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 a low profile until the age of Journey to the West. From the start, he finds Red Boy being bullied by Guanyin. How can he let that stand?

First he wipes out Guanyin, then kills Medicine Buddha, a quasi-sage who arrives to provide support. He gravely wounds a manifestation of the Tathagata and captures Tang Monk and his disciples alive.

He raises his arms and countless demons answer his call. He storms the Heavenly Palace and lays siege to Spirit Mountain. I am the peerless Demon King, the Bull Demon King!
