When Renault came to his senses, he found himself standing in a charred basin, the snow on the surrounding mountains had melted, and smoke was everywhere. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

He was naked, his phone fell to the ground, and the green indicator flashed back and forth, indicating that he had received a new message.

"Congratulations, dear player, you have successfully raised the level of Demon Spirit Power to the fifth rank!"

"As a reward for your successful advancement, a map of the Auro Continent will be issued to help you fulfill your ultimate dream of becoming the king of the world!"

What is a map for?

Renault couldn't help but complain about this system reward, and then continued to scroll down.

"However, dear players, don't forget that your initial choice was a Tech Mastery. Judging from your current level of industry, your territory is still in the age of the steam industry, and it has not yet been popularized, which is really miserable!"

Renault suddenly had a black line, and this system is really ruthless when it hurts people. He has only been in this world for more than a year, and he has already lived the life of the steam age, which is still miserable?

"So in order to speed up the pace of your industrial development, the system will continue to issue tasks to you. The task is, within a month, you need an internal combustion engine, or a replacement. ”

"Quest completion rewards for the real internal combustion engine manufacturing process. The mission fails, and you will never be able to get the manufacturing process of the internal combustion engine through the system. ”

"Please work hard and look forward to your success!"

The internal combustion engine is really difficult for some strong people.

With the current industrial level of Black Iron Town, even if the metal technology and mechanical processing technology can barely pass, but what about the fuel?

Without oil, without natural gas, it is impossible to use biogas as fuel, right?

It was only a month, and it was very difficult to build a shell. And if the mission fails, it means that if you want to build an internal combustion engine, you can't get help from the mobile app, and you can only rely on yourself to figure it out little by little.

This is not a feat that a salesman who has no mechanical foundation at all can accomplish in a short period of time.

"Ahh

Just as he was thinking about what to do, suddenly a piercing scream came.

Mia and Yushi suddenly appeared in front of him, and when they saw him naked, Mia's first reaction was to cover her eyes.

This look is really a little indecent, Renault's old face turned red, and Yuki had already gone to get a spare set of clothes for the Black Iron Army and put it beside him.

Dressed neatly, Renault remembered the fight with Norman just now.

"Brother Norman said he threw in the towel. Mia said with a red face, "But he wants to see you, so you're going now?"

For Norman, although there was an inexplicable fight, Renault had no dislike for him.

The culprit, Lyle, had just been burned to ashes in the flames of the mountain, and Norman, who had gone to save Mia, didn't even look at him.

It's not that Norman is cold-blooded, it's in his consciousness that Lyle deserves it.

"You ......"

Looking at the smiling Renault, Norman had thought of a lot of things, but suddenly didn't know where to start.

He felt that the two should be heroes sympathizing with each other, like friends who hadn't seen each other for ten years reuniting, and punching each other in the chest. But suddenly thought that he and Renault had just met today, and they didn't even say a word, and if this punch caused Renault's misunderstanding, and then put the black shadow out, the joke would be bigger.

"Forget it," Norman shook his head, commenting that Renault was not a complete reckless man, at least it looked like a good match for Mia, "Take good care of Mia, your majesty don't worry, I'll explain everything to him when I get back." ”

"Thank you. ”

"It's nothing, it's Lyle's fault this time. Norman said.

"Brother, are you finally going back to the royal capital?"

"Well, actually, I would like to play for a few more years," Norman sighed helplessly, "but His Majesty Father has urged me many times, and if I don't go back, I'm afraid he will be really unhappy." ”

After saying that, Norman was about to beckon his subordinates to leave, and before leaving, he looked meaningfully at Yushi behind Renault, and finally said to Renault slowly: "Take care of yourself, I believe it won't be long before we will meet in the royal capital soon." ”

Renault didn't understand what he meant, and Norman didn't explain much, waved his hand at his subordinates, and soon disappeared into the mountains.

What a strange person.

After Norman left, when he thought of the food problem in Tuk City and the system task he received today, Renault was not in the mood to look at the scenery at all.

He asked Yushi to take him back to Black Iron Town quickly, and every minute and every second from now on would be incomparably precious and urgent.

Renault locked himself in his room and searched through a thousand degrees to find out countless information about the internal combustion engine.

The so-called internal combustion engine usually refers to a machine that uses the heat generated by fuel to do work, and diesel engines, gasoline engines, and even aircraft engines all belong to this category.

But without exception, fuels that burn quickly and then release heat are required.

Oil is undoubtedly the best choice, and it can be said that the internal combustion engine is a machine specially designed on the basis of oil.

Renault rummaged through almost all the sources, and finally regretted to find that there was really nothing in the world that could replace oil.

The closest ones are biogas and animal oil.

Biogas is easy to make, digging a pond to get some farm manure and weeds, but there is no air compressor, and it is a big trouble to collect and store it.

I had to try animal oil instead.

With the general direction, Renault chose the simplest two-stroke diesel engine as a reference, and began to draw drawings, with the help of a thousand degree search, a simple shell and parts of the drawings were quickly drawn on paper.

The casing and cylinder are made of cast iron, the piston head is aluminum, and as for the connecting rod, crankshaft and piston ring, Renault directly smelts some high-strength aluminum alloy to process.

Anyway, just like when making a steam engine, as long as you can make a moving prototype, even if it is successful, it doesn't really need to be put into use, so you don't need to be too particular about the materials.

The intricate drawings were handed over to the blacksmith Ferrier, and they were immediately executed, and the machine shop rushed to produce them overnight, and finally made what Renault wanted three days later.

The next step was assembly, this time with Renault taking matters into his own hands, with various parts and seals mounted to the casing, all the screws fastened, a pot of lard heated into a clear liquid connected to the conduit, and a small steam engine used as a starting device.

The first self-produced internal combustion engine in Black Iron Town was completed, and because it was fueled by lard, Renault simply named it "Wild Boar".

Open the steam valve, the steam engine began to rotate at low speed, the lard dripped into the boar's cylinder little by little through the conduit, and the piston kept reciprocating in the cylinder, compressing the air and generating up to 600 degrees of heat, and the lard began to burn at high temperatures.

Puff puff puff -

There was a puff of black smoke coming out of the exhaust pipe, but just like when I was a kid when I saw a failed tractor start, Renault's internal combustion engine made only a dull sound before it went out completely.

The first attempt, failed. (To be continued.) )
