Half a month later.
At the entrance of the alchemy hut, Chen Mu lay in a rocking chair, holding the sword box gourd in his hands, his attention completely absorbed by the changes within the gourd.
In his mana perception, various materials had fused into a new substance within the sword box.
These new materials formed into tiny, invisible grains, accumulating bit by bit in some predetermined structure.
They slowly grew into a palm-length, flat, date seed-shaped thin blade, as if they were alive.
Its surface was a cinnabar red, with some feather patterns.
Chen Mu watched in amazement, "No wonder it's called Zhu Yu, the magic sword looks like a peculiar cinnabar feather."
Within those special structures lay intricate True Meaning Talismans. It was these that endowed the magic artifact with mystical divine skills such as flying escape and piercing armor.
Compared to that, the Wood Spirit Boy he had previously refined was as crude as a little toy.
