I'm not sick! So do my other personalities!

Zhou Zhen frowned. The second drop of "digital rain" found Sister Nan?

But how is this possible?

Just now in the "digital forest" of the "Huangjia Club", he also played the role of a mathematics teacher. From the beginning to the end, the first drop of "digital rain" was not noticed at all!

And now, Sister Nan has just started to act!

The most important thing is that this is not the school in the suburbs of Binhai City, but the "digital forest" of Bicheng Rose Garden!

Through the "equation" of the first drop of "digital rain", he pulled out a vacant classroom from the "digital forest" of the school in the suburbs of Binhai City.

The second drop of "digital rain" is neither in this vacant classroom nor has any connection with the "digital forest" in Building 156 of Bicheng Rose Garden. How did the other party find it? ?

At this time, Zhou Zhen saw the second drop of "digital rain" approaching. He didn't have time to think too much and immediately walked up to meet the opponent.

"Teacher!" Zhou Zhen stared at the second drop of "Digital Rain" dressed in bright red, shouted very respectfully, and at the same time blocked the opponent's face impartially.

He remembered very clearly that in the memory given to him by "Doctor Ash", "Doctor Ash" acted as "Digital Rain" in the spiritual world and wanted to obtain the power of "Digital Rain", but was discovered by "Digital Rain", and then There is something wrong with the body.

Now, Sister Nan is acting as the second drop of "digital rain" in the classroom behind her. Once she is hit by the real second drop of "digital rain" in front of her, it is very likely that the same situation will occur!

Therefore, he must now hold back the second drop of "digital rain"!

While thinking, Zhou Zhen grabbed the second "digital rain" by the wrist and asked directly: "Teacher, are we going to the amusement park now?"

When the second drop of "Digital Rain" heard this, her steps suddenly stopped. She did not agree immediately. Instead, she looked at the classroom not far away and replied hesitantly: "It seems that class is on..."

Seeing that the second drop of "digital rain" came to class and did not discover Tao Nange, Zhou Zhen breathed a sigh of relief and immediately said: "No!"

"I'm outside the classroom right now, so I'm definitely not in class."

"The teacher must have made a mistake!"

With that said, he pulled up the second drop of "Digital Rain" and was about to walk in the opposite direction to the classroom.

But as soon as he took a step forward, Zhou Zhen discovered that the seemingly slender "Digital Rain" was standing motionless, and he couldn't pull him away at all!

At this time, "Digital Rain" shook his head slightly, looked fixedly at the classroom, and said in a very firm tone: "I want to go to the classroom to take a look."

"I feel like I'm already attending class inside!"

this……

Zhou Zhen frowned suddenly, and when he saw "Digital Rain" continuing to move, tapping the terrazzo floor of the corridor with his stilettos, walking towards the classroom with a clear goal, his mind raced, and he hurriedly said: "Let's play the merry-go-round! "

"I am a Trojan horse..."

When he used this move in the past, the second drop of "digital rain" would be very cooperative.

But this time, the second drop of "Digital Rain" shook it without looking back, and simply said: "We will play after class. I have to go to class now!"

Zhou Zhen held "Digital Rain"'s arm tightly, but he couldn't hold him back at all.

He moved quickly with his feet and turned to the front of "Digital Rain". While using [Overfrequency Interference] to send a message to Tao Nange in the classroom, he stared into the eyes of "Digital Rain" and said quickly: "Teacher, After you agreed to my confession last time, our time together was too short!"

"Now, I just have time, why don't I take you to a place where no one is around, and we can get along well."

"Teachers and students live in harmony, which is more in line with the school's regulations."

"Teacher, what do you think?"

Listening to Zhou Zhen's theory of living in harmony, the second drop of "digital rain" finally stopped, but only paused for a second before continuing to walk towards the classroom: "I will be with you."

"But now, I have to go to class!"

"If I don't go to class now, another one will come and teach."

"If that person saw you outside the classroom, you would go crazy!"

another?

Zhou Zhen instantly understood the meaning of the second drop of "digital rain". The other party was talking about the first drop of "digital rain"!

Because what he just played was the first drop of "digital rain"!

