"That's right!" He Xing nodded. "When we were on the expressway, we were listening to the interview, so I didn't pay much attention. However, after we came off the expressway, our speed dropped and I didn't hear the sound of our wheels crushing the bugs."
Qinghe City was plagued by bugs. Even when they were on the expressway, they had to spray insect repellent and scatter medicinal powder when they parked their cars to sleep at night. Even last night, the soil around their car was still full of bugs crawling.
Du Yue was still trying to figure it out when she heard He Xing speak again, "There were still many bugs at the place where we slept last night. The bugs must have disappeared from this part of the road today. It was a pity that we didn't notice it at the time, so we don't know what's the difference between this road and the one earlier."
Du Yue furrowed her brows. "What's the difference between this place and Qinghe? Why isn't there a bug disaster here?"
