The continuous sound of breaking through the air outside the building and the sound of aliens landing on the building made Nangong Qian understand the seriousness of the situation. She did not dare to make trouble again and pressed her body against Liu Yuxin. The outside of the building is now full of aliens, and any abnormal movements of them may make their whereabouts noticed.

Liu Yuxin was quite unaccustomed to the soft jade that others could not afford, but she did not dare to do anything else for a while. She could only continue to maintain such an ambiguous posture. Seeing Nangong in her arms, Liu Yuxin couldn't help but complain in her heart, hoping that these alien species would leave early.

A group of alien species flew in the distance, and several groups carried huge beasts in one after another, walked through the front desk and entered the back hall, and flew into a bottomless underground nest. The sentry, which had been hovering over the building, landed on the ground and found a corner to stand there, and began to join the carnival of alien species.

The sky gradually darkened, and the alien population gradually became quiet, and most of the alien species drooped their heads. Liu Yuxin carefully pulled her hand back, which also woke up Nangong Qian, who had been suffering for a long time, maintained the same posture for a long time, and had no initial beauty and beauty, and all that was left was numbness and stiffness.

Facing Nangong Qian's suspicious eyes, Liu Yuxin said softly:

“They fell asleep.”

Nangong Qian let out a sigh of relief and relaxed her body

“What should I do now?”

She was not able to sense the situation outside the building like Liu Yuxin, and she knew nothing about what the situation outside was.

"Two plans. One, wait until tomorrow to escape while they are out. Two, escape while they are asleep tonight."

“So which one should I choose?”

"The two plans have their own advantages, but I prefer the second one. The first one seems to be safer, but we have no idea about the living habits of those alien species. It is not certain whether they will leave the nest tomorrow. Today they have such a large harvest and will not go out to hunt for several consecutive days."

"Well, I'll escape from this city tonight!"

Nangong Qian closed the office terminal, restored the table and chairs to their original state, and then unfolded her spiritual equipment.

"let's go."

In this case, the elevator will definitely not be used, so the two of them chose to go down from the safe passage. When they arrived at the lobby on the first floor, Nangong Qian finally saw the full picture of the alien species clearly.

In the hall, dozens of strange creatures with 2-meter-high human heads and owls stood scattered in the hall, with their heads hanging on their wings, and some even snore softly.

Seeing that there was nothing unusual in the hall, Nangong Qian waved to Liu Yuxin on the stairs. Liu Yuxin, who was responsible for remote support, took the pulse rifle and gently went down to the hall to carefully avoid the sleeping alien species, handed the pulse rifle back to Nangong Qian and entered King Kong's cockpit and stood by.

Nangong Qian stretched out her right palm and began to count down:

five

Four

three

two

one!

Liu Yuxin activated the mecha in the last countdown, and rushed out of the hall before the noise of friction completely woke up the alien species. Behind them, the brightly lit research institute building suddenly became lively inside and outside, and the chaos and a quarrel was clamoring. There were even a few angry birds chasing them out and spitting out a long list of fireballs.

Liu Yuxin stopped Nangong Qian from shooting them down, and blocked all long-range attacks with the solid back of King Kong when the fireball flew. As Liu Yuxin observed so far, these alien species had very strong spirits. If they killed their companions, they might cause unpredictable consequences.

Things did not exceed Liu Yuxin's expectations. After a while of fluttering, the alien species of birds, who were not used to acting at night, circled in the sky for a while and then retracted. The one with a high identity entered the hall, while the one with a low identity fell outside the building to act as a periphery sentry.

"We've escaped? It's easier than I thought!"

Nangong Qian said excitedly, throwing away the bird's alien species' pursuit, the speed of life and death just now was indeed very exciting.

Liu Yuxin turned on all the lighting on King Kong's body

"We just got rid of those bird-body alien species that could fly"

After hearing Liu Yuxin's inexplicable sentence, Nangong Qian asked in confusion

"What?"

Liu Yuxin did not answer Nangong Qian immediately, but held Gatlin behind her in her hand.

According to the performance of the bird-body alien species in the dark just now, Liu Yuxin was sure that the abandoned gathering point was accompanied by other alien species that could complement the bird-body alien species. It was precisely because of their protection that those bird-body alien species were not exterminated in the night raid of other alien species. I believe that he had disturbed these night guardians for a long time, and they might encounter each other immediately! Liu Yuxin now only hopes that those species that have never appeared before will not have the characteristic of high-speed movement, so that at least they can escape if they can't beat them.

"Flipping..."

From time to time, he heard the sound of heavy objects falling to the ground under the black shadows around him. Now even if Nangong Qian was stupid, he knew that there were more than one mutant creatures in this ruin, which accelerated his running speed.

