Su Yu transmigrated and suddenly obtained a synthesis bar. All things in the world can be synthesized! No matter what it is, in Su Yu's hands, it can become a rare treasure! In Su Yu's hands, as long as there are enough items, even a kitchen knife can become a dragon-slaying sword. Ordinary white paper synthesized into the Primordial Golden Scroll. Ordinary clothes synthesized into ethereal immortal clothes. Ordinary Qi and Blood Pills synthesized into Nine-turn Golden Pills. Any item, under the synthesis bar, can become a treasure that countless people covet!
