The weapon tycoon who traveled to Daqin

"The last general pays his respects to the great general." Sima Shang saluted the army.

"Get up." Li Mu stopped thinking and waved his hand.

"General Sima, let me ask you, how did you get your 10 horses?" Li Mu first asked a key question.What is the strength of the [-] troops?

"Back to the general, this is a hundred thousand troops. One hundred thousand troops." Sima still didn't know whether he should tell the truth, because Sima still knew clearly that the composition of the one hundred thousand troops was the maimed Yunzhong Daijun. The garrison is [-], and the other [-]. I don't know where Zhao Wang put it together.All in all no fighting power.And the military discipline is extremely poor.The [-] troops were divided into two groups on the way in, and the northern one was led by Sima Shang himself.As for the one starting from Handan, because it was responsible for the supply of food and grass for the army, it would shoot and kill the Yan army who dared to attack on the road.In the beginning, the [-] Zhao army did not take the initiative to attack.But after one or two attacks happened.The retaliating Zhao Jun began to ignore military discipline.Burning and killing along the way.When Sima Shang was touring the camp yesterday, he unexpectedly found a woman from the country of Yan.It goes without saying that it's clear what's going on.Immediately, Sima Shang killed a hundred people, which played a certain role, but did not completely contain the situation.This is unknown.

"Forget it." Li Mu waved his hand and said.

Li Mu clearly knew the composition of the 10 horses.These 10 horses are not considered an army at all.It was a mob that came.Although the army in Shangdang and other places has not been mobilized.However, the north is really a big problem.If the Qin army suddenly rushed out, his own troops would be unable to resist at all.

"General, the king ordered me to take Yandu quickly. I don't know the general..." Sima Shang said.Li Mu waved his hand like a headache to stop talking.

Li Mu couldn't complete this matter at all, and everyone knew about Yandu's situation.This capital, which is close to the Hu people to the north, is extremely well built.It is difficult to attack the city.Add your own side.When Li Mu pursued the remnants of the Hu people, there were only 5 horses in total.With the increase of captured cities.There are only more than 3 people who have reached Yandu.Those reinforcements can be ignored.Li Mu's idea is to occupy the city.Digesting the land of Yan State that has already been occupied has achieved its goal.I don't know what Zhao Wang thinks.He actually wanted to attack Yandu.This is simply an impossible thing to accomplish.

"Yanhan. Do you think Li Mu dares to attack Yandu?" Yan Wangxi asked a general beside him.

"Back to the king, the general thinks, dare. This Li Mu is extraordinary. Even the tiger wolf Qin was defeated by him. I really dare not underestimate this person." Yan Han said.

"En. Then what do you think, how should this Yan capital be guarded?" Yan Wang asked again.

"The final general thinks that as long as he sticks to it, Li Mu will inevitably retreat if he is running out of food and grass," Yan Han said.

"Well, that's exactly what I mean." King Yan said happily.

"Orders. There are no orders from widows. No one is allowed to leave the city." King Yan said emphatically.

"Here." Yan Han replied.

Li Mu stood alone on a sand table, his eyes fixed on the sand table.In the north is the cavalry team of the Qin Army who is eyeing.high speed.Visit Malaysia to report.Recently, Meng Tian's army has begun to stop sweeping the tribes of the Hu people, and has begun to retreat.Wang Jian's army did not move.Just quietly stationed near the Great Wall of Yan Kingdom.There is a dynamic going south at any time.At present, there are [-] Yan troops guarding Yandu City.It is really impossible to break through Yandu.Li Mu thought about various possibilities.

If at this time, Yan State and Qin State have contact, it is very likely that Qin State will send troops.Li Mu tapped the location of the northern Qin army with his hand.This is the only force that currently poses a significant threat.If you let it go, it will be difficult to guarantee your own flank.The Qin army went south.Zhao Jun is all infantry.Not moving fast.It is easy to be rushed to death by the powerful Qin army.result.

Zhao Jun, who attacked the city wall, had begun to gain the upper hand, and Yan Jun could not recover from the defeat.At this time, a black stream suddenly appeared on Zhao Jun's flanks.Li Mu didn't dare to think about it.This situation is the most dangerous.

Attacking Yandu is not a big problem.But how to resist the Qin army in the north.That's the key.Yandu is close to the Great Wall of Yan.It was too easy for the Qin army to go south.How to solve this situation.I can only write books to King Zhao.Li Mu turned around and came to the side of the table.Soothe my mind and start writing about Zhao Jun's current situation.

At this time, Shangwen is vigorously making hydraulic machines.The first material used was wood.Two huge wooden barrels, one large and one small.After infusing the water, start compressing with bronze discs.Temporarily use human power at one end of a small wooden barrel.This is an experimental model.Whether it succeeds or not depends on the result.

Several big men pressed the wooden pole hard.under strong compression.The hydraulic machine started to move.The iron plate at one end of the vat began to slowly descend.A block of iron placed below has been placed.Shang Wen anxiously waited for the result.

time flies.The flat plate has begun to press the iron plate, and the pressed iron block has begun to deform.

"Turn harder." Shangwen shouted.

The iron block had been crushed to half its original height.Then came two thirds.

"Turn harder." Shangwen shouted.

The block of iron has been motionless.

"Stop." Shangwen yelled helplessly.

Naofumi pulled out the suppressed iron plate.Estimate the thickness, about two centimeters thick.Chen Da, who was watching from the side, looked at the pressed iron plate in surprise.Shang Wen handed it to Chen Da.You have to record the results of the experiment yourself.Not ideal.Too thick.

120 busy people

Shangwen heavily crossed the two big characters of "timber".It seems that it is obviously not acceptable to use wood as a hydraulic press.Although the iron plate can be pressed to a certain thickness to a certain extent.But this thickness still doesn't work out.

