Demon King's Development Diary

Jun Mo Ran, an older and homeless young man, was unlucky enough to travel to another world due to a computer explosion, but sadly discovered that he was no longer the protagonist? Not a supporting character, not a villain, not even at all, not a living thing... Jun Moran: Heaven, earth! If you want to beat me to death, just tell me. You don't need to do anything, I will do it myself. If someone else travels through time, he is not the protagonist, but he is still the villain at any rate. Even if it doesn't work out, why don't you treat me like a beast? You asked me to travel through time and become a stone. What the hell is this?
