This Red Cloud in the Prehistoric Times Is Not Simple

What should I do if I come to prehistoric times and become a red cloud? To give a futon or not to give a futon? What should I do if I come to the wilderness and become Hongyun who has given up the futon? Is it to change the cause and effect, or to commit suicide? What if you come to Hongyun and become a futon, and at the same time Donghuangtai and Dijun are ambushing Hongyun, waiting to enter the network? To die or not?
