There are a total of eighteen floors in the Aegis Building, the higher you go, the stronger the monsters you encounter, those genetic zombies on the first floor should be the failure of the original experiment, and on the thirteenth floor, the genetic zombies here have stronger physical fitness and more advanced equipment, although they are also level 20, but they give Song Jian the feeling that they are like two monsters of different levels.

Standing at the side door of the stairs on the thirteenth floor, Song Jian cautiously probed to see if there were any monsters waiting outside the side door. Fortunately, there were only two level 20 ordinary genetic zombies outside the door.

Both of these genetic zombies were humanoid, with glazed eyes, and they staggered from one end of the hallway to the other. Neither of these genetic zombies wore any protective clothing or weapons, and they looked no different from ordinary mutant zombies.

It's as if the robot has set its course, and they don't even change their walking posture, and they just walk back and forth in the hallway.

According to the mission map, the "polymer analyzer" is in the laboratory diagonally opposite the side door, and if you want to enter it, you will definitely alarm these two monsters, and if you let these two monsters enter the laboratory, the "polymer analyzer" may be damaged during the battle......

Thinking of this, Song Jian took a deep breath, clenched the Red Fire Heart Ape Sword in his hand, and began to wait patiently for the two mutated zombies to walk in.

When the two mutant zombies approached, Song Jian directly cast the "Spirit Control Sword Technique", and the transparent spirit sword slashed towards the mutated zombie closest to him.

In an instant, a terrible roar echoed throughout the corridor on the thirteenth floor, and the mutated zombie who was hit by the spiritual sword rolled on the ground with its head in both hands, and its body began to change violently, the muscles bulged one by one, and the body also grew black dense hair, and the clothes were torn by the bulging muscles, and the pale face, which was originally bloodless, also began to twist and deform, and the bones made a "click" friction sound, and in a blink of an eye, it became a strong werewolf with a height of more than two meters.

The other mutated zombie originally looked sluggish, but the moment he saw Song Jian, his two eyes suddenly became smart, and he showed a weird smile towards Song Jian, two fangs poked out of his upper lip, and his scarlet eyes flashed with bloodthirsty light.

Song Jian felt that it was dark in front of him, and this mutated zombie moved extremely fast, and he actually pounced directly in front of Song Jian, holding his head, opening his big mouth, and biting towards the major artery on his neck.

Finger of the sword!

A silver sword qi pierced through the mutated zombie's chest and stabbed straight out.

Boom!

The body of the mutant zombie in front of him suddenly exploded, turning into countless palm-sized bats, fluttering towards the back.

Song Jian was stunned for a moment, feeling that the scene in front of him seemed to have been seen somewhere, and it was very familiar.

Not far away, the bats regrouped and turned into a middle-aged European man with blond hair and a black dress.

His face was very pale, but his lips were unusually ruddy, he stared at Song Jian, elegantly stroked his right hand on his chest and saluted slightly: "The sweet taste of blood, I haven't tasted such powerful blood for decades, thank you, strange human, for saving me from that state of chaos like the walking dead, and in return, I can drain your blood all over your body and leave you a complete corpse!" ”

After speaking, this genetic zombie showed a greedy and mysterious smile, and its figure rushed towards Song Jian like lightning, and in an instant, it left a deep scratch on Song Jian's chest, if it wasn't for Song Jian taking two steps back in time and forcing it back with the Red Fire Heart Ape Sword in his hand, this time, maybe he could dig out Song Jian's heart.

Song Jian glanced at the werewolf who was still rolling on the ground, the pain caused by the spiritual sword to it, I don't know how long it will take to recover, this werewolf gene zombie is obviously a warrior with strength attributes, and the genetic warrior in front of him who seems to be a vampire is mainly agile, once the two of them join forces to attack Song Jian, I am afraid that Song Jian can only flee in the wilderness, and if he is not careful, he may lose his life here.

Speed Sword!

Song Jian's eyes couldn't keep up with the speed of this genetic zombie at all, so he could only rely on his perception and use the attack speed increased by the speed sword to fight against it.

Vampire zombies come and go like the wind, and every attack can add a scar to Song Jianjian's body, licking the blood brought out of his nails, and the vampire zombie has a sickly intoxicated look on his face.

In just a few seconds, Song Jian was left with more than a dozen wounds, but fortunately, the opponent's attack speed was fast, but the damage caused each time was not high, only twenty or thirty points, counting Song Jian's qi and blood value recovery speed, even if he carried it to let the other party attack, it would take dozens of minutes to empty Song Jian's qi and blood value.

However, at this time, the werewolf zombie seemed to have recovered, and although the eyes looking at Song Jian were a little afraid, they were more angry and tyrannical.

Swish~

It was another wind-like attack, and when Song Jian felt a stinging pain in his shoulder, the vampire zombie had already quickly left it a meter or two away.

Sword wire!

Three thin silver lines appeared next to Song Jian out of thin air, and at this moment, the werewolf zombie roared and rushed towards Song Jian, its two front paws popping out three sharp blades, flashing with a metallic cold light.

Bang Bang Bang ~

The three sword wires that originally wanted to attack the vampire zombie detected the werewolf zombie approaching, and immediately set fire to it.

One of the three sword wires was drawn into the opponent's face, and the other two stabbed into the opponent's shoulder, almost slashing off its right shoulder.

Just when Song Jian breathed a sigh of relief, the werewolf zombie glanced at his right arm, slightly aligned the bone with his left arm, and then twisted it, and in two or three seconds, the right arm was unharmed and reconnected together, and there was not even a trace of scar visible from the appearance.

Song Jian gasped, the recovery speed of this qi and blood value was even more terrifying than his, if he wanted to kill this werewolf zombie, it seemed that he really had to dismantle the other party into eight pieces, and then burn it to ashes with fire.

Fortunately, the two genetic zombies seem to be attacking together, but there is no tacit understanding and cooperation at all, and the werewolf zombies often rush forward regardless of it, blocking the attack route of the vampire zombies several times, making the vampire zombies look at its neck, revealing a malicious look.

Of course, these two genetic zombies are obviously much more rational than the failed test subjects in the following layers, and they finally did not stage such a pleasant scene as "infighting" in front of Song Jian.

Song Jian also gave up his defense, wielding the Red Fire Heart Ape Sword, using the fighting style of exchanging injuries for injuries and exchanging lives for lives, and carrying it hard with the other party.

Soul Control Swordsmanship!

When the cooldown time ended, another transparent spiritual sword condensed above Song Jian's head, and the werewolf zombie seemed to feel something, and the blade that had already grabbed Song Jian's shoulder also retreated violently, taking five or six steps back in a row, with a vigilant look on his face.

Sou~

The vampire zombie took the opportunity to pounce on Song Jian, the fangs in his mouth were aimed at Song Jian's neck, this kind of strong blood full of power, to it, it was like a DU product full of irresistible temptation;
