Wally's protection would last a week. Yet, Krune only took three days to finish the fusion and transformation of his Elemental and Chaos Meridians into ten Godly Energy Meridians. The process was a lot smoother than he thought, which significantly increased his confidence.
Another good thing was that after the meridians fused, each of the Chaos Meridians properties was enhanced after the fusion with the Elemental ones. As mentioned before, each Chaos Meridians could improve according to the laws of each Heavenly Property that the owner had comprehended.
For example, the Yin Chaos Meridian could absorb the laws related to Yin, like water laws and death laws. Now that it fused with one of the Elemental Meridians, its improvement because of the laws got even better. Krune could tell that his laws comprehension speed, which was already high due to the Godly Energy, got even faster.
