From Teahouse Keeper to Immortal

When the Willow Cup Teahouse is raided, Li Yao watches her foster mother die and finds a poison mark hidden inside a failed healing pill. She already studies broken pills for a living, but now every ruined batch in her shelves starts feeling like evidence. A boy she trained in secret vanishes with a bamboo blowpipe, and the man she once called father tells her the life she believed was built on a lie. Yao is left with tea stains, a dead woman, and a name she can no longer trust. She turns her grief into a plan, learns what the fighter clans fear most, and starts hunting the people who made her into a tool. The one who taught her everything may be the one who used her first.
