[Upon attempting the River Transform to Dragon, a Celestial Thunder Tribulation will descend.
The might of this tribulation is divided into nine ranks based on the Tribulation Crosser's talent and bloodline.
The highest of the nine ranks is called the Nine Dragon Profound Thunder.
If one can pass this profound thunder tribulation, their dao foundation will be fortified, their bloodline purified, and their chances of becoming a dragon in the future will greatly increase.
Legend has it that for those who safely pass the Nine Dragon Profound Thunder, the heavens will bestow the Dragon Thunder Liquid.
This liquid is condensed from the confluence of the Dragon Race's Qi Fortune and the profound mysteries of the Great Dao.
Should a Cultivator obtain it, they can undergo Bone Marrow Cleansing, improve their Root Bone, and extend their lifespan by five hundred years.
Should a mortal drink it, they can prolong their life, adding fifty years to their time.]
