Although Kang Zhaoming looked the same as Lin Yi, completely different from the Lin er they were looking for, this alone wasn't enough to eliminate them from the suspicion. Otherwise, they wouldn't be testing Lin Yi.
Putting his face aside, no matter how one looked at him, Kang Zhaoming was the biggest suspect.
First of all, he was a disciple of the rising Sky Pavilion, and he had a master like Xu lingchong backing him up. In theory, he should be above Lin Yi in terms of both Foundation and strength, and should be closer to the image of Lin er. Secondly, if he wasn't Lin er, why would he try so hard to divert their attention and frame the irrelevant Lin Yi? If it was purely for personal vendetta, why didn't he say that he knew how to use the pill fire bomb?
"It's easy to find out if Kang Zhaoming knows how to use the pill fire bomb or not-you can use the same trick you used on Lin Yi on him, and the truth will come to light!" South Heaven Gate sneered.
