Qin Lie discovered that not only did he have an irremovable countdown in his retina, but he also awakened the "crisis reminder system". This system can pop up a red alert when he faces a certain death situation and analyze the only way to survive.
Qin Lie used the system to shuttle between the chaotic future city and the wasteland battlefield, and gradually grew from a hunted fugitive to a "ghost" that frightened the dark forces. While he was searching for the truth about his actions back then, he was protecting Doctors Without Borders Su Qing, who held the key biochemical key. The two fell in love with each other during the war, and eventually joined forces to crush the "Titan", a transnational military group that intended to trigger World War III by creating "puppet soldiers."
