The expressions worn by the old men only grew uglier. They all knew that if Xu Rouguang indeed wished to kill them and wiped out evidence, he was very capable of doing so. No one could tell him otherwise. Before, Shanxue or Mao Jixue didn't even warn him; now, Lai Mingyan seemed to do the same. After all, what Xu Rouguang said was true: he was held by duty to kill them off.
However, Patriarch Tang was a little smarter than the rest. It's just that… even if he did realize that, it wouldn't help with the situation. If Xu Rouguang indeed was free to kill them just like that, he would have done so in a flash. No one would incriminate him at all. However, he did not. It was clear that he was still monitored by a power that he could not easily go against.
