The Demon Lord Became the Leader of the Righteous Path by Laying Low

Blurb:

The demoness Jiang Chenbi is reborn just as the righteous factions are selecting a new leader of the Mystic Order. She eagerly signs up, hoping to infiltrate the enemy's upper ranks and bring down the Mystic Alliance from within.

What she never expected was that her new body would have such a terrible reputation. Word on the street is that she can clear her name and win the election only by completing one of the following tasks:

1. Capture every notorious fugitive in the top one hundred of the Mystic Order's most-wanted list.

2. Refine an unparalleled immortal pill that can grant even ordinary people eternal life.

3. Follow in the footsteps of the ancient Emperor of Shangyu, leading humanity to defeat the demons and unify all four races.

4. Single-handedly kill a great demon on the same level as the Demon Lord Jiang Chenbi.

Jiang Chenbi: Easy. Why don't I just kill myself?

Killing herself is out of the question. Jiang Chenbi says, "Actually, there's another way. I can just keep my head down and outlast everyone with more seniority and prestige than me. Then the position of Mystic Order leader will be mine, won't it?"

Years later, Jiang Chenbi's junior is interviewed. His eyes are full of world-weary sorrow as he sighs:

"All I can say is, I regret it so much. Sigh... I used to think she meant she'd outlast them with time. Then I found out she meant she'd cook them in a big pot."

Content warnings:

1. The male and female leads have a bad ending. Don't read if that's not for you.

2. The story is plot-focused, and the male lead has very little screen time.

3. The female lead has somewhat questionable morals.

Theme: Abandoning the self and searching for the self.
