Su Lingxuan and Poison Island retreated while fighting, and the mutilated corpses were covered along the way.

The strong fishy stench filled almost all the stairs, and the smell of decomposing corpses was so strong that it could be smelled far away from the office building.

On the way up, the two also found time to rest. Using the room on each floor of the office space, the number of zombies was greatly dispersed, and the two of them hid in a secluded place to rest, and when their strength was almost recovered, they went out again to hunt the zombies trapped in the room.

Of course, this is also related to the rapid growth of the two in the fierce killing.

In the midst of the fierce battle, Poison Island had already destroyed the broadcasting equipment according to Su Lingxuan's instructions, and no longer attracted more zombies to gather here, but the zombies who were attracted by the commotion of their companions were still rushing here in an endless stream.

The zombies were completely irrational, no matter how Su Lingxuan and Poison Island killed them accurately and efficiently, the zombies behind them were still surrounded like a tide, with their teeth and fingertips, or the utensils they didn't know where to get their hands, and kept greeting the two of them.

Su Lingxuan has a strengthened clothing protection on her body, which can effectively resist the attacks of the zombies, but the poisonous island is not good, she does not have a strengthened clothing on her body, and the clothes she wears are only the school uniform of the light and cool Vine Art Garden, and the lower body is just a long skirt that is over the knee, such a dress usually looks very pleasing to the eye, but in the battle, especially the virus carried by the zombies is also highly contagious, it presents great inconvenience and disadvantages.

When more and more zombies surround him, and there are still many zombies holding things in their hands, the combat power of Poison Island Tsunako is rapidly declining, and more and more energy needs to be used for defense and dodging.

Seeing that the situation was unfavorable, Su Lingxuan suddenly bent down and squatted, and with one hand of his left hand, he supported the ground with one hand, and used a whirlwind leg.

"Bang...... Bang...... Bang......"

His figure spun rapidly like a spinning top, and in a burst of body collisions and fractures, he forcibly cleared out a blank area with a radius of nearly two meters.

Through the reinforcement of the reinforcement suit, his leg strength is ten times that of ordinary humans, and the zombies around him have long been overwhelmed by the erosion of the virus on the body, and the bones cannot help but force high-intensity operation, and now he swept out this move, and immediately swept off the legs of the zombies around him, and smashed it heavily on the bodies of his companions.

However, the zombies didn't feel pain, Su Lingxuan's whirlwind legs swept off the legs of the zombies around him, and smashed on the other lost bodies, messing up the formation of the zombies' attack, but the zombies who fell to the ground simply crawled to grab Su Lingxuan's legs, and the zombies in the rear couldn't help but squeeze forward, stepping on the bodies of their companions and continuing to rush this way, Su Lingxuan only felt a lot of pressure for a while, and the upper and lower branches were weak.

However, fortunately, the whirlwind leg just now swept out a clearing, and Su Lingxuan used this rare space to quickly swing his knife and kill another batch of zombies around him, using their corpses to slightly block the impact of the zombies behind.

"Go to the top of the building, you go first, I'll break off behind."

Su Lingxuan shouted at Poison Island Tsuiko, who was slightly stunned, but he still reacted in an instant, turned around and ran up the last stairs, opened the door and rushed to the roof.

Then, Su Lingxuan killed a few more zombies who rushed quickly, and reached out to dodge a baseball bat that was held by the zombies. Before the zombies gathered around him again, he jumped over a dozen steps, and after locking the door to the roof, he reflexively buckled the door from the outside, and pinned a pair of handles on the door with a baseball bat.

At the moment when he finished all these actions, Su Lingxuan only felt that his spirit was in a trance, his whole body was empty, he couldn't exert a little strength, the vision in front of him shook for a while, and the movement of the zombies behind the door became smaller and smaller, as if the two sides had distanced themselves, and they were still moving away little by little.

"It's a physical overdraft!"