"Bang"

A black shadow jumped into the middle of the road where they ran away and lay on the ground with his limbs. Nangong Qian did not hesitate to shoot three consecutive shots with the pulse rifle in his hand.

"Doduo"

The 3 rounds of 2mm shellless bullets that took off the hot barrel hit the black shadow accurately and knocked it back 3 steps in a row.

"Hiss~"

The angered black shadow rushed up, but Liu Yuxin used Gatlin, who had been preheated, torn into a torn burlap bag full of holes.

Under the searchlight of King Kong, Nangong Qian saw clearly what kind of creature was blocking the road: it was a human like a skinned frog, with a layer of pink muscles on the elongated surface. No wonder they would not come out during the day. This body structured the sun's ultraviolet ray can give them fatal damage!

"This is a ghoul. The body's toughness and regeneration ability are very good. Inaccurately hitting their heart or brain, it cannot cause serious damage to them. The weakness is ultraviolet rays. High-intensity ultraviolet rays can quickly kill cells in their bodies. It is fatal to them for a long time to put them in the sun, so they are generally unable to see them appear during the day."

For these creatures that have never been seen before, Nangong Qian can tell their names and weaknesses in one word, which seems to be due to the information found on the terminal.

“Bangbangbangbang…”

Several more ghouls jumped onto the highway.

"Follow me!"

Liu Yuxin shook Gatlin in her hand, and the bright red laser light was scattered into a small fan, knocking over several ghouls that blocked the way and protruding out of the ghouls' encirclement.

But this long road seemed to lead to hell, and there were constant visitors from the abyss with sharp claws and terrifying claws coming out of various places to prevent them from leaving the city.

In the battle with ghouls, in order to avoid being surrounded by many ghouls, Liu Yuxin and the others had already deviated from the originally scheduled evacuation route and left the main road and kept hiding between the streets.

Surrounded by ghouls, Liu Yuxin and the others have been playing hide-and-seek in the city for hours with those alien species. Although they were not hurt, they were still far away from leaving this city.

"How come there are so many!"

Liu Yuxin is now hiding in a house, gasping heavily, while King Kong is thrown in a corner by him. Even Liu Yuxin, driving the heavy mecha for several hours in a row is a heavy burden.

"It's all my third uncle who caused the trouble"

Nangong Qian was also very guilty about the fact that the matter had developed to this point. After all, the accident was caused by her family's relatives. After hesitating for a while, she finally decided to reveal some inside story to Liu Yuxin.

"My mother successfully decomposed a magical serum from biological samples transferred from the 521 research base. It is usually in a normal inertia and does not react with anything, but has a special liking for the evolutionary factors that spread across the planet after falling stars."

"It can dissolve and swallow up the evolutionary factors that we have been helpless in technology recently, and then it also begins to collapse, just like the white blood cells in our body facing foreign invading bacteria. My mother was going to take a large number of walks into the Earth's atmosphere in outer space. This antibody makes all the alien species on the planet weak, so that humans can rely on the technological reserves of the past to regain everything they have."

"But this plan was opposed by other advanced evolutionists. They opened a different approach and studied how to actively activate serum, allowing it to actively capture a large number of evolutionary factors for the human body, and convert them into its own storage. With the help of others, this study made a breakthrough. The serum was activated, and the effect was the same as they expected. For a period of time, even my mother almost thought she was overthinking, thinking that humans had mastered the path of independent evolution and walked ahead of the genius girl at the 521 base."

"But in fact everyone was wrong! One day the serum that was preparing for the experiment was out of control! The violent serum showed its terrifying side, which prompted several experimental subjects to evolve at an unimaginable speed, breaking through to the advanced level at an extremely fast speed, killing the entire research team involved in the experiment and eliminating the security personnel who came to rescue."

Then there wouldn’t be so many alien species? How many alien species are there in the sky and the earth, plus these endless ghouls, are there in total? Hundreds, thousands, or tens of thousands!

Nangong Qian smiled bitterly about Liu Yuxin's questions

"After just obtaining research results, in order to quickly obtain a large number of evolvers to expand their strength, San Uncle has injected serum into most residents, waiting for their independent evolution to obtain a large number of evolvers. However, after the accident broke out, those residents have become a timed hidden danger of unknown when the explosion will occur."

"So your family chose to give up this gathering place?"

Liu Yuxin took up Nangong Qian's topic. The reason why he did this was because he had inferred the approximate incident. Judging from the Nangong family's actions of erasing the gathering points, it was probably that the cleaning plan was prepared at that time, but now it seems that things have changed unexpectedly and they have not achieved their goals, and they have even lost a lot of manpower. Otherwise, Nangong Qian's mother would not have lost it here. Liu Yuxin interrupted Nangong Qian at this time to avoid the most embarrassing situation.

"My physical strength has been consumed, and it seems that we can only wait here until dawn."

"no!"

Nangong Qian shook her head firmly
