The Howl of Blades, the Ring of Guns

Undercover police officer Gu Yixing * frontline military doctor Jiang Yu

The first time Gu Yixing and Jiang Yu met, Jiang Yu nearly stabbed straight through him.

When they meet again, Gu Yixing looks at the scalpel in Jiang Yu's hand. "Dr. Jiang, go easy on me this time."

Looking at the bloody, mangled wound, Jiang Yu wonders how anyone can still joke around in a situation like this.
