The incandescent lights illuminated the familiar classroom, the lectern was empty, the blackboard was mostly clean, and only a few corners were left with some chalk marks that had not been erased.

The students gathered in twos and threes, and there was no math teacher around, and the atmosphere was relatively relaxed, as if it was time for class to end.

Bang bang bang......

A muffled sound came, and as soon as Zhou Zhen looked up, he saw Ren Rui standing not far away with a fierce expression.

Zhou Zhen frowned, and was about to go up to help, Daniel Zhang Hao saw him wake up, seemed to have finally come to his senses, suddenly broke Ren Rui's hand, and quickly ran towards the back door of the classroom.

Ren Rui chased after him and gave Daniel Zhang two more feet.

Daniel Zhang Hao was kicked and crawled, and finally escaped.

I don't know what the reason is, Ren Rui stopped when he chased to the door, and did not continue to chase out, but returned to his original position and sat down.

Seeing that Daniel Zhang had escaped from the classroom, Zhou Zhen thought about it, there was nothing to do, he casually opened the homework book in front of him, ready to write the homework first.

There are still ten questions in the book.,Same as before.,Nine of them are still empty.,The answer is clean.。 Only under the first question, there are dense steps and answers.

Zhou Zhen glanced at the first question and found that he had written a total of three solutions, and the steps and processes of each solution were very different!

The first solution is all numbers and symbols; The second solution is a large number of incomprehensible points and lines; The third solution is complex geometry......

His eyes swept over this question, Zhou Zhen then looked at the second question, the number of this question was constantly changing, he wanted to solve the problem, but no matter how hard he tried, he couldn't see this question clearly......

※※※

Room 2809, Building 51, Yaxin Court.

Second bedroom.

The curtains were drawn firmly, and the chest of the person lying on his back rose and fell rhythmically, making the sound of even breathing, and the whole room was very quiet.

Zhou Zhen had just fallen asleep, suddenly opened his eyes and sat up from the bed.

He sat down at the computer desk next to him, turned it on, entered an online shopping platform, and soon bought a pair of myopic glasses on it.

Immediately afterwards, Zhou Zhen didn't turn on the lights, and went out directly and walked into the living room.

When he got to the living room, he sat down on the couch and turned on the TV in front of him......

"Boom...... ......"

"......"

The TV that was repaired by Zhou Zhen before,At this moment, it is all black and white horizontal and vertical lines,At the same time,There is also a harsh electric sound in the speaker。

However, Zhou Zhen didn't seem to notice anything unusual at all, he sat quietly on the sofa and watched TV with relish......

※※※

Jingle bells!

At 06:00, the alarm clock rang, and a crisp bell broke the silence of the second bedroom.

In the gap between the closed curtains, a white light of the morning light lit up faintly.

Before the second ringing began, Zhou Zhen had already reached out from the quilt, pressed the alarm clock, and then got up neatly.

He opened the wardrobe, turned out a clean suit to change into, and when he put it on, he saw the computer next to him that was standby, and he couldn't help but feel a little strange, the last time he used the computer, he didn't turn it off?

Thinking of this, he immediately walked over, turned off the computer, and then simply cleaned up and went out immediately.

I was late for the first day of work yesterday, so I had to go to the office early today......

※※※

Twenty minutes later, Zhou Zhen walked into the office in high spirits.

Jin Qingfeng, who was on duty last night, yawned and sat in front of the computer flipping through a document, seven or eight cigarette butts were stuffed in the ashtray at hand, and the exhaust fan and air purifier hummed slightly, and the smell of smoke in the room quickly faded.

"Team leader, morning!"

Zhou Zhen looked around, Chen Mao and Shi Xiaoli's seats were empty, and it didn't seem to have arrived yet, he nodded to Jin Qingfeng and said hello.

Jin Qingfeng extinguished the only small piece of cigarette in the ashtray, wiped his face with one hand, seemed to force himself to cheer up, and said in a hoarse voice: "Xiao Zhou, come so early today?" ”

Zhou Zhen walked to his seat and sat down, and said, "I woke up a little earlier in the morning, and I was fine anyway, so I came over first." Team leader, what time are you on duty and still not resting? ”

Jin Qingfeng said vaguely: "It's almost ...... Wait for them to ......."

As he spoke, he rubbed his eyes and began to pack his things.

At 7 o'clock, Chen Mao and Shi Xiaoli entered the door one after another, and after everyone said hello to each other, Jin Qingfeng explained the work progress and situation to the three people, mainly Chen Mao and Shi Xiaoli, and left work with the key......

※※※

Time passes slowly, going to work, getting off work, going home...... Three days passed quickly.

The three days have been very calm, and there have been no cases in the entire Sheriff's Office, especially since there have been no new "digital virus" cases.

I have watched a considerable part of the monitoring replay, but I have never found any trace of Huang Xurong and Luo Yuchen, and even Zhou Zhen himself has not appeared in the monitoring screen.

On the way home, Zhou Zhen frowned, if he continued like this, it would take him quite a while to check all the surveillance. And if the date of contact between the three of them, it is not June 1...... Then he'll have to check all the videos from May again!

"Tell Team Lu tomorrow, it's best to go to Huang Xurong and Luo Yuchen's house to investigate......"

Making up his mind, Zhou Zhen began to recall his dreams in the past few days while driving the car......

Daniel Zhang in the dream is now getting better and better with him. Almost every time I get out of class, I borrow my notes...... Give it to him.

But except for the first time, the more he went to the back, the less "digital energy" he received, and even when he got up this morning, he couldn't feel the increase in his strength.

In addition, Ren Rui is very hostile to Daniel Zhang, and will beat Daniel Zhang whenever he has the opportunity.

Every time he was beaten, Daniel Zhang Hao would escape from the classroom......

The other classmates didn't change much, and none of them were willing to lend him notes or homework......

"Tonight, we have to think differently......"

"I asked all my classmates to borrow homework, but no one would lend it to me, so I should only choose one goal......"

"Also, Brother Hao lent me the notes because I helped him......"

"So, after I have chosen a target, I first have to investigate their preferences......"

"As long as there is a place where you can help, there should be a chance to ......"

Thinking of this, Zhou Zhen kicked the accelerator and sped up the speed of going home.
