In navy blue, he carries the souls of countless fallen comrades.
Half a lifetime undercover, he tramples through an abyss ten thousand feet deep.
Clear-headed restraint was the foundation of Jiang Yanhan's life; bearing heavy burdens was his daily lot.
He watched his senior brother Lu Zhenggu die beneath a drug lord's gun, his blood staining the police badge red.
He infiltrated a drug den as an undercover agent and became the second-in-command under Shen Wangjin, a top drug lord.
The oath he swore at the police academy still rang in his ears, while the mire of his undercover life had long since closed over his head.
Some rot in the darkness; others hold fast in the face of despair.
Jiang Yanhan said, "I'm not afraid to die. I'm only afraid the badge will be disgraced, and the fallen will be forgotten."
From the police academy to the drug den, from youth to old age.
The torch passed down through three generations; the regrets of two generations finally came to an end.
Even if the moonlight shatters to dust, even if the road ahead is overgrown with thorns,
that police badge will never bend,
and that faith will always face the sun.
Theme: In navy blue, he guards the nation's soul; with every beat of his heart, he prays for peace across the land. He keeps drugs beyond the nation's borders, so the lights in every home can shine on. Faithful to the country, the people, the spirit of the police, and those who sacrificed their lives
