Just now, when Feng Dahai pointed the gun at Anna and scared her, then kicked her twice, everyone's attention was focused on Anna and Feng Dahai; nobody noticed that the ropes that bound Li Teng in a complex knot had somehow been broken free of!
When Feng Dahai was about to turn around and execute Li Teng with his gun, Li Teng had already, like a ghost, appeared behind him, with something in his hand that looked like a scalpel. With one swift cut, he severed Feng Dahai's carotid artery, then grabbed him by the hair and slammed his head into a nearby pillar.
Following Anna's lead, Li Teng completed the second killing of Feng Dahai!
And it was likely yet another miraculous counterkill!
It was clean, quick, accomplished in one stroke.
Until the moment of his death, Feng Dahai had no clue how Li Teng had managed to free himself and sneak up behind him.
