Oath of the Spiritual Key

Lin Mo, a seemingly ordinary kid from a wealthy family, is actually the heir to the Lin family's inheritance of immortality. Su Yuqing, a taciturn transfer student, has the mysterious power of a "spiritual girl" hidden in her body. Due to an unexpected encounter, the two were involved in a huge conspiracy involving the spiritual world and the human world. Faced with the pursuit of the "Shadow" organization, the secret of the spiritual key and the legend of the door to the spiritual world, they moved from campus to society, from ordinary to extraordinary. In the process of growth and adventure, Lin Mo gradually uncovered his family's mission, and Su Yuqing also awakened her own power. The two work together to fight against powerful enemies, find spiritual hearts, save each other, and finally embark on a path to immortality that changes their destiny.
