A popular actor transmigrated into a movie script and becomes a character that is supposed to die early! He can only return to reality if a natural anomaly occurs on the day of the peace negotiations between 2 countries. In order to live until "The End", and as a cinematic "king", he activates his survival mode...

Note: the title comes from a line in the poem 《走马川行奉送封大夫出师西征》by 唐岑参, talking about a general leading an expedition of soldiers. The original meaning of the line is that the general keeps his armor on even at night due to the harsh and dangerous nature of the expedition, but the double entendre here is that the general doesn't take off his clothes (refuses advances) at night.
