The D-arm survived the lightning baptism.
Ves knew how close it had been. Although the storm only struck 18 times, the power behind the bolts were at least partially scaled to the Bitter Scimitar's approximate power, quality and other parameters.
He understood a little more on how the lightning tribulations operated. They were never supposed to let off anyone or anything that broke the boundaries of cosmic ecosystem so easily.
The amount of rounds was probably determined by the severity of the supposed violations.
It was useful for Ves to know what to expect next time if he committed another 'violation' in the eyes of the heavenly authorities.
For example, anything that attempted a feat as bold as merging the 5 classical elements together would definitely attract the most severe 9-round multi-modal lightning tribulation!
The same went for a feat as bold as creating a god ship such as the Dominion of Man!
