The white fluff that looked petite on the little white mouse was all over the big white mouse's body like steel needles at this time, the black sesame-sized eyes also turned scarlet, and the fleshy and non-threatening claws became sharp and sharp, and the most powerful Threatening teeth—there was a faint cold light on the rat's mouth.

Qiao Yiqiao knew that this battle was inevitable.

In the next second, the rat that squeezed into the door frame also found its target in the debris of the door——Qiao Yiqiao. With a kick of its legs, it quickly rushed over.

The huge body did not make the big white rat in front of it lose its due agility, but instead increased its destructive power countless times. After the outer door was shattered into slag, the inner wall was also torn under the impact Slag.

In the broken metal shadow, Qiao Yiqiao stood in place, his eyes behind the transparent goggles did not blink, he tightly clenched the metal stick in his hand, and swung it out the moment the big white mouse jumped in front of him.

Fifty times the power - even the rats infected with Y cells can't bear it. After all, they are flesh and blood. Even if they are mutated, there are limits to what they can bear. The strength of the rats is obviously inferior to Qiao Yiqiao. Knocked back by metal rods.

But that's all. The rat took a few steps back under the impact of the powerful force, hit the metal wall, and made a huge roar, but it was just repelled. Qiao Yiqiao clearly saw that the rat's body had only It's just a bloodstain, it is estimated that the injury is only the fur.

But Qiao Yiqiao, under the impact of the rat, took an unknown number of steps back, and then hit the wall, his internal organs were in pain.

With just one blow, Qiao Yiqiao knew that the monster in front of him was invincible.

Maybe his strength is better than that of the white rat, but the white rat has rough skin and thick flesh, so it will not die even if it is hit by a few sticks. be yourself.

Qiao Yiqiao tightened his lips, and asked Asa, "Did the Y cells have to be the brains of rats?"

Of course, they have discussed the last step of this plan many times. There is no doubt that the original Y cells are in the rat, but not every part of the rat infected by the Y cells can become the original Y cell. Only the initial mutation, the dominant The mutated brain cells that kill all Y cells are the source of all Y cells' disasters, that is, the original Y cells.

But at this time, Qiao Yiqiao wanted to confirm again. After all, what was originally estimated to be just a small white mouse has now become a big white mouse. The difficulty of obtaining the original is almost geometrically increased. If it can be replaced by another——then The blood belonging to the rat on his stick contained Y cells.

It's just that this is obviously not acceptable, Asa shook his head, dispelling Qiao Yiqiao's idea of ​​taking a shortcut.

The blood belonging to the rat on the stick is not good, so he can only find a way to get the brain of the rat. Qiao Yiqiao took a deep breath, and when the rat was knocked out of the head by a stick, he threw Asa into it. The ventilation holes on the head.

Asa knew that he was also dragging Qiao Yiqiao's hind legs here, so he didn't say much, but just crawled into the ventilation hole cooperatively, and Qiao Yiqiao faced the rat again after Asa was safe.

The rat also woke up from the heavy blow to the brain at this time, and after waking up, he was furious. He never expected that he was actually injured by the weak food in front of him. Feeling the bloodstains on his body, he thought that if he wanted to repair these The energy spent made the rat even angrier, and rushed forward again.

The scarlet mouth pounced on Qiao Yiqiao, and Qiao Yiqiao could even see the interlaced teeth in that mouth, sharp and full of blood—this blow was obviously impossible to fight recklessly, and Qiao Yiqiao quickly dodged.

"Boom!" The rat crashed into the computer desk.

Just when Qiao Yiqiao thought he had dodged a blow, he didn't expect that behind the white rat, a long tail slammed towards him.

The long white tail whipped towards Qiao Yiqiao like a long whip. Qiao Yiqiao dodged the first blow, but failed to dodge the second one. He barely lifted the stick in his hand and was thrown flying.

The bloody smell overflowed his mouth and nose, Qiao Yiqiao swallowed a mouthful of blood, stood up with his back against the wall, and the white rat on the opposite side shook his head, and rushed over again as if nothing happened.

Qiao Yiqiao had no choice but to roll to the side and swing the metal stick in his hand again.

This time, the metal rod collided with the rat's tail, which was repeating its tricks. Only a wailing sound was heard, and the rat jumped up quickly, creaking.

And Qiao Yiqiao also came to the center of the house by the shock force of this blow.

That is, under the vent.

"Rope!" Qiao Yiqiao shouted.

A special rope was quickly dropped from the position of the ventilation hole-this was stuffed into Qiao Yiqiao's arms when he threw Asa into the ventilation hole before, and it happened to be used at this time.

So before the rat recovered from the severe pain, he saw the food in front of him crawling up the rope to the ceiling, trying to escape.

Anxiety caused the rat to lose its prudence—or maybe it didn't have much wisdom. In desperation, the rat rushed directly towards the ventilation hole where Qiao Yiqiao was.

This is exactly what Qiao Yiqiao expected.

Qiao Yiqiao quickly avoided where he was originally, and watched the white rat's head rushing straight to his original position. Its hard teeth hit a big hole in the metal plate, and the long-open mouth bit the metal block into pieces. end.

The sturdy rat's head tore through the ventilation hole, and the entire ventilation duct was on the verge of collapsing due to this heavy blow. The rat's head was stuck on the ventilation hole, and the struggle made the entire duct shake.

And this is exactly the opportunity Qiao Yiqiao was waiting for.

The rat's paws were still struggling, Qiao Yiqiao knew that this would not trap the rat for long, and he had no time to waste, so at the moment the rat got stuck, Qiao Yiqiao made a move.

