The next day.Early in the morning.Zhang Ye stretched and got up from bed.This was officially his first day at the research inst.i.tute. As he had gone to bed soon after arriving yesterday, he woke up very early today after getting a good night's rest. Out of habit, he turned to the window and opened it. Then he sang out the window a familiar tune: "Tears Behind Prison Bars."In the opposite building, Chi Xue sat up from under the covers.Fellow Zhou, who was living in the same dormitory block, was also woken up in surprise.
