Rewriting The Magician's Past

Today is a very special day Because today is the day I will be able to change my fate. Not by rebirth, But by letting a lost soul take control over my body. But there is a catch. The burden is far too much for an ordinary person. There will be many obstacles in the path of rewriting my life. But the fate of my world rests in his hands. From the greatest Magician, Samuel Merlin, To the lost soul of another world. Please rewrite my life. I entrust it to you.
