"The talisman core serves as the magic array, the altar, the door lock, and fundamentally determines whether a talisman can communicate with the universe and activate its spiritual Qi. Only by activating the talisman core will the talisman be effective. Without the talisman core securing the magic spell's divine power, the talisman can't be carried around and preserved. Once written, the magic immediately takes effect.
Therefore, the strength of a talisman, how long it can be preserved, and how long it remains active heavily depends on the talisman core. This step is a closely guarded secret that each sect does not share.
As for the talisman ends, they wrap up the whole process by finalizing the talisman and serving as a conduit through which cultivators channel their spiritual breath to activate the talisman core. Different talisman cores require different methods of infusing the talisman ends with spiritual breath, and these methods are also secrets.
