Even if this might spend 90% of his vitality, he was going to extract those three Origin Beads. He did not believe that he wouldn't be able to find the fish in a dried pond.
Following Mo Wuji's decision to suck away the vitality within himself and his World Channel, his skin started to wither.
Mo Wuji's Undying World was formed from his World Channel and his World Channel was one of his 108 meridians. Thus, the life force from within the Undying World was also being sucked away. At the same time, the energy which formed the world was also being extracted. Even if Mo Wuji was any more capable, he was unable to do this without losing his vital blood.
His skin withered, his vital blood evaporated, and his bones turned grey…
No matter what happened, Mo Wuji maintained his clarity. He definitely wasn't going to faint.
