The rolling magma condensed its shape, and the flames from the center of the earth forged its soul. He woke up from the chaos, inherited the demon god's will, shouldered the mighty power of the sky, and vowed to use his power to level the world! This is the Bull Demon King - the real master of the Eight Hundred Miles Flame Mountain in Hezhou, Xiniu, a hero destined to stir up troubles in the Three Realms. He was once the "Great Sage of Pingtian" who made a blood alliance on the Huaguo Mountain. He was sworn in with the Monkey King and other seven brothers. He was so heroic that he wanted to compete with God. He was once a demon giant who dominated one area. He had the Cuiyun Mountain and the Jilei Mountain, a beautiful wife and concubines, and thousands of demon soldiers under his command. His reputation was enough to make the gods and Buddhas look at him. However, the wheel of fate rolled over ruthlessly. The brothers turned against each other, Buddhism and Taoism spread eastward, and a grand plan centered on "Tang Monk's Buddhist scriptures" pushed his carefully managed hegemony to the forefront. When his beloved son Hong Haier was subdued by Guanyin, when his sworn brother Sun Wukong waved his stick at each other in order to find the path to enlightenment, the huge forces of heaven and Buddhism quietly surrounded... This once arrogant demon king was forced to face the most tragic years in his life. Behind the three-tone banana fan's game of wisdom and courage, and the shocking battle with the gods and Buddhas, is the cruel collision between personal love and hatred and the current of the times. This book tells not only the history of his powerful and vigorous conquests, but also the difficult choices and inner struggles of a generation of heroes caught in the cracks of fate. See how he awakens from his obsession with power, reflects on his dominance and family ties in a desperate situation, and finally completes his tragic transformation from "Pingtian Great Sage" to "Mighty King". This is not only a legend of the devil, but also an ancient elegy about ambition, obsession and letting go.
