It is something every disciple of the Shuiyue Sect must hold in high regard.
It is said that this token contains a secret and extraordinary immortal technique, discovered by the founder of the Shuiyue Sect purely by chance. He had hidden it within the token, intending for future generations of the sect to cultivate it.
However, no one expected the Shuiyue Sect to fall into such decline. By the time it reached Mei Changhai, the previous sect leader, it was already impossible to cultivate the technique within. Mei Changhai himself only possessed the cultivation of an Earth Immortal; let alone practicing it, he couldn't even grasp a single shred of the profound mysteries hidden within the token.
