Yin Sha Evil Spirit.

Yin Sha refers to the innate spirit—Yin Sha Demon Spirit, while Evil Spirit refers to the Heaven and Earth Spiritual Treasure born by merging into the Innate Yin Sha Demon Spirit.
This object is present in the memory of the Fake Pill Demon Soul, but previous cultivators did not discover its role in Heterodox Core Formation, whether Evil Cultivator or Demon Cultivator, they only considered it as an auxiliary item to enhance cultivation.
Of course, this is related to its absolute rarity, similar to East Spring River, it exists but its role is little known. As for the most fundamental reason, according to the memory of the Fake Pill Demon Soul, those who consume the Yin Sha Evil Spirit are eroded by its Yin Sha Demon Spirit, becoming a reincarnated shell of the Yin Sha Demon Spirit.