Su Lingxuan, who knows a lot of medical knowledge, instantly figured out the situation he is experiencing now, this is a symptom of people's physical fitness and spirit after strenuous exercise, and it is generally a symptom that the intensity of exercise is close to the limit state of the body, and when ordinary people show this symptom, it is often accompanied by a brief coma, and because his physical strength and spirit exceed the limits of ordinary people, the symptoms are slightly better than ordinary people.

After all, Su Lingxuan is a human, not a robot, although he has studied Shennong Liuligong and Black School Ninjutsu, but the time he has been in contact is too short, and he has not yet practiced his mental power and true qi, and he can't maintain superhuman durability, just fought with the zombies all the way in the office building, and the pressure on each zombie on him is not great, but the number of the other party is too amazing, and when he sees one batch, another batch is replenished, which brings huge consumption and load to his physical strength and spirit.

During the battle, he did not notice the physical and mental exhaustion because of his nervous spirit and high fighting spirit, but now he came to the temporary safe place on the top of the building, and his mental will was relaxed, and the fatigue of his body and spirit was immediately fed back to him, making him sleepy.

"I'm in trouble!"

Su Lingxuan bit the tip of his tongue lightly, using the pain to keep his consciousness awake, the current situation is definitely very bad, the door in front of him can't last too long in the impact of the zombies, if he can't recover his strength before the zombies break out of the door and leave with the poison island, then what awaits them is the end of being reduced to zombie rations!

"But it's okay, I still have a backhand."

His brows furrowed, and Su Lingxuan's expression returned to calm in the next moment.

"Now hurry up and rest for a while, and then we'll leave and find someone else."

“…… Are you really okay? A trace of worry flashed in Poison Island's eyes, she had seen Su Lingxuan's body shake and almost fall to the ground just now, she knew very well that it was a symptom of body overdraft.

Su Lingxuan waved his hand nonchalantly, "Don't worry about me, everything is not out of my control." ”

“…… I hope so. Poison Island Yanzi tightened his palm holding the handle of the battle knife, looked at Su Lingxuan's back and stopped talking, but a touch of determination quietly flashed in his eyes.

Ignoring Poison Island's actions, Su Lingxuan walked to the guardrail farthest from the gate and sat down with his back to her.

"Bang...... Bang...... Bang...... Bang! ”

The impact of the zombies one after another finally broke through the gate, and the figure of the zombies flooded most of the space on the roof of the building in an instant, and rushed towards the two people on the opposite side with a fierce momentum, and the poison island man standing behind Su Lingxuan bore the brunt.

"Poof!"

At this time, Su Lingxuan hadn't stood up yet, it should be that his physical strength and spirit hadn't recovered yet, Poison Island Tsuiko's eyes were sharp, and he didn't bother, but he quickly stood behind Su Lingxuan without thinking about it, and the battle knife slashed forward quickly, splitting the zombie that rushed in front in half from head to toe.

Su Lingxuan's physical strength has not yet recovered, and she must support it.

This is not only to repay her for saving me several times in the battle just now, but also for my own safety! Without her help, I wouldn't have survived alone!

With this resolute awareness, Poison Island Tsuneko resolutely began the battle.

However, the course of events does not shift by human will!

Although her swordsmanship is superb and she has extremely sharp swords, the number of zombies is too much, and her physical strength is only stronger than that of ordinary girls.

"Oops!"

When he was taking care of himself, Poison Island Tsunako suddenly noticed that another zombie had bypassed him, and his snow-white teeth with scarlet flesh were quickly approaching Su Lingxuan's face.

"Danger!"

The knife in her hand was slashing into the body of a zombie, where could she pull it out in an instant, seeing that Su Lingxuan was about to be bitten, the scene of being rescued several times suddenly appeared in her mind, and at the critical moment, she didn't think much about it, she threw her hand to push the zombie's jaw, as for whether she would be bitten, she didn't think about it at all.

Hearing the noise next to him, the zombie's mouth was like a shark smelling blood, its head lowered, and its teeth bit down on the slender jade hand that was stretched out.

"That's a tie!"

In the last thoughts, Poison Island Tsuneko thought so.
