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

Now the base was very empty and had no strength to support a war. Su Mu did not dare to neglect and drove the base vehicle northwestward until he entered the country and did not stop.

Hey hey, here I come to the Eiffel Tower!

After experiencing the global freeze and zombie crisis, the entire population of Europe was reduced to ten percent, and many places were abandoned. People gathered in shelters to survive under the protection of the army.

There were still zombies and beasts running rampant outside the shelter, but few of them exceeded the third level of strength, and they did not pose any threat to Su Mu at all.

Su Mu drove the base vehicle through the streets and alleys of Faguo. The skeleton of the city was still there, but the once bustling streets and towering buildings had turned into ruins, shrouded in a kind of apocalyptic desolation. middle.

However, Su Mu had been used to this situation for a long time, and he didn't feel sad at all. He just ordered the robot to collect metal products in various cities.

The country is worthy of being one of the first developed countries in Europe, and various metal-made items can be found everywhere in the city.

Over the past few days, the base vehicle has been filled with a variety of metal products, from discarded car parts to broken steel bars, from railway bridges to factory equipment, all of which have been collected by Sumu's robots and transported back to the base. car.

In order to improve work efficiency, Su Mu even took the trouble to collect various wastes in the city into infinite space, and then put them into the garbage conversion processor to convert them into various useful materials.

Perhaps it was because Su Mu's hands were stained with the blood of many gods and monsters and he had a reputation for being evil. No country or zombie monsters came to provoke him anymore. His plan to demolish the city and collect supplies went very smoothly.

With the abundance of supplies, the factories in the base car are operating at full capacity. Various robots, shells and explosives are flowing down the production line, and the speed of demolition of the city is gradually accelerating.

Along the way, Orleans, Paris, Luxembourg, Brussels, Amsterdam, Frankfurt, Munich, Berlin and other dozens of cities were dismantled into white fields, and the amount of alloy in the hematoxylin base finally reached 1 million tons.

Seeing the green prompt in his mind that he was allowed to upgrade, Su Mu almost burst into tears.

Nana's, it was not easy. It took him more than half a year and fought in most of the Blue Star to finally collect all the materials needed for the upgrade.

"upgrade!"

Su Mu suppressed his excitement and quickly started upgrading the doomsday fortress system.

[Ding: The upgrade of Doomsday Fortress has begun. The upgrade time is 48 hours. The current progress is 0%. The base can be used normally during the upgrade. 】

The system finally started to upgrade again. Su Mu felt that the mountains of various materials in the infinite space disappeared out of thin air, and he didn't know where they went, leaving a large area empty.

"I didn't expect that the prisoners in the base would be considered as the population by default. This system is quite user-friendly!"

Su Mu nodded with satisfaction. In such troubled times, the chance of survival must be given priority to his compatriots. He originally wanted to return to Daxia to recruit people, but now he doesn't have to go to so much trouble.

He had been working hard recently and was feeling a little tired both physically and mentally. Su Mu drove the base vehicle to a hidden location in a valley, preparing to quietly spend the time during the system upgrade and take a rest.

Of course, it has nothing to do with wanting to play the King Zhou game of chasing each other with Qin Keer and Li Jingxuan.

Two days later, Su Mu finally heard the message that the system upgrade was successful.

[Ding: The Doomsday Fortress has been successfully upgraded to level 2, and related areas and functions have been unlocked. Please explore the specific situation by yourself! 】

[Requirements for next level upgrade: 1 trillion tons of alloy, 100 billion tons of grain, 1 star stones, 1 void crystals, 1 kilograms of star sand, 10 third-order crystal nuclei, and fourth-order crystal nuclei 1 pieces, 10 godheads, and the population in the base exceeds 10! 】

Su Mu was shocked when he saw the upgrade conditions. The total weight of Blue Star is only 60 trillion tons, and the light alloy is 1 trillion tons. This requires me to dig up a planet!

I’ve never seen those star stones before!

And what is the Godhead?

It has never been revealed!

Before he could finish sighing, a system prompt sounded in his mind.

[Ding: The base has been upgraded successfully, and the host will be rewarded with "three heads and six arms"! 】

"boom!"

A powerful force exploded in Su Mu's body. He felt that his whole body was about to boil. Black and red flames ignited all over his body, burning his clothes completely, and dark streaks appeared on his exposed skin. The golden lines seemed to be some kind of mysterious pattern.

That power was like an endless wave, washing over Su Mu's body over and over again. There seemed to be something under his ribs that was about to come out!

In Su Mu's mind, a giant with three heads and six arms, standing tall and tall, stood on the cracked earth and roared to the sky with blazing flames all over his body. As he moved his hands and feet, the mountains and rivers were cracked, the sun and the moon were dim, and behind him, there was a mountain of corpses and a sea of ​​blood, and the setting sun Like blood!

"what......"

With a long roar, the flesh and blood squirmed under Su Mu's ribs, and two pairs of arms actually grew. Each arm was muscular, thick and powerful, and there was a faint golden light flowing in the palms of the hands.

"This is...three heads and six arms?"

Su Mu slowly opened his eyes and looked at his new body in surprise. He tried to wave his newly grown arms and felt a powerful force pouring out of it, as if it could tear apart all obstacles!

"Great, with these three heads and six arms, my strength has improved by more than one level compared to before!"

His heart was filled with shock and joy, "Moreover, the strength of Shura's true body has almost doubled. Now I dare not say that I can resist mushroom eggs, but ordinary missiles definitely pose no threat to me!"

[Ding: Doomsday Fortress unlocks the fourth form of the base, the space carrier! 】

[Space Carrier: The fortress base can turn into a huge space carrier under your control, soaring freely in the sky, whether it is through clouds or across the ocean, it will be possible. After the fortress base transforms into an aerospace carrier, it will have stronger defense and attack power, becoming your ultimate weapon to conquer the vast starry sky! 】

Hearing the new prompt from the system, Su Mu was overjoyed and felt a rush of pride surge into his heart.

The space carrier is the ultimate weapon in science fiction movies. I never thought that I could own such a powerful battleship!

He immediately checked the system interface in his mind, and saw that there was indeed an option for "space carrier" in the originally blank area.

With a thought in Su Mu's mind, the body of the base expanded rapidly, the metal on the surface began to flow and deform, and the shell gradually unfolded, revealing the complex structure and mechanical devices inside.

With a roar, the base vehicle completely transformed into a huge space carrier, suspended in mid-air, exuding a powerful aura.

Images sent from monitoring satellites show the majesty of the entire space carrier, like a giant steel city floating in the sky.

The hull is streamlined and covered with smooth metal armor, exuding a cold light.

The huge bridge towers into the sky, and several pairs of huge wings and propellers protrude from both sides of the hull, allowing the entire hull to float stably in the air.
