Equivalent Exchange: I Demanded Double

Synopsis

This world was governed by the rule of "equivalent exchange." Anyone could ask the altar for a wish, but the price was losing a part of their body at random. Some people wished for unimaginable riches, only to pay with their eyesight. Others craved unmatched power in battle, but ended up losing their hearts. The altar asked me, "What do you want?" I said, "I want you to double every price you're about to demand from me." The deity on the altar was stunned, and every screen in the world glitched for a moment. Since the price was random, what if I asked to give up my death? With the whole world watching in terror, I became the only eternal being in this world governed by rules.
