After the convoy entered the Qingtang boundary for more than 100 kilometers, a neat building finally appeared at the end of the horizon.

At this time, there is only a trace of afterglow left in the sun, and the sunset is obliquely shining, reflecting the green pond in front of it in a fiery red.

Xiao Yuan stood up with a bounce of his body, and looked at the buildings in front of him: "It's finally here!" ”

Ye Han smiled, and also looked towards Qingtang City, and unexpectedly found that there was a building complex at the end of the ranch, and he unexpectedly found that Qingtang actually had no parapet!

The parapet wall is not a city wall, it can also be a layer of barbed wire, or a trench with a span of tens or even hundreds of meters, etc., in short, the parapet is the first line of defense of the city against giant insects, as long as it can play this role, it can be regarded as a parapet.

But there is nothing like it to be seen outside the Qingtang city, only a few lonely machine gun towers stand on the edge of the city, and behind the machine gun towers is the urban area.

In Ye Han's impression, the major cities in the country have long rebuilt the parapet walls, Qingtang is the largest human gathering area in the west, and the biggest feature is not the thick walls of the city?

However, the thought in my mind turned and figured it out, Qingtang is located in the west, the land is vast and sparsely populated, the natural resources are relatively poor, there are not many giant insects that can survive here, the possibility of large-scale insect swarms is very small, and small-scale insect swarms are not at all climate, and the urban defense system can completely deal with it!

Speaking of which, we have to talk about today's urban defense system, if the military's previous combat policy was to defend against the enemy's active defense, then today's policy is to defend instead of attack to preserve strength.

As early as the beginning of the insect plague, the northern capital gradually set up a number of core cities to concentrate a large number of people and avoid unnecessary losses caused by excessive population dispersion.

Since then, the architectural style of the city has taken a 180-degree turn, whether it was originally delicate and graceful or magnificent, all of them have turned to be strong and durable.

To put it simply, it is to build the walls thicker and make the windows smaller, so that insects can't dig through and get in.

Such a building is certainly not as comfortable as it was before the war, but it is better to be safe, and even the interior of the building is designed with the necessary separation, and once the swarm attacks on a large scale, each building can be turned into a bunker and fight against the swarm like a mainstay.

Even the buildings before the insect plague have been renovated in an all-round way, not to mention the buildings after the insect plague, which is a comprehensive fortress at all, so it is officially called the fortress building!

As for the folk name, there are many, and some places start from the function and directly call the turret, watchtower or fort tower; There are also places where it is called a pigeon building because of its narrowness, and there is also a tube building because of the height, and a gray building because of the color.

At present, Ye Han and the others can only see the periphery of Qingtang, all the buildings are fortress buildings, they are of the same height, similar in length and width, the surface of the unadorned concrete is rough but very strong, and the windows are as small as shooting holes.

To put it mildly, this thing is not much different from a real fortress, and you can block the street by setting up a machine gun in a random window; By mounting machine guns in several windows at the same time, crossfire can be formed.

The firepower of the fortress building is naturally more than that, generally the ground layer machine gun, the middle layer support firepower, the top layer of air defense firepower, far, medium and near matching, low, medium and high complete, it is not generally easy to deal with insect swarms.

With the scale of Qingtang, without its 1.8 million giant insects, it is impossible to break through the city, and it makes no difference whether you want a parapet or not.

There are dozens or hundreds of such cities in the country, and each city guards mankind with its strong arms.

However, such a city is only known as the infrastructure madness in China, and there are not so many building materials abroad, and there is no such rapid construction speed - according to the authoritative records of the Northern Capital, the shortest construction period from laying the foundation to the completion of a 30-story fortress building is only nine days, and the longest is only 14 days, with an average of only 12 days!

In other words, as long as the building materials are available, an engineering team can build 30 standard fortress buildings a year, and each building can accommodate 720 households and 2,880 people based on the arrangement of 24 households on each floor and 4 people per household.

Because of the large population and the shortage of materials, the distribution of the fort buildings by household was very rare, and in most cases, as in the case of the barracks, the buildings were crammed as many people as possible, and the average number of people placed in each building was not less than 4,000.

Of course, the northern capital is not to stuff people into the building and everything will be fine, so many people are crammed into a limited space, the time is short, it is nothing, the time is a long time is all kinds of contradictions and conflicts, all kinds of management systems, material supply, environmental sanitation, entertainment means and punishment measures must all keep up in time, any one of the shortcomings, will cause unpredictable consequences.

There have been problems in personnel management in major cities, and after summing up years of experience and experience, a set of effective management plans has been formed.

After thinking about it, the convoy approached Qingtang, and the road passed directly between the two fortress buildings, and the width of the road was basically the same as the width of the building.

Ye Han was surprised again here, because there were no roadblocks at the intersection, but there was a sign of the registration office on the first floor of the fortress building on the left, and several people dressed as civilians were waiting in line outside the registration office.

Seeing the convoy coming, the individual couldn't help but look over, everyone's expressions were different, some were envious, some were apprehensive, and some were yearning.

Ye Hanchong's registration office Nunuzui: "What is this place registered?" ”

Xiao Yuan smiled evilly: "It's definitely not marriage!" ”

"I didn't ask you!" Ye Han reprimanded angrily.

Gu Cheng said: "It should be the registration office for leaving the city, and after registering here, you can leave the city, and you can also change weapons and equipment from the military." ”

"It's that simple?" Ye Han was surprised, shouldn't the registration of mercenaries be strictly approved and subject to political review?

"How complicated can it be?" Gu Cheng was also surprised, "Could it be that you still have to check the eight generations of ancestors?" ”

Ye Hanxin said that being a soldier is to check the eight generations of ancestors: "Then it can't be such a child's play, right?" ”

"There must be a basic review, but it is also to check whether there is a criminal record or something." Gu Cheng said.

Ye Han was interested: "How about having a criminal record?" What if you don't? ”

"If you have a criminal record, you must be strictly reviewed, and you can pass if you do reform yourself; If you don't have a criminal record, you must be persuaded again, but if you can't persuade it, the registry office can help find a senior mercenary to take it. ”

Ye Han's whole person was shocked, wasn't he just registering a mercenary? And this kind of operation? Isn't it to relieve population pressure that people are being released from the city? Is this a deliberate attempt to train mercenaries, right?
