At four o'clock in the morning, it was the most quiet time in the research institute, and this sudden alarm woke everyone up from sleep.

Dr. Chen was even more shocked into a cold sweat, and he was so frightened that he immediately got up from the bed.

My God, Dr. Xiao Bai is still a few hours away from the research institute, and the highest level of alarm sounds at this juncture, isn't it killing him!

There was a wail in his heart, but Dr. Chen's movements were so quick that he couldn't even wear shoes, and his first reaction was to rush over and get the chip controller.

After suffering the loss last time, Dr. Chen now carries a chip controller with him.

After holding the chip controller, Dr. Chen picked up the walkie-talkie, which was flashing non-stop.

The voice of the security captain came over the intercom: "Dr. Chen, Dr. Yao, she escaped with No. 9." ”

Dr. Chen's eyes widened: "This is impossible! ”

How is this possible!

How could Dr. Yao possibly defect to the Institute?

There's no reason at all!

Besides, even if Dr. Yao did defect, how did she untie Nine's bracelet and take Nine to avoid the attacks of those weapons in the corridor?

The security captain was arranging for his subordinates to go to various elevator entrances to block the blockade, and took the time to explain to Dr. Chen: "At 3:50 a.m., my subordinates told me that Dr. Yao was going to feed medicine to Nine. ”

"At first, I didn't suspect Dr. Yao's actions, and in the spirit of being cautious, after a few minutes, I asked Dr. Yao on the walkie-talkie if he had left, but I didn't get a response from my subordinates."

This anomaly alerted the security captain to the moment.

He immediately sent someone to press the alarm, and personally went to the room where Nine was being held to check, at that time Nine was gone, only his two teammates were lying unconscious on the ground.

"Dr. Yao, no, where is Yao Rong now?" Dr. Chen didn't care about how Yao Rong escaped, and instead asked the most critical question.

"We're looking for her too."

"What about surveillance?"

The security captain looked at the screen in front of him that was divided into pieces, and said with a wry smile: "I'm in the monitoring room now, but I've checked it, and the monitoring is not abnormal at all." "The other party has already invaded the surveillance, and it is impossible to grasp the whereabouts of the other party through surveillance.

Dr. Chan cursed.

"I'm already staring at the elevator hall, though. My authority is higher than Dr. Yao's, as long as they take the elevator to the fifth basement floor, I will trap them in the elevator at the first opportunity. Just ......"

The security captain paused.

Although the next words are a little long and others will destroy their own prestige, but who calls it so.

"Nine was able to subdue two of my teammates in a single look, and even if I could trap them, I wouldn't be able to subdue Nine. I need a chip controller. ”

Dr. Chen said cheerfully: "No problem, the chip controller is in my hand." You're in the monitoring room, right, I'll give it to you. ”

The security captain hurriedly stopped: "Dr. Chen, this is too risky, I'd better let someone get it." ”

Now Yao Rong and No. 9 don't know where they are, and Dr. Chen's place is not very far from the monitoring room, but what if he is unlucky and happens to run into it?

"Your subordinates can't beat the nineth, it doesn't make a difference whether he takes it or I take it."

Besides, as the leader of the research institute, he must rush to the monitoring room as soon as possible.

Dropping this sentence, Dr. Chen grabbed the chip controller in one hand and the walkie-talkie in the other, and opened the door.

When the door was pulled, he was still thinking about where Yao Rong and No. 9 had fled now.

Then, in the next second, Dr. Chan knew the answer to his question.

Yao Rong and No. 9 were standing at his door waiting for the rabbit.

The speed at which the patrol officers discovered the anomaly was much faster than Yao Rong imagined.

When the alarm stopped ringing, Yao Rong and Lu Fei had just run to the door of the elevator room.

According to normal logic, Yao Rong should now hurry up and take the elevator to the fifth floor underground, and then race against time to escape from the fifth floor underground while the security is not fully in place.

But Yao Rong only thought for a second before changing his mind.

Her authority in the institute is very high, and there are people who have higher authority than her.

