After school was finally over, Zhang Heng returned home with his schoolbag.
Instead of going home, as usual, he decided to pay the college hostel a visit. Although the student's face was covered last night, Zhang Heng could recognize him from his clothes. His Adidas sweatpants and the T-shirt printed with the word "Underground" had exposed his identity. He was wearing the same set of attire when Zhang Heng saw him in the convenience store.
Zhang Heng knew that last night, the college student had to be targeting him because he told no one about his plan to go to the river to investigate the drownings. He had driven his grandfather's car to the river, not to mention the relatively remote surroundings of the route he picked. While on the way to the river, only an occasional car would pass him by.
