Into Unscientific

  Chapter 71 further expanded situation (explosive update starts today!)

  Generally speaking, there are usually two forms of use of pyridacloprid:

  Intermediate powder and gel bait.

   Among them, intermediate powders are mostly used in the agricultural field, with large quantities and wide coverage, but the insecticidal efficiency per unit volume is relatively limited.

  After all, the efficiency and cost of insecticide are directly linked. The four words of the agricultural field are actually cultivated land or fruit forests, ranging from two or three acres to hundreds of acres.

  If it is true to buy that kind of high-efficiency insecticide, the income of the farmers will not be enough for spraying.

  In addition to the intermediate powder, most of the commonly used pyridacloprid in the daily life are gel baits, that is, high-specification and high-concentration polymeric insecticides.

  For example, Bayer's Baimishi, in theory, kills more than 50 cockroaches with 0.2 grams.

  This is true for the third-generation pyridacloprid, let alone the fifth-generation pyridacloprid developed by Xu Yun and the others.

  150 ml of water is 150 grams, and the density of the fifth-generation pyridacloprid gel bait is much higher than that of water. The gel bait contained in two 150 ml syringes adds up to about 700 grams, that is, seven taels per tube.

  This amount of glue bait to wipe the wall

  Everyone can simply imagine what the concept is.

   More critically, since HKUST is located in downtown Luzhou, the drainage facilities of the entire campus must be distributed from the inside to the outside.

   Among them, Building No. 14, located on the edge of the East District, is a large-scale outlet node that gathers multiple sewage pipes in the school, and the number of cockroaches around it is several times higher than that in other areas.

   Therefore, the seriousness of the whole situation is far higher than what Chang Licheng saw in the dormitory.

  When Xu Yun arrived at Building 14, the entire dormitory was surrounded by a large number of onlookers who came from nearby dormitories, and they kept an effective distance of 30 to 40 meters from Building 14 in a tacit understanding.

   "Excuse me, I'm Yingwu's teaching assistant, thank you."

  Xu Yun got out of the crowd of onlookers with some difficulty, and saw that at this time the center of the venue—that is, the open space outside the gate of the dormitory building, were standing several dormitory managers and inspectors who came on duty at night.

  Through the bright flashlights in their hands, they can vaguely see an extremely scary scene:

   Students who have lived in dormitories should know this.

  Each dormitory building usually has three to five white sewer pipes with a diameter of about 15 centimeters outside, depending on the scale of the building. Most of them are located between the walls where two dormitories meet.

   At this moment, there are countless cockroaches slowly climbing along the outer walls of several sewer pipes from bottom to top.

   Then turn left on the third floor and climb to the fourth floor through a window at the corner of a staircase

  The rest simply poured in from the gate on the first floor, rushing densely to the fourth floor.

  Of course, there must be something in and out.

  For example, some cockroaches have been poisoned and entered a hyperactive state, with their wings spread high, and they flew out of the window, followed by a large group of the same sex.

  Under the night sky, the onlookers outside seemed to be Cao Cao's army back then, and they were stopped at Dangyang Bridge by Cockroach Fei.

  Mixed in this scary scene were the closed doors and windows of the dormitories, as well as bursts of strange screams from time to time.

  See this scenario.

  Even the night patrol team of the University of Science and Technology with more than ten years of security experience, you look at me and I look at you, standing in a daze with a flashlight, looking dazed and at a loss.

  The elder sister in charge of the dormitory at the side has sharp eyes, and her eyes swept across Xu Yun who had managed to get out of the crowd, and her expression was overjoyed:

   "Assistant Xu, you're here too? Come and see, what's going on here?"

  Xu Yun walked up to them with a wry smile, and looked up at the densely packed cockroaches:

   "Sister Liu, how long has this situation been going on?"

  Sister Liu is a middle-aged woman with a bloated figure. She and her husband have been housekeepers for more than ten years. Hearing this, she also looks puzzled and scared:

   "I don't know either. At that time, I was still cooking for the boys in 203. I heard a strange noise from somewhere, and then I saw a bunch of cockroaches running upstairs. That's the situation."

