Gravis quickly found another Law Comprehension Area for the Law of Shadow's Darkness and went about comprehending his Law.
However, he quickly got interrupted by a Sect Master that appeared. This Sect Master wanted to know what had happened to the other Law Comprehension Area. After all, Gravis had never destroyed a Law Comprehension Area before. Their "cooperation" was solely based on the fact that Gravis didn't destroy the Sect Alliance's property.
Gravis informed the Sect Master that an assassin had attacked him and that it had been the Sect Master of the Sect that had owned the Law Comprehension Area.
After a lot of back and forth, the Sect Master decided to talk it over with the other Sect Masters. After all, one of them had become a Late Minor Circulation Immortal King without their knowledge. Additionally, the Sect Master Gravis was talking about had the Brilliance Element, not the Shadow Element.
