I read a novel and forgot its name. There is a protagonist named Ruomu, a woman named Sang (who can summon magical butterflies), and others named Horseshoe and Horsetail.

There are five passwords in The Classic of Mountains and Seas, and Ruomu only appears in the first and second volumes. The hero is (Ruomu's younger brother) and You (his apprentice), and the heroine is Luo Ling (an unbreakable wife, a successor in her heart). If Wood belongs to the royal family of the Great Xia, it is a direct biography, and it is likely to be on an equal footing with Xia Jie. The woman surnamed Sang is called Sangguxiu and has a crush on Ruomu.
