"Leorio!" "Big x Time x Interview" "Gon's group has been trapped by the vipers that block the exit." "But the vipers' master, Bourbon, is already dead." "The one who set this trap is dead?" "How?" "I killed him." "I won't tell you how." "Gon, take Leorio." "Okay." "It's no use." "You won't be able to search his body." "The snakes are trained to attack the moment anyone tries to touch their master or to leave the cave." "So you used poison to fight poison." "Judging from his wounds, you must have used Neurotoxic Bees." "He probably died from anaphylactic shock." "Anaphylactic shock?" "When a bee stings a human, the human produces antibodies to counter the venom." "But if that human is stung again by the same kind of bee, they experience an allergic reaction." "An extreme allergic reaction is known as anaphylactic shock." "Depending on the circumstances, it can be fatal." "You got me." "That's exactly what happened." "So you used bees to kill him?" "Bourbon was my target." "After confirming that he'd entered the cave," "I sprayed sleeping gas into the entrance, and waited until it was safe to enter."
