At five o'clock in the morning the next day, Li Chengqian and they were already waiting at the gate of the community, and the Yumen Pass at five o'clock was already bright because it was local time, so the sky was already bright, in fact, the ancient clock was much less accurate than the atomic clock of later generations, but it was actually very accurate.

Just like the Northern Song Dynasty scientist Su Song and others created the first water transport instrument platform in history with hydraulic power as automatic mechanical operation, it is a device that combines an armillary sphere, an armillary image and a mechanical timer, and its daily timing error is reduced to a few seconds.

This error is already extremely small, and the big bell in Yumen Pass at this moment is also an experimental device, although its accuracy may be a few minutes a day, but these few minutes are enough in ancient times.

In addition, it is only an experimental timekeeping device, of course, it is not the bell that rings, it is only the staff responsible for ringing, and the real timekeeping is internal.

With the idea provided by Huo Gang, in fact, it is not difficult to develop a pendulum-type large-scale mechanical clock in the future, and the industrial city has given an approximate time, and it is expected that the first large-scale mechanical clock can be produced in the summer harvest this year.

At that time, it can be directly installed on the bell tower of several different directions reserved by Yumen Pass, and the emergence of time is actually very important for the development of a country.

Especially in some experiments, time is very important, for example, the current production of three acids and two alkalis is timed by an hourglass, but the accuracy is not so accurate because it needs to be observed by people, and it is also necessary to make different hourglasses.

At least not as accurate as a small clock.

And the development of the watch industry, the first can bring profits, the second watch industry also has a great bonus to fine finishing, there are no clocks in the world at present, as long as they are made, they can be sold, large and small can be sold.

And the profits are definitely very high.

The bell at six o'clock in the distance had not yet sounded, and Zhao Er also appeared at the door of the community, and when he saw that they were all coming, Zhao Er smiled directly and said, "Let's go, a few Lang Jun come with me." ”

Li Chengqian and the others all nodded, and after saluting, they followed Zhao Er to the outside of the city.

Bauhinia Garden is not very far from the city gate, and when they walked to the city gate, the city guards at the city gate had officially gone to work, and the city gate had already been opened.

They had noticed these machine-like guards when they entered the city before, but there was a lot of traffic at that time, so they only took a casual look.

But it was only six o'clock at the moment, and there were almost no people at the gates, but these city guards were still as straight as javelins in the daytime, and their eyes did not squint, like statues standing there.

With such a military appearance, Li Chengqian and the others who saw it were secretly numb in their hearts, they had long heard that the soldiers of the Han Dynasty were elite, but they never expected that the elite would reach such a point.

Not to mention anything else, the guards of Chang'an City in the Tang Dynasty are also elite, but even the Imperial Forest Army guarding Taiji Palace can't stand there motionless like statues for such a day, even if they change shifts every other hour.

The Imperial Forest Army also changed shifts, and it was better at several main palace gates, but some palace gates that were not usually opened, those Imperial Forest Army would never be able to do it like these city guards.

Leaving the city gate, they walked for about twenty minutes, and a huge military camp appeared in front of them, but the difference was that this military camp was made of reinforced concrete, just like the houses in the city.

The perimeter wall, which is about 3 meters high, is barely visible from the outside, and there are special watchtowers at different points on the barracks wall.

When they reached the entrance of the barracks, the two guards standing at the door stopped them directly and gave Zhao Er a strange courtesy, and then Zhao Er took out a special certificate to show the other party, and then let them in.

After entering the barracks, Zhao Er took them directly to a building first, there were already a few officers in it, from the beginning of entering this barracks, Li Chengqian and they found that this place did not seem to be the same as the city guards, all the soldiers here were wearing some black clothes, these clothes were exactly the same, this should be their military uniforms.

However, there is no armor in the entire barracks, including the guards standing guard at the entrance of the barracks, there are only weapons and no armor, it seems that this is really just a new barracks.

"Sir." The officer in the room saluted Zhao Er.

"Well, let a few of them go through the procedures for entering the camp, and start training with this batch of recruits, although their grades are not very big, but the relevant training intensity is in accordance with the regulations." Zhao Er said directly.

"Yes!"

"You guys, come here." The officer glanced at Li Chengqian and the others, and said directly.

