Reborn Drone, Who Says Technology Is Inferior to Cultivating Immortals?

Wang Ling traveled through time, but there seemed to be some problems while traveling. He was trapped in a dark place for millions of years, with nothing but a "Loading..." System interface.

What's worse is that after understanding it, he found that this is a world of immortality that is constantly declining.
