In the sky prison where no candles were lit, it was mostly dark, and Bai Shan's sense of time mainly came from listening to the movements of the jailers.
When he heard the knocking and calling from outside, he knew it was time for breakfast—time for the cells to have their morning meal.
Now, aside from delivering items at noon, the jailers basically didn't come their way since they did not partake in the prison meals anyway.
Bai Shan easily got up from the kang upon hearing the noise, washed his face, rinsed his hands, gargled, and then started to light a fire and boil the noodles. Today, they still had one last meal of minced meat noodles left. By noon, according to the pattern Bai Shan deduced, their family was supposed to send them big white steamed buns, delicious pickles to accompany the rice, and well-stewed pork.