"Yes." Li Chengqian and the others agreed, and immediately followed.

Leaving this room and entering the next room, the officer directly began to register several of them.

"Name."

"Mu Cheng."

……

"Name."

"Mu Ke."

Several people quickly registered their information, and there was no expression for the officer of their grade, but he said seriously: "You are the youngest, but what you need to complete is only the most basic recruit training, so the training intensity can definitely be completed, I hope you don't become a deserter halfway." ”

"Rest assured, sir, we will not be deserters."

"Good. From today onwards, I will teach you the first rule in the barracks, since you are soldiers, then from now on you are soldiers, and soldiers take obedience to orders as their duty! And in the barracks, what your superior officers say is military orders! I don't want to see anyone break military orders! You can question it, but only when your superiors allow you to do so. ”

"Otherwise, punishment awaits you! Also, before answering any questions in the barracks, I want you to start with, sir, or no, sir! ”

"Yes, sir!" Li Chengqian and the others were very smart, and they spoke loudly directly.

"Very well, follow me." The officer greeted them directly and led them to the next room.

Entering the room, the officer immediately began to receive them a complete set of military uniforms, bedding, washbasins for washing their faces, toothbrushes for gargling, and so on.

Especially toothbrushes, at present, there are not many toothbrushes made by Dahan, because at present, only pig hair, horse mane, tail, etc. can be made into toothbrushes, but the horse's mane is better, and the tail hair cannot be cut casually unless it is too long.

Therefore, although the difficulty of making toothbrushes is very low, the first popular use is the military camp and some high-income groups, and the whole folk has not been popularized for the time being, mainly because the raw materials are not enough, don't look at the many horses of the Han Dynasty, but if you want to make so many toothbrushes, the horsetail and horsehair required are not a small number.

And the things used for gargling are also made of coarse salt, and toothpaste is more difficult to make, so you don't need to think about it for the time being.

But for Li Chengqian and them, the toothbrush is very exquisite, at least none of these princes in the Tang Dynasty use such things, they all use silk and use their fingers dipped in green salt to gargle.

It seems that the strength of the Han skilled craftsmen is not without reason, which can be seen from these aspects.

After collecting these things for them, soon the officer called out to another soldier, "Qian Jiu!" ”

"Here!" The soldier in his thirties spoke loudly.

"Now that all seven recruits have been handed over to you, from today onwards, they will be the people of your recruit camp!"

"Yes!"

After the explanation, the officer left directly.

After the officer left, Qian Jiu turned his head to face Li Chengqian and the others, looked at Li Chengqian and the others in front of him, and Li Chengqian and the others also looked at Qian Jiu.

Qian Jiu is not tall, probably less than one meter seven, but his figure is very strong, and he has two scars on his face, all on the left, one scar is almost from the corner of the mouth to the root of the ear, and the other is on top of this one, extending from the lower part of the eye to the inside of the hair, because the other party is wearing a hat, so it is not very clear.

But these two scars made Li Chengqian and others a little flustered, mainly because this look is not a good stubble. Maybe Qian Jiu looked pretty good before, but now that he has these two scars that look extremely dangerous, the whole person instantly looks extremely hideous.

But what Li Chengqian didn't know was that although Huo Gang said that he didn't take care of them, he actually took care of them, Qian Jiu was one of the more than eighty veterans who followed Huo Gang, although he was only in charge of recruit training now, but it was because Qian Jiu had been seriously injured, and he almost picked up a life.

The scar on his face looked hideous, but it was not the most terrible, in Qian Jiu's chest, there was an arrow wound, which almost passed through the left side of his heart, and he was dead at that time, but even so, it still hurt his left lung, causing him to cough often now and not be able to exercise vigorously.

However, Qian Jiu used to be different from Zhao Er in that Qian Jiu had studied and trained recruits before, and he also liked to train recruits, so the training task here was handed over to him. However, for more than a year, Qian Jiu, who had been drinking spiritual spring water, had not had a cough for a long time, and he even felt that he had recovered.

But even if it's good, Qian Jiu is not ready to do other work, he likes his current job.

Qian Jiu is the first experiencer of non-commissioned officers in the current Huo Gang military system.
