The overall feel of the core area is completely different, no longer those transparent building materials, but completely enclosed, without even a gap.

After opening the door with the level 4 ID card, I found that there was another door 2 meters away inside, and after opening it, there was another ...... inside

After passing through 6 doors in a row, I finally entered the research room inside.

"There are so many doors, why?" Bai Qi asked.

Ye Qi was also a little strange, "Normally, if there is a need, at most only two layers of disinfection, one layer of disinfectant spray, and then ultraviolet rays, there are so many layers here, I estimate that it is because the research carried out inside is very dangerous, far beyond the ordinary danger level, so there are so many layers of disinfection measures, but this amount is indeed a bit excessive, if there is really that kind of extremely dangerous virus or something, it is impossible to get it because of a few more disinfection tests." It's just a psychological comfort. ”

In fact, what is being studied in this so-called core research room, and several people have no clue at all, because it has been basically emptied, and there are some empty shelves, as well as some cabinets that have not even had time to close the door, and several computers have also been removed from hard drives, which are obviously deliberately cleaned.

After rummaging for a long time, they didn't find a single word about the research, so the three of them had to leave.

Just when he returned the same way, that strange feeling appeared in Bai Qi's heart again, and before he could tell Lao Zhang and Ye Qi, there was a sound from the ceiling, causing all three of them to look up.

A square ceiling fell off, revealing the black hole inside, and a white shadow skimmed by......

"Experiment mice!" Ye Qi recognized what it was at a glance, because he used to raise a lot of things when he was doing experiments, but the one he saw just now was relatively large, much bigger than an adult civet cat, and it seemed a little reluctant to shuttle through the compartment of the ceiling.

Lao Zhang listened attentively, the sound inside the ceiling was mixed, and there were obviously many things moving quickly, from far to near, "Run!" ”

Ye Qi and Bai Qi didn't dare to stay a little, and ran wildly according to the road they came, and the balance bike used for transportation had been thrown aside, and they still ran faster with their feet at this time.

The ceiling behind him kept falling, and a group of white rats fell from the sky like rain, crackling and falling to the ground, big and small, and the appearance was not the same, some were terrifying, some were deformed, but without exception, they would chase the three of them immediately after landing......

"Damn, got into the rat's nest? Lao Ye, do you need so many guinea pigs for your research? Bai Qi glanced back at the group of rats chasing after him, and complained.

Ye Qi gasped desperately, "It must not be necessary so much, it must have been a mouse that ran away when it was withdrawn, and the reproductive ability of the mouse is already very strong, probably."

It's even more exaggerated after the mutation! ”

Bai Qi manipulated the 4 swallow darts to attack the rat group behind him indiscriminately, and the result greatly surprised Bai Qi, the swallow dart just didn't enter the rat group, and he felt a very strong confrontation force, so that he couldn't control it freely.

I had to turn my head again and see countless rats wrapping the darts in them, and the sharp knives couldn't hurt them at all, on the contrary, if I listened carefully, I could hear the sound of them gnawing with their teeth......

In less than 10 seconds, it was completely connected to the 4 throwing knives.

Bai Qi was shocked, "This thing is a bit powerful!" The defense is amazing, and it can gnaw away my throwing knife, it's too perverted! ”

After saying that, he shot out the wolf king's fangs one after another, and this time it did have an effect, although it was also more laborious, but it was still able to penetrate the bodies of the mice.

However, just as the wolf king's fangs were shuttling among the rats, several large rats rushed out of the rat colony, and because they were too sudden, they were caught in their mouths before Bai could react.

After a few crisp sounds, Bai Qi was completely speechless, because the fangs of the wolf king, who could kill and injure S-class zombies, were bitten to pieces! What a powerful bite force, what a sharp tooth?

Lao Zhang also noticed this situation, "So fierce? Don't waste this energy, run quickly, you can't afford to spend it with these brutes. ”

Seeing that he was about to pass through the narrow passage, Lao Zhang slowed down.

Bai Qi was shocked, "What are you doing!?" ”

"Let Xiao Yezi go to launch the Gecko first, take advantage of the terrain of this corridor, block the rats a little, buy him some time, if he can't take off in time, it will definitely be over!"

Bai Qi thought for a while, the rats were chasing very deeply, with their sharp teeth, the gecko should not be able to hold it, "Old Ye, hurry up and start!" It's up to you whether you can run or not! ”

Although Ye Qi was worried that the two would be in danger after the break, as a professional soldier, he could still calmly face the current situation at such a critical juncture.

Bai Qi and Lao Zhang used their abilities at the same time to protect themselves with an energy shield.

Lao Zhang held two bone knives in his hands, and his momentum was like a rainbow.

In front of Bai Qi, there was a nameless sword tip, spinning wildly.

In the blink of an eye, a swarm of kung fu rats had already rushed in front of him.

