Since the creation of the world, there have been spirits in heaven and earth. Clear spirits are immortals, turbid spirits are demons, controlling spirits are gods, destroying spirits are demons, and ghosts are ghosts. But there is another clan, although it is small, but it is born special - the Eldar clan. Legend has it that if you have unfulfilled wishes before you die, you will summon spirits, gather the spirits into Su, and Su will fulfill your wishes. Using the Soul Soul Powder as a bet to summon spirits, if successful, the corresponding price is: you have to give him a ray of your soul. However, the legend has been too long ago and the memory is blurred. Gradually, people gave Su another name: Su Demon.
