Countdown Between Cause and Effect

Lin Mo is twenty-six years old, a social creature, living alone and with few friends. He could see the countdown to death above other people's heads. Bright red numbers hung in the air, as if they were painted with blood. The moment time reaches zero, whether you are eating, walking, or sleeping - you will die. He verified it twelve times and never got it wrong. But on the thirteenth time, the number appeared on a living person's head. A system pop-up window followed: Interventionable event. Successful intervention rewards Karma Points: 3. He snatched the first person back from death. The balance of points begins to increase - but each time it is added, the total is a little more than the addition. It seems that one account was recorded incorrectly from the beginning. A mysterious man appeared downstairs in the early morning and left a note with only four numbers written on it: 0425. A midnight break-in into the B2 underground garage of Jin Mao Tower revealed a secret that started in the Antarctic ice cave in 1978 - twenty experimental subjects implanted with bone spurs, a slaughterhouse disguised as a culture room, and a closed system that can exchange causal points for the authority to intervene in death. The root node of the system is his grandfather Lin Yuanzheng, and the architect is his father Lin Jianguo. And Lin Jianguo has been dead for many years. In an abandoned ward on the 18th floor of Jin Mao Tower, he carved nineteen names on the four walls, using the bone spurs in his palms as carving knives - and then deleted himself from the system. What was left to Lin Mo was: twelve letters sealed in an old-fashioned hard drive, an orange cat that could type on a mobile phone with its paws, and a countdown running in reverse.
