Kael Vorn was reborn to three minutes before the global cataclysm. In his past life, he was abandoned by his wealthy classmate and girlfriend, and died horribly in the jaws of a monster. In this life, he took the lead in swallowing the black mamba that was about to evolve into a dragon, seizing the calamity-rank Black Dragon bloodline. While others were still struggling to awaken their armor, he had already transformed into a dragon man, devouring and evolving, building his power and harvesting the Mutant Fruit. Facing the military's missile barrage, he only spread his dragon wings and sneered: "In my past life, the Black Dragon could even swallow nuclear bombs."
