Quick Transmigration: The Sickly Cannon Fodder Keeps Himself Alive Through Studying

Gu Yu, the Gu family's genius heir and CEO of the Gu Group in City A, was a legendary figure. He died at the scene of a car accident. He never imagined that he would be reborn in the womb as a baby and lose his memories. He did not recover them until he was sixteen. It turned out that before he transmigrated into a book, he had accidentally bonded with a System and needed to study hard (?) to stay alive.

First world: The frail young master destined to be cannon fodder

Gu Yu: I heard I'm a terrible student?

System: That's right.

Gu Yu: And I'm cannon fodder, too?

System: Exactly!

Gu Yu: I've only got three months left, huh?

System (guiltily): Y-yes, but Host can extend your life by studying.

Gu Yu (forced by his cannon-fodder aura to become a terrible student, literally): ...

After a while, Gu Yu gave up struggling and spent his last three months doing nothing.

Gu Yu: I'm done.

System: ...

Second world: The master whose bones are ground to dust

Gu Yu: System... do you think I have even a one-in-a-million chance of surviving in this world?

System: No.

Gu Yu: Dropping it. Next.

System: ...

Third world: The movie star whose reputation is ruined

Gu Yu: I can't act.

System (looking at his results in the first two worlds): ...

Fourth world: The real young master who was abandoned

Gu Yu: Couldn't you treat me a little better?

System: Next time, definitely.
