Feng Qing emphasized Feng Yuanzhou and Feng Jianing's reaction just now. Anyone could tell that Feng Yuanzhou's guilty expression at that time also confirmed that Feng Qing's speculation was very likely the truth.
However, towards this explanation, Xian Cheng's eyes revealed disappointment and dissatisfaction. When Feng Qing said that in the banquet hall just now, he thought that Feng Qing would take out some direct evidence. However, it turned out that this was only Feng Qing's guess. Moreover, Feng Yiru was no longer alive. Unless he could find Feng Yiru's real relatives, it was useless to say anything. That would not prove anything.
After thinking for a while, Xing Yue said, "How about this? I'll call Jintian and get him to bring people to arrest all the Feng family members. Then, we'll interrogate them strictly and force them to tell the truth."
