This Madman Is Restarting Paradise Lost

[Weird arrival + novel setting + unlimited flow + no Holy Mother + no brainlessness + no system] Four years ago, everyone in Zhou Yi's high school disappeared mysteriously, and he himself lost himself due to guilt about something, and remained in a state of confusion for four years. "What have I done? What am I doing? Maybe it was just a fleeting dream." Today, he finally returned to four years ago in his dream? I thought I had gone back to the past and wanted to keep everyone alive. ​In fact, it is... "Someone is establishing [contact] with Lost Paradise, and he wants to restart [Lost Paradise]!" "What a madman. Find him quickly and stop him!" One day later, they successfully found a dark house. The walls of the house were covered with many strange symbols. The lines were twisted and intertwined, as if telling some evil secret. There are also many elusive words, the handwriting is scrawled and crazy, which makes people's hair stand on end. A mysterious man pointed to the corner and exclaimed. The group of people quickly looked there and saw a curled-up 'withered skeleton' lying there. The 'dry bones' were shaped like dry wood, as if they had been dead for a long time. "No, he is still alive! He is the one who is contacting [Paradise Lost]!" Another mysterious man turned pale and said with a trembling voice, "He has restarted [Paradise Lost] and there is no way to stop it!"
