In fact, the three of them have already gone to the next level, and the reason why they are so pure is that they didn't react. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Since they came up counting the steps, although they didn't say it when they went downstairs, the three of them still subconsciously counted the steps, there was no reason, it was just inertial thinking.

It was precisely because none of the three of them paid attention to it, and it was purely a subconscious action alone, that it was not until they had already gone downstairs that everyone realized that there seemed to be a lot of stairs just now.

"It can't be such a coincidence, can it?" Wang Shang said again and again and turned around and climbed back along the stairs, obviously not believing his subconscious.

In fact, not only Wang Shang, Zhao Zhiao and Sun Siwen also followed, it is rare to really encounter the legendary event, even if it is their own illusion, they always have to verify it, right.

But to everyone's disappointment, when they looked back at it, the steps were back to 12 verses.

"This ...... What's going on? Did I count wrong? Sun Siwen obviously couldn't accept this answer.

"It's impossible, it's just that one person is wrong, how can all three of us be wrong? This staircase must have been 13 knots before. Zhao Zhiao said affirmatively.

"Let's recall, is there any difference between going downstairs and going upstairs?" Wang Shang squatted down next to the steps and said while studying.

"Different...... What's the difference, it's just that the number of steps is different. ”

Admittedly, if the three of them were to deliberately feel the difference, or to say hello to any of them in advance, the three smart people would definitely feel the difference between the two stairs, after all, if there is an extra staircase for no reason, it is impossible to raise the entire floor by one section, so the steps of the staircase must have changed.

But in this sudden situation, no one cared about the steps under their feet, and the funny thing was that the minds of the three of them were all focused on what to eat at noon.

So it's understandable that no one noticed the difference between going up and down the stairs.

Wang Shang didn't expect anyone to know, he just asked casually, just in case, and the biggest possibility was to put it on his own research.

Because everyone was at the very top of the staircase, on the small platform that led to the rooftop, it was impossible for the staircase to change much, otherwise they would definitely notice it.

And the extra step is impossible to be symmetrical if it is in the center, and if it is at the top, the three will definitely find it.

To sum up, the extra section is the most likely at the bottom of this floor.

Sun Siwen and the others obviously thought of this, and the three of them all squatted down to observe.

This careful observation really revealed some clues.

There are a total of 12 sections of stairs on the entire floor, although they are quite average when visually inspected, but there is a layer that will be subconsciously ignored when visually inspected.

That's right, it's the section where the stairs begin.

Since it is the first floor that starts to climb upwards from the flat ground (the aisle of the floor), this level has no strict relationship with the steps above, it can be equal or not, and most of them only look at the height of the steps at a glance, and ignore this first section.

Now because of careful observation, Wang Shang really saw the difference.

The first step of this floor is indeed a little higher than the steps above.

The part that is not very tall, probably less than 10 centimeters.

If it is vertically higher than 10 centimeters, some people may still notice it, but the first floor of this staircase actually has a certain inclination, which narrows the naked eye error to a few centimeters.

At this point, if it weren't for deliberate observation, there would be basically no possibility of discovering it, not to mention that even if it did, no one would suspect it.

Is it rare for the first section of the staircase to be uneven with other steps? It's not uncommon.

However, Wang Shang and the others had just experienced the thirteenth step of one of the seven incredibles, and it was completely impossible to doubt it.

"In other words, is there an extra step here just now? And it didn't come until after we went upstairs, so we went up to 12 verses and came down 13 verses? Sun Siwen asked suspiciously after discovering the cattiness of this section of steps.

"That's right, think about it carefully, it seems that when I went downstairs, I did feel that the last two sections were getting shallower, but at that time we were still talking about what to eat, and the gap was too small so I didn't care, and now I realized it in retrospect."

Zhao Zhiao expressed his opinion, although it was a bit of hindsight, but what he said did make sense.

"Found it, the hidden staircase is here." While the two were talking, Wang Shang also found his target.

On the wall that touches the staircase, at the bottom of the staircase, there is something like a mechanism in one direction.

Apparently this is the extra staircase of that section, and now he is retracted into the wall, so it is restored to 12 sections.

This mechanism is very cleverly designed, the gaps around it are very small, and the whole pattern is integrated with the surroundings, so it is really difficult to spot if you don't look closely.

"This is the truth about the extra staircase? How do I think it's so easy for us to hack? Sun Siwen was surprised.

"No, it's not a crack, the principle is known, but what the hell is this mechanism for, it's impossible for someone to be so boring to make a mechanism to scare people." Wang Shang hesitated for a moment, but still asked.

"Well...... Indeed, this thing was clearly made when the building was built, just like that window...... Wait, same as that window? Zhao Zhiao seemed to have thought of something.

Having said this, Wang Shang also understood.

If this thing was made when the building was built, would the person who built the blocked window not know? Obviously impossible, right?

Assuming that this was designed by two people, and the two didn't know each other, then Wang Shang could only sigh that these two people were so big ha, and the organs were all built together, but they hadn't discovered each other yet.

But if they were built at the same time, how could there be no connection between the two things?

"If there is a connection between the two, it is too far away." Sun Siwen also understood the meaning of Zhao Zhiao's pause, "After all, this is the seventh floor, and the window is on the third floor, you said that the two were made by the same person, but if there is a connection, it is not very likely." ”

"No...... I think it's quite likely, think about what we were aiming for in the first place. Zhao Zhiao said.

"Yes...... I also think it's very likely...... And, the three incredible ones we wanted to crack in the first place...... It is likely to be a joint system ......"

Wang Shang also took the opportunity to answer, and as he spoke, he paced to the other side of the wall where the mechanism was installed.

There, there is an elevator room.

And it is the elevator room where the 13th person is overweight in the seven incredibles...... (To be continued.) )
