When I finally walked out, I breathed a sigh of relief, and my gaze was unnaturally fixed on the wooden door. The wooden door looks quaint and has a sense of history. I tried to push it open, but found that as soon as my hand touched it, before I could use any force, the door opened on its own.

In front of you is an enclosed stone chamber. In front of the entire stone chamber, there are statues with their backs to the three of us, and their faces cannot be seen. The fat man and I swept around, and when we found that there was no trace, we couldn't help but change directions, that is, consciously go around to the front of the statue.

That's three statues of celebrities. As for why I say that, it's because I know the names of the three statues in front of me, two of which have signs underneath. One is Aristotle, the other is Plato, and it is not an exaggeration to say that these two learned men of the old century are enshrined here, and next to these two statues, the other statue is much younger. Not only does the man look so young, but his clothes are also the kind of Western European Middle Ages, and unlike them holding books, this man holds a long sword, looking proudly ahead, and his eyes are full of the domineering spirit of a king, and the wisdom of a smart person. Looking at the sign placed under him, it was strange that there was no name written on it, and I felt a little strange that the person who enshrined him here respected him so much, why didn't he even write his name.

The fat man standing next to me suddenly jumped in front of me, half-squatted down, leaning in front of Aristotle, and his gaze stopped at his feet, "Xiao Ke, look."

Looking in the direction pointed by the fat man, I saw that in front of the three statues, each placed a fruit the size of a thumb, red, blue, and black. The fruit that was set before Aristotle was blue. The curious fat man, before I could stop him, stretched out his hand straight towards the blue fruit.

Other!

What's wrong?

After hearing my words, the fat man replied puzzled, and then changed his understanding, the whole person was stunned at first, and then sneered and stuffed the blue fruit into his arms, and said timidly: "Xiao Ke, I didn't expect such a thing to happen, I think the person who designed this church wants us to have more experience, since people have made a move, we have to take it, right!" ”。

If you have done something wrong, you can still be so righteous and awe-inspiring. My head suddenly hurts for no other reason. Things went back to just now, just as I opened the mouth, the fat man had just taken the blue fruit with his hand, and to my surprise, the environment around us also changed suddenly.

A small stone room, on a long table on either side of us, was filled with lit candles. Before we could react, in front of us, a line of words suddenly flashed out: choose the longest candle to come out!

It was so simple that both me and the fat man couldn't help but feel that someone was teasing us. "Sample, fat man, I'm not an imbecile!" As he spoke, the fat man walked straight ahead, his eyes wandering away from the candles on the long tables on either side, and I followed behind, and whenever I was about to pick up the longest candle, I always thought that there was a longer one in front of me. Gradually, the fat man and I came to an end.

Things took a turn at this time. When the empty fat man and I were about to walk back, we were surprised to find that there seemed to be a wall behind us, and it was impossible to move an inch at all. At this point, I can be considered to understand the design of the human mind, in the journey of life, we always think that the invisible things "ahead" are the best, but often forget the side, do not grasp the present, so that in the end empty-handed.

The fat man, who suddenly came to his senses, looked at the back in a daze, the shining candles, and shouted loudly: "Who is that, give us another chance!" If you can, I will go out, fat man, and my daughter-in-law will not marry first, and then study for a few more years, and do more good deeds along the way."

Things that have to be believed, weird things happen again. In the dark, I seemed to hear the sincere voice of the fat man, and felt that the ground under our feet was constantly moving, and it was dark in front of us, and the surrounding wind was full of whirring, and after everything subsided, the surrounding environment changed suddenly.

At this moment, the fat man and I were standing on a high platform, and the ground around us was covered with vertical stabs, which were unusually dazzling. On the side next to us, there are three balls: large, medium, and small. Among the many stabs on the ground, there was a slightly raised mat, and looking through the small gap, you could see that under the mat, there was a red stone twist. Obviously, the designers wanted us to use the ball to smash it on the mat, and once the force applied was strong enough, the mechanism would naturally be activated.

Under my surprised gaze, a thin rope that had been tied to my arm fell inexplicably. An amazing scene suddenly happened!

I saw that during the falling period of the string, the string seemed to be magnetized by something, so that it was constantly changing, because the string was constantly absorbing the fine crumbs that came out of nowhere. Eventually, when the rope fell to the ground, it suddenly grew in size and weight.

