Uncle Yu did this not only to anger Bo Junyan but also to mislead him. He wanted Bo Junyan to investigate Mu Huan's location according to the background of the photos and within the IP area where the photos had been sent.
To delay his search.
Thinking about what Mu Huan had said previously, he even got someone to send Bo Junyan such a message.
Xiao Huan had already forgotten you. She and Chenyi were now lovey-dovey. Don't bother looking for them. It's useless even if you find them. Why don't you let each other off on account that you were once family? It'd be good for both of you.
Uncle Yu was in a much better mood at the thought of Bo Junyan's furious expression when he saw the photos.
Since he treated Gu Chenyi as his past self, he naturally treated Bo Junyan as his former love rival. He would naturally not be polite to Bo Junyan when it came to things that he could not do to that person.
