The senior brother of Qingyan Sect always believed that his junior sister loved helping the world and saving people, so she ought to cultivate the Dao of All Beings.
The spirit of the First Thought Sword always believed that its master was innocent and clueless, and probably hadn't decided which Dao to cultivate yet.
The young master of Lingxu Pavilion always believed that if the little rabbit could casually refine top-grade pills, she ought to cultivate the Pill Dao.
The second prince of the demon race always believed that the annoying girl was a heaven-sent genius at swordplay, so she ought to cultivate the Sword Dao.
The Miaojiang Saint always believed that Brother Ye Zhi was willful and spent his days at play, so he ought to cultivate the Dao of Freedom.
At first, the Demon Venerable believed that his junior sister cared for others as she saved them, so she ought to cultivate the Dao of All Life. Later, after seeing Helan Ruo flirt her way around, he decided she ought to cultivate the Dao of Love.
In the end...
Senior Brother/Sword Spirit/Young Pavilion Master/Second Prince/Saint/Demon Venerable: "What Dao did you say you cultivate? The Heartless Dao?!"
Helan Ruo: "I think so."
I don't know either! Master said that having affection for all things in the world is what makes one truly heartless!
Everyone's darling, a harem of regretful pursuers, multiple secret identities, one woman with multiple partners, and a ship-war story. The first few dozen chapters lay the groundwork for which Dao she should cultivate, so the pace is relatively slow.
The female protagonist's character is somewhat hollow; the story might be written from a third-person perspective rather than the female protagonist's.
Meow meow meow, it's quite good, but there's a slight feeling of helplessness. The junior sister is quite lively, and her character design is quite likable. If she cried all the time, I'd think she was the kind of soft, spoiled, crybaby wife, but that kind of plot doesn't happen. It's still quite fun. I don't want her to actually become a soft, spoiled, crybaby wife later on.
