The heart seemed to burst through the chest cavity and jumped out, as fast as a storm.

The elevator door slowly opened at an extremely abrasive speed, Song Qingxiao's back tensed, his hand holding the dagger across his chest, and he took several deep breaths in succession before he stiffened his head and forced himself to look at the elevator door.

She didn't know what she would see when the elevator door opened, or if there was the creature in the lab that she was worried about occupying half of the island.

At this moment, a lot of things flashed through Song Qingxiao's mind, the unknown produces imagination, imagination brings fear, that kind of feeling, it is really difficult to accurately summarize in words.

As the elevator door staggered to the side, a large amount of cold air poured in through the cracks in the elevator.

It may be that the location of the laboratory is in the heart of the island, and the cold is like a needle hidden in the cotton, with an eerie feeling, which makes the skin irritated and the hair stands on end.

There was a strange and pungent smell in these cold air, Song Qing couldn't help but wrinkle his nose, and the expression on the face of No. 7 had changed from fear and caution to a relaxed color that was difficult to hide.

She happened to be standing on the side of the elevator door opening, and she should have seen the scene outside the elevator first.

From the look on Seven's face, you can guess that there is nothing dangerous in the laboratory for the time being.

After about ten seconds, the elevator door finally opened, and the true face of Changsheng Technology slowly appeared in front of Song Qingxiao.

The dim light in the elevator shone out, pulling out a long line of light and shadow from the tiles on the floor.

Compared with the messy and dirty lobby of Changsheng Technology that Song Qingxiao had seen before, this place is undoubtedly much cleaner.

After exiting the elevator, there is a room separated by a glass door, behind which are several steps, and below the stairs is an open and anomalous laboratory.

Even though Song Qingxiao had already been mentally prepared before entering the laboratory, the moment he really saw the laboratory, he was still shocked by Zhou's investment back then.

The entire interior of the island seems to have been hollowed out, and from the echoes, the sound of the wind, and the endless depth, you can guess that this laboratory is huge.

The square within Song Qing's small line of sight is at least ten meters high, which looks magnificent and atmospheric.

Perhaps because it has been abandoned for many years, there are some problems with the wiring of the power supply, or because the power switch between the laboratory and the lobby is not shared, the headlights of the underground laboratory are not on.

The light from the elevator can be faintly seen, and the laboratory is filled with various cabinets, glassware, and research equipment.

The laboratory is divided into countless partitions by a series of glasses, and because of the dim light, it is not very real from a distance, giving people the appearance that the laboratory seems to be boundless.

It was very quiet here, so quiet that even Song Qingxiao's deliberately suppressed breathing could be heard clearly.

A few strands of hair fell down her cheeks, swaying gently as she exhaled the heat, and she twisted them up, cutting them short with a knife so as not to affect herself.

The two stood in the elevator for a while and slowly stepped out of the elevator.

At the moment of stepping on the laboratory floor tiles, even if Song Qingxiao and No. 7 instinctively relaxed their steps, they still made a small 'click' echo.

After they came out, the elevator door made a screeching sound and slowly began to close, and the light in the elevator was blocked little by little, and Song Qingxiao's eyes slowly began to darken.

No. 7 resisted the urge to press the elevator door open, opened the distance between him and Song Qingxiao without a trace, felt the flashlight in his bag, and began to look at the surrounding environment after there was light.

This is supposed to be a small lounge, with rows of protective clothing hanging next to it, a sofa for resting on one side, a refrigerator, a water dispenser and other things.

From the existence of these things, Song Qingxiao can imagine that when Changsheng Technology was still in use, the scientific researchers who entered here probably had to change their clothes before entering the laboratory.

The suits were originally white, but they had not been used for many years and had been slightly discolored from the dust.

Seven's fingers tugged at the corner of the garment, and the fabric turned to dust on her hand.

