After I Transmigrated Into a Book, I Made Everyone Cry

Transmigrated into a book as a cannon-fodder female supporting character? As a top student at the Federation's best military academy, Chi Ning, the ultimate grind machine, isn't scared in the slightest.

Assigned to the bottom-ranked engineering department? I'll grind my way into the combat department.

Awakened with the lowest F-rank ability? I'll grind my mental power higher.

I'm done grinding, I'm really out of steam...

Hehe, just kidding. I'll even grind my way to a better family background.

The whole school is at its wits' end. Sis, please stop grinding already!
