The Secret Emperor

Zayne Zhang, a servant disciple, hides his Sovereign Realm strength under Qi Condensation. When the Demon Sect attacks, he secretly protects the sect and helps Sylvia Sullivan awaken her Sacred Body of Extreme Yin. He transforms into the masked Sovereign and defeats the four Demon Emperors and their Ancestor Emperor. He then ventures into the Myriad Demon Abyss to slay the ultimate villain, helping the human race reclaim their Celestial Dao legacy and start a new era with Sylvia Sullivan.
