Phantom Blade Zero: how to solve the forest’s three-mirror puzzle
Listen for crying; the source’s directions depend on the starting orientation.

The mirror forest presents a left, forward and right choice. The Gamersky guide points first to writing on a tree: “循泣而行”, a clue to follow the sound of crying.
From the starting orientation shown in the source, choose left, forward, then right. Each correct choice transports you to the starting point for the next stage; there are three separate choices.
A new path appears after the third. If the directions do not match, check your orientation and the sound before repeating the sequence. The source does not establish whether solutions vary randomly or by version.
The source does not state its tested platform or version. Patch 1.0302256 does not identify this route; we have not tested it after the update.
