While Ye Feng was rushing towards the building where Yiyalan was, Yiyalan was fighting fiercely with the corpse tide.

In just five minutes, Yiyalan retreated to the tenth floor. She could not resist the swarm of corpses, and they all retreated while fighting.

Fortunately, Ye Feng left her enough weapons and equipment. Yiyalan pulled it directly from her waist, pulled out a fire bomb, and then threw the corpse swarm towards the corridor.

boom!

The explosion of the incendiary bomb instantly turned the place in the corridor into a sea of ​​fire.

However, this scene did not make Yiyalan feel any joy. The Rifter rifle in her hand swept towards the sea of ​​fire while quickly retreating.

Sure enough, in just a moment, even though the zombies were burning with flames, they rushed towards her wildly.

However, there was no panic in Yiyalan's eyes. She stepped back and kicked the oil tank next to the stairs, allowing diesel to fill the corridor.

When the zombies whose bodies were burning with flames rushed over, the flames on their bodies instantly ignited the diesel. Then this time, it was not a small area that caught fire, but a raging fire was instantly ignited in the entire corridor.

Seeing this scene, Yiyalan's face showed a smile. Then she took out the two grenades hanging around her waist and threw them in the back. After two roars, the entire sea of ​​fire became violent.

Yiyalan took advantage of the situation and swept all the bullets of the Tearman Rifle in her hand, then rushed to a corner, took out the grenades and magazines that had been prepared inside, and quickly replaced them.

These things are all the preparations made by Yiyalan on each floor when Ye Feng sneaked into the research institute. Obviously, these preparations came in handy.

Otherwise, Ye Feng would not be able to bring all the ammunition with Yiyalan. She would not have the evolution box like Ye Feng, which is a magical tool that can store things.

Yiyalan looked at the corridor again, and estimated that the zombies would rush out soon, so she walked towards the stairs.

But at this moment, from the corner of her eyes, she suddenly saw a black shadow flashing on the sightseeing glass at the stairs, and then the window broke instantly. A hunter jumped and rushed towards her.

This scene immediately shocked Yiyalan, because she had never encountered such a thing before.

Yiyalan's reaction was also extremely rapid. Just as the moment she saw the black shadow, her lacerator rifle quickly aimed at it and then pulled the trigger.

Although her marksmanship is not very accurate, her shots will definitely force the predator to dodge in a hurry, and this will win the most critical time.

When the predator finally rushed to the front, a space shield had already condensed in Yiyalan's hand.

laugh!

When Iyalan condensed the Shield of Space, the result of this battle is conceivable. The sharp claws used by the predator were instantly shattered by the Shield of Space, and its head was also shattered together.

In just a moment, this predator who was good at sneak attack died under the shield of space.

However, seeing the predator die, Iyalan's face did not feel any relief, but instead showed a solemn look.

She quickly walked a few steps and looked outside at the window. Her face suddenly became ugly, because as she expected, this was not just an isolated case. Below the building, there were many predators and dead claws, relying on their sharp claws, constantly climbing up.

And Yiyalan could even see that in the center of the corpse group below, there were two virus-wearing people in black robes, making strange shouts.

No need to think that the reason why these mutated zombies came in from outside must be the result of the command of these viruses.

This scene made Yiyalan's silver teeth clench. She took out the lacerator rifle and shot wildly at the mutant zombies below, killing the two predators. The dense footsteps were heard behind her.

Obviously, the corpse group had crossed the fire and chased after it.

This forced Yiyalan to give up and continue to shoot the mutant zombies with his gun and run away again.

However, the virus's move was too ruthless. The mutant zombies approaching outside posed a great threat to Iyalan.

When Iyalan arrived on the 11th floor, there were not only one predators who jumped in through the window to block the predators, but two.

And when we reached the 12th floor, even the dead claws chased after them.

When it arrived at the 15th floor, Yiyalan couldn't even think about resisting the corpse chasing behind him. Almost all her attention was to be placed on the harassment of these mutated zombies.

If she had not arranged the back path in advance and placed a large number of weapons along the way to squander her, she would have been caught up by the huge group of corpses behind her and torn to pieces by the harassment of these mutant zombies.

But even so, her situation is already in danger. If it weren't for the space shield to resolve the crisis again and again, she would have died long ago.

However, the space shield consumed too much. When Yiyalan arrived at the 20th floor, her energy had already consumed nearly 80% of it.

At this time, there were nearly 20 zombie animals besieging her, which made Yiyalan feel like she was unable to move forward.

If this is the case, it is a question whether you can reach the 30th floor.

When Iyalan turned a corner and picked up 20 grenades and incendiary bombs placed in advance, as well as some supply bullets, and was about to go towards the stairs. However, she was shocked to see that in the direction of the stairs, these five dead claws slowly descended from above.

It is obvious that the road ahead has been completely blocked, and it is impossible for her to pass through the interception of five dead claws.

At this time, Yiyalan's face was already despair. She looked at her watch and saw that it had been eight minutes since the missile bombing. Ye Feng should have arrived, and then a trace of hope appeared in her heart.

She gritted her teeth and took the supply resources she had just obtained and headed towards the nearest room.

In the corridor, she can be said to be attacked from both sides. In this case, it is almost impossible to survive this last period of time.

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

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