Outside the Three Realms, the ancient Demon Lord has been sealed in the Abyss of Annihilation for thousands of years. The sealed place was infiltrated by the Demon Lord's aura, and a fairy grass containing the spiritual energy of heaven and earth grew up. This grass matures once every thousand years, and when it blooms, it can temporarily weaken the seal, and the Demon Lord uses it to absorb external spiritual energy to maintain his spiritual consciousness. In order to strengthen the seal, the fairy world regularly sends fairies to take care of it to ensure that the fairy grass grows pure. However, in this life, the fairy grass will give birth to an independent spiritual consciousness, and its birth will subtly shake the balance of the seal, starting a cycle of cause and effect that affects the fate of the three worlds.
