At three o'clock in the morning, Jiang Chen rushed into the emergency room with his daughter covered in blood. He is the world's most powerful agent, codenamed "Ghost." In order to give his daughter an ordinary home, he chose to retire and become an ordinary dad. Unexpectedly, as soon as his daughter entered kindergarten, he would be targeted by women with four identities at the same time - the contracted wife was a glamorous female CEO. When they met, she threw her marriage certificate and said: "Go home for dinner tonight." The savior was a genius female doctor who gave him a sickly smile: "Only I know your body best." The Interpol policeman who had been chasing him for three years slapped the table and asked, "Are you a ghost?" And the killer apprentice he taught himself was licking the tip of the knife in the dark: "Master, you can't escape." When the enemy came to the door, everyone thought that the single father was going to die - Jiang Chen loosened his tie and smiled tenderly at his daughter: "Nuan Nuan, close your eyes." The next second, death came. Who says middle-aged people are not frivolous? When Dad is angry, the whole world surrenders.
