The reason why Su Yun chose to hide himself was because of what Xu Jiajia had said on the phone.
Don't trust anyone.
With Su Yun's current state, any leak of news could result in death. Therefore, Su Yun chose to hide. Only by hiding in the dark could he control the situation. As for the concealment method, it was naturally all thanks to Xu Jiajia.
Su Yun had learned many ways to hide his whereabouts from Xu Jiajia. Although this was his first official attempt, the effect was very obvious. He quickly found a self-service printing shop and printed out the document sent by Xu Jiajia.
Su Yun picked up a pen beside him and drew a circle on one of their names.
Xu Jiajia was really not simple. Not only could she obtain all the identity information of these shadow-like people, she could even have a rough understanding of their movements. This undoubtedly provided Su Yun with great help.
