Under the control of Master Chen, the bucket slowly lifts up and slowly moves towards the truck, and when the bucket exceeds the height of the truck's body, the bucket continues to stretch forward.

Captain Xiao waved his hand, and the bucket slowly fell; Six workers rushed up, climbed onto the truck, and slowly moved the edge of the shaft to the truck and stabilized.

Captain Xiao had already greeted Master Chen before, although the edge of the well was a stone, it was an important cultural relic, so it must be handled with care, and the pattern on it should not be broken. Therefore, several masters are very careful when operating.

During the process of moving the edge of the well to the truck, Professor Nie and Professor Jin stood on both sides of the truck, staring intently at the edge of the well.

When the truck slowly drove out of the scene, the crowd that had just stepped back and moved out of the way quickly gathered again. At this time, the sky seemed to be painted with a layer of black paint, and night had fallen, but the number of onlookers continued unabated.

Zhao Zimeng looked up, there was not a single star in the night sky, his eyebrows frowned slightly, and he secretly prayed that the sky would be beautiful and that it would not rain.

In particular, it must not rain heavily, as once it pours, their work will stop.

Zhao Zimeng, Ling Hu Yunfei, Director Zhang, Manager Feng and Captain Xiao walked to the well.

The wellhead is not big, but the space below seems to be not small, and it is getting bigger and bigger the further down, Zhao Zimeng took advantage of the direct light of the engineering lamp to visually measure, the distance between the water surface and the wellhead is at least about three meters.

A worker brought two bamboo poles more than one zhang long.

Captain Xiao took a bamboo pole and stretched it into the well, but it didn't hit the bottom of the well.

Captain Xiao tied the two bamboo poles together again, and then stretched them into the well again, judging from the length of the bamboo poles exposed outside the well, the depth of the well should be about eight meters.

This means that the excavator has to dig at least eight meters to reach the bottom of the well, and the silt beneath this water is not taken into account.

The stones and bricks in the well can be dug up with an excavator, and the water in the well may have to be found in another way.

Captain Xiao sent four people to carry two pumps.

After a while, the electrician set up two triangular brackets on the north and south sides, added two engineering lights, and when the switch was turned on, four high-wattage lamps illuminated the scene as if it were day.

The light illuminates both the well and the water in the well, as well as the expectant faces.

Maybe it's because they've been busy for a long time, but under the strong light, everyone's faces look very pale, and their expressions are a little dignified.

After a while, four workers arrived carrying two pumps on flat poles. The crowd stepped back again, out of the way.

Two workers placed a pump on the west side of the wellhead, put one pipe into the well, and put the other pipe into a deep ditch on the west side of the well.

The other two workers put a water pump on the east side of the wellhead, put a water pipe into the well, and put the other water pipe into the deep ditch on the east side of the well hall, the location of the deep ditch is behind the courtyard of No. 115 and No. 116, No. 116 is the old house of Cao Runan's family, and No. 115 is the old house of a family surnamed Zhang.

No. 117 is the only house near the foot of the mountain in this nostalgic village. In the opinion of Professor Nie and Professor Jin, the two deep ditches in the east and west of No. 117 are likely to be the earliest drainage ditches in the mausoleum.

The electrician plugged in the power supply, the pump worked, and with a "bumpy" rumbling noise, the water in the well quickly rushed out of the nozzle of the drain pipe.

Half an hour later, the well was drained. Zhao Zimeng clearly saw that there were bricks, stones and broken tiles at the bottom of the well.

Bulldozers and excavators demolished houses earlier, and a small number of bricks and tiles may have fallen into the well at that time.

Uncle Cao said that when and after the people moved out, there were naughty children who threw bricks and stones into the well from time to time to play.

According to Captain Xiao's request, the excavator first started digging from the periphery of the well, and after digging to a certain depth, it pushed the wall of the well to the outside to try not to let soil and bricks fall into the well.

The wall of this well is unusual, it is made of 60 centimeters of square bricks. No wonder this well has been used for so many years.

In order to prevent the pit wall from collapsing, the pit mouth was dug very large at the beginning, more than twice the size of the well hall.

Because the well is too deep, the mouth of the pit must be dug larger, so that the soil on the edge of the pit will not roll down.

The excavator piles the excavated soil on the outside of the pit mouth, and at the same time rolls the excavated soil, so that the cycle is repeated, layer by layer.

Captain Xiao is an anxious man, he saw that the progress was relatively slow, and transferred an excavator with a longer arm span, two excavators on one side, and soon, finally dug to the bottom of the well.

Captain Xiao is also a person who understands, he knows that the excavator can only dig the soil around the well, not the bricks, stones and silt at the bottom of the well.

Therefore, he took two workers to the side of the well wall all the way, fishing up the bricks, stones and tiles at the bottom of the well one by one, but the process was very hard.

Zhao Zimeng and Ling Hu Yunfei also went down to the bottom of the well.

