The Hell Emperor Returns as a Silent Father

The legendary Hell Emperor vanishes from the immortal realms only to reappear in the mortal world—as a devoted single father. Bound by a vow of silence, he protects his family from shadows they can't see. When mysterious benefactors emerge and old enemies resurface, his father-in-law grows suspicious: who would help them without reason? As supernatural threats close in, this once-mighty ruler must balance fatherhood with his hidden past, all while keeping his true identity secret.
