Lu Ji, a lowly live-in son-in-law, lives a wretched life.
He marries into the Liu family and is treated with nothing but contempt and abuse. His beloved wife, Liu Zhiyu, is forced by her family to marry a rich heir instead, and eventually dies by suicide after suffering domestic violence. Lu Ji scrapes by on his own until he suddenly dies in a dim, run-down rental room.
A fragment of his soul drifts into the Heavenly Secrets Continent. He endures a thousand years of hardship and cultivates to the pinnacle of the Tribulation Transcendence stage, only to be ambushed by a trusted follower and an old enemy working together. His tribulation fails, and his soul is scattered.
When he opens his eyes again, he finds himself reborn to the time shortly after his wedding to Liu Zhiyu.
In this life, Lu Ji returns with immortal arts passed down through the ages and resumes his path of cultivation in the modern city. He crushes every person who once oppressed him, from spiteful relatives and arrogant rich heirs to martial arts grandmasters and criminal gangs.
No one knows that this despised, useless son-in-law is actually an Immortal Emperor who once swept through countless worlds. This time, he will defy fate, protect his wife for the rest of her life, and conquer the entire city!