For example, Dr. Chan and the security captain.

Today, the security captain is in charge of patrolling, and the alarm will go off so fast, nine times out of ten, it is his handiwork.

It only takes a few seconds to get from the second basement to the fifth basement. These few seconds were enough time for the security captain to use his authority to override her authority and trap her and Lu Fei in the elevator room.

If you want to take the elevator to the fifth basement floor smoothly, the best way is, of course, to hold the person with the highest authority in the research institute hostage.

Since the lowest floor was destroyed, not only Yao Rong changed the room he lived in, but the researchers who originally lived on the lowest floor also moved to the second basement floor.

Dr. Chan lives in the house at the end of the hallway.

Yao Rong and Lu Fei came to the door of Dr. Chen's room, clenched their fists and planned to break the door directly and violently, but in the next second, the door opened, and Lu Fei's fist was unable to retract and rushed to Dr. Chen's face.

Because he didn't hit the vital point, Lu Fei's punch did not make Dr. Chen unconscious on the spot, but it also made Dr. Chen dizzy, and he held on to the wall for a long time.

Looking at Dr. Chen, who was almost sent under his fist, Lu Fei was also a little confused.

Worst.

What if he smashed Dr. Chan and Dr. Chan's facial recognition failed for a while.

Secretly complaining in his heart, Lu Fei stepped forward to subdue Dr. Chen.

Dr. Chen endured his dizziness and pressed down the chip controller before Lu Fei took the things in his hand.

And then......

Well!?

How could there be no response!?

Dr. Chen looked sharply at Yao Rong, who was standing behind Lu Fei.

He once opened the permission of the chip controller to Yao Rong.

Later, the matter was quickly resolved, and he took back his authority and did not take the matter to heart.

But now the chip controller is out of order......

Obviously, the other party must have done something to the chip controller during that time.

"Dr. Chen, please cooperate with us." A scalpel slipped from Yao Rong's sleeve and was held in her hand against Dr. Chen's neck. With a little force, blood escapes from the wound.

After warning Dr. Chen, Yao Rong glanced at Lu Fei, and the corners of his lips rose.

"Lu Fei, go open the way."

"Open the way to the elevator room directly to me!"

At this point, the hallways of the dormitory area were already bustling with activity, with researchers opening the door to check on the situation, and security guards armed with guns searching for it.

As soon as Yao Rong and Lu Fei moved towards the elevator room, they were discovered.

"They're there!"

As soon as a slightly fat security guard pointed at Lu Fei and shouted, he saw that the young man who was still a few meters away from him flashed to his side like a ghost, and then ...... Then he just fell down.

The fat security guard didn't know how he had fainted, but his companions could see it clearly.

At the moment when Lu Fei came to the fat security guard, he directly smashed his fist into the fat security guard's chest, kicked the fat security guard who was blocking the way to the side, and completed the close fit with the fat security guard.

Guns?

What is the use of a gun.

At Lu Fei's speed, how many people will be able to target him?

After easily solving the two security guards, Lu Fei was about to deal with the third person when he suddenly tripped over a vine.

The vines that appeared out of thin air grew in the wind, climbing up from Lu Fei's ankles, and restraining him.

This is obviously a mature set of tactics, and when Lu Fei is fixed in place, other security guards seize the opportunity to target Lu Fei.

Bullets flew in the air.

But—

All of them were lost!

Only a dozen levels of vines couldn't entangle Lu Fei at all, and under his attack, the vine blood bar was instantly emptied, and he also took advantage of the situation, dodging bullets, and rushed towards the one who released the wood-based ability like an arrow off the string.

With a wave of his right hand, a large number of seeds fell into the air, taking root and sprouting, turning into a sea of thorns covered with barbs, enveloping Lu Fei with fangs and claws.

Before the other security guards could breathe a sigh of relief, the wood-based ability suddenly exhaled with a headache, and the ability was overconsumed and collapsed, his face as white as paper.

Without the nourishment of the ability, the thorns withered, and Lu Fei tore the withered vine that wrapped around his arm and continued the attack.

