"Among the twelve meridians, there are four types: Hand Taiyin Meridian, Hand Taiyang Meridian, Spleen Meridian of Foot, and Three Yin Meridians of the Foot, corresponding to the martial artist's arms and legs.
Once these are connected, the corresponding arms and legs will undoubtedly experience a significant increase in strength.
For instance, if the three meridians of the Hand Taiyin Meridian are opened, then the strength of my left hand will soar, and when inner strength flows into it, there won't be much consumption, allowing the full power of the inner strength to be unleashed.
The same applies to opening the Spleen Meridian of Foot.
Having all twelve meridians connected will let the arms and legs exert formidable power, and even withstand martial artists' weapons with bare hands. Techniques like palm and fist methods will subsequently become extremely effective."
