Evolve from a Pile of Bones

Nie Yuan traveled through time and became a pile of withered bones in the underworld. Little by little, the little bones swallowed up all the power they could and slowly grew. Until one day, a large undead summoning array summoned Nie Yuan to the outside world. "It turns out the world outside is so wonderful!" "I will work hard to evolve and open the passage between the underworld and the outside world!" "I want to be the only king in heaven and on earth, the Holy King of the Dead!" Let's see how the little skeleton counterattacks the gods and dominates the world... This novel and its characters are purely fictitious.
