Episode 21 recap: Mo Chenyuan and Mo Haoli perished together.

Feng Ruoyao received the Xuanming Order in the Qingxu Realm and knew that something must have happened in the Xuanming Realm. She hurriedly returned with Mo Chenyuan and found the Demon Realm in ruins. All the disciples of the Xuanming Realm had been killed, and even Feng Ruoyao's assistant, Wuyou, had met an untimely death. Seeing everything before her, Feng Ruoyao gritted her teeth in anger. She vowed to tear apart the one who destroyed the Xuanming Realm and killed the disciples.

At that moment, laughter echoed from the position of the Demon Lord. Mo Haoli had completely succumbed to darkness and ascended to the throne of the Demon Lord. Mo Chenyuan never expected that by severing their Immortal roots, they would turn into demons. Mo Haoli declared that dealing with Mo Chenyuan was not just a matter of cultivation. Nangong Xinlan mocked Feng Ruoyao, saying that her disciples were weak and easily wiped out by her.

Fueled by her hatred for her enemy, Feng Ruoyao immediately flew forward and engaged in battle with Nangong Xinlan. Mo Haoli left his throne and headed straight for Mo Chenyuan. Nangong Xinlan was the first to be defeated, while Mo Haoli managed to restrain Feng Ruoyao. He knew that Mo Chenyuan's Rotating Heaven Lock was of little concern, so he brazenly attempted to strangle Feng Ruoyao.

Mo Chenyuan trapped him in a formation, but Mo Haoli, in order to absorb energy, extended his demonic claws towards Nangong Xinlan, sucking away her energy until she was depleted. Mo Haoli then burst out of the formation. In order to save Feng Ruoyao, Mo Chenyuan chose to perish together with Mo Haoli. Feng Ruoyao pleaded with him not to do so, but Mo Chenyuan only wanted to ensure her safety. Mo Haoli and Mo Chenyuan dissipated like smoke, leaving Feng Ruoyao in intense grief. Suddenly, she thought of her Crimson Flame Feather and exerted all her efforts to infuse it with energy, believing that one day she would reunite with Mo Chenyuan.
