Once an ordinary Magical Artifact reaches a certain level, it will transform into an Immortal Artifact. But this transformation isn't so simple. The Artifact Spirit within must also undergo a tribulation, and the Three-Colored Thunder Tribulation is precisely the kind of trial an Artifact Spirit faces.
Qing Ruo'ai nodded and said, "That's right. Later, it seems that Great Power was struck dead directly by that Thunder Tribulation. The coffin was then found by the Great Power's servants, who guarded it, and that's how the modern Immortal Coffin Sect came to be."
Wen Qingye nodded. 'If that person was killed by the Thunder Tribulation, then that means the Immortal Coffin's Artifact Spirit likely survived. It must have successfully become an Immortal Artifact. After all these years, its cultivation level must have stabilized.'
'An Immortal Artifact?' Wen Qingye couldn't help but feel a stir of interest. 'Having an Immortal Artifact would be an incredible trump card.'
