The fighting in the lobby of the office building continues.

Su Lingxuan and Poison Island Tsuneko met together, which greatly reduced the burden on Poison Island Tsuneko, giving her time to recover her strength, and with Poison Island Tsuneko's assistance, Su Lingxuan could also completely ignore the care of the zombies in other directions, and single-mindedly kill the zombies who rushed over by stepping on the corpses of their companions.

Staying by Su Lingxuan's side, Poison Island Tsuneko could see his movements clearly.

Su Lingxuan's swordsmanship is actually not very clever, and it is even clumsy, because he uses the swordsmanship used to come and go with only a few moves, and each move is a swordsmanship that is regarded as a basic action in various schools of swordsmanship in Japanese kendo.

But helplessly, Su Lingxuan's movements were too fast, his strength was too great, and his staying power was amazing, and the addition of the three made the power of swordsmanship skyrocket in an unscientific way. And his steps and body are very strange, hidden and strange, even if he follows his side, if he doesn't pay attention to his gaze, he will lose Su Lingxuan's figure, and when she locks on to the target again, there are already a different number of zombies that have fallen to the ground forever.

The more Poison Island looked at it, the more puzzled she became, "How can this kind of swordsmanship be so familiar......

In less than twenty minutes, the floor of the wide hall of the office building was covered with a thick pile of corpses, and if you roughly calculated, there were at least nearly two hundred corpses here!

Su Lingxuan's lethality is really amazing! The killing efficiency is also very high!

He himself has practiced the black school ninjutsu, and he has Shennong Liuli Gong in his body, which can be said to be full of physical strength and long pulses, and now he uses a sharp knife to kill zombies that are more than a step slower than ordinary people, and he shows the terrifying lethality, and shows the essence of the body knife technique created by the black school ninjutsu purely for killing and assassination.

Now he seems to be young and not strong, but in fact, he is already the most terrifying and top assassin or killer in the ordinary world!

"Whew...... Call...... Whew......"

Poison Island Tsuneko's breathing was very short, and the hands holding the handle of the war knife were trembling slightly, and he almost couldn't hold the battle knife.

In fact, the swordsmanship of the Poison Island family also has a matching breathing method, and in terms of quality, it is one of the best in this country, and even the ancient country in the East on the other side of the ocean is also very good. However, due to the constraints of the upper limit of force in this world, the function of the breathing method is very limited, mainly to calm the mind, better concentration, control physical strength, etc., and does not have the effect of practicing true qi, mental power and other levels of entry.

Poison Island Tsuneko is proficient in the swordsmanship and breathing method of the Poison Island family, and has also practiced both to an extremely high level, but she is still an 18-year-old girl, compared to Su Lingxuan, who uses the dual skills of Shennong Liuligong and Black School Ninjutsu to strengthen her body, after a fierce battle, it is normal to lose her strength.

However, this can also reflect the strength of her swordsmanship and the tenacity of her will, after all, ordinary people are far from being able to do this.

"It's not a good place to fight, so let's go up the stairs and fight as we retreat."

Su Lingxuan looked out of the hall, and saw the zombies with no end in sight.

They followed the singing sound of the broadcasting equipment to find this place from other places, staggering and dragging the mutilated body, you squeeze me, I squeeze you, one body next to each other, like a tide surging towards the hall, Su Lingxuan has even seen that the wall made of tempered glass has cracked a lot of cracks, it seems that it will not last long under the impact of zombies.

I don't know if it's because the virus that causes the human body or corpse to become a zombie has special side effects, the degree of decay of the zombies' bodies seems to be very fast, as far as Su Lingxuan's eyes can see, many zombies' bodies have shown signs of decay, and some zombies have been torn open by other zombies with their hands and teeth to tear open their chests and abdomen and leak their internal organs, and it can be seen that the organs inside have become jet black, rotten, and exude a strong smell.

"The zombies outside seem to be different from the zombies I saw before......"

