After half a month, Qin Mu deliberately took some time to go to the workshop to check the progress of the development of the steam engine, and the workshop was headed by Li Yi, Hu San, and Qian Yi, and a total of more than 30 craftsmen were gathered. There was a smelting stove in it, steaming hot, and the sound of striking iron clanged.

Qin Mu arrived suddenly, and Li Yi and the others hurriedly stopped what they were doing and came up to pay their respects.

"Get up. Li Yi, how's it going? Qin Mu asked with a smile.

Li Yi was in his thirties, and because he was born as a craftsman, he looked very restrained, so he hurriedly replied: "Back to King Qin, all components have basically been made and are being polished." ”

"So fast?" This was much beyond Qin Mu's expectations, and in his opinion, it should take a long time.

Li Yi replied: "There are about a dozen parts, there are drawings of King Qin, grass people, etc., which are made according to the drawings, which is already slow." ”

"Okay, take this king to see."

"Yes, King Qin, please come with the grass people."

When it comes to steam engines, many people may think of behemoths like the head of the fire engine.

Of course, the steam locomotive represents its strong kinetic energy. But in fact, the steam engine is big and small, Qin Mu asked Li Yi, Hu San, and Qian Yi to develop the first steam engine is not big, and the total weight of the cylinder is only thirty catties, which is very small, and is only suitable for pushing light machinery such as textile machines.

The shape of the cylinder is square, the inside is cylindrical, divided into two pieces of casting mold, and the inside of the cylinder has been polished to a very smooth surface.

Because of the rough drawings provided by Qin Mu and the detailed explanation of the working principle of the steam engine, their progress was indeed very fast, in addition to the most important cylinder, the crank, connecting rod, slide valve, flywheel and other components have been made.

Qin Mu carefully looked at the various components, the craftsman roughly built according to his pattern, and then the precise size, there is a slide valve chamber in the upper part of the cylinder, and the steam enters the slide valve chamber first through the pipe. When the spool valve is located on the left, the left inlet is blocked, and the steam enters the cylinder from the right inlet and pushes the piston to the left.

While the piston movement drives the connecting rod to work, it also pushes the slide valve to the right, so that the steam inlet on the right is blocked by the slide valve, and the steam enters the cylinder from the left steam inlet to push the piston to the right;

The steam pushes the piston inside the cylinder to do work, and the cooled steam is introduced into the condenser through the pipe to re-condense into water. This process is repeated constantly while the steam engine is in motion.

The working principle is not complicated. There are only a few parts, the key depends on your process level, if the manufactured steam engine leaks a lot, or can not make full use of the heat energy entering the cylinder, the work efficiency will be greatly reduced.

Qin Mu is extremely looking forward to the first steam engine, but unfortunately the various components have not been polished, and polishing is a delicate job, and he can't be in a hurry. He said a few words of encouragement to Li Yi and the others, and when he left, he did not forget to instruct: "Li Yi." After the steam engine is installed, remember to tell the king, and the king must come and see for himself how the effect is. ”

"Yes, King Qin. When the time comes, the grass people will definitely go and report to the King of Qin. ”

"Well, is that two thousand taels of silver enough?"

"Enough, enough, there's still most of the surplus. After the production was completed, the total amount of silver saved, and the grass people returned it to the king of Qin. ”

"Ha Lu Ha. Let's keep it for now. Qin Mu was sure that they didn't dare to be greedy for their own silver.

Besides, as long as the development is successful, let alone two thousand taels of silver, even if it costs two hundred thousand taels, Qin Mu will not blink an eye. This is a steam engine, and with it, it will bring about a huge revolution, from the small loom to the big train and ship, it will slowly appear.

Qin Mu reluctantly left the workshop with endless obscenity, and he told Li Yi that staying there would make it difficult for the craftsmen to work with peace of mind.

When he returned to Qiulu Garden, he heard that the Zheng family had donated nine million taels of silver to him to repair the palace, and Qin Mu was even happier.

Over the years, the Zheng family has collected protection fees from passing merchant ships, and has made a profit of more than 10 million taels every year, which is not an exaggeration to say that it is a rich country.

This time, he took the initiative to donate 9 million taels, which is considered his acquaintance.

Li Shi said dissatisfiedly: "King Qin, I heard that the mansion built by Zheng Zhilong in his hometown is more luxurious than the palace, and he has more money, so he donated nine million taels, which is too cheap for him." ”

Qin Mu glared at him and said, "Don't talk nonsense, do you still want to copy the Zheng family?" If the imperial court always wants to increase its income in this way, it is self-defeating, even if no one rebels, you have copied the Zheng family, copy the Wang family, and wait for the big households to copy all the money, who do you copy? ”

"Yes, yes, the minister knows that he is wrong."

