Xiao Chuan tried this rocket in his hand, and the most difficult thing to solve the rocket was the instability problem after launch, so that later Zhao Shizhen wrote a thing called rocket tumor in the artifact spectrum to solve this rocket launch problem, but this thing was inconvenient to carry, like a firecracker, and he gave up the flexible advantage of the rocket when he took it, otherwise it seems that except for Qi Jiguang's army, no one can use the rocket alone. At that time, Ji Xiaoxin said in his new book that the target of the rocket launch assessment was eighty steps away, which shows the accuracy of the rocket.

If you don't use this rocket, or you can only make it through high-level craftsmen, you can solve the problem of flight stability, and the military craftsman in front of you called the iron pillar is one of the senior craftsmen, he is full of arrogance, arrogant personality, and bad temper, which led to the original exclusion in the thousands of households, even if he has learned exquisitely, he doesn't have much money to take, he can only eat and wait for death, and he came here, just two patents let him have a good living conditions, which was completely absent in the past.

This iron pillar had an indifferent expression, the black robe on his body was also full of stains, and his face was always the same as who owed him money, and said: "Lord, I can make this thing, and in order to maintain stability, I can use several instruments I invented to ensure accuracy."

Accuracy, this thing is the most difficult to maintain, it takes years of experience, just like this rocket, his stability, depends on the size and specification of the back of the arrow tail cartridge to fly out of a little deviation, such as the launch vehicle of later generations, the accuracy tolerance of a controller above is five microns, the operation deviation of the launch vehicle depends on the accuracy of the small controller, and the rocket in front of it relies on the accuracy of the arrow tail of the cartridge to maintain, and the current rocket stability solution is also, accuracy problem!

There are too few craftsmen who can ensure accuracy, and if you don't use craftsmen, you can only use the power of instruments, and these instruments are mostly the secrets of those craftsmen, if those eighth-level fitters after the founding of the People's Republic of China, they use files or not, everyone has their own way of making and tools, these tools you are his son, he may not pass on to you.

And now, relying on this fair patent system, the craftsmen in the fortress are all taking out their own secrets, as well as various auxiliary molds, etc., to share and promote each other.

Bang bang———— a few people who were studying the rocket heard the sound of horses' hooves in the distance, and the cavalry of more than sixty people in the middle of the king and the prince came to him around the dozen or so people in the middle.

More than a dozen knights surrounded the three of them, in the middle was a young general wearing white armor, red cloak, and an iron anchor helmet, this person was handsome and young with a resolute face, and two people on the side were also wearing a round hat and iron helmet, iron leaf armor, and a bright red cloak. The dozen or so cavalrymen next to them are also distinctly armored.

"Who are you" Xiao Chuan wondered, why did a group of knights wearing armor come, and they still looked like the elite of the Ming army?

The middle knight said: "This is Yang Yufan, this is Yang Yuan, the captain of the guard, and this is the capital of Jining Mansion."

"Meet the marshal" Xiao Chuan hurriedly bowed down, his heart was not good, how could this guy surprise check and not notify me, what should I do, I am not ready, the plan is to let the army in the city change into the clothes of the people, and then find a group of people to call Hanako to be soldiers, to pretend that his fortress is very weak, but with this Yang Yu Fan did not notice, so that Xiao Chuan did not act according to the plan at all, the other party came, or so willful, so direct, with a dozen cavalry swaggering over, are you not afraid of encountering horse thieves?

"Get up" Yang Yufan saw this young man who didn't talk like this, his eyes were full of smiles, as if he was very satisfied with the surprised expression that the other party encountered when he saw his surprise inspection.

"How do you make a surprise inspection?" Xiaochuan is strange, this guy doesn't notify himself at all, this is still a fart, it's really not according to the routine.

"Why, Qin Qianhu is still afraid that the marshal didn't inform you and didn't let you prepare early" Guan Shandao thought to himself that this guy must have spent the money on the family, and his main barracks were afraid that he didn't even have armor, he was jealous in his heart, he was in his thirties when he was promoted to Qianhu, how much suffering he suffered in the middle, how many springs and autumns he had endured, and the young man in front of him was only a weak crown is the master of Qianhu, and he was even more jealous in his heart.

And all kinds of girls with weapons on the side are all around Xiao Chuan, chattering non-stop.

