The dim light staggered out an area of the underground hall, several moths flapped their wings, constantly hitting the glass cover of the lamp source, and the crowd of people in doll costumes gathered in front of the three stalls, leaning over from time to time to pick up a math textbook, and talking quickly and in a low voice.

Zhou Zhen wore the doll costume of the little yellow duck, squeezed through the crowd, squatted down in front of a stall, grabbed a sophomore math textbook in front of everyone, straightened up, and quickly flipped through it.

Seeing that the "frog" was immediately coming towards him, Zhou Zhen was ready to shoot at any time!

The other party and him are both "first echelons", and the "digital domain" is even more unsuitable for fighting than him, even if the two directly face each other, he is confident that he will not be defeated!

However, for the sake of prudence, he still has to wait for the other party's full attention to be attracted by the math textbook in his hand at the moment!

Just as he was thinking, the "frog" had already walked in front of him, and between the two sides, there was only a stall full of math textbooks.

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

However, just when he thought that the "frog" would snatch the math textbook in his hand for the first time like he had just treated the "big white goose", the "frog" suddenly took an abnormal step back.

"Everyone!"

"This transaction, there is a rule to be added!"

Add rules?!

Zhou Zhen frowned, on the way just now, Xie Qiongning told him that the organizers of this trade fair will often modify the trading rules inexplicably......

Now in this situation, is the other party just going to change the rules?

Or did you find something?

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

"Everyone knows that this teaching material is very dangerous!"

"If you are not careful, you may be infected by the mathematical knowledge in the textbook and become a 'digital infector'!"

"Therefore, in order to prevent anyone from flipping through the teaching materials at the trade fair, starting from this transaction, all future transactions will add a rule......"

"Turn off the lights and trade!"

As soon as the words fell, the "frog" immediately pressed the remote control switch in his pocket, and all the lights in the audience were extinguished in an instant!

This long-abandoned underground hall was immediately plunged into pure darkness, and it was impossible to see five fingers.

At this time, Zhou Zhen kept looking down at the textbook, and when he heard the word "turn off the lights", his heart suddenly tightened, but before he could raise his head, it was instantly dark in front of him!

Without hesitation, he hurriedly took two steps forward, stepped over the stall, and reached out to grab the position where the "frog" had just stood.

In the darkness, his arm was unhindered, and all his strength was lost.

Zhou Zhen stretched out his hand and grabbed a handful of air, the "frog" was no longer in place!

Whew......

The faint and rapid sound of footsteps faded away.

Zhou Zhen reacted immediately, and the "frog" escaped!

This newly added rule is aimed at him!

The other party has already discovered him!

Even though he didn't really get his hands dirty from start to finish!

With his mind racing, Zhou Zhen did not delay and quickly chased in the direction where the footsteps were far away.

Now there is no light source in the entire underground hall, the darkness is like a tide, the view is blocked, and his [Overclocking Interference] can't lock on to the other party, so he must follow immediately.

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

At the same time, although many buyers have become accustomed to the practice of "frogs" often changing the rules, in this strange illusion, they suddenly fell into darkness, and the whole crowd suddenly burst into a commotion.

"That's not good, right? Although turning off the lights to trade to avoid someone breaking the rules and reading the textbook during the transaction, we can't see anything, how do we know what we choose? ”

"Your rules are getting more and more unreasonable!"

"We really can't see the textbook now, but we can't even see the people, how can we trade?"

"Hey...... Turn on the lights! Just this one in front of me, I want it, turn on the light, and I'll pay for it right away! ”

"Yes, turn on the lights! If you are really not at ease, you can think of other rules, this rule is not reasonable at all! ”

"Hehe, the black light is blinding...... Someone just takes the textbook and runs away, you don't necessarily know if you pay or not......"

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

Everyone subconsciously looked towards the light source, and saw a figure wearing a cheetah doll costume standing outside the crowd, holding a strong flashlight in the shape of a pen, illuminating the darkness around him.

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

Hearing this, everyone looked in the direction pointed by the "cheetah", only to see that the three stalls were still in place, not moving, but the open space behind the stalls was empty, and there was no "frog" at all.

The "frog" who just said that he wanted to add rules here has long since disappeared!

All the buyers were stunned for a moment, and after reacting, one of the buyers, who was wearing a "cheese cat" doll costume, immediately asked: "The 'frog' just said that the lights were turned off and traded, just to escape?" ”

"Everybody's an old business, okay, why would he do this?"

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 faces of all the buyers hidden in the doll costumes changed, and a buyer wearing a "golden monkey" doll costume immediately said: "Do you know any mathematics, check the textbook!" ”

Before the others could speak, the "big white goose" immediately replied: "I'm a math teacher!" I can tell the difference between the real and the fake! ”

As he spoke, he immediately picked up a textbook and flipped through it.

The surroundings were dimly lit, and they could barely make out the outlines of each other's doll suits. The buyer next to him quickly took out his mobile phone and turned on the flashlight to illuminate the "big white goose".

※※※

Underground corridors.

There was no light, it was dark, and even through the doll costume, the musty smell peculiar to the long-sealed space was constantly coming from the tip of the nose.

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

He had just chased into this corridor, and suddenly tripped over something, and the moment he was about to fall, he immediately did a somersault, and his body landed steadily.

Immediately afterwards, Zhou Zhen reached out and touched the ground, and a soft touch came from his fingertips, and in the softness, there seemed to be a layer of relatively hard frame...... It is a hood in the shape of a "frog"!

This should have been thrown away by the "frog" when it ran away in order to reduce the weight!

Zhou Zhen frowned, listening to the footsteps that were 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 physical strength and speed of the "frog" were obviously very average, and the distance between the two quickly narrowed under his full sprint.

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

"Ahhhhh!!hh

Suddenly, there was a scream of extreme pain in front of me!
