Eleven Reborn, I Protect Forty-Two

Class 7 of Senior Year, 53 students, 11 of them returned with memories of the future.

They remember every exam and every ranking next year. But none of them can remember who stood at the front of this classroom in their previous lives.

On the first day of school, Wen Liang tore up a student's test paper. Not because of cheating, but because he had not seen that method for solving the problem until his second year of graduate school.

All 53 students' papers showed the same method used by 11 of them. Even the extra minus sign was in the same place, at the upper right of the same letter.

He had a red pen in his pocket. When he circled a name, three lines of text appeared on the page:

[Shao Lidong · Class 7, Senior Year · Student No. 41]

[Original trajectory: 2026.6.7, did not make it out of the exam hall]

[Current deviation: 0%]

He circled the names one by one. Eleven names, all with the same date. Later, he circled all 53 students. It was still that same day.

Those 11 had returned with memories from after that day. The other 42 knew nothing.

And they remember everything about the future, but not a single memory includes this homeroom teacher.

The pen can only observe, not change anything, and its ink dwindles with every use. There are 279 days left until that day.

He decides to get every one of these 53 students out of the exam hall alive.
