A possible concise summary is:
Xuan Ji, Ling Long and Min Yan, three young cultivators from Shaoyang Sect, encounter their old friend Si Feng from Lize Palace while hunting a demon bird. However, Si Feng acts cold and distant towards them, and reveals that he wears a Loveless Mask that suppresses his emotions. Xuan Ji tries to cheer him up and remind him of their past promises, but Si Feng rejects her and leaves with his companions Ruo Yu and Lu Yan Ran. Xuan Ji is hurt and confused by his change, and wonders if he hates her for not contacting him for four years. Meanwhile, the Sky Hall, a secret organization of demons, plots to obtain the spirit keys from the Five Great Sects and unleash the God of War and the Star of Mosha. Wu Tong, a former human who betrayed his sect, leads the operation and manipulates the demon birds to attack the cultivators. Si Feng tracks down the demon's lair and injures it, but also exhausts himself. Xuan Ji stays with him and tries to heal him, while the others go after the demon. Si Feng tells Xuan Ji that he doesn't care about her or the Mirror of Origin anymore, and that he has grown up and changed. Xuan Ji refuses to accept his words and insists that they are still friends.
