[Mission System] + [Invincible Male Protagonist] + [Foreshadowing Reversal] + [Counter Routine] + [Decisive Killing]
A good-for-nothing monk with dirty spiritual roots, and an unknown immortal who escaped from prison:
The two met that night because of the system;
From then on, under the possession of the immortal, the useless monk improved his skills day by day and became the best immortal cultivator in the world...
That's weird!
What does it mean that the immortal takes away the monk's body, but becomes the spirit behind it?
Is this the other way around?
…
Burning cities, escaped criminals; ferocious demon kings, empty heavenly soldiers; gradually declining sects, and the secrets about cause and effect hidden in all clues;
Chaebol, Cyber City; Immortal Cultivation Sect, Reincarnation - the vast world will be changed by the encounter between these two people;
A journey of cultivating immortality in the near future is about to begin!
But before that:
"What do you mean the system wants me to work for free for this immortal?"
The road is long;
When will the sky rise?