After Song Qingxiao entered the laboratory, she didn't dare to be careless, mobilized her spiritual power, and her divine sense covered this lounge, and what appeared within the scope of her spiritual power, in addition to her and No. 7, there was also an invisible 'No. 3' that followed her side at a distance of nearly three meters.

In addition, she did not sense the existence of other active creatures, which undoubtedly made Song Qingxiao breathe a sigh of relief.

After making sure that this small area was safe for the time being, she was no longer tiptoeing like before, but felt much more comfortable.

"Let's find a way out of the lab first." Song Qingxiao lowered her voice and spoke, in this empty space, it was too quiet, and when she spoke, there was a faint echo.

No. 7 was stunned for a moment, then squinted his eyes, and the sound of 'hmm' was accepted.

"How do you open the door?"

No. 7 pointed to the closed glass door in the distance and asked: "The power supply here should not be fully turned on, the glass door is not switched, and the sensor device is installed, it should be an automatic door." ”

But when she tried to walk through it, there was no movement at all, apparently out of its senses.

"Find out if there's a power gate here." Although the power supply was turned on in the lobby before, the laboratory lights below were not on, and Song Qingxiao guessed that this was probably because the power supply of the laboratory and the lobby was a set of systems.

The two of them found the switch box behind the refrigerator by the light of the flashlight held by Seven, and after opening the lid of the box, Seven turned the brakes up again.

There was a quivering sound of electricity underground, and after about three or four seconds, a series of lights lit up in the laboratory glassware and some of the experimental troughs outside the lounge.

The light was faint and glowing, making the light in the laboratory a little hazy.

These little lights shine through the glass, reflecting hundreds of shadows, because the place is huge, giving people a sense of endlessness, combined with the environment at this time, not only does it not look beautiful, but there is a kind of eerie feeling.

With the lights, the blurred shadows of the two were reflected on the glass door, and No. 7 glanced at it and forcibly held back the apprehension in his heart:

"Only this one gate was found, and it was all opened." But it's just that the lights in some cabinets are on, and the headlights that can bring strong light overhead are not on, I'm afraid that there is a problem with the wiring.

Not to mention that neither of them is good at repairing these things, even if they can repair them, the top priority is to get out of here first, and then talk about it, and there is no time to toss.

Song Qingxiao walked to the glass door, the glass door was still closed and did not open, she retreated, and walked over again, but the door was still silent.

"What should I do?"

No. 7 saw her movements, and also followed, and when she moved, No. 3, who was locked by Song Qingxiao's spiritual power, also walked around, and No. 3 obviously made up his mind to follow the two firmly.

The moment No. 3 followed, the sensor that had not moved seemed to have received the induction, and the glass door that had been closed silently slid open to both sides, revealing a gap nearly a meter wide that could allow two people to enter side by side.

The door opened outside, and in the dim light, dust poured in with the air from outside, floating and sinking in midair.

When No. 7 saw it, he was overjoyed.

Several people passed through this gap and entered the laboratory.

As soon as he passed, the door closed silently.

No. 7 was stepping down the steps, and Song Qing's heart moved, and his steps paused.

"How?" Seeing her move, No. 7 couldn't help but raise his eyebrows and asked.

"Try this."

After the door was closed, I don't know if it was a psychological reason, Song Qingxiao always felt that the laboratory was extremely gloomy, and she had to leave a way out for herself.

Seven had an impatient look on his face, "What are you doing with all this?" ”

Song Qingxiao ignored her and stood in front of the door again, the door did not move this time, obviously this sensor was corroded by time, and it was not working.

She raised the dagger in her hand and slashed at the glass, and when the tip of the blade touched the glass, there was a squeaky sound, and the sound spread, and there was a squeaky echo in all directions, and then the blade of the dagger easily sank into the glass, penetrating the glass.

