Awakening the Twelve Ancestral Witches at the Beginning, You Call Me a Disaster

[No system], [Plot flow], [Not brainless], [Decisive killing, stable and crazy] Traveling to a world of high martial arts, Fang Xiu spent eighteen years as a starving ghost. He can never have enough energy and blood, and his appetite is comparable to that of a glutton. The whole school laughs at him as a human-shaped black hole. Until the day when Wuhun awakens... The twelve ancestral witch totems tore through the sky, and the awakening crystal exploded! The whole school was dead silent, and the principal trembled and exclaimed: "Martial... Martial God Body?! And there are... Twelve?!" Awakening is the peak? ! No, hunger has just begun. Fang Xiu discovered that every time the ancestral witch awakened, he had to swallow a huge amount of energy and blood. Others rely on talent for cultivation, but he relies on "eating" to become stronger. Wherever he went, resource prices skyrocketed, and low-level warriors wailed: "Disaster, he is a disaster!" When all the forces regarded him as an 'uncontrollable disaster', Fang Xiu smiled. He walked toward the battlefield of all races with a knife, and behind him, the shadows of the twelve ancestral witch spirits stood tall: "You said I defeated the human race?!" "Then I will eat up all the races in the world... And use their blood to support my ancestral witch!" "Remember——" "My name is Fang Xiu, and I will rest until death!"
