Yun Wuya transmigrated to another world and awakened an Emotion System. Whenever someone envied him, resented him, or hated him, he could collect emotion points and exchange them for items in the System Shop.
The items Yun Wuya could exchange for were certainly powerful, but they all came with a few side effects!
Braised pork that made you hop wherever you went, Qi-Blood Fruits that inflicted the pain of being struck by a sledgehammer...
A chance attack unexpectedly led Yun Wuya to discover a new way to use the System's wares.
Years later, looking back on that chance attack, Yun Wuya couldn't help but sigh: “The side effects of the System's wares are just wonderful!”
