The young master is reminded of a time when red lights appeared under the lake. Some demigod-ranking experts decided to look for a treasure, but the lights went off without a trace. The master rushes out to find the man who threw the gold. The man is from the soul-winged family, and he is reputed to be the "number one genius" in the Netherworld. He is not human, the master tells the young master, but his pointy ears and piercing eyes make him a suitable target for the search party.
