Before ending the meeting, Ouyang Ping made a summary: "Today, Director Feng personally participated in our case analysis meeting, and he was able to take time out of his busy schedule to care about this case, which is a great support for us; Guo Lao is also here today, he is so old, he still cares about our work, and we have no reason not to do our work well. Under the inspiration of Guo Lao, our thinking has also been much more open. Next, we will investigate from three aspects, the first is the boat, the second is the characteristics of the deceased, and the third is the city wall bricks, whichever way, the focus of the investigation is on the area along the Qinhuai River. ”

After the analysis meeting ended, Ouyang Ping arranged for Li Wenhua and Liu Wenbin to prepare the content of the notice, which must be taken out tomorrow morning, and then posted and sent out.

After that, except for Li Wenhua and Liu Wenbin, everyone else went to the forensic department with Guo Lao.

Two wall bricks lie in the corner next to the freezer, and the wall bricks are placed in two snakeskin bags.

Liu Dayu opened the two snakeskin pockets, revealing two black, stinking city wall bricks.

Chen Jie put on gloves and used a knife to slash the snakeskin bag from head to tail.

The bricks of the two walls are the same size: 48 long. 5 cm, 28 wide. 5 cm, 20 cm thick. There is still some text on it, but due to the long-term erosion of wind and rain, the text has been blurred.

Chen Jie put on a mask, squatted down, and gently scraped the brick surface with a knife, and under a layer of black silt, there was indeed a layer of soil, but due to the soaking of the silt, this layer of soil had been polluted to brown. The thickness of the soil layer is about 0.6 centimeters - in some places there is it, in some places it is not - and when the workers build the wall, the mud will not be evenly smeared. Chen Jie was a little disappointed - the 0.6 centimeter thick soil could not withstand the soaking of the silt for two months.

"Lao Chen, you turn the bricks of the city wall over." Ouyang Ping was unwilling.

Yan Jianhua put on a mask and gloves and turned the two city wall bricks over.

"There's a notch in this brick." Left to the east crouched on the ground and pointed to a brick road of the city wall.

At the left to the east, there is indeed a "V" notch, and the lower half of the notch is filled with dirt. The location of the incision is at the right angle in the middle of the bricks of the city wall, to be precise, it is a gap, the depth of the gap is about five centimeters, and the maximum width of the opening is about 105 centimeters.

Chen Jie used the tip of the knife to slowly scrape off the black mud on the surface of the gap.

Li Wenhua didn't know where to push a surgical cart, and the city wall bricks were moved to the surgical cart, and the person was very uncomfortable squatting on the ground, his eyes could not see the gap at close range, and the light was relatively dim.

Chen Jie and Yan Jianhua moved the city wall bricks to the operation car, and now, Chen Jie's position is much more comfortable. Guo Lao asked the attendant to bring an emergency lamp, and the light of the emergency lamp was very strong, so that he could see the color of the soil in the gap.

Guo Lao laid a blank sheet of paper in the operating car.

Chen Jie used the tip of a knife to dig out the soil in the gap little by little, and spread the soil out on the white paper.

Under the strong light of the emergency light, the color of several stalls of soil changed from dark to bright, from dark black to light yellow, and then from light yellow to positive yellow, probably because it was soaked in water for too long, and the loess had a certain humidity and viscosity.
