Bitter Taste of Revenge

Eli was always in contradiction with his brother but to be betrayed? Sold off, becoming a lab rat? He was nearing death, when a bright screen appeared, whispering the words of bitter yet provoking hope "Do you want power?" He hesitated but with no other options he accepted. Within a breath, various selected individuals are teleported to a world with dungeons. From there, Eli had learnt his brother was somewhere in the new world and went in search for him. Revenge? Maybe, Overpowered? Yes.
