Gao Tianyang was very alert and prevented Huang Zicheng from mentioning anything related to the mission, but revealed the investigation results to Huang Zicheng through chatting.Yao Yao, who was hiding in the dark, didn't find any real clues and secretly breathed a sigh of relief.Huang Zicheng once again asked Xiang Yang for a drink, trying to persuade Xiang Yang to ask Xiao Bai to meet him in Jinhai.
