In his previous life, he was Niu Dali, an ordinary man crushed beneath life’s burdens, struggling to survive like an ant in a forest of steel and concrete. With no home and no rest, he was trapped in the mire of fate, unable to escape. One long sleep transmigrates him to a wondrous world that merges Investiture of the Gods with Journey to the West, where he becomes the mighty Bull Demon King, famed throughout the demon realm...
After awakening, he inherits the Bull Demon King’s powerful bloodline and supernatural abilities. His horns curve like the crescent moon, his body looms like a mountain, and his strength can shake heaven and earth. He masters the Seventy-Two Transformations and domineering staff techniques, and commands the Cloud-Cave of Mount Jilei, shaking the demon world with his might.
As the Great Sage Who Pacifies Heaven, he becomes sworn brothers with the Great Sage Equal to Heaven, Sun Wukong, and rules over a domain of demons with bold, untamed swagger.
I only read a little bit before I dared not continue. It's a good book, but it made me uncomfortable; it was more painful than reading about the Bull Demon King in Journey to the West.
