Why can't martial artists step into the Marrow Cleansing Realm before the age of fifty, and if they can't, they never will, even if they were as powerful as Hua Yunsheng, the number one on the Wind Cloud List, who mastered the Five Elements Domain and whose Martial Arts will was incredibly strong? The reason lies in the loss of vital essence and energy from the body before achieving an 'Immaculate Body.'
Even if it is possible to somewhat compensate by strengthening the inner world through the refinement of the Five Viscera and Six Viscera, the loss is ultimately still a loss.
Those experts in the Six Viscera Realm who are in their sixties or seventies might still look as young as those in their thirties like Meng Danyun, and their Yuan Gang power might not appear significantly diminished. Yet essentially, their vital essence has significantly diverged, no longer vigorous, turning sluggish from active, which isn't apparent from the surface but represents an internal deficit.
