The protagonist Ye Ming was reborn after the team was wiped out during the escort mission and returned to the mission. He used the ability of "death retrospection" to start over again and find a breaking point in every cycle of being tricked, killed, and faked. But with each rebirth, the time window shortens, intelligence details are added, and the enemies continue to evolve. This is not a simple cheat but a desperate counterattack against time. He must find a balance at both ends of the scale - to save his comrades, or to save more people? Every choice is heartbreaking.
