The Jade Ruyi.
The fourth-rank Spiritual Treasure once held by the previous Qingxuan.
In truth, this Spiritual Treasure possessed no Thunder Transformation Tribulation Avoidance properties!
However, given its nature as a fourth-rank Spiritual Treasure, even if wielded by a Crystallization Realm Master relying solely on its Artifact Spirit, the effect it produced would still be far superior to most of this world's third-rank Thunder Transformation treasures!
If a Crystallization Realm Master could use the Jade Ruyi as their Thunder Transformation treasure, their chances of surviving the Golden Core Thunder Tribulation would increase by a large margin!
In fact, if not for the rules of the Celestial Dao, which dictate that a cultivator must personally endure a portion of the Thunder Tribulation's power, then having the protection of a fourth-rank Spiritual Treasure would be a practically guaranteed pass through the Golden Core Thunder Tribulation!
