Back in the Divine Realm, the Void Bug siblings — born of the same mother — were the guardians of space elements, with the brother striving diligently and ultimately becoming the God of Space Elements. You should know, the Seven Great Elemental Gods are all Level One gods, equivalent to what we call Super God-level powerhouses now. And being in the Divine Realm, a god with godhood isn't quite the same as a wild god rank.
Meanwhile, Little Lazy Bug was especially lazy, seemingly having given all its diligence to her brother, spending all day just sleeping. The Dragon God controlled the nine elements, which naturally included the space element. She just ran over to the Dragon God and absorbed the space elements from him to sleep. Yes, not to cultivate, but to sleep. Because by the side of the Dragon God, it didn't have to consciously absorb any energy to replenish itself; sleeping was sufficient.
