After Zhou Yu set up the array barrier on the island,
he sat cross-legged.
He began to restore his primordial power.
While recovering, the Divine Soul Firebird soared out from Zhou Yu's palm, surrounding a black shield, continuously spewing fire.
This black shield was a magic treasure refined by Zhou Yu using crystal chips left from the wings of a Black Butterfly.
The defense of those Black Butterfly wings was so strong that even Zhou Yu was quite shocked.
Therefore, using crystal chips to craft a defense magical treasure, its power can be imagined.
Defense magical treasures, compared to attack treasures, are much easier to refine.
The most important thing for defense magical treasures is the defensive materials themselves.
As long as there are good defensive materials, they can be quickly refined.
The remaining time is actually spent on properly nurturing it.