"You are the people around this king, your words and deeds are much concerned by others, you usually pay attention to what you say, in case such words come out, it will inevitably cause a storm."

"What King Qin taught me is that the ministers must be cautious in their words and deeds in the future."

Two days later, Zheng Sen, Shi Lang, Tong Haifeng, Yang Qihuang, Shi Fu, Hong Xishan, and Ke Chenshu were summoned to Ningbo, and Qin Mu set up a royal banquet in Qiulu Garden and summoned them to the banquet.

Shi Lang and the others can be said to be flattered, only Zheng Sen's demeanor is relatively calm.

The moment he saw Qin Mu, Zheng Sen couldn't help but think of the letter he received before, and now the words in that letter have been fulfilled, the order of heaven belongs to Qin, and it is indeed the mandate of heaven to return to Qin.

Thinking of this, when he paid a big salute, he didn't have much resistance in his heart.

"See King Qin, long live King Qin, long live, long live!"

Looking at the seven people who bowed down, most of them were young people in their twenties, full of heroism, Qin Mu bowed his head slightly, raised his big black sleeves and said, "Flat, sit down." ”

"King Xie Qin!"

Qin Mu signaled slightly, and Han Zanzhou immediately asked the maids to bring the prepared wine and food. Zheng Sen and the others each had a seat, sat upright, and looked at the dishes served by the maids, and couldn't help but be a little surprised, this imperial banquet was all fish, shrimp and crabs and other seafood.

Qin Mu raised his glass and said, "You don't have to be restrained, come, please drink this cup together." ”

"Respect King Qin!"

Zheng Sen and others raised their glasses together.

"You are all people who grew up on the seaside, this king specially asked people to make some seafood, let's taste it first and see if it fits the taste." After Qin Mu finished speaking, none of Zheng Sen and the others dared to move chopsticks.

"Okay, this king will come first." Qin Mu said as he picked up a peeled drunken shrimp and put it in his mouth.

Zheng Sen and the others are not afraid of poison in the dish, but this humble order, on this royal banquet, King Qin did not move the chopsticks, who dares to move the chopsticks first?

For the ministers, participating in the imperial banquet is to gain face and be hungry. After eating a royal banquet, there are very few things that actually go down.

"This king opened the foundation and established Zuo, and he was thirsty for talent, I heard that you are all talents for a while, and he is to summon you, and the purpose of this king is needless to say, that is, I hope you can serve Daqin."

When Qin Mu said this, a little eunuch outside hurriedly walked in and said to Qin Mu: "King Qin, Li Yi came to report that the steam engine had been installed. ”

"Loaded?" Qin Mujian raised his eyebrows.

"Yes, King Qin, Li Yi asked King Qin, do you want to go to the Imperial Palace?"

Qin Muha smiled, immediately got up, and said to Zheng Sen and the others: "Let's go, this king will take you to see a rare thing first, and it's not too late to drink this wine again." ”

Zheng Sen's seven people were surprised and followed Qin Mu to a workshop. But I saw that more than thirty craftsmen in the workshop were surrounding a strange device, and when they were carefully inspecting, there was a charcoal fire under a furnace next to it, and an iron boiler was erected on top of the charcoal fire, and the boiler had iron pipes sticking out and connecting to the strange device.

What is this thing that can make King Qin's banquet halfway through and rush to watch?

Qin Mu asked one of the craftsmen, "Li Yi, are you all ready?" ”

"Back to King Qin, everything is ready."

"Okay, let's try it......"

"Yes, King Qin."

Li Yi returned to the steam engine, his expression was very nervous, and his hands trembled a little.

Qin Mu comforted in a harmonious voice: "Li Yi, don't be nervous, even if you don't succeed this time, it doesn't matter, just improve slowly." ”

"Thank you, King Qin."

Li Yi still couldn't help being nervous, his hands trembled slightly and opened the gas valve of the boiler tube, for a moment, but saw that a lot of steam was spewing out of the cylinder, and under the pressure of steam, the piston in the cylinder drove the connecting rod to move, and the speed was getting faster and faster, and the connecting rod drove the crank

Zheng Sen intuitively felt that the connecting rod and crank were like people pushing a stone mill, with a big wheel outside constantly turning, and he didn't understand what was going on, and the dozen or so craftsmen couldn't help but let out a cheer.

Qin Mu was also overjoyed, and shouted loudly: "Okay, good, great, Li Yi, quickly add the fire and see if this wheel can be faster again." ”

"Yes, King Qin."

Li Yi replied excitedly, ran to the boiler in person, picked up a shovel and added coal to the furnace, while 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! Something exploded, steaming
