Chen Xu got in the car and went back to the Prime Minister's Mansion, all the way still guessing that the beggars and suspicious people who were caught by the Central Guard Forbidden Army last night didn't say anything about Chen Yong and the others, if there were, it was best to find a chance to fish them out as soon as possible, but when he returned to the Prime Minister's Mansion and got off, he found that Chen Yong had come back dressed neatly.

"Master Hou!" Chen Yong bowed.

"Come with me to the backyard!" Chen Xu got out of the car and waved his hand, took Chen Yong directly to the study, and came out with a strange face after more than ten minutes, got in the car again and went out of the city with Chen Yong, and half an hour later, the carriage stopped near a small forest near the Nanshan Villa Manor.

Chen Xu repelled a group of guards and followed Chen Yong into the woods, and saw that the other ten teenagers were all there, and their clothes were all neatly dressed.

"Meet Master Hou!" A group of teenagers clasped their fists in unison.

"Where is Zhao Gao's head?" Chen Xu nodded slightly.

"Master Hou, Zhao Gao's head is here!" A teenager pulled out a black package from the grass and opened it, revealing a head with messy hair and blurred flesh, the young man kicked the head in front of Chen Xu, looking at this sparse face that could hardly be seen in any shape, Chen Xu was so disgusted that he almost vomited out the overnight meal.

The previous Zhao Gao and Chen Xu were very familiar, they were officials in the same dynasty, and Zhao Gao was still the commander of the CRRC government, and he stood next to the emperor every time he went to the court, so Zhao Gao's appearance Chen Xu could imagine it clearly with his eyes closed, but the head in front of him, Chen Xu couldn't correspond to the slightest at all, almost the same as a smashed and then rubbed on the ground, and finally used an axe to split it and ravage it repeatedly, it was a tattered blood gourd.

Holding back his nausea, Chen Xu squatted down and flipped through it with a wooden stick a few times and asked, "Are you sure he is Zhao Gao?" ”

"Hou Ye, I saw this person and a son enter the Zhao Mansion with my own eyes, and this person's appearance is no different from the costume described by Hou Ye, wearing Miao clothes, wrapped in a turban, wearing a mask, or a lame person, his appearance is extremely ugly, Hou Ye, you look at his eyes, one of them is indeed blind, the most important thing is that the thin and tall beggar named Li Gui at that time did indeed call him Zhao Gao, and Zhao Gao also recognized Li Gui, so his subordinates thought that this person must be Zhao Gao!" Chen Yong hurriedly explained.

"Well, what you said is very reasonable, is it Zhao Gao who will know the news in the palace in a few days, a royal doctor is missing, how can someone be arranged in the palace to investigate, this head is burned with fire, don't leave any traces!" Chen Xu dropped the wooden stick and stood up.

"Yes, Master Hou!" Chen Yong and a group of teenagers hugged their fists together.

"Everyone has done a good job in this matter, don't divulge any words after you go back, don't mention this matter on weekdays, and later go to the steward of the other hospital to receive a reward of two thousand yuan per person, if you want to go back to your hometown to play, I will arrange to go back with the caravan to relax......"

"Thank you, Master Hou!" A group of teenagers' cheeks flushed with surprise.

"That's it, just deal with the aftermath, don't go into the city in the last few days, it's best to hide in the Nanshan Courtyard for a while, so as not to be recognized!" Chen Xu came out of the grove after some advice.

Now that Zhao Gao is dead, it can be said that Chen Xu's mood will be soothed.

Without Zhao Gao, then the emperor would not be able to drink the Five Poisons Soul Water, and his body would not have problems so soon, and without Zhao Gao, Chen Xu would not have to worry about Zhao Gao secretly coming out to harm him all day long.

As the saying goes, good people don't live long, and disasters are in the millennium.

Zhao Gao, the bastard, has been repeated several times, and this time he is finally completely dead.

However, what made Chen Xu wonder was that Zhao Gao went to the Zhao Mansion with which son, and what did he dig up from under the laurel tree?

