In the thirty-seventh year of the First Emperor's reign, purple energy from the sand dunes came to the world. Ying Zheng, who was about to die, was alienated and reborn. Everything the purple energy touched turned into strange shapes. Everyone thought it was a miracle. Only the alchemist Xu Fu knew that this was the harvest of civilization by predators in the star sea. The purple air is the spores, the spiritual energy is the bait, and the practitioners are all fruits waiting to be slaughtered. Ying Zheng realized the truth and actually used the fused spores on his body as bait to lure predators to Mount Tai, hoping to sacrifice the whole country of Qin to die together. Xu Fu mastered the oxygen species that the ancestors exchanged for self-destruction-oxygen, which is the natural enemy of purple energy and the iron curtain of human safety. After the Battle of Mount Tai, he carried the oxygen seed and hunkered down for thousands of years, only to see the spiritual tide resurrect in later generations, and humans tore open the protective shield with their own hands. When predators come again, Xu Fu, the thousand-year defender, steps forward and uses oxygen as a flame to protect the last vitality of human civilization.
