When Yu Baoyin wanted to peek, she only realized that there were two mirrors on each side of the chimney stack.
"Where did these things come from?" She mumbled..
Nanzhi uttered without blinking, "I saw them floating around."
"Eh…"
The noise continued and Yu Baoyin became more curious.
However before she can move her head, Nanzhi pinched the back of her collar.
"There is a sniper." Nanzhi warned and showed her a crushed bullet shell. It was from her rifle though but Nanzhi used it, so she won't waste time explaining.
"W-what? A sniper?" Yu Baoyin's face became pale when she saw the bullet.
Of course, she knows what a sniper is!
There were also people with guns inside the building.
No wonder Sister Nan had been hiding in the back of the chimney!
Yu Baoyin also pressed herself closer to the point she wanted to meld with the bricks.
