In other words, as long as Fiona sold information about Yi Chengxuan to one person, she couldn't sell this information to others. If others wanted to obtain information, they could only buy it from the other criminals in Building No. 3. Assuming that only Fiona could obtain information about Yi Chengxuan, or that Fiona restricted the information that only she could sell to Yi Chengxuan, and Yi Chengxuan bought this information with money before everyone else, Yi Chengxuan's information couldn't circulate in the Land of the Fallen. Even Su Yu couldn't obtain information that didn't circulate. If this deduction was true, Fiona and Yi Chengxuan were on good terms.
Yue Xin thought about many things because of Su Yu's words, but not much time had passed. She did not answer Su Yu's words directly, nor did she refute them. Instead, she followed his words and said, "I'm following you now."
