Ling Yun was ridiculed by the disciples of the Immortal Sect because of his "pseudo spiritual roots". Although Su Muxue was a talented swordsman, she was ostracized due to family grudges. The two accidentally formed a team during the Qingyun Sect's entry trial and were forced to face the dangerous "Secret Realm of the Fallen Demon" together.
During the trial, Ling Yun accidentally awakened the hidden "Chaos Sword Heart", which can swallow the demonic energy in the secret realm and convert it into spiritual power; with the help of Ling Yun, Su Muxue broke through the shackles of the family's secret technique and understood the "Ice Heart Sword Mind".
Just when the two were about to pass the trial, they discovered that there was a conspiracy behind the trial - the elders actually wanted to use the blood essence of the trial disciples to feed the ancient monsters in the secret realm.
Ling Yun used the Chaos Sword Heart to resist the attacks of monsters, and Su Muxue used the Ice Heart Sword Mind to cut off the chains of conspiracy. The two teamed up to expose the elder's crimes. Not only did they successfully pass the trial, but they also became the new generation guardian of the Qingyun Sect, starting a new journey of cultivating immortality together.
