Interstellar arena

There is a glass curtain wall in the hall outside the vault. After the alien disaster broke out, the glass curtain wall was protected by a thick layer of metal gates and windows, which is why there is no sunlight in the hall.

The steel shutters were slowly closed with a slight sliding sound, and the dazzling sunlight shone in.

After getting used to the light, people looked out of the window, and all of them gasped.Outside the window is a huge black vortex formed by circling alien shapes, the scene is magnificent and incomparably spectacular.

The vortex rotates counterclockwise at an altitude of several hundred meters. Above the vortex, from time to time, black aliens like bats join the huge vortex, like moths to a flame.These aliens that were thrown into the vortex immediately glide and fly with the vortex, and as the aliens keep joining, the vortex becomes thicker and thicker, like a black dragon connected end to end.

It is no exaggeration to describe this wave of aliens as a giant dragon. In fact, at this time, because a large number of aliens were circling in the same direction, a huge airflow was set off in the air, and the airflow actually produced a vortex-like suction. The dust and debris on the ground The piece of paper was sucked into the sky along with the vortex, and it also flew along with the vortex, making the vortex appear more imposing——

Terrible Alien Tide!

Looking at the darker and darker sky, Zhou Qing's delicate body was trembling, and fearful eyes shot out from his eyes.In fact, it wasn't just Zhou Qing who had a look of fear, but also the five big men and A Jing's group of teenagers who all looked dull.

Anyone who hangs out on the drow star knows the horror of the Alien Tide.

In fact, there are many kinds of alien tides. The aliens running wildly on the ground also belong to the alien tides, and the aliens flying at low altitudes also belong to the alien tides. When they appear from space cracks, they can also form large-scale alien tides.

Among the various alien tides, the most powerful one is the alien tide formed in an instant after space migration and exiting the space crack, because at this time, the alien tide has formed a height of several hundred meters, and this height is in the form of horny If you dive, it can form a terrifying impact, and even a single alien can crash a mecha weighing dozens of tons.

In previous battles, the biggest casualty caused by aliens to humans was the moment they came out of the space crack, and the fearless collision without any warning made human's high-tech methods unable to function at all.

Usually, the first batch of aliens to come out of the cracks in the space are dead soldiers, and they completely commit suicide by committing suicide together. Therefore, this kind of attack is also the most terrifying, most terrifying and deadly catastrophe.Often, after a round of charging, a city's power transportation and communication systems are destroyed in sevens and eights, some ground defense systems are basically paralyzed, and many established ground troops are directly wiped out——

Undoubtedly, the high-altitude suicide dive is the most primitive battle. However, because of its location uncertainty, suddenness and no warning, human beings have not yet found a specific way to deal with the alien high-altitude dive.

"It's over, it's over, a large number of aliens have migrated from outer space to Xicheng District, and we are surrounded." Zhou Qing tried to slow down her speech, trying to calm her emotions. As an excellent soldier, she knew very well , panic will only make her die faster.

"Yes, we are trapped." The five big men were obviously not as good as Zhou Qing's psychological quality. They stared blankly at the huge black vortex outside the window with a pale face. Joy swept away.

Among these people, only Liu Fei and Ah Jing remained indifferent, and even the group of teenagers and mercenaries showed palpitations.

In fact, anyone who knows a little bit about aliens knows the horror of the tide of aliens coming out of space cracks.

The aliens coming out of the cracks in space are more ferocious and fearless than ordinary aliens.According to the research of scientists, this is because the aliens lost a lot of heat energy during the long-distance migration. During this period, the aliens were very hungry and would frantically attack any moving target.

"Look at you." Ah Jing's eyes fell on Liu Fei's face.

"No, it's up to you."

"Who was the one who said brazenly that he wanted to protect us from going out?" A Jing's face showed a mocking sneer.

"If our agreement is negotiated, I will naturally protect you from going out." Liu Fei's ridicule at A Jing was not unique, with a calm expression on his face.

"I'm [-]% like them. If you can get me to Dongcheng District safely, I only need one billion federal coins. However, the ugly words can be said up front. If you can't provide protection or let me participate in the battle, Then, the agreement between us will not have any binding force." Zhou Qing hurriedly said.

"Of course." Liu Fei glanced at the growing vortex outside the window.

"Okay, it's a deal."

"I don't believe you." Ah Jing snorted coldly.

"Ajing, even if you hide in the basement, it is impossible to survive this alien crisis." Liu Fei looked at Ajing with a blank expression.

"Ah - you - how do you know?!" Ah Jing's face changed color, he didn't expect Liu Fei to guess his intention.

"From the current point of view, for some unknown reason, this building is the base camp of aliens. When you rushed into the building, you killed a large number of aliens. There is no doubt that your actions have alarmed the high-level people in this building. Aliens, they organized a series of siege, but this siege was broken because of my appearance—”

"Your appearance! Hahaha——" Ah Jing swiped the long knife in his hand, and laughed loudly. The laughter was filled with endless contempt. "You mean, without your presence, we would have been surrounded by aliens?"

"Yes."

"I want to hear how you saved me."

"When you climbed up from the first floor, didn't the number of aliens increase as you went up?"

"——" Ah Jing opened his mouth, looked at each other with a group of teenagers and did not speak. Obviously, Liu Fei was right.

"As the floors get higher and higher, there are more and more high-level aliens. At the same time, you have suffered casualties, have you?"

"——Yes!" A Jing hesitated for a moment, but still nodded, he is not a person who is good at lying, besides, the facts are in front of him.

"Just when you couldn't bear it anymore, the number of aliens suddenly decreased. When it was close to the 150th floor, the aliens disappeared completely. Do you know the reason? Because I know you are below, so I sent someone to guard the stairs Killing the aliens with your mouth, you must have seen the piles of alien corpses."

"It's just a coincidence." Looking at Liu Fei, who was not a few years older than him, Ajing felt an inexplicable chill on his back. This person is too scary, and his every move is actually calculated by him.

"Coincidence? Hehe, we have at least dozens of ways to block the door of the fire escape." Liu Fei glanced at the alien vortex outside the glass curtain wall again.

"You want to tell me that you saved us!"

"No, I'm just telling you that it's useless for you to avoid the tide of aliens. The aliens will not abandon this building. Moreover, the aliens that formed the tide of aliens in the sky did not migrate from outer space. They all lived in drow. Star-born, native alien-"

"As far as I know, aliens don't have the ability to fly at high altitudes. If they didn't migrate from outer space, then can they fly to an altitude of hundreds of meters? We are now on the 150th floor."

Ajing glanced at the increasingly frightening black vortex outside the glass curtain wall, and slowly retreated into the vault. At the same time, a group of teenagers also retreated into the vault.

Seeing Ah Jing retreat towards the vault, the five big men and Zhou Qing also subconsciously retreat towards the vault.

The atmosphere became tense, because the edge of the black vortex was almost approaching the glass curtain wall——
