Li Xiaoran said, "It won't spoil. It's cooler in the underground passage, especially when the weather outside is hot. It'll seem much cooler inside. If you don't believe me, go into the underground passage and try. I think we have to open all the entrances in this underground passage to ventilate it. Otherwise, it'll smell bad inside!"
"I don't recommend opening all the entrances to the underground tunnels. We're too short-staffed to guard every entrance. If someone slips in, your people in the cave will be in danger," Luo Cheng said while shaking his head.
With that, Luo Cheng took out a porcelain bottle from his pocket.
"Bring two pills with you. They can improve the smell wherever you go, so you won't feel so uncomfortable!"
With that, Luo Cheng poured out two pills and stuffed them into the sachet Li Xiaoran was carrying.
Sure enough, after the two pills entered the sachet, the air around them immediately became much fresher.
