In Grade 12, What the Hell Is a Succubus Training System?

When Cheng Che was in the last 100 days of his third year of high school, he bound to a "Succubus Development System."

[Stamina 48: gets out of breath after taking two steps; an embarrassment to the succubus race]

[Endurance 43: has to rest three times while running 800 meters; the worst of the worst]

[Charm 47: even the Demon King would want to remove your household registration]

[Intelligence 51: what’s the difference between you and a slime?]

[Overall evaluation: the worst of the worst, trash among trash, a hundred-year-rare disgrace to the succubus race.]

Seeing this, Cheng was furious!

So Cheng... began following the system’s tasks and started growing.

The daily task list looks like this:

Run five kilometers (stamina +1, endurance +1)

Study seriously for five hours (intelligence +1)

Skin care + go to bed early (charm +1)

...Wait, wasn’t this supposed to be succubus development? How did it turn into a high schooler’s ascetic training?

But this is only the beginning.

Step by step, Cheng Che rises from a low-grade succubus, to a lower succubus, and then to the throne of the Succubus King!
