When Ye Feng hurried towards the building where Yi Yalan was, Yi Yalan was fighting fiercely with the corpse tide.

In just five minutes, Yi Yalan retreated to the tenth floor, and she couldn't resist the swarming corpses at all, and they all retreated while fighting.

Fortunately, Ye Feng left her with enough weapons and equipment, and Yi Yalan pulled an incendiary bomb directly from her waist, and then threw it towards the swarming corpses in the direction of the corridor.

Rumble!

The incendiary bomb exploded, instantly turning the place in the corridor into a sea of fire.

However, this scene did not make Iyalan have any joy, and the Ripper rifle in her hand quickly retreated as she swept towards the sea of fire.

Sure enough, in just a moment, even though the zombies were burning with flames all over their bodies, they also frantically rushed in her direction.

However, there was no panic in Iyalan's eyes, and as she retreated, she kicked down the oil tank next to the stairs, causing diesel fuel to fill the entire hallway.

When those zombies whose whole bodies were burned by flames rushed over, the flames on their bodies instantly ignited these diesel fuels, and then this time, it was not a small place that caught fire, but the entire corridor instantly ignited a raging fire.

Seeing this scene, a smile appeared on Iyalan's face, and then she took out the two grenades that hung on her waist and threw them backwards, and after two roars, the entire sea of fire also became furious.

Iyalan swept away all the bullets from the Ripper rifle in his hand, and then rushed to a corner, took out the grenades and magazines that had been prepared inside, and quickly replaced them.

These things were all the preparations made by Ye Feng at each level when Ye Feng infiltrated the research institute, and it was obvious that these preparations came in handy.

Otherwise, Ye Feng left so much ammunition, and it was impossible for Yi Yalan to bring it all, she didn't have an artifact like Ye Feng, which could store things.

Iyalan glanced at the corridor again, estimating that it would not be long before the zombies rushed out, so he walked towards the stairs.

But at this moment, out of the corner of her eye, she suddenly saw a black shadow flashing on the sightseeing glass at the staircase, and then the window burst instantly, and a predator jumped and pounced on her.

This scene suddenly shocked Iyalan's heart, because such a thing had never been encountered before.

Iyalan's reaction was also extremely fast, and the moment she saw the black shadow, her Ripper rifle quickly aimed at it, and then pulled the trigger.

Her marksmanship was not very accurate, but a single strafing shot could definitely force the predator to dodge in a hurry, and this bought the most critical time.

When the predator finally rushed closer, Iyalan's hand had already condensed a spatial shield.

Laugh at!

In the case of Iyalan's condensation of the spatial shield, then the result of this battle can be imagined, the predator's claws used to attack were instantly shattered by the spatial shield, and its head was crushed along with it.

In just an instant, this sneak predator died under the shield of space.

However, seeing the death of the predator, Iyalan's face did not show any relief, but showed a solemn expression.

She hurriedly walked a few steps, came to the window and looked out, and her face suddenly became ugly, because as she expected, this was not the only case, and below this building, there were many predators and death claws, relying on their sharp claws, constantly climbing upward.

And Iyalan could see that in the center of the corpse group below, there were two virus people in black robes, who were letting out strange screams from their mouths.

Don't think about it, the reason why these mutant zombies came in from the outside must be the result of the command of these virus people.

This scene made Iyalan's silver teeth clench, and she took out her Ripper rifle and fired wildly at the mutant zombies below, killing the two predators, and a dense footstep could be heard behind her.

It was clear that the corpses had already crossed the flames and chased after them.

This forced Iyalan to give up, continue to shoot mutant zombies with guns, and run away again.

It's just that the trick of those virus people is too ruthless, and these mutated zombies approaching outside have posed a great threat to Iyalan.

By the time Iyalan reached the 11th floor, there were not just one, but two predators jumping in through the window.

And when they reached the 12th floor, even the Dead Claws chased after them.

And when he reached the 15th layer, Yi Yalan didn't even have much thought to resist the group of corpses chasing behind, and almost all of his attention was on the attacks of these mutated zombies.

If she hadn't arranged the back road in advance and placed a large number of weapons along the way for her to squander, I am afraid that under the harassment of these mutant zombies, she would have been chased by the huge group of corpses behind and torn to pieces.

But even so, her situation was already precarious, and if it weren't for the spatial shield to resolve the crisis again and again, she would have died a long time ago.

However, the consumption of the space shield was too great, and by the time Iyalan came to the 20th layer, the energy in her body had already been consumed by nearly eighty percent.

At this time, the zombie animals besieging her were close to 20, which made Iyalan feel that it was difficult to move an inch.

If you go under this scenario, it will be a question of whether you can reach the 30th floor.

When Iyalan turned a corner, picked up 20 grenades and incendiary grenades that had been placed in advance, as well as some supply bullets, and was about to head in the direction of the staircase. She was shocked to see that in the direction of the stairs, there were these five dead claws slowly descending from above.

Obviously, the road ahead has been completely blocked, and in the face of the interception of the five dead claws, it is impossible for her to pass at all.

At this time, Yi Yalan's face already had a look of despair, she looked at her watch, and saw that eight minutes had passed since the missile bombardment, and Ye Feng should be about to arrive, so there was a glimmer of hope in her heart.

Gritting her teeth, she took the supplies she had just acquired and headed for the nearest room.

Here in the corridor, she can be said to be under attack, and in such a situation, it is almost impossible to survive the last period of time.

Her only hope was to enter the room, find a way to stick in a corner, and delay as much as possible until Ye Feng came to the rescue.

Of course, for this, even Iyalan himself did not have much hope.

Because according to the plan, Ye Feng didn't know that she was trapped on the 20th floor, even if she was found later, it was so difficult to rescue her surrounded by this group of corpses.
