Nearly two hundred years ago, a majority of parliament's members were actually selling useful intel of the Pinhian Republic to the other kingdoms. All this to increase their personal wealth and influence.
Using that information, those other kingdoms actually managed to trap three disciples of Vicious Lightning Paragon and killed them ruthlessly!
After finding this information and verifying it with someone trustworthy, the Vicious Lightning Paragon could no longer contain his fury.
He slaughtered all members of the parliament and then led the soldiers in the battle against the Kingdom of Beria. It was the battle where the Vicious Lightning Paragon's insight into the Lightning Law deepened tremendously, and he reached the peak of Emperor Rank. It was also the same day that he killed two Emperor Rank Warriors.
