only iron ore, there may be other rare minerals, but the ancients have limited conditions, some have not been discovered, are waiting for him to mine!

……

"Renyu, Renju, move the cover!" Yang Wenli sang a promise to the two teenagers waiting on the side.

Yang Wenli shouted loudly when he saw that the molten iron in the crucible had reached his expected heat from the observation window.

The ancients liked this tone in everything, and Yang Wenli was not exempt from vulgarity.

After removing the lid of the furnace, Yang Wenli personally held a special pot for molten iron, scooped a pot with a spoon, and then cast the model of the shaped sand.

Today is the day of casting pig iron screws, and Yang Wenli can't do it alone, so according to the rules, the two brothers Renyu and Renju came over to help.

The cast iron screw cools easily, so it only takes half an hour to move on to the next step. Or casting, this time directly casting the bracket.

The bracket is a beam, and at the same time has the function of a nut, the steel screw and the nut are one male and one female, if the horizontal beam is fixed with a thick wooden column, it is a simple extruder, which can be used to squeeze rapeseed oil, but Yang Wenli is used to squeeze and cast steel knives, so that their texture is tight, reaching or exceeding the knives made by blacksmiths.

The working principle is like this, the molten steel is cast into a knife embryo steel mold, when the molten steel is still red-hot, together with the knife die moved to the extrusion table, the principle of human lever, but also the principle of mechanical jack to the knife embryo to exert a personal force of more than ten times or dozens of times, in the case of a steel mold outside, the knife embryo will naturally undergo physical transformation, similar to hot rolling.

The extruder is very simple, and with a precision screw, there is actually no difficulty, nothing more than wasted time.

However, although Yang Wenli's extruder is simple, it has a very large effect, which solves the problem that blacksmiths are difficult to make quick progress and the production cost of weapons is high.

The knife is actually very particular, most of the knives in ancient China do not conform to scientific laws, such as the broadsword used by the broadsword team in the Anti-Japanese War movie is not scientific.

The knife must meet several conditions, the first is the weight, it must be suitable for one-handed holding, then this weight is fixed, about three to four kilograms, if the weight is exceeded, an ordinary person can not dance a few times, and the wrist may be injured.

The weight is fixed, let's talk about the size. It is certain that the larger and thinner the knife is, and the smaller and thicker the knife size, at the same weight.

In ancient times, the knife was a weapon used in battle, and the enemy did not stand still and kill you, he would resist, so in fact, the knife was against other weapons at most.

So the question is, is the knife sharp? Or is it better to resist manufacturing? Obviously, it is the latter, and the knife that does not resist is the object of slaughter on the battlefield, and no matter how sharp it is, it is useless.

With the above conditions, in fact, the shape of a good war knife has come out. First of all, the knife should be narrow, about three fingers wide is the most suitable, and secondly, the knife should not be too long, about one meter is the most suitable, under this framework, and then stipulate the weight of 3.5 kg, it is a knife with a thick body, moderate weight, and a good fighting knife with a sharp blade.

No matter how sharp the blade is, killing people will definitely die with a knife, and people's flesh and bones are not so strong that they can't resist the heavy blows of steel.

The famous knives of cold weapons include Japanese knives, Miao knives, Tibetan knives, Nipol scimitars, etc., Yang Wenli thinks that it is not advisable, and the war knives do not need to be too sharp, and they can resist the creation of work.

Of course, the steel quality of the knife cast by Yang Wenli must be one of the best, and it is better than the steel Mitsubishi arrowhead.

……

More than ten days later, Yang Wenli held a knife that had just been cast and squeezed into shape, and he couldn't help but feel excited in his heart, this was a knife that had never appeared in history, its shape was like a knife, but it was thicker, a little shorter, and flashed with a cold and faint metallic light.

Although he has not yet started, Yang Wenli firmly believes that this is a peerless sword that will drink the blood of many enemies.

Yang Wenli believed in science and attached great importance to experiments, so he immediately equipped the first war knife with a swallowing head and a knife handle, and after a slight attack, he slashed with a single knife captured from the Jiang bandits' hole.

Sure enough, just once, a single knife was broken in response, worse than a log, although the steel knife is hard, but lacks toughness, although the wood is soft but tough enough, so the wood is difficult to cut with a knife.

"Good knives! Young Master, congratulations on forging a peerless sword. After cutting off the single knife, Yang Rentian deliberately walked up to Yang Wenli to look at the blade of the new knife in his hand, and after seeing that it was intact, he immediately praised it happily.

"Hahahaha! Rentian, you really know how to speak, this kind of knife will be your matching knife in the future, and I will name it Yang Dao. Yang Wenli was so excited that he named the knife on the spot.

In later generations, there were knives named after the region, such as Yangjiang knife, Lao Dao River knife, Tibetan knife, Miao knife, Japanese knife, etc., his knife has nothing to do with the region, it is completely his Yang Wenli alone cast knife, the quality is good, and he has no choice but to name the knife.

"Yang Dao? As the name suggests, it is a knife cast by our Yang family, a good name! Good name! Of course, Yang Rentian praised it. He can't even shoot ready-made sycophants, then he's too stupid.
