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

Dim yellow lights alternately illuminated an area of ​​the underground hall. Several moths flapped their wings and constantly hit the glass cover of the light source. People in doll costumes gathered in front of three stalls, leaning over to pick up a book from time to time. Mathematics textbooks, talking quickly in a low voice.

Zhou Zhen, wearing a little yellow duck costume, squeezed through the crowd, squatted down in front of a stall, and in front of everyone, grabbed a high school mathematics textbook, straightened up, and quickly flipped through it.

Seeing the frog walking towards him immediately, Zhou Zhen was ready to take action at any time!

The opponent and he are both first steps, and the digital domain is even more unsuitable for fighting than him. Even if the two of them fight head-on, he is confident that he will not be defeated!

However, to be cautious, he still had to wait for the moment when all the other party's attention was attracted by the math textbook in his hand to take action!

Just as he was thinking about it, Frog had already walked up to him. The only thing between them was a stall filled with mathematics textbooks.

Zhou Zhen's whole body began to secretly accumulate strength.

However, just when he thought that the frog would snatch the math textbook from his hand just like he did to the big white goose just now, the frog suddenly took an abnormal step back.

Everyone!

This transaction needs to add a rule!

Add rules? !

Zhou Zhen frowned. On the way here, Xie Qiongning told him that the organizer of this trade fair would often change the trading rules inexplicably...

In this situation, the other party just wants to change the rules?

Or discovered something?

Thinking of this, Zhou Zhen couldn't figure out the other party's details for a while, so he didn't act rashly and continued to pretend to read the mathematics textbook in his hand.

Everyone knows that this teaching material is very dangerous!

“If you’re not careful, you may be infected by the mathematics knowledge in the textbooks and become a ‘number infected’!”

So, in order to prevent anyone from messing around with textbooks at the trade fair, starting from this transaction, all future transactions will have a rule added...

“Lights out deal!”

As soon as he finished speaking, Frog immediately pressed the remote control switch in his pocket, and all the lights in the place went out in an instant!

This long-abandoned underground hall immediately fell into pure darkness, and it was impossible to see even one's fingers.

At this time, Zhou Zhen had been looking down at the textbook. When he heard the word turn off the lights, his heart suddenly tightened, but before he could raise his head, his eyes suddenly turned dark!

Without any hesitation, he quickly took two steps forward, crossed the stall, and reached out to grab the frog where he had just been standing.

In the darkness, his arm was not hindered by anything, and all his strength was in vain.

Zhou Zhen reached out and grabbed a handful of air, and the frog was no longer where he was!

Thump thump thump…

The sound of subtle yet rapid footsteps gradually faded away.

Zhou Zhen reacted immediately and the frog escaped!

This newly added rule is aimed at him!

The other party has discovered him!

Although he never really took action from beginning to end!

With his mind racing, Zhou Zhen didn't waste any time and quickly chased in the direction where the footsteps were disappearing.

Now there is no light source in the entire underground hall. It is dark and the line of sight is blocked. His [Overfrequency Interference] cannot lock on the opponent, so he must follow him immediately.

Otherwise, when the other party runs away, it will be really troublesome!

At the same time, although many buyers were used to Frog's practice of frequently changing the rules, they suddenly fell into darkness in this strange fantasy world, and the entire crowd suddenly became commotion.

Isn't this not good? Turning off the lights in the transaction prevents people from breaking the rules and flipping through the textbooks during the transaction, but we can't see anything. How do we know what we have chosen?

Your rules are becoming more and more unreasonable!

It is true that we can't see the teaching materials now, but we can't even see the people. How can we trade?

Hey...turn on the light quickly! I want this book in front of me. Turn on the light and I'll pay for it right away!

Yes, turn on the lights quickly! If you are really worried, you can think of other rules. This rule is simply unreasonable!

Haha, it's a fool's errand...someone just took the textbook and ran away. You may not know whether he paid or not...

Just as the buyers were complaining, a beam of snow-white light lit up from the darkness.

Everyone subconsciously looked towards the light source, and saw a figure wearing a cheetah doll suit standing outside the crowd, holding a pen-shaped strong flashlight in his hand, illuminating the surrounding darkness.

Cheetah pointed to the back of the stall and said calmly: Don't make any noise, 'frog' is gone!

Hearing this, everyone looked in the direction pointed by Cheetah and saw that the three stalls were still in place, not moving at all, but the open space behind the stalls was empty and there was no sign of Frog at all.

The frog who was here just now talking about adding more rules has already disappeared!

All the buyers were stunned. After reacting, one of the buyers wearing a Cheese Cat doll costume immediately asked: 'Frog' just said that he would turn off the lights and trade, just to escape?

Everyone is already in business, so why would he do this?

Upon hearing this, a buyer wearing a Peacock doll costume suddenly said: Could it be that the teaching materials are fake?

As soon as this sentence came out, the expressions of all the buyers hidden in the doll costumes changed. A buyer wearing a golden monkey doll costume immediately said: Is there anyone who understands mathematics? Check the textbook!

Before anyone else could speak, Big White Goose immediately replied: I am a math teacher! I can tell whether the textbook is true or false!

As he said that, he immediately picked up a textbook and started flipping through it.

The light around them was dim, and they could only barely make out the outlines of each other's dolls. The buyer next to him quickly took out his mobile phone and turned on a flashlight to illuminate the big white goose.

※※※

Underground corridor.

There was no light, just darkness. Even through the doll clothes, the musty smell unique to sealed spaces that had been sealed for many years was constantly coming from the tip of my nose.

Zhou Zhen followed the location in his memory and quickly chased him out of the hall.

He had just chased into this corridor when he tripped over something. The moment he was about to fall, he immediately flipped and landed firmly on the ground.

Immediately afterwards, Zhou Zhen reached out and touched the ground. There was a soft touch on his fingertips. There seemed to be a harder frame hidden in the softness... It was a frog shaped headgear!

This should have been thrown away by Frog in order to reduce the load when he escaped!

Zhou Zhen frowned. Hearing the footsteps getting farther and farther away, he quickly identified the direction and immediately chased to the left.

He was completely unfamiliar with the terrain here, but the frog's physical strength and speed were obviously very average. Under his full sprint, the distance between the two quickly narrowed.

Zhou Zhen immediately took out the scalpel and was ready to fight at any time, but at this moment...

Ah ah ah ah ah!!!

Suddenly there was an extremely painful scream from ahead!
