Concubine Yun rubbed her eyes, turned her head back and forth, and looked again, but she still couldn't see where the numbers were, and wondered, "Strange, why can't I see anything?"

After asking, she asked Lin Jiao and Yu Kerou beside her, "Can you two see the numbers?"

Lin Jiao and Yu Kerou shook their heads at the same time.

Concubine Yun looked at the others again and found that the others were also confused.

At this time, Wu Gan spoke: "Only people with sufficient intensity of stereoscopic vision can see the numbers hidden in the black and white grid. The strength of stereo vision is largely determined by innate visual genes. Of course, some people who are born with weak stereoscopic vision can also improve the intensity of stereoscopic vision to a certain extent through special training. ”

Hearing Wu Gan's explanation, Jiang Yuanzheng, who was walking in front, did not stop his steps, and said with a smile: "Hehe, that's right, it is true that only people with stereoscopic vision of sufficient intensity can see the hidden numbers." 3 and 5, hehe, we're going to catch house 9. ”

"Catch?"

Bai Yongqi asked curiously, "What do you mean?"

Jiang Yuanzheng replied without looking back: "You'll know later." ”

The crowd continued along the smooth, snow-white road.

The speed at which they walk, imperceptibly, increases.

About another five or six minutes passed before they passed between the two black-and-white lattice rooms on the left and right.

Concubine Yun couldn't wait to ask, "What is the number on these two houses, is there a 9?"

Long Mingxiang shook his head and replied, "There is no 9." 7 on the left and 2 on the right. ”

"Oh, okay. ”

Concubine Yun said indifferently, "7 and 9 are not far apart." ”

No one answered, everyone remained silent very tacitly and continued to hurry.

About another four minutes passed.

The crowd stood again in the middle of two black and white lattice rooms.

Concubine Yun was the first to ask, "How much is it this time?"

"Huh?"

Long Mingxiang was surprised, "No." Not only is there not a 9, but there is also a number 5 that has appeared once before. The other number is 4. ”

"Repeated?

Concubine Yun was puzzled, "Can it be repeated? How many times can the same number be repeated? It won't be repeated a hundred or eighty times! If that's the case, when will we come across the number 9? There is no pattern to follow at all!"

"Nope. ”

Bai Yongqi suddenly spoke, "It's not just numbers that are repeated. ”

"What do you mean?" Concubine Yun looked at Bai Yongqi and asked.

Bai Yongqi replied: "This house is still the same house we have met once before. ”

"Liar, huh?"

Concubine Yun couldn't believe it, "The black and white lattices on the house are exactly the same, how do you know it's still the same house before?"

"Nope. ”

Bai Yongqi glanced at Wu Gan with a determined look, and said categorically, "The captain gave me a set of exercises for cultivating eyesight before. I'm just getting started, but I'm sure it's the same house we've seen once before. ”

"Oh my God, can the house still grow on its own legs?" Concubine Yun still didn't believe it.

At this time, Wu Qian opened his mouth and explained: "The house here is indeed like having long legs, and you can run by yourself." Not only can these houses run, but also the road under our feet. I did the math that since we set foot on this road, we had walked briskly for about fifteen minutes, and the distance we had traveled was about three thousand meters. ”

Speaking of this, Wu Gan paused, turned his head, looked at the road behind him, and spoke again: "But in fact, in the whole process, the absolute distance we moved was less than 1,500 meters. ”

"Uh..."

Concubine Yun's expression was exaggerated, "A house that can run, and a road that can run, what the hell is this place." ”

"Hahaha..."

Jiang Yuanzheng, who had been observing Wu Gan and the others in silence, suddenly smiled, "That's why I said, if you want to find Room 9, you must not just keep moving forward and try your luck." You've got to find a way to get it. ”

"How?"

Concubine Yun asked rhetorically, "We don't even know how it runs, how can we catch it?"

Jiang Yuanzheng heard Concubine Yun's question, and an unfathomable smile appeared on his face.

Obviously, he must have known how to find room 9 as quickly as possible.

Not only Jiang Yuanzheng, but the other three deputy marshals should also know it.

It's just that they didn't intend to say it immediately, as if they deliberately wanted to use this to frustrate the sharpness of Wu Qian and the others.

Wu Qian saw through the thoughts of Jiang Yuanzheng and the others at a glance.

He smiled contemptuously and said, "Carving insect skills, what's so difficult." ”

When the sound fell, he immediately opened the yin and yang pupils and looked at the six paths.

In his yin and yang pupils' field of vision, all the fog would disappear in an instant.

