Demi-human Girls Completion Manual - Chapter 47 - 44

To pass as an imperial concubine, one must be professional.

Actually, the profession of an imperial concubine is pretty good. The emperor will accompany you in eating and drinking, and even pay you for it. What’s not good about that?

She, a renowned assassin of the 21st century, actually crossed over to become Su Manor’s most useless good-for-nothing Fourth Miss.

He, Jin Empire’s imperial highness, was an emotionless overbearing demonic tyrant with unrivaled talent.

Everyone knew that she was idiotic and good-for-nothing and bullied her as they pleased. But only he, the overbearing tyrant with the discerning eye, wouldn’t let go of her even if his life depended on it.

For the time being, let’s just see how the stubborn versus stubborn clash and play out in this good show of the chaser and the chased.

As a successful villainous BOSS, in addition to having ideas and aspirations, one must also keep in mind three points:First, grow sneakily, don't act rashly (once a villain acts rashly, they basically won't survive past three chapters).Second, you're not a good person, so be ruthless (becoming more evil will make you three times stronger, while redemption weakens you by seven times).Third, remember the two points above. The moment you forget them, your end is probably on its way.
