When practice this meridian to a certain level, you will be blessed and guarded by Yin, Soft and Tai Chi Internal Skills. If you have more internal skills and the skill level is higher, the effect will become much better.
This meridian is the low-level version of Yin Heel Vessel and its force is limited, so it is named as Hidden Meridian.
Unable to be activated along with Yin Heel Vessel.
