Why does the world show a health bar? !

Here's the revised translation with all non-English words removed:

---

Li Mo woke up from his bed. His eyes were lifeless as he stared at the ceiling. The dim light in the room made it hard for him to see what the ceiling looked like. Having just arrived, he wasn't very familiar with the ceiling of his own home.

Usually, the first thing he did after waking up was to get out of bed under the stimulation of sunlight. He would wash up, eat breakfast, and head to the hospital. The only two times he went to school, the first time he strolled over leisurely since he was already late. The second time, he jogged and barely made it through the school gate, but the first class had already started.

Today was different.

"Now, it's… night?"

Li Mo couldn't believe it. In the more than a week he had been in this world, he had never seen the night. Groping in the darkness to find the light switch, Li Mo suddenly realized he had almost never turned on the lights in this room. Fortunately, he pulled open the curtains and, with the help of the faint moonlight, found the light switch.

He pressed it gently, and the room brightened considerably. He glanced at the clock hanging on the wall.

12:05.

"Did I wake up at midnight? Why? Why wasn't it 8 a.m. like usual?"

Li Mo pressed his temples. The situation before him felt troublesome. Was today special? Or had his strange illness healed? If the illness was truly gone, then should he enjoy his youth once again?

He knew Hiratsuka. In the past, his attention had been entirely focused on his illness. Knowing that this world was a slice-of-life setting was fine, and even if supernatural elements were added, it wouldn't matter. His physical health was what truly mattered.

So, what should he do next?

At midnight, he no longer felt like going back to sleep. He had collapsed at 4 p.m. and slept until midnight—a full eight hours of sleep. Moreover, during the past period, he had spent sixteen hours a day sleeping. If he slept any longer, his body might rust.

"Well, first, I'll take a bath. I'll deal with the midnight stuff later."

Li Mo had plenty of experience with staying up late.

...

...

The sun was diligent. People could take leave from work, but the sun couldn't, because there was nothing to replace it. If one day the sun disappeared, the world would be destroyed.

Li Mo silently looked around. He was now in a classroom. A teacher in his thirties or forties, balding, stood on the podium, explaining the lifelong enemy of students—mathematics. Many students in the class were listening to the teacher's explanation. However, there were also a few, like him, who were zoning out.

Li Mo didn't care much about what the teacher was saying. He was more focused on something else. Even though he had noticed it earlier in the morning, he still felt amazed and surprised. Because the world had undergone a dramatic change.

A change that overturned his worldview.

Strange things had appeared above everyone's heads. At the front were some recognizable symbols and text, while at the back were red bar-like objects with percentage numbers displayed inside.

「???（96%!）(MISSING)」

「???（95%!）(MISSING)」

「???（97%!）(MISSING)」

...

It looked something like this.

In the large classroom, every student had these above their heads. Depending on the distance, the size of the strange symbols and bar-like objects would change. But when he focused his attention on a person, the corresponding text, symbols, and bar would enlarge, allowing Li Mo to notice the details immediately.

Was this a game?

It felt very much like a game. When Li Mo left his house in the morning and saw everyone on the street with these things above their heads, his inner turmoil and shock were unimaginable. His first reaction was that these were like health bars, but he wasn't a player with the mindset of "if it has a health bar, it can be killed."

He only had one life, while players had countless lives.

Perhaps this was his golden finger (cheat ability). He would research it more after returning home.

The strange illness from before might have been triggered by this golden finger, but he hadn't figured out the exact reason yet. School wasn't a place where he could freely explore, so he would investigate once he returned to the comfort of his home. Perhaps because of the torment of the illness, Li Mo didn't place much importance on this疑似 golden finger.

He averted his gaze and began to consider another matter concerning himself. Earlier that morning, he had contacted Hiratsuka via phone, informing her that his strange illness seemed to have healed. They also discussed his academic situation.

Given a second chance at youth, anyone would likely focus on their studies. Li Mo wasn't a genius who could confidently drop out like Bill Gates and make a name for himself. He was just a working-class individual whose edges hadn't yet been worn down by society.

Having been a working-class individual, he understood the importance of learning. Now, as a student, studying was his primary job. It was only natural to put effort into it here. As for the math class, Li Mo already knew the points the teacher was explaining, likely due to the original host's memories merging with his own. Problem-solving methods and knowledge points weren't an issue—what mattered in math was practicing to develop thinking skills.

Li Mo recalled a university classmate from his previous life, a bunkmate who was terrible at math. What Li Mo understood at a glance was like a foreign language to his friend. He didn't know how to jump from one step to the next.

The young man sitting by the window turned to look at the courtyard outside. He was in the last seat by the window, and although it wasn't the protagonist's seat, Li Mo didn't feel discouraged. Being able to see the scenery outside was good enough.

He had also considered returning to his home country. After all, Japan was an unfamiliar place. But the familiar places from before no longer existed. Early on, after crossing over, while seeking medical treatment at the hospital, he had dialed a phone number he knew by heart, even adding "+86" to the front, but the response was that the number didn't exist. That was when he realized the world had changed. As for the original host's father, he had already remarried, and returning now would inevitably require contacting them.

Li Mo had also thought about not contacting them. But if they found out he had returned, they would surely reach out. It was just a matter of saving face—despite the awkwardness and lack of affection, they would still go through the motions of responsibility in front of outsiders, making things exhausting for both sides. Having glimpsed the original host's memories, he knew it was better to stay here. At least the mother here was a cold person who only cared about the alimony and nothing else.

This was fine.

"Li Mo, right? Please come with me."

"Is it the teacher who's looking for me? And is it the top student?"

Li Mo examined the girl before him.

Her smooth, jet-black hair and delicate features exuded coldness. Although she wore the same uniform as the other girls, she stood out distinctly.

Class 2-J was the international class, with many students who had returned from overseas or studied abroad. The class's academic performance was two to three percentage points higher than the regular classes. Yet, even in such a class, this person stood out exceptionally.

The top student in her grade.

"It's me. So, please come with me."

"I haven't had lunch yet. Also, I didn't prepare a bento."

"I have one."

"Alright."

Li Mo quickly packed up the study materials he needed and followed the top student out of the classroom. Along the way, many students who hadn't yet gone to the cafeteria saw them and began to gossip.

Indeed, the combination of a mysterious foreign exchange student and the top beauty of the grade was quite eye-catching.

He felt a little nervous.

Li Mo wasn't the type to enjoy being in the spotlight.
