They ran rather quickly along the way.
Qiao Xiguan was practically dragged along by Gu Zichen.
Gao Song and Wa Da stayed close by their side, remaining highly alert.
Suddenly, a gunshot rang out from behind—they might have been pursued.
Gu Zichen bellowed, "Get down, hide."
Then Qiao Xiguan was pushed to the ground by Gu Zichen, her whole body in pain and still dizzy, when she was pulled again by him and hidden behind a large rock.
After settling Qiao Xiguan, Gu Zichen quickly assembled the black pistol in his hand. His expression was something Qiao Xiguan had never seen before—meticulous, cold, and tinged with a hint of bloodthirstiness.
"Don't come out; cover your ears. If anyone approaches, I've taught you how to shoot. Even if you get hit by a bullet, remember you're wearing a bulletproof vest, so don't panic. As long as you don't get shot in the head, you won't die," Gu Zichen said, each word deliberate.
What does he mean by not getting shot in the head?
