After studying the Sage's memories for a month, Zhang Ming let out a long, weary breath.
He had more or less figured out the basic principles behind how the Pillar of Heaven hunted Demon Gods.
To put it in human scientific terms, the Space-Time Worm was an immensely powerful Demon God, but it had yet to hatch and possessed only some passive defensive abilities.
The Blue Crystal Civilization had a thousand years to slowly accumulate targeted "last wishes."
The Blue Crystal People's "last wishes" were something profoundly mind-driven, formed from their strongest obsession at the instant before death. This obsession would transform the crystal on their forehead into a supernatural strange object capable of "granting wishes."
Of course, this so-called "wish granting" was hardly omnipotent.
For instance, if someone's last wish was "to make everyone in the world happy," such a vague, sweeping wish could not be fulfilled.
But if their last wish was "to give anyone who touches this crystal a feeling of happiness," a simple wish like that could be fulfilled.
Moreover, the stronger a Blue Crystal person was, the more functional and versatile the last wish they left behind upon death would be.
The one Zhang Ming had fought, for example, could even exchange a few simple words-though, of course, that was merely an obsession.
The entire population was divided into five ranks: Ding, Shi, Neng, Xian, and Sage. These ranks were determined by the value of their last wishes after death.

According to the memory fragments, a Sage was someone who had broken through the three bottlenecks