"Mr. Qin, do you think this will work? Widen and enlarge the casting mold of the iron block. The weight will be reduced. Maybe it can be pressed into a certain shape." Chen Da said.

"This." Shang Wen thought about it.

"Mr. Qin, I think this method works. In this way, the weight we require is smaller. It should be possible." A craftsman immediately thought.

Shangwen is calculating this formula at this time, seeing that everyone is so active.Then leave it to them to try it themselves, isn't it all right?

"Well, you can try this method, but I have a suggestion. According to the current situation of using wood, it cannot meet our needs. Therefore, my suggestion is that those hydraulic cylinders should still be made of iron." Shang Wen Make a suggestion of your own.The use of wood is evident.The pressure, the pressure you are under must not be able to stand.There is also sealing.Although the carpenter is very clever in making it.But after all, the airtightness is poor, at best.This wood is considered an experimental product.It is not a machine at all.

"However, I see that everyone is so interested. You can do your own research. I will write down the principle of the hydraulic press later. I will go to that area to work on the adjustment of the pneumatic hammer and the roller machine tool. Come on everyone." Shang Wen finally realized What I said was a bit too much, so I ran away quickly.

The craftsmen involved in making the hydraulic press simply ignored what Naofumi said.Instead, re-discuss the production of this hydraulic press.It was the first time they had seen such a machine.A whole block of iron can be pressed to such a degree.And the manpower and time used are also very little.This is rare.Feel very valuable.So, the craftsmen began to sit down and discuss in detail.

Shangwen didn't have that much effort.What I am responsible for is a large engineering system.If only relying on one person, it is impossible to bring Qin into a huge industrial age in this lifetime.Unless, rely on these people.These people are just busy producing and rarely get a chance to try it.Give them a chance now yourself.Also show them those schematic drawings.If you don't understand, explain a little bit.Let them do the rest.If you do everything yourself.I must be exhausted.

Thinking of this, Naofumi walked to the other side of the machine tool.Standing aside and explaining to a craftsman, attach the drive rod of the steam engine to that part.The drum is continuously rotated by the drive rod.How to make things come and so on.The craftsman nodded as if he understood.Shangwen couldn't care less.Quickly get away and leave.Draw some designs into an atlas to show those artisans.

"Mr. Qin, Mr. Qin." Chen Yong walked over with a few wooden sticks in his hand.

"Mr. Qin, this is the pencil you mentioned. I made it for you." He said and gave Shang Wen the wooden stick in his hand.

Shang Wen took the wooden stick in Chen Yong's hand and looked at it carefully.so thick.Almost the same caliber as the bullets I made myself.Also, the refill is thick.It is also much longer than a normal pencil.But think about it, this guy has probably never seen it before.never mind.Still don't be so strict.Being able to make this thing is much better than drawing with a brush every day.Besides, it is so thick that it can almost be carried around.

"Well, it's not bad." Shang Wen praised.

"However, it's still too big. Can you discuss it with the carpenters? Make it as thin as a brush and as long as it is." Shangwen said while holding a rough pencil.

"This, no problem. I thought about it at the beginning. But it is more difficult to make, so I did it this way. But in the future, this thing, yes, pencil. It can definitely be made so thin." Chen Yong said.

"Okay, I'll use it first. You go to work, and I'm going to draw some drawings." Shang Wen shook the pencil in his hand and said.

"Then, let's take my leave. Mr. Qin." Chen Yong saluted.

"Farewell." Shangwen also saluted.Then hurriedly took the pencil and left.

A hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to realize various processes.The working principle of hydraulic press.The indication is as follows.The areas of the large and small plungers are s2 and s1 respectively, and the forces acting on the plungers are f2 and f1 respectively.According to Pascal's principle, the pressure of a closed liquid is equal everywhere, that is, f2/s2=f1/s1=p; f2=f1(s2/s1).Indicates the gain effect of the hydraulic pressure. Like the mechanical gain, the force increases, but the work does not gain. Therefore, the movement distance of the large plunger is s1/s2 times the movement distance of the small plunger.Of course, Shangwen will not use those English letters that should be expressed.Shangwen directly uses A and B instead of English letters.Shangwen was afraid that the craftsmen would not understand.Deliberately mark it below.Wrote a long paragraph of notes.

"call".This thing is finally done.Naofumi threw away the pencil in his hand, and stretched his arms.Not to mention, drawing with a pencil is much faster than drawing with a brush.And not afraid to make mistakes, even if they do.You can wipe it off vigorously, or find wood chips to wipe it off.Better still use breadcrumbs.But come to this world.Shang Wen has not eaten a meal made of wheat, which is basically millet.or meat.Shangwen has become a vegetarian, and if he continues like this, he must lose weight.

"Qin...Qin..." A disastrous stuttering sound came.Shang Wen hurriedly put aside his complaints and invited Han Fei, who was stuttering to death, in.

"You don't need to talk, let's talk with a pen, so hurry up. Please come in." Shangwen completed the following actions in a series.Han Fei didn't mind Shang Wen's words either. After all, it was impolite to speak out about a person's flaws in front of one person.

"I'm here to ask Mr. Qin a few questions." Han Fei picked up a brush on the table and wrote quickly.

Shangwen looked at it.I can barely make out these words.

"You say." Shang Wen wrote.

"The book you gave, is there any other content? I found that the book is a bit incomplete." Han Fei wrote.

"Yes, yes. I'll copy it for you later." Shangwen really didn't want to write it, it was too troublesome.Just say it.

Han Fei nodded.

"Great, can you hurry up." Shangwen saw these words written on the paper.Some crashes.This guy really doesn't consider other people's feelings.I'm almost too busy.I don't have the time to copy books for you.
