Li Yi replied excitedly, ran to the boiler in person, picked up a shovel and added coal to the furnace;

Hu San shook the blower vigorously, the charcoal fire in the furnace was flourishing, and the big wheels pushed by the connecting rod and crank were also turning faster and faster.

Suddenly, "Bang! With a loud bang, the steam sprayed out Qin Mu before he could figure out what was going on, Niu Wanshan had already pounced like lightning, "King Qin be careful!" Qin Mu was instantly thrown to the ground by him;

There was soot everywhere on the ground, choking Qin Mu's nose and making him almost suffocate.

Li Yi and the others were in a mess, like a group of dried shrimp in a frying pot, jumping around, Qian Xi reacted a little faster, shouting: "Quick, turn off the steam valve, turn it off"

"Master Qian, it's the iron pipe that has burst and can't be turned off"

"Then anneal, quick, find water, and put out the fire."

The craftsmen managed to extinguish the fire, and the steam was small.

Qin Mu propped himself up on the ground, "Poof! With a sound, he spewed out a mouthful of soot and snorted to Niu Wanshan: "Old Niu, don't you hurry up, do you want to crush this king?" ”

"Oh!" Niu Wanshan glanced at the dangerous iron lump again, convinced that there was no danger, and then got up.

Li Shi's reaction was a beat slower, and he came up with a face full of shame and asked, "King Qin, you are fine, right?" You" Li Shi originally wanted to express his concern, but when he saw that Qin Mu's face was covered with soot, he almost couldn't recognize it, so he hurriedly closed his voice, and then motioned to the guards behind him to fetch water to wash Qin Mu's face.

Li Yi and a group of craftsmen knelt on the ground, kowtowing in horror, although King Qin didn't seem to be injured, he was always frightened, and there was such a problem with the steam engine, King Qin was afraid that if the thunder was angry.

"King Qin forgives his sins!"

"King Qin spares his life"

Twenty or thirty craftsmen's heads slammed, and Qin Mu first confirmed, "Are you hurt?" ”

Li Yi and the others were stunned, but at this time, Qin Mu was not only not furious. He also asked them if they were injured, which was unimaginable, at this time, the status of craftsmen was very lowly, Li Yi and others were moved to tears, "King Qin, the grass people are fine, but their feet are burned a little." ”

"Someone, go to the doctor and give medicine to the wounded. Just go. ”

"Yes, King Qin."

Qin Mu personally checked it, a total of four people were burned, fortunately, none of them were serious, and he was relieved.

He walked briskly to the steam engine, and looked here, shook there, and felt good, and the steam engine itself was fine;

It was the craftsmen who ignored the rationality of the steam pipe. The pipe was so thin that the place where the valve was connected could not withstand the steam pressure and exploded.

Zheng Sen and the others still don't understand the reason at this time. But after seeing Qin Mu look here and shake there, he suddenly looked up to the sky and smiled, "Ha Lu haha steam engine." It's unbelievable that the steam engine was developed like this, hahaha."

Qin obviously didn't know that he was facing soot. The whole face was black and not slippery, and he looked up to the sky and smiled, looking extremely funny, Li Shi and Niu Wanshan glanced at each other, and their hearts were worried.

The two of them whispered, "You say." ”

"You say."

"You knocked people down, you say."

"You are not righteous, I pounced on people, and it should be up to you to say it."

"You two, what's wrong? What are you muttering there? Qin Mu suddenly asked.

"King Qin, wash your face first."

Qin Mu took it easy, and molded a handful of black ash from his face, and then he understood what the two of them were muttering.

He said disapprovingly: "Isn't it just that your face is dirty, what is this?" Think that at the beginning, when this king was bathing in blood, his face was gray, his body was bloody, and he hadn't taken a bath for three days, wasn't it dirtier than this? Just fetch water to wash it. ”

Hearing his words, Zheng Sen, Shi Lang, Tong Haifeng, Yang Qihuang, Shi Fu, Hong Xishan, and Ke Chenshu inexplicably had a better impression of him.

Except for Zheng Sen, the other six people are all men who have been adrift at sea for many years, if they make a fuss with a dirty face, they will definitely not be used to it, like Qin Mu's reaction, which is more in line with the true character of a man.

Qin Mu comforted Li Yi and the others a few words, and then went to wash his face.

When he came back from washing his face, he found that Li Yi and the others were still kneeling on the ground in fear, Li Yi kowtowed again and again: "The grass people have been entrusted by the King of Qin, and they have also made the King of Qin frightened, and the grass people and others deserve to die, and they deserve to die."

