Jiang Ning turned around and, upon seeing Yuan Zhenyang's actions, her eyes flashed briefly, but she didn't stop him.
Only a fool would refuse the evidence and leverage handed to them on a silver platter.
Yuan Zhenyang stood up and walked to the back of a row of bookshelves.
When Jiang Ning had first entered, she had noticed that this was not Yuan Su's office, but rather the office of the deputy dean.
Yuan Zhenyang squatted beside the bookshelf, his movements practiced as he felt around the side of the shelf; Jiang Ning shifted her position slightly so that her phone's camera could capture Yuan Zhenyang's actions.
This movement of hers was mistakenly interpreted by Zhang Yonghao, who was nearby, as Jiang Ning being very concerned about Yuan Zhenyang's actions.
