732 Top Tier Mortal Killer Move

Hu Immortal blessed land, Dang Hun palace.

Fang Yuan was sitting cross-legged on a cushion, looking at a pair of bat wings in front of him with full concentration.

A pair of large bat wings was hovering in front of him, thin and small scales of an eerie blue color with each having the size of a pinkie finger grew on the wings. As light refracted from the scales, it seemed to be giving off starlight.

After Fang Yuan returned from Lang Ya blessed land, he started repairing the star demon bat's wings. After nine days and nine nights of effort, it had reached the current crucial moment.

"Whether I can fix these bat wings or not depends on this." Fang Yuan willed and summoned a mortal Gu from his aperture.

He flicked his finger and threw this crucial mortal Gu in.

The mortal Gu turned into a drop of jade green liquid which created a layer of green light when it shot into the bat wings.