Qin Mu waved his sleeves and said, "This king asked you to get up, didn't you hear?" Who said that you have failed the king, you can build a steam engine in more than half a month, and the effect is not bad, it has greatly exceeded the king's expectations. Come on, all the craftsmen who participated in the development will be rewarded with twenty taels of silver each. ”

"King Qin, Caomin, and others deserve it! King Qin doesn't blame, and the grass people are already lucky."

"Don't be verbose, this king likes neat and neat people, give it to you, take it, the steam engine has been developed, but this is only the first step, you should not be satisfied, you must find ways to make it better, make it more efficient and safer;

Also, now everything is very simple, and it is not even possible to adjust the kinetic energy output of the steam engine, and now if you want to adjust it, you can only adjust the firepower, which is not possible, you come here. ”

Qin Mu walked to the steam engine, Li Yi and the others quickly got up and followed, Qin Mu pointed to the big flywheel and said: "This king tells you a principle, the small gear with the big gear, the speed of the large and small gears is different, under the condition that the cylinder workmanship remains the same, you can convert the large and small gears to adjust the wheel speed of the machine, understand?" ”

"Understood."

"About the steam engine, this king knows everything to tell you, how to improve it in the future, it's up to you to figure it out."

"Yes, King Qin, grass people and others must be contemplating it."

Only then did Qin Mu beckon to Zheng Sen and the others, and asked with a smile, "Do you see the effect of this steam engine?" ”

Zheng Sen and the others looked at each other, and finally Zheng Sen replied: "King Qin, please forgive me for being foolish, what is this steam engine used for?" ”

"What is it used for? The king tells you that this is the source of universal power, as you have just seen, and when steam enters here, it can propel this big wheel to fly;

Imagine if the wheel was the wheel of the spinning wheel, wouldn't it be possible to step on the spinning wheel without manpower? If this is the wheel of the waterwheel, then even in a calm lake, water can be pumped up to irrigate the farmland;

If this is the wheel of the carriage, then the cart can walk automatically without oxen and horses; If this is the oar of the ship, then the ship can sail without sails, and even sail faster than sails.

Hearing Qin Mu's words, Zheng Sen and the seven of them were momentarily motivated. They did see the big wheel spinning fast just now, according to Qin Mu's words, other things were secondary, and when Qin Mu described this wheel as an oar, they were most shocked.

In the Song Dynasty, there were paddle boats, but because the paddle ships had to rely on manpower to rotate the oars, this had great limitations, and it was destined that the paddle ships could not be bigger, nor could they sail for a long time, after all, manpower was limited.

But what if you had to use this steam engine to drive the wheel propellers?

"King Qin, with all due respect, what kind of steam engine really has so much strength to drive a big ship?"

Qin Mu said with a smile: "Before the artillery was manufactured, no one thought that the artillery would have so much power, this king told you, a sealed iron ball, filled with water, theoretically no matter how thick the iron ball is, as long as you heat it to a certain extent, it can make the iron ball explode." That is, the heat is incomparably large, and when fully utilized, it is nothing to drive a battleship. ”

Returning to the Autumn Dew Garden, Qin Mu first went back to the back garden to wash up, and when they came out, Zheng Sen and the others were still talking about it, today's events shocked them, and the big wheel that was spinning rapidly was still turning in their eyes, which made people a little dazzled

"Ladies and gentlemen, this king is very happy today, come, this king toasts you."

"Don't dare, I'll respect King Qin."

"Haha This king believes that one day, you will be able to command the invincible warships of Great Qin, and sweep the four seas and sweep the eight wildernesses. It's just that I don't know if the elites of the Dao are willing to be loyal to Daqin? ”

Qin Mu asked directly, and Zheng Sen and others also answered directly: "The ministers were originally loyal to the King of Qin, long live the King of Qin, long live, long live." ”

"That's good, that's good! Hahaha" Qin Mulang laughed a few times and raised his glass again. He knew in his heart that if he asked this question, Zheng Sen and the others would definitely not answer, "We are unwilling to be loyal to King Qin", which would be tantamount to looking for death;

But whether they are really willing to be loyal or not depends on their actual performance.

Qin Mu plans to keep them by his side for a period of time first, and then train them well, dripping water through stones, sooner or later they will be willing to be used by me.

PS: Today, I occasionally flipped through the calendar, and found that the beginning of autumn had passed, and I was inexplicably a little emotional, and I thought of a poem: Who pities the longest, spring dew to autumn wind. Unconsciously, the enthusiasm that burned the whole spring and summer came, and there was only a faint and gradually distant bitterness left in the sky, although I also knew that not all sweat would be rewarded, but the passage of time, the feeling of achieving nothing is still difficult to let go of all the time, I think I am still working hard, friends, vote for a monthly ticket to support it, ask for a monthly pass!
