After returning to Sea City, Wu Chengyue had been paying close attention to the underground creatures that had shown up near Sea City Base. He had been sending out his men to collect information about those creatures. While trying to figure out their features and weaknesses, he had also been trying to find out about Huaxia Base's recent movements.
Huaxia Base had called for a grand meeting and invited all base leaders to talk about the underground creatures. Who knew if they would play some other tricks under the cover of the meeting?
Mankind needed to unite to win the war. But, judging by Si Kongchen's previous behavior, he might grasp the opportunity to stab Sea City Base in the back while everyone else was fighting against the underground creatures, and destroy Sea City Base.
After all, Si Kongchen's true purpose would only be keeping Huaxia Base safe. He wouldn't want to help anyone else.
