Qin An took Liu Xia back to the Golden Fort that night.

Liu Xia didn't make trouble, and accepted the fact that she had become Qin An's wife very well-behaved.

She understood a truth, Qin An would never forget Weng Lan, and it was impossible for her to forget Qin An.

Now that Qin An has lost the woman she loves the most, but she can stay with the man she loves, what else does she have to make trouble?

The reason why I have lived in Qin City for so long is that I am waiting for Qin An?

……

Inadvertently, Qin An's happy life began like this, with four wives accompanying him every day, and the women around him were even more flowers!

However, Qin An was not immersed in the gentle township, he almost let go of all his personal affairs, went out early and returned late every day, and devoted himself to the great cause of building the city with Ling'er!

Two months later, the city of hanging swords, which has attracted everyone's attention, has finally been born!

It covers an area of almost 600 square kilometers, connecting the Kowloon Mountains to the west and the suburbs of Hanghai City to the east.

It has two layers of inner and outer walls with a height of 100 meters, the thickness of the city wall is two meters, of which the thickness of one meter and a half is a reinforced concrete structure, and the other fifty centimeters thick is an all-metal shell jointly created by Qin An and Wang Yunzhi using the ability of the Sword God!

On the city wall of the inner and outer rings, Ling'er cooperated with Wang Yunzhi to divide the metal shell into many different plates, and then installed many Mayan main control system chips between the plates.

Attached to these chips and mounted on the walls of the metal casing will be 18,000 laser cannons. Of course, at present, only the installation space has been set aside, and it will probably take some time to wait for the laser cannon to be fully produced.

These laser cannons don't have a lot of individual attack power, but they also have advantages that older ranged weapons can't have.

The laser cannon is small in size, controlled by the Mayan system, and has a super accurate strike ability, with a range of up to 300 kilometers, and each gun has a 360-degree full view. Its energy support comes from solar energy, and the firepower conversion is derived from the laser fission reaction of the metal compounds of the T-virus element, so it has a very long-lasting attack ability, and the continuous firing throughout the day does not require additional adjustments. When the substance used to make the laser disappears, it only takes a few minutes to reinstall it!

In addition, 6,000 high-caliber machine guns will be installed on the metal casing, which are also controlled by the Mayan system and fired at a maximum range of 3,000 meters, which means that under the control of Maya, a machine gun shoots 60 rounds a minute, which can shoot headshots at zombie guns 3,000 meters away!

In the interior of the double-layered wall, the construction of the return-gravity magnetic field was completed.

The so-called return-to-gravity magnetic field only works on mechanical items with anti-gravity magnetic strips installed, which can make something fly!

Therefore, the long-range and large-range offensive weapons that Ling'er had conceived in advance had appeared! It was a huge flying cake made of Qin An's alchemy, various types of metal substances, and concrete.

With a diameter of one thousand meters, a thickness of five meters, and a weight of more than 1,000 tons, 10 of them have been manufactured so far, and Ling'er has installed them with a flight power system, relying mainly on solar energy and anti-gravity, as well as a multi-ring autobiographical structure vortex system.

In short, they can be suspended hundreds of meters above Hanging Sword City under the action of the anti-gravity system, continuously absorbing solar energy, and then converting it into stored power!

When the corpses arrive, these huge and heavy flying cakes can fly up to a range of 200 kilometers. They can directly smash thousands of zombies into meat paste when they fall from the sky, so repeatedly rise and fall, even if the stored solar power can only make them rise and fall back and forth 100 times, a flying cake can kill 100,000 zombies in a short time, and 10 flying cakes can kill a million!

If it weren't for the fact that the power system was very cumbersome to manufacture, Qin An really wanted to produce hundreds of them at a time, and then let them fly all over the sky at that time, then no matter how many zombies there were, would not be able to get close to Hanging Sword City! It's a pity that the power system of the ten flying cakes took Ling'er several years to complete, not only does it require a variety of parts, but it also needs Ling'er to infuse the sword god energy! Therefore, if you want to make one more one, it is estimated that it will take at least a year.

In the interior of Hanging Sword City, there are currently five major areas.

The central city is the Golden Citadel and the Plantation Square!

A circular plot of land centered around the Golden Citadel has been reclaimed and will be mechanized to provide food for the entire city.

The multi-functional service robot template designed by Ling'er has been completed, and all the materials can be collected for 5D printing and direct production.

They look like rice cookers before the end of the world, and their size is similar to ordinary rice cookers, so Qin An named it a rice cooker robot, Ling'er despised it very much, and said a lot in the language of the Shenji clan, Qin An naturally couldn't understand what she meant.

The rice pot robot can not only farm, but also help build, clean, and organize, and is equipped with a laser weapon attack system.

