Chapter Five, The Secret Room.

As Yu Jing prepared to get up and check on the situation of others, a strong sense of drowsiness swept over his body while he was standing.

However, the situation is different from what Yu Jing imagined about the ventilation ducts. Inside the hollow walls, there are no ventilation openings. Instead, there is a deep and straight passage that cannot be seen to the end. The darkness inside limits the visual distance to five meters, and even if Yu Jing brings a desk lamp, he can only see a distance of twenty meters at most, still unable to see the end.

Yu Jing directly put his hands in his pockets, wearing a hat to cover half of his face, maintaining this posture and sitting still in his seat.

Now we need to find a hard object to smash open the wall and see if there is a ventilation duct inside.

Although Yu Jing analyzed it this way in her mind, in actual practice, she still used the method of filling the hollow iron clothes hanger in the bathroom with solid objects to increase the overall strength, slowly prying out the iron nails on the wooden board.

Yu Jing is more adapted to this kind of silent environment where everyone suspects each other, because he usually spends a lot of time in such an environment in high school. Students who share the same dormitory with Yu Jing and have bad character often make him fall into even worse situations because of some habits that he cannot tolerate.

From the hall to the study, then to the bedroom, and finally to the sink under the bathroom sink, when Yu Jing knocked on it with two fingers, a hollow sound came from the inside of the bathroom wall, indicating that there might be a ventilation duct inside the wall that could be used to escape.

On the eve of the college entrance examination, Yu Jing usually goes to bed after midnight and wakes up at six in the morning for early reading. His mental state throughout the day remains good. But today, it's only eight o'clock in the evening, and he feels inexplicably tired.

After three consecutive strong strikes, Yu Jing's hands, whose physical fitness was not very good, felt a bit weak. Finally, he managed to knock open a big hole in the not-so-thick cement wall.

Something is not right.

This is the only exit from this locked room and my only chance to leave. Perhaps this research experiment is similar to an "Escape Room" game. I have already met all the requirements, and now I only need to overcome my fear of the dark and successfully navigate through here to pass the test. Once I receive the 3.5 million yuan test bonus, I can pay for my mother's surgery in full.

How could ... ...

Beng, Beng, Beng!

Yujing doesn't know why, but there is some concern in his heart for a girl named "Yu Xiaoxiao". Because in Yujing's eyes, Yu Xiaoxiao's body seems relatively slender compared to others.