Just as I was thinking about it, the second drop of "digital rain" had already walked to the classroom door and grabbed the handle of the front door...

※※※

In the classroom, bright skylight shines in from the spacious windows, and the class is grand.

Tao Nange stood in front of the blackboard, holding a piece of chalk. While giving a lecture, he quickly wrote a line of blackboard writing: "The general steps for using derivatives to find the monotonic interval of a function are..."

"...use the point where the derivative of the function is 0, and divide the definition interval of the function into several small open intervals in sequence..."

"If a function is continuous at a certain point, then the function..." [Note]

The crisp and sweet lecture sound echoed in the classroom. Feng Enbei and others were sparsely sitting on the seats, looking confused and staring at the blackboard.

There were seventeen people attending the class in the classroom. Judging from their clothing, age, and appearance, they were all members of the "Digital Forest" in the 156 villas in Bicheng Rose Garden.

Their appearance has changed to a certain extent from when they were in the "Digital Forest" of the villa, but their general characteristics are still exactly the same and can be distinguished completely.

Tao Nange was not surprised by this. Zhou Zhen had already told her the reason before starting class...

This classroom is also a “digital forest”.

And in this "digital forest", there is a rule that can change all living beings pulled in, whether they are ordinary people, compatible people, or infected people, into the appearance of students!

While thinking, Tao Nange continued to read the content in the mathematics book, but as she read, she suddenly had a very strange feeling.

It seems that I have established some kind of connection with some special existence...

Driven by instinct, Tao Nange glanced at the back of one of her hands. In her field of vision, there was a vague stroke on the back of this hand that was very unfamiliar in theory, but she always felt that it was extremely familiar. hurt.

There was no blood flowing out of the wound, only countless tiny figures, like visible microorganisms, scrambling to squirm.

In an instant, several forgotten memories appeared in Tao Nange's mind.

She remembered that she was trapped in the Starry Sky Ferris Wheel by rising floods at the Fudi Amusement Park in Tongfu City;

She remembered that when she was lining up for the Starry Sky Ferris Wheel event, she and Zhou Zhen played a game of riding a wooden horse. First, Zhou Zhen acted as a wooden horse and picked her up; then Zhou Zhen asked her to be a wooden horse and picked her up. Also changed clothes on her shoulders;

She remembered again that in the wilderness at night, in an abandoned industrial area, she locked eyes with Karl Ax, the eleventh sage of the "Twelve Sages" who was following her, and pulled the trigger, starting a fierce and violent battle. dangerous battles;

She still remembered that she was standing on a high platform, taking the military green T-shirt from Zhou Zhen, and happily entered a green rotating slide under the arrangement of the staff...

These memories are extremely real, whether it is the scene, the mood at the time, or the recall of details, everything is as if they were there.

Tao Nange was immersed in it for a while, but soon she realized that this was what Zhou Zhen said. Her "equation" was synchronized with the "equation" of "Digital Rain"!

Some of the memories she just saw should be hers, but some should not be hers!

Tao Nange quickly calmed down and looked at the back of his hand again.

What you see is smooth white skin, and the back of your hand is normal skin, healthy pink and white. Under the skylight, the light green blood vessels are clearly visible.

It was as if the digital wound just now had never existed.

Tao Nange quickly adjusted herself and was about to continue her lecture when a piece of information was suddenly forced into her mind...

It's Zhou Zhen's [Overfrequency Interference]!

Tao Nange's expression changed slightly, and without any hesitation, he immediately walked off the stage, randomly picked an empty seat among the students, and sat down directly.

Immediately afterwards, she put the math book she was just talking about on the empty desk to serve as her own textbook. She quickly took off the cheap Santa hat and threw it into the drawer. At the same time, she took off her feet. Her bright red stilettos were stuffed into the belly of the table, and she sat barefoot on the seat...

Tao Nange had just finished making these preparations when the front door of the classroom was pushed open.

A familiar figure dressed in red walked in straightforwardly.

The silhouette of the visitor was exactly the same as Tao Nange's, and the outfit he wore was exactly what Tao Nange was wearing just now.

The only difference is that the other person's body is covered with dense numbers.

