Kill Me More Times, I'll Become Invincible - Chapter 75:

When Li Fan transmigrated into a new world, his life seemed unremarkable. He was moderately well-off, with a wife and children, but nothing extraordinary. Everything changed upon his death, when he awakened the ability Return to Truth: the power to virtualize an entire lifetime’s worth of experiences, run it as a simulation, and return to the age of twenty armed with that knowledge.With this ability in hand, Li Fan finally saw a chance to pursue the dream he had always harbored: eternal life. In other words, the path of immortal cultivation.But the world of cultivation was nothing like the paradise he imagined. After countless generations of cultivators plundering heaven and earth, the heavens had struck back. Mortals now carried the Immortal-Mortal Miasma within their blood, a disease that, when encountered by cultivators, led to cultivation decline and death.

That morning, she had made it clear that it was just a one-night stand and nothing more. He would treat it exactly that way and carry out his responsibilities.Protagonist has System---No NTRIt's Harem, with many girls but The Singer is Main Heroine.

The course of commitments never did run smooth.

Just became the disciple with the highest seniority, but the Age of the Dark Mist descended, and the sect plummeted into a land plagued with raging demons.

Shen Changge who had already written his suicide note suddenly awakened to a Check-in System.

[Check-in at Training Ground, Success, acquired: Cultivation Base*50 years]

In the Age of the Dark Mist, demons were rampant, and an impenetrable mist veiled the empyrean. By vanquishing demons, the mist could be dispelled, and new check-in locations could be unlocked. By doing so clandestinely, Shen Changge became a Sword Saint.

When a demon broke into the Empyrean Sword Sect, everyone in the sect was powerless. People were in despair, until they met that young man in white who had just checked in at the Empyrean Peak. The young man’s eyes were ablaze.
