In order to prevent being killed by Steve, he decided to escape from the Central Island. Unexpectedly, he was accidentally involved in the turbulence of time and space and entered the Ultra Universe. The protagonist starts out as an ordinary ender dragon, then evolves by swallowing it, and eventually becomes an execution dragon or even a higher being.
