Bang bang bang –

Wen Chen knocked lightly on the door, knocking on the door of the house opposite the mansion.

It was past midnight, and the streets were silent.

After a long time, a timid female voice came from inside, "Who's outside?" ”

Yoh?

Wen Chen raised his eyebrows, this Mo Xuyou is fat enough, before leaving, he told him that before the foot massage shop opened, he would not let him have too much contact with Lingyu, how long did it take to take the flower girl back to his residence?

"I, Wen Chen!"

"Lord Wen?!" The woman inside exclaimed, then quickened her pace and hurriedly opened the door.

After seeing Wen Chen's face, he hurriedly bowed down to apologize, "Lord Wen, it's not like you think, Mo Xuyou has been injured recently, and the slave family saw that he was inconvenient to move alone, so they came to take care of ......"

Wen Chen waved his hand casually, "Don't get in the way, Mo Xuyou hasn't slept yet, right?" ”

"Originally, I was going to rest, but since Lord Wen is here, he must be doing business first." Lingyu whispered.

Then he took Wen Chen to the bedroom where Mo Xuyou was resting.

Walking into the door, Wen Chen instantly felt a wave of heat hit, there were all kinds of iron cans and copper tripods roasted on the fire in the room, Mo Xuyou was wrapped in gauze, and he was sitting on the small bench with a bitter face.

"Lord Wen is here......"

Seeing that he didn't react, Lingyu reminded softly.

When Mo Xuyou heard this, he turned his head sharply, and when he saw Wen Chen walking in, his expression suddenly became cramped and uneasy.

"Mo Xuyou, you are brave enough to be fat......"

Wen Chen chuckled.

"Wen ...... Lord Wen, I didn't do anything with Lingyu ......"

Pulling the wound between getting up, Mo Xuyou, who was in pain, grinned.

"What do we mean is that you have set up all the boilers in the bedroom, and you are not afraid that it will blow up again and send your pair of hard-working mandarin ducks to the west?" Wen Chen glared at him.

Only then did Mo Xuyou understand that Wen Chen did not blame him for bringing Lingyu back to the house without permission, and laughed a few times, "Lord Wen knows all about it......"

Wen Chen hummed casually, the room was full of Mo Xuyou's experimental equipment, and he finally found an open space to sit down.

"Do you understand what's going on?"

Mo Xuyou scratched his head embarrassedly, "I'm not afraid of Lord Wen's jokes, before I watched the boiling water boil, I suddenly had a fantasy idea, and I felt that if I could use this natural qi urgently, I might be able to make a machine that could replace manual work." ”

"I didn't expect to toss for more than half a month, not only did I not get married, but I also made myself look like this, and now it seems that I should have failed......"

Wen Chen looked at him with a sigh, hooked the corners of his mouth slightly, took out the drawings he had drawn before from his arms and handed them over, "Look at this." ”

Mo Xuyou took the drawings suspiciously, looked at them with the help of the lights in the room, and after a while, he suddenly looked shocked, and his buttocks jumped up as if he was on fire.

Glaring at his eyes, his voice trembled, "Lord Wen, where did this drawing come from?" ”

"Slow down, your body is still well, be careful to tear the wound......"

Lingyu saw that he became so excited, and whispered on the side.

"We painted it ourselves." Wen Chen said flatly.

"Lord Wen is really a genius!"

Due to excessive excitement, Mo Xuyou's face was flushed, and he couldn't put it down while holding the drawings.

"Why didn't you think of such an exquisite structure before you went down?!"

Flywheels, cranks, valves, cylinders......

Every part of this machine is so cleverly designed that it looks simple, but none of the designs are superfluous!

"This is called a steam engine, which converts chemical energy into heat energy, and then converts it into mechanical energy, so as to promote the movement of the instrument, and with the corresponding equipment, it can indeed realize the possibility of replacing labor."

"Chemical energy...... Thermal energy...... Mechanical energy? ”

Mo Xuyou was a little dazed by these unheard of terms.

Wen Chen sighed helplessly, now it is not practical for him to explain the knowledge of physics in junior and senior high school, and when Mo Xuyou understands, the daylily is cold!

"You just need to understand that in order to make a "dead" thing move, you need energy, and these energies can be converted into each other, just like we need to eat and eat every day to have the strength to work. ”

"Oh......"

Mo Xuyou nodded as if he didn't understand, all of this sounded too novel, but for some reason, he always felt that what Wen Chen said was quite reasonable.

Normally, everyone knows that the horse-drawn cart can move, but no one has thought about why it moves.

"What you have to do now is to use the energy generated by boiling water to use levers and gears and other components to use it in actual production and daily life, and we happen to have two more interesting projects that you can try."

"I wish to hear about it in the next place."

"Steam looms and steam locomotives." Wen Chen touched his chin and said.

He remembers the most prominent inventions of the first industrial revolution on these two machines.

Silk cloth has always been the hard currency of today's society, in the past thousand years, there are countless traders who have made a fortune by relying on the cloth shop, it can be said that whoever can weave cloth in a more cost-effective way will open the door to wealth!

As for the steam locomotive, it can solve the problem of short-distance traffic to a large extent, save time and cost, and greatly improve the transportation capacity!

Mo Xuyou's eyes lit up when he heard this, he naturally understood Wen Chen's thoughts, and couldn't help but say, "Gong Wen is talented!" ”

"Please Gong Wen give someone Mo a month...... Oh no, in half a month, Mo must give Wen Gong a satisfactory answer! ”

Wen Chen nodded slightly, and then put his arm around Mo Xuyou's shoulder with a mysterious expression, "There is one more thing, you have to take the time to do it for our family." ”

"Lord Wen, please speak!"

Mo Xuyou's nerves are now in a state of high excitement, and he is eager to turn the steam engine on the drawing into a real thing, which is too tempting for a person who has been a craftsman for half his life!

"Look at this." Wen Chen said, took out another drawing from his arms and unfolded it in front of the two.

"...... this?"

Mo Xuyou looked at the strange parts on the drawing, as well as the final finished drawing, and couldn't understand what it was for a while, until he saw the word black powder, and he reacted instantly.

"This is a weapon?!"

"Clever!" Wen Chen smiled and snapped his fingers, "You can call it a revolver, or you can call it a Colt Python." ”

"How's it powering?"

"Within twenty zhang, the person wearing armor will either die or be crippled!!" Wen Chen said in a deep voice.

Hiss –

Mo Xuyou took a sharp breath of cool air, and couldn't help but tremble in his heart, if this thing was really as powerful as Wen Chen said, then it would be much better than an ordinary bow and crossbow!

Although the range of the common bow and crossbow on the battlefield today can reach 30 to 40 zhang, the power of the arrow will be greatly reduced as the distance increases, generally at a distance of more than 20 zhang, unless it hits the eyes and other vital parts, it is impossible to cause much damage to the enemy.

"Lord Wen, this thing can't be mass-produced, otherwise it will be a big deal if it spreads!"

"Nonsense!" Wen Chen patted him on the shoulder, "This step of the Colt Falcon, our family personally needs three, three hundred bullets to fill with flames, you just need to make them according to the steps and the size on the drawings, and the later debugging work will be handed over to our family!" ”

"If you also want a revolver like this for self-defense, you can also make one or two more, but remember that the drawings must not be passed on, and they will be destroyed immediately when you understand it, and every pistol you make must pass through our hands!"

"Understood!"

Mo Xuyou nodded heavily.
