Wen Qianfang shouted and turned around and ran, "Wow, oh, wow" his legs walked fast, panicked, stepped on the air, lost his balance, and rolled down.

Nie Yuqian's mind was dazed, and when she saw the monster walking towards her violently, she quickly woke up and fled with Wen Qianfang.

The monster rushed extremely fast, jumping one step at a time, rushing from the eighteenth floor to the seventeenth floor in an instant, suddenly jumping down from the gap in the stairwell, and hitting the ground like a cannonball, the dust splashed up was as high as a calf, and the corridor trembled.

Wen Qianfang was frightened, and even rolled and climbed to turn around and run up.

"Roar—"

The monster opened its mouth and roared, and pounced at an extremely fast speed, and four sharp bone spurs pierced the back of Wen Qianfang's neck. Wen Qianfang spat blood in his mouth, and he couldn't say half a word with a "ho-ho" sound in his mouth, his body twisted twice, and he fell softly.

Nie Yuqian was so frightened that her whole body stiffened, and she couldn't go up or down when she stood in the middle of the stairs.

It was so fast that she couldn't escape.

"Qianqian, how's it going?" Ye Xuanyi's voice came from the smart watch on her wrist.

Nie Yuqian subconsciously licked her dry lips and shouted, "Wen Qianfang is dead, I was blocked in the stairwell by monsters......"

"It's coming, ahhh

The terrible screams were filled with fear and came to an abrupt end like a guillotine. There was no more sound, only the heavy footsteps of the monster leaving.

"Qianqian-" Ye Xuanyi was heartbroken, and kept calling out to Nie Yuqian to the bracelet, and the tears in the corners of her eyes couldn't stop flowing.

"Qianqian, Qianqian." Ye Xuanyi did not give up and called out her beloved couple over and over again, but there was no response.

"Xuanyi, help me up, I'll save her."

"Yes, Qianqian is not dead yet, you still have heart boosters to save her." Ye Xuanyi was overjoyed, hurriedly wiped away the tears from the corners of her eyes, and reached out to help Du Chao, "Please hurry up." ”

"I know."

Du Chao reluctantly got out of bed and stood, slid the smart bracelet on his left wrist to exchange for a bottle of stimulant, quickly injected it into his body, and without saying a word, grabbed the saber and ran out of the door.

Li Canmei saw clearly on the side, she originally thought that the bracelets on Du Chao and Ye Xuanyi's wrists were just ordinary electronic products, but she didn't expect that she could 3D print test tubes and medicines, and before she could ask, Du Chao had already run out.

"You're hiding a secret from me, aren't you?" Li Canmei couldn't wait to ask, "What's the matter with your bracelets and potions?" ”

"It's none of your business." Ye Xuanyi was in a state of confusion, she was in no mood to talk nonsense with Li Canmei, so she said impatiently, concentrating on talking to Du Chao, "Du Chao, you must be careful." ”

"Yes."

Du Chao replied briefly, clutched the saber and raised his hand to protect his head and face, and rushed into the stairwell like a whirlwind.

It only took him a few seconds to run from the fifteenth floor to the seventeenth floor, and at a glance he saw Wen Qianfang lying in a pool of blood, his body twisting strangely, like a drowning floating corpse.

Getting closer, Du Chao realized that Wen Qianfang's fatal injury was in the back of his neck, and the blood holes with four thumbs were thick enough to completely penetrate his cervical vertebrae, and there were no other wounds on his body, and it was very likely that he was fatally attacked by a monster from behind.

Du Chao suddenly remembered the three corpses he had seen in the ninth-floor elevator, two of which had wounds similar to Wen Qianfang's, one was cut open in the neck, and the other was pierced through the chest by a bone spur the thickness of a thumb.

It was a monster he had never encountered before.

The thought flashed, and Du ran up beyond Wen Qianfang's corpse.

Nie Yuqian was lying on the corner of the stairs between the seventeenth and eighteenth floors, lying on her back on the ground, her left chest was pierced in the heart, and the part of the attack was exactly the same as that of the deceased in the elevator.

