The rats chased after each other, and the corridor was full of squeaky sounds, but Zhang Zhi had a plan, so he was naturally no longer afraid.

When he escaped to the 152nd floor, he was almost at the top of the skyscraper, and with a turn, he fled in the direction of the elevator.

If there is a heat sensor looking at the whole building from a distance at this time, you will definitely see a long winding dragon behind a person, from the top to about forty or fifty floors, and then down, there is no more.

Zhang Zhi ran to the elevator and saw that the elevator was closed, he didn't care, reached out and forcibly broke the elevator door and entered the elevator descending passage. The rats in the back followed closely through the fire ladder door, and when they reached the elevator, Zhang Zhi was already holding the elevator cable.

"Iron Palm!"

"Whoa!"

This is Zhang Zhi's operation skill, his palms turned into iron gray, grabbed the steel cable and fell, and his palms rubbed against the steel rope with a clattering sound.

The elevator door is wide open, and the rats behind it know that the door is the elevator passage of the entire building, which is more than 500 meters high, unless it can fly, any creature falling from here is basically the end of a lump of meatloaf.

Zhang Zhi controlled the speed, and the rats around him fell as it rained, and it even took a while before he heard the thud from below.

Some mice fell directly on Zhang Zhi and were also thrown out by him, but some second-level mutant mice still left a lot of wounds on his body, which made him feel a little itchy.

To Zhang Zhi's surprise, and he felt a pity, not a single silver and white mouse fell, not a single one.

After descending more than 100 meters, there were fewer mice falling down, probably because they found this situation, which made Zhang Zhi sigh secretly, in the long run, this rat nest is afraid that it will grow to an extremely terrifying realm, after all, this kind of social animal, once it has intelligence, it will be an extremely terrifying thing.

Zhang Zhi's descent speed was also extremely fast, but he occasionally tightened his hand to stabilize the descent speed. A few minutes later, he went down to the very bottom of the elevator shaft.

The bottom was pitch black, and Zhang Zhi climbed out of the elevator and found that it was also pitch black outside.

"I'll it! I forgot, the elevator generally leads directly to the basement, this building, I don't know how many basement floors are designed! ”

Fortunately, he had a lighter, and the lighter was lit to see, this is a parking lot, a lot of luxury cars, the pillar shows that this is the 13th floor underground.

"Fortunately, the basement of this building is only thirteen floors."

Skyscrapers generally underground piling will be very deep, 30-story buildings, underground piling is dozens of meters, this more than 100 floors, more terrifying, but piling is piling, building a basement is another thing.

Zhang Zhi casually smashed a car, took out the seat, found another gasoline car, took some gasoline, and used the seat as a torch and held it as lighting.

Every time he walked for a while, he had to freeze, concentrate his ears to listen to whether there was any movement, and he walked up seven floors, but he didn't find anything.

When I walked to the negative third floor, I finally heard a sound and smelled a strange fragrance.

"Isn't this a rat's nest? How can it be so fragrant? ”

Several times he suspected that he had crossed over to somewhere else, and that the rat nest must be smelly.

It wasn't until he saw a big rat in front of him that he was sure he had made a mistake.

Yes, there's a mouse in front of it, it's definitely a mouse, he's in the shape of a mouse, but with golden fur all over his body.

Zhang Zhi was sure that the aroma was emitted by this mouse.

"It smells so good!" This aroma made Zhang Zhi a little drowsy.

The golden mouse jumped from the roof of one car to the roof of another, only more than ten meters away from Zhang Zhi, as if smiling at him.

Zhang Zhi felt more and more fragrant.

"Hey, I'm so tired, let's rest for a while."

"That's not right! There's something wrong with this aroma! ”

Zhang Zhi woke up suddenly, although he had just run more than 100 flights of stairs and slid down from the 152nd floor, but with his current physical strength, these were trivial things, and it was impossible to be so tired that he needed to rest.

Realizing that there was a problem, Zhang Zhi's face immediately changed, and then he found that he had a tingling and refreshing feeling in his spirit.

"This, this turned out to be a virus above level five, a real mutant virus, this mutant rat has exceeded level five, and the plague has also mutated again!"

