When modern-day Wang Qinglv transmigrates into the Gu world, she chooses a path where rules restrain the strong and protect the weak.
At the beginning of her transmigration, she gains an Immortal Gu as her companion, and at six years old, she attracts the Eternal Gu. But her most powerful Gu is the law in her heart.
In this Gu world, where the strong prey on the weak and might makes right, she wields the Law Path like a sword. She begins by establishing "family rules" for a clan, then sets down "trade laws" for merchant caravans, and eventually drafts a "constitution" for the righteous path of the world. She firmly believes that rules are not shackles, but armor for the weak and a form of self-discipline for the strong.
She meets her most terrifying opponent, who seeks absolute freedom, while she safeguards rules for all. Their ideals clash, leading to an ultimate showdown, and in the depths of the Sea of Rules, they reach an astonishing understanding.
When she discovers that the laws of Heaven are flawed and the Sea of Rules is on the verge of collapse, she makes her final choice.
"Rules are not meant to restrain people, but to let everyone live with dignity."