It's a pity that Chen Yong and the others have basically been guarding in the Nanshan Courtyard all the time, and they rarely have contact with people in the palace, so they didn't recognize which prince it was?

However, it is not too difficult to inquire about this matter, after all, Qian Niuwei, who is in charge of entering and exiting the palace, must know the people in the car, and he will know if he asks Zhou Bo another day.

Although Zhao Gao was killed, what made Chen Xu have a toothache was that Li Gui, a guy who had disappeared for a few years, would come out of thin air, and killed Zhao Gao halfway, if nothing else, the person caught in Lu Huan's mouth today is Li Gui.

According to Chen Yong, Li Gui should have recognized the identities of Chen Yong and the others at that time, otherwise he would not have said the words of letting Hou Ye take care of his parents and family.

And Li Gui disguised himself as a beggar and squatted in Zhao Mansion to guard Zhao Gao, it is estimated that it has not been a day or two, and he is so cruel and ruthless, it is estimated that this blood sea of hatred is not ordinarily deep, maybe he was wrong at the beginning, Li Gui did not assist Zhao Gao in stealing the potion to escape, but there were many things that Chen Xu did not know.

It seems that he should find an opportunity to visit the cell of the lieutenant's mansion, either to kill Li Gui in advance, or to get him out and ask the reason for it.

In the bumpy and shaking of the carriage, Chen Xu thought about the ins and outs of this matter and the aftermath in his mind, Chen Yong and the others almost went to make soy sauce once, and basically came back with a head without doing anything, knowing that Li Gui was going to kill Zhao Gao, he could not do it at all.

However, the so-called world is unpredictable, and Chen Xu does not have the ability to be a prophet.

But fortunately, the grievances and grievances that have been entangled with Zhao Gao since the beginning of the crossing have finally come to an end today, although it is not satisfactory, leaving some flaws and regrets, but Zhao Gao and Li Si, the two accomplices who finally brought down Daqin, are finally completely dead.

The wheel of history has taken the right direction, the coachman has changed to a new navigation, and Huaxia will finally roll forward along a broad road under the rule of Daqin, and will definitely not embark on the historical road known to future generations again.

And the next unknown is what Chen Xu is most interested in.

Nanshan Villa has always been a secret arms factory for Chen Xu.

The old-fashioned musket artillery is basically out of production now, a total of almost 2,000 guns have been made before and after, as well as more than 3,000 sets of trigger barrels that have been replaced, and then there are hundreds of handguns and thousands of grenades, most of which have been secretly transported back to Chen Hu and Niu Dashi by the caravan from Qinghe Town, because as the young musket team began to be deployed, some of them were originally taken to the East China Sea to deal with Huangshi Gong, and now dozens of them followed Yu Wuya and others to Japan and South Korea, and some came to Xianyang with Chen Xu, Responsible for the security of the Hou Mansion and the Nanshan Courtyard, so that the number of young musket teams in Qinghe Town has been reduced by one-third, so Chen Xu asked Chen Hu to continue to recruit some teenagers to participate in training at home, keeping the team at a stable level of five hundred.

But since the successful development of the lathe, Chen Xu has not continued to make this most honest tunnel-type firearm.

The cast barrel was not only heavy and unstable, but also very cumbersome to reload, so Chen Xu was ready to start developing pistols and rifles.

However, it is obvious that Chen Xu overestimated his own ability, and also overestimated the ability of craftsmen, to make pistols and rifles, various mechanical devices will require more precision, almost micron-level error, more than ten times higher than the current rough process of firearms and handguns, so Chen Xu had to solve the problem of measuring and supporting the production of grinding tools, and began to implement a set of more precise and strict measurement units in the experimental factory, and designed more precise lathes, grinding machines and other machines. The design of more precise vernier calipers and ruler protractors, triangles and other drawing and surveying work, the implementation of more stringent drawing methods, etc.

