Advancing to the Innate Realm was truly a succession of difficulties and an escalation of dangers,
Braving the severe risks of impotence, paralysis, or sudden death, it was with great difficulty that the 53 aperture points of the governor and conception vessels were unblocked, only to find a massive pitfall awaiting at the end.
The governor and conception vessels govern the Yin and Yang of the human body, but both are cut off at the upper palate and the root of the tongue.
To completely connect them, the tongue must press against the upper palate, acting as a bridge for the two vessels, commonly known as "Building the Golden Bridge."
This step sounds simple, but it entails great risks when executed.
It requires Inner Breath to be simultaneously infused into all aperture points of the governor and conception vessels, using combined force from both the upper and lower body to breakthrough.
This means—the entire spine and brain are covered in it!
