"Bang bang," several sounds erupted, and a thick cloud of smoke suddenly filled the hall, followed by the instantaneous disappearance of the lights. The darkness, compounded by the smoke, rendered the hall so dark that one couldn't see their own hands.
Ninja!
This was the kind of smoke commonly used by ninjas for concealment. Gonpachiro still had some ninjas hidden here; they had been lying in ambush within the hall, and now that Li Yifei had entered, it was finally their turn to strike.
The most formidable trait of the ninjas was their ability to ambush, killing their victims silently and without prior warning. Moreover, these ninjas were the elite among their kind, a group of true masters nurtured by Gonpachiro at great expense.
In such a situation, a regular person would definitely stop in their tracks, but Yifei's pace wasn't affected in the slightest, his steps still methodically moving toward the direction of the staircase.
