Although his face was covered, Ye Weiming was not an NPC, hence he didn't suffer from the severe face-blindness disorder that would make it impossible to recognize a familiar person once half their face is obscured.
Was the intruder in the Xuanxu Chan Room Xiao Feng?
Ye Weiming was initially slightly taken aback, but then quickly realized that this person just looked extremely similar to Xiao Feng. Nonetheless, there was a significant obvious difference between the two.
Upon closer inspection, you would find that Xiao Feng was not this old!
If one had to guess, this person feels like...a fifty-year-old Xiao Feng?
So... he must be Xiao Yuanshan!
