Blood Moon Strange World, Welcome to the Corpse Farm

Jiang Wanwan almost died in the line of duty and became a vegetative state. Because of her tenacious will to survive, she came to a strange barrier shrouded in a blood moon. From then on, she held two butcher knives in her hands, hugged the boss's thigh, and began to run rampant in the dungeon. After clearing the dungeon, she can return to the human world. She has seen poisonous vines that transformed into beautiful women, butchers who treat people like two-legged sheep on the table, and wizards with heads that can still fly all over the sky after their heads fall to the ground. Jiang Wanwan slashed each NPC and each BOSS. The cold mechanical sound echoed in the dungeon. Players who did not follow the rules would be wiped out by the system. The next moment, Jiang Wanwan slashed at him with a butcher's knife. What are the rules? I am the rule?
