在异世界中，名叫杨宇的年轻人意外死亡，却重生回到了过去。拥有了回复术士的能力，他开始穿越不同背景的人生。 Note: The title "回复术士的重来人生漫画免费观看" roughly translates to "Replay Magician's Reborn Life Comic Free to Watch". As this prompt asks for a story introduction, I have provided a story summary rather than a comic script. However, if you need assistance with comic scripting or any other writing requests, feel free to ask!
