Transmigration into a book + system + space + food hoarding + strong female lead + face-slapping + the female lead is neither a saint nor brainless (believe me!)

A top assassin transmigrates into a book and becomes cannon fodder who gives the female lead a cheat ability?

As a big shot, can he tolerate this?

No!

She couldn't bear it!

He got the cheat code and destroyed the female lead.

Living a carefree life in the apocalypse.

She also managed to snag the male supporting character she had her eye on.

Inability to provide a brief introduction

Consumption Guide:

1. A woman favors a man.

2. The female lead is not a saint.

3. Will criticize the original female lead

4. Before the female lead transmigrated into the book, the male supporting character and the original owner of the body only had a brother-sister relationship; the male supporting character only liked the powerful figure after transmigrating into the book. (This is important.)
