In 2106, a major death row prisoner escaped from the time and space prison and traveled to a time and space to cultivate immortality. For the safety of mankind, the state sent Shi Shen, captain of the Criminal Investigation Brigade of the Tianjin General Administration, to take Song Jinghong, an outstanding student from the police academy, to travel back to that time and space to catch the death row prisoner and kill him on the spot. During this period, Shi Shen went from looking down on Song Jinghong, to falling in love with him, to being willing to die protecting him.
Intention: I want to protect you, even if I die.