Lao Zhang's hands waved rapidly, intertwining into an insurmountable knife net, and within the range that could be covered, no mutant rat could cross his barrier.

The mutations of these rats are different, and their abilities are also uneven, most of the mutant rats will be cut into two sections as soon as they come into contact with Lao Zhang's knife, some are only injured, and a small number will only be knocked away by the force of the impact, and will not be substantially harmed!

Bai Qi is simplified

Single observation, found that these mutant mice are divided into several different levels, and the size of the body has a direct relationship, the size of ordinary mice, is the weakest, a touch to die, and then the size of an adult cat, the body defense is stronger, before the gnawing swallow dart is this level, no matter how strong it is the size of a dog, the wolf king's fangs are destroyed in their mouths, there must be bigger and stronger, think about the big guinea pig in the city, it is a good reference, since the big guinea pig can grow to such a big size, these mice rely on a huge base, there are bound to be more powerful guys.

The tip of the nameless sword is like a meat clamp, invincible, and those big rats that destroyed the fangs of the wolf king will not be spared, but after they killed a few more rats of the same level, they actually began to deliberately dodge.

The large number of rats surging in the passage like a tide is an advantage, but at this time it has also become their disadvantage, and if you want to dodge, you will not be able to act too flexibly because of the obstacles of your kind.

Bai Qi took the opportunity to kill more than a dozen big guys.

"Squeak squeak!"

Just when Bai Qi and Lao Zhang were killing and the rats couldn't pass through the defense net of the two, several long and crisp rat cries came from the far end of the corridor.

Then, the side walls collapsed with a thud, and a large rat standing upright more than a man tall appeared in the sight of the two of them.

This guy looks very strange, the short hair on his body is as white as snow, there is no impurity, it looks very smooth, the limbs are abnormally developed, not as small as ordinary rats, and it is three nodes, the muscles are very obvious, the claws on the 4 fingers are 20 cm long, the tail is flicked back and forth, and the whip will leave a deep trace on the wall, which shows that the power is extraordinary.

The strangest thing is that it has a third eye in the center of the eyebrow! The sharp teeth in his mouth are glowing coldly, and it is estimated that the diamond diamond can be chewed by him!

Lao Zhang roared, "Capture the thief and capture the king first!" ”

Resisting the rat swarm made Lao Zhang unable to be distracted, from this short tens of seconds, he felt that most of these rats were brainless charges, and they were not afraid of death, and now this super big rat appeared, obviously more aggressive, obviously under its command! If the situation is allowed to develop like this, it is said that these rats have been blocked, and it is estimated that the comfort of the two is a problem.

This is like marching and fighting, killing the leader of the general, so that the whole army loses good command, and naturally it will be like a plate of scattered sand, self-defeating!

Bai Qi understood what Lao Zhang meant, and with a thought, the tip of the nameless sword shot towards the huge mouse, and under the crisis, Bai Qi had already exerted his strongest strength.

If it weren't for the fact that he controlled the tip of the nameless sword and had the connection of spiritual power, I am afraid that Bai Qi would not be able to see through the trajectory of the nameless sword tip, in order to have a miraculous effect, Bai Qi condensed his mind and let it flash back and forth in a zigzag shape.

Lao Zhang watched Bai Qi attack, and secretly said in his heart that he had made great progress, and he would deal with it by himself

A blow, it is estimated that you can only rely on experience and feeling to predict the dodge, because the speed is too fast, the naked eye can not catch it at all, and the tip of the nameless sword also has a special type, that is, the air flow generated is very small, making the attack even more unpredictable.

The two of them already felt that they were foolproof, the sharpness of the nameless sword, and the super hardened skin of the S+-level zombie could be cut, and even if this huge mouse did not die on the spot, it was estimated that it would be seriously injured.

"Ding!"

The crisp sound of metal clashing broke the imagination of the two!

The giant rat flicked its front paws at random under the gaze of the two of them, and the tip of the nameless sword that shot at its head was shot away with an understatement!

The nameless sword tip that was blocked flew to the side under the reaction force, and Bai Qi also refocused on controlling it to continue attacking.

Unexpectedly, the huge mouse stood upright like lightning, opened its mouth and bit the tip of the nameless sword, no matter how Bai Qi controlled it, he couldn't break free.

According to the big mouse's thoughts, he was going to chew up this flying thing, but the tip of the nameless sword was not given for nothing, but was severely deformed by the bite......

The white heart is like a knife! Ever since he had obtained the tip of the Nameless Sword, he had never thought that it would be destroyed, and he couldn't believe what was happening in front of him!

In a daze, several mice had already pounced in front of him.

Lao Zhang quickly retreated, grabbed Bai Qi's collar at the same time, and ran away without saying a word!

The big rat is obviously not easy to deal with, there is already a sound of the propeller telling the spinning sound wave over there, knowing that Ye Qi has successfully started the gecko, so he rescued Bai Qi, and by the way, he slipped away!