In the process of Lu Fei's fight, Yao Rong held Dr. Chen forward step by step, without stopping or slowing down.

In this way, she passed through the corridor of Lu Fei at a uniform speed, and smoothly came to the elevator, and opened the elevator door with Dr. Chen's authority.

After learning that Dr. Chen had fallen into Yao Rong's hands, the security captain clearly realized that the elevator could not trap Yao Rong and them.

He used the walkie-talkie to get all the security guards on the other floors to come to the fifth basement floor.

The people who entered the Ninth Research Institute have never been able to escape.

The first precedent must not be in his hands.

Putting down the walkie-talkie, the security captain stood at the highest point of the fifth basement floor, looking at the elevator doors that had been surrounded by layers.

He silently counted down in his mind: five seconds, four seconds, three seconds...... It's time for the elevator doors to open.

However, five seconds after five seconds, the elevator door that had reached the fifth basement floor never opened.

"What's going on?" The security captain was so angry that he smashed the walkie-talkie in his hand, "If they don't open the elevator door, then just blast it open with a weapon!" ”

Just as the security captain's voice fell, the elevator door opened without warning.

A man was thrown out of the elevator.

Before everyone could see the person who was thrown out, the power supply on the fifth basement floor was cut off by the system, and all the lighting equipment went black in an instant.

"Oh no, someone ran out of the elevator!"

"Bomb with your weapons!"

"The person who was just thrown out of the elevator should be Dr. Chen, what if you accidentally bomb Dr. Chen."

"Who's going to the electric room to see."

The voices of gossip were mixed together, and the scene was chaotic.

Someone tried to chase the two figures who ran out of the elevator, but they were knocked out of shape by their companions next to them, and by the time he stabilized again, the two figures had completely disappeared into the darkness.

"What about the fire system, summon a fireball for lighting!" An ominous premonition rose in the security captain's heart, and even if the fireball drove out the darkness, it wouldn't make him feel better.

From beginning to end, his actions were led by the nose.

The other party counted almost every step of reaction he would take.

He was full of confidence before, but now he has begun to doubt: can he really keep Yao Rong and No. 9......

After a few changes in his gaze, the security captain put this question behind him and grabbed a subordinate casually: "Go to the power room to restore the power supply, go quickly!" Everyone else comes with me! ”

With the combat power of the nineth, his subordinates can't beat him alone, and instead of being broken by the other party one by one, it is better to catch turtles in an urn.

Therefore, the security captain did not spread his forces to find Yao Rong and No. 9, but directly took everyone to guard the exit.

Anyway, as long as Yao Rong and No. 9 want to escape from the research institute, this gate is the only way for them.

Yao Rong and Lu Fei bowed down and quietly hid behind a nutrition cabin.

This nutrition pod is far away from the door, but the evolution liquid that Lu Fei has injected has specially improved his eyesight, and this distance and darkness are completely insignificant to him, and he can see everything at the door clearly.

After observing for a while, Lu Fei turned his head to look at Yao Rong.

In this case, it is definitely impossible to break through by force, and it must be outwitted.

So, Dr. Yao on.

"Let's wait." Receiving Lu Fei's gaze, Yao Rong said warmly.

What are you waiting for?

As if in response to Lu Fei's doubts in his heart, three loud noises came from below in succession, causing the floor under Lu Fei's feet to shake several times, and the surrounding dust flew everywhere.

The deer is not slightly raised on the tip of the eyebrows.

Is this what Dr. Yao is waiting for?

But now that they've fled to the fifth basement, how will the explosion below help them escape?

"Do you remember where I put the flask?"

Of course Lu Fei remembers.

He looked up at the nearest vent.

The security captain was also staring at the ventilation ducts.

He has a wind supernatural under him, and he has a keen sense of the wind, and after the explosion, his men come to tell him that the wind flowing in the room has been affected.

The three explosions just now caused incalculable damage to the ventilation ducts.

