Journey to the West: I, the Bull Demon King, Slay Guanyin from the Start

Lu Yu, a modern man, unexpectedly transmigrates into the Bull Demon King and obtains a check-in System. He quietly checks in for fifteen hundred years, keeping his head down until the era of Journey to the West. From the start, he finds Red Boy being bullied by Guanyin. How could he stand for that?

First, he destroys Guanyin, then kills Medicine Buddha, a quasi-sage who comes to her aid, severely wounds a clone of the Tathagata, and captures Tang Sanzang and his disciples alive.

With a rallying cry, he summons the demons to his side, storms the Heavenly Palace, and breaks through Mount Ling. I am the peerless Demon King, the Bull Demon King!
