As long as they were of the appropriate age, children could actively go to the city where the envoys were for an assessment.
As it happened, there was an envoy not far from Edgar's home. Edgar's uncle secretly took him for the assessment, not expecting his talent to be exceptional. He was immediately noticed by the envoy, who later became Edgar's master.
Decades passed, and Edgar became the chief disciple of the Mountain Sect.
The Mountain Sect participated in this True Dragon Water Palace treasure hunt, and Edgar was chosen by Owen Bertram. He entered the Ancient Annihilation Domain first, alongside a Sangdao monk.
After passing through the void tunnel, the Sangdao monk suddenly drew a sword from under his armpit! The sword was longer and narrower, and it was steeped in poison with a five-layer Array to silence its approach. It was indeed a Tier-5 treasure, and with a swipe, it pierced Edgar's body.
