Four Years of Sleepwalking, Waking up in a Pile of Monsters

Xu Zhen has been sleepwalking for about four or five years. Every time he sleepwalked, for unknown reasons, he would enter a fallen area where monsters were rampant and alien worlds eroded him. During the sleepwalking period, the physical strength, resistance to rules, pollution, etc. Reached a terrifying level. He knows the rules better than the rules here You happened to be passing by. He woke up halfway through killing monsters today. [Survival flow + no system + extreme reversal + violent aesthetics + black humor + cognitive dislocation] He thought he had traveled through time. The reader knows that he does not. By the time he reacts, the fallen area may have been completely destroyed. (PS: Don't go to the main text to remind him that he has not traveled through time)
