In his past life, Ryan, heir of the Silver Moon Clan, trusted the spy Oliver, and his whole clan was slaughtered by the Blood Moon forces, while the Dark Night Wolf King Cedric died saving him. Reborn on the eve of the massacre, he exposes Oliver, tames the mutant giant wolf, bonds with Cedric, and crushes the Blood Moon Clan's schemes. At last, they awaken the Silver Moon Halo to purify blood poison, slay High Priest Kaelen, unify the seven clans, marry, and welcome peace and love.
