Yongchun City, with a total population of 7.67 million, governed seven districts, two cities, and one county.
With such a vast population, Yongchun Train Station was naturally bustling with constant vehicle and pedestrian traffic.
When the train arrived in Yongchun, it was a little past nine in the morning, the peak time for foot traffic at the train station.
Upon reaching the final stop, the train, which had traveled nearly two thousand kilometers, began its regular maintenance.
But away from people's attention, a large, dark Chinese Anopheles Mosquito quietly took flight from the underside of the train and ascended into mid-air...
"Huh?..." A train attendant seemed to catch a glimpse of something, then blinked and dismissed it from his mind.
He must be seeing things. Where would such a big mosquito, carrying a small bottle, come from?
