Soon after, Yan Mo drove to the pharmaceutical factory in Xixi.

After parking the car in the parking lot of the pharmaceutical factory, Lao Xing and Lao Li took the three of them to the office building, Yan Mo glanced at the factory building at Xiaokong, Xiaokong understood what Yan Mo meant, and went directly to the factory.

Xiaokong hurriedly said to the two deputy factory chiefs, Xing and Lao Li, "Let's go to the factory where the crime occurred first!" Lao Xing smiled, and then explained to Xiaokong, "I went upstairs to get the key to the factory, since the accident, I have temporarily let them go back to rest for the production work there, and it is considered a paid break, so as to dispel their worries, after all, we once let them go back to vacation when the pharmaceutical factory closed, and then there was no notice to go to work until our factory was reopened." After Lao Xing finished speaking, he looked at the surrounding factories desolately, smiled reluctantly at a few people, and went upstairs to get the key.

Xiaokong didn't wait downstairs, walked to the side of the building where the incident occurred, walked around the building, and silently counted how many entrances and exits there were in the building as he walked, and how many windows there were on the floor where the incident occurred.

When he was about to go around for a week, Lao Xing had already brought the key from the office building, Lao Xing opened a nearby door, and several people walked in.

The centrifuge room is located on the third floor of this building, and the door that Mo and Xiaokong enter is one of the four roads leading to the third floor, and the other roads are connected to the back door of the centrifuge room, which is generally closed and cannot enter the centrifuge room.

After entering the first floor, a sultry and humid smell with a slightly pungent smell poured into everyone's noses, so that everyone couldn't help but cover their mouths and noses, and forced them to breathe as little as possible.

Lao Xing hurriedly rushed into the first floor, Yan Mo ran in, Lao Xing came to the vicinity of a distribution box, turned on the switch of the power switch, and then pressed the open button of the fan and air conditioner on the dashboard, and after a while, I heard the sound of the fan and air conditioner running, and in less than 2 minutes, I felt that the concentration of the pungent and unpleasant smell in the building was reduced, and the damp smell was gradually replaced by cool and dry.

Lao Xing and Yan Mo returned to the door, Xiaokong and Yan Mo had also changed into clean clothes, and Yu Jie also went to the women's locker room to change clothes.

Yan Mo also took clean clothes from the men's locker room and put them on, put on white gauze gloves, and also put on a mask on his mouth, only revealing two distinct eyes, and several people walked into the buffer room, and Ambiguous Jie was already waiting for them in the buffer room.

Along the stairs, several people passed the packaging area on the first floor, the drying area on the second floor, and then came to the centrifugal area on the third floor.

After opening the two sealed doors that play a buffer role, the five people entered the centrifuge room, and what they saw was a whole row of centrifuges, the centrifuges were arranged in a short and fat order, there were as many as 6 units, and because the pipeline behind the centrifuge was not connected in series, so only three units could be used at the same time for each use, and there was a crane suspended high on the left and right sides of the centrifuge, and the wireless controller that Mo and Xiaokong suspected and had problems was also placed on the side of the centrifuge that entered the door.

Yan Mo looked at the rows of footprints on the ground that were arranged in a disorderly manner, so he had to go around the wall to the centrifuge and take the wireless controller, walk to Xiaokong's side and hand it to Xiaokong.

Xiaokong took the wireless controller that Yan Mo handed to him, and looked at it back and forth, it was marked with the word 'West' with a day-shift pen, and there were four square keys on it, and there were two circular keys, and the square keys were written, 'up and down, left and right', and the round keys were not marked with anything, but a big key was indeed the key to the wireless controller, because they were the reset keys of the failure!

Xiaokong knew that the wireless controller in his hand belonged to the crane in the west, and saw that the crane in the west was not far in front of him, hanging at a height of 2 to 2.5 meters above the ground, Xiaokong tried to press the rise button, but the crane did not respond.

Xiaokong pressed the large circular key on the wireless controller, reversed the small circular key, reset the crane, and then pressed the rising key again, this time the crane just slowly rose up according to Xiaokong, pressed the other keys, the crane moved according to the normal instructions, and after Xiaokong tried a few times, it was handed back to Yan Mo.

Xiaokong then asked Lao Xing, "Under what circumstances will the controller be reset?" Lao Xing thought for a while, "Generally, the crane suddenly fast-forward or stops, and when the suspension swings badly, the others are some unexpected failures!" ”

"So, when the police put down the body of the deceased, the wireless controller of the crane can be used normally!?" Lao Xing replied: "Yes, I was at the scene at the time, watching the police personnel operate the wireless controller and put Lao Ge down!" ”

"And where's the controller for the other crane?" Sora began to suspect that his crane controller was being used in confusion, so he lifted the crane up. "It's the same next to the centrifuge, or it's on the centrifuge, remember the last time the police put the two wireless controllers together!" Lao Xing came to the centrifuge according to Yan Mo's method, and saw that there was no centrifuge underground, so he bypassed the centrifuge and took out a crane controller from the side where everyone's view was blocked.

Lao Xing tried to start the crane, the crane can operate normally, and although the word 'east' on the wireless controller is blurry, it can still be recognized!

At this time, Yan Mo began to collect shoe prints, and Ambiguous Jie was held by Xiaokong with a large amount of everything in the centrifugal room, a door that was not big or small, and people needed to bend down to pass through and the blanking silo connected to the second floor attracted Ambiguous Jie's attention.

Yan Mo, who had collected the shoe prints, walked up to Xiaokong and nodded to Xiaokong, "You can go in!" Xiaokong pulled up Ambiguous Jie, smiled at Yan Mo, and walked towards the central area of the centrifuge chamber, while Ambiguous Jie ran on the platform of the silo curiously, looking at the metal lid on the silo in confusion.

Yan Mo followed behind Ambiguous Jie, opened the lids of the two silos, everything was normal in the west silo, but a lot of fine powder had been accumulated, and when Ambiguous Jie ran to the east silo, a suspicious voice came from her side, "Huh? Why is there still two erased marks on the side of the silo! ”

Xiaokong was checking in front of the centrifuge, and the two deputy factory directors also followed behind Xiaokong, but Yan Mo ran to the east silo for the first time, looking at Ambiguous Jie pointing to the disappeared material dust traces on the inner wall of the silo.

Yan Mo frowned, and hurriedly shouted Xiaokong to come up to check, for Yan Mo and Xiaokong, who had no experience in chemical industry, of course, it was just strange that there were many traces inside the silo, but the two deputy factory directors were experienced, and they only glanced at the inner wall of the silo, and the two of them said in unison: "Someone has gone down in the silo!" ”
