Beat them at their own game

The situation wasn't really like this?

"Young Valley Master, are you saying that the information we got was erroneous?" Yun Jin Wei said.

"That's right." Sima You Yue said, "Those bees I sent out yesterday night, sent news that the Zhan Clan and Sage Pavilion plan to move against you in five days. It's ten days earlier than the news you received."

"Move against us in five days? Haven't they yet to gather their men?" Guo Si Ming asked.

"No, they have already started gathering those people half a month before." Sima You Yue said, "They knew that you have spies hidden among them, so they wanted to beat you at your own game. They intentionally allowed those people to obtain that information and let them send word to you. They intentionally misled them to let you guys gather your men slowly. After that, they would act first and kill you while unprepared."
