The chapter begins with the protagonist battling a surprisingly tough A-Rank White Python, noting its unique black line on its scales. This leads them to believe the python mutated due to a rare treasure. They follow the python to a cave, speculating that its den may hold this treasure, which could further enhance their abilities. The chapter ends with the protagonist discovering not one, but two mutated pythons in the den, setting the stage for a potentially difficult fight and valuable reward.
