Yun Ye didn't know if the thing that attacked him could see himself in the shadow hiding state, but he guessed that that thing should be the same as himself, and he couldn't see what the other party looked like and where he was.

If it can see where it is, it will not attack when it is making a sound when it is going up the stairs, but will wait until it has completely ascended to the landing between the second and negative floors.

Thinking from another perspective, if he was in the position of a mutant, Yun Ye was sure that he would definitely wait for the mutant to reach the platform before starting to attack.

The staircase landing, not up or down, is a flight away from both doors, and is the most suitable location for attacking, and when you first go up the stairs, you are the most vigilant, and once you reach the staircase, it means that this stairwell is halfway through.

Halfway through the walk, there is no danger, presumably there will be some relaxation of vigilance, and that is the best time to start.

This location, not only is it quite far away from the two gates, once it is attacked, it will not be able to run to the mouth of the escape passage in the first place, and it will not be illuminated by the light, it is still pitch black, and the prey still cannot see the hunter hidden in the dark.

And judging by the proficiency of the mutant who attacked him, it must not be the first time he has done this kind of thing, so there will definitely not be a situation where he can't hold his breath.

Coupled with the fact that he had been hiding here for such a long time, the mutant did not launch a second attack. All of this takes it all together, and it shows that the mutant who attacked him is also like himself, and he can't find himself in the stairwell where he can't see his fingers.

The reason why I was attacked by it should be the crisp sound when I walked up the stairs.

As soon as he thought of this, Yun Ye was very distressed, he had no professional training, and it was impossible for him to be silent and windless.

That's why every time he starts a gallop or a full speed, he makes such a big noise.

But these are all off-topic, and the most important thing now is how to get out of this stairwell unharmed.

Although the mutant can't see, it doesn't mean he can't hear or smell.

When he moves, he will inevitably make a sound, which indirectly reminds the mutant of his position, and the blood coming out of the wound on his chest has become more and more, and the smell of blood has become stronger and stronger, and the mutant can also judge his position by smelling the intensity of the smell of blood.

So, we have to find a way to break this situation.

Yun Ye held his breath, his brain spinning rapidly.

I fell with a wall on my back, and I flew backwards, which means I'm back on the landing on the second floor.

Yun Ye turned around, but he didn't find the fire door, after he entered the door just now, the fire door closed automatically, and in the darkness where he couldn't see his fingers, it was so difficult to find a fire door.

Yun Ye thought about it, it seemed that he had to create some light before he could find the location of the fire door, but once the fire was created, the mutant would definitely find himself.

What if there is something that can temporarily attract its mind?

Grenade!

For the first time, an infantry grenade popped up in Yun Ye's mind.

According to the previous observations, the killing radius of the infantry grenade should be about five meters, and I went up 9 steps just now, and I didn't touch the corner on the guardrail, which means that this staircase has at least ten steps.

The cross-sectional width of a step is longer than the sole of one's foot, so the length from this stairwell to the middle landing should be at least two meters four or five, if you count the width of the stair landing.

Then the depth of this stairwell should be three or five to four meters.

If the force and direction are right, and the grenade can be thrown into the corner, it should be feasible.

"Xiao Yunzi, you have to think about it, once there is a little mistake, you will be gone." The gray old man, who sensed Yun Ye's thoughts, couldn't help but admonish.

Yun Ye nodded with a solemn face, and replied silently in his heart, "It's okay, I can only gamble, if I don't get killed by the mutant here, I will hang up because of excessive blood loss." ”

More and more blood flowed out of the wound on his chest, and the smell of blood was getting stronger and stronger, and Yun Ye even heard a slight sound from the ceiling, indicating that the mutant had smelled blood and was groping in his direction.

The hand sank, and two grenades suddenly appeared in the originally empty left hand.

Softly unplugging the insurance, Yun Ye said silently in his heart.

Grenade, grenade, you must recognize who your master is, and you must not hurt me by mistake.

Finding the right direction and grasping the strength, Yun Ye gently threw a grenade out.

Big brother, big brother, don't you want to bounce back!

Holding his breath, Yun Ye waited quietly, obviously it was only a few seconds before the grenade exploded, but now it felt extraordinarily long, Yun Ye was afraid that the strength or angle would not be mastered well, and the grenade thrown out bounced back.

At that point, the fun will be really big.

Fortunately, the grenade that was given high hopes by Yun Ye successfully played his role, with a loud bang, a brilliant spark suddenly bloomed on the platform leading to the negative floor, although it was not successfully thrown in the corner of the platform, fortunately, the place where it was thrown was also relatively deep, and it did not accidentally hurt Yun Ye.

It's just that the air wave generated by the explosion almost lifted Yun Ye, who was half lying on the ground, out of the air.

