[Overpowered from the Start + System + Sign-In Progression + Invincible + Passionate + One Female Lead + Yandere]

In this vast starry sky, nine mysterious Coiling Dragon Pillars tethered a mysterious immortal coffin as it drifted aimlessly through the cosmos.

Inside the coffin lay a young man of extraordinary origins, his soul already extinguished.

Qin Guan, an ordinary young man from Blue Star, accidentally slipped and fell into a small river in a park at night. To his astonishment, he transmigrated into the body of the young man buried inside the immortal coffin.

Then, as the coffin lid was lifted, Qin Guan saw the light of day again, and the sign-in System arrived with it.
