I fabricated myths to guide the revival of spiritual energy.

Gu Qing is dying. To survive, he must convince the world that "spiritual energy has revived." No spiritual energy? I'll create it with special effects! No cultivation techniques? I'll write them in code! No relics? I'll bury and dig them up on the spot!
But he never expected that as he continued to fabricate stories, the world would truly become strange. Scientists went mad looking at the runes under their microscopes; the Western Church worshipped sword immortals who arrived from the East on clouds; the Book of Life and Death in the underworld became the most coveted secret for the world's richest; and even on the far side of the moon, monsters that wanted to devour the Earth actually crawled out.
Watching the Earth cultivators, who had been completely fooled and were now charging towards the alien fleet with great fanfare, Gu Qing helplessly drew his sword: "Since I have taken your trust, I will naturally have to bear the consequences if the sky falls."
This is a legend that began with fraud and ended in myth.