The fat man, who was about to throw the ball downward, immediately withdrew his hand and looked at me in confusion, "Xiao Ke, what happened just now?" Now, which one should I throw? ”。

I took the biggest ball in the fat man's hand, put it back on the ground, looked at the dim top, slowly sorted out the thoughts in my head, and reasoned: there are two very difficult problems in front of us.

First: Due to environmental factors, we don't know how high the top above our heads is.

Second, in the process of falling, the ball will absorb fine debris that comes out of nowhere, so that when it finally falls, the volume and weight of the ball itself will change.

It can be said that among the three balls of small, medium, and large, each ball has the potential to become the one that opens the mechanism. Let's assume that the mass of the ball is 1kg, the medium ball is 3kg, and the large ball is 5kg. Because in the process of falling, the ball will unnaturally absorb fine chips, and increase its own weight. In other words, △g = σ (t) + σ (m).

The increased weight is affected by two factors, one is the time t of fall, and the other is the mass of the body. It can be said that in the case of a certain mass, as the falling time is getting longer and longer, the weight of itself is increasing more and more. But now we have a tricky problem: because the sky above us is dark, we can't see the top. Because it takes a long time for the ball to fall, at present, in the absence of other facilities, it can only be thrown straight upwards to make the ball fall for the longest time. And because of the existence of two factors, it cannot be said that the weight of the big ball on the ground is the largest. The reason is simple: there are four possibilities for the final weight of the three balls falling. 1 Small = 10kg, Medium = 9kg, Large = 8kg2 Small = 9kg, Medium = 8kg, Large = 10kg 3 Small = 8kg, Medium 10kg, Large = 9kg 4 Small = Medium = Large.

After saying a long paragraph, the fat man rolled his eyes at me, "Xiao Ke, according to what you say, let's throw something up first to estimate the top!" ”。

No way! I immediately denied the fat man's idea, and when I saw the fat man looking over unwillingly, I hurriedly explained: "It's very simple, you can't grasp that degree at all." Even if you hit the sky above and the surrounding area is too empty, the sound is clear, but relatively speaking, the result is not so ideal for a heavy ball. Once the thrust of the ball is exerted, there will be a bounce between the ball and the top wall, and the time will be smaller."

"Well, I'll throw the balls together on the mat on top of the mechanism," the fat man replied.

I shook my head again, "The distance between the high platform and the ground is a certain height, and when letting the ball go down, you must roughly determine the trajectory of the ball, otherwise the ball will float to the side, and it will only be in vain."

The deflated fat man suddenly became irritable, "This doesn't work, that doesn't work, Xiao Ke, what do you say!" I can see it, not only the ancients in China like to fix those strange things, but even foreigners are tormented by our descendants."

The words are not coarse. I really feel like what the hell is going to do? Are we going to be trapped here? I asked myself like this, and the jade pendant hanging around my neck suddenly lit up. The fat man with a dead face suddenly stood up from the ground and said in surprise: "Mopei seems to be going to help us."

We still can't figure out the situation, only to see a light shot out of the jade pendant, straight down on the ball, and then the ball slowly floated in my hand, I just took the ball, the hand seems to be caught by something, uncontrollably put the ball in the hand, to the front side wall to throw.

Because the distance is too far, you can only see approximately. A small parabolic ball streaked through the air, and we thought it would hit the wall and fall straight down. Who knew that the ball actually went directly into the wall, and then I heard a loud "bang", and the ball that entered the wall seemed to have received a strong elastic force, soaring into the sky, and when it reached the highest point, it fell straight towards the mat on the mechanism.

Bang!

With the sound of an explosion, the stabbing on the ground suddenly disappeared, and the high platform slowly shrank, and on the side next to us, a junction suddenly appeared, and the candles we had seen earlier were suddenly placed in it. I walked down the platform and looked at the wall where the ball had hit earlier, and was surprised to see that there was a hole in the wall the size of a small ball, that is, the ball entered the hole, because at the bottom of the hole there might be a spring-like or seesaw device that could bounce the ball back into the air.

"Xiao Ke, go, I swore a poisonous oath just now" The fat man waved at me with a regretful expression, I nodded lightly and hurriedly followed. (To be continued.) )
