In Love Apartment, I used a cheat to develop the Multiverse Gate.

For the next few days, Zhang Yu went to school as usual during the day and taught Teacher Zeng how to practice the Zheng Gu Nei Jing (a classic text on bone setting) after school. Since Lu Ziqiao helped him practice his finger strength during the day, Zhang Yu only needed to check on his finger strength after school.

Then he was specifically taught the acupoints, meridians, and massage pressure for the ankle joint. Over the past few days, Zhang Yu watched as Teacher Zeng went from knowing absolutely nothing to quickly mastering all the meridians and acupoints of the ankle joint.

Finally, there's finger strength, power, and the intensity of the massage. Incredibly, Teacher Zeng reached Huang Huihong's level in just three or four days, though only in the ankle joint area. Even so, Zhang Yu was still very impressed with Teacher Zeng.

However, just when Zhang Yu thought that Teacher Zeng was a martial arts prodigy and was preparing to teach him more, Zhang Yu realized that Teacher Zeng really was a martial arts prodigy. Because other people's talent lies in martial arts, but Teacher Zeng is different. His talent in martial arts lies in the peculiar, the peculiar.

What's strange about Teacher Zeng is that he only knows the chapter on ankle joints; he doesn't know any of the other chapters.

It wasn't that Zhang Yu didn't teach him. After seeing how quickly Teacher Zeng mastered the ankle joint, Zhang Yu tried to teach him other chapters as well. But no matter which chapter it was, even if it was just about the acupoints next to the ankle joint, Teacher Zeng couldn't learn it at all. But as soon as Zhang Yu mentioned the ankle joint, he understood it almost instantly. Isn't that amazing?

Zhang Yu even suspected that Teacher Zeng's learning talent was specifically created for Hu Yifei, which is why he could only learn the ankle joint section, which was helpful to Hu Yifei, and couldn't learn anything else. In fact, Zhang Yu had tried to trick Teacher Zeng into thinking it was the ankle joint chapter by using other chapters, but it didn't work; he just couldn't learn it.

So, in reality, if Hu Yifei were to suffer injuries all over her body, then Teacher Zeng would be able to fully master the entire *Orthopedic Internal Classic*. Of course, this is just a joke; who in this world could possibly hurt Hu Yifei, except perhaps herself?

"Congratulations, Teacher Zeng, you have completely mastered the chapter on ankle joints."

"Hahaha, I've finally mastered it! I've finally learned the Nine Yin White Bone Claw... Ugh, I've finally mastered the Bone Setting Inner Classic! Hu Yifei, here I come!"

That day, Zhang Yu finally confirmed that Teacher Zeng had mastered the chapter on ankle joints. Just after Zhang Yu announced that he had learned it, Teacher Zeng suddenly raised both hands, laughed loudly, and then ran out excitedly with Lu Ziqiao.

Watching Teacher Zeng run out, Zhang Yu suddenly felt that Zhanbo's words made sense. Practicing a single chapter could really drive someone crazy. Look at how Teacher Zeng had been driven insane by it.

Hopefully, he won't get too excited and "attack" Teacher Hu, otherwise he might end up worse off than Mei Chaofeng. Mei Chaofeng only became neither human nor ghost, but Teacher Zeng might actually become a ghost.

Thinking of this, Zhang Yu piously put his hands together and said "Amen," hoping that Buddha would bless him.

The next day, 3601, it was a day off, and Zhang Yu thought he would go and see how Teacher Zeng was doing, whether he was still alive.

In fact, Zhang Yu had come to 3601 to check Hu Yifei's pulse after school yesterday, because Zhang Yu noticed that Hu Yifei's foot swelling had gone down at a visible speed in the past two days, and she could walk with a hop, without even needing anyone's support.

Zhang Yu discovered that Hu Yifei had almost fully recovered, except for some issues with her ligaments, but it wasn't a serious problem.

Actually, when Zhang Yu took Hu Yifei's pulse a few days ago, he discovered that Hu Yifei, like Huang Huihong, also had qi in her body, and Hu Yifei's qi was much stronger than Huang Huihong's.

