Xiaokong looked at the two deputy factory directors and asked with puzzled eyes, "How do you know!" ”

"It's very simple, you see that there are no two traces of disappearance on the inner wall of the silo, and there are a few not very obvious shoe prints around, although they have been carefully erased or concentrated together, but the metal runner moving under the silo has obviously disappeared a piece, only when someone scares the silo, will step on such traces, and under normal circumstances, it is impossible to remove the material stains on the runner." Lao Xing pointed to the runner and inner wall of the silo and explained to a few people.

From the outside, the silo looks like a lot of space, but standing in front of the silo opening, you find space for up to two adults, and the runner at the bottom is very thin and deflection, rotating and winding to connect the unloading port.

Yan Mo roughly estimated the height of the silo, which was more than 2 meters high, if it was not very tall for an adult, it would not be easy to go down to the silo, and the footprints that appeared on the ground in the centrifuge room seemed to have a reasonable explanation.

It must be a person hiding in the silo, the height should be 1.75 meters above, and the patience and physical strength are amazing, the shoe prints that appear on the ground are roughly what he came out of the silo and stepped on the ground, from which Yan Mo also deduced that this person must be a man, and the shoes he was wearing should be a kind of labor protection shoes, because only the shoes of labor protection products can hide in the silo for a long time.

Yan Mo looked at the general silo cover that should be welded by electric welding on the silo, there were many white material stains on it, roughly as fine as dust, a thin layer hung on the silo cover, and several dead corners that were not easy to see attracted Yan Mo's attention, Yan Mo took the traces on the inner wall of the silo with a camera prepared in advance, and handed it to Deputy Director Li.

Looking at Yan Mo's eagerness to try to get out of the silo, everyone showed puzzled expressions, Xiaokong just wanted to ask Yan Mo, but when he saw Yan Mo's serious face, he didn't step forward to stop his move, just walked into the front of the silo, and gave Yan Mo a look to pay attention to safety.

Yan Mo slowly stepped on the inner wall of the silo with half a foot sideways, holding the top of the thick inner wall above the silo with both hands, and after stepping on the inner wall with both feet, he slowly slid down, and after stepping on the gap between the slices with extreme care, he slowly let go of his hands, tried to turn around, squatted down and looked at a few dead corners, and the blocked area.

After Yan Mo stabilized his body, he asked Deputy Director Li for the camera, and after taking it, he leaned against the inner wall of the silo, and took pictures of several palm prints and indentations he found with the camera in both hands.

Yan Mo checked back and forth in the silo a few times, and found that there was nothing valuable, so he had no choice but to throw the camera away, and he crawled out of the silo with great difficulty, and when Yan Mo came out, his body was already full of a lot of white powder, and Yu Mo looked at the shoe prints on the ground again, and suddenly remembered, what kind of mentality made the people who came out of the silo disappear after leaving footprints on the ground?

Without dealing with the white powder on his body, Yan Mo stared at the shoe prints on the ground, followed the footsteps, looked back and forth without taking a single step, and then walked forward, and when he walked to a small lounge in the centrifugal room, Yan Mo suddenly understood that the reason for the disappeared footprints was because after stepping on the ground, the white powder stained on the soles of the shoes was trampled on the ground, which led to the disappearance of the shoe prints.

And this point has brought trouble to Yan Mo and them, why? Because at first, everyone thought that the owner of the shoe print left in the direction where the shoe print disappeared, but in this way, the back door in the centrifuge room can also be used to provide people to leave.

Yan Mo walked to the door of the small lounge in the centrifuge room, looked back at his footprints, and Yan Mo felt a very strange feeling! What is it? Yan Mo couldn't notice it.

At this time, the other people had already followed, and Ambiguous Jie and Xiaokong were the last to come to Yan Mo's side, Yan Mo turned his senses and shook his body, and a lot of white medicinal powder fell from the hat of Yan Mo's clean clothes and landed at Yan Mo's feet.

Xiaokong and Ambiguous Jie, who came to Yan Mo's side, glanced at each other, Xiaokong smiled at Yan Mo, and asked expectantly, "Did you find anything?" ”

"I think the deceased should have been killed in this lounge, and then slowly hoisted into the air, only in terms of wireless controllers, I probably have a conjecture, but only when the murderer is confirmed can I determine whether this is the case, and once my conjecture is wrong, then the murderer is through other means!"

"So, do you think there's anything strange here?" Yan Mo always felt that his intuition was right, but he still couldn't think of what went wrong, "The two doors in the front and back of the centrifuge room are normal!" The most unusual thing is that there are two large security gates here! ”

Ambiguous Jie pointed to the two safety doors that were located on the left side of the centrifugal lounge and opposite the centrifugal rest, which was Lao Xing hurriedly explained, "Each safety door corresponds to a passage out of the centrifugal room, which is prepared to prevent emergency accidents, and there is a metal hammer next to each safety door, which is used by the staff to escape when an accident occurs!" ”

Yan Mo still knows a lot about the role and placement of the security door, just when Yan Mo raised his head after listening to their conversation, and his eyes extended to the security door he was facing him, a thunderbolt flashed in Yan Mo's ears, which made him understand a little!

"If I'm not mistaken, the task of Ge Lao that night shift is to clean up the equipment, and there are no staff members in his nearby post, only he works alone, and there are only a few employees in this building at most, am I right!?" Yan Mo looked at Lao Xing confidently.

"That's right, we need to clear the site here, so he and three other employees are the only employees who go to work, and I am left with some old employees, but there is still a certain distance between the separate positions. How do you know? ”

"Footprints!" Yan Mo pointed to the footprints on the ground, "Do you think, if there are people in the post where the two security doors are connected, who will swagger out of the silo and walk to the centrifugal lounge, if someone goes to work, he will definitely turn around and observe, and the footsteps will be much messier!" Yan Mo smiled lightly, and then said generously and forcefully: "I conclude that the deceased who hid in the silo must know that he is inside!" Then he can walk here unscrupulously without fear of being afraid that others will see it. ”