"Sigh......!" There was a low roar from the ceiling, and a dark shadow flashed and swooped towards the platform.

It's done!

While the fire was not extinguished, Yun Ye rushed out, rushed to the fire door with a brisk step, opened the fire door, and quickly rushed out.

All these movements were like flowing water, without the slightest pause in between, and when the mutant reacted, Yun Ye had already opened the fire door, and it flew directly over with a roar, and its thick and powerful forelimbs grabbed Yun Ye's back.

However, this time, the mutant did not keep Yun Ye, but it blocked the fire door that was about to close, and its thick and powerful forelimbs blocked between the fire door and the door frame.

With the exertion of its forelimbs, the fire door was easily opened by it, but it saw that Yun Ye did not run away immediately after rushing out of the stairwell, but half-threw himself on the ground with his head in his hands.

The mutant was puzzled, its limited intelligence didn't know why Yun Ye did this, but it didn't care about it, and the blood food sent to the door was not eating.

No sooner had it stepped out of its front foot than a thud exploded under its belly.

A loud bang, a spark, a scream. The mutant's not very large body was directly blown off.

It turned out that the second grenade thrown by Yun Ye exploded, he had only thrown out one grenade before, and the second one had been held in his hand until he ran away.

Yun Ye knew that the mutant would definitely find itself running away, and with its rapid speed, it would definitely rush out, so Yun Ye left a gift for it at the door.

Yun Ye naturally heard a loud noise behind him, and after the aftermath of the grenade explosion, Yun Ye slowly raised his head and got up, but the truth disappointed him.

The mutant still stood there, wrapped in a layer of silver-gray leather, and didn't look badly injured, except for its front paws, which had a bloody scar that had been blown apart.

The mutant couldn't tell what it was before, it had a slender body, a round and thick head like a bucket, and at the front of it was a round mouth full of fine and sharp teeth, and the scarlet tongue in the mouth kept swallowing, like a sinister poisonous snake waiting for an opportunity.

Behind the bucket head, there is a pair of thick and powerful forelimbs, the forelimbs are extremely thick, three points thicker than Zhi Yunye's waist, and the finger claws are as sharp as knives, just standing on the reinforced concrete ground will leave traces half a finger deep.

The tail is thick and swings in the air, this tail is not like the tail-bearing mutants that Yun Ye has encountered before, this tail is not only extremely thick, but also covered with sharp thorns on the upper and lower sides, which looks like a chainsaw.

Yun Ye estimated that the scars on his chest should have been caused by those barbs.

"Mutant, level 9."

Level 9! With a groan, Yun Ye's face changed suddenly, the level 9 mutant said that he could not match anything, which was simply an invincible opponent for the current Yun Ye.

Without the slightest hesitation, Yun Ye pulled out his legs and ran.

The unknown mutant did not allow the imminent prey to escape, and its thick forelimbs kept exchanging and crawling, shooting up a cloud of rubble.

Maba, are you still running so fast even when you're injured?!

Yun Ye, who was on the way to escape, listened to the sound of getting closer and closer behind him, and he wanted to cry without tears.

Now he can't win a fight, and he can't run away.

No, we have to get rid of it.

Soon, Yun Ye had already run out of the negative second layer and came to the negative first layer, he had to find a way to get rid of the mutants behind him, otherwise he would definitely die!

Yun Ye glanced at the many cars parked in the parking lot, and thought about it for a while.

Cars, I'm sorry!

Turning on the swiftness, grenades that appeared out of thin air were thrown continuously.

After a series of actions, Yun Ye basically threw out all the remaining grenades.

Moreover, the effect is also very obvious.

"Boom Boom Boom Boom ......"

The continuous roar was deafening and incessant, and the entire parking lot seemed to tremble under the continuous explosion, and dust was constantly falling from the surrounding pillars and ceilings.

The mutant's huge body was obviously stagnant, and a grenade could injure his forelimbs, and now it exploded so violently and continuously, even if it didn't dare to chase hard.

The flames rose, and the entire parking lot below seemed to turn into a sea of fierce fire, with vehicles exploding and smoke billowing out.

"Ahem, ahem, ahem......"

Yun Ye stood in front of the sea of fire, coughing violently, and even he was a little unable to open his eyes because of the billowing smoke.

Yun Ye, who couldn't stand the high temperature and billowing smoke, decided that it would be better to leave, originally he was still thinking about whether it was possible to lure the level 9 mutant into the sea of fire to die, but the mutant was obviously not low in intelligence, and when faced with the burning sea of fire, he chose to retreat temporarily.

Looking at the mutant's retreating figure, Yun Ye fiercely raised his middle finger to express his inner dissatisfaction.