After just a dozen seconds, Wu Qian stared at Jiang Yuanzheng, smiled faintly, and said confidently: "To put it bluntly, this is just a large machine. The middle road resembles a conveyor belt. There are a total of nine decks on both sides of the conveyor belt. Each booth fits seamlessly into a black and white lattice room. There is also space and several tracks under the road. When we walk on the conveyor belt, the conveyor belt is also moving at a constant speed in the opposite direction to us. At the same time, the nine black-and-white cubicles are constantly changing positions back and forth according to the fixed program and the induction device. I think that in normal mode, the probability of them appearing on every deck should be the same. But because of the intervention of human factors, the No. 9 room we want to find will deliberately play a game of hide and seek with us. As long as this artificial setting is not lifted, even if we continue to walk like this until we reach the end of the road, even if we go back and forth countless times, I am afraid it will be difficult to come across the No. 9 room we are looking for. ”

Wu Qian said while admiring the wonderful expressions of Jiang Yuanzheng and the others.

Having said so much in one breath, Wu Gan deliberately paused at this, and then smiled contemptuously: "However, the intelligence of this large machine is still too low. There is a very obvious loophole in its fixing procedure, that is, the nine bays distributed on both sides of the conveyor belt are fixed and cannot move freely like the nine black and white lattice rooms, and at the same time, the nine black and white lattice rooms must occupy all nine booths at the same time, and none of them can be missed. Grasping this, as long as the number of companions exceeds nine, then, no matter how much the person in charge of this large machine tries to operate in the dark, it will not be possible to make any of the nine black and white lattice rooms go unfound. ”

"Hahaha..."

Concubine Yun understood Wu Gan's explanation, and immediately smiled, "Captain, in fact, there is no need for nine people at all. These houses are lined up on both sides of the road, and one person standing in a fixed position can hold two booths at the same time. There are only nine booths in total, isn't it enough to have five people in the same company? ”

"That's right. ”

Wu Gan nodded and said, "It's true that you don't need nine people, five people are enough." However, since there are many of us, let's divide into several groups. ”

Saying this, Wu Gan's gaze swept over everyone one by one, and then continued: "Ming Xiang, Concubine Yun, Lin Jiao, Kerou, the four of you turn back and go to the first and second booth positions to guard." ”

When Long Mingxiang, Concubine Yun, Lin Jiao and Yu Kerou heard this, they nodded at the same time, and said in unison: "Okay, captain." ”

Wu Qian said again: "Fengwen, Yongqi, the two of you also turned back and guarded the third and fourth booth positions. ”

"Yes, Captain. Wang Fengwen and Bai Yongqi nodded at the same time.

Wu Qian looked at Yao Qingping and Lian Bingyue again, and said, "Qingping, Bingyue, in addition..."

Speaking of this, Wu Gan paused, and after a little hesitation, his eyes fell on Bi Jingjing's face.

Before he could speak again, Bi Jingjing pursed her lips and smiled, and took the initiative to speak: "Don't worry, captain, I will stay here with the two of them." ”

"Hmm. ”

Wu Gan nodded when he heard this, then looked at the rest of the people and said, "The rest of the people will continue to walk forward with me." ”

Lin Zhanfeng, Huang Xiao, Zheng Bingjie, Li Meng and Li Xueman said in unison: "Yes, captain!"

Immediately, everyone divided into several routes and prepared to act separately according to Wu Gan's arrangement.

Jiang Yuanzheng looked at the scene in front of him, and smiled helplessly: "Okay, don't leave yet." ”

Everyone stopped, turned their heads one after another, and looked at Jiang Yuanzheng.

Wu Gan looked directly at Jiang Yuanzheng and asked, "What's the matter, Marshal Jiang? Are you ready to lift the special settings?"

When Marshal Jiang heard this, he shook his head with a smile and said, "Forget it, I really convinced you little guy." Your IQ and analytical skills are much better than your father's. I remember that when I first brought your father here more than three years ago, your father was dizzy for a whole day and couldn't find room 9. Hahaha..."

Wu Gan listened to the laughter coming out of Jiang Yuanzheng's mouth, and he didn't feel funny at all, but felt that it was a great insult to his father.

Of course, the reason why Wu Qian feels this way is mainly because of the subjective feelings mixed in it.

If he didn't suspect that his father's disappearance was directly related to Jiang Yuanzheng, perhaps, he wouldn't have found Jiang Yuanzheng's joking tone and laughter particularly harsh.

This is probably what people often say, "The speaker has no intention, but the listener has a heart".

"Marshal Chiang. ”

Wu Gan interrupted Jiang Yuanzheng's laughter expressionlessly, and said in a calm tone, "I think, let's hurry up and finish our business and then chat." ”

When Jiang Yuanzheng heard this, he stopped laughing.

He didn't say anything more, and he didn't get angry because of Wu Gan's attitude towards him, but directly put his right hand into his trouser pocket and took out a black remote control that was no bigger than his palm.

There are several buttons on the remote control, each marked with nine red Arabic numerals from "1" to "9".