The ventilation of the institute is all done by ventilation ducts, and now that the ventilation ducts have been destroyed, the oxygen supply in the institute has become a big problem.

They can hold on for a short time, but if it lasts for a long time, everyone in the institute may have a severe hypoxic reaction.

"It's trying to create chaos and force us to open the door." The security captain gritted his teeth.

You can't change the air by the ventilation duct, so you can only use the most primitive way to change the air.

"Captain, the closer you get to the place of the explosion, the more serious the damage to the ventilation ducts. The explosion is supposed to have occurred on the second basement floor, and we need to inform the researchers on the second basement level to evacuate immediately. ”

The security captain became more and more irritable.

He had a hunch, which must have been expected by the other party.

But even if it was the other party's trap, he had to jump down with his eyes closed. Each of these researchers was more precious than the other, and he couldn't possibly watch them die.

"Let them retreat to the fourth basement first, and then ......"

The security captain couldn't go on.

And then what to do.

Retreating to the fourth basement level will not solve the problem of lack of oxygen at all.

"Captain, we have more concerns than them, we still have to find them as soon as possible." Subordinates are helpless.

After the ventilation duct was blown up, they simply couldn't wait for the rabbit anymore.

Once again, the security guards who had been gathered together spread out in a net.

However, after suffering so much, this time their movements are very focused on echoing each other, and if one person is suddenly attacked, the people on his left and right can give an early warning at the first time.

Lu Fei looked at Yao Rong again and asked her what she was going to do next.

"At this point, it may really need to be played."

"If I can force the gate open, can you fight your way out."

If Lu Fei's strength is not restored, Yao Rong will choose to use other methods to make the situation more and more chaotic, and then escape with Lu Fei in the chaos.

However, if the strength is sufficient, there is no need for any conspiracy.

All he had to do was rush to the door, and she would use the last chance to open it, and the two of them would be able to get out of this hellish place.

Seeing Lu Fei nodded, Yao Rong smiled slightly: "Then you can take me and kill me directly." ”

"Remember, your first goal is not to knock them down, but to get close to the gate. Don't think about anything later, listen carefully to my command, and we will rush to the gate in one breath. ”

Lu Fei stood up, moved the duffel bag that was originally behind him to the front, and squatted down with his back to Yao Rong.

Yao Rong understood what he meant and lay on his back.

Lu Fei is only fifteen years old, and his body has not fully grown, but he is also one meter seventy-two tall, which is enough to carry Yao Rong. It's just that the head is too fast, and the body looks slender and thin.

Just looking at the appearance, no one would have thought that this muscular body contained such terrifying power.

After Yao Rong was lying down, Lu Fei stepped and rushed directly towards the gate.

"They're there!"

"Stop them!"

"They're running in the direction of the gate, retracting, and immediately retracting!"

Lu Fei's sense of hearing is very keen.

Or should it be said that his sense of hearing is no longer in the category of normal humans.

He can hear all sorts of fluctuations that humans can't hear.

The bullets that came from behind him, the ability attacks that lunged at him one by one, always dodged him. If he can't avoid it, he will fight back.

But whether it's dodging or counter-attacking, he's moving forward.

He's not smart enough, but he's good enough to listen to smart people.

Dr. Yao asked him to come close to the gate, and he kept moving forward, not taking a step back.

Because of this absolute stubbornness, Lu Fei gradually got injured on his body, but his actions did not slow down at all.

"Rush into the crowd so they can't target you."

Hearing Yao Rong's words, Lu Fei began to consciously choose a place with many people to run when he was running.

These people will be beaten by him in front of him, and they will not be able to stop his way at all, and they can be used as a shield for those who control a wide range of high-lethal weapons to take care of.

"You can find cover for yourself." Yao Rong continued to remind.

Lu Fei's actual combat experience is too poor.

Just like sitting on a treasure trove but not being able to use it at all, Lu Fei's physical potential has been developed to the extreme, but he can only use the simplest fists, palms, and legs, relying on strength and agility to attack, and has no skills at all.

But......

If Lu Fei's actual combat experience was too good, Yao Rong felt that he might not be very happy.

