In the Horse Mansion, Li Wei carefully helped An Qing to walk, and An Qing pouted, obviously a little unhappy.

During this time, Li Wei took care of her very intimately, but it was also quite annoying, he had to take care of what he could eat and what he couldn't eat, and he also took care of how many steps he took in a day, which was really more annoying than Xiaohong, a female official who could take care of everything!

"Don't go, I'm tired!"

An Qing paused and said playfully.

Li Wei hurriedly persuaded: "Take two more steps to complete the task, you hold on a little longer." ”

"Oh I don't, you've said this several times, it's a lie!"

An Qing said, shook off his hand, lifted his skirt and walked to the stone bench under the gazebo.

Xiaohong and the slaves behind him covered their mouths and snickered, and Xiaoqing also showed a smile of envy.

Li Wei was helpless and sighed: "Okay, then rest and leave." ”

Hearing that he was leaving, An Qing suddenly pursed his lips and glared at him coquettishly.

Li Wei smiled lightly, stepped forward to sit with her, and explained to her the necessity of insisting on walking.

Now Anqing has been pregnant for more than three months, and her belly has begun to bulge slightly, in order to make her give birth more smoothly, Li Wei can be said to have racked his brains, listed all the precautions that he occasionally saw in later generations, and strictly implemented them, but unfortunately Anqing, the little princess, was not very cooperative.

While they were resting and chatting, Abu suddenly came to report.

"Master, someone from the palace has passed the decree, let us prepare to receive the decree." Abu said.

Li Wei stopped nagging and looked at Abu suspiciously: "Passing the decree?" What's up? ”

He has been staying at home honestly recently, neither causing trouble nor making meritorious contributions, what did this Lao Zhu suddenly give him an order for?

Ab paused and said, "I heard that the division of the southern army has returned to Beijing, and after entering the meeting, His Majesty has lavishly rewarded you, and you have also gone out with the army, so I want to come here to this will also be rewarded." ”

In fact, Li Wei's news is not closed at all, he doesn't ask about many things, and some people report them to his guards and cronies, but Li Wei himself has no intention of asking.

Li Wei suddenly understood when he heard this, hesitated for a moment and said, "Then hurry up and let people prepare, I'll go over later." ”

"Yes!"

Abu took the command and departed.

After a while, there was an incense case in the front yard, and after the eunuch who delivered the decree arrived, Li Wei led everyone in the house to receive the decree.

Fengtian carried the emperor, and said: "The ancient philosophers set up a program of Chen Ji, rewarded meritorious, punished the guilty, and adhered to this way and the world was safe." Li Wei, the commander of the horse and the horse, practiced firearms, accompanied the army to the south, and made outstanding achievements, and used Gar Juelu, Fengjiang Duhou, 1,500 stones, and his descendants were hereditary......

The eunuch pronounced the decree loudly, and Li Wei led the crowd to bow down.

Hearing Jiang Duhou, Li Wei's heart was a little relieved, as long as he didn't return that god machine uncle to him again.

After reading the holy decree, everyone got up, and the eunuch handed the holy decree to him with an iron coupon, Li Wei took it with both hands, and casually handed the holy decree to Xiaoqing on the side and put it on the incense case, holding the tile-shaped "mortal iron coupon" in his hand and looking at it.

This small iron tile is also engraved with words, in addition to the meaning of the holy decree, there is also a line of small characters that is the most important: "I hereby swear that if you commit a capital crime, you will not be killed by two sons and one child." ”

Just like the legend, the iron coupon to avoid death, it is inevitable to rebel, these few simple words have turned the death from death into death.

"Hey......"

Li Wei held the iron coupon in one hand and sighed, it was really a person sitting at home, disaster came from heaven, and he still didn't avoid this thing.

The eunuch who delivered the decree was frightened, and reminded carefully: "Master Ma, oh no Hou Ye, you be careful, don't fall off!" ”

"What are you afraid of, it's iron and it can't be broken."

Li Wei didn't care.

"That's not going to work! Master Hou, hurry up and put it on the incense table! The eunuch urged repeatedly.

According to the rules, whether it is a holy decree or an iron coupon, after taking it, you have to respectfully put it on the incense table, but you can't throw it around, and it is even more disrespectful if you fall on the ground.

"Is this okay or not?" Li Wei asked unwillingly.

Messenger Eunuch: "......"

He really can't understand this horse master, he was ecstatic at the beginning, and he took office happily with a rotten ass, and now he is a good thing that countless people dream of, but he sighs and sighs, and he doesn't even want an iron coupon to avoid death, which is really incomprehensible!

