Drink Black Tea Calmly at Hogwarts

　　 In Zhang Xu’s previous life, there were often news reports that someone was arrested for placing pinhole cameras in the women’s locker room, the women’s bathhouse, and the women’s bathroom. What Zhang Xu didn't expect was that he himself had one day installing monitoring equipment in the girls' bathroom.

　　 This is not a distortion of human nature, nor a moral decay, nor a sexual outburst, nor hunger and helplessness.

　　 Ever since Zhang Xu found out that Lockhart had picked up Tom Riddle's diary and the wheel of history fell into the gutter, he installed magic equipment for surveillance in the toilet of the crying Myrtle. Since the monitoring equipment cannot transmit signals wirelessly, he has to find time to hide and avoid Myrtle every day, and go to the bathroom to take daily video recordings.

　　 Because Myrtle often makes trouble in the bathroom, except for the occasional one or two girls who can't help it, almost no one will enter this bathroom. Of course, with the exception of the man in the surveillance picture, he sneaked into the girls’ bathroom. After checking that there was no one in every compartment in the bathroom, he walked to a faucet and said to the faucet. Something went wrong, and then jumped into the channel created by the faucet.

　　 Entering April, Zhang Xu found that Lockhart was sneaking into the girls' bathroom more and more frequently, and other preparations were basically completed, so he decided to start working.

　　 Zhang Xu walked into a classroom and greeted two acquaintances who were busy in the classroom: "Fred, George, are you finished?"

　　 "It's ready," George said.

　　 "The installation can start tonight," Fred said.

　　 After everyone in the "tea time after school" learned that the monster in the secret room was a basilisk, they organized a research team to start research on methods to deal with the basilisk. The research team also chose a classroom that has not been used for many years as an office space.

　　 In order to prevent the Slytherin heir from mixing into the research team, the group members are basically Muggle-born wizards and half-blood wizards, as well as the Weasley twin brothers and Zhang Xu who are least likely to be the heirs of Slytherin.

　　 At first, someone asked Zhang Xu if he could buy magic items that could protect the basilisk.

　　 Zhang Xu said that he could not help.

　　 In fact, Zhang Xu has protective items of this level, but they are military-level items, and they are used to save their lives. In the school, except for Zhang Qiu when he is in danger, no one else will give it to Zhang Qiu.

　　 Actually, the iron armor curse amulet sold by Zhang Xu in the school is of the police level. Otherwise, Ginny, who is carrying two amulets, would not be injured by the magic trap in the secret room. On the battlefield, the amulet that can't carry mortars hard and then is okay is meaningless.

　　 The research team’s design approach to armor can only go from “not hurting” to “immortality”.

　　 It is recorded in the book that the eyes of the basilisk are staring at each other. In the several attacks during this school year, two people and a cat indirectly saw the eyes of the basilisk, and then they were petrified.

　　 At the suggestion of Zhang Xu, the research team made a kind of goggles based on the principle of Colin's camera. After passing through the reflection of the four groups of lenses in the goggles, the light passes through a path similar to "_Π_" before reaching the wearer's eyes. Before and after the goggles, several layers of magic crystals are also set up, giving the goggles the functions of a telescope and night vision device.

　　 Although the goggles have not been tested in practice, since Colin is not dead, it is theoretically feasible.

　　 After the goggles were developed, the president of the student union who had also participated in the "tea time after school" brought the goggles to Dumbledore. After a while, he got the funding for making 70 pairs of goggles.

　　 The problem of armor is solved, and the problem of offensive weapons is better solved.

　　 Although everyone took a detour at the beginning and tried to use the magic items of the Great Crisis as weapons, these things were not something that the students could solve.

　　Hermione said that she could get a batch of guns through her father, and the other Muggle-born wizards in the group were alive.

　　 In the end, Hermione’s idea of ​​destroying the style of painting was pushed down by Zhang Xu in a cold sweat.

　　 Others don't know the skin of a basilisk, he does. When he wanted to peel it back then, it took the boss's effort and it didn't happen. When taking bile, venom and snake blood with a syringe, the special needle also took a lot of effort to get in.

　　 For this kind of snake skin, the power of the pistol bullet is not enough, but there is a danger of ricocheting others by accident. Even if the pistol can break the defense, how much the pistol bullet can stop the basilisk is still a question. When Zhang Xu was a child, he had seen cows in the countryside go crazy. The 54-type of the police at the police station hit the mad cow several times, but failed to reach the point. As a result, the injured mad cow became even more mad. In the end, Zhang Xu's grandfather took the shot and fainted. Mad cow. As for the Desert Eagle, the recoil was enough to injure the hand of an untrained student after one shot.

　　 If it is an automatic rifle, the power is enough, but if Mr. Granger gets a batch of automatic rifles, not only the style is wrong, it is also dangerous to Mr. Granger.

　　 In the end, Zhang Xu could only point to the line "The Basilisk can only run away when he hears the rooster's crow, because the rooster's crow is also fatal to it" in the book, twisting everyone's mind.

　　 The cock's cry is simple, and there are many students who can make a rooster by using polymorphism in Hogwarts. And anyone can get magic items that can be recorded. And there is another big killer in Hogwarts Castle, the cable broadcasting system. If you play the rooster's roar throughout the castle through the big horns in the castle, you can basically lie down and win ~www.readwn.com~ Then Zhang Xu will work on the early warning system with everyone.

　　The early warning system finally chose the most practical solution.

　　 Next to the loudspeaker in the corridor, put a cage with white mice in it. Then set the magic, when the mouse in the cage loses life because of seeing the eyes of the basilisk, the big horn starts to play the rooster's cries. The guinea pigs can be raised by the house elves at Hogwarts.

　　 The president of the student union found Dumbledore again with this plan, and after some fooling around, he returned with the funds.

　　 Just tonight, the Weasley twin brothers will take the house elves to install this early warning system.

　　 After greeted the twins, Zhang Xu walked aside and watched as the other team members were discussing how to deal with the basilisk tactics.

　　 Since this time, everyone has organized a team of about 60 people with the members of the "tea time after school" as the backbone to deal with emergencies about the basilisk. For example, covering students to retreat, defending for aid, and concentrating on destroying basilisk.

　　 When the team was first formed, we only selected students above the fourth grade and formed a group of 50 people. In the whole group, only Zhang Xu was below the third grade.

　　 Later, Zhang Xu used the Hogwarts spirit to be passed on from generation to generation, and tried to outsmart the crowd and brought in a dozen junior students from the four colleges including Harry's trio in the name of an auxiliary team.

　　 Although others were puzzled, they finally agreed to Zhang Xu's approach.

　　 In Zhang Xu's heart at the time, if he didn't bring Harry Potter to play with, these people would be found by Dumbledore to have tea and talk.

　　 After listening to the group members' discussion for a while, Zhang Xu saw that the time was almost up, so he found Hermione and took her to the kitchen.
