I Don't Want to Die

If there is a chance to do it again, I just want to say that I don't want to die. The modern old man passed away full of regrets on his deathbed, but happened to be reborn in a fantasy world where there was no war or chaos, only everyone's desire to become stronger, and only mountains around him, making it a paradise-like world. Not only does he have a strong background, he also has a wonderful marriage, but is everything really so beautiful? This novel and its characters are purely fictitious.
