A concrete mixer is a machine that mixes cement, sand and gravel aggregates and water into a concrete mixture. It is mainly composed of mixing drum, feeding and unloading mechanism, water supply system, transmission mechanism and supporting device. Engineering students studying civil engineering have some understanding of this field, but most people have no understanding of this field. Even Ye Qidong, who has worked in the police task force, theoretically does not know much about this field. "How do you know it's a 350-type machine?" I couldn't help asking every time. "That's what it says!" Ye Qidong said coolly. Following his line of sight every time, he found a white graffiti on the right side of the mixing drum of the mixer, with the words "Type 350" written on it. He smiled awkwardly every time, and Ye Qidong said lukewarmly: "About three years ago, I received a case where a mixer on a construction site had a problem and a life was lost. At that time, I did some investigations in the task force. I This person has always had a good memory. He usually never forgets any report he compiled. " Li Tui was slightly startled. Ye Qidong brought up the mixer case inexplicably. This may be a hint from the Lord God. If a plot character who is not good at words takes the initiative to bring up a certain topic, then it is very likely that this topic is inextricably related to this task. ¡¾Blender. ¡¿ ¡¾Murder case. ] "This kind of machinewell, it's a little more powerful than the one here" Ye Qidong lay on Li Tui's back and looked sideways at a pure green blender on the other side. It was an old-fashioned self-falling mixer. It looked like a cannon with its muzzle pointed forward and upward. There were two wheels underneath, which could push the rotating shaft to change the aiming direction of the "muzzle". He looked back at the large round tank marked 350. It looked like a giant soymilk machine, with the mouth of the basin facing upwards and some rust all over. Although the power was turned on at the moment, no one was filling it with material, and no one was filling it. People have time to pull the switch. "Compared with the self-falling mixer, the circular groove horizontal shaft forced mixer is more efficient. It is divided into single horizontal shaft type and double horizontal shaft type. It has the characteristics of both self-falling and forced mixing. The linear speed of the mixing blade Very small, um, haven¡¯t you forgotten about high school physics? You know the meaning of linear speed. This kind of machine has good wear resistance and fast development. You see, the rotating shaft arm is equipped with mixing blades, and the materials in the mixing drum are mixed. Under the strong stirring of the blades, a cross flow is formed. This mixing method is much stronger than the self-falling mixing method, and is mainly suitable for mixing dry hard concrete. " "Well, okay, you know a lot, butit seems like this. It won¡¯t be of any help to us.¡± I couldn¡¯t help but look at him with disdain. Even though this plot character is cold-tempered, he seems to be a bit pedantic in his conversation. "Isn't it just that I read some books in the police station? I will read fewer books in the main god space than you? It's just that the fields we study are different." Cidu thought to himself. Li Tui said nothing. Feeling that most of the pursuers at the rear had stopped, Li Tui became more and more sure of his previous thoughts. "It seems that we have indeed entered an area that we should not set foot in!" "I feel the same way. I think the word 'forbidden area' is not an exaggeration to describe it." Lin Siyu couldn't help but look back, and the data from the outside world Hundreds of people formed an arc to guard the construction area, but no one attempted to take a step forward. They stood in the distance and watched Li Tui's every move with their breaths. There was a surprising tacit understanding, and their hisses and curses were heard from the beginning to the end. Didn't pop up a few times. "It's the cable. It should be like this. We rushed here in too much haste." Li Tui put Ye Qidong down and handed it to Lin Siyu. He lowered his head and looked back at the road. As expected, there were scattered some trampled objects in the nearby area. There are dirty cables. On the surface, these cables seem to be irregular, and some of them are even stepped on the soil. However, if you look closely, you can find that this is actually a technique of drawing the ground to form a prison. Some thoughtful people deliberately drew a winding cordon in this work area to warn workers on the entire construction site not to cross the line even half a step. ¡¾Is someone going to die again? ¡¿ "Someone is going to die again!" Li Tui whispered to himself, and Ye Qidong said the same thing almost at the same time. ¡¾Hehe, he can indeed read lips. ¡¿ Both of them turned their attention to a contractor wearing a yellow safety helmet in the distance. His hat was a different color from the others. His skin was dark and he was older. At first glance, he looked like the kind of old man on the construction site who could control people. Be cautious and have strong leadership skills. He looked at Li Tui from a distance and murmured softly: "Someone is going to die again!" He happened to be seen by Ye Qidong and Li Tui who could read lips at the same time. "Compared to Ye Qidong's lip-reading skills, Li Tui's level can only be regarded as amateur"? The reason is simple. Li Tui can only read Mandarin Chinese and English with American or British pronunciation. Ye Qidong is not only proficient in Mandarin, but also proficient in various dialects in Taiwan. Most of the workers entering the construction site are migrant workers, coming from various cities, and many of them speak fluent