"The king can't give it away!" The eunuch whispered.

Li Wei took the iron coupon in his hand and checked it, and the weight was not light.

The eunuch was so frightened that he hurriedly stepped forward and held his hands underneath him, for fear that he would really fall to the ground.

Seeing this, Li Weicai pursed his lips, and put the iron coupon on the prepared shelf under the nervous gaze of everyone.

Seeing that the iron coupons were finally placed, the eunuch who delivered the decree finally breathed a sigh of relief.

After the matter of sealing the marquis, he took out the edict attached by Zhu Yuanzhang: "Master Hou, Your Majesty still has a will." ”

Li Wei was stunned and muttered in a low voice: "There are so many things!" ”

said helplessly, and bowed down again with everyone.

This time, the edict was more pragmatic, Zhu Yuanzhang came up and reprimanded him first, and then assigned tasks.

Although Zhu Yuanzhang did not restore him to his official position, he did not fall behind in the same task, and he continued to supervise the construction of firearms and the affairs of the Ministry of Industry, just like the Admiral Shenji Battalion, which was in the nature of an errand.

Zhu Yuanzhang also figured it out, instead of pressing him in a certain position, it is better to treat him as a brick, where he needs to move.

Li Wei lamented the end of his idle days.

But Anqing was overjoyed when he heard the will, and shouted in surprise: "Father is wise!" ”

Li Wei turned his head to look at her in surprise.

An Qingmei glanced at him and said angrily: "Father and emperor have asked you to go out to work quickly, don't be idle at home all day!" ”

Li Wei: "......"

Hearing the undisguised dislike in An Qing's words, Li Wei felt very hurt......

It was difficult to disobey the king's fate, Li Wei could only end his vacation and go out to work honestly, but he did not let go of Anqing, and before going out, he specially told Xiaoqing and Xiaohong to take care of her, and to follow the work and rest diet set by himself.

When An Qing heard this, his little face was stretched long, and he was so angry that he stomped his feet.

In the academy, the students who were in a semi-free-range state finally came to their beloved Teacher Li first.

Fang Xiaoru also comes to the academy occasionally, but he definitely won't come to stare at it every day, while Li Wei is fishing for three days and drying nets for two days, especially after Anqing is pregnant, there are even fewer comes, if it weren't for Lu Honghe and Lu Xiu's two children staring, I'm afraid these students would have to be happy.

Li Wei also had no other good teaching methods, insisted on cramming education that combined theory with practice, and took the students to the Ordnance Bureau again, just to work and teach at the same time.

Since the hydraulic bore bed was barely usable, his energy was mainly focused on the steam engine, and with the smooth barrel of the bore, half of the sealing problem was solved, and the other half was the piston and piston rings.

The piston ring needs to be made of soft metal, mild steel, copper, etc., but it needs to be carefully polished to improve the airtightness.

There are also boilers, air ducts, throttle valves, spool valves, etc., all of which have to be carefully done, and where there is too much air leakage, the efficiency of the steam engine will be reduced.

Fortunately, he had thousands of craftsmen at his disposal, and it was enough to ask Luti to find the right skilled craftsman.

After spending some time making these things, Li Wei led the craftsmen to start assembling them by hand.

The piston is put on the piston ring, and the principle of thermal expansion and cold contraction is used to barely plug it in, and after cooling, the piston and the cylinder will become very tight, and the sealing effect is very good.

Then there are the static seals such as the air duct and the air valve, in addition to the way of vigorously performing miracles, you can also use gum leather as a filling.

A group of students watched as their teachers and craftsmen assembled these scattered objects into a behemoth that was more than a foot long, and although they did not understand what it was, they had a feeling of uncertainty.

The same is true of Luti and the other onlookers, the craftsmanship of this steam engine assembled by Li Wei must have been much more sophisticated than the original version of the Watt steam engine in history, and it makes people feel very delicate and beautiful at first glance.

After installing all the gas valve pipes, Li Wei checked it again, then wiped the sweat on his brows, waved his hand and ordered: "Ignite the boiler." ”

"Yes, Master Hou!"

The craftsman who had been standing by the boiler for a long time immediately responded.

The boiler is a simple fire tube type, which is used to make do, and with the help of the blower, the flame continues to lick the closed pot shell, and the cold water inside gradually heats up.

In the corner of the pot shell, there is a safety valve, which is hung with a heavy hammer with the principle of lever pressing, when the vapor pressure in the closed boiler reaches a certain value, the valve will be automatically relieved.

"My lord, can you really spin like a waterwheel?"

Luti asked with a twinkle in his eyes, and the other craftsmen also cast stares at him.

