"Crossing the second Heavenly Tribulation is something that happens after reaching level 100. As for raising the innate attribute of root bone to forty points, it's a goal that we don't know when it can be achieved, and it's completely unpredictable."

Although it was only a difference of five points in root bone innate attributes, the difficulty of improvement was even greater than crossing the second Heavenly Tribulation. One at least had a clear path for cultivation, but the progress of innate attributes was elusive and no one understood.
Even the refining time in Ancestor Hall had a certain probability, which could be targeted for specific tasks.
