The people who once lived on this land are awe-inspiring, and they have left behind a precious wealth of wisdom, and the 80 sculptures that stand here today are thought-provoking.

Jiang Erye glanced at everyone and concluded: "The 80 statues represent the summary of the architectural technology and philosophical ideas of a period, and the secret of the entrance to the ancient city is in the sculpture." The message conveyed to us is a reflection on the evolution of life, and aside from other values, we only study the value of the mechanism as a mechanism to open the entrance to the ancient city, the orientation of the sculpture, the bias angle, and what kind of mechanism needs to be used in such a huge design layout. ”

Han Qingxin had specially studied the ancient mechanism skills before preparing for this trip, and now he realized that even if he learned more, it was just a superficial surface, "It is unheard of to use eighty sculptures as the opening and closing of the entrance to the ancient city gate, what kind of mechanism should it be." And after thousands of years, who can guarantee that these mechanisms are still working. Power is required to open any kind of mechanism, and I would like to know what kind of power can sustain it for thousands of years. ”

Most of the mechanisms need to be driven by gears and other mechanical parts, and metal and even stone parts can hardly withstand the erosion of thousands of years. I am afraid that the metal size will rust, and the use of stone in mechanism is also more extensive, although there is no need to worry about rust, but it wears out faster than metal parts. Han Qingxin's doubts are also worth considering, yes, thousands of years or thousands of years have passed, what kind of kinetic energy drives the mechanism here, what is the endless energy, solve these problems, the meaning of the existence of sculpture and the way to enter the ancient city may be solved.

Zhu Beichen sighed with awe and sighed: "Yes, thousands of years of time, they may have existed for longer than we believe, if the machine has decayed and cannot be used, wouldn't it be that the gate of the ancient city will never be opened?" ”

This possibility is not impossible, but since the great man entered the city with ancient books more than a thousand years ago, it proves that at least at that time, the machine was still intact.

The fat man rested for a while, jumped up violently and said, "No, let's climb up and take a look, we may find something." ”

Each statue is about 100 meters high, and the building statue is made of a very smooth surface building material, which looks like stone on the outside, but the hardness is significantly stronger than the hard granite, and there is no trace of carving in any part of the statue, and it looks like it is made without carving. Even if he wanted to climb up, he couldn't focus on it, Han Qingxin shook his head and said: "I can't go up, what materials do they use, it looks like a piece of smooth and flawless jade." ”

Is it jade? Han Qingxin's words triggered Zhu Beichen's reverie, if it is impossible to say that it is jade, where can there be such a huge jade for carving into a human appearance, not to mention that the texture is completely different to the touch, looking closely at the statue itself is actually opaque, and then squinting and changing several angles to observe, I always feel that there is a steady stream of light sources being sucked into the statue itself. Touching the palpable surface of the statue, if it is really absorbing sunlight, the surface of the body does not feel the slightest heat. The endless energy of the ages, the calm and calm between the squares, and the slight breeze blowing, Zhu Beichen denied the role of the wind. Moreover, according to last night's electronic equipment detection, the area of the ancient city is absolutely amazing, the scale of the building is unimaginable, even if it is the entrance of the ancient city, the energy required to open it must be extremely large, and the wind energy cannot meet the requirements.

Raising his head slightly to look at the soft light above his head, Zhu Beichen observed the situation around him with the help of the sun, and blurted out: "Could it be a light source, using solar energy to drive all the statues, and aggregating energy to finally open the gate to the entrance of the ancient city?" ”

Hearing this, everyone was inexplicable for a while, and they all fell into thinking, the feasibility of this energy source exists. To their surprise, were the ancients able to use solar energy at that time?

Qijian said: "Didn't you take Su Hao's diary?" Judging from the content, he should have entered the ancient city, and the only person who entered the ancient city after the Han Dynasty back then, will he leave clues in his diary? ”

If you don't remind you, you really forgot Su Hao's diary, Zhu Beichen took off his backpack and took out the diary, and quickly scanned the general content of each page, looking for a description of 80 statues. Fingers stopped in front of a page of paper, indeed Su Hao's diary recorded this paragraph, simply leaving a few meaningless Chinese characters: suspended ancient city, human camera bracket.

Zhu Beichen said angrily: "This guy is so tight, he is not even willing to write in detail in the diary he wrote, so he left a few words, which is useless." ”

Unwillingly, he continued to check the contents of the diary on the pages before and after, none of which were related to the statues, it can be said that the diary recorded that Su Hao had come to this square, and he also saw all the statues, but he did not leave the key to solve the mystery.