"Qianqian." Du Chao shouted, squatted down to inspect Nie Yuqian's eyes, but fortunately, the pupils had not dilated.

Quickly swipe the interface of the smart bracelet, select the cardiotonic exchange, and the virtual projection will appear in front of you instantly.

Du Chao was overjoyed, and was about to confirm the exchange, when he suddenly felt that the stairs were vibrating, and there was a regular vibration.

"Damn, the monster isn't gone yet." Du Chao didn't have time to think about it, picked up Nie Yuqian's neck and legs, bent up and ran.

He didn't dare to risk injecting a cardiotonic here, in case Nie Yuqian couldn't regain consciousness before the monster came over, I'm afraid it would be difficult to escape the monster's pursuit. He didn't have the weapons he had at his disposal, and he wasn't sure he would kill a new type of monster he had never encountered before.

Thirty-six plans are the best plan, and we will get out of danger first.

The footsteps behind him were tighter and heavier, and Du Chao ran to the corner of the sixteenth floor, and when he turned around, he could already see the monster's thick calves.

"Roar."

The monster roared, and the old skill was repeated and jumped down from the railing of the stairs, landing on Du Chao's path like Tarzan.

Du Chao was stuck at the corner of the seventeenth and sixteenth floors, and the monster was landing at the exit of the corridor on the sixteenth floor.

It was impossible to rush over, and he couldn't continue to run, otherwise he would lure the monster to the fifteenth floor, and everyone would be threatened. It is not possible to continue to turn his head and run away, Du Chao will definitely not be able to outrun this monster with Nie Yuqian in his arms, and the terrain of the stairwell is conducive to him jumping.

The only way to live, only to fight, kill it to live.

Du Chao put down Nie Yuqian, raised the saber in his right hand across his chest, beckoned to the monster with his left hand, and said provocatively: "Comeon, Baby." ”

The chimpanzee-like monster fluttered its nose, its blood-red eyes flashed with a strange light, and it swayed its body with a roar and rushed up the stairs.

Du Chao was condescending, flashed the bone spur of the monster's right arm sideways, raised his knife to block the sweep of the monster's left arm, and used all his strength to raise his leg and kick the monster's right leg knee, and the monster fell sideways due to unstable footing.

Du Chao knew that these monsters were all mutated by human blood, no matter how strong their physique was, their body structure was the same as that of humans, and their joints were the same.

When he fought a giant monster comparable to O'Neill, he also attacked the monster's leg and cut off the monster's calf to successfully kill. Now that he was on the same level as the monster, it was convenient for him to attack the monster's legs.

"Huh."

Du Chao shouted violently, pushed away the monster's left arm, and stabbed the monster's chest with the saber in his right hand, slashing down like a bamboo.

The monster's fur was torn apart, revealing bright red flesh and blood oozing out.

If Du Chao was holding a fire axe, he would have to cut off one of the monster's arms, not to mention this confrontation, and now he only has a saber in his hand, and he can only choose the monster's vital attack.

The monster was injured, but the injury was not fatal, but instead aroused the ferocity of the beast, waving its arms and continuously attacking Du Chao's chest.

Du Chao retreated while flashing, and took three steps in a row until his back hit the wall and there was no way to retreat.

"Roar." With a shout, the monster stretched out its arms together and stabbed at Du Chao's throat and heart like a wind.

Du Chao waited for this moment, turned sideways to dodge the monster's attack, jumped high and waved the saber to cut into the monster's weak defense, grabbed the monster's hair with his left hand, and cut it fiercely with the saber in his right hand.

The monster is fully mutated, and the body is covered with hair, which strengthens the muscles, but the neck and throat are still weak points.

The saber was unusually sharp, cutting into the fragile veins like cutting butter, Du Chao cut it with all his strength and cut off the monster's spine with all his might, and the beheading was successful.

"Whew, whew." Du Chao casually discarded the monster's head, holding his hands on the wall and gasping for breath.

The battle was short, but it was dangerous, and he fought for his life, and if he couldn't dodge the monster's thrust, he would die.
