The ancient Heavenly Emperor Jun and Queen Xihe fell in the Lich Catastrophe. Their souls went through thousands of years of reincarnation and were reincarnated during the period of the Three Sovereigns and Five Emperors of the human race. As "outsider wise men", the two assisted the sages of the human race, guided the human race from ignorance to civilization, and witnessed the complete process of the human race from being protected to self-reliance and self-reliance.