The glass was drawn by her into a horizontal frame nearly a meter long, even if the voice was low, but it also made the listener extremely uncomfortable, Seven couldn't help but reach out and press his ear, his eyes flashed gloomy:

"What the hell are you going to do?" The dark environment tortured her will, making her gradually a little unbreathable, stripped of her concealed personality, revealing some true temperament:

"It's hard to say if there is any danger here, you are making a movement now, afraid that we will not die fast enough, right?"

"If you're not satisfied, you can act separately from me, I didn't pull you!"

Song Qingxiao made a movement in his hand and pushed back the words of No. 7.

Seven froze, a murderous flash on his face.

At such a point, it is impossible for No. 7 to act separately from Song Qingxiao, and both of them know this.

The collapse of the laboratory, and several trialists were forced into such a sealed space as the laboratory, which in a way was exactly what Seven meant.

Among the three lucky ones, No. 7 thinks that Song Qingxiao is extremely cunning and deep-minded, and compared to the elusive No. 3, she is undoubtedly more difficult to deal with.

No. 7 was not worried about No. 3's ability, because as Song Qingxiao expected, No. 7 was hit by a strange fish on the ship that day, and his body had already begun to mutate.

Number Three was also attacked by a giant wolf, and both of them were probably eager to complete the task and return to the real world at this time to solve the abnormalities of their bodies.

Only Song Qingxiao was not injured, she was not in a hurry, so at such a moment, she could still seek stability.

No. 3 and No. 7 have the same purpose, they both want to kill each other immediately, so they can't wait to stare a few trialists under their eyelids, so it's convenient to do their hands and feet, and it's impossible to separate.

However, Song Qingxiao is the most unstable factor, once she is out of her sight, it is not easy for No. 7 to find her again.

How could she allow that to happen? Therefore, Song Qingxiao gave her a nail to touch, and even if No. 7 was dissatisfied, he could only endure this breath.

At present, No. 7 didn't dare to say 100% that he could beat her, and he couldn't go his own way, so she could only stand in place, and endure depression as she watched Song Qingxiao draw a huge rectangle on the glass.

The cut glass can be pushed down, even if there is a problem with the door's sensing device, there is danger at that time, and there will be no panic when you exit.

After doing all this, Song Qingxiao followed No. 7 and the others down the stairs.

Some of the desks in the lab were cleaned, and some of the cabinets were emptied, leaving only some lab equipment on the countertop.

There are large and small glass experimental tanks inside, which are somewhat similar to Mr. Zhou's makeshift laboratory that I saw when I was on the ship.

But the only difference is that the glass tanks in Mr. Zhou's ship's laboratories contain all kinds of animal specimens, but these experimental tanks are empty.

"It seems that when Changsheng Technology withdrew, the experimental samples were also moved."

Seven leaned closer to a cylindrical test trough and sighed.

The experimental tank contained large and small threads, densely intertwined, like a ball of twisted snakes.

The lamppost inside emitted a faint glow, illuminating Seven's face gloomily.

"Not necessarily."

Song Qingxiao let go of her spiritual power, her eyes fell on those tables, and No. 3 followed behind her unhurriedly, maintaining a distance suitable for a sneak attack.

She obviously hadn't given up trying to hit Song Qingxiao's heart hard, and Song Qingxiao lowered her eyelids to hide the killing intent in her eyes.

When Seventh spoke, she replied nonchalantly, "There should be some left, otherwise how did the mutation on the island come about?" ”

As soon as she finished saying this, Seven also accepted the sigh on his face and glanced into the distance.

The laboratory is really not big or small at the moment, and the sporadic lights continue for a long time, so that there is no end in sight, until the end merges with the darkness.

"You say......" Seven rolled his eyes, and suddenly spoke again:

"Mr. Zhou is holding the evolution potion, why don't you inject it, and you have to rush to the laboratory? Is there anything left in the laboratory related to this evolutionary potion? ”

She had the right question, but the person she was really talking to should be Three, not herself.

Song Qing pretended not to hear her words, and bent down to touch the table.

