Of course, if you can't hear it, you can't blame Xiao Sun Quan and Lu Su for being distracted, after all, the sudden roar is still quite harsh, almost completely overpowering Lu Zhan's voice. Then, Lu Zhan pointed to Lu Chen, who was dirty, and shouted in their ears: "That's Xiao Junhou." Only then did the two of them hear clearly, and then they changed to an expression of seeing a monster, and their mouths were long enough to be stuffed with a durian.

I saw that Lu Chen opened his mouth to say something to Sun Quan and Lu Su, and then climbed into the small car with the stove, the car was very strange, it only had three wheels. Then, Sun Quan and Lu Su were so shocked that they sat on the ground, and their urine was rolling like a big river. Because...... After Lu Chen climbed into the three-wheeled car, the car, without anyone pushing or pulling a horse, actually started to move on its own.

Xiao Sun Quan's face turned pale with fright, sweat broke out on his forehead, and Lu Su trembled with a fat face, and began to scream oh oh ahhh

Lu Zhan glanced at these two buns with disdain, and said in his heart, a fool who has never seen the world is actually scared of this virtue. He had forgotten that two days before, when he saw the big iron kettle on the stove spinning hotly for the first time, he was so frightened that he fled dozens of paces with tears in his eyes.

The structure of the car and the steam engine is very strange, in the eyes of others, and in the eyes of Lu Chen himself. This is also a matter of no choice, since getting coal, Lu Chen has wanted to make a steam engine, this idea has been around for a long time, but because he has not been able to find rubber as a sealing material, he has not been able to succeed.

However, just a few days ago. He suddenly had a flash of inspiration and remembered the gadgets he had made when he was a child in his previous life. That is to poke a small hole in the egg, then fill it with a little water, lay the hole flat, light a candle underneath, and then fix the candle and the egg shell on the model boat, put it in the water, and the boat will be propelled forward by the steam spewing from the egg hole.

With this idea, Lu Chen made a large iron kettle and filled it with water. At the top, an iron pipe sticks out. The link between the iron pipe and the kettle is rotatable. The iron pipe is divided into four small tubes, which extend horizontally in four directions, and then turn ninety degrees in the same direction at the nozzle. Underneath the large iron kettle is a coal stove, when the water in the kettle is boiled by a charcoal fire. Steam is ejected from four small tubes. The iron pipe began to turn. It's not slow.

This result was made a few days ago, and then Lu Chen was very happy. Even if water vapor leaks from the connection between the water pipe and the iron kettle, it is not much. And because there is no iron ball as a bearing, the rotation of the iron pipe is very unsmooth, but it always rotates. 、

Then, Lu Chen ordered the blacksmith to make some gears overnight. The gears are linked to the rotating water pipe, and with a slight transfer, the force is transmitted. In this era, there was no chain, and there was no manufacturing technology, but Lu Chen had a cow belt, and the machine for beating rice in the countryside in later generations was not driven by a cow belt? The same was true of early tractors. So, when the cow belt was connected from the gears to the two rear wheels of the wooden tricycle, the car suddenly started moving.

This morning was Lu Chen's first test drive. Although the wooden tricycle was small, the stove behind it was boiling hot, and there was a huge and heavy iron kettle on top of it, so the car could not run fast at all. But it doesn't matter, after all, it's finally running.

I have to say that Lu Chen's idea is not creative, because, as early as the ancient Greek period, there was already this kind of similar steam equipment, but at that time it was called "double spinning ball", which was a toy thing, but it was indeed earlier than Lu Chen.

Lu Chen didn't know this, he just thought it was his creation, which made Lu Chen, who didn't understand the principle of steam mechanism construction at all, very excited.

Rumble!

It wasn't until the steam engine slowly hit the wall that Lu Chen jumped off the steam locomotive, and then commanded the riders to turn off the fire.

As a result, Lu Chen wiped his face with the towel handed over by the stone, and then walked to the entrance of the courtyard.

Sun Quan and Lu Su had already gotten up from the ground at this time, and slapped the ashes on their buttocks vigorously.

"Zhongmou?"

Lu Chen looked at the little Zhengtai with dark purple hair and gray-blue eyes and asked. In fact, there is no need to ask, this half-breed kid is Sun Quan.

"Exactly, I've seen Xiao Wenhou."

Sun Quan adjusted his mentality before giving up. However, after all, she was only a teenager, and after just two seconds of seriousness, her eyes rolled and she glanced at the iron bump in the corner of the yard, "Dare to ask Xiao Wenhou, what is that?" ”

"Oh!" Lu Chen said solemnly, "That's the Fire Dragon Chariot. ”

"Huh?" Sun Quan's mouth crooked.

"Zhong Mou doesn't know," Lu Chen was wearing black clothes, his long hair was flicked, and he put on a domineering posture, "This is a few days ago, I happened to enter the sea of flames in the demon realm, and I saw a fire-breathing demon dragon ravaging living beings, so I surrendered it and brought it back to Yanmen. Today, the iron furnace behind the car is the hellfire, which is used to drive away the fire-breathing dragon, as long as the flame is gas, the dragon will pull the car and run wildly. ”

"Uh...... But why didn't I see the dragon? ”

"How is that possible?" Lu Chen was surprised, "Anyone who is a descendant of Xuanyuan can see the Demon Dragon. You don't know that my Xuanyuan clan is a god-given clan, and they have the wisdom and vision that are different from other races. As long as I am a descendant of Xuanyuan, I can see the demon dragon. Wing width, you can see it, right? ”

Lu Zhan rolled his eyes, still coming? Yesterday, Mr. Gongtai lied to him because I cooperated with you, causing him to suspect his race for an afternoon, and then came to beat me up after figuring it out in the evening. However, today, these two goods are not deceived in vain.

"Of course!" Lu Zhan said solemnly.

Lu Chen asked Lu Su again: "Mr. Zijing is a famous businessman in Jiangdong, he must be able to see it, right?" ”

"Ahh Yes, yes. Lu Su nodded vigorously.

Lu Chen smiled again and asked Sun Quan: "Zhongmou, take a closer look, can you see it?" Look everywhere, it's red, with a flaming body burning on it, and it resembles a giant lizard-like monster. Right in front of the car, lying on the fence and sticking out my tongue tiredly. ”

"I can see, I can see." Sun Quan hurriedly said, and after speaking, his snow-white little face suddenly turned red, and he was indescribably shy.

Lu Chen hehehe Walking into the main hall, Lu Zhan was busy making tea, tea is Lu Chen's unique tea here, unlike other places, Lu Su and Sun Quan don't seem to be used to it.

"The two of them came from afar, and they were grateful. I heard that the two of you have traveled in Yanmen, I don't know what to teach? ”

Lu Chen took a sip of tea and asked.

"That...... There's no magic dragon, right? ”

Sun Quan suddenly spoke.

Lu Su's old face turned red, and he choked on a sip of tea in his throat, so he was not uncomfortable. Everyone is a smart person, and this kind of trick can naturally deceive people at first, but if you think about it carefully, there are many loopholes. But you've been tricked by someone, and you're still picking on it yourself, isn't it a shame?

Sun Quan seemed to realize this, and Xiao Zhengtai shyly clamped his legs and sneered.

"It was a steam engine, which could replace manpower and animal power, and it did not play much role on land, and it was not yet mature to make cars, so it could only be used for iron smelting and mining. However, there is a lot to be done on the water! This is specially prepared for you Jiangdong, this machine is placed on the ship, but it is a great weapon! No wind or oars can also break the waves! Are you interested? Lu Chen said with a smile. (To be continued......)
