World Line Paradox

My name is Shi Jian, a former social reporter and now the unlucky person of the Time and Space Administration. My plans to leave my job were completely shattered by an elevator accident, and the culprit turned out to be a fake compass stuck on my face. When I woke up again, in front of me was a beautiful girl stationmaster carrying two swords. She gave me two choices: sign the deed of betrayal, or lie down in the luxurious one-way crystal coffin she prepared. Faced with this contract that can be called a "cosmic-level labor dispatch", I just want to ask: Is it too late to go back and lie in the coffin?