Many of the zombies outside the hall were holding shovels, wrenches, wooden sticks, metal rods that had been removed from some equipment, and some were even waving their arms or thighs and other parts of the human body indiscriminately......

Compared to the zombies that Su Lingxuan had seen and killed before, these zombies seemed to have the consciousness of using rudimentary tools, which made Su Lingxuan's face sink involuntarily, and an ominous thought suddenly appeared in his heart.

"I'll clear the way."

Poison Island didn't dare to be reckless at this time, and took the initiative to retreat upstairs.

Su Lingxuan was covering her in the back, and at the same time, she was constantly slashing the zombies that rushed over.

Before using the broadcasting equipment to attract zombies to this side, Su Lingxuan and Poison Island had already carefully cleaned up the entire office building from the bottom up to make sure that there were no zombies alive on the building. Now start to retreat to the top, and don't be afraid of zombies suddenly ambushing the upper floors, just rest assured.

The figure of Poison Island Tsunako climbed up the stairs to the second floor, and when Su Lingxuan was about to leave, four sturdy zombies suddenly rushed over from the zombie group, their bodies were more intact than other zombies, and there were only a few insignificant tooth marks on their bodies, which were simply intact and did not look like zombies.

And their speed is faster than ordinary zombies, their movements are more agile, more fluid, not their eyes are blank, their skin is gray-blue, and the identity of the zombie is almost indistinguishable.

"Are these guys evolving?"

Su Lingxuan was also frightened at first, but soon he became happy, his muscles tensed slightly in excitement, and the corners of his mouth were slightly upturned.

The special zombies seem to be worth a little more martial arts!

It took a little more effort than killing ordinary zombies to kill four zombies, and Su Lingxuan really gained a martial arts value worth 80 points, that is to say, this kind of strong and agile zombie is worth 20 martial arts points, which is twice the value of ordinary zombies.

"This is really an evolution, isn't it?!"

Su Lingxuan muttered, seeing the zombies stumbling over on the corpses of their companions, flooding the entire hall like a tide, he hurriedly took a few steps back, jumped onto the platform between the two flights of stairs, and formed a line of defense through the narrow passage.

The fast-rushing zombies climbed the steps of the stairs, pushing each other upward, and Su Lingxuan took a step back, forming a condescending advantage.

"Whew! ————”

The war knife turned into black lightning again, and large black blood stains flew out from the zombies' wounds, and the three zombies at the head were cut off their heads to varying degrees, and the corpses fell softly on the stairs like dolls with broken threads, blocking the footsteps of the companions behind them.

The pungent stench rushed into his nose, and Su Lingxuan suppressed the suffocation and unhappiness in his chest, and made a war knife like a raging storm, cutting down all the zombies in an instant.

The zombies had no sense of pain or fear, nor did they have wisdom, they just followed their instincts and kept climbing the stairs and flocking to Su Lingxuan. The narrow passage prevented the possibility of zombies flocking to Su Lingxuan in large numbers, and Su Lingxuan was able to occupy favorable terrain and slash zombies more efficiently, but at the same time, it also limited Su Lingxuan's range of activities.

Fortunately, Su Lingxuan's original idea was to exchange space for time, and the strategy of destroying the enemy's living force was the main strategy, although people retreated step by step in the charge of zombies, but in fact, there were not many zombies who died under his knife, but because of the geographical advantage, it increased a lot.

Just take a step back, take a step back, take a step back, take a step back......

Su Lingxuan's retreat was not large, it was a step by step, and each step back effectively eliminated several zombies who were approaching, and at the same time, they also used their corpses to form a lot of obstacles to the zombies who climbed the stairs behind.

The harvester-like war knife kept waving in the stairwell, and the zombies fell one after another.

In just more than 20 steps, more than 50 zombies fell in a pool of black blood, and their corpses were stacked horizontally on the steps no more than two meters wide, densely crowded together, forming a very impactful picture on the eyeballs.