In fact, Li Wei had already explained the principle to them, but they still couldn't believe it, just by boiling a pot of hot water, this thing could not stop spinning like a waterwheel.

Li Wei smiled: "Of course, you just have to wait and see for a while." ”

When everyone heard this, they could only be patient and look at this big guy with anticipation.

After a long time, the water of the boiler was finally hot, and the safety valve was jacked up to exhaust the gas outward, Li Wei ordered with some excitement: "It's okay, open the throttle valve!" ”

"Yes!"

The craftsman who was guarding the side responded, put on the heat-insulating gloves he had prepared earlier, and carefully opened the throttle valve on the snorkel.

As the valve opens, high-pressure steam flows through the pipe into the cylinder, and the piston is pushed and slowly rotates through the connecting rod with a flywheel with a diameter of one and a half meters!

"It's turning, it's really starting to turn!"

Someone screamed in surprise.

Li Wei also smiled and breathed a long sigh of relief.

Although the principle of this thing is simple, it still gives him a sense of accomplishment when he actually makes it himself.

When the piston moves to the limit position, the eccentric wheel drives the slide valve connected to the slide rod to change the steam, and the piston suddenly begins to reciprocate, and the exhaust steam is spewed out, making a popping sound.

As the reciprocating motion of the piston is getting faster and faster, the sound of exhaust is also continuous, the sound of puff puff is like the old-fashioned locomotive that appears in the movie, and the roar of the machine hides the beating of the craftsmen, and the industrial age is officially opened!

Li Wei listened to this roar, only to feel that the machine noise that was annoying in the past is now so beautiful and beautiful!

When the throttle valve is fully opened, the speed of the steam engine reaches its maximum speed, and under the action of the flywheel and centrifugal governor, it rotates at a steady high speed.

It's just that because the sealing is worse after all, white steam leaks from time to time in places such as pipeline piston connecting rods, but it does not hinder the use, at most the efficiency is slightly lower, and it can be slowly improved in the future.

With the steam engine, the lathe can get rid of water power and directly use the steam engine to drive, and the machining accuracy and efficiency will be greatly improved.

The improvement of the accuracy of the lathe, in turn, can improve the process of the steam engine again, and the electric motor can also continue to improve, and most importantly, use the steam engine with a generator to generate electricity!

Without the hydraulic limitations, steam power generation can be arranged in any open space, and when the time comes, electric lights can be built, and there will be no need for dim candles and oil lamps at night!

Upstairs and downstairs, the days of electric lights and telephones are not too far away!

"Make more parts and accessories related to this machine, and transform those waterwheel-driven lathes, blowers, etc., and replace them with this steam engine."

Li Wei opened his mouth and commanded.

"Yes, don't worry!"

Luti agreed with excitement on his face.

It is not difficult for the steam engine to replace the waterwheel, which can be done by craftsmen like them.

Li Wei nodded, and then his eyes fell on those students again, because these children were too young, he didn't let them follow, but this principle still had to be explained to them clearly.

After arranging Luti, Li Wei took the students back to the academy and drew the principle of the steam engine and explained in detail the theories used in it.

The birth of the steam engine made his heart more and more hot, and he was full of longing for the convenient life brought by those technologies in later generations.

It's just that there are too many things to develop to achieve that kind of life, and he can only count on these students in front of him to come out as soon as possible and help him light up various technology trees, so that he can sit back and enjoy the results.

The students are working hard to make progress, the Ordnance Bureau is undergoing earth-shaking changes, and the court is also in turmoil.

In the evening, the little eunuch handed the recital book sorted out by the cabinet to the front of the emperor, and Zhu Yuanzhang read it in turn.

In addition to normal state affairs, a special recital book made his eyes change.

At that time, Gao Xin, the secretary of the Ministry of Rites, was one of the members of the Li Party, and under Li Wei's special instructions, the words on the national letter were particularly harsh, claiming that the Japanese would compensate 10,000 taels of silver, and if they did not give it, they would send soldiers to destroy their country.

Nearly a year has passed, and Gao Xin, the secretary of the Ministry of Rites, has already entered the earth, and the reply letter from the Japanese State was sent to Zhu Yuanzhang.

This letter is in the name of King Huailiang of the Southern Dynasty of Japan, and the wording is also very sharp, although he claims to be a minister, but the wording is very arrogant, especially for the Ming Dynasty to threaten to send troops to conscript, but also to "talk about the play, the minister is not afraid" to reply, did not take this seriously at all.

"Bastard, how dare a small country like this! If we don't dare to beat you, we can't do it! ”

Zhu Yuanzhang was furious and shot the case!