dialects. Previously, Li Tui heard a big man shouting to a small man: "Don't rush so far forward, you are so thin, don't be so ging!" The word "ging" is a dialect, and Li Tui didn't understand what it meant at all. But based on the context, it can be roughly deduced that "don't be so ginger" should mean "don't show off" and "don't hold on". "Be careful, there are a lot of mechanical equipment here, and they are all plugged in!" Li Tui and Ci both supported Ye Qidong step by step. "Well. You should also pay attention to yourself. Don't go so far forward." Lin Siyu said with concern. "By the way, Mr. Ye, how long will the effect of your spray last? How many sprays do you still have on your body now?" Li Tui asked in a low voice. "The last spray is used up. This kind of thing will evaporate if it is not used for a long time. Hashimoto didn't leave much for me. I used up the last half of the bottle in two times. Now, it is estimated that it can still last for half an hour." Ye Qidong kept looking around as he spoke, and his eyes finally settled on the chests of several people present. He squatted down, picked up a wooden stick and drew it on the ground. He took the lead in drawing an umbrella-shaped distribution map. While drawing, he explained: "Now without me, all four people are connected to the wire. The entire construction site, except for Four of us were connected, and I only saw three people being connected, so meeting you at such a huge construction site is not fate, but an inevitable event!¡± ¡°Most of the weird things that appear in Taiwan now are big ones. The scale is turbulent. This time it is a large network! We count four terminals. So, where is the server?" This time he gave a vivid metaphor for the current symptoms. "This is my headache. I will tell you? The server is not on the same level as us?" Ye Qidong frowned slightly. "In the sky?" Citu asked in a nonchalant manner. Li Tui interrupted on the spot: "Didn't I say before that Cui Yongkang visited the underground work area once? It's really inconvenient to get down to that kind of place. So, the terminals of the four silk threads should be in the underground world!" "Since it is in the underground world! Underground, the effect of the medicine in your eyes has not disappeared, we should easily find the server!" Lin Siyu pursed her lips. Ye Qidong continued to lift the wooden strips, extending several slender lines at the gathering point of the umbrella-shaped figure. He suddenly felt erratic, then raised his head and smiled bitterly: "I guess you haven't personally experienced the silk incident, right? I went there I have been linked by a thread, and my girlfriend has also been linked. I have spent a lot of time tracking down the thread. They are more complicated than you think. Don't think that you can find the source by following the thread. An irregularly moving energy body? We are really helpless." Li Tui took a deep breath and bit his fist: "The other end of the strange thread you encountered was a regularly moving energy body, so you based your judgment on it. You found the ghost you wanted to track and saved your girlfriend. "So, this No. 2 is also moving?" "No. 2?" Ye Qidong looked at Citu with a puzzled look. "Ah" Um, this this" Cidu cast a look at Li Tui asking for instructions. "We have discovered two spooky thread incidents in Taipei so far, and numbered the corresponding ghosts. Last time it was No. 1, and this time it is No. 2. As for the Death Crossing incident you mentioned, we have designated it as No. 3." Li pushed quickly He explained Ye Qidong's question carefully, and he was more concerned about Ye Qidong's subsequent analysis. "Oh, is that so?" Ye Qidong wasn't very interested in the past of people like Li Tui. Just like when he joined Hashimoto's research group, he didn't ask too many unnecessary questions. He was used to doing his job well. Ye Qidong led Li Tui and his group to stand in a shady area with the back of the sun. He squatted down and continued to immerse himself in drawing. While drawing, he explained: "Now that the four of us are together, where the sun is not bright enough, I can see four treacherous streaks." Si Tongtong is connected to a certain direction in the distance, but the distance is too far, and it is difficult to estimate the specific location of the ghost with the naked eye, and it rarely moves on the road today. He mostly wanders in the underground world, and the speed of movement You don¡¯t need me to say it, you all know it.¡± ¡°So, this is a difficult problem that the Lord God has given us! If you are wandering in the air or moving on the ground, you can still find clues no matter how difficult it is. But it is really difficult to capture the ghost that travels freely underground. Unless you dig three feet into the ground or have clairvoyance. ] "But it shouldn't be as difficult as we expected." Lin Siyu suddenly said: "It's not that, except for me,Besides the four of us, did you see three other treacherous threads? " "Yes, that is the number I noticed along the way. The real number may be more. It is not yet certain how many terminals are connected to the server. I can only conclude that there are only four in our direction! Even if there is one more one, with some differences in angle and direction, it will be of great help to us in tracking the server. "Hey, wait a minute" As he spoke, Ye Qidong suddenly raised his head excitedly, pointed at a piece of air and shouted: "There is an extra line in that direction!" " "oh? Looking at it from another angle and estimating its length, I feel that it should extend beyond this forbidden area. "Cidu also became excited. However, Ye Qidong suddenly sat down. "What's wrong? Lin Siyu asked softly. "No need!" It must be broken! "Li Tui replied coldly for Ye Qidong: "Someone died! "
