From the start, Li An transmigrates to a cultivation world and gets a little System. Its main task is: endure the flames of karmic fire ninety-nine times, then be killed to ascend.
At last, she reaches the required number of times. The price is that everyone in the world reviles her, and the five Venerables join forces to attack her. She thinks she can finally get the death she seeks, but the ruler of the Demon Realm produces an ancient divine artifact: a scale.
The past is finally laid bare in its entirety. The world is stunned: she was actually the savior of this realm...
Theme: The protagonist is neither wholly righteous nor wholly evil, decisive and ruthless, and takes the world as a game. She takes on the flames of karmic fire to fulfill the System's task, yet uses dark methods along the way to protect the entire world.
