Wang Chen placed the Green Sun Crown upon his hair bun.
This Green Sun Crown was an inferior Magical Treasure, primarily designed for Divine Soul defense and protection, meaning its main function was to defend against enemy Divine Sense attacks, with secondary functionality against Spell attacks.
Cultivators above the Golden Core Realm could gather and condense their Divine Sense to strike at their opponent's Divine Soul, an attack that was formless, intangible, and difficult to defend against.
Even if one's Divine Soul was very strong, it could hardly withstand frequent and numerous Divine Sense attacks!
This was where the Green Sun Crown came into play; it could automatically protect its wearer and guard against enemy's surprise attacks.
Including Spell attacks.
Moreover, after putting on the Green Sun Crown, Wang Chen clearly felt his mind become more lucid.
Without a doubt, this was a very practical Magical Treasure.
