In an imaginary world full of fantasy, the male protagonist accidentally swallows the legendary "Sky-Swallowing Ball" that can give people supreme power, and has the ability to swallow all things since then.
The "Sky-Swallowing Ball" does not come from this world, but is a channel for invasion from higher dimensions, with the ultimate goal of swallowing the entire world. In order to prevent this catastrophe, he must make a choice: sacrifice himself and close the "Sky-Swallowing Ball" forever; or devour everything and become the supreme master.
