Stop Calling Me the Savior. I'm Really the World-Destroying Villain

[Lighthearted comedy + powerful and satisfying heroine + villainess + System] Ye Hehe transmigrates into the body of the eldest princess of the tiny kingdom of Qihuan. Ding! The Host's reckless, death-seeking behavior has successfully activated the “World-Destroying Villain System”! The goal of this System is to cultivate the ultimate world-destroying villain! The Host must complete the ultimate mission: “leave all living things devastated and the land filled with suffering”! Ye Hehe is thrilled. An irredeemably evil villainess? This is going to be fun! Awakening with a useless body that has no spiritual roots from the start? No problem! She can't use the spirit pills herself, so she'll give them all to the good-for-nothing spirit guards in the military camp, fatten them up, then seize their cultivation! The alchemy pavilion's venerable master throws his weight around thanks to the Ethereal Sect? She'll rob them of every spirit pill, hang up a corpse as a warning, and make an example of them! The Ethereal Sect has exploited Jing for a hundred years? She'll overturn the rules and make the men of Jing stand tall! She lashes the spirit guards, raids the alchemy pavilion, and takes on the venerable masters. Acting like a maniac, all she wants is to throw the world into chaos and meet her world-destroying KPI as soon as possible! But she never expected The spirit guards she trained to the brink of death see her as a goddess who saved them and swear to follow her to the end; The opponents whose cultivation she plundered cry and beg to be “disciplined” by her again; Even the mysterious priest from the Sacred Altar regards her as the only hope of breaking the deadlock and worships her with fervor! Ye Hehe: ??? The hidden truth: The so-called transmigration golden finger is nothing more than the dying fantasy of someone on the verge of death. The World-Destroying Villain System: the heroine's serious illness, diagnosed in the real world. The Sacred Pavilion: the body's highest command center, the brain. Completing the world-destroying mission: giving up the will to survive, allowing AI cells to run rampant and break through the body's defenses until the body dies. The immortal golden finger: “willpower.” No one is impossible to kill; only willpower cannot be killed. The System's reward, returning to the real world: a final rally before death.
