Chapter 513 During the Great Qin period, the stone bridges had been developed, but the bridges were all very simple and did not have too strong structural support, so none of them were left for future generations.

When it comes to the pearl of ancient bridges, it must be the stone arch bridge, and the most representative is the Zhaozhou Bridge built in the Sui Dynasty.

Qin Xi had already thought about it, the width of this dug river channel should not be too wide, but the depth must be deep, and then build a stone arch bridge on it.

Early in the morning, Qin Xi walked around the Luoyang construction site to inspect. The previous Agunayaji is much more honest now, and even Qin Xi made him a team leader.

Agunayaji is a medium sinner, so he needs to work for more than five years, and how long he will work in ten years depends on his performance.

Since Aguna Yeji was cleaned up by Qin Xi, that group of Huns has become much more honest, and that little black house has become an absolutely terrifying existence under word of mouth.

There is also a saying among these: I am not afraid of breaking bones, my head has a big scar when I fall off the bowl, and it is better to die than to die when I enter the black house, and I would rather cut off my head than enter the black house.

For this effect, Qin Xi is still quite satisfied. This is what Qin Xi needs, not only not to kill people, but also to let these people work in a proper manner.

In the project, there are still some problems, and when the first problem is discovered, Qin Xi is much more careful.

Once there is a problem, Qin Xi doesn't care about the cost at all, and directly asks for rework and redo. Luoyang City is related to the future of Great Qin, and Qin Xi will never allow the slightest problem to arise.

In engineering, accidents can be said to be very normal, especially in ancient times, there was not too much safety equipment, which led to an accident once it happened, it was really very serious.

Therefore, Qin Xi summoned a large number of doctors, and with the imperial doctor in charge, Bai Muxue would occasionally come to help, but after Qin Xi found out, he directly pulled it away.

Qin Xi has only one requirement for these doctors, once someone has an accident, no matter who it is, even if it is a criminal, they must be the first time and do their best to treat it, as for the cost, they don't care at all, just report it.

Qin Xi's move also calmed the emotions of the criminals to a certain extent. After Qin Xi came back from inspecting for several hours, he found that Mo Ling had actually come.

"Why are you here?" Qin Xi asked. Mo Ling said: "Your Highness asked me to come here to take a look, and by the way, I will also bring His Highness's belongings." Qin Xidai nodded and said, "Sit down." After the two of them sat down, Qin Xi asked, "How is the situation on the steam engine?" ”

"It's going well." Mo Ling said: "Your Highness said that the idea of pulling a cart with a steam engine already has a clue. As for the steam engine to drive the ship, it may not be ideal. ”

"The temperature of the steam engine is too high, and it is easy to cause deformation of the ship's planks, but fortunately, there is no river test, otherwise there will be real problems." Qin Xi rolled his eyes and said, "A wooden boat is definitely not good, and at least an iron boat must be an iron ship." ”

"Iron ships? Wouldn't that sink down? No, there are so many things on the wooden ship that don't sink, and the real iron ship may work. Mo Ling figured it out all of a sudden.

Qin Xi said: "When the steam engine is on the ship, the most important thing is the oar, what kind of oars do you plan to use." ”

"Of course, it's the fan-bladed oars, the oars were originally driven by manpower, and after looking at the steam engine, you can give up manpower." Mo Ling said.

Qin Xi shook his head and said, "I have a suggestion, let's cancel all the oars on both sides of the boat and replace them with propellers. ”

"What is a propeller?" Mo Ling asked.

"Wait." Qin Xi got up and took out an iron piece bamboo dragonfly that he had made for his daughter. Qin Xi made a fuss, bent the bamboo dragonfly into the shape of the propeller in his memory, and said: "The propeller is like this, placed in the stern and driven by steam. Mo Ling held it in his hand and kept spinning, wondering if this thing was really okay?

At this time, Qin Xi brought another piece of paper, and said while drawing: "The bottom of the rotating wooden boat is flat, so it is good that the wind and waves are calm, but once the wind and waves are strong, it will be very dangerous." ”

"So, I'm going to change it and change it from a flat bottom to a pointed bottom, so that the boat will be more stable and faster." Qin Xi drew a simple drawing and handed it to Mo Ling.

After Mo Ling saw it, you were even more puzzled. This flat bottom is easier to float on the water, can this pointed bottom float?

Qin Xi said: "As long as we can solve the problem of this propeller and build this iron ship with a pointed bottom, I, Daqin, can build a powerful naval fleet that can go to the sea to catch Kun." I'm not talking about the navy in the river, I'm talking about the navy sailing on the sea. ”

"Well, as long as the Ministry of Industry has enough budget, let's try it." Mo Ling rubbed his forehead and said. The information received at this time was a bit big for Mo Ling.

I don't know if what Qin Xi said is feasible, but looking at Qin Xi's confident appearance, it is difficult to object.

Qin Xi took the spiral clamp and said to Mo Ling, "Show you this." When Mo Ling looked at Qin Xi, Qin Xi turned around with the bamboo dragonfly in both hands, and the time propeller actually flew up.

After Qin Xi picked it up, he turned in the opposite direction, and the propeller flew quickly to the ground. Mo Ling was stunned, this thing seems to be really effective!

Qin Xi broke the propeller back into the bamboo dragonfly, and with a poke of both hands, the bamboo dragonfly suddenly flew higher.

"The one I have in my hand, as long as it is made bigger, and if it can control the rotation of this thing, it can carry people up and down." Qin Xi said.

Mo Ling was stunned and asked, "How big is the oppression?" How about turning with a steam engine? Qin Xi shook his head and said, "The steam engine is too big, and the power of the steam engine can't make this thing turn to a speed that is enough to fly." Don't think about it for now, let's get the steam engine right. A trace of disappointment suddenly flashed on Mo Ling's face, and he said: "Your Highness's ideas are really imaginative, but they do not lose the truth, and I admire them." Qin Xi shook his head and said: "What is there to admire this, no matter how good I think about it, I can't make it, in the end, it still depends on you to make it, and it is you who are really worthy of admiration." ”

"Your Highness is too humble, if you don't have the ideas provided by Your Highness, we will be able to achieve nothing in our lives."

"It's difficult for this steam engine, if it weren't for His Highness's idea, and His Highness found rubber, I'm afraid I wouldn't have come up with a steam engine even if I wanted to break my head, let alone rubber." Mo Ling arched his hand and said.

Qin Xi smiled and said: "You guys, in fact, it's just that your thinking is not opened, as long as you open your mind and carefully observe things in nature, you will get some inspiration." ”

"His Royal Highness Xie taught, Mo Ling kept it in mind." Mo Ling arched his hand and said.
