The supreme ruler of the demonic path, lord of ten thousand demons, has blood on both hands and a fearsome reputation.
One day, he is forced to bind himself to a Merit Cultivation System.
Fail to accumulate merit, and his soul will be scattered.
Thus, an unprecedented spectacle appears in the cultivation world: the Demon Lord Shen Mo "washes" the Alchemy Sect in blood, when in truth he is rooting out the scourge of those selling inferior pills;
he "slaughters" an ancient great demon, all to stop it from destroying the world. His merits are immeasurable, yet his karmic burden is immense.
He saves the world, yet people see him as its greatest calamity.
When the apocalyptic disaster descends, he faces it alone amid the curses of all living beings, while crimson karmic flames consume the heavens behind him. "If saving the world means bearing the infamy of thousands, then I, Shen Mo, will be the demon to the very end!"
