I Have Lived for a Thousand Years

After the war between gods and demons, I survived. I lived for a thousand years and slept for a thousand years. When I woke up, the world had become unpredictable, with iron birds in the sky and iron lumps on the ground. Where has the world in my perception gone? Such a big world is gone. Then let me leave a true legend of compensation in this world. By the way, one more thing is that I am a devil, not a god. This novel and its characters are purely fictitious.