He's not like others, he's experienced.

After the animals evolve to five times, they will also have qualitative changes, and their innate ability can also mutate again to become a completely new ability, level 1 immunity, which has no effect at all.

This rat plague cannot be dealt with by itself.

"It's over, unless I upgrade my immunity to level 2 now, I'm dead!"

Zhang Zhi realized the seriousness of the problem, and under the turn of his mind, Zhang Zhi only found a way to live.

Kill each other, eat each other, this is not enough, you have to absorb enough energy from the other party, the physical energy exceeds 15 points, and the immunity evolves to level 2.

"Psychic Spike!"

His spiritual power formed a thorn of insubstantial energy, and there seemed to be an invisible spike that stabbed towards the golden mouse.

The golden mouse was extremely confident, of course he already thought that Zhang Zhi was already in the bag, and he was also a little excited, kicked on the roof of the car, and pounced towards Zhang Zhifei.

Suddenly, without warning, the golden rat was stunned in mid-air, and his whole body lost its balance and fell downward.

"Bang!"

The rat fell to the ground, mentally deranged, and became a real rat, without thinking.

But he had instincts, he felt the danger, immediately got up, grabbed the road and fled.

Zhang Zhi was also mentally weak at this time, but he didn't get to the point of trance, rolled on the spot, took out his saber, and stabbed the mouse in the back.

Bright red blood gushed out from the blood groove on the knife's body, Zhang Zhi pulled out the knife, stabbed it again, and stabbed it three times, and the mouse finally ran out of breath.

But Zhang Zhi's condition did not improve, but he felt that his nerves were becoming more and more numb, this kind of tingling and itching was not physically, but mentally, and he didn't even have a place to scratch, he wanted to put his hand into his head and scratch hard inside.

His eyes were blood-red at this point, but consciousness was still clear.

"One last stand!"

Zhang Zhi grabbed the golden retriever, looked at the wound on his neck, bit down, and sucked hard.

Streams of heat flowed into the abdomen, but it didn't stop the itch for the soul at all.

"Hisss hiss! Hiss! ”

Sucking continued, and the blood of the golden retriever also seemed to contain aroma, but Zhang Zhi couldn't care about it so much, either dead or alive, desperate.

After sucking for three minutes, the golden retriever rat was sucked into a small circle, but Zhang Zhi didn't stop, grabbed it directly, tore it suddenly, and pulled the whole skin of the mouse down.

The saber had already been curled, but it finally cut the mouse, Zhang Zhi did not hesitate for a moment, grabbed the heart and liver of the mouse, and stuffed it into his mouth if he could eat it.

As for the rat meat, of course, he would not let it go, and the saber was quickly slashed, removing the bones, and without even cutting it into pieces, he chewed it whole.

At the end of the meal, his consciousness began to blur, as if the whole world was full of aroma, and the numbness and itchiness of his spirit had gradually become numb.

"I can't sleep!"

"Ahh

A knife went down, this time not on the mouse, but on his own arm.

The astonishing tingling pain made him sober again, but where was the digestion so fast, he just watched his fitness stats slowly grow.

At this time, his body, stomach digestion is already extremely strong, but according to his estimates, it is only half an hour, and if there is not enough time, everything will be late.

But at least you have to withstand it for half an hour.

It has only been ten minutes since he jumped down and smelled the aroma to eat the golden retriever, but Zhang Zhi already needs to use his own way to stay awake.

Soon, however, he saw hope.

Opening the stat bar again, he saw that his physical strength had crossed the threshold of 13.

The torches made of the stools had already burned, and Zhang Zhi smashed a car again, lit new torches, and staggered forward.

Five minutes later, his fitness had soared to 14 points.

The second floor was also empty, but he heard a squeak from upstairs, and the rats were all gathered on the first floor.

Ten minutes later, Zhang Zhi's physical fitness reached 15 o'clock, a joy from his soul, which made him suddenly become extremely awake.

Looking at the words "Please choose whether to promote this skill" displayed behind the level 1 immunity in the skill bar, Zhang Zhi finally breathed a sigh of relief.

Without hesitation, he chose yes, the system will not prompt again, this is his only chance.