When Yang Yufan saw this group of girls, he wondered in his heart and said, "What's going on?" Why is it that a group of girls are still holding weapons? ”

"These are my personal guards" After Xiao Chuan finished speaking, the group of people in front of him all laughed, and Yang Yufan also smiled helplessly, and said: "Alas, Brother Qin, it is normal to be young and romantic, you don't need to make so many excuses" He didn't care, after all, he knew Xiao Chuan's true identity, so noble, and it was normal for the family to send some beautiful maids.

"Dashuai, he is so messing around, with a group of female babies, it is simply a shame on the face of our Ming army" Guan Shan said angrily.

Yang Yufan waved his hand and said: "That's it, young and romantic, Qin Qianhu, this time I came to see the hero who defeated the Shanxi Liukou, by the way, you have a table word" He wanted to use the table word to commensurate it, and it was even more cordial.

Table words, Xiao Chuan remembered, it seems that he really doesn't have this thing, he is a Xibei goods, and it is sad that he doesn't even know anything about his own words, and said with a wry smile: "No, no, I haven't taken the table word yet, so I came out to join the army" casually recited a reason.

Yang Yufan wanted to give him a watch, but thinking of his identity in the family, he gave up this plan, and said strangely: "Xiaochuan, what are you doing" He called other names.

He pointed to the rockets, and Ogawa said, "These are rockets, just made." ”

Rocket, that Guan Shan said strangely: "You don't develop a firebolt well, what are you doing with a rocket, this thing is flying unstable, how can there be a firebolt to use, it's really a waste!" He disdains it in his heart, he is really an uninformed guy, he is really young, and he is afraid that he will not grow up mature if he suffers a few more years.

"The flight is unstable, it's mostly blacksmith waste" The iron pillar said, but his words offended Guan Shan, isn't this just a disguised way to say that Guan Shan is not good, but his character is like this, Li Muzi on the side gave him a look, and he pretended not to see it, and he looked arrogant.

"Okay, then let me see your rocket" Guan Shan said unhappily, looked at the rocket, and said: "Don't be any shoddy goods"

"That's right, Xiaochuan, this thing is troublesome to make, if you want to fly steadily, it can only be made by skilled craftsmen in the state government, Qi Shuai also used Jiangsu and Zhejiang to be skilled craftsmen to equip this thing, but it is difficult for us to find that kind of craftsman here."

The new book of the technical school says, the rocket examination school, 80 steps, flat aiming and direct shooting, if you don't hit, if you can't shoot the law, you will investigate the soldiers, if you don't have the law, you won't investigate the soldiers.

In the north and south of the river, Qi Jiguang's troops really had strict requirements for rocket launches, and most of the firearms of other armies were shoddy, not to mention more powerful rockets.

The iron pillar did not speak, holding a rocket arrow shaft in his right hand and a fire fold in his left hand, lit and then noodle the medicine jar, and lit it in the disdainful eyes of the crowd.

Especially that Guan Mountain, hum, still launching, I will see that you can't shoot for a while, I don't want to taunt you.

———— rockets flew out, streaking through the air with a long white tail of smoke.

The ———— rocket fires straight like an arrow from a crossbow.

Yang Yufan and the others opened their mouths wide in shock, especially Yang Yufan, he knew the difficulty of making this thing, and muttered: "It can be so straight, as straight as a strong crossbow" He looked at the iron pillar with arrogance in his eyes on the side, and his heart was shocked, it was really a rare skilled craftsman in the state capital! There are all of them in this little thousand houses.

Guan Shan wiped his eyes, looked at the wooden target, and said, "It's so far, the strong crossbow is just like that, my God." There was a rush of anger in his heart, and he felt ashamed of being slapped in the face.

The Iron Lord glanced at this Guan Mountain with disdain, which made him feel even more embarrassed.

And Yang Yuan too, muttered: "It's so powerful, I'm afraid it's a strong bow with one stone, and you don't need to pull the bow, you can use it right away, a sharp weapon!" ”

bump, the rocket easily pierced through the wooden target, bringing a burst of sawdust flying sideways.

Si ———— the gasping voices of the others, Yang Yufan looked at the blacksmith beside him in disbelief who looked dark and spoke angrily, and said, "You made this thing?" ”

Precisely! Tie Zhu was indifferent and didn't say anything, so Yang Yufan was a little embarrassed.

That Guan Shan was a little embarrassed, stunned in his heart, and said: "Dashuai, why don't we go to General Qin's school field to have a look" He felt that the blacksmith scene just now made him lose people, so he wanted to make this Xiaochuan also embarrassed, he expected that Xiaochuan, who spent a lot of money on the family and rockets, must not have a good barracks.
