Fog: I Am a Player and Part-Time NPC in the Fog

This world has been invaded by strange fog for many years, followed by strangeness and death. The mist can be thick or shallow, but even if you live in the mist and inhale the mist over time, you will accumulate "grayscale" in your body. When the grayscale reaches the threshold, you may be transported into the mist realm at any time. Strangers who enter the strange realm need to complete specified optional tasks before they can return to the real world, otherwise they will be wiped out. Optional tasks have different star-level difficulties, and the corresponding rewards are also different. Rewards include various artifacts, scrolls, etc. That can deal with strange things. There are even various magical powers: body strengthening, transformation, deception... Players may choose tasks with different star levels of difficulty to obtain corresponding rewards. Therefore, their purposes in the mysterious realm may not be consistent, and the tasks may even conflict with other players, so that one of the players must be unable to complete the task and be eliminated. Therefore, there is more than just weirdness to worry about in the Strange Realm. In the Strange Realm, players are all trembling with fear, fearing being targeted by the Strange. Unfortunately, Shen Xu was transported into the Strange Realm and became a strange player. The difference is that in addition to being a player, he also "transforms" into an NPC in the mysterious realm. As long as he plays the role well, those scary and strange things will become "close friends and relatives" to him. In Gui Village, he "transformed" into the village immortal master and was about to preside over the River God Festival with young children as sacrifices. He teamed up with other tricksters to plan to kill the River God... In Water Margin, he "transformed" into Wu Dalang, and he designed to kill Wang Po and Ximen Qing... In the city, in Xianxia, and in Western Fantasy, he plays the role of an NPC in the mysterious world, overcoming obstacles all the way, gradually approaching the source of the mysterious fog...
