Weird Recipient: I Picked up a Ghost Weapon at the Beginning

At three o'clock in the morning, I received a bloody letter. It says the rules: 1. At three o'clock in the morning, waiting in the dormitory. 2. Don't turn on the light, don't make a sound, don't agree. 3. After the door opens, walk in. 4. There is a "ghost weapon" in the copy, use it once, and you will lose it once. 5. Come back alive and forget everything - say, you will die. I thought it was a prank until the dormitory door opened of its own accord in the dark. Outside the door, there is the billowing gray fog, and the inhuman chewing sound deep in the fog. Someone else's newbie copy is Hide and Scream. But I picked up a rusty scalpel in the corridor of the dilapidated hospital. [Ghost weapon: bloody scalpel (broken)] [Effect: Stab a strange person, which can stop its "rule operation" for 3 seconds and expose its killing pattern] [Price: Each time you use it, you will permanently and randomly strip away one of your "physiological needs"] The first time I used it, I lost sleep. From then on, he stayed awake for 24 hours and became a monster in the dungeon. After the fifth use, I lost all pain sensation. He can break back broken bones without changing his expression, and use his body to block the weird killing rules. For the tenth time, I lost my hunger and fear. The survivors hid behind me and trembled, watching me walk toward those indescribable things with a knife. Later, letters of blood rained down, and the world fell. As all the survivors huddled in the shelter to pray, I pushed open the final door and walked in. The "administrator" inside looked at me with confusion in his voice: "What... Are you talking about?" "Me?" "I'm just a mail receiver"
