Who Stole My Manhole Cover?

What does it mean to step on the wrong foot and fall into this different world where rituals are broken and music is broken? Not only is it unsystematic and invincible, but every step it takes is difficult. The only thing that protects itself is the brain of modern people and... A manhole cover? This other world is really full of malice! Gu Yan could only survive by pretending to be Chu Moxuan, the aristocratic son who accidentally fell off a cliff. Every step of his plan is on thin ice. Can he protect himself and the people he wants to protect? Accumulation is for a stronger explosion next time... Aura, ether, martial arts, demons, demons, dragons and immortals. Even if he is cursed sevenfold by the devil, targeted, and stabbed in the back... I will definitely survive, definitely!
