The world is frozen: I spent a billion dollars to build the strongest safe house

The flame appeared out of thin air again, and the zombies who were attacking the steel door were immediately surrounded by flames and screamed loudly.

But the giant zombie was not greatly affected. With its body covered in flames, it still punched the door one after another.

"Haha, I finally found you!"

The red-eyed zombie let out a strange laugh, waved his hand, and hundreds of corpse bugs flew towards one direction of the hillside.

A ball of flame burned the approaching corpse insects cleanly, but also exposed the location of a young woman.

She waved her hands and released several fireballs, but suddenly came out of her hiding place, turned around and ran towards the top of the mountain.

"Li Na, don't run away! Who will protect us if you run away?"

"That's right, Li Na, come back!"

"Three of our superpowers have died in the battle, and now we can only rely on you!"

"No wonder you have to defend outside. It turns out you want to escape easily!"

"Li Na, you coward and traitor!"

"..."

Panic voices came from the shelter, accusing the human woman who escaped.

Su Mu, who had sent several insect drones to observe closely, heard the collected sounds and shook his head.

The human heart is always the most vicious!

This young fire-type superpower seems to have good strength. He should have reached the second level. If he wanted to escape, he would have escaped long ago before the zombie army surrounded him. Why bother to resist here?

Facing two second-level zombies and thousands of ordinary zombies, a temporary strategic retreat is necessary!

Sure enough, the young woman ignored her and continued to climb towards the top of the mountain. However, after just two steps, she was suddenly caught in mid-air by a strange bird that fell from the sky.

The bird seemed to be a zombie after death of some kind of raptor. The body was thin and strong, and the skin showed a rotten gray-green color. Most of its feathers fell off, revealing a large rotten hole in the chest and the ribs inside.

With just one peck, the strange bird blinded one of Li Na's eyes, and then, as she screamed, it used its claws to tear it into two pieces.

After being so seriously injured, Li Na still did not die for a moment. She mustered up her last strength, and her body burst into a strong red light, surrounding the strange bird zombies!

wipe! There is actually a second-level bird zombie hiding in secret?

Su Mu took a breath of cold air. Are zombies' IQs that high now?

Have you all started learning the Thirty-Six Strategies and playing Sun Tzu's Art of War?

Li Na's blow before her death obviously also severely injured the strange bird zombie. It fluttered crookedly in the air, and finally managed to stabilize its body.

Seeing that the giant zombie had smashed the thick steel door out of shape, revealing a large hole, several zombies scrambled to crawl in, and there was a burst of crying inside.

Su Mu glanced around and didn't see the hidden figures of other second-level zombies. He sneered and took out his Gauss sniper rifle and pointed it at the red-eyed zombie standing behind and being protected by hundreds of subordinates.

He had already put on the crystal core that exploded from the brain of the ice superpower Feng Tianjiao. The blue light from the muzzle flashed, and the red-eyed zombie and hundreds of its younger brothers were frozen in a large piece of ice at the same time!

"It is worthy of being the crystal core of a second-level ice power user. Ice power is powerful!"

Su Mu sighed in admiration and pointed the gun at the strange bird zombie in the air.

Under the super high speed of the Gauss sniper rifle bullets, the strange bird zombie did not react at all. It was frozen into a large piece of ice and fell to the ground. It rolled a few times and landed right in front of the red-eyed zombie.

In the ice, the frightened expressions on the faces of the strange bird zombies and red-eyed zombies are lifelike!

Now the giant zombie who was smashing the door also noticed that something was wrong and turned his head to look down the mountain.

I saw countless 30mm artillery shells with flames falling on the hills, exploding into clouds of flames, and many zombie pits were blown apart without saying a word!

There were stumps of limbs and broken arms everywhere on the mountain, and blood was flying everywhere. The giant zombie was about to make a move, but was frozen into an ice lump by a blast of cold air, and the steel door behind it was sealed with ice!

By the time the two close-in defense cannons on the roof of the base vehicle stopped rotating, there were only a few zombies left on the hill.

The car door opened, and Zhang Shuai rushed out with five six-legged robots and a dozen combat robots, firing at the remaining zombies and collecting crystal cores.

The three frozen second-level zombies were all smashed to pieces by the 30mm close-range anti-cannon. Unfortunately, only one second-level crystal core was found in the heads of the strange bird zombie and the giant zombie.

The head of the red-eyed zombie was smashed to pieces by Zhang Shuai, but there was still nothing!

Didn't it completely kill it?

Su Mu was a little confused, but now was not the time to think too much about this. After Zhang Shuai and the others finished cleaning up the battlefield, the base vehicle roared away again!

As for rescuing those who were frozen behind the steel door, Su Mu expressed no interest at all and let them fend for themselves.

These people even slander the fire power users who are desperately trying to protect themselves. They are not worth rescuing!

But this second-order fire crystal core is really beautiful. Su Mu sat in the cab, holding up the crystal core exploded from Li Na to admire it.

Although a lot of shells were wasted, Su Mu was still very happy to get 3 second-order crystal nuclei and hundreds of first-order crystal nuclei at once.

In a sealed basement in the distance, a corpse lying in a coffin suddenly opened its scarlet eyes, revealing an angry look.

"Damn it, it's you who ruined my life again!"

"Su Mu, you and I are at odds with each other!"

Two days later, Su Mu finally drove to the Jinshan Refinery in the south of Shanghai.

Jinshan Refinery is the largest refinery near Shanghai, with an annual crude oil processing capacity of 1730 million tons and the ability to produce more than 120 petrochemical products and fuels.

Even if there is only one-tenth of the inventory in the warehouse, it is still a huge number.

What's more, there are a large number of factories, machinery, and equipment inside. Putting them into infinite space will also be a huge help to the gap in your own alloy!

Jinshan Refinery occupies a very large area and is surrounded by residential areas, supermarkets, office buildings, parks and other supporting facilities.

It stands to reason that for this kind of resource-based production enterprise, the government should take it back immediately and start production, but there is silence inside.

Su Mu used monitoring satellites to scan several times, but no human survivors were found.

On the contrary, there are many human and canine zombies wandering inside, and there are also many black birds sitting on the roof of the factory, which are probably transformed from the humans and animals that died in the snowstorm.

Su Mu thought for a while and guessed that fireworks were strictly prohibited here, and there were zombies turned into workers on duty, which had even evolved, and the army did not dare to bomb.

Since the military is unwilling to destroy this refinery, it can only rely on specific superpowers to use cold weapons to explore and eliminate zombies. The efficiency is too low, so it can only be retained for the time being.

Su Mu hid the base vehicle, asked Zhang Shuai and Li Jingxuan to follow him, and slowly walked into the gate of Jinshan Oil Refinery.
