Ruan Liuzheng was also tired by now and soon fell asleep.
Zhao Heng set aside his slight unease and continued organizing materials. The office became quiet again, and time slipped by, minute by minute.
With Zhao Heng's current physical condition, he wouldn't feel tired even if he worked through the night sorting materials.
It was not until 3 a.m. that Ruan Liuzheng woke up, feeling as if she had slept for a long time.
She opened her eyes, rubbed them, sat up, and saw Zhao Heng still engrossed in reviewing the materials. She couldn't help but admire him.
As expected, someone who has achieved so much at this age spends far more time and effort than the average person.
"Awake? Go sleep in the on-call room."
Zhao Heng said when he saw Ruan Liuzheng awake.
He could stay up all night and still work the next day, but Ruan Liuzheng definitely couldn't do the same.
"Teacher, I slept for a while, I'm not sleepy anymore."
Ruan Liuzheng replied.
