Ning Ning, in private, had looked up information on Ye Wei despite Mo Jue threatening him that he would kill Ye Wei if Ning Ning tried to look up information on Ye Wei. Mo Jue planted misleading information on Ye Wei's traces to deliberately mislead Ning Ning.
Mo Jue had hacked the mainframe of the terrorist organization's satellite system, and it was still under repair. Since time and technical skills were needed, Ning Ning lost his best tool to track Ye Wei and Eleven and had to gather information about Ye Wei through other means. He preliminarily determined Ye Wei was in the Middle East based on Big Boss Mo's recent activities. Since Big Boss Mo was recently active in Colombia, Ye Wei could not be far from there.
