Ling Jiushi helped the injured mysterious person enter the inn in the village to take a rest. He learned from a man named Xiong Qi that in order to leave this game world, one must solve puzzles and find the key. The mysterious person claimed to be named Ruan Baijie. He warned Ling Jiushi not to tell his real name, but Ling Jiushi didn't listen. That night, a player was killed by a woman in white. Everyone learned that the cause of his death was violating the taboos inside the door. In order to find the key, everyone agreed to the village head's request to ask a carpenter to make a coffin, which should be related to the key.
