If the person who came here was only Yang Ming, then Wang Kejin might not have made a move, because if Yang Ming were killed, then it would be hard to find his girlfriend. After all, from the information he brought, there was only data about Yang Ming. The information about Yang Ming's girlfriend was only slightly mentioned with nothing specific.
It could be said that after reading Yang Ming's girlfriend's details, Wang Kejin did not have any valuable clues other than knowing that this person was a woman. It was precisely because of this that Wang Kejin would be cautious in making a move. He was waiting for Yang Ming and his girlfriend to appear at the same time before he would start the assassination.
However, it seemed that tonight was a godsend opportunity. A woman was in Yang Ming's car. They seemed to be very intimate, so she undoubtedly should be Yang Ming's girlfriend.
