A month later, there will be hundreds of mutated birds and beasts, numbering at least a thousand in size, migrating here from the northern interior because of the cold.

These mutated birds and beasts are extremely cruel, and their personalities are no longer the gentle ones they once were. After evolution, their size has soared to one or two meters or even larger, so only meat can support them!

Human beings are the most abundant food in the cold winter and the easiest food to find.

They will attack any small or medium-sized human gathering place they encounter along the way, and plunder some of the humans to use as food reserves.

Before the end of the world, St City was the only way for a certain group of migratory birds to migrate, and the size of that group of migratory birds was not small.

Shu You could already imagine thousands of huge mutant birds that could withstand most ordinary firearms, hanging over the base like dark clouds.

That will definitely be the most troublesome enemy the base has faced since its establishment.

Every mutant bird basically has the speed of S1 and the power of T1, and quite a few will be more powerful. The most important thing is - they can also fly.

To say that they are not anxious, they will not fight for food with powerful enemies. As long as they can cause enough damage to them, the mutant birds will naturally leave.

The base anti-aircraft gun was developed to deal with flocks of mutant birds. Its main function is to improve the Foundation's mid-range air defense force.

And not only against the air, this thing is even more exciting when placed flat against the ground...

Shu You looked through the memories in his mind and murmured to himself: "Ten base anti-aircraft guns are enough to kill thousands of mutant birds to act as a deterrent. There is a high probability that the mutant birds will avoid this place in the future.

But there should be three to four hundred thousand flying zombies among the millions of zombies in St City in the spring. That would be troublesome.

The rate of fire of the pedestal anti-aircraft gun is too slow, and it is ultimately not suitable for group battles."

“How about Phalanx?

The Phalanx formation of the Blue Star humans is not very developed, and there is still a lot of room for improvement in technology. If it can be perfected, it will definitely be useful against extremely large numbers of enemies."

A researcher who was immersed in writing and drawing suddenly raised his head and said when he heard Shu You talking to himself.

Shu You's eyes lit up: "Yes, Phalanx!"

There is no way, the average technical level of Blue Star is higher than that of Azure Star, and the conventional interception weapons are various interceptor missiles, which are not as good as Azure Star for the development of Phalanx.

This made Shu You subconsciously ignore the Phalanx, but there was a reason for the Phalanx to exist.

The terrifying firepower and rate of fire, as well as the extremely flexible base rotation, make it easily the real king of machine guns!

This is a super cannon designed to intercept small missiles and rockets!

It's not easy to tear apart a mere first-level flying zombie.

"The project to improve the performance of the Phalanx is entrusted to you. You can select ten researchers to assist in the research!"

Without hesitation, Shu You gave the order directly.

"I won't let the boss down!"

…

Mining base...

An eight-meter-high alloy wall surrounds the entire mining area. The thirty-centimetre-thick alloy wall has several special alloy layers.

Its defense is no weaker than the several-meter-thick concrete wall of Base No. 1. The thick alloy pillars enable the wall to withstand the impact of T3!

At the top of the inner wall, there is a circle of metal pedals three meters wide, which allows soldiers to stand on the top of the wall and attack below.

Of course, the mining base is currently the most important place in Shu You's eyes, so the defensive force cannot be limited to these.

Outside the wall, twenty fortresses covering an area of ​​2,000 square meters stood majestically, with three-barreled machine guns emitting a cold light from the firing ports.

You can even vaguely see the barrel of the rapid-fire cannon, looming in the fortress' shelling mouth.

In addition, there are four task forces stationed in the twenty forts, with more than 400 fully armed soldiers!

Behind the wall, bunkers, mechanical turrets, and anti-aircraft turrets are scattered throughout the mining base.

Not even a mutated sparrow can fly in.

Including the fortress garrison, the total number of garrison troops in the mining area base is two task battalions, with an additional thirty tanks, fifty Liebee drones, and hundreds of sentries!

These garrisons are specially designated for mining bases and are not included in the foundation's military development plan!

Exaggeration?

Exaggeration is right!

In the reinforced fortress in the middle of the base, engineers were making final reports to Star Zero.

"The construction of residential areas and super-large warehouses has been completed. The residential area has a total habitable population of 10,000 people, and more than 5,000 people have been allocated.

The super-large warehouse is divided into three floors above ground and five floors below, and can store two million tons of crystal ore.

