As the last trace of mana was injected into the Li Fire Furnace, delicate strands of mana circuit traces appeared on the surface of the Celestial Azure Cloud Tunic.
In these days, through Zhang Yu's repeated refinement, the material quality of the Celestial Azure Cloud Tunic continually improved, and its internal mana circuits became increasingly complex and sophisticated.
The quality of this magic treasure has also been elevated to the level of Level 7.
Not only has the distance of the Celestial Azure Sand it can release increased from the original ten meters to dozens of meters, but the speed, scale, and precision of its ejection have greatly improved.
While initially it could only supply 10 Formless Warriors, now it can steadily support 20 or more Formless Warriors.
And Zhang Yu's craftsmanship in producing the Celestial Azure Cloud Tunic had reached the level of Level 10 a few days ago.
