Ning Xuan sat on the ground without looking up, because when she saw the way the lower body of the person was dressed, she could tell at a glance that she was not a girl and was unlikely to be the person she was looking for.

"Little sister, I want to buy this."

Ning Yu spoke to Ning Xuan in a pretentious deep voice, then took out his own corresponding pocket watch from his pocket, instead of picking up the music pocket watch for fishing on the street stall.

Ning Xuan raised her head and just as she gave a polite smile, a pocket watch dangled in front of her eyes.

"I'm sorry, sir, this is not for sale."

The pocket watch in front of her clicked open, but instead of the familiar melody she was familiar with, there was a family photo inside.

Ning Xuan's eyes widened slightly under the brim of her hat, and she immediately looked at the person who came.

Ning Yu took off the polarized glasses from his face, squatted down and looked at Ning Xuan with his amber eyes.

Finally seeing that familiar person again, Ning Xuan forced herself to suppress her excitement.

"If you're really interested, why don't we talk in private?"

She said calmly, her voice concealing her emotions just right, but this time Ning Yu still noticed her excitement.

"No, I want you to talk."

Ning Yu took the initiative and put away her pocket watch, inviting Ning Xuan.

Ning Xuan's expression was a little hesitant. She looked around, nodded silently at Ning Yu, and then quickly packed up the things on her stall.

But before he could finish cleaning up, he was stopped by Ning Yu.

"I'll take this music box."

She picked up the pocket watch from the stall that looked exactly the same, but had no photo and only had the function of a music box.

He put it into his pocket without any hesitation.

Ning Xuan didn't care, because this was just her "bait".

As for what her sister was going to do with it, she didn't have to care.

The more critical question now is, why did my sister discover me? It seems as if she has completely seen through my actions.

"Let's go."

Ning Yu took Ning Xuan's hand very naturally and walked with her in the Ark Base.

Both of them are obviously girls, but at this moment they are dressed as men. They look like a pair of good gay friends, walking hand in hand in a crowded place.

"elder sister?"

Ning Xuan didn't expect Ning Yu's action. Her hand was suddenly grabbed and her whole body trembled.

"What's wrong?"

Ning Yu put on his polarized glasses again, turned around and looked at Ning Xuan. The lenses reflected light, making it difficult to see her eyes clearly.

"We can talk later if you have anything to say, my dear sister."

Ning Yu smiled at her and without letting Ning Xuan say anything, she pulled her towards her apartment.

Ning Xuan's heart was filled with countless complicated emotions at this moment. She hadn't said anything yet, and her sister should have lost her memory of her.

How could it be? Now they still look as familiar as before? But it really feels so warm, it's my sister's hand. Not long after, the two of them walked to the door of Ning Yu's small apartment.

Ning Yu took the key out of her pocket and tried to unlock the door of the small apartment.

"Sister, you are in a very bad situation now."

"It's dangerous. You have to take me to a safe place."

Ning Xuan was about to speak anxiously when she was interrupted by Ning Yu, who even said the lines she was going to say directly.

"Sister, how did you know?"

Her face was full of disbelief, and she began to suspect that Ning Yu had discovered all her secret actions.

No, no, sister shouldn’t know so much.

Seeing Ning Yu was about to unlock the door again, she stopped Ning Yu's hand again.

"Sister, our conversation cannot be known to others, there might be..."

Before Ning Xuan could finish her words, Ning Yu had already opened the door of the apartment.

Strange patterns began to light up in her eyes, and a metal blade was silently extending from her hand.

Ning Yu suddenly turned around and gave her a look: "Believe me."

There was a strong and unquestionable look in his eyes, which made Ning Xuan obediently put away the metal blade in her hand.

She felt very uneasy at the moment, as this was completely different from her original plan.

"Xiaoyu?"

Shen Yiyue glanced over from the dining table and saw Ning Yu waiting outside the door with a handsome young man wearing a baseball cap.

"Sister Ning Yu, this is..."

Shen Qianqian looked up from the comic book and saw the handsome young man standing next to Ning Yu at the door.

Qianqian brand radar immediately sounded the alarm:

"Sister!! There is a love rival!!!"

"puff!"

Shen Yiyue was just about to take a sip of water when she immediately sprayed it on the dining table.

"You idiot, this is Xiaoyu's sister!"

Besides, even if he is really a love rival, is there anyone who would plot so loudly like you? ! Ning Yu brought a pair of slippers to Ning Xuan, walked in, threw her polarized glasses aside, took off her hat, and her flowing silver hair fell down immediately.

Ning Xuan walked in hesitantly and looked at Shen Yiyue who was wiping water on the dining table with surprise. She didn't expect that this girl also knew her identity.

Ning Yu had already walked over and helped her take off her hat. Her beautiful silver hair, as well as Ning Yu's, fell onto her shoulders as she moved.

"Wow!!!!!"

Shen Qianqian seemed to have seen some new world. Her eyes widened as big as bells and she hurriedly ran over with her short legs.

Circle around the two people, look left and right.

"There are two Ning Yu sisters!!"

She pointed at Ning Yu and Ning Xuan who looked very similar to her and shouted loudly.

"Hello, my name is Ning Xuan."

There was no other way at the moment, so Ning Xuan had to bite the bullet and introduce herself, with a million questions in her mind.

In the current timeline, Shen Qianqian has not seen the photo in Ning Yu's pocket watch, so it is inevitable that she would say this.

"Sister Ning Xuan is also very beautiful, just as beautiful as Sister Ning Yu."

Shen Qianqian had a cool expression on her face as she looked at the two pretty sisters, as if she was playing a game of spot the differences, trying to find the difference between the two.

"Okay, okay, go read your comic book."

Shen Yiyue hurried over and put the extra-large speaker back to its original position.

Standing next to Ning Yu, the three of them looked at each other.

"You may not know the situation yet."

Ning Yu brought the two people to the dining table and put away the large piece of paper that was originally used for planning.

It’s better not to tell Ning Xuan about the time travel for now.

"Sister, what's going on?"

Ning Xuan finally found an opportunity to speak and asked hurriedly. She was completely confused now.

"I know why you're here."

Ning Yu spoke.
