Identity mystery: Lin Hanyue appears to be a business elite, but in fact he holds key technologies needed by the military. Behind her "accidental encounter" with Ye Lingxiao was a plan carefully designed by the top military officials.
Crisis reappears: When mercenaries attack Dongchen Building, Ye Lingxiao has to show his true strength in front of everyone, and at the same time discovers that the traitor from three years ago is right in front of him.
