Song Zai traveled to the western fantasy land of Ireland and became a down-and-out baron on the frontier. The original owner's magic power was exhausted and he was exiled by his family. He was also accidentally bound to the "Love Strategy and Salvation System". The system informs the world that the core magic circle is out of balance and will completely collapse in 90 days. The key to repair lies in the hands of the empire's chief magister, Alicia, a cold and powerful person known as the "Frost Rose". The first task of the main line is to gain 50 favorability points from her.
As a magic loser, Song Cai relied on the system's information gap and mission rewards, starting from identifying rare magical plants, and gradually created "accidental" display value, and struggled to break into Alicia's field of vision. The unorthodox magic he exchanged with the system has aroused the vigilance and hostility of the Holy Light Church, which maintains the old order. On one side is the Inquisition's pressing and malicious stigma, and on the other side is the death countdown to the collapse of the world. Song Cai has to lie and perform to deal with the arrogant magister, the hostile church and the eyeing nobles.
Every time Alicia's favorability level increases, his risk of exposure increases dramatically. This started from the closeness of utilization and mission, and quietly deteriorated through life and death. When Alicia discovers that this seemingly fragile man who can always create miracles hides a secret that subverts her cognition, the collapse of trust and the survival of the world come at the same time. Song Zai can only risk everything, including this unspoken feeling, to uncover the truth behind the order and complete this impossible mission of saving the world.
