Gu Sanning walked back the same way, and met many prison guards and prisoners on the way, and several of them had familiar faces, as if she had wandered around the area before she followed the female prisoners.

Gu Sang's gaze flashed a different color, and he didn't rush back, but sat on the bench next to him, looking at the people walking back and forth in the square.

After an hour of observation, she found some kind of pattern.

Hundreds of people went back and forth in the square, and several of them seemed to be set, going back and forth twice, repeating inconspicuous movements.

If you hadn't deliberately paid attention to the surrounding environment when you hadn't followed the female prisoner, you might not have noticed this kind of repetition.

Gu Sanning got up from his chair and walked in the direction of the lodging building.

He knocked on the door, and after a while, He Xila opened the door, yawned and walked back, and asked, "Where have you been here, you have been going for so long." ”

"Nothing, walk around." Gu Sanning replied, picked up the plastic basin on the bed, "Let's go, there are fewer people now, take a bath." ”

He Xi answered in the back, and took the change of things to follow.

Entering the public bath, Gu Sanning chose a random place to enter, and He Xi hummed a song and walked to the place where she showered yesterday.

There was someone in the compartment, and the sound of running water was heard.

He Xi didn't pay much attention, took off his clothes, tested the temperature of the water, started to shower, hummed a little song all the time, inadvertently glanced at the ground, and screamed.

Gu Sang Ning heard He Xi's scream halfway through washing, hurriedly turned off the shower, quickly put on his clothes, took a pistol, pulled the curtain and walked quickly inside, because his steps were too hurried, he almost slipped, but fortunately, he stabilized his body in time.

"What's wrong?" Gu Sanning stood outside the curtain and asked.

"Blood, blood!" He Xi couldn't stop the trembling voice came.

"It's okay, I'll take a look, you get dressed first before you come out." Gu Sanning said, avoiding the wet place on the ground, walked to the shower room next to He Xi, opened the curtain, and there was a person lying inside, wearing a prison uniform, and the water from the shower continued to wash her body, flowing the blood and water under her body into the mouth of the sewer, and the excess spread to the next room.

From the pale face with his eyes closed, Gu Sanning could tell that this was the girl who was following Ye Sheng.

Gu Sanning put away the gun, walked in and turned off the shower, probed his nose, the person was already out of breath, and his hand touched the person's neck down, and there was indeed no pulse beating.

Even though the water was turned off, the blood behind him was still flowing.

Gu Sanning turned the body over, blood and water soaked the fabric of the upper body, and after careful examination, he found that there was no obvious trauma on his body, and the blood on his neck was flowing down from the back of his head.

Gu Sanning was about to reach out to touch it, but then there was a scream from He Xi, and when he looked back, He Xi was covering his mouth and staring, looking extremely frightened.

"Turn your head away and don't look." Gu Sanning used his body to block it.

He Xi stiffened his body and did so, while Gu Sanning behind him brushed away the person's hair and checked the wound on the back of his head, half the size of a finger, the depth was the size of a fingernail, and then he looked at the wall with blood stains but it was smooth and complete, as if it was not caused by a fall.

Apparently, someone first hit the deceased in the head with a blunt object, and deliberately faked the scene of the accidental death.

Gu Sanning touched the corpse, it was not stiff yet, there was a coldness on the surface of the body, and the cold water that was turned off just now showed that the person had not been dead for long.
