In a mix of virtual reality and xianxia, Aetheo introduces a world where people can access a virtual reality that allows them to train to their limits and beyond without worrying about dying. If they die in the training world, they will wake up in the normal world and can jump back into the training world exactly where they left off. The MC's problem? They've been thrown into a dragon's lair that they've been trying to escape for a thousand years. When they finally get out, there will be a reckoning.