Tao Nange lowered his head slightly and did not look at the second drop of "digital rain". Instead, he stared at the math book on his desk, pretending that he was also a student in this classroom.

At this time, the second drop of "digital rain" had already reached the podium. She looked around the entire classroom condescendingly, and her eyes soon fell on Tao Nange.

However, perhaps because he had met this student in class before, the second "digital rain" gaze did not linger too long on Tao Nange. After a brief pause, he glanced directly over.

At the same time, a textbook appeared out of thin air on the hand of the second "digital rain", and an undulating, high and low sound wave resounded throughout the classroom.

The second drop of "digital rain" started teaching directly.

The moment "Digital Rain" started teaching, Tao Nange discovered that all the students, including her, had piles of math books, homework books, notebooks, and various stationery items on their desks...

Tao Nange had already experienced this kind of inexplicable class. Without hesitation, she immediately opened a notebook, picked up a pen, and started taking notes.

※※※

Outside the classroom, in the spacious and dark corridor, Zhou Zhen stood alone outside the front door.

Seeing the front door of the classroom closing again, he breathed a sigh of relief.

Sister Nan moved quickly, and the second drop of "digital rain" found nothing.

Thinking of this, Zhou Zhen immediately took out his mobile phone.

Under normal circumstances, in the "digital forest" of this school, he cannot use the "digital domain" or real objects.

However, after playing the role of the first drop of "digital rain", he obtained part of the "equation" of the first drop of "digital rain" and is no longer restricted by this aspect.

Zhou Zhen quickly set an alarm for one minute later.

The sound of the alarm clock is the bell for the end of get out of class here!

Tick ​​tock...tick tock...tick tock...

One minute passed quickly, and the alarm clock rang on time.

Jingle Bell……

At the moment when the alarm clock rang, Zhou Zhen heard the second drop of "digital rain" coming from the classroom through [hidden eavesdropping]: "get out of class is over."

Zhou Zhen immediately crossed off the alarm clock.

The next moment, the front door of the classroom opened, and the second drop of "digital rain" came out.

I just finished the class and the second drop of "Digital Rain" seemed to be in a very good mood. When I opened the door and saw Zhou Zhen, he immediately said: "Let's play the merry-go-round together! You be the merry-go-round!"

Zhou Zhen smiled and nodded: "Okay!"

As soon as the words fell, everything around him turned into overwhelming numbers.

These numbers disappeared quickly like a colony of ants returning to their nest, and returned to Zhou Zhen's body in the blink of an eye.

Without the cover of numbers, the classrooms and corridors that had been so real just now suddenly brightened up and returned to the splendid basement of Building 156 of Bicheng Rose Garden.

The second drop of "digital rain" disappeared.

The spacious and luxurious villa was empty, with only Zhou Zhen and Tao Nange standing in the high-ceiling living room.

Looking around, Zhou Zhen took a deep breath, looked at Tao Nange, and said without any nonsense: "Let's go!"

Tao Nange nodded immediately, and the two quickly climbed up the stairs and walked towards the door.

The various decorations along the way were dazzling, but they were not in the mood to appreciate them at all. Their footsteps moved quickly along the marble corridor.

When he was about to arrive at the exit, Zhou Zhen suddenly thought of something and immediately asked: "Sister Nan, where is the math book I gave you just now?"

Hearing this, Tao Nange looked at her hands. Her hands were empty now and she didn't take anything.

At this moment, she was still wearing the bright red dress, high heels and Santa hat, and they were all gone. There was no place to hide books anywhere on her body.

Tao Nange immediately replied: "The book is missing!"

"Probably stayed in that classroom!"

When Zhou Zhen heard this, his expression suddenly became solemn.

It would be okay if he really stayed in that classroom.

That math book originally belonged to that school!

But I am afraid that in the form of "numbers", that book has parasitized in Tao Nange's "equation", making Tao Nange a carrier!

Thinking of this, Zhou Zhen quickly asked: "Sister Nan, don't hide anything now. Tell me, is your current mental state different from just now?"

Tao Nange looked at Zhou Zhen, thought about it seriously, and quickly replied: "Yes!"

"I really want to ride you now!"
