"So what? How did this cover hang in mid-air? ”

Li Gengai touched the wall, as if he was feeling something, and smiled slightly, "You say, what is the most inconspicuous color in the light?" ”

"It must be black."

"No, it's transparent."

Planarians climbed on top of the wall skin, turned a corner along the wall skin, and led directly to the back of the wall, and everyone crossed the wall, but saw that those planarians suddenly made a big turn, and they were actually able to crawl out of thin air.

The people sitting on the wall felt that it was magical, but those planarians did not fight or grab, and seemed to line up very naturally, crawling in the air to the other side, and heard the sound of "banging" water, there was a sound like dumplings, in the dark, it was the range of flashlight, and it seemed that there was a water source ahead.

Everyone looked at each other, the corners of Li Reform's mouth hooked, one leaned over, and jumped directly from a height of ten thousand feet, this move shocked those people above almost didn't pick out their eyeballs, but Li Reform jumped down two or three meters, and fell lightly in the air, like walking on the ground, began to slowly and leisurely turn in a circle, and then whispered, "Sure enough." ”

"You can come down now."

Silence –

Silence –

Or silence -

The second one of the Thorn Iron King came down without warning, and when he stepped on the ground, Gujing Wubo's face also flashed a light "Huh"?

Seeing this, King Suo also came down the third, and the second dog and the big dog saw that everyone was safe and sound, so they jumped down.

When he landed and found that he was stepping on this mid-air, it was really like stepping on the ground, and even the sound of kicking was the same, and he suddenly whispered in disbelief.

"How is that possible?"

"How could such a thing be?"

"It's a transparent stone!"

The One-Thorn Iron King squatted down, rubbed the ground with the Emei Thorn, looked at the traces that were rubbed, and whispered, "There is nothing impossible, it's just that any light source illuminates the stone, which can't reveal the shape, and it's clever but not clever." ”

Looking back at the courtyard of the underworld, at this angle, it blends with the darkness and looks gloomy, and the previous vanished trestle bridge winds for a distance to reappear.

It turned out that it was only in this mountain, and the clouds were deep and did not know where.

"No, I still don't know how this chamber is suspended in the air."

To be saved is to be saved, and the road ahead is clear, and this doubt, which is still unresolved, is still hovering in the hearts of everyone.

Li Gengai asked the same question again, "In the dark, what kind of color is the most inconspicuous?" ”

"It's transparent."

"No, it's darkness."

The power shone into the dome, but saw countless chains hanging down, and among these chains, there were four huge chains, pulling the four corners of the courtyard, as if dragging the entire courtyard out of thin air.

"It's impossible, the weight of a house is unimaginable, even if it is supported by chains."

"So, this is the overall setting of tension and pulling, which is ingenious, with the help of this unique mountain topography, but you can't see it."

Tensile monolithic structure, here refers to the condensation of "tension" and "whole".

The universe operates according to the principle of tensile consistency, that is, gravity is a balanced tension network, and the planets are isolated points in this net. According to this idea, the tensile monolithic structure can be defined as a self-supporting and self-stressed spatial grid structure composed of a group of discontinuous compression members and a set of continuous tensile elements.

The stiffness of this structure is provided by the equilibrium prestress between the tensile and compressive elements, which has little stiffness until the prestress is applied, and the magnitude of the initial prestress, plays a decisive role in the shape of the structure and the stiffness of the structure. Due to the inherent natural characteristics of the tensile monolithic structure, the properties of the material and cross-section are maximized, and the super-large span building can be constructed with as little steel as possible.

The mechanical analysis of the tensile monolithic structure, similar to the grid structure of the prestressed hinged joint, contains internal mechanisms except for some special graphics, showing geometric flexibility. For research purposes, in addition to the general form-finding and static-dynamic analysis processes, an intermediate process is sometimes used: the study of stability, mechanism, and prestress states.

The analytical model of the tensile monolithic system must take into account the nonlinear characteristics and the existence of the equilibrium self-supporting process.

The nonlinear analysis of the static properties of the tensile monolithic structure can be made into a model of dynamic relaxation based on the relaxation principle or the matrix catch-up method of Newton's Rafsonian process.

"It's not magic, it's not special effects, it's a seemingly gravity-defying structure, it's called a tensile whole. With a rigid pole and a soft rope or chain, the self-tensioning structure is formed, in which the traction and compression force form a stable whole, rigid and flexible, inseparable, but due to the visual effect of anti-common sense, it is impossible to form. ”

Softness and rigidity can stabilize and not panic.

This long transparent road in the air, I don't know where it leads, everyone follows the planarian, the speed of the planarian wriggling, naturally can't catch up with the footsteps of people, about two or three minutes, the sound of "bang" water seems to be in the ears.

"Wow-"

"Wow-"

With the sound of gurgling into the water, the fog suddenly rose in front of him, and the fog that slowly shrouded him began to spread like dry ice, and everyone quickened their pace, but a little light began to flash in front of them, so that they could see the direction clearly without a flashlight, but what they saw was shocking to their eyes.

Stone phosphorus, wave clean, weird and really evil. But I saw that the peak in front of me stood upright through the sky, and the winding stream was deep and deep through the earth. Two cliffs and flowers and trees compete for strangeness, and several pine fences are green. The stone cliff is abrupt, and the moss is lubricated and grows with green moss; The peaks and rocks overlap, the ravines and bays are ringed, and a misty hot spring appears in the pretty flute.

The back garden digs a well and makes a silver bed, and the gold bottle is a cold slurry.

The square pond is like the bright eyelashes embedded in this place on the Tianshan Mountain, the soup is very broad, and the white bubbles that rise in the pool water "goo-goo-goo- See the long flow of Linzhang water, and look at the glory of the garden fruit.

Everyone chased the planarian here, but the planarian fell under the dumplings at his feet