Weak? I'm the Sealed God Heir!

Su Liuli hid what she was and married the immortal Wen Yong. A rival princess of the Demon Clan and the Demon Lord trapped her, and she died giving birth. The Demon Lord drove a soul-binding nail into the infant, Chase Lowe, sealing the divine bloodline he had inherited, and the princess raised him herself into the most notorious playboy in the realm. Nobody looking for the heir could find him, because the seal hid what he was too. Years on, the Demon Lord is close to waking from his own seal. Wen Tian, lord of the divine realm, has lost much of his power, and his only daughter is unremarkable. He announces a martial tournament in the lower world, framed as a contest to choose his daughter's husband, though what he is actually hunting is the next ruler of the Six Realms and any trace of Su Liuli's line. The Demon Clan sees the opening and moves on the divine realm's throne, and the war spreads across the six realms.
