Yu Xin cursed Xia Yu's eighteenth generation ancestor while modifying the test paper that had been drawn a lot, many places because of repeated corrections, if you use a little more force, the test paper will be damaged, so she has to be very careful, which has increased her time, more than four hundred copies, that is, normal to change, she is far from being as terrible as Xia Yu, not to mention the current situation, I don't know how many years and months I have to change, now she is not in the mood to be angry, but she wants to cry......

Now I can only hope that Xia Yu will be deflated and recover a little interest in the area of cleanliness and hygiene.

Just when she was still working hard to write, Xia Yu's afternoon class began, and many teachers knew that the scope of cleaning work that Yu Xin handed over to Xia Yu was not small, but he himself didn't seem to be in a hurry at all, and he was very leisurely and unhurried during class, and even delayed the end of class for several minutes.

Immediately afterwards, something happened that made all the teachers, including the principal, stunned, Xia Yu's class of more than 50 students took tools, and under the command of Xia Yu, in the distribution of class cadres, a vigorous cleaning campaign was carried out in full swing.

The curious teacher pulled a classmate to ask, it turned out that Xia Yu assigned an extracurricular homework with a comprehensive assessment of the subject, and this homework is not only difficult, but also very troublesome, but there is one point, if you can help him work, you can be exempted from this homework, and this assessment is given full marks.

The teachers admired but also had some doubts, you must know that the class in the third year of high school, the most difficult thing to do is Xia Yu's class, this method has not been used by previous teachers, but they are still not birds, weishenme others can't use it, Xia Yu has a strange effect? This left them puzzled.

In fact, there is nothing strange about this, Xia Yu's class wants to talk about thorns, in fact, there are only those ones, and they are particularly fierce, when something happens, the other students don't care anyway, so they make a fuss, but in case, if this gang of fierce guys encounters a more ferocious teacher, their arrogance is suppressed, and the camp is divided, it will be like a thousand miles of embankment, just because the anthill will collapse.

If everyone doesn't follow, no one will get the benefits anyway, and everyone doesn't care, but if someone follows, others will naturally feel that others can get the opportunity to get extra points for free homework, but I don't, isn't that a loss? These people, who didn't have much principle, naturally followed together, and the rest of them were even more frightened and tended to follow, and the result was obvious.

It's very simple, but it's not easy to do.

Of course, these students do not respect their colleagues as much as Xia Yu, and they love their elders, so they are reluctant to be forced to come, so when cleaning the teacher's office, the natural movements are inevitably a little louder, and the voice is inevitably a little noisy. ”

Then there was no opposition.

With so many helpers, there is no need for a class at all, all the work is done, Xia Yu checked it, felt very satisfied, and waved his hand, "Don't wait for the bell to ring after class, I will amnesty you for leaving school early." ”

The complaints of the classmates just now all flew out of the clouds, cheered, and the birds and beasts scattered.

Of course, Xia Yu himself was no exception, he didn't take anything empty-handed, he left the office with a swagger, passing by the offices of the three groups, and saw that Yu Xin was still buried in the test paper, Xia Yu politely went in and asked: "Director Yu, haven't you finished it yet, I'm free now, or, I'll help you a little?" ”

Yu Xin squeezed out a word from between her teeth: "Get out!" ”

Xia Yu was not angry, waved his hand with a smile, and left the office.

At this time in the school, some students who are not juniors of high school have already come out to move freely, leaving the area of the teaching building, everywhere seems to be so steaming, as if the buns have just been baked, and when they are about to arrive at the school gate, Xia Yu's eyes are inexplicably attracted by a middle-aged man with an inconspicuous appearance.

This person is wearing a special maintenance uniform, the corners of his eyes are wrinkled, his skin is slightly dark, his hair is flat, and he is no different from any other maintenance worker, after talking to the doorman, he slowly walked into the campus, after the bronze statue of Xia Yu holding his confession last time, everything looks so harmonious and natural. ,

But Xia Yu felt an extremely dangerous aura from his body, that feeling came from the bottom of his heart, and he couldn't control it at all, as if he was an instinctive sense, this feeling he had twice before even if he didn't get the ability, once when he was in Beifu, he encountered a bank robbery, and in the body of the robber, he warned in advance at that time, which caused the two robbers to finally fail and be brought to justice, and once it was a hike in college, and he stepped into a very strange place that no one had ever visited, there was a tall man with a mask, who also felt it in him.

At that time, he knew that no matter how the opponent changed his makeup, it was useless, as long as he had killing intent, he would definitely be sensed by himself at a certain distance, and the intensity of this perception represented whether the person was aimed at himself, and the strong was aimed at himself, and if it was not strong, it was likely to be aimed at other people.

This maintenance worker is not aimed at himself.

Xia Yu was originally a nosy person, not to mention that now this dangerous person was still in his own school, and what was endangering the safety of his students was endangered, so he naturally couldn't ignore it, so he quickly followed.

If there is no problem with that maintenance worker, I will cut out the heart for you. Xia Yu thought in his heart, the maintenance worker seemed to be going to work, but he went around outside the electrician's room, and immediately walked in the direction of the teaching building.

When he arrived at the teaching building, the man chose the most remote staircase to climb up, and along the way, although he also met many teachers, no one was alert because of his disguise, and even the person longed for Harada Keizhao who was going down to ask a few words.

When Xia Yu went up, he also deliberately greeted the teacher he knew loudly, to show that he didn't follow him on purpose, but really wanted to go here, but the person never stopped, climbed up and climbed, until he reached the top of the building, although the high school teaching building is very large, but it is mainly long, but it is not high, so there is no elevator, the height of the seventh floor is only, and it is not necessarily tiring to climb up and down.

Xia Yu saw him go up from the corridor, in order not to attract his attention, he immediately ran up from another nearest crossing, and when he peeked out at the entrance of the roof passage, he first noticed the middle-aged man who was dressed in maintenance clothes and harmless to people and animals, he was walking towards the girl who was standing on the side of the railing and quietly looking out, Xia Yu immediately recognized her just by looking at the side of this girl, she turned out to be the daughter of Harada Qizhao, the Harada Miri who almost died last time.

Seeing that the maintenance worker took out a handkerchief from his bag, obviously placing the coma potion, Xia Yu made up his mind, without waiting for him to show the murder weapon, he simply knocked it down, and was about to rush out, when a shout came from behind him.
