Also known as I Became My Own Substitute
After transmigrating, Hai Xingchen gets bound to a Deep-Sea Aquaculture System. To complete her mission of opening an aquarium and extending her lifespan, she follows her boss's instructions and uses a sob story and her beauty to pretend to be an ancient Yinglong. She completes her first mission: subdue and bind the S-rank great monster Wen Yao Yu, making him submit.
For her second mission, she must save Shen Yuan, a wealthy heiress with no family, and help her inherit her estate, thereby finding a rich sponsor through a heroic rescue.
Just as her career takes off and becomes increasingly successful, Hai Xingchen accidentally discovers that her stunning, silver-haired, handsome boss Feng Xiangxi might not be human!
She even suspects that he's a demon beast hiding among mortals, planning to use a person of destiny bound to the System and then eat her before ascending!
Hai Xingchen doesn't want to die! So she uses the System's energy to seal Feng Xiangxi's powers. But by the time she realizes this is Wen Yao Yu's revenge for seeing through her lies, it's already too late!
Feng Xiangxi, who once led the charge and laid waste to the world, has become a sickly marquis. Wen Yao Yu is gravely wounded, and Hai Xingchen staggers away, all three of them badly hurt. Just then, the evil Fire Demon emerges, and Hai Xingchen draws her sword and looks around in bewilderment...
What? She's the only one strong enough to fight the Fire Demon!
No, no, no! She can't do it!
A bandit drifter and gang leader, a sickly marquis, and a sweet-faced college student with clear eyes join forces to hunt down the Fire Demon, beginning a new chapter in the love-hate saga between old enemies.
No wonder they look like someone from the past. They're the child of an old acquaintance!