The asphalt road connecting the building and warehouse has also been connected to the road outside the base to ensure smooth traffic.

So far, the construction work of the entire mining base has been completed, and we will leave one hundred engineers behind just in case."

After the engineer finished speaking, he withdrew. Base No. 1 was still expanding and strengthening its defense facilities, and they needed to get back as soon as possible.

Xing Ling looked at the well-organized and densely defended mining base under surveillance and suddenly felt a little confused.

What do you need me to do here?

"Basic Commander, someone from Earthsea Base will be sent over in twenty minutes. Do we need a security escort?"

The smart adjutant on the wrist suddenly said.

Xing Ling retracted his thoughts and said calmly: "We have cleaned up all the mutant beasts nearby, and the zombies have gone to St. to spend the winter. There is no need to escort them."

"OK!"

…

On the vast snow-covered land, a bright and neat asphalt road leads straight to the horizon, and three thick military off-road vehicles are advancing at high speed.

Major General Ma in Zhongjian's vehicle looked incredulous: "A while ago, this asphalt road was full of scrap cars and cracks. How long has it been since it was completely renovated?

The strength of this Skynet base is so terrifying that it can actually repair a highway hundreds of kilometers long in the last days!"

“The snow seems to be cleared regularly.”

The adjutant looked at the thin layer of snow on the dark road and said suddenly.

"Tsk, rich and powerful!"

Just as Major General Ma and the adjutant were sighing, the car had quickly approached the mining base.

Major General Ma glanced up casually, and then his expression froze instantly. A giant fortress that seemed to be divided into three levels came into view.

There are four self-rotating anti-aircraft cannons on the top of the fortress, a three-barreled cannon among the twelve large shooting ports on the third floor, and four vaguely visible streamlined muzzles...

All this caused the three cars to slow down unconsciously, and Major General Ma and the officers looked in disbelief.

They used to think that the two machine gun bunkers at the entrance of their base were strong enough.

But looking at the large fortress like a war fortress in front of them, they realized that it was even powerful!

"With this kind of fortress, we can resist thousands of zombies without relying on anything else!"

The adjutant came back to his senses and said with certainty.

Turning his head, he found that Major General Ma still looked shocked and dumbfounded. The adjutant was immediately confused.

Although this is shocking, as a major general, you shouldn't be so ignorant, right?

The adjutant followed Major Ma's gaze forward in confusion, and then his pupils shrank instantly, and his lips were tangled in confusion, not knowing what to say.

The same war fortress as before!

A total of six or seven seats!

There is one every 1,500 meters!

Spreading all the way to the far corner of the alloy fence!

etc?

Alloy fence?

Everyone's eyes were immediately attracted to the shimmering silver metal wall. The eight-meter-high alloy wall looked extremely majestic, stretching for several kilometers to the left and right!

On both sides of the road in close proximity to the wall, there are various areas with thick barbed wire fences and landmine warning signs.

All this makes everyone feel strange to this place.

When the military vehicle approached, Major General Ma and several officers twitched their mouths. As highly experienced officers, they could tell at a glance.

The material used in this continuous tall alloy wall is by no means ordinary steel, but a high-grade alloy, the kind that can make military weapons!

As the car approached, four drones that seemed to have considerable combat capabilities quickly surrounded the convoy, and cold mechanical sounds came from the drones.

[Attention, please inform the identity of the unknown vehicle! Otherwise, necessary measures will be taken!]

Major General Ma was stunned for a moment, then lowered the window.

Before explaining the situation, the drone flew away directly.

【Facial confirmation

Partner No. 1—Director of Earthsea Base]

Major General Ma immediately breathed a sigh of relief.

The military vehicle slowly drove into the mining base, and the scene that came into view made Major General Ma and others' little hearts tremble, which had already suffered many heavy blows.

In the huge base, there are various bunker towers that look full of firepower everywhere, and you can even see dozens of huge heavy cannons on high platforms!

Groups of soldiers were patrolling along the clean asphalt road. At a glance, the number seemed to be no less than the number of troops at the Earthsea base!

There are also beautiful residential areas and several huge buildings with unknown functions, all of which make Major General Ma unable to move forward.

Was this military fortress, which would have taken at least a year to complete before the end of the world, really built in a month?
Chapter completed!
