[Campus-like story + counterattack of the top student + growing male protagonist + multiple cycles + single female protagonist]

On the day of the 100-day oath-taking ceremony, the poor student Fang Lisu got stuck in a time loop.

Whatever happens on this day will be reset on the next day.

Only his experience and ability will be retained.

Others keep repeating this day,

He has unlimited time and unprecedented life experience:

[You memorize the vocabulary list 300 times, unlock the ability: <Thesaurus Decoding>]

[You solve 5000 math problems and get the achievement: [Prince of Mathematics]]

[You do 20,000 push-ups and develop a physique: [Perfect chest muscles]]

During that period of growth that no one knew about, he created infinite possibilities! ~
