Invite Taoist Friends to Enter the Flags

Personally, I feel that there are three development directions for novels like this. The first one is that the magical weapon transforms into something similar to acquired beings. The first is that the environment does not allow this type of transformation, which is similar to acquired gods evolving by rules, but you obviously can't achieve it. Otherwise, yours is not a fairy weapon, but a divine weapon. The second one is to become a plane similar to the cave world and the dark side of hell. The third one is to directly become a weapon.
