Escape the Last Ten Seconds

No. 001 Woke up in a six-square-meter iron cell with no memory and only a piece of yellowed scratch paper in his hand. Blood words appeared on the paper: "You need to pay one-third of your life before using it." The countdown reaches zero, strangers continue to pour in, and the killer hides in the crowd. If you answer the puzzle correctly, you can get back in time, if you choose the wrong rule, you will be instantly annihilated. The note was the only guide, but it said: "Don't trust anyone, including me." When No. 001 Controlled the rules as "Master" and used the meaning of "Blank" to kill the killer, he finally opened the only door to life—— He opened his eyes in the nutrition cabin and saw the cabin label: No. 001, Consciousness Projection Experimental Subject. The last line of the note was slowly emerging from the paper: "Congratulations on successfully escaping and obtaining personality codename 001."
