I Got an Inheritance from the Start, and Bureau 749 Set Its Sights on Me

Mysterious revival + reborn in the modern city + invincible + no harem + the underworld + Yama

After returning to his hometown, Zuo Yan took a nap. When he woke up, there was inexplicably something inside his body. It said it was the will of the earthly way, gave him a Seal of the Yin Son of Heaven, and told him to rebuild the underworld.

Zuo Yan: “In that case, all the demons and monsters of this world, are you ready? The underworld's gods of darkness are already standing by.”

Zuo Yan: “City Gods, the Ten Great Yin Marshals, Ox-Head and Horse-Face, Judges, Meng Po, and the Ten Yama Kings, get back to your posts at once!”

Zuo Yan later learned that the reason the world's spiritual energy had dried up was the Investiture of the Gods battle. Tongtian fought the Four Sages and shattered the heavens and earth, reshaping the forces of fire, water, and wind. The interference of an unknown outsider also contributed to the spiritual energy's decline.

He later learned that both the Heavenly Dao and the Human Dao had tried to restore the golden age of the primordial world, but both had failed. Now, with this final opportunity, everything would begin with rebuilding the earthly way and the underworld.
