Hello, I read a light novel some time ago, but forgot it's name, but still want to continue chapters which were locked (need to buy). Book is about a man which come into vrmmo which was something like hell realm, mortal realm and heavenly realm. He was strong amongst players and was one of first people to play it (I think). When he got into game he found out that heaven realm was destroyed by strange demonized celestials (I think) or demons. He was found by people who came through heaven gate to look for treasure and were attacked. He saved them and they led him to mortal realm. There he found his old friend (which looked like old man) and went to hell with him later on. He was seen as teacher who helped mortals to cultivate when they recognized who he is from his avatar and he was like god to them. Thank you very much for your wasted time!!!
