Upon hearing this, the nearby few people nodded frantically.
Qin Feng said, "It seems there is indeed only one possibility."
"Otherwise, who would smear blood for no reason?"
Thinking of this, Qin Feng felt a surge of excitement inside.
If it can be confirmed here that the bloodstain is Li Ailing's, then the subsequent interrogation of Zhang Xiang would be like adding wings to a tiger.
Even if he says nothing, it might be possible to rely solely on this bloodstain to completely breach the defenses from that year and take him to court with zero confession.
He twitched his lips and said, "I'd like to see how Zhang Xiang argues his way out this time!"
Quickly, Jiang An took out a swab and distilled water from the toolbox, moistened the swab, and immediately began collecting samples at the fluorescent reaction spot.
After finishing all this, everyone let out a deep sigh of relief.
