Journey to the West: I'm Sun Wukong, and I Get Stronger Every Time I Roast Someone

His soul travels back to the era of Journey to the West, and from the start, he becomes Sun Wukong!

He also awakens a System that lets him grow stronger by mouthing off to people. He starts by taking on his senior brother, then goes to pick a fight with Patriarch Bodhi.

Tathagata: "Why's this monkey got such a temper?"

Patriarch Bodhi: "I have no idea! He came right up and started cursing me!"

Tang Sanzang: "How come this cheeky monkey's even better at mouthing off than I am?"

From then on, this world has a new, defiant and unruly monkey.