To the east of Hanging Sword City is a civilian residential area, and the houses they live in have been built.

The so-called house is not an ordinary house, but a huge spaceship with a foundation!

Each spaceship can accommodate tens of thousands of people, but these spaceships are still non-flying, which is considered a half-finished product.

Ling'er will complete their power system in the future, but Ling'er said that even after completion, these spaceships will not be able to fly far and fast, because Ling'er cannot produce all the high-tech accessories that match the spaceship on Earth, and the Mayan system is already the most powerful intelligent system that Ling'er can build with the earth's resources, but she still can't complete the task of making the spaceship use efficiently.

The west of the city is a military camp, since the end of the world is full of crises, it is natural to need a national soldier system, and everyone in the Hanging Sword City needs to train in the camp in turn.

The Chengxi military camp is also the camp of the mecha warrior unit, and the 50,000 fully equipped mecha battle group has been officially established, and they are also the second legion directly managed by Qin An.

Then Nancheng is the location of the leopard legion of 50,000 female warriors, and Ling'er's first batch of beast cavalry armor has been produced.

This is a smart armor weapon with a mechanical leopard lower body and conjoined metal armor on its upper body.

The mechanical leopard is equipped with a laser gun and a miniature rocket launcher, and the weapons used by the female riders are also laser guns!

With this kind of equipment, these female soldiers will have very strong combat effectiveness, even if one person rushes into hundreds of zombies, they can kill the enemy safely and finally retreat. Compared with the MechWarriors, they have more flexible mobility and have enhanced escape capabilities, but the lethality of combat is still a bit different from that of the MechWarriors.

What is still being prepared for construction in Nancheng today is the Third Army, called the Flying Eagle.

The Flying Eagle Legion will be a group of fighters.

Because the defensive weapons of the city wall are all controlled by Maya, there is basically no need to use people to defend the city, so being able to extend to destroy zombies has naturally become the key to defense. The air-to-ground defensive attack can minimize its own losses, so Ling'er plans to use the same 5D printing method to create many air fighters.

In fact, the so-called physical printing manufacturing technology has been applied in the earth before the end of the world, but human technology is limited, and only some simple items can be printed. Rapid mass production of high-tech weapons.

Then the north of the city has now become the territory of the Treants, and they have also formed a fourth legion, called Chiba!

was able to transport these tree people from the north, but it took a lot of effort, and Lu Ya's contribution was indispensable, and the big tree that she used a rope to string and fly over was enough to swing. Wu Ma Siqi originally wanted to help, but her Tianju Sword God ability was a little annoying, although she could take outsiders back to Tianju from a distance, but the exit of Tianju was fixed, and she couldn't let the huge body of the big tree pass through, so she had to give up.

In addition, the fifth legion was returned to the city outside the city, called the Beast Soul!

Thousands of fifth-level mutant beasts were assembled, and Ling'er would armor their Beastmaster armor close to their body, so that their combat ability could be greatly improved.

In short, the organizational structure of Hanging Sword City is now very perfect.

As the commander-in-chief of the Nine Dragons Liancheng Defense System, Qin An already had absolute rights at least in the Hanging Sword City.

Weng Die was officially appointed as the city lord of Hanging Sword City, while Dong Junwei was the commander-in-chief of the five legions of Battle Armor, Leopard Print, Flying Eagle, Chiba, and Beast Soul!

Of course, the so-called commander-in-chief is actually only nominal.

Ling'er basically controlled the Battle Armor Legion, Lu Ya became the leader of the Flying Eagle Legion, Qin An has absolute influence in the Leopard Legion, and the owner of the Chiba Legion was originally the Tree Elf Queen that Qin An had not seen so far, as for the Beast Soul Legion, it can be regarded as Dong Junwei's descendant, because the captain of the Legion is Ye Liangchen, who is good at domesticating mutant beasts, this Confucian general has been following Dong Junwei since the beginning of Divine Tree City!

Qin An and Ling'er were standing in a watchtower on the east wall at this time, although there was a Mayan system that could monitor the surrounding situation around the clock, but the watchtower still had to be set up, and no one could guarantee that Maya would not have technical problems.

Looking at the big city that had been basically perfected, Qin An's heart fluctuated a little.

Ling'er's mood is not bad today, this big city can be said to have spent all her efforts, even in those years in western Tibet, she did not manufacture so many high-end scientific and technological weapons for western Tibet!

Suddenly realizing this, Ling'er was slightly stunned.

At the beginning, she originally just wanted to deal with Qin An, why did she inadvertently go all out?

Secretly glancing at Qin An beside her, Ling'er suddenly felt that her face was a little hot, and her heartbeat was actually accelerated! What is it really like?

In the past two months, Qin An and Ling'er can be said to have soaked together every day!
