Trial use

The inheritance does not name which Gu he must refine. He has three choices, each of which would refine a new Gu, and he watches a hairy man begin a refinement, then distracts that hairy man until the attempt fails. Fang Yuan collects the materials afterward and moves on without finishing a refinement from that bundle. ^{ch. 357}
