Feng Luotian formed two wisps of conscience containing the information he got from Huo Zhihao's dead body and sent them toward the dumbfounded duo. He now believed that his master had nothing to do with Yin Clan. He trusted his own ability to detect people's emotions, especially when they were lying.
His first random guess about Vermilion Kingdom was just testing if Mei Hengkong would reveal the true culprit since he was old and experienced enough to easily speculate who they were.
And because his master corrected him right away, it ruled out the possibility of Mei Hengkong being Yin Clan's collaborator.
Who in their right mind would expose their partner's misdeed to others without pointing it the other way?
As for Luotian's second random guess about Second Elder, he wished to see how Mei Hengkong would react and gain some clues in the process.