The table was covered with a layer of dust, and in the dark environment, she pulled out a fresh mark with a touch.

In addition to the dust, there are no traces of biological visits, and after the laboratory was abandoned, it was not destroyed, and it still maintained the appearance of Zhou's scientific researchers retreating at that time.

"The medicine in the box, there may be certain conditions for injection, No. 3, what's the use of holding it in your hand?"

No. 7 watched Song Qingxiao's movements and muttered to himself.

"Come out, let's cooperate, let's go out together first. Your abilities won't last long, and you've followed us all the way, and you should have heard my conversation with Five before, and you know that there is danger here, so why don't you save some strength? ”

Her voice rang out in the room, and she was echoed by herself.

Song Qing walked straight forward, the research results here had been emptied, and a few minutes later, several people had finished turning this laboratory, and no traces of other creatures were found.

Changsheng Technology's laboratory is divided into different research areas in the form of stairs, and after each floor, you will descend several steps to enter the new laboratory.

About two quarters of an hour later, Song Qing and the others were already far away from the elevator when they went downstairs before, and they should have gone deep into the hinterland of the island.

Until now, the trialists had not found a way out of the laboratory, as if they were still sinking deeper and deeper.

Song Qingxiao roughly calculated in her heart, from the past to the present, even if they are not slow because of caution, but there is no doubt about the size of this laboratory.

Seven was still chattering, breaking the silence and bringing some popularity to the eerie environment, but it also brought noise, disturbing her judging the environment from the sound.

'Boom...... Knock ......'

"Three, come out, your ability ......" Seven was still talking, and some strange voice was muffled by her voice.

It was as if something had touched the glass, making a faint crashing sound, and the sound was heard far away through the empty mine's laboratory, faintly absent.

Song Qingxiao's expression changed, and she listened carefully, the previous impact sound was like an illusion generated by her extreme nervousness, she listened to it for a long time, and only heard the chirping of No. 7.

She stopped, held her breath, and after about ten seconds, the voice came again: 'Knock......'

It's not her delusion!

This voice is extremely soft, if it weren't for Song Qingxiao's full mental power, and because the environment was too quiet, she might not be able to catch it.

No. 7 was still talking, and Song Qingxiao always felt that there was a fishy stench in the air, like the smell of something rotting, mixed with the smell of blood and the smell of the ocean, and the dull and moldy smell of the laboratory, forming an extremely uncomfortable feeling.

She 'swished' in the direction of looking back, there were also sparkling lights, and there was no way back, as if several people were in a sea of starlight, there was no end ahead, and there was no way back.

Song Qingxiao had a strange feeling in her heart, and at this time, her heart was also up and down, and she was a little uneasy.

"What's wrong?"

Noticing her strange appearance, Seven couldn't help but ask.

"Shh She coldly 'shh

No. 7 closed his mouth and asked Song Qingxiao with his eyes, but he couldn't get a response from her.

The sound stopped abruptly, and the suppressed breathing sound of 'whew, bang, bang' combined with the heartbeat of 'bang, bang, bang', and the blood vessels in the mind were beating suddenly, forming a special melody.

In the midst of these sounds, an out-of-tune 'dong ......' sound sounded suddenly, and this time the quiet No. 7 was also heard very clearly!

'Goo-dong'!

The sound of Seven swallowing saliva is heard, and the sound she makes is very noticeable because of the extreme silence around her.

At this time, No. 7 couldn't be embarrassed, because the moment she heard the sound of 'dong', her scalp was numb, and goosebumps stood up on her body.

Large strands of sweat seeped down her erect hair, and traces of sweat soaked from her forehead at a visible rate, soaking the hair on her face into strands.

Something was hitting the glass, this was the home base of Immortal Technology, the center where Alcatraz was made.

There's a powerful mutant creature that has evolved to the 'Emperor' level, and its presence causes other mutated creatures to flee!

At this time, this voice may have come from it, intended to warn the three people who intruded into its territory!
