In another GT timeline. After Sun Wukong left the earth, Sun Wufan became the leader of the earth. Now that Sun Wuhan is old and about to reach the end of his life, he thought he would go to heaven after death.

In addition, there was Beerus, the God of Destruction who threatened to destroy the earth if the Super Saiyan God was not found. Faced with so many enemies, Sun Wuhan will never allow them to harm his relatives and friends. This time, it is up to him to save the earth!