Generally speaking, without any scientific accumulation, there is always a trench between all beautiful imagination and reality, and every step out is extremely difficult.

It's like a bicycle, it's been four years since the project was established, but Chen Xu hasn't even seen the shadow of the bicycle, Chen Xu was still very interested in asking about it for a while, and then he didn't bother to ask, it was just to explain the mechanical transmission methods of gears and chains casually, according to the level of Daqin craftsmen in the past few years, it is normal not to do it, and it is luck to make it. I still continue to study it, but I only do it in my free time, and gradually there is no follow-up.

However, with the maturity and development of the manufacturing process in recent years, Chen Xu feels that the bicycle can still be studied, except for the manufacturing process, all the structures are very simple......

After inspecting the Nanshan Courtyard, Chen Xu's face was a little depressed.

The revolver is already a very mature thermal weapon, the barrel has rifling, and the solid bullet with customized gunpowder is used, it is these two things that make the pistol have strong power and broad application prospects, and in the late nineteenth century, it began to sweep the world, and has been almost all gun hobby and sought after.

In the American Western, the scene of those cowboys taking out their revolvers and shooting them at each other made Chen Xu remember it vividly, and he was fascinated by the revolver.

However, before the crossing, Chen Xu had never had the opportunity to get a good one in his life, but now, especially after having a lathe, Chen Xu has an unrelieved dream of a revolver.

Therefore, he vowed to get the revolver out, and then completely abandon the handcuff weighing seven or eight pounds that he hid on his body every day.

Since Chen Xu started to design and manufacture revolvers and rifles, countless drawings have been drawn one after another, and a group of craftsmen from Nanshan Villa have been explained and discussed many times, but until today, only a few barrels and simple gun bodies have been made, and the magazine wheel and firing device have not been successfully studied, in addition to the precision and complexity have increased countless times, for this more complex mechanical linkage and coordination device, it can be said that all craftsmen feel pressure, and Chen Xu himself does not understand, Just draw drawings of the appearance of the firearm, the construction of the bullet and the simple principle of operation, and the rest can only be explored by a group of craftsmen.

According to the current situation, there is still a long way to go to make a qualified revolver, and it is estimated that there will be no hope for half a year.

As for the rifle, not to mention, the barrel cannot be manufactured successfully at the moment, and the lathe cannot penetrate a solid steel rod up to one meter long, so Chen Xu had to change the method, using the casting and forging process, first create the barrel blank, and then use the lathe to trim the barrel, and finally select the qualified manufacturing rifling.

The barrel is the simplest, involving complex mechanical parts such as installing bullets, firing, and rejecting cartridge shells, which are not only complicated to the headache of Chen Xu and all the craftsmen, but also difficult to deal with the materials alone, and the materials of the firing pin and spring need to be redeveloped.

Whether it is a revolver or a rifle, in fact, the most core part should be the bullet, and for the current Daqin, making bullets is also an extremely complicated process, the cartridge case is not easy to solve, and the formula of the primer also needs to be redeveloped.

Although there are many difficulties, Chen Xu has no intention of giving up, after all, he is not fighting alone, not only has the wealth of the country, but also has three important scientific departments such as the College of Engineering, the Academy of Sciences, and the Experimental Factory as his backing, and there are thousands of craftsmen and tens of thousands of apprentices to help workers serve his scientific and technological development.

Therefore, after Chen Xu inspected the Nanshan Courtyard today, he once again lowered the requirements for craftsmen, and first manufactured a pistol rifle that could only be loaded with one round for verification, and this task could see the effect in two or three months at most.

In Chen Xu's view, the advantage of bullets is incomparable to bulk ammunition, even if it is windy and rainy, even if it is in water, it will not affect the progress of the battle, and it is a magic weapon that he will rely on to stabilize Daqin in the future, so he can only succeed and not fail.

And now that Daqin is gradually entering the industrial age, this entry-level firearm is not an insurmountable gap, but it just takes time and technological breakthrough and accumulation.
