Fuguang, a vegetarian girl from a dilapidated sect, was forced to marry Lin Yuan Chongxi, the best swordsman in the immortal world, who was said to have lost all his cultivation due to being obsessed with evil and was not long dead, in order to seek a chance for survival. The outside world ridiculed her as cannon fodder that could not turn into a phoenix even if she flew on a branch. Her husband's family regarded her as a useless decoration. On their wedding night, she discovered that this sickly man was not as simple as the rumors, but a beast dormant in the abyss, waiting for opportunities to move.
The two began as a contracted couple who tested each other and were wary of each other. They were forced to join forces in a desperate situation with family strife inside and enemies outside. Fuguang relies on the ancient talisman technique that has been forgotten by the world to stabilize Linyuan's soul and break the curse. She shows amazing abilities in crises time and time again, overturning everyone's contempt for her. Linyuan, with the help of Fuguang, regained his strength step by step, killed all enemies and returned to the top. In this marriage that started out of calculation, they gradually discovered that each other was their only salvation and the destination of their hearts. In the end, the two of them worked together to uncover the shocking conspiracy that led to the dethronement of Linyuan and the destruction of Fuguang Sect. Together, they climbed to the top of the immortal path and became the couple of gods that everyone revered.
