Besides this, the womb is also called the "Extraordinary Fu Organ", similar in form to a fu (a hollow organ), but its function is akin to a zang (solid organ), storing Essence Qi without leaking.
The most crucial point is that during pregnancy, the womb is in a state of "Storing," sealing up Essence Qi to nurture the fetus.
During childbirth, it enters a state of "Releasing," delivering the fetus and consuming essence and blood.
Because of this, the womb possesses the power to shift between Yin and Yang, from death to life.

"Reverse!?" Zhang Fan's eyes sharpened, blurting it out.
"Correct. To go with the flow is to become human; to go against it is to become Immortal..." Wu Qingnang nodded.
