Ning Yu smiled and refused.

"Sister, you don't want that lovely girl to encounter any difficulties, right? She seems to have a sister living with you."

Ning Xuan remained calm, but this time her words were a naked threat.

"bass!"

In a moment when no one could see clearly, Ning Yu had a beautiful straight knife in her hand, with a blood-red butterfly decoration hanging on the handle.

The blade was now on Ning Xuan's neck.

"How about I make you disappear from the face of the earth within 10 seconds?"

Ning Yu's eyes were filled with murderous intent, making everyone feel cold all over.

Ning Xuan looked at Ning Yu in surprise, her lips moving as if she wanted to say something, and her eyes actually turned red.

As if something incredible had happened, her body was even shaking slightly, but it was definitely not because of fear.

But very sad.

Some tears overflowed from Ning Xuan's eyes, flowed down her cheeks, forming transparent tear marks.

"Sister, I never thought that one day you would treat me like this."

Her words revealed her sadness, and Ning Yu could clearly see that her feelings were not fake.

Did you have a good relationship with her when you were young?

Ning Yu didn't know exactly, but now looking at Ning Xuan crying, Ning Yu guessed that if she cried one day, she would probably look like this?

"When you threaten others, have you ever thought that they might want to kill you?"

Ning Yu did not put away the knife. He still looked at Ning Xuan indifferently, as if he was looking at a stranger.

The bodyguards behind Ning Xuan finally reacted and raised their guns, each of which was equipped with a silencer.

But there was inevitably hesitation between their actions. After all, these two people were sisters. If one wanted to kill the other, should they stop her? What made them raise their guns now was purely instinctive reaction and professional ethics.

"Are you crazy? Put the gun down!"

Ning Xuan suddenly gave the order in a stern voice, completely changing her gentle manner when she was talking to Ning Yu just now, and her tone was full of unwillingness to refuse.

The bodyguards were actually very embarrassed now. After receiving the order, they could finally put down their guns, but they couldn't help but look at the knife in Ning Yu's hand.

I was afraid that she would really kill Ning Xuan with a knife, and then I would have no way to explain myself.

Ning Xuan finally woke up from her inexplicable grief. She completely ignored the blood kite that Ning Yu placed on her neck, and took a step forward.

He held Ning Yu's hand tightly again and spoke seriously.

"I was too anxious. I didn't want this to happen, but my sister's condition is really very dangerous!"

Ning Yu touched Ning Xuan's hand and felt that her hand seemed much colder than that of ordinary people, as if all the heat in her hand had been taken away.

She suddenly had an idea and a system prompt sounded in her mind.

[Your friendship level is: Intimacy]

[The origin of the target detected is: no value]

[No origin ability to replicate was detected]

When Ning Yu heard the word "intimacy", she thought she had the ability to copy again, but she didn't expect that Ning Xuan's origin was actually a very strange [worthless].

What does this mean? Not even an origin ability.

However, since the friendship level is [Intimate], it means that Ning Xuan really has no ill will towards me, so theoretically I have reason to believe her.

But Ning Yu still asked as usual: "Why should I believe you? You were threatening me just now."

Ning Xuan pursed her lips when she heard Ning Yu's words, then took a deep breath and said:

"That makes sense, since what I just said has been heard."

Ning Xuan's right eye suddenly became bright, and countless inexplicable lines flashed in the middle, and something started to move.

Ning Yu was very familiar with this logo.

"ah!!!!"

"Uh uh."

Ning Xuan's figure suddenly disappeared from Ning Yu's sight, but her target of attack was not Ning Yu, but all the bodyguards in the room.

They suddenly covered their necks, and some of them bled from the gaps between their hands as they covered the wounds. Some of them raised their hands too slowly, and the blood splattered on the wall.

Ning Yu was the only one present who saw clearly Ning Xuan's movements, as well as the metal blade that suddenly "grew" in her hand.

When Ning Xuan appeared in front of Ning Yu again, the room was full of corpses except for the two of them.

Ning Xuan took out a handkerchief and gently wiped the blood on the blade. As the red blood was wiped clean, glowing lines appeared on the blade.

She opened her hands, and the blade in her palms seemed to be connected to some device, and Ning Xuan directly received it from her palms into her body.

Ning Yu looked calm. This was just a small incident for her. However, she was puzzled.

"Why do you do this?"

"Because they heard my true thoughts. If I don't die now, I will die later."

Ning Xuan said nonchalantly, as if she didn't care at all about the lives of those people.

"It sounds like you're going against your organization by coming to help me?"

Ning Yu continued to ask.

"Sister, have you really forgotten? Existences like us are destined not to be loved by anyone or anything. I only have you, and you only have me."

Ning Xuan then looked at Ning Yu again, but her temperament had completely changed at this moment. She was no longer the cute little sister who missed her sister.

Her eyes became deep and lonely, as if there was nothing in the world worthy of her care except Ning Yu.

"Do you believe me now?"

Ning Yu was silent after hearing this, and thought carefully for a while. Instead of answering her directly, she asked a new question: "Why do you want to accept the transformation of cyborg body?"

Ning Xuan was stunned when she heard this question, and suddenly turned her eyes to the side with a gloomy expression:

"Sister, you must have seen Yue Ji, right? It seems that you really have lost your memory."

Amnesia? I'm not your sister, okay?

But this is not the point. Ning Yu just heard a shocking word from her mouth:

"How do you know Tsukishime?"

Ning Yu had never told anyone about this. She had only seen Yue Ji in her dreams, and it was Yue Ji herself who told her this name.

"Of course I know. If it weren't for us, how could Yue Ji exist?"

Ning Xuan seemed to have finally accepted the fact that Ning Yu had lost her memory and smiled helplessly.

"So why did you accept the prosthesis?"

Ning Yu wanted to continue asking questions, but was immediately interrupted by Ning Xuan.

"None of this matters, sister. You just need to know that I'm not here to harm you. On the contrary, sister is facing a very serious crisis right now."

"Come with me now, I will take you to a safe place, where no one can find us!"

She looked serious, even a little anxious.

"What crisis? Tell me about it."
