When all the supplies are delivered, it is dark, the military factory is still lit up, and since the production line has been erected, it will maintain 24-hour uninterrupted work efficiency to complete the drone orders from Shangjing.

Late at night, the leaders had already fallen asleep, and Huang Shang felt that Su Lan's breathing was deep, so he broke free from her embrace, put on his coat, and walked to the base schoolyard.

At this point in time, except for the xenos lurking around and fighting each other for their prey, there was no one to be seen.

Huang Shang raised his head and looked up at the sky, the dense stars were in full view, and the most beautiful scenery in the universe was presented stunningly without the illumination of the surface of the earth.

According to my father's account, some elites on Earth have long boarded the spaceship for escape and embarked on an uncertain journey of the future of mankind in the vast sea of stars.

But there is only one earth, it was and it is now.

Although the current earth is dilapidated, like an alien abandoned by the gods, this also just gives Huang Shang a chance to stretch his strengths, if in normal times, he is just an ordinary fresh graduate, let alone change the earth, he doesn't even have the ability to change himself.

Sometimes, people will be extremely powerless in the context of the whole society, although there is still a breath in the heart, but the reality will always make most people surrender, and eventually become mediocre.

At some critical junctures, when a person is unable to change his situation by relying on his own strength, he will believe that there is such a thing as fate in this world, some people will be prosperous and rich when they are born, and some people, even if they have worked hard all their lives, cannot afford to buy a toilet in a house with only 70 years of residence.

But fate seems to have played a big joke with Huang Shang, not only giving him the ability to survive in the end times, but also giving him the ability to warp the entire earth, of course, these are all later words.

He turned on his phone and woke up the sleeping system.

In order to cope with the threat of a strike from the Seventh Fleet at any time, he had to invest all the steel he had brought during the day into the reinforcement of the city walls, and he also had to protect the sky above his head.

You must know that the entire aircraft carrier formation, its land strength is simply weak and pitiful, before the end of the world, the aircraft carrier formation can send marines, but now, even if he sends tens of thousands of marines, it is not enough for Huang Shang to hit a shuttle with a sentry machine gun.

However, this does not mean that the Seventh Fleet does not have any combat effectiveness at all, and the combat strength of the entire aircraft carrier is basically concentrated on air combat capabilities.

The Seventh Fleet has approximately 50 to 60 warships, 350 warplanes, and a full fleet strength of 60,000 men, including 38,000 officers and men and 22,000 officers.

If 350 fighters are evenly distributed among one country, it may not be fearful, but if they are concentrated at one point at the base, the situation is much more dangerous.

After all, the base is so big, if the Seventh Fleet wants to retaliate, it is really simple, not to mention that some specific types of fighters are even equipped with nuclear warheads.

That's just a hell of a thing.

The last time he was baptized by a nuclear bomb, Huang Shang was spared by moving the surface materials of the entire base underground, but now all kinds of equipment and buildings on the surface are being built in an orderly manner, and he will not move the base underground because of the military operation of a fleet.

At this time, Huang Shang had two main strategies to deal with the Seventh Fleet, the first strategy was to force the battle line to the vicinity of the Seventh Fleet, but if he did so, the military strength of the entire base would be seriously weakened, and his enemy was not only one.

The second strategy is to further strengthen the defense, since the main combat strength of the Seventh Fleet is concentrated in the air, then it is far from enough to rely on the city wall alone, and the establishment of a complete air defense early warning system can fundamentally avoid the base from being attacked.

This depends on the assistance of the system, clicking on the Doomsday Main City app, Huang Shang quickly found the prevention and control column, a series of defense systems dazzled him, but the remaining hunting points only allowed him to unlock the first two.

"Ant queen prevention and control missile launch vehicle: the effective range is 60 kilometers, it is a short-range air defense missile, it can launch three air defense missiles at a time, once locked, the target will not be able to escape."

It's very ordinary, Huang Shang browsed the introduction above, but the range of 60 kilometers is enough to defend the base and surrounding territory, and each queen ant prevention and control missile launcher only needs 50 hunting points to unlock.

"Let's try the water in five cars first."

After clicking on the construction, the queen ant prevention and control missile module entered the countdown, and the prevention and control system of the next module really attracted Huang Shang's attention.

"Space-based protective layer: The entire city is included in the scope of the protective layer, which can effectively prevent a series of strikes such as the enemy's air force, nuclear bombs, and space-based weapons.

Looking at the unheard of term, Huang Shang had a headache, but judging from the degree of scientific and technological development in the next few decades, it is estimated that space-based weapons and concentrated energy strikes should be the most cutting-edge weapon combat modules in the future.

On top of that, the introduction mentions immunity to nuclear bombs.

If a space-based protective layer is added to the base, the prevention and control level of the entire city will be raised to the extreme, although I don't know what its specific defense effect is, but it will definitely be completely fine if it is like F35.

"There are a total of 1,005 hunting points, and the cost performance is quite high."

Without hesitation, he clicked to be sure, but what made Huang Shang puzzled was that the system did not give any response, and the next moment, he seemed to feel a bright light coming from all around, and a shocked look flashed in his pupils.

I don't know when, a ball of light glowing white appeared directly above the base, and what is even more incredible is that the ball of light seems to be gradually dissolving, and the ablated part turns into a white film of light, with the ball of light as the center and spreads out in all directions.

Huang Shang froze in place, and after a long while, he understood what kind of existence this space-based protective layer was.

After the light sphere completely dissolved, the entire base was shrouded in a film of white light, which was semi-circular, like a protective umbrella, wrapping the sky above the base in all directions.

After about half an hour, the light of the space-based protective layer gradually faded, and when you look at it with the naked eye again, you can't find anything at all, and all that remains in the sky is the vast sea of stars.

Suddenly, Huang Shang's body stiffened, and something seemed to be on his back.

"It's so cold outside, why do you want to come out and get some air?" Su Lan's gentle voice came from behind, and her slightly sleepy tone made Huang Shang feel a little reassured, hoping that she hadn't noticed all this, otherwise she wouldn't know how to explain it.

"It's okay, I feel stuffy after living underground for a long time, just come out to breathe, if you're sleepy, go back-"

"Is that your overrun power, or something else?" Su Lan's seemingly casual question made the latter speechless.

After a long silence, he still didn't know how to speak.

"It's okay if you don't want to say it, I can understand that." Feeling being held by a pair of hands from behind, and a strand of fragrant hair also swept over the base of his ear, Huang Shang suddenly wanted to explain something.

"Let's go, go back to sleep, I always have nightmares without you to hold me." Su Lan smiled and blew into his ear.

"Okay, go back to sleep." Huang Shang suddenly turned around, hugged her across his chest, and walked back to the basement.

"You'll know everything later."

"Okay, then I'll wait for you to tell me in person."
