Jing Yuan left suddenly, and Ya Nan hurriedly took over the soul ship and joined the Forgotten River to cross the soul. On the way to interpretation, she encountered many strange souls and struggled to find out through trial and error. As he gained more experience in soul crossing, Yanan discovered that there was a mysterious dark soul power behind his obsession with the soul. Spiritual practitioner Yun Shu told him that this is an evil force originating from the depths of the underworld and can devour the origin of the soul.
In order to explore the truth and save Jing Yuan, Yanan formed a team with Yun Shu, Xuan Feng and others. They went deep into the soul prison, experienced many crises such as the storm of resentful souls and illusions, and finally revealed the shocking secret: Jing Yuan fought against the dark soul forces alone in order to protect Ya Nan; and Ya Nan was actually a "soul-suppressing saint" with pure soul-suppressing bloodline.
A war related to the safety of the underworld is about to break out. Can Ya Nan resolve the crisis and protect the peace of his soul?
