Yun Chi opened the window, and a gust of cold wind hit his face, plunging the study into a chill in an instant.
Little Zhongzi immediately whispered, "Your Highness, it's deep autumn now, you can't stand in front of the window and be exposed to the cold wind for too long. Be careful not to catch a cold."
Yun Chi hummed in acknowledgement, standing with his hands behind his back, and didn't immediately close the window. He turned to Little Zhongzi and said, "She's been to the Northern Region for half a month now, hasn't she?"
Little Zhongzi promptly replied, "Yes, Your Highness, today makes it exactly sixteen days."
Yun Chi nodded, sighed, and said, "I wonder how many sets of sixteen days it will be until she can come back."