Open flames are prohibited in the dormitories of the University of Science and Technology, so some dormitory managers will prepare some side dishes such as chicken offal on weekdays. If students want to drink some beer in the dormitory on weekends, they can order a plate or two at a very affordable price. A little extra money.

   It turned out that Sister Liu was continuing her private work. When she realized something was wrong, she quickly turned off the stove and ran out with her husband.

  Xu Yun couldn't help sighing when he heard the words:

   "Sister Liu, have you contacted the school leaders?"

   "I just made a phone call with several counselors and the leaders of the branch of the hospital. Dean Tian is on his way here."

   "Dean Tian? Has he not rested yet?"

   "No, he said he was doing some experiments, and when he heard the news, he told me that he would be on the scene soon, and that he didn't need to call the fire brigade"

  Xu Yun couldn't help feeling relieved when he heard this.

  Looking at the entire University of Science and Technology, except for Qiu Sheng and several members of the research group, the only one who can guess the inside story in a short time, aside from Xu Yun himself, is Tian Liangwei.

  If you change to another school leader or even the school leader, what big trouble will happen if you don't keep the same.

Those with a relatively stable mentality may be able to deal with it calmly. If they encounter some emotional leaders, they may make up their minds in the direction of earthquakes or even demonization. After all, most schools are built on cemeteries. In fact, many School leaders are superstitious.

  Basically, among the top ten campus legends of every school, there will be more or less something to do with A Piao.

   Just like that, about twenty minutes passed.

  Tian Liangwei finally rushed to the scene with his assistant.

  As soon as he parted from the crowd and walked outside, Tian Liangwei felt his scalp tingle. Looking at the densely packed cockroaches, his hometown dialect came out:

   "Mother Xipi, there are so many cockroaches? Xiao Xu, what did you do?"

   Xu Yun, who had been waiting here for a long time, sighed quietly, and described the whole process in detail, trying to take the responsibility on himself as much as possible between the lines:

   "That's about it, Director Tian, ​​this is mainly my responsibility, I didn't explain the dosage to Li Cheng and the others."

  Tian Liangwei frowned at the beginning, but as he listened, the expression on his face gradually became a little weird:

   "It's not all your fault, after all, it's a matter of poor information. Those two live treasures probably searched the Internet for pyracloprid for agriculture, and thought that the effect you gave them was just that.

  Forget it, let’s not talk about it, Xiao Xu, is there anything you can do now? "

  Xu Yun was silent for a while, then said:

   "Director Tian, ​​the first thing we need to do is to stabilize our emotions. Just now I have contacted several cadres of the physics department in the dormitory building. After group-to-group and person-to-person notifications, the doors and windows of each dormitory have been closed.

  Now the students in the dormitory are mainly emotionally fluctuating, and the others are not affected much, so more effort is needed to appease the work. "

   After finishing speaking, he paused, and continued:

   "As for the follow-up suggestion, my opinion is... wait!"

"Wait?"

  Xu Yun nodded and said:

   "After all, two tubes of gel bait are obviously excessive in terms of dosage, but that's the case in terms of coverage area.

   If there is no accident, it should have spread to the third generation of receptors by now, and it will almost stop after two more rounds.

  So instead of manual intervention, it is better to just wait on the sidelines, and then spray some disinfectants around to prevent cockroaches from escaping.

  Just like this, the students in the dormitory may have to do a good job of psychological counseling, or should everyone add a 0.2 grade point at the end of the semester? Guaranteed to be alive and kicking tomorrow! "

  Tian Liangwei's mouth twitched a few times:

   ". You made it up yourself, let the school make up the grade points?"

   Then he sighed:

   "Let's talk about the compensation at that time. I'll let you do what you say about the solution. I'll explain it to the college and the school. Good guy, at first I thought it was a biochemical crisis."

   While Xu Yun and others were talking, the Internet gradually became lively.

   Sleep in one breath until five o'clock in the afternoon, you can start liver today! !

   Quadruple monthly tickets begging for a reward, at least until 5:00 am today! !
