The Abyss of the New Life

The Abyss is a Gateway, a machine that let's you reborn in to a parallel Earth although when you die there you return back to the original world. To keep your brain fully functional and healthy the memories and experiences you live there starts to fade and disappear within 24 - 48 hours. However something unnatural appears when our Protoganist comebacks from the abyss and can't remember the original world. He gets stunned when His friend reveals him about dragons and Magic existing in this world and many more things to unfold.
