"That's right, we both thought so at the beginning, but it turned out..." Cheng Nan stopped halfway through speaking, and just looked at Zhang Mei with a confused expression.

"Ahh Zhang Mei suddenly screamed, because after Chengnan's reminder, Zhang Mei suddenly remembered that she and Chengnan had not seen Xu Jianjun's body since they rescued Chen Xiong from the coffin.

Chen Xiong's body is missing!

"Chen... Male... What about corpses... Zhang Mei said a little tremblingly.

"I don't know, I'm thinking about it too." Seongnam shook his head and said. This question is exactly what Chengnan is puzzled about, how could this Chen Xiong's body disappear for no reason.

"This... Chen Xiong was tied up in a coffin at the beginning, do you think it could have been done by the person who tied Chen Xiong? Zhang Mei guessed.

Seongnam said: "I've thought about this, and this possibility is the greatest." ”

Seongnam replied as he seriously squatted on the ground and examined every part of the deceased's body, hoping to find some clues from it.

"Is this...?" Seongnam's eyes lit up, and he suddenly noticed a small flesh-brown thread on the arm of the corpse.

Seongnam carefully pinched the small section of the line with his hand and put it in the palm of his hand to examine it carefully.

Zhang Mei squatted beside Cheng Nan, and when she saw Cheng Nan pull out a line from the corpse's arm, she suddenly wondered: "What is this thing in Cheng Nan?" ”

"Sheep intestines." Seongnam-do.

Zhang Mei frowned when she heard this, and said suspiciously: "Sheep intestines? What is sheep gut? ”

"This sheep intestine is a kind of dissolvable surgical thread, which is used to suture wounds, it is made of protein, because this kind of thread can be automatically dissolved and is harmless to the human body, so sheep intestine is widely used in today's surgical sutures." Cheng Nan frowned and said, although he knew the origin of this thread, but this should be on Chen Xiong's corpse, how could there be such a surgical thread for suturing, and Cheng Nan glanced at it just now, this thread was sewn in the arm, could it be that Chen Xiong had surgery on his right hand before he died.

"Surgery!" At the mention of surgery, a flash of light suddenly flashed in Seongnam's head. Chengnan's eyes lit up and he asked urgently: "Officer Zhang, I remember that you said at the beginning that Xu Jianjun was able to get his right arm back because of the timely rescue, isn't it?" ”