Su Hao, when he heard this person's name, Jiang Erye suddenly thought of a big man in the Republic of China. Sadly, the man died young, and was never seen again after an expedition to a secret location by many of the best players on the Tangled Path. Jiang Erye said: "The Su Hao you are talking about is the one during the Republic of China?" ”

I didn't expect Jiang Erye to know this person, it seems that Su Hao's fame should have been so big half a century ago, and such a character finally threw his life here. After getting their nods and acknowledging, Jiang Er Ye recalled: "It is said that Su Hao is a bit selfish in his personality, and he records the places he has visited but does not leave the steps to unlock the mechanism, which is in line with his style of doing things, and he doesn't want anyone to set foot on this land like him." ”

In fact, speaking of which, Su Hao already knew that this line was dangerous and abnormal for the last time he fought backwards, otherwise he would not have been entangled with so many people since he had always liked to work alone, and even contacted the Jiang family at that time, but for various reasons, the Jiang family did not participate.

July silently analyzed Zhu Beichen's words and said: "It makes sense to think that it is driven by light energy, the larger the arrangement used to drive the mechanism, the more energy is needed, and a full 80 sculptures are used to drive, and no other energy source can do it." "At least at that time, there was no such thing as nuclear energy, so solar energy was the most realistic use, and the building materials of each statue were the same, and they all had a common interest in light, they were slowly absorbing the light source, and the naked eye could not detect this phenomenon, but July was particularly sensitive to subtle changes in the surrounding environment.

Since most people agree with Zhu Beichen's point of view, Jiang Erye said that it is necessary to summarize all the statue data and input it into the computer, analyze the characteristics of the statue from the perspective of location distribution and monomer, and make reasonable use of light sources, which must be comprehensively used in the different position distribution of each statue to absorb the light and store it.

They spent the whole day walking around the square, scanning the three-dimensional silhouette of the statue with a detector in hand. The Jiang family brought a wide variety of technical equipment with different effects, and everyone else was surprised that the power of a family was so huge. Finally, not long after the sunset, a series of surveying and mapping scans were completed, and the data was summarized on the supercomputer in Jiang Erye's hand.

After some tossing, everyone was a little exhausted, but fortunately they still had a bunch of compressed food to replenish their strength. After a simple meal, Jiang Erye couldn't wait to turn on the computer to process the data of the day. A complete topographical map was formed on the screen, with a total of eighty statues distributed in the form of red dots on the screen. As Shichima said, the distance between the two adjacent statues is roughly the same, but the distribution of all the statues is not regular, as if they follow some kind of pattern on the whole map.

Let's talk about the lighting factor, because the previous analysis of their layout may have been designed to fully accept the daylight. It turns out that the distribution of each statue is based on the surrounding mountains, and any statue can receive the sun's rays at the moment when the first rays of sunlight shine in the morning. In this way, Zhu Beichen's original idea was established, and the energy of the driving mechanism was indeed the light source.

"Countless **** nights, have they been absorbing sunlight for thousands of years? It seems that the material of the statue is very similar to our current solar panels. The fat man said.

"Have you ever wondered why this ancient city is hovering above our heads, and do you still think that they absorb light every day just to open the entrance to the ancient city?" The distribution of 80 statues covers every corner of the square, and on the computer screen it is like 80 pillars in the sky, carrying the invisible ancient city hovering above everyone's heads? The mystery in Shichima's heart was suddenly explained.

The statue symbolizes the evolution of human life, and the different facial expressions depict the perception of different periods of life, and also serves as the place where the secret of the ancient city is buried in the sand, and controls the key to open the gate of the ancient city. It can be said that every statue here is a treasure in the history of human civilization that combines architectural mechanics, art and high-end technology, but it is a pity that they can only stay here forever to carry this ancient city.

Jiang Erye said: "Well, if you look at their location distribution carefully, mechanically speaking, it is reasonable to disperse the pressure of the ancient city, and convert solar energy into some unknown ability to hold the entire sand-buried ancient city high above our heads." If these statues were destroyed, the ancient city might have collapsed. ”

After listening to Jiang Erye's words, Zhu Beichen approached the fat man and said, "You have to be careful, we have no place to drill this city, and it will definitely be smashed into a meatloaf." ”

The fat man scoffed at Zhu Beichen's words, knowing that this kid was making fun of himself again: "Fat man, I want to become the foundation of the ancient city, and your kid is no better." ”
