Under the shadow of the modern city, Ao Chen, the successor of the dragon bloodline, and Feng Ling, the successor of the Phoenix bloodline, are forced to partner up due to the mission of the Spiritual Realm Management Bureau. The two have very different personalities and conflicting ideas, but in the process of fighting against the Taotie Order, which covets the origin of the mythical beast, they use the "Eye of Time" and "Nirvana Fire" to complement each other, and gradually develop trust and affection in the crisis of life and death. From getting along to becoming connected, they face the ghosts in the administration and the conspiracy of the cult, and awaken the ultimate form to turn the tide. Even after the war, their strength declined, but they persisted because of love and bond, working together to protect the balance of the spiritual world and each other, and writing an adventurous love song in which the inheritance of mythical beasts and the glory of humanity are intertwined.
