Who Traveled Through Time in a Coffin!

What is it like to travel through time and become a groom? Yagyu's response was: Who is a good person who traveled through time and put himself in a coffin? Relying on the corpse control skills he learned from his predecessor, Yagyu even accidentally refined his 'wife' into his own Taoist corpse, becoming a true 'half-baked corpse chaser'. But he soon discovered that the dying posture in his memory, the mysterious bronze door space in his mind, and the strange murals inside the door all pointed to a huge mystery. Where does the path of cultivation in this world lead in the end? Is this time-travel forced on him a coincidence, or... A premeditated and precise calculation?
