Pu Zhang left Qishurg City with Gao Zhong not long after. Before he left, Yan Wang asked him what he meant about making Amon pay. He didn't answer the question. He said he needed to return to the capital first and request support from his superior, who was the fourth prince. He said once he was ready to act, he would let Yan Clan in on the action.
Even though Yan Clan could not do anything to Amon for now, it didn't mean they were doing nothing. They could not get to Amon, but there was another person they could target. The person was Gao Lan.
Many witnesses put Gao Lan in the same room when Gao Pan was murdered. She was the obvious killer. Although the death of an underworld member didn't concern the authorities much, the manner of Gao Pan's death did raise interest. After all, Gao Pan died from the same poison that killed several respectable citizens in the past. With Yan Clan urging these facts to the authorities, they had to go after Gao Lan.
