Chapter 443: Expansion Base

It is not easy to expand in the zombie apocalypse.

The easy thing is to simply annex all the hostile forces on the road of expansion and bring other security bases under its own control.

Most bases in previous lives adopted this approach.

The hard part is to expel the zombies too!

But the zombies are killing endlessly, and the dead zombies will become nourishment for other zombies.

If you just kill the zombies within your own territory, zombies from other places will still be attracted and spread across the vast and poorly defended territory.

Therefore, if you want to completely drive out the zombies, you must build a safe base and include all the land within the sphere of influence within the walls!

This places extremely high demands on a force's infrastructure capabilities.

Moreover, infrastructure requires a lot of materials, and ordinary materials before the end of the world cannot stop zombie attacks at all.

Then you can only exchange materials from the God-given space.

And this requires a massive amount of points!

Nowadays, Blue Star has expanded a hundred times. If we want to build a wall along the border of China, which has become a hundred times larger, it will consume an incredible amount of materials!

But zombies will gain the ability to fly when they reach seven stars. Hard walls alone cannot stop zombie invasion.

Therefore, if you want to keep out all the zombies, you need to cover the entire sky!

This matter seems unsolvable, but it is not.

Among the technologies exchanged from the God-given space, there is a black technology, which is the double-layered semicircular bubble film shield that wraps the entire Fish-Man Island.

Although this shield is not absolutely forbidden to enter, it can also play a protective role.

But if used on land, it doesn't seem to be very useful.

Fortunately, among the scientific and technological achievements they exchanged, there are the application of bubble shields on land and improvement plans.

The improved shield still cannot completely isolate zombies, but if a creature tries to pass through the shield, the control center will be alerted.

Moreover, the invaded area will be displayed on the console, making it easier for humans to send troops to stop it.

In addition, Ao Xin, who lived into the second divine gift period in his previous life, knew that the second divine gift was the period of practicing spiritual pressure, and the items that appeared in the divine gift space were also related to the God of Death.

Among them are the murderous stone and the construction method of Seireitei's outer wall.

At that time, upgrading the external walls with murderous stone can raise a spiritual protection shield that is invisible to the naked eye based on the original coating!

The spiritual protective shield can keep most enemies out.

Although this also requires a large amount of murderous stones and countless infrastructure teams working for an unknown amount of time to complete the upgrade of the original exterior wall.

But it is a method after all.

Although those forces in the previous life did not choose to build this laborious and expensive wall.

But Ao Xin believes that it appears in the God's Gift space, and both God's Gifts have similar upgradable technologies, it is definitely not useless!

There are huge amounts of zombie viruses in the air in the world today.

If there were no zombies to suck up the viruses in a space and use their ominous aura to prevent the invasion of external viruses, then humans would not be able to have a true pure land.

The reason why zombie corpses cannot be disposed of by incineration is because zombie viruses will be catalyzed at extremely high temperatures and spread in the air, making the zombie viruses in the air more concentrated.

If all the zombies in the world were burned, the concentration of zombie viruses in the air at that time would be enough to infect all humans in the world!

Even if it is buried, it will not work. The zombie virus will contaminate the land and infect the water source, causing no worse harm than burning.

Therefore, at present, all humans can do when facing zombies is to kill them, throw the corpses out, and then expel them.

Although today's human strength continues to improve, the body has been able to resist this level of zombie viruses in the air.

But newborns cannot resist.

Without the emergence of fresh blood, humans will eventually become extinct even if they are not killed by zombies!

However, Ao Xin vaguely noticed it from the similar technologies appearing in these two divine gifts.

Perhaps, the establishment of the wall is the foundation for building a pure land in the future!

He didn't know if his guess was correct, but whether it was correct or not, it was worth a try!

Even if the zombie virus in the air cannot be completely eliminated in the future, at least there must be a city without zombies!

He told everyone present his plan, and everyone was shocked by his ambition.

"Boss, do you want to surround the entire Bian City?"

Meng Kui asked aloud.

Ao Xin said:

"Of course, the first step is to build a defensive wall around Bian City, the second step is to build a defensive wall around Yuzhou, and finally I want to include the whole of China!"

"I know it's hard, but let's take it one step at a time."

"In addition to the walls that have been built at the Yanhuang Base, there are four layers of protection. If the zombies become too strong in the future for us to resist, the four layers of walls can also be regarded as four layers of barriers, giving humans time to retreat and develop."

"Everyone should discuss the construction route, manpower allocation, quantity of materials required, and estimated construction time."

The start of every project requires the cooperation of many parties, from the proposal of the plan, to the modification and confirmation of the plan, to the implementation, finding ways to solve difficulties when encountering them, and finally completing them. Every step of this is not easy.

Ao Xin did not let them make a plan on the spot, but asked them to go back and make their own plans before handing the plan over to him.

The meeting was disbanded, and everyone went back to make estimates and draft plans according to his requirements.

After drafting, they met again to discuss and try to make all the data in the plan consistent with reality.

After discussion, they modified it, and then discussed it again.

It was not until a week later that a relatively perfect plan was obtained.

Then, the infrastructure team and the combat team, led by their respective captains, left the city one after another.

There were still zombies outside constantly attacking the city defense. Now all the survivors in the entire Biancheng have been concentrated in the Yanhuang base on the bank of the Bian River.

Even many survivors in the western part of the surrounding provincial capital have moved here, making the newly established base seem a bit crowded.

The huge popularity attracted zombies to attack, and there was no shortage of battles at any time.

Ao Xin walked out of the base and released thunder to clean up the zombies.

On weekdays, he didn't care about these ordinary zombies, but left them to others to hone their fighting.

But now it's different. The infrastructure team has to go out to expand the base, and these zombies are a bit of a hindrance.

He would not have to worry too much after the construction team started working and the combat teams responsible for protecting them were in place.

In a year, the combat teams had become proficient in the formation drills. With the help of the formation, they were more calm in facing the zombies.
