Others who traveled through time were either god kings or demon kings. I was still delivering food after my rebirth - but the style of my delivery list was a bit wrong.
The first order of system activation: within ten minutes, deliver the "Abyss BBQ" to the cave lord. If it times out, a nuclear bomb will be triggered to clean the land. From then on, my eDonkey traveled all over the forbidden areas of mortals: delivering "life-extending elixirs" to martial arts masters in exchange for secrets that he had collected for hundreds of years; delivering "awakening milk tea" to the glamorous goddess, and uncovering alien spies lurking around her.
When the battlefield of all races came and the night watchmen guarded the cracks, I silently accepted the order to be sent to the "Headquarters of the Gods" - a note of requirements: keep away from strangers, and stay away from gods.
