Zhu Di stood with his hands behind his back, he looked at his son who bowed his head and shrunk his shoulders in front of him, and couldn't help but think of the day in the school field, his son held the iron rope in his hand, if that day, the direction he threw out was not towards the center of the school field but towards him, what would happen?

He couldn't help but think that outside Jizhou City, the ground where he had buried the iron rope with his own hands looked smooth and unremarkable, and no one thought that there would be anything underground, but as soon as he stepped on it, people flew into the sky.

That night, his youngest son lay in his arms and asked him, "Father, if someone buries such an iron rope at the door of our house, we don't know, what should we do?" ”

"You're going to learn what to do with Ray? Where are you going to put Reb? Zhu Di's voice was so cold that it was cold slag.

Zhu Gaoxu had a strong desire to survive, and when he heard his father's obvious displeasure, he knelt down with a puff, "Son, my son just wants to learn and follow his father to fight the Southern Army." ”

Zhu Gaoxian was still hiding behind his father, looking at the second brother who was like a rabbit in front of his father funny, and he was not afraid of the stage height when watching the play, "Second brother, you don't have a good memory, I'm afraid that you will turn around and bury your life in the courtyard of our house, and you will accidentally step on it." “

Zhu Di kicked at his second son, "I think you want to be buried at the door of my dormitory!" ”

Facts have proved that not every son dares to avoid his father's scud like Zhu Gaoxian, and not every son can get a little "hesitation" from his father like Zhu Gaoxian.

Zhu Gaoxu was kicked away.

Fortunately, in the end, it was his own, Zhu Di kicked Zhu Gaoxu's buttocks, Zhu Gaochu jumped up holding his buttocks, Zhu Di said coldly, "Since you want to help your brother receive the thirty military sticks, for the sake of you, you finally know your brother, friend and brother, and I will give you this opportunity as a father!" ”

Zhu Gaoxu burst into tears, "Dad, my son didn't say it!" ”

"Hmph, what you don't have to do, since you said it, you dare to regret it in front of your father, forty military sticks!" After Zhu Di finished speaking, he raised his feet and left.

Zhu Gaoxian was afraid of his second brother's revenge, so he hurriedly followed his father as a tail.

The pit on the school field has been filled in, and a stool has been placed, and Zhu Gaoxu is lying on the stool, enjoying the military stick.

Zhu Gaochi felt sorry for his younger brother, and he couldn't wait to take the stick in the sergeant's hand and beat it himself, and kept admonishing, "Lighter, lighter!" ”

"Shizi, we are already very light, if there is no trace of the fight, and the prince knows about it, and comes again, won't we have to suffer more crimes!"

Zhu Gaoxu cried and chirped, "Big brother, don't stop it, you let them beat me, forget it, I will die in the hands of Zhu Gaoxian's kid sooner or later, woo woo, I want to tell my mother!" ”

"You said you, your brain is not as good as him, what do you always have to provoke him all day long?" Zhu Gaochi hated that iron could not become steel, and comforted, "When you are well, you can go and make amends for the fourth brother, and get along with him well in the future. ”

"Big brother, you still help him speak, and the fourth brother is still waiting for you to vacate the position of the prince for him."

When Zhu Gaochi heard this, he stopped talking, and for a long time, he wiped a handful of sweat, "Second brother, this is your fault, even if the fourth brother said such a thing, you should rot in your stomach, if you don't say it, why did you tell me instead?" ”

Zhu Gaoxian is building a revolver, a submachine pistol with bursts.

Since the beginning of the Yuan Dynasty, the army has been equipped with firearms, which require the cooperation of two people to use, one holding a gun and one touching the mechanism.

The range of the fire gun is very short and the accuracy is low, but the smoke, fire and loud noise produced when firing still have a certain deterrent effect.

However, for the current Yan army, the southern army's firearms have simply become a joke.

The reason why Zhu Gaoxian had the idea of building a pistol was also because his father was too violent, and when he was fighting, he took the lead every time, and if it wasn't for his fate, I really don't know how many times he died.

There is still a bit of a difference between a pistol and a cannon, the parts of the pistol are too precise, and in this era, it is a bit difficult to get a caliper, mainly because the accuracy is not easy to grasp.

There are even some precision parts that are too small and the accuracy needs to be measured with a micrometer.

Zhu Gaoxian has a wooden ruler, and the scale is drawn by himself, which is the millimeter and centimeter he is used to, after all, he has used it for more than 30 years in his previous life, and he is used to it.

And he still uses a visual scale to make this ruler, and the error involved is definitely not half a star.

But, what can be done? After following his father to the battlefield, Zhu Gaoxian realized that making a pistol to defend his father had become an imminent matter.

Zhu Gaoxian is used to drawing drawings first, three views and section views, he is not afraid that the drawings will fall into the hands of people with intentions, it is useless to just make a structure, and the selection of materials and accuracy are not something that people in this era can control.

When Zhu Gaoxian took out the wooden ruler and started, he actually saw that there were two lines of scales on the wooden ruler, one of which was black that he painted with ink, and the other line was red, which was very accurate.

Zhu Gaoxian was stunned for a while, and the words "fiery eyes" popped out of his mind, could it be that this is the superpower given to him by the system?

Zhu Gaoxian was so pleasantly surprised, his heart was full of joy, if he had this "fiery eye", it would be too convenient for him to do things.

Zhu Gaoxian was about to take the knife again to make a scale, but quickly dispelled this idea, since he could see the scale on the wooden ruler, could he use these eyes to directly measure the size of the lines he drawn?

Zhu Gaoxian began to draw, although the scale still fell on the wooden ruler, but it did not prevent him from drawing, a picture was quickly drawn, and he also drew the drawings of the sub-pieces.

The underground arsenal is still thriving, and Zhu Di is ordering these people to cast parts for cannons.

Early this morning, Yongping guards Zhao Yi and Guo Liang surrendered to the city, and at the same time, Zunhua commanded Jiang Yu to send people to report that the southern army stationed in Daning had left Songting Pass and was stationed in Shahe, preparing to attack Zunhua.

At the same time, Zhu Yunwen, who was far away in Yingtianfu, was also anxious, and had already sent Geng Bingwen to lead an army of 300,000 to kill the north.

Right now, for Zhu Di, the most important thing is to build a few more cannons.

Seeing Zhu Gaoxian coming with the drawings, someone greeted him, "Fourth prince, give us another point!" ”

"What are you doing?" Zhu Gaoxian pulled the parts on the table, "Hey, isn't this a fire gun?" Where did you get it? ”

Zhu Neng walked over, "This is the blueprint of the fire gun that I finally got from the military department, but there was a mistake when rubbing, and I couldn't do it." ”
