Sky Cable 72 Hours

In 2080, mankind's first earth-to-moon ladder (Kunlun Sky Cable) was suddenly involved in an interstellar war. Chen Mo, an ordinary cable repairman, was trapped at an altitude of 30,000 meters. Isolated from top to bottom, oxygen counts down, and the flames of war spread along the ladder.
