As they attempt to arrest him, Ye Hong Yu from the Monastery of Knowledge and Obeisance, rescues him. Ning Que is miraculously admitted into Tang Academy.

The Third Elder sacrifices himself for the Empress and for the lives of the barbarians being slaughtered. Mo Shan Shan tries to get justice for the people killed in her group, but General Luo and Qu Ni hinder her efforts, forcing Ning Que to reveal his true identity.

While battling, Yan Se and Guang Ming attain Dao by breaking through all five of the levels. To exit the Main Gate of the Demon Sect, Ning Que, Shan Shan, and Hong Yu rely on Tang Xiao Tang, who agrees to lead them out if Ning Que promises to help her become a student of the Tang Academy. With the help of Lee Man Man, Ning Que convinces Shan Shan to go to Tang Academy with them.

The demon in Ning Que comes out, and the battle doesn’t end well, though it suddenly dawns on him that Sang Sang has been in his heart all along. He makes things clear with Shan Shan, then unexpectedly meets Fu Zi while drinking away his sorrows.

After Sang Sang used her Heavenly Luminescence to take down Xia Hou, her chilling disease relapsed with greater intensity. To help her, Fu Zi recommends Ning Que take her to see Qi Shan, who is the only person who can save her. Hong Yu defeats the Grand Priest of Justice to take over his position. In search of Ning Que, Long Qing finally finds him and exacts his revenge.
