Good Grief, the Immortal Emperor Was Reborn a Version Early

Immortal Emperor Ye Lingtian was reborn, but unfortunately, he was reborn a little too early. The spiritual energy of the Blue Star had yet to recover. Immortals had not yet descended, demons had not yet run rampant, and even his wife had not been born. To continue the love he shared with her in his previous life, he had no choice but to quietly build up his strength while protecting his future father-in-law before he could come into his own. What? An old man living inside a ring? You audacious evil spirit, daring to show off your meager skills before this Emperor! You fell off a cliff and received power from a reclusive master? You beast, trying to possess someone, are you? This Emperor will destroy your soul right now! Ye Lingtian: Don't worry, Father-in-law. As long as I'm here, I won't let anyone hurt you. Ye Lingtian's father-in-law: Could someone please remove this fool who's rewriting the plot?
