In his previous life, Xu Yun, due to the nature of his freelance profession, had a relatively flexible schedule every day, so over time, he developed a sort of underworld biological clock.
It meant sleeping at three or four in the morning and waking up at one or two in the afternoon.
Such a routine over the years led Xu Yun to develop reflux esophagitis, causing stomach acid to burn the esophagus.
However, after being reborn, he deliberately adjusted his sleep habits. Although his scientific research work inevitably involved staying up late, overall, his sleep schedule became more in tune with the living world's pattern.
Hence, when the urging voice came from outside at three quarters past Mao hour, Xu Yun quickly woke up.
"Hey, inside the room, get up early!"
"...Oh, coming!"
Xu Yun rubbed his sleepy eyes, responded simply, and got up to dress.
