Whether it was those who truly accepted An Ke in their hearts or those who only pretended to submit on the surface, everyone accepted the fact that An Yu was dead. In any case, no one dared to openly defy An Ke any longer.
In the following two days, with Hua Yan's covert assistance, Cheng Zixiao carried out a major purge within the Anyang Army, secretly taking care of troublesome staff and astute Deputy Generals with the help of Yun An. For those who were less troublesome, Cheng Zixiao simply dealt with them in the name of An Ke.
After dealing with some, naturally, others were promoted, all of whom were An Ke's confidants.
Once the confidants were promoted, they were even less inclined to believe the nonsense that An Yu had spoken about An Ke being an impostor. If An Ke were fake, why would he promote these close associates? By now, he would probably have wiped them out too. Thus, this An Ke had to be the real one.
