Qi Deviation (走火入魔)

In xianxia, qi deviation is the same concept English calls "qi deviation" or "qigong deviation", but the common overseas misreading is to treat it as "magic damage" or "training backfires badly". In practice it is bound to three conditions — forcing a breakthrough, practising an incompatible method, or a temperament that cannot carry the power — and its bodily signs (blood, ruptured meridians, mental disturbance) are the result of the cultivator falling out of alignment with the order of the universe.

The Korean subtitle community has openly documented that even professional subtitle writers sometimes give up on translating qi deviation and related niche xianxia terms cleanly, because the character limit of subtitle presentation simply does not allow enough room to unpack the system-level meaning. The recommended handling from the English-language fan community is to keep the term romanized on first use and add the "system misalignment" idea in one line.

Watch this scene together with tribulation scenes and you will notice the grammar difference: qi deviation is accidental or forced by internal imbalance; tribulation is structural and comes from outside. Both signal danger, but the source of the danger is opposite. A writer who mixes them up is writing lazily.

Evidence level: A (first-hand evidence from Korean subtitle practice) + B (specific xianxia-context confusion texts are thin). Related entry: heavenly tribulation.
