In the land of Kyushu, spiritual veins nourish all things like blood vessels. However, due to the competition between the great powers thousands of years ago for the "ancient spiritual contract", the spiritual veins were broken and the spiritual energy was exhausted. A hundred years ago, the "Sword Bone Tribe" was falsely accused of being the culprit of spiritual vein depletion, and the entire clan was massacred. Only the young master Ling Yun survived with the "Sword Bone Curse" (the sword bone will devour the host's vitality as his cultivation level increases) and hid in a border town.
In an accident, Ling Yun awakened the "Eye of the Spiritual Contract" in his golden finger, which allowed him to see the broken spiritual veins and communicate with the remaining "spiritual spirits". In order to clear his family's grievances and repair the spiritual veins of Kyushu, he embarked on a journey: on the way, he met Su Qingyuan, the "genius of spiritual planting" who was rejected by his teacher, and Mo Chen, the "puppet master" who guarded the ancient ruins. The three teamed up to find the "spiritual contract fragments" scattered in Kyushu.
However, the mastermind behind the scenes, the "Xuanxu Sect", has already laid a trap - they attempt to seize the spiritual contract fragments and use the spiritual energy of all the nine states to refine the "Immortal Pill" to make the sect elders immortal. Ling Yun must not only fight against the Xuanxu Sect's pursuit, but also suppress the deteriorating sword bone curse in his body, and face the cruel prophecy that "repairing the spiritual veins requires sacrificing the blood of the sword bone clan." In the end, he used the "Spiritual Contract Eye" to fuse all the fragments, used his sword heart to reshape the rules of the spiritual veins, broke the curse and prophecy, brought Kyushu back to life, and rectified the name of the Sword Bone Clan.
