Nian Xi was very angry. She wanted to lock the door and let him stay outside in the cold wind for the whole night. However, it was her first day out after all. It would be bad if he caught a cold. Especially since this was the highland, they might have to go back home.
So, she let it go.
However, she was angry and couldn't sleep. She put on her coat and went to the roof to look for him.
On the empty roof, Jiang Yuning sat alone on a small stool with a tripod. No one knew what he was doing. He looked at the night sky alone for a while, then took a notebook to write something down.
He did not notice her when she walked over. Nian Xi saw that his notebook was full of data. It was so dense that she could not understand it anyway.
He was too serious that he didn't notice it when she walked in front of him until Nian Xi leaned over to look through his binoculars. "What exactly are you looking at?"
