The artillery blew up. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The two soldiers of the Tang Navy Division also disappeared, and everyone searched for a day, but only found a few fingers.

Xia Hongsheng locked himself in the house for a whole day.

Use self-blame.

The step is not too big, and the result is light.

I also felt that I didn't have the face to meet the soldiers of the Tang Dynasty Sailors outside.

Xia Hongsheng felt that he had harmed those two young lives.

They were in front of his eyes, with what he had designed, and they were blown down to just a few fingers.

Only Xia Hongsheng himself knows how unprofessional the drawings are, how many loopholes, how many unreasonable places, and how many imaginary elements there are.

This is simply a matter of careless human life!

"Childe, a mourning hall has been set up outside, and the soldiers of the water division hope to guard the spirits of the two strong men, Lu Liang and Zhu Da." Qi Yong stood outside the door and asked inside, "Little Douda, come for them to ask if Gongzi is allowed." ”

Xia Hongsheng opened the door, walked out of it, and said silently: "Let's go, go together." ”

The two came to the mourning hall, which was also a minimalist mourning hall. Only a few lanterns were placed on the table, and on the table were the two tablets made by the carpenter today, writing the lives of the two of them.

There were only a few clothes, a few weapons, and a few knuckles on a wooden plate.

Xia Hongsheng walked in, and everyone looked at him.

Walking to the front of the tablet, Xia Hongsheng took a deep breath and suddenly fell to his knees.

"General!" The soldiers exclaimed. Seeing that Xia Hongsheng couldn't get up, they all knelt on the ground on one knee like Xia Hongsheng.

"The soul is back! Life is brave, death is famous, you and other heroic spirits are here, prayer must be heard: follow me to the flag, chase my part, return to the Tang Dynasty, each recognize their hometown, be steamed by flesh and blood, and lead the sacrifice of the family; Don't be a ghost in a foreign land, but a soul in a foreign land. The living are mighty, and the dead are also kings. Talk about Dancheng and pay tribute to Chen sacrifices. Woohoo, alas! Fu Wei is still feasting! Xia Hong shouted loudly.

"Woohoo, alas! Fu Wei is still feasting! Behind him, a group of soldiers also had tears in their eyes, and shouted over and over again with Xia Hong's raised voice: "The soul is back......"

Xia Hongsheng did not leave, but stayed in the mourning hall, and together with those soldiers, he kept vigil for the two sacrificial sailor soldiers.

Time passed, Xia Hongsheng looked at the soldiers in the mourning hall, their faces had the sadness of losing their comrades, but there was no trace of fear. Although they knew that the artillery tests would not stop because of this, and they would have to draw lots in the future to decide who would test the artillery.

Looking at these soldiers, Xia Hongsheng's mind gradually calmed down.

There was a sound of footsteps outside the mourning hall, and then a person walked in, Xia Hongsheng raised his eyes to see, but it was the craftsman master who made projectiles, the master planner.

"Master Hou." Master Master called in a low voice.

Xia Hongsheng got up and walked out.

Master Fu bowed, and said, "Please take a step from Master Hou." ”

Xia Hongsheng nodded and walked out with him.

After walking a little farther, Master Fu said to Xia Hongsheng: "Master Hou, the old man asked someone to find the fragments of the cannon barrel that was blown up, and after careful inspection, I felt that I seemed to know the reason for the explosion of the artillery. ”

Xia Hongsheng's heart sank, and he immediately grabbed him and pulled him to the other side: "What are you talking about?!" ”

Master Fu said again: "Master Hou, after the cannon was blown up, people died, and the old people were ashamed. Those marines recovered the broken cannon barrel, the old decay was unwilling, checked together, and discussed for another day, feeling that it seemed to have found out the cause of the explosion, and they didn't know whether it should be or not, so the old decay came to play to Hou Ye and wanted to ask Hou Ye to go over and have a look. ”

"Me?" Xia Hongsheng smiled self-deprecatingly: "I will only kill people." ”

"Master Hou, although you are a genius from the sky, you are so young that you can't see this life and death!" Master Fu sighed and said to Xia Hongsheng: "If you make a new thing that has never been seen in the world, how can you do it once?" When I followed the master to learn art, the first thing I made was just a spindle, and I made it many times, and I cut my hands several times before it came to be. What's more, this thing that Hou Ye wants to do is a big thing that can ensure that the Tang Dynasty is invincible for a hundred years? Naturally, it is even more difficult. These two young offspring did not die in vain, and if this artillery is made, they will have a great merit. This is for the Tang Dynasty, and death is blind. ”

Xia Hongsheng shook his head, diverted the topic, and asked, "I don't know what you have discovered?" ”

"Master Hou, please!" Master Fu said. Xia Hongsheng nodded and went with him to the back of the shed.

The masters among the craftsmen were all here, waiting for him around the fragments of the barrels.

"What have you discovered?" After Xia Hongsheng passed, he asked directly.

Everyone looked at Master Fu, and Master Fu said: "Master Hou, we checked the barrel and felt that this problem may be in the mold of making the barrel!" ”

"Mold?" Xia Hongsheng was stunned for a moment, and immediately asked, "Master Plan, let's talk carefully!" ”

Master Fu nodded, and continued: "Master Hou, when we make cannon barrels, we dig soil and live mud on the spot, and after burning them, they make the shape of cannon barrels, and use them as molds for casting cannon barrels to make cannon barrels. But this mud mold will be damp, will be deformed, and there is sand mixed in it, so it will inevitably have trachoma. In this way, the barrel made of this mold does not look like the inside of the inner wall at first glance, but if you touch it carefully, there are many small uneven places. ”

"Yes, if you look at it, you may not be able to see it. The barrel is too long, and it seems to be very smooth at the glance, but in fact there are many small convex and concave, which is due to the fact that the mud mold is mixed with sand and has bubbles. As a result, the rifling is uneven, and the projectile turns and exits along the rifling, and if it is slightly uneven, it gets stuck in the barrel. Master Mao continued: "The projectile in front can't get out, and the gunpowder in the back burns all the gunpowder, so it is held in the barrel, so it explodes." ”

"Is there a solution?" Xia Hongsheng Q&A.

The craftsmen glanced at each other, and Master Mao said, "Master Hou, let's think about it, maybe we can try it with an iron casting mold!" ”

"Cast molds with iron?" Xia Hongsheng repeated.

Master Mao nodded and said, "Master Hou, let's think about it, the reason why we use clay to make molds on weekdays is because it is fast, and the things we make do not affect the use." But the cannon barrel seems to be unable to use mud molds. The inner wall of the barrel made of mud molds is uneven. Then change to iron to make a mold. The iron mold can be polished, and after polishing, it will not be damp and portable, and it is very light, and the barrel made of iron mold is also very smooth, and there will be no pores and trachoma. ”

Xia Hongsheng was shocked in his heart, and suddenly remembered something in his mind, so he immediately said: "Not bad, not bad!" There is one more benefit to using iron molds! After making the iron mold, you can try to make the iron mold inside the barrel hollow, and then pour cold water into the barrel while it is still hot. In this way, cooling from the inside of the barrel first creates a tension from the outside to the inside, allowing the barrel to tighten inside. This is equivalent to adding a lot of iron hoops to the barrel. This makes it stronger and has a larger charge! ”

Seeing that Xia Hongsheng agreed, the craftsmen breathed a sigh of relief, and then their spirits perked up: "Okay! Let's start making iron molds overnight! (To be continued.) )
