In fact, in the final analysis, Datang's ship is still too small, compared with tens of thousands of tons, hundreds of thousands of tons of large ships in later generations, Datang's ships are only about 2,000 tons at best, which is not much larger than the patrol boats of later generations, so in terms of technology, burst pressure and rivets are enough. Vertices are updated the fastest

This is the conjecture of Li Chengqian, a half-baked scientist, yes, this is just his conjecture, this thing has no way to calculate with his ability, first, because he can't do this kind of force analysis, and second, the amount of measured data is too large, and it is impossible for him to complete it alone.

So Datang's first ironclad ship began to be built under such circumstances, and I have to say that this is really how big the heart is, how big the dream is.

……

A few days later, a certain old man did not know which nerve was wrong, or maybe he slipped into the wrong place, anyway, he somehow got mixed up with the shipbuilding site, and then a certain old man fell in love here.

Five days later, there were three more old goods.

Ten days later, the whole construction site was full of old goods.

The old goods represented by Cheng Yanjin, Wei Chigong, Chai Shao, and Qin Qiong shouted on the construction site every day, and called supervising production, but in fact, fools knew that the old goods were going to the ground to play with guns.

Just think about it, explosives must be used for explosion crimping, note that explosives are used here instead of gunpowder, explosives are far more powerful than gunpowder, so the explosion process is naturally much cooler than gunpowder.

Therefore, the veterans immediately liked this job after seeing the explosion crimping for the first time, and devoted themselves to the shipbuilding business without hesitation.

"Hey, okay, it's not there, to Lao Tzu, why don't you start yet?" Seeing that Yu Chigong had just lit a cannon battle, Cheng Yanjin was in a hurry, ran to the edge of the pit and squatted, his big eyes staring at the craftsmen who were working below.

"Cheng, Master Cheng, no, it's not a small one that doesn't make you happy, really, it's really the completion of today's project." The craftsman was about to cry when he was glared at by Lao Cheng, and said very aggrievedly.

"No, I haven't fired the cannon yet, add another cannon." Cheng Yanjin understands that shipbuilding requires craftsmanship, and in his impression, the progress of the project is naturally as fast as possible, and the so-called 'today's project is completed' is just an excuse for those unscrupulous craftsmen.

"Master Cheng, no. If you add this shot, our work today will be in vain, and it is likely that a lot of materials will be wasted. The craftsman saw that Lao Cheng was too persistent, so he had to explain: "Look at these iron plates, the villain must arrange for someone to connect all these iron plates today. ”

"I don't understand what you said about Lao Cheng, you just say, let me Lao Cheng fire another shot!" Cheng Biting Taurus's eyes were round, in his eyes, a few pieces of iron were nothing, it was a big deal to pay him a few pieces.

But if you fire a cannon later than the old lieutenant, it will be called losing face, and if you can't get it, you will be laughed at by the old guy, which is a shame and a big loss.

In the end, the craftsman was really forced by Lao Cheng to have no choice, and after pondering for a while, he said: "Master Cheng, if not, or the villain will get you some explosives, how about you find an open space and put it?" You can't blow it up again. ”

"That's fine, as long as you can fire a cannon." Cheng Lao Pifu agreed quickly.

So, not long after, a big crater was blown out of the open space not far from the construction site.

Then the vicious circle began, with the precedent of Lao Cheng setting off guns in the open space, other old goods naturally would not let go of this opportunity, and snatched the warehouse where the explosives were stored in three or two, and then ran away with the looted explosives on their backs.

As for firing guns? The ghost is putting it away, so it is natural to take it back and share it with everyone.

……

East Palace.

Li Chengqian was dealing with some of the folds that had just been delivered, and continued to make his head as big as a fight.

Outside, there was the noisy chirping of children, as well as Lao Cheng's wah-wow-wow, and of course, the laughter of his wife.

On August 15, the Mid-Autumn Festival, the day of family reunion, Lao Cheng's sons were stationed in Tianzhu, and the old man ran to the East Palace to play with his granddaughter without much trouble.

I have to say that this old man may be really old, and he would never have been able to do such a thing before.

"Grandpa, grandpa, last time you said you were going to give Langya something fun, where is the thing?" Enough trouble together, taking the opportunity to rest, Li Xiang and Langya sat on Lao Cheng's lap left and right, and the little girl raised her head and pulled Lao Cheng's curly beard and asked.

And Lao Cheng was not ambiguous, and said with a strange smile: "Hehe, Xiao Langya, fortunately, my grandfather was prepared this time, otherwise I would have been asked by you." ”

"Really? Grandpa Cheng, what's fun? Li Xiang sat on Lao Cheng's other leg, and when he heard him say that he had been prepared, he immediately became interested and asked happily.

And Langya frowned: "Grandpa lied to people, you don't have anything on you, how can there be fun." ”

"Hey, little girl, I actually look down on your grandfather, so good, let me show you today, what's fun." Cheng Lao is a playful character, and when he is older, he can't stand it anymore when he is provoked by children.

Originally, he just wanted to brag in front of his granddaughter, but he forgot about it at this time, and reached out and took out a teacup from his back waist and held it in his hand: "See, this thing is called a detonator, as long as you pull open the thing above......" Lao Cheng said while pointing to the fuse on the detonator, and then continued: "'Boom', this thing will emit a ...... louder than thunder."

Halfway through his words, Lao Cheng's face changed, because just when he was just playing, a white and tender little hand had already reached over, and he unexpectedly saw that the fuse on it was pulled out, and the specially designed fuse began to burn almost instantly.

asked for his own life, holding the two children in his arms, and holding a guy who could kill people in his hand, Lao Cheng only felt that the hairs on his back stood up, even at the most dangerous moment on the battlefield back he had never been so nervous.

In the test of life and death, Lao Cheng's potential was stimulated unlimitedly, and in the blink of an eye, he had already seen the location of everyone in the courtyard, and then saw Lao Cheng scream: "All lie down!" Then he raised his hand and threw the terrible thing in his hand towards a rockery pool in the corner of the courtyard.

Then he took the two children into his arms as fast as he could, turned and crouched down, and turned his back to the direction where the explosion was about to sound.
