Xu Tui slept until dawn with 3% oxygen supply. However, he still felt that he was not sleeping well. The quality of his sleep was not high. It should be caused by lack of oxygen.
But compared to the many students who were yawning and had dark circles under their eyes, Xu Tui was in a much better state. Many students could not sleep at all under the 3% oxygen supply. Many of the people who were asleep triggered a life alarm and were sent to the oxygen chamber for treatment.
On the 21st day of his arrival at the extraterrestrial moon base, Xu Tui felt as if he had come back to life.
