After stripping the uniforms off the two soldiers, An Jing hid their bodies in a pitch-black corner. If one didn't search carefully, it would be impossible to discover that there were two corpses there.
Then, An Jing climbed back to Li Wuyu's side with the two sets of uniforms and the soldiers' weapons — spears — in hand.
"Put them on!" An Jing handed one set of the Chilin soldiers' uniforms to Li Wuyu and wrote these two words on Li Wuyu's palm.
Li Wuyu obediently put on the Chilin soldiers' uniform without hesitation.
An Jing also changed into the uniform.
Immediately after, An Jing placed a cap worn by Chilin soldiers on Li Wuyu's head and also handed her a spear.
With their disguises complete, Li Wuyu didn't need to ask to know An Jing's plan: to pose as Chilin soldiers and walk 'openly' around the military camp.
Just then, a squad of patrolling soldiers passed by. An Jing quickly pulled Li Wuyu to follow at the very tail end of the patrol.