The metal stick used for swinging has become a sharp weapon at this moment. With the support of Qiao Yiqiao's strength, it pierces the rat's eyes almost effortlessly. The rat roared angrily, but couldn't help it. Stop Joey Bridge from deeper and heavier insertions/insertions.

The blow went straight to the brain.

The pain and hitting the vital point made the rat struggle desperately. Qiao Yiqiao had no time to cause more damage to the rat, completely destroying the rat's brain, before the rat broke free and fell from the ventilation hole.

In the end, Qiao Yiqiao tried his best to withdraw his metal stick, so that the blow would not come back in vain.

The white rat was howling below, but Qiao Yiqiao had already taken Asa and fled into the ventilation duct quickly. He was careful not to touch the metal rod in his hand, and was even more careful to protect it. Although the blow did not kill Rat, but it also achieved the most important goal of Qiao Yiqiao - the original Y cell!

The brains of the white rats are here!

Just wait until they reach a slightly safer place, then they can make a medicine to suppress the mutation of Y cells, so that the whole research institute can return to normal.

Qiao Yiqiao chose Director Li's office. The infected people in this place have been cleared out and the door is locked. As long as there is no loud noise, the infected people cannot be attracted temporarily. It is the best place.

The prepared medicinal solution was prepared early in the morning, and it was safely placed on Asa's body. Now it is only necessary to carry out a certain proportion of experimental fusion of the two.

So, in Director Li's office, the production of the drug that inhibits Y cell mutation was officially started.

Asa's eyes were very focused, and he almost didn't need a test tube to measure. He just used his hands and naked eyes to prepare the solution layer by layer. Qiao Yiqiao watched with bated breath. 1 minute, 2 minutes... 10 minutes, finally, the original red liquid medicine Gradually morphed into an odd green with white brain pulp.

"Success."

Qiao Yiqiao's mouth moved unconsciously, wanting to laugh, the inhibitor was finally configured, he should have laughed, but at this moment, he couldn't laugh, only showing a strange expression.

Asa didn't say anything, just hugged Qiao Yiqiao gently, and then poured the medicinal liquid into the vaporization device.

He took Qiao Yiqiao's hand and put it on the button of the gasification device, "Don't be sad, now, press it, the liquid medicine will evaporate in the air of the whole institute, and all the monsters will disappear."

Asa wanted to press Qiao Yiqiao's hand, but Qiao Yiqiao's hand stayed on the button and did not press it.

Asa was a little puzzled. Looking at Qiao Yiqiao in his arms, he looked up and said, "If the monster disappears, what about you? Will you disappear?"

Asa was stunned, he didn't expect Qiao Yiqiao to ask this question, "Why do you ask this?"

Qiao Yiqiao smiled wryly, "You are also infected with mutated Y cells, right?"

So even though he was Asa, in order to avoid infection, he didn't have any too much contact with Qiao Yiqiao except for lip service.

Asa didn't know how Qiao Yiqiao knew. He was possessed by Dr. Yan, and he almost never showed his monster characteristics. How could Qiao Yiqiao know?

But looking at Qiao Yiqiao's expression, he knew that he had been exposed.

Asa said silently, "I am."

The button was under his hands, but Qiao Yiqiao suddenly didn't dare to press it at this moment. He had tried so hard to resolve the dungeon crisis, but now, Qiao Yiqiao remained motionless.

It's just that Qiao Yiqiao didn't move, but Asa made the choice for him.

A hand bypassed him and pressed the button that Qiao Yiqiao should have pressed.

Small green smoke rose in the entire room, and then disappeared in the air. Qiao Yiqiao seemed to hear the sound of monsters wailing and falling to the ground in the corridor outside.

And Asa in front of him also smiled and fell to the ground.

The center of the eyebrows went from hot to cold, and an invisible green mist filled the entire research institute. They started from the fourth floor and spread to the third floor, fifth floor, second floor, sixth floor, first floor, and seventh floor. ...

All the monsters fell to the ground at the moment when the green mist invaded, and the white rat returned to its original appearance. The surviving players and Millie wept bitterly in surprise. Outside the laboratory, it seems to be no different from before.

No, there is still a difference.

Without Dr. Yan and those npcs from the Security Section, they turned into monsters and fell forever.

All the players were dizzy before their eyes, and Qiao Yiqiao once again experienced the same scene as the first dungeon before, and they "saw" their original destiny.

The Y cells mutated out of control, and a small number of survivors gathered, but this time, they did not have Qiao Yiqiao, so the experimenters and researchers in the institute could only flee to the seventh floor in a hurry, seeking Dr. Yan's help.

However, Dr. Yan has turned into a monster long ago, they finally only found a set of equipment and experimental materials in the laboratory, which said how to end the Y cell mutation, they had to continue to run and hide, they hid on the sixth floor, frozen Some of them died of starvation and hid on the fifth floor, some of them starved to death and hid on the third floor. The monster broke through the bulletproof glass and hid in various places, facing all kinds of deaths.

Finally, they managed to reach the fourth floor and found the original Y cells, but unexpectedly, the mice had already grown so huge that they couldn't get the original at all, and they were still found in the ventilation ducts, becoming infected A member of the group was completely wiped out and wandered around the research institute together.

In the end, the scene stayed in the reception hall on the first floor. A smashed door was open, and an infected person wandered out. Outside was the modern world full of traffic.

All the players' eyes went dark, and Qiao Yiqiao heard a faint voice in the darkness.

"Congratulations to player Qiao Yiqiao for clearing the dungeon "Y Experiment". The basic points for clearing the dungeon are 100 points, the points for clearing the dungeon five days in advance are 500 points, and the points for cracking the world view of the dungeon are 100 points. Looking forward to your next game."
