"If that is the case, then let me, as the Green Envoy, illuminate you on the matter of the Thunder Tribulation…"
In Lady Xu's narrative, Chen Yuan gained new insights. In his original understanding, he knew that all the weapons in the world were divided into four levels.
Those were the levels he had previously mentioned: Mortal, Treasure, Spiritual, Divine.
Although the first three grades have distinctions of high and low, noble and common, when compared to Divine Weapons, they are still far inferior. Lady Xu said that whenever a Divine Weapon emerges in the world,
it must face the descent of Thunder Tribulation, because a Divine Weapon can no longer be considered a mere inanimate object, but is regarded as a kind of atypical living being.
Atypical beings must undergo the tempering of heavenly tribulation.
Succeed and it becomes a Divine Weapon; fail and it reverts to a mundane object.
