Folding Threshold

In 2045, the world's first Earth-Moon quantum folding project was completed. The 1,200-meter folding tower stood in the northwest Gobi, realizing instantaneous material transportation between the Earth and the Moon's Sea of ​​Tranquility base, supporting the national lunar helium-3 mining plan and the clean energy layout for the next fifty years. Zhou Yuanhang, a structural engineer at the No. 7 Maintenance Station, a rural young man who always carries his father's legacy - an old-fashioned vernier caliper in his pocket - discovered an abnormal deviation of 0.00031 Mm during a routine inspection. This tiny number, which was automatically filtered out by the AI ​​system, led him step by step into the deepest secret of the project: his mentor, Lin Guodong, the first-generation architect of the project, did not die from an "operational error" three years ago, but actively sealed his consciousness into the quantum fluctuations of the folding channel, turning it into an "anchor" waiting to be triggered. When the urgency of the game between great powers collides head-on with the bottom line of human nature, and when the weight of the "big picture" presses on the shoulders of every ordinary person, Zhou Yuanhang must make his choice between his sister's surgery expenses, his mentor's last wish, the dignity of more than 200 compressed people, and the country's space strategy. A vernier caliper with an accuracy of one ten thousandth of a millimeter can measure the tolerance of a titanium alloy valve. Can you tell whether the ruler in your heart is crooked or not?