This shows that he must have done nothing good behind her back before!

Using an empty nutrient pod to avoid a bombardment, Lu Fei had already ducked behind another bunker when the nutrient pod was blown to pieces.

"Ahead of you are the security captain and Dr. Chen. Pretending to be physically exhausted, he broke through to them and forced them back. ”

Lu Fei didn't have to pretend, he was already tired.

Tiredness passed from his brain to his limbs, his breathing became more and more rapid, there was a faint tearing sensation after overuse of his muscles, the back of his fingers was bleeding from the repeated attacks, and the injuries he had just received continued to bother him, but he was still advancing.

He and Dr. Yao were only five meters away from the gate.

At this last moment, you have to hold on no matter what.

This was the first time Dr. Chan had seen the Nine, who had erupted in a conscious state.

His eyes were both fearful and faintly fanatical.

Since the end of the world, people have called the game bracelet a "miracle", but in Dr. Chen's opinion, the number nine in front of him is the real miracle.

Compared with the creation of "gods" by heaven, of course, man-made "gods" are more shocking.

But soon, Dr. Chan came back to his senses by the terrible reality in front of him.

He increased his breathing, and then he felt that his breathing was a little smoother, and the oxygen level in the research institute had dropped to the point where it could make his body uncomfortable: "Captain Zhou, are you ready?" ”

"Alright." The security captain looked back at the tightly closed door made of countless special materials, "The limit voltage has been added to the door, as long as Nine dares to smash this door with his fist, the first time he touches the door, Yao Rong will be electrocuted, and Nine will also be knocked unconscious." ”

"That'll do."

Dr. Chan doesn't care what kind of punishment he will be punished afterwards.

All he knew was that he had to keep Nine.

Keep the Nine, and there will be room for maneuver.

"Dr. Chen, you just woke up, hurry up and go to the side to rest. My subordinates and I would fight and retreat, and let Nine approach the gate without a trace. The security captain said.

Dr. Chan touched his freshly bandaged head and left the place with a heartfelt attitude.

The security captain turned his right hand, and golden light flowed out from the game bracelet on his wrist, turning into a spear and pointing directly at Lu Fei.

Lu Fei originally thought that it would be difficult to break through.

After all, his state has declined now, and he still has to take care of Dr. Yao on his back.

But when it really came to an encounter, the intensity was quite intense, but it didn't seem to be as difficult as he imagined.

"When you get to the gate for a while, don't reach out and touch the door. As soon as the door opens, you immediately run to the east. ”

"You know the east, if you don't recognize where it is, you run to the place where the sun rises."

The sound of breaking the air burst, and Yao Rong's voice was clearly captured by Lu Fei.

Lu Fei almost missed and threw Yao Rong out.

Although he really couldn't tell the difference between the directions of the southeast, the northwest, but the sun rising in the east was common sense, okay, why did she emphasize it in such a serious and solemn tone!

Damn!

With a fire in his heart, Lu Fei sprinkled all his anger on the security captain.

Smashing the spear conjured by the security captain, and shattering the shield he conjured up, Lu Fei finally came to the heavy door that completely separated the research institute from the zombie world outside.

He walked briskly to the door and held out his right hand.

At this moment, the attacks from behind him were suspended.

A few slightly expectant glances landed on his palm.

It's almost over.

Deer didn't think so.

The security captain and Dr. Chan thought the same thing.

When Lu Fei's fingertips were about to touch the gate, this gate, which had to rely on special instructions to open, opened little by little in front of everyone's eyes.

If the stars and the moon are absent, the morning light breaks through the clouds, illuminating the barren ruins of the walls in all directions, the zombies in the distance howl endlessly, and the rain is constantly noisy. The wind blowing in my face smelled of decay and disgustingness.

Everything looks so bad out there.

But it's real enough, and it's free enough.

Lu Fei carried Yao Rong on his back, facing the direction of the rising morning light, running faster and faster.

And the security captain and the others who stayed in place, after being stunned, all went crazy!
