The Seven Noxious Divine Yin Pill was actually not a poisonous item. It only contained an extremely cold Yin energy that was very oppressive. If a person with lacking a cultivation base swallowed it, it could cause the person's meridians to break, crippling one's cultivation base.
Seeing Yi Yun hold the Seven Noxious Divine Yin Pill, the mouths of the Thousand Hand Granny and Shentu Nantian twitched. However, they did not believe that Yi Yun would be able to identify the pill. This was because this pill was extremely valuable. It was a secret concoction made by the Shentu family clan. A junior like Yi Yun would never have come into contact with it.
Yi Yun played with the pill. Just holding it made Yi Yun feel the cold biting into his body.
Yi Yun could still clearly remember the feeling of the frost Qi entering his bone marrow from two months ago.
