Su Han once suppressed all his enemies as the Great Emperor of the Human Race. After spending countless years in another world, he has reached old age, his body is failing, and his lifespan is nearly exhausted. Meanwhile, the Abyss has been invading Earth for three years. Dragon Nation's No. 7 Shelter is running out of energy, and its defensive perimeter continues to shrink.

The elderly couple take the call records to the command center to plead for help, where technicians confirm an abnormal reverse spatial fluctuation. Lei Zhen decides to use the energy reserved for just one single-person passage to bring Su Han home.
