Lu Yining raised her hand in dissatisfaction and slapped the hand that was causing trouble on her head.

As if sensing Lu Yining's movement, Lu Yubai's palm retracted slightly.

"Bang——"

The slender hand fell, and with a loud crisp sound, it slapped her head...

Lu Yining glared at Lu Yubai with an accusing look, "Why are you shrinking?"

Lu Yubai blinked innocently: If I don’t back down, am I just waiting to be beaten by you?

Understanding the meaning in Lu Yubai's eyes, Lu Yining said coldly, "Just wait! We're enemies now! There's no way this can go on!"

Seeing her like this, Lu Yubai couldn't help but feel a little funny, but he still knew that he had pissed off his fifth sister at the moment, and the key was that his fifth sister seemed to be quite vindictive.

If I don't apologize now, this matter will probably never be resolved.

He lowered his head sincerely and said, "I'm sorry, it's all Fourth Brother's fault. Will Fourth Brother treat you to a delicious meal to make amends?"

As he spoke, Lu Yubai observed Lu Yining's expression. Seeing that Lu Yining's expression relaxed a little after he finished speaking, he continued: "Please forgive Fourth Brother. I beg you, for the sake of delicious food, please forgive Fourth Brother, okay?"

[Okay, okay.]

Lu Yining cleared his throat: "I'll forgive you this time, and it won't happen again!"

Lu Yubai breathed a sigh of relief, a smile spreading across his lips: "Okay, I promise it won't happen again!"

Strangely enough, he is an introvert. When he interacts with people he is not very familiar with, he gets very nervous, his heart beats faster, and he feels extremely uncomfortable all over.

But maybe it was because of their blood relationship, but when he was with the fifth sister, he didn't feel uncomfortable or nervous. Instead, he felt very comfortable and natural, as if... they had known each other for a long time.

Lu Yubai took Lu Yining back to his dormitory. It happened that his dormitory had two rooms, one for him and one for Yining, which was just right.

"I'm sorry, I haven't bought you sheets, quilts, pillows, and other things yet. When Fourth Brother is done with his work, I'll take you there, okay?"

He was indeed not lying. Originally, he had nothing to do that day, but when he was about to return to school, he received a message from his friend saying that the scientific research results they were studying had made further progress.

Knowing he was going back to school today, his friend hurriedly asked him to come over. Since he really wanted to see the latest progress, he decided to go to the lab first and then go for a walk outside the campus with his fifth sister.

Lu Yining waved at him sympathetically: "It's okay, go ahead, I'll take good care of Ji Ji!"

"It's not a big deal. Go do your thing. I have to take care of my own business. Once Fourth Brother leaves, I'll go look for Zhao Kaihan."

Lu Yubai, who had been quite confident in Lu Yining, now frowned tightly, and a look of worry suddenly appeared on his face.

He really wanted to say, why not wait until he comes back, and then go out together to find Zhao Kaihan?

But after struggling for a moment, he decided to let go and not interfere with Lu Yining's actions.

Before leaving, he warned Lu Yining, "If you encounter any danger or any problem that is difficult to solve, come to the lab building and find me immediately, or call me. Got it?"

Lu Yining nodded obediently like a primary school student: "I know."

Seeing that she really took his words to heart, Lu Yubai turned around and walked out.

[Wuhu ~ Let’s go play ~]

…

"Hello, is there a student named Zhao Kaihan here?"

Lu Yining was fully armed, covering herself from head to toe. She deliberately lowered her voice when she spoke.

The student being asked first looked at her outfit in surprise, staring at it for nearly a minute, then seemed to realize that it was impolite, and quickly withdrew her gaze from Lu Yining.

"Yes, yes, there is this person in our class. May I ask who... are you...?" she asked hesitantly.

"I'm her sister's friend, and I came here to give her something."

Hearing this, the guard on that person's face dissipated a little, and she said "oh oh" twice: "Wait a moment, I'll go in and call her."

"But." The man was about to turn around, but seemed to think of something, stopped, and looked at Lu Yining doubtfully: "Have I seen you somewhere before?"

Well?

Lu Yining's body stiffened. You can see all this?

She quickly lowered her head and pretended to be calm. Of course, her face covered by a black mask and her eyes sealed by black sunglasses did not show any sign of panic.

"No, I have an ordinary face. I guess I look similar to others."

The man's frown remained, and he said doubtfully, "Maybe."

After a while, Zhao Kaihan was called out.

But at this moment, her face was a little cold: "Who are you?"

She did have an older sister, but she was aloof and a workaholic, not particularly sociable. Her sister's only friend was also her confidant, and she had met her sister's confidant several times, but she wasn't like the one before her.

Her sister's confidant is taller, not as short as her.

She also likes to keep her hair short and she never has long hair.

Besides, she had just met her sister's best friend two months ago, and back then she had short hair. There was no way she could have grown her hair out so quickly in two months. The hair of the man in front of her was almost down to her waist.

Therefore, this person could not possibly be her sister's confidant.

So, who is she?

Zhao Kaihan looked at Lu Yining with scrutiny. Similarly, Lu Yining was also looking at Zhao Kaihan. She was silent for a while before she spoke: "I came here specifically to see you. Come on, come with me for a cup of milk tea. I want to tell you something."

Lu Yining turned around and walked forward a few steps. He didn't hear any footsteps from behind. Lu Yining turned his head slightly and looked back, and found that Zhao Kaihan was still standing there without moving.

"About Luo Fengzhen."

Her cold figure moved slightly, then she raised her eyes and looked at Lu Yining. After a while, she finally took a step and followed Lu Yining.

Raising an eyebrow, Lu Yining thought to himself, "This name really works! If I had known this earlier, I wouldn't have wasted so much time talking about it! I should have just said Luo Fengzhen's name."

…

Zhao Kaihan thought that after Lu Yining bought the milk tea, she would sit down and drink it directly in the milk tea shop, but she didn't seem to have that idea...

After buying the milk tea, she asked her to follow.

How should I put it...

At this moment, she felt a bit like a servant following behind the young lady?

Seeing that Lu Yining was still walking ahead and showed no intention of stopping, Zhao Kaihan became impatient. At the same time, a hint of caution flashed in her eyes: "Where are you taking me?"

"Oh, the hotel."
