The sound of water from the shower gushing sounded in his ears, and the water falling on Li Mo made him feel particularly real.

He opened his eyes, and luckily, he was back again.

Were you dreaming just now?

"Hiss...", the water hit his arm, and he felt a little pain.

Lifting his arm, a small wound came into view.

"When did you get hurt?"

Li Mo thought of the scene frozen in the gray fog. He raised his leg and saw another wound!

"Is the gray fog real?"

"Is he in my head?"

"My brain is broken?"

He is a little confused!

"Li Mo, why did you take so long to wash? Mom is still waiting to use the bathroom."

Li Mo's mother's shout came from outside the door.

He couldn't care less, so he had to take a shower quickly. His mother had a habit of barging into the bathroom.

Li Mo sat blankly in front of the desk in the room, carefully touching the small wound on his arm. It was just a little scratch, very ordinary, and he didn't even need any medicine.

He suffers this kind of minor injury many times every year, and there are always a few big kids on the basketball court who use their weight advantage to commit fouls.

The wound is still an ordinary wound.

If the wound is real, is the gray fog just now also real?

Li Mo remembered that study task.

What will be the punishment if you fail to complete the task? The gray shadow man didn't say it clearly, he only said it was very serious.

At the dinner table, Li Mo was distracted and didn't even take a few bites of his favorite crab.

Li Mo's mother is reluctant to buy such expensive vegetables on weekdays. She thinks that school is about to start and she needs to make up for her son's expenses.

"Why don't you eat? Aren't you hungry after playing ball?" Li Mo's mother saw that Li Mo had no appetite, so she just dealt with it.

Li Mo lowered his head and picked up a few grains of rice in the bowl, "I'm not hungry. I just drank too much water and was full."

"Forget it if you don't want to eat it. Go do your homework quickly. School is about to start, and you still have to run around all day long." After saying that, Li Mo's mother put the crabs back into the pot. Li Mo knew that she was keeping them for his father.

She couldn't bear to eat it herself.

"I'm going back to the room." Li Mo said hello.

He was thinking about the mission issued by the Gray Shadow Man. What would happen if he failed to complete it?

The alarm clock in the room points to six o'clock, which means that he will start reading for six hours from now and can finish it at twelve o'clock in the evening.

Isn't it just reading for six hours? Li Mo finished the entire summer homework in one night.

Although the answers were all made up, Li Mo's mother was called to school the next day, and Li Mo was severely "forced" by her mother's stick that night.

Li Mo dug out the biology textbook in the bookcase, took a deep breath, and decided to get double points first.

Chapter 1 Entering the Cell

Section 1 From biosphere to cells

Life activities are inseparable from cells......

Last semester, he could only read the biology textbook as a bible. When did it become so vivid?

Movement and decomposition of Paramecium...Withdrawal reflex....

Li Mo was completely immersed in the textbook. This was the first time he discovered that learning knowledge was so interesting.

All living things are composed of cells one by one. Cells have such complex structures...

It's really interesting that cells in the human body have such complex structures.

"Bang bang bang" someone knocked on the door, and he jumped out of the textbook.

Li Mo's father stood at the door holding a new pair of sneakers. Without saying a word, he just handed the shoes to Li Mo.

Dad had just gotten off work. Li Mo looked at the alarm clock and saw that it was already 8:30 pm.

Last week, Li Mo's sneakers were torn. He clamored for his mother to buy him a new pair, but he was scolded by his mother. She always felt that playing basketball delayed Li Mo's studies.

Li Mo's father didn't say a word at the time, but he didn't expect that he would buy Li Mo a new pair of sneakers.

Li Mo looked at his brand-new sneakers and then at the time on the alarm clock, his eyes a little moist.

He calmed down and sat at the desk again. He knew why he wanted to study.

Sugar in cells...Inorganic substances in cells...Genetic information...Transmembrane transport of substances...Enzymes that reduce the activation energy of chemical reactions...Flow mosaic model of biological membranes...Reduce the activation of chemical reactions

Energy enzymes...the energy "currency" of the cell...the main source of ATP...

Unconsciously, he had finished reading a book, and Li Mo still felt that he was still unfinished. Why didn't he find reading so interesting before? If he had known that reading was so interesting, he wouldn't have had to be "forced" with a stick so many times.

Six hours later, Li Mo glanced at the alarm clock, which read 12 o'clock in the evening.

There was silence all around, and he came to the main hall again. Gray fog rolled in front of his eyes, and the gray figures on the high platform were still blurry.

Gray fog barrage:

Mission: Young man, stay up late and read at night

Completion: 100%

Reward: 10*2 subject points, one ordinary lottery

Barrage prompt: Do you want to conduct a lottery?

The lottery is going on! The gray fog is rolling in.

Lottery result: a cup of instant coffee

A can of drink rolled out of the gray fog, and Li Mo picked it up.

Brown can, no name, no production date, no manufacturer, no recipe list...

This is a complete product!

Gray fog barrage:

Product name: Instant coffee

Function: After drinking, you can maintain high concentration for 48 hours.

Tip: Even though coffee is good, it should be done in moderation

Li Mo was speechless for a while. Can a cup of coffee have such magical effects?

"Can I ask questions on the spot?" Li Mo held the coffee can in his hand.

Gray Shadow didn't respond, but at least he didn't object clearly.

One question and one answer is the most concise way of communication since ancient times. The person who asks the question has clear questions, and the person who answers the question has precise answers.

Countless questions were rolling through Li Mo's mind. He wanted to ask the Gray Shadow people why they kidnapped him, who was the Gray Shadow, what was this learning system, and what were the general laws of the universe's civilization?

But the Gray Shadow Man has already made it clear that he will only answer questions where the answer is "yes" or "no", which means that he can only use the elimination question method.

Li Mo thought about it and asked his own question: Am I useful to you?

"Yes", Gray Shadow's response was clear.

Only a useful person has the value of living. This dark law was learned by Li Mo from a novel. He always thought it was very reasonable.

Li Mo felt relieved. He knew that Hui Ying would not be disadvantageous to him for the time being. The next thing he had to do was to slowly find out Hui Ying's identity and purpose.

Gray fog barrage:

New task released

Mission: Everything is difficult at the beginning, upgrade your math to level one!

Explanation: Mathematics is a tool of knowledge and the source of other knowledge tools. All sciences that study order and measurement are related to mathematics. - Descartes

Reward: 50 subject points, one general draw, and one question and answer session.

Whether to accept?

"Accept", Li Mo didn't hesitate this time. He had already experienced the pleasure of learning, and he didn't know what the consequences would be if he didn't accept the task.

The gray fog dissipated, and everything in the room was as usual, except for the coffee can in his hand.

Li Mo felt that the coffee can in his hand was extremely hot.

He looked at the alarm clock next to him. It was exactly 12 o'clock. Sure enough, there was no time passing in the gray fog.

Sitting at the desk, he took out a notebook and wrote on it:

1. According to the "General Principles of Universal Civilization Law", the Gray Shadow can hide from me, but cannot lie.
To be continued...
