The Cultivation System Collapsed: I Became Its Puppet

By a stroke of luck, an utterly unremarkable office worker acquires a strange cultivation System.

"Ding! Kill him. Don't hesitate."

"Ding! Hesitate, and you'll lose."

"Ding! How dare you disobey me!?"

His younger sister stares at her brother in horror. The relative who was once so gentle is now trying to kill her.

"Sis... I'm sorry…"

As the blade falls, his sister's head rolls to a stop at his feet.

"Ding! Congratulations! How does it feel to kill your own flesh and blood, my little demon king?"

Wang Rui thought that getting a System would let him ascend to the immortal realm and become a carefree god. Instead, the System drags him deeper and deeper into the abyss.

His hands are stained with the blood of his own family, and the only goodness in his heart is slowly disappearing.

The Heavenly Court once tried to poison him to death, but the immortal sent to carry out the deed was poisoned and killed by Wang Rui instead.

The Buddha Tathagata of the Western Paradise tried to reform him, but Tathagata was struck by a catastrophe.

This demonic System is gradually turning him into a puppet that knows nothing but killing.
