When Ivan was studying the legends of other worlds on the continent of Iseland, he was accidentally involved in the dispute between the other world and the spiritual world. He was chosen to be the guardian and shouldered the important task of maintaining the balance between the two worlds. Under the guidance of the Stone of Wisdom, Alvin embarks on a challenging adventure.
He first explored the other world, learned magic, established contact with the guardians of the elements, and communicated with various creatures in the misty forest, gradually understanding the secrets of the other world. Under the guidance of the gatekeeper, Ivan discovered the time vine that connects the other world and the spiritual world, and learned his true mission as a guardian.
