The three of them were stunned, Dong Que pushed the geometry again, and found that it was a little loose, Zheng Xiaofeng said: "It seems that we can push it." ”

Cheng Ruxue squatted down at this time, pointed to the ground and said, "Look." "When the two men looked closely, they saw that there were many imperceptible and unseen recesses on the ground, one after another, small linear depressions, like railroad tracks, which could allow the geometry to move back and forth in their direction.

Cheng Ruxue's eyes lit up, and she hurriedly looked at other geometric objects, and sure enough, there were the same buttons below, she immediately understood, and said, "I thought of it!" We can push the geometry to the side of the gap, and we can climb it up by stepping on it! ”

Dong Que immediately clapped his hands and said, "Wonderful! ”

Zheng Xiaofeng originally wanted to say that this was the case, but after thinking about it, he felt that something was wrong, so he asked: "But after pushing it over, the weight over there will increase again, and the ground will definitely sink more seriously." ”

Cheng Ruxue said: "It's okay, we can push some heavier geometry to the opposite side, so that this side can be warped, and it will be easier for us to climb up, it's very simple." ”

Zheng Xiaofeng nodded, there was no more problem in his heart, so the problem in this room was quite easy to solve. Just do it, Dong Que had to say "come and take a hand", and the three of them came to the same side, and with a strong force, they pushed the geometry step by step under the wall on the opposite side of the gap.

The geometry was indeed very heavy, but it was not to the point where it was laborious for three people to push, and as the ground gradually sank, it was easier to push, but just when the three of them thought that the situation would be all right, the opposite wall suddenly "boomed" and automatically descended, until the entire wall completely disappeared, and a pitch black appeared behind.

Zheng Xiaofeng subconsciously felt that something was wrong when he saw it, and said in his heart that it must not be so simple, so he hurriedly said: "Wait a minute, I'll go over and take a look." ”

The remaining two people still had some difficulty trying to hold on to the geometry, so Dong Que had to hurriedly run to the front and use his body to support it.

As he spoke, Zheng Xiaofeng walked to the darkness, raised the fire fold, and looked down, and saw that there was no bottom below, and he immediately understood, and said, "No! I can't push it anymore, if it's too heavy here, I'm afraid this geometry will fall directly! ”

Dong Que didn't understand, so he said: "If you fall, you will fall, isn't it more worry-free to have one less?" ”

Cheng Ruxue thought for a moment, shook her head, and said, "No, he wasted so much effort to design such a mechanism, and the solution must not be as simple as we thought before." ”

Zheng Xiaofeng nodded in agreement, if according to Cheng Ruxue's mode of thinking, if you want to know the real solution of this organ, I am afraid you must first figure out the real intention behind the current occurrence of these phenomena.

"Obviously, this West Transansde doesn't want us to move the geometry at will." Zheng Xiaofeng tried to analyze with Cheng Ruxue's thinking, "If we push some geometry down, maybe it will cause the entire ground to be completely unbalanced? ”

Cheng Ruxue's train of thought was one step ahead, and then said, "So...... While we push this geometry to this side, we also have to have another weight to match it, at least not too much difference in the geometry to push it to the other side? ”

Thinking that this guy was a geometrician, Zheng Xiaofeng clapped his hands and said, "Does he want us to find the volume of these geometric bodies, wait for them to be replaced with weight, and then push all the same weight to the sides?" ”

Cheng Ruxue suddenly frowned, if this is the case, it will be too troublesome.

Dong Que couldn't help scratching his head when he heard this, and asked, "Does it mean that you have to make it like a scale?" Can...... Why don't I think it's necessary to bother? Let's just push all the geometry to the middle, and the ground will naturally balance, won't it? When the time comes, we'll just push two of them to the sides with about the same weight, as long as we can balance our weight. ”

Zheng Xiaofeng and Cheng Ruxue listened, they were stunned at first, Dong Que thought he had said something ridiculous, but then the two of them couldn't help but light up, Zheng Xiaofeng said: "You are too talented." ”

Dong Quede is actually right this time, he simplified the problem all of a sudden, he doesn't have so many complicated thinking, and sometimes he can achieve the effect of breaking out of the confinement of thinking.

"Alright, let's try again." Zheng Xiaofeng said, the three of them pushed the geometry back again, and stopped when they reached the middle, although the position of this middle could not be found accurately, but according to the position of several gaps, it could still be roughly determined. The three of them continued to move, pressed the other buttons, pushed the other geometry over, and lined up along the centerline, the process was a bit troublesome, due to the influence of the ground tilt, the geometry that had been loosened was always difficult to maintain in its original position, and as the loosening became more and more, it became more and more difficult to maintain, and the three of them had to work separately, some were responsible for pushing, and some were responsible for controlling the position and balance, but fortunately, after some effort, this was not something that could not be done at all.

