Ladder of Cause and Effect

On the space elevator 30,000 kilometers away, he received a message from the future: "Seventeen people will die in the accident." And his father-in-law, the chief engineer of the tower, knew all this five years ago. In 2046, mankind's first space elevator was built. Physicist Fang Yuankong was in a car 30,000 kilometers away from the earth when he received a message that should not exist - "At an altitude of 32,000, the air-tight ring failed. Seventeen people. Don't let the car go up." This is not a glitch, this is not an illusion. This is a warning from the future. What frightened him even more was that this hidden danger had long been flagged by his father-in-law and project chief engineer Lin Shen. Lin Shen chose silence. Fang Yuankong tried to prevent the accident, but found himself getting deeper into it. Each new piece of information told him: Accidents were going to happen, but he shouldn't stop them. He began to wonder - were those warnings from the future really helping him, or leading him into a trap? At the same time, his wife Shen Weiyang independently discovered the truth on the ground. She is faced with a choice: expose her father and save her husband - but she receives a message: "The way you save him, you will kill more people." The tower is there. The window is there. Information is flowing. The previous civilization also built the Tower of Babel. They also received warnings from the future. Then, they disappeared.
