Chapter 1

"What does protein turn into after it enters the small intestine?" Ms. Liu, a biology teacher wearing glasses, was speaking with great enthusiasm in class. Years of teaching had transformed her from a gentle and charming young woman into a formidable woman. "Such a simple question, and some of you still get it wrong!"

The students below were drowsy. Senior year was the most critical period, but after multiple rounds of exams, the students had clearly become somewhat apathetic. It was unclear whether they were slow to react or distracted, and no one answered the teacher's question.

"What does it turn into?!" Ms. Liu's voice rose three octaves, trying to rouse the students' enthusiasm.

Still, no one answered. Ms. Liu tapped the desk and said, "Someone's answer was that protein turns into feces after entering the small intestine!"

"The examiner who saw this answer laughed and asked which class's teacher taught this. I was laughing too, wondering whose student would write such an answer. It turned out to be a student from our class, taught by me. You've really disgraced me!"

"Ha ha ha!"

The dull classroom atmosphere suddenly became lively, and the drowsy students burst into laughter.

Compared to boring knowledge, teenagers in their adolescence had a special interest in jokes and odd remarks.

Ms. Liu broke off half a piece of chalk and threw it at Xiao Ming, who was sitting by the window on the right. She said, somewhat angrily, "Xiao Ming! You're still sleeping when class is almost over! I'm talking about you! The one who wrote that protein turns into feces in the small intestine is you! Only your small intestine has this special function!"

"Ha ha ha!" The students were excited and looked at Xiao Ming.

Xiao Ming, who had been drowsy a moment ago, suddenly looked up at Ms. Liu, a bit confused.

Xiao Ming's eyes were a bit strange, different from his usual listless look.

Senior year students were in a severe rebellious and depressive phase. Last month, a top student from the city's No. 1 High School jumped from a building because she couldn't handle a teacher's scolding.

Thinking of this, Ms. Liu's tone immediately softened. "The college entrance exam is coming up. The teachers haven't given up on you, so you have no reason to give up on yourselves."

Xiao Ming tried to focus, feeling a bit uncomfortable with his own change.

Before the first Chinese class, he had experienced palpitations and shortness of breath. During class, he felt so uncomfortable that he rested his head on the desk. His thoughts became increasingly fuzzy, as if he were drowning and unable to breathe or escape. Then came the cold, and he lost consciousness.

When he woke up again, it was the second-to-last class of the morning, biology. Xiao Ming had been lying on the desk for several hours without any response. He was now cold and had a weak heartbeat, like a person who had come back to life.

At the same time, Xiao Ming had many vague memories. He felt he had lived for a long time on a highly intelligent planet called Pansaxing, where there were anti-gravity cars, floating houses, and interdimensional spaceships. The people there used a biological chip called an ev device for communication and gaming, and they lived on highly industrialized energy blocks and reagents. There were many more things...

Xiao Ming was a tech warrior on this planet, living by conquering technologically inferior planets to obtain resources.

The memories from the two worlds intertwined, and Xiao Ming suddenly stood up, staring around with wide eyes.

This action startled Ms. Liu again. "Xiao Ming, what are you doing?"

The students also stared at Xiao Ming, who was acting unusually.

In everyone's impression, Xiao Ming was a very low-key underachiever. He either slept or read novels during class, never causing trouble. His grades were consistently the worst in the class, and it would be a miracle if he could get into a junior college.

How could such a low-key and introverted student suddenly act so rashly in class?

Xiao Ming stood up as if under a spell and then staggered back to his seat.

Additional memories flooded his mind, and there seemed to be something inexplicable in his brain.

"Where am I?" Xiao Ming muttered to himself, his voice a bit loud.

"Ha ha ha!" The students who had been worried burst into laughter. Xiao Ming was really providing endless entertainment today!

"Xiao Ming, have you been reading too many novels, or has your brain short-circuited?"

"Where am I? This is a dream."

Xiao Ming suddenly had a thought: he must have died suddenly and then come back to life.

The past memories were close yet distant.

His family was quite ordinary. His father was a worker at a local paper mill, and his mother sold groceries outside their neighborhood. Xiao Ming was their only child.

Unfortunately, the once-excellent student Xiao Ming became unbalanced after missing out on a place at Jiangcheng No. 1 High School due to an accident in the middle school entrance exam.

Throughout high school, Xiao Ming gave up on himself, and his grades plummeted. When he came to his senses, it was too late. High school courses couldn't be caught up in a day or two. He had tried, but the repeated exam failures and ridicule from teachers and classmates made him withdraw into himself.

He completely gave up on himself, becoming immersed in the virtual worlds of games and novels. Long nights of staying up, irregular eating, and lack of exercise weakened his body, turning a once-healthy young man into a frail one.

Last night, he had stayed up reading novels until 5 a.m. and came to school without breakfast, eventually dying in class.

"I'm still alive!" Xiao Ming, who had experienced life and death in a short time, was very afraid. He cherished the air and everything around him.

But Xiao Ming also felt that he had lived for several decades on Pansaxing. That world was so real and long. He blinked hard, looking at this world. "Everything is so real!"

Xiao Ming confirmed that he was in the year 2017, November 20th. The most advanced electronic products were the iPhone X and Huawei Mate 9; the most advanced civilian transportation was the jet aircraft...

There were no anti-gravity cars, no interdimensional spaceships, no energy blocks...

But why did the problems on the blackboard seem so simple, and he knew them all?!

Xiao Ming's eyes widened in shock. He was sure he knew all the problems on the blackboard! The key was that he didn't learn them at Jiangcheng No. 3 High School, but in the memories of Pansaxing!

Was the death dream real?

Ms. Liu was still criticizing the many low-level mistakes in the exam, such as not being able to calculate simple genetic diseases, unclear experimental logic, and, of course, the lowest-level mistake: Xiao Ming's answer that protein turns into feces in the small intestine.

Seeing Xiao Ming's lifeless state, Ms. Liu was furious. "Xiao Ming, are you done? Come on, come to the front and explain!"

Xiao Ming was stunned for a moment and then walked to the front, feeling dizzy.

"Are you really going to come up?" Ms. Liu was very frustrated with this student today and planned to talk to the homeroom teacher. These underachievers, should they be encouraged to go home and rest, since they won't pass the high school entrance exam anyway?

Under the bewildered gazes of the students, Xiao Ming wrote on the blackboard with chalk.

He drew a flowchart of the complete process of protein absorption in the human body. Xiao Ming felt he had really learned this knowledge and learned it very well!

A few minutes later, the metabolic diagram of protein was complete, stunning the students and Ms. Liu.

For ordinary students, protein metabolism was not a difficult topic, but for underachievers, it was different.

Even if Xiao Ming had just read the book, being able to write it on the blackboard was already impressive!

Ms. Liu was also impressed by Xiao Ming's neat and sharp handwriting, which was even better than the Chinese teacher's!

Xiao Ming put down the chalk in a daze and said to Ms. Liu, "Exogenous proteins are broken down into amino acids and small peptides in the intestine... Small peptides are then completely hydrolyzed by aminopeptidases, carboxypeptidases, and dipeptidases, entering the bloodstream."

Yes! He really knew it all!

Xiao Ming was amazed!

After speaking, Xiao Ming returned to his seat.

The class burst into热烈的掌声！Ms. Liu也主动鼓掌！

令人惊讶，学渣 Xiao Ming 竟然有如此表现！

此时，Xiao Ming 的脑海中浮现出一些东西。

---

The class burst into enthusiastic applause! Ms. Liu also applauded.

It was surprising that the underachiever Xiao Ming could perform so well!

At this moment, something appeared in Xiao Ming's mind.
