The First Prohibition envelops the whole body; it is the foundation.
After this, the Second to the Eighth Prohibitions gradually strengthen one of the four limbs and five viscera. They are specifically the sinews, veins, skin, flesh, bone, both arms, and both legs.
The Ninth Prohibition is the Soul and Spirit, thoroughly completing a minor stage and acquiring the first Divine Skill 'Solid White' of the Taibai Luminous Godly Ban!
An Jing's choice for the Second Prohibition was naturally his arms.
The wrist and palm of the Golden-haired Bear were particularly well-suited for this purpose; aside from their toughness, they allowed An Jing to unleash many times the strength in his arms when he activated the Magic Prohibition.
Thus, when An Jing burst forth, he could exceed his own limits by a significant margin by utilizing the Imperial Heaven Method and Taibai Divine Prohibition!
