"What are these students doing at night?" The soldier sitting in front of the surveillance monitors saw several figures flashing past and immediately zoomed in. He saw several boys entering the forest together.
He switched the cameras again and saw that the students did not enter the restricted area and took the intercom, contacting the sentries, "Sentinel No. 8, there are six students entering the Northwest area. Pay close attention to them."
"Sentinel No. 8 received, paying close attention." There was a response one second later. The sentinel placed the boys under the range of the surveillance cameras. They had no other movements after entering the forest and were sitting together and discussing something.
The trumpet sounded at eight o'clock, reminding all students to return to their dormitories to rest and regain their energy for the march tomorrow.
