Reincarnated as Jiang Yan, the Underworld Nether Emperor, who possesses supreme divine might, he was judged to have the lowest E-class divine gift during the talent awakening ceremony, becoming the laughingstock of the entire audience and suffering cold glances and mockery from everyone around him. Yet prejudice can never trap a true powerhouse; he quietly breakthrough to the first rank of martial artist, suddenly summoning the Ten Yama Courts that shake the heavens and earth. Just as alien races launch a massive invasion and myriad realms' forces arrive successively, Jiang Yan holds up his accompanying ancient umbrella, pulls out the sharp blade deeply hidden within, and transforms into a fierce ghost sword immortal. He commands the Ten Yama Courts to gallop across the battlefield, invincible with a single ghost sword, and wherever the sword's edge reaches, gods and demons are all beheaded on the spot.
