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

Zhang Yu returned to school to continue his studies. The incident with the Orthopedics and Internal Classic made Zhang Yu realize that his talent could only be applied to the knowledge he already possessed. It sounds a bit convoluted, but in essence, Zhang Yu's talent couldn't be created out of thin air, unlike other protagonists' cheat codes, which allow them to master all the knowledge in a particular area simply by applying them.

Zhang Yu's talent lies in integrating and strengthening the knowledge he has acquired. That's why, after mastering the meridians, he further integrated and strengthened his understanding of the Zheng Gu Nei Jing (Inner Canon of Bone Setting), which he hadn't studied before.

Therefore, Zhang Yu once again felt the importance of learning and wanted to acquire more knowledge. Moreover, Zhang Yu suspected that the triggering of his talent was also related to the amount of knowledge he had acquired.

Zhang Yu, back on campus, was reading in the library as usual, nothing had changed. But the other students were different, especially Hu Yifei's students, who were all beaming with joy.

Actually, when Hu Yifei first came back, they weren't like this at all; they were all like frightened birds.

Because Zhang Yu had spoken well of them to Hu Yifei, she was quite lenient with them when she returned, mostly turning a blind eye. However, they proved ineffective in getting away with it, and everyone became even more terrified of Hu Yifei's leniency.

Zhang Yu thought about how a teacher had come to see him a few days ago, asking if Hu Yifei was acting strangely, as she suddenly seemed like a different person after returning. Only after Zhang Yu repeatedly confirmed that Hu Yifei was alright and explained the reason for her sudden change in demeanor did he feel relieved. Then, Hu Yifei's students started acting recklessly in all sorts of ways.

"Old Zhang, quick, something's happened!" A handsome young man rushed to Zhang Yu's side and said anxiously.

"What happened again? Didn't you guys do your in-class papers for Professor Hu again?"

Zhang Yu looked up and saw that the person who came was Hu Yifei's student, Wang Jiawen, before looking down at his book again and asking casually.

The main problem is that this has happened many times in the past few days. This group of people really like to court disaster. Ever since they learned that Hu Yifei's attitude had become more gentle, this group of people has gone from one extreme to the other. They even dare to joke with Hu Yifei in class, and there are always people who dare not hand in their in-class papers.

Zhang Yu has encountered this several times already, and it's only been a few days. Zhang Yu doesn't know where they got the courage to not hand in Hu Yifei's in-class paper.

"No, that's not the main reason. Ms. Hu was asked to undergo a psychological test because of damaging public property. If she fails the test, the school will dismiss her."

Wang Jiawen shook his head and said anxiously, "We didn't expect things to be so serious. Hu Yifei used to vandalize public property all the time, but nothing ever happened before. Why is she suddenly being forced into psychological intervention?"

"Isn't Ms. Hu known for vandalizing public property? Why are we making her get tested this time? By the way, who among you has upset her this time?"

After hearing this, Zhang Yu realized it was the episode where Hu Yifei went to see the psychologist. But hadn't Hu Yifei's temper improved a lot lately? How could she still be damaging public property? What did these people do this time to make Hu Yifei so angry that her true nature was revealed?

"Hehe, it's not our fault. It's all because of Xiao Pang. He didn't do his homework and went to the radio station to say that Teacher Hu's menstrual cycle was irregular. Teacher Hu found out and got so angry that she vandalized public property three times in two days."

Wang Jiawen awkwardly shifted the blame, knowing that they had all gone a bit too far these past few days, especially Xiao Pang. Teacher Hu had already let him off the hook, but he still went to the radio station and talked nonsense, angering Teacher Hu.

"Little Fatty? You mean Shi Xiaoming? Has he gone mad? Just because Teacher Hu's temper has softened these past two days, he dares to provoke her? Doesn't he know that Teacher Hu listens to 'The Moon and My Heart' every day?"

Zhang Yu really wondered if people in this world would die if they didn't court death. If he hadn't transmigrated here before, Zhang Yu would have thought that Shi Xiaoming forgot to do Hu Yifei's in-class paper because he had too many subjects to choose from, which was understandable.

However, Zhang Yu had already made some inquiries. The courses that Shi Xiaoming had enrolled in didn't require submitting in-class papers very often, and most of them didn't require them at all. Even Hu Yifei hadn't had to submit one every time these past few days.

Logically speaking, he could have completed the task if he had done it normally. Moreover, Hu Yifei had assigned a paper in class these past two days, and he still hadn't done it. Zhang Yu was speechless.

Most importantly, Hu Yifei likes to listen to the late-night radio show "Your Moon, My Heart," which is something almost everyone in the school knows. It's even on the school forum. Apparently, a female student from the art department heard about it from one of Hu Yifei's scumbag boyfriends. The girl casually mentioned it while complaining about the scumbag, and then the post on the forum remained popular.

Zhang Yu really didn't know what Shi Xiaoming was thinking, actually going to Zeng Xiaoxian's radio station to accuse Hu Yifei. Wasn't he just blatantly defaming her? And to slander Hu Yifei in front of Nuolan, he really had a death wish.

Hearing Zhang Yu's complaint, Wang Jiawen gave an awkward laugh, then looked around before leaning close to Zhang Yu's ear to explain the reason.

Actually, it wasn't just Shi Xiaoming; they were involved too. The main reason was that they'd gotten addicted to the game lately, staying up all night every day and getting so excited they couldn't sleep.

A classmate suggested listening to Zeng Xiaoxian's radio show, since it was supposed to help people fall asleep. So a group of them started listening to Zeng Xiaoxian's radio to help them sleep. However, they didn't expect that Zeng Xiaoxian's show had been revamped. Now, because of Nuolan, they were all engrossed in listening to it.

As a result, a dozen or so of them would sleep during class during the day, and then play games until midnight with great energy, before listening to Teacher Zeng and Nuolan's broadcasts.

The result was obvious: sleeping in class during the day meant they didn't have time to do their in-class papers. Little Fatty was also an idiot; everyone else just borrowed other people's in-class papers to copy.

But Little Fatty insisted on writing it himself. However, he hadn't been paying attention in class, so he had no idea how to write it. Frustrated, he turned on the radio and listened to Nuolan's intellectual voice. On a whim, he called the hotline.

Then, other listeners found out. The group thought they were the only ones who knew, but they didn't expect that other people in the school also heard it. It spread like wildfire, and almost everyone knew about it, which is why Hu Yifei vandalized public property three times in two days.

Then the school heard about the rumor, and since Hu Yifei's personality had suddenly become more gentle a few days ago, but now it seems to have reverted to its old ways, and even become worse, the school thought that for the safety of the students, they had Hu Yifei take a psychological test.

Moreover, it wasn't as far-fetched as Wang Jiawen made it out to be. The school hadn't considered dismissing Hu Yifei; they just wanted to wait for the results. If Hu Yifei wasn't suitable for teaching, they could let her take another position. If all else failed, she could become a physical education teacher, and maybe she could bring back some medals and trophies for the school.
