This is a scene I saw from a manga from a long time ago. You, as the typical jr. high kid of manga-land, have the special power to accelerate human metabolism that got sent back in time about 2000 years ago. Your friend has been wounded by a poisonous arrow. While people in the past would probably die to such a situation, the kid from the future is armed with modern science knowledge and uses his special powers to cure the unknown poison. While according to him, any jr. high kid could've figured this out if they were in his shoes with the same powers, it sure wasn't obvious to me what to do until it was explained. I always figured that Japanese fictional jr. high kids are just really smart, but I'm curious if a normal person can figure out what to do in this case.
The solution is not a trick question and does not involve any further supernatural powers beyond what the kid already has.
