With her wrist injury unhealed and seeking the pulse-renewing dew, Xie Qinghe brings a broken old sword into the Buried Sword Secret Realm. Borrowing the ancient sword "Huizhi", she discovers that after breaking through the barrier by borrowing the sword, she must still personally receive moves and return it to its original seat before leaving the realm. She travels alongside Lu Wensheng, whose eyes are injured and who identifies paths by listening to swords, to search for the third inner pivot. Yan Wufeng, impatient to seize the inheritance, forcibly opens the joint trial, causing the sword formation to spin out of control. Xie Qinghe stops copying the moves of others, ultimately passes the sword-returning trial, and brings back the spiritual medicine. Returning to the sect, she recovers from her injuries and retrains, passing the inner sect supplementary exam with her broken old sword, realizing that the Way of the Sword lies not in seeking speed, but in judgment, holding back, and bearing responsibility.