When Zhang Yu took Hu Yifei's pulse that day, he had already noticed that the Qi in Hu Yifei's body was constantly circulating around her ankle joint. However, there was still a lingering Qi, which caused Hu Yifei's foot to become more swollen. But that Qi was like a rootless duckweed, slowly disappearing under the circulation of the Qi in Hu Yifei's body. That's why Zhang Yu told Hu Yifei to just lie down and rest.

Just as Zhang Yu was about to knock on the door, he heard a loud bang from inside, followed by Zhanbo shouting anxiously from inside.

"Teacher Zeng, how are you? Wake up! Sister, please call an ambulance! Teacher Zeng is dying!"

Then Zhang Yu saw Nuolan open the door from 3602, completely ignoring Zhang Yu standing in front of 3601, and run straight in.

"Xiaoxian, are you alright, Xiaoxian?"

Zhang Yu followed her inside and saw Hu Yifei standing to the side watching Nuolan hugging Zeng Xiaoxian. The worried expression on her face immediately turned into indifference, as if this had nothing to do with her and she was just a bystander watching the show.

"Sis, why did you beat Teacher Zeng up like this? He was just trying to help you..."

Zhanbo looked at the "unconscious" Zeng Xiaoxian and rushed to Hu Yifei to stand up for Teacher Zeng, but before he could finish speaking, Hu Yifei interrupted him.

"Stop talking nonsense. Who told him to get close to me? It was a conditioned reflex. He was acting suspiciously. Who knows what he wanted to do?"

Hu Yifei clearly didn't want Nuolan to know that Zeng Xiaoxian had massaged and set her bones. Of course, it was also because she felt uncomfortable seeing Nuolan holding Zeng Xiaoxian, especially after she realized that Zeng Xiaoxian was still pretending to be unconscious in Nuolan's arms.

Actually, Hu Yifei wronged Teacher Zeng. When Zeng Xiaoxian was kicked by her, he did feel dizzy and faint for a moment. He was then shaken by Zhanbo and recovered when Nuolan held him.

However, firstly, Hu Yifei was still angry, and he didn't dare to face her when she was angry. Secondly, he subconsciously wanted to escape and didn't want to be caught between Nuolan and Hu Yifei.

Although he had already made up his mind, Teacher Zeng's personality was such that he was easily swayed, especially since he was particularly soft-hearted and didn't want to hurt others, especially since Nuolan was divorced, he was even more afraid of hurting Nuolan.

Zeng Xiaoxian can't stand seeing others looking lonely and helpless in front of him. Laura was like that before. How could he say that he had no idea about Laura's character after being together for eight years? Zeng Xiaoxian is a sensitive person. It's just that he didn't want to believe it and subconsciously avoided and comforted himself.

Moreover, he softens whenever Laura acts innocent. You have to understand that Zeng Xiaoxian is a person with emotional purity issues. After being together for eight years, he is still a virgin. With Laura's personality, do you think she wouldn't have a relationship with Zeng Xiaoxian? Impossible. You know, even if she has only met him once and knows that he is Zeng Xiaoxian's friend, she would still flirt with him.

So why is Zeng Xiaoxian still a virgin? Of course, it's because Zeng Xiaoxian subconsciously doesn't want to touch Laura. Even when Laura came back later, although Teacher Zeng softened and didn't want to hurt Laura, he still didn't cross the line.

That's why he kept dragging things out when he met Nuolan and Hu Yifei, wanting to escape and avoid facing them, hoping that dragging it out would solve the problem. He just didn't realize that sometimes dragging things out doesn't solve anything when it comes to relationships.

Actually, Zeng Xiaoxian is a passive type when it comes to relationships. He always hopes that the other person will take the initiative. As we know from the later plot, Nuolan took the initiative to confess, so he accepted Nuolan. Later, Hu Yifei expressed her feelings, so he followed his heart and accepted Hu Yifei.

This is also a point of criticism against him, because he accepted Nuolan when he liked Hu Yifei, and then accepted Hu Yifei while he was with Nuolan. There is no way to defend him for this.
