Free-spirited, flirtatious sword spirit X dark, obsessive, scheming merman
Qiu Yinzhu transmigrated into a book, becoming the sword spirit of the tragic, powerful villain.
The villain was named Ling Yugu. His life was just like his name: lonely and solitary.
He had once been a peerless prodigy, so far beyond everyone else that he could guard the land with a single person and a single sword. Everyone admired him.
Later, he sealed the Demon Abyss with his own strength. But after suppressing it for too long, he was instead corrupted by demonic energy. His family feared him, his elders dreaded him, and his friends kept their distance.
At last, just when he had managed to suppress the demonic energy and was at his weakest, they showed their true colors. They dug out his sword bone, stole his spiritual root, took his golden core, drained his bloodline... No one cared that he had spent three hundred years suppressing the Demon Abyss.
In the end, he stopped suppressing the demonic energy and willingly fell into demonic cultivation. He wanted to destroy the whole world, but the male and female leads joined forces and killed him.
As blades pierced his heart, he smiled with relief.
Qiu Yinzhu transmigrated into the book when he was at his lowest. She watched the boy lying on the bed, struggling to endure the demonic energy eating away at him, and formed her spiritual energy into a tentacle beside him.
For some reason, her spiritual energy had the power to purify. When the boy saw it, he was like a kitten encountering catnip, clutching it to his chest and unable to let go.
His furrowed brow relaxed, color returned to his pale lips, and even the demonic markings on his face disappeared.
Qiu Yinzhu: So well-behaved, so cute. I want to keep him!
From then on, if anyone bullied him, she protected him. If he wanted to kill someone, she did it for him. Whatever he had lost, she would help him take back.
She never expected him to reveal his true merman form just to lure her out. "Big sis, help me. I feel so uncomfortable..."
Qiu Yinzhu looked at the little scales slightly raised on his mermaid tail and swallowed. Shamelessly, she fell for his seduction.
When she finally brought him to the protagonist's group and helped him turn over a new leaf, she discovered that the ultimate big boss in the Demon Abyss was actually herself?!
Qiu Yinzhu: This can't be right?
1. Gender-bender, non-explicit. The training is meant to strengthen their relationship.
2. The male lead is only obedient in front of the female lead. They're both strong; he isn't delicate. He's weak early on, but will recover later.
3. The female and male leads have normal anatomy; they only use props.
4. Both are each other's only partner; happy ending.
