The terrorist incident that occurred in Japan some time ago not only shocked the world, but also threw the National Security Bureau into a state of chaos. The National Security Bureau, in face of this major event that came without warning, shockingly received no prior intelligence. This was terrifying. The problem was serious and involved national security, causing the entire Bureau to go into overdrive, searching for any possible leads. If they couldn't get to the bottom of this, they would be in dire straits. During that time, the Bureau was under considerable pressure from all sides. Even Director Liu almost lost his job over this. However, the Tokyo incident was extremely suspicious, the terrorists behind it were highly skilled, and they didn't leave any discernible traces. Despite using every method at its disposal, the Bureau still couldn't find any evidence.