After the bricks, stones, and tiles were removed, the bottom of the well was left with black silt.

Next, the five men searched for something in the mud.

A worker fished out a kitchen knife, a pair of scissors, and an iron hook from the mud; Another worker fished up an iron bucket.

"This bucket belongs to my family, a year ago, when I was fetching water, the rope broke, and the bucket fell into the well." Sister-in-law Che shouted in surprise.

"The scissors seem to belong to my family, and once after I killed the eel, I put the scissors in a wooden barrel, and my grandson was naughty and had to use the wooden barrel to fetch water, and he ended up getting the scissors into the well. Uncle Cao said.

The kitchen knife is indeed unrecognized, is this kitchen knife the one that the murderer cut off the first head? If so, then it is possible that the knife was dropped by Mr. Cai when he moved.

The handle of the kitchen knife is made of wood, the wood has cracked, and there are three circles of vermicelli-thick wire wrapped around it, and the handle is still a little shaky.

The blade is about 30 centimeters long, narrow in front and wide in the back, about 15 centimeters at the widest point, about 13 centimeters at the narrowest point, the thickness of the back of the knife is about 0.3 centimeters, there are two gaps on the knife edge, the large gap is about 0.5 centimeters deep, and the small gap is about 0.3 centimeters deep.

The blade wasn't rusty, and it should have recently fallen into—or thrown into a well.

Captain Xiao found two wires under the mud - the kind of wires that were plastic-wrapped with copper wires.

He tugged at one end of the wire, only to pull up a somewhat heavy stone. If you look closely, you can see that the wires are wrapped around the stone.

Captain Xiao lifted the stone with all his might.

"Captain Xiao, slow down, something has fallen from under the stone." Linghu Yunfei said suddenly.

When Captain Xiao was lifting the stone, the other end of the wire was suddenly straightened.

Zhao Zimeng walked up to Captain Xiao, half-squatting, bending down and bowing his head.

He saw that there seemed to be a round thing underneath the stone.

Ling Hu Yunfei exclaimed: "Team Zhao, it seems to be a human head. ”

One stone stirred up a thousand waves, and this sentence quickly exploded in the crowd, and the crowd began to stir.

The stone and the round thing were covered with black silt, and it was impossible to determine whether or not there was a human head underneath the stone.

Zhao Zimeng already had the answer in his heart at this time, and he had a keen sense of smell and smelled a special smell: it was the smell of the smell of silt mixed with the smell of soft tissue decay - Zhao Zimeng had been engaged in criminal investigation work for many years, and he was too sensitive and familiar with this smell.

Zhao Zimeng was even more sure of the idea just now: after the murderer cut off the head of the deceased and left the scene, he threw his head into the well, which is very likely.

The well will eventually be filled, and even if the foundation is dug, it will not be dug below eight meters. What's more, in the developer's original plan, No. 117 and this well were not planned at all, and it was only possible that it would be razed to the ground.

Captain Xiao hugged the stone, Zhao Zimeng took the shovel from the hand of a worker, picked up the spherical object from the silt, and the two of them walked to the flat ground next to the excavator - here it had just been crushed by the excavator's tracks.

The length of the wire between the stone and the sphere is six or seven centimeters - two wires.

Captain Xiao put the stone on the flat ground, Zhao Zimeng slowly put the shovel on the flat ground, and when Zhao Zimeng tilted the head of the shovel, the spherical body suddenly turned over, and then fell on the flat ground.

At this time, Zhao Zimeng and Ling Hu Yunfei saw clearly that the bottom of the spheroid body was actually a columnar body.

Zhao Zimeng gently flicked the spherical body with a wooden stick, and the spheroid was soft.

Ling Hu Yunfei aimed the pillar of light of the lamp at the round object, and it did look like a head.

The upper part is the globular, and the lower part is the columnar body, which should be the head and the columnar body should be the neck. Zhao Zimeng and Ling Hu Yunfei had just conducted an autopsy on the No. 1 corpse.

The incision in the deceased's neck was almost at shoulder level, so the part of the neck attached to the head should be long, so that it resembles the shape of the object in front of him.

Zhao Zimeng carefully removed some of the mud from the spherical object with a wooden stick, and found that there were several loops of wires wrapped around the spherical object, and several loops of wires were also wound around the stone, and they were connected side by side with two other wires.

"Team Zhao, this is already very obvious, it's a head." Ling Hu Yunfei said with great certainty.

Zhao Zimeng nodded—he thought so too.

Ling Hu Yunfei stood up: "Captain Xiao, can you get some water?" ”

"We've only been in the field for a few days, and the water hasn't been connected yet, so I've just sent someone to get two buckets of water from a nearby resident's house – wait a little bit, the water will be there in a while." Manager Xiao said.

At this time, it was time for dinner, but the onlookers were in high spirits and did not have the slightest intention of dispersing, but gathered more and more, and there was a large group of people standing outside the cordon.
