Ning Yu stood behind Ning Xuan and reminded her gently. Of course, she didn't intend to take action, but she told Ning Xuan the weaknesses of the two mutated zombies.

Ning Xuan didn't look back. She raised her left hand and gave Ning Yubi an "OK" gesture.

Ning Yu noticed that her ankles and wrists were beginning to be covered with prosthetic devices, like ankle and wrist guards.

There was something like a jet hole on the device. As Ning Xuan moved, Ning Yu saw the bright flames spewing out of it. It seemed to be some kind of booster device that could speed up Ning Xuan's movements.

All the zombies, including the two mutated gluttons and the greedy one, rushed towards where Ning Xuan was.

Ning Yu was standing behind her, and she looked like she had the aura of a single man blocking the pass from ten thousand.

[You killed an ordinary zombie and got points*10]

[You killed an ordinary zombie and got points*11]

A series of points prompts began to sound, and the ordinary zombies that rushed over first had their heads chopped off by the knife held by Ning Xuan like thriving bean sprouts.

The mechanical device on her body continuously and rapidly spewed out flames of varying sizes, quickly moving and adjusting Ning Xuan's body.

Such rapid movement was as if he was controlling his own hands and feet, so flexible.

Ning Yu was amazed at this exquisite design. Even if an ordinary person came here, if he could be transformed into this, he would probably have considerable combat effectiveness.

It’s a pity that ordinary people cannot be transformed to this extent.

Speaking of which, Ning Yu had forgotten to ask just now, why Ning Xuan needed to undergo cyborg transformation, but her sister didn't need it?

Ning Xuan's figure was weaving in and out of the zombie group. Wherever her swift figure went, there were corpses everywhere. Soon she encountered three mutated zombies.

Ning Yu discovered that whether it was the Glutton's claws and bites, or the Greedy's sharp sickle attacks, Ning Xuan did not deliberately dodge.

Any attack that is not dodged will be blocked by the curved barrier, creating ripples.

So Ning Xuan's attack was very direct. With the help of the prosthetic device on her body, her speed was not slow at all, and the battle with several mutated zombies did not last too long.

[Ding! You killed a low-level mutant zombie glutton, and got points*500]

[Ding! You killed a low-level mutant zombie glutton, and got points*500]

[Ding! You killed a low-level mutant zombie greedy, and got points*500]

Along with the last prompt tone, the alloy steel knife in Ning Xuan's hand pierced through the greedy man's small eyes and killed it directly.

Ning Yu also took the points of all the zombies here.

She loosened her hand and released the Blood Kite, which absorbed the blood of the zombies on the ground to gain weapon experience points.

"How's it going, sister."

Ning Xuan didn't need to walk when she was in combat mode, but floated directly back to Ning Yu.

"You are strong."

Ning Yu nodded slightly to show her approval, and suddenly she saw a few traces of zombie blood on Ning Xuan's pure white hair.

She walked forward, took out a handkerchief from the space, and gently wiped off the blood stains on Ning Xuan.

It was clearly just a very ordinary action, but Ning Xuan seemed to be stunned, and even her speech became slower: "Sister."

Hearing Ning Xuan's words, both of them were stunned.

Ning Yu was stunned because this had become her subconscious action. Every time after fighting side by side with Shen Yiyue, she would help Shen Yiyue wipe the blood off her body.

At this moment just now, she seemed to overlap Shen Yiyue's shadow with Ning Xuan. Even the action was very intimate and there was no hesitation.

Ning Xuan was stunned because she seemed to see the shadow of her childhood and recalled many memories of the past.

It’s a pity that she didn’t realize Ning Yu’s true thoughts.

Ning Yu reacted and acted like nothing had happened. She put away her handkerchief and put it back into the space.

He reached out and grabbed the blood kite that flew back, and his eyes turned bright red again.

She put away the blood kite as if nothing had happened, and walked towards one of the rooms that looked like a hotel. She took a few steps before speaking.

"Let's go. We still need to interrogate this guy. Bring him here."

The man who was dragged to the ground by Ning Yu was still unconscious.

Ning Xuan was still immersed in the action just now, and suddenly came to her senses, picked up the man on the ground, and walked over behind Ning Yu.

"ah!"

The man was awakened by a slap in the face. When he looked up, he suddenly found two beautiful silver-haired girls in front of him.

He felt a blur of consciousness and a piercing pain in his chest, but the wound seemed to have been treated in some rough way, and it was still a bloody mess and even a little charred.

The temperature in the room began to drop again, but after a while, the man suddenly covered his head and howled miserably.

It was obvious that he originally wanted to use his awakened ability, but it seemed like he had suffered some backlash.

"What did you do to him?"

Ning Yu looked at Ning Xuan beside him in confusion. She seemed to have inserted something into the man's body just now. She must have tampered with the prosthetic part of the man's body.

"Made a small modification to his awakening circuit."

Ning Xuan winked at her mischievously and gave Ning Yu a brief explanation.

It was a long time before the man stopped howling on the ground. He gasped with difficulty and did not dare to try to use his ability again.

"Ms. Ning Ningxuan, how could you..."

The man recognized Ning Xuan's lake blue eyes, which were different from Ning Yu's, but his eyes were full of disbelief.

He clearly remembered that Ning Xuan also accepted the order to find Ning Yu, and suffered heavy losses and was even stabbed by her beloved sister.

Why is he standing next to Ning Yu now?

When he thought of this, he finally realized what was going on.

"As you can see."

Ning Xuan smiled at him indifferently. That smile was not as gentle as the one she smiled at Ning Yu. Instead, it revealed a coldness and cruelty.

The sharp blade in her hand pointed at the man's modified body, and threatened in a tone that the man could understand: "Who else will be sent here? It won't be just a small character like you, right?"

Ning Yu looked at Ning Xuan who was interrogating on her behalf and felt that she seemed very skilled as well.

The man looked at the place where he was threatened, and recalled the pain that had just rushed into his head, and he couldn't help but shiver.

After hesitating for a few seconds, he said, "We are just the vanguard, there are more behind us..."

The man was about to say something else when his head suddenly began to tremble uncontrollably and a strange light shone from his eyes.

"What did you do to him?"

Ning Yu looked at Ning Xuan in confusion, but Ning Xuan suddenly pulled Ning Yu back.

“Boom!”
