September 20 Year 30,766
Three months have passed after the incident at the beach. In these three months, nothing eventful happened aside from Cairo's jaw-dropping improvements. If before he was at the average level of the mages in the Larton Kingdom, he is now at the genius level!
Del knew that Cairo can meet the standards of the geniuses but he thought that it would take a few years. He never thought that it would be this fast
As smart as Del, he knew that this improvement started when the unresolved incident at the beach happened. However, since the Queen only cares about if Cairo is safe, he didn't ask Cairo if something happened back then that even he doesn't know
Most of Cairo's improvement is credited to the legendary being sealed inside him and the abundant crystal soul shards that he has at his disposal
