King An glanced at Li Rui and said, "What do you want to do with this thing for this king?" ”

Li Ruixiu hurriedly said: "Back to the prince, this kind of dagger has various shapes, and there are twelve different forms of lower officials, I hope to be able to dedicate it to the prince and benefit the soldiers of the world." Pen %Fun %Pavilion www.biquge.info"

"Oh." King An smiled sarcastically: "It's good that the horse has this heart, but I don't know what reward you want." ”

"Don't dare to have extravagant hopes, just ask the prince to reward some silver money to live."

"And how much silver does the colt want?"

Li Ruixiu was speechless, shouldn't this kind of thing be rewarded by King An, how could this prince be so direct, so he had to bite the bullet and said: "After the lower official is a criminal minister, he has no long things, and he lives entirely on the court's money, but the family has a large population and can't make ends meet, if the prince appreciates it, can he give 12,000 taels of silver to live?" ”

King An put down the drawings provided by Li Ruixiu and said: "Li Juma, Li Juma, I don't know if you are a madman This king doesn't know, but you really don't deserve to be the grandson of Li Lufeng's old fox, no wonder you have to be blindfolded, it is really empty-eyed, your dagger is indeed exquisite, this king also likes it very much, but I don't care if your other twelve daggers are still so ingenious, this king will give you a thousand taels of silver to leave the pattern of this dagger, you go, come on, send off!" ”

When King An's words fell, a small servant came up and wanted to drive Li Ruixiu away, Li Ruixiu stood up and said, "What is the reason for this, is this dagger not exquisite, this is ...... Very powerful design. Li Ruixiu almost said the fairy world, and stopped the conversation in time.

King An got a good dagger pattern in a good mood, and in the face of Li Ruixiu's struggle, he was also willing to appear in a few sarcastic sentences: "Li Daren was born in a rich and noble family, and he has never seen the suffering of the people since he was a child, not to mention the cruelty of the border war, Li Daren may not understand, on the battlefield, the weapon is naturally as long as possible, the bow and arrow are the strongest, can kill people a hundred steps away, the spear can also kill people three steps away, and the sword can have a fighting power, but the dagger of the horse is complicated to make, not to mention that it has no practical value, and can only be used for close assassination. Or divide dry food on the march, chop weeds, and encounter thick branches, and buy this one because the king really likes this thing, but it is really not necessary to say that it is used by the army. ”

Li Ruixiu was struck by lightning, he didn't expect this problem, yes, yes, the various firearms of the immortals are enough to kill people at the end of the sight, how can there be a chance to fight in close combat, and he just took out the dagger used by the immortals for granted, and felt that this thing was simple to manufacture and easy to carry and amazingly powerful, but he ignored that the immortals could kill thousands of people thousands of miles away with a simple missile, and when they needed to rely on the dagger to kill people, it was a last resort.

The subordinates quickly took a thousand taels of silver tickets, and Li Ruixiu was also sent out of the palace in despair.

He was helped by Chang'an to move forward slowly, thinking about his own weapon concept, it turned out that he was so naïve, he used to just want to become famous in one fell swoop, and after seeing the artifacts of the immortals, he didn't know anything about the battlefield, so he thought that he had created something good, and King An's temper was good enough, so he didn't beat himself out.

What should I do now, he thought of the triangular pyramid he saw again, this is something that the immortals have eliminated, but if it is added to the head of the spear, it is also a good long-range weapon.

This thing looks very ordinary, like an extended version of the head of a spear, but the lethality is extremely amazing, according to the information of the immortals, as long as it is pierced into the body, it is a blood hole, opening in three directions, and the bleeding cannot be stopped at all, it is a killing weapon. The difficulty lies in the strength of the metal, this thing is thin and long, and it is still concave on three sides, even if you don't understand the current state of Yingguo's armament, you also understand that this thing is easy to break or deform if you calculate it carefully, and it must be made of steel to make swords, so as to ensure that it can be used, and only by making it in kind can you convince Prince An.

Li Ruixiu asked Chang'an to take him to Nancheng, found the blacksmith shop on the street, and asked the blacksmith if the best material on the market for making swords could create the appearance of a triangular pyramid.

The best steel on the market, only experienced masters can practice, and to train out of steel to spend a lot of cost, need to use pig iron wrought iron ratio after high temperature steel, the most important thing is that even if the high temperature steel filling, the temperature is not high enough, the result is also semi-solid steel soft fast, no way to pour, to play into a triangular pyramid style, it is impossible, because the steel made of raw and cooked two iron pouring also needs to be vigorously beaten, so that the two kinds of steel are fully fused to form high-quality steel, and then continue to heat, forge, and repeat, Therefore, there is a saying that there are 100 steels, so steel weapons can only be made into a flat shape or a hook, and a craftsman with better skills can barely make a triangular shape, but the groove does not have to be extravagant.

Li Ruixiu was lost for a while, the design of the groove can be said to be an important reason for the amazing lethality of the triangular pyramid, now, even if he gives up the groove, the cost of the triangular pyramid is too high, and there is no way to produce a large number of them, he must solve the problem of temperature to get molten steel.

Li Ruixiu returned home and meditated, according to the immortals, the most ordinary steel also needs a high temperature of 1550 degrees Celsius to melt, and according to the information he knows, the kiln for the hottest porcelain is only 1350 degrees Celsius. So how do immortals make steel, Li Ruixiu looked for the memory in his dream, and couldn't help but scold, he had already come to make cold weapons, how to make steel, how to make steel, you also need an electric arc furnace, these immortals can't live without electricity! Eh, sin and sin, how can you blaspheme the immortals.

Li Ruixiu carefully considered how the immortals melted the steel into molten steel, in fact, in the final analysis, the temperature was not enough, the ancestors did not use any divine fire, but used some strange things, mainly to add "oxygen" to help the flame heat up, Li Ruixiu saw a steelmaking scheme that the immortals had eliminated and did not use, called converter steelmaking: place wrought iron or scrap steel at the bottom of a large open furnace, melt the pig iron into molten iron, pour it into the furnace, and at the same time quickly spray oxygen into the furnace, In this way, the pig iron will quickly burn itself, and at the same time the temperature reaches 1600 degrees Celsius, melting the wrought iron and scrap steel to form a steel night, at this time, the furnace body is rotated, and the steel night can flow out along the gap and be used to pour goods.

In the world of immortals, this method wastes energy, the purity is not easy to control, it is impossible to practice the best steel that the ancestors needed, and it also has to rotate the furnace body, in short, it has already been eliminated, but Li Ruixiu doesn't think it's better, because it doesn't use electricity!