During this period, they also had a fluke mentality, can they not spend so much trouble, in some cases happened to maintain the balance, and at the same time there is a geometry that can be used to tiptoe under the wall of the gap, but unfortunately, this balance point has not been found, once they try to do so, it is always the side close to the gap that sinks badly, maybe these geometries are designed with their respective weights very elegant, making it almost impossible to hit the big luck, There may be some other mechanism under the ground that they don't know about, and if they don't solve the problem according to the designer's intentions, they won't be able to do it anyway.

So the three of them could only try step by step, but just as they were about to finish, they found another serious problem.

There are too many geometries in this room, and after they are lined up along the midline, there are almost a dozen left on both sides, that is, it is not possible to guarantee that all the geometries can be in the middle of the balance according to what Dong Quede said.

Cheng Ruxue wiped the sweat from her forehead, gasped, and said, "I understand, it seems that he just didn't want us to use such a simple method to deliberately design the number of geometries so much." ”

Dong Que saw it, and suddenly couldn't help but sigh sadly, and couldn't help scolding his mother again: "Oh-dare to love us just now, we all wasted our efforts for half a day?" ”

Zheng Xiaofeng also said: "It seems that we still want less." ”

The three of them were silent for a while, and they couldn't help but have a discouraged thought in their hearts.

Morale was cold for a while, but after a while, Cheng Ruxue said again: "Maybe we didn't waste our efforts in vain. ”

Zheng Xiaofeng and Dong Que subconsciously scratched their heads and asked, "Why?" ”

Cheng Ruxue opened her mouth while holding her forehead, obviously looking tired with her brain, and said: "Although we can't push them to the middle, we can also try to place them close to the middle line, I don't read much, and I can't say it theoretically, but it should be a very simple lever principle, and it is also common sense in life, that is, the gravity exerted close to the fulcrum has the least impact on the entire ground balance, and it may not delay us." ”

Dong Que thought about it, nodded seemingly clearly, and said, "Then it seems that we are thinking too much about it?" ”

Zheng Xiaofeng didn't seem very optimistic, and said: "You can give it a try, but I don't think the probability of being reliable is very high, and it can be seen from the process that we just tried to run from one side to the other, and the whole floor is very sensitive to weight." But anyway, we have to give it a try first, so we can find the next problem. ”

So the three of them could only continue to try with a bottomless mood, this time everyone didn't have that feeling of taking it for granted, and sure enough, before five minutes, Dong Que shouted not far away: "Damn, there is no button under this!" ”

“What？” Zheng Xiaofeng was stupid, adjusted the balance, and hurriedly went over with Cheng Ruxue to see, it was a cylinder, and after going around, I found that sure enough, as Dong Lack said, there is really no button under this geometry.

"That means it can't move." Zheng Xiaofeng said, Cheng Ruxue realized something, and said, "Let's see if there are any other things that can't be moved." ”

The three of them immediately scattered around to check, and soon each found out that there was really more than one geometry without buttons, and the same four cylinders, all distributed on the side away from the gap, and not symmetrical to each other.

Cheng Ruxue almost didn't think about it, and immediately asserted: "It seems that we have to find geometries that weigh about the same as them, and balance their positions first!" ”

Zheng Xiaofeng and Dong Que were so shocked when they heard this, they dared to study for so long, or did they have to find the volume of these geometries? If they're all made of the same material, then the weight must be the same, and the fuck is that this has to be calculated, the balance of the ground is already difficult to control, and the trouble of trying it randomly may not be as convenient as the calculation.

"I threw up." Dong Que said, "I never thought that in this life, I would actually learn junior high school mathematics knowledge in a tomb." ”

Zheng Xiaofeng raised his eyebrows and said, "Study? Are you sure it's not a review? ”

"We're not like you, we've had a good education since childhood." Dong Que replied, "The only sentence I know in mathematics is 'odd and even, symbols look at quadrants', and I don't know what quadrants are." ”

"Then you really ......" Zheng Xiaofeng thought about it and didn't continue, considering that Cheng Ruxue should not have had the opportunity to go to school, at most, there may be teachers in the orphanage, but what must be taught is not systematic. It seems that among the three people, the only one who is likely to calculate the volume of these geometric bodies is Zheng Xiaofeng, but it has been a long time since he learned that knowledge, and after he was in his early tens, all he was exposed to was some business things, and I am afraid that he really had to think about the volume formula or something.

The real trouble is that they don't have a ruler, so they can't get any accurate data about the geometry.
