It is reasonable that Yin Jin did not die in the aftermath of the explosion. After all, Ou Zhenhai has long said that he should keep alive, otherwise he would not be able to make friends. In addition, Ou Zhenhai also needs Yin Jin to provide clues to criminal organizations in the nearby coastal areas, and to wipe out Yin Jin's smuggling gangs.
The helicopter was destroyed by an unmanned aerial vehicle just now. It must have been before Yin Jin got on the helicopter. If Yin Jin got on the helicopter and started again, Yin Jin would fly away with the helicopter.
Of course, I don't want Yin Jin...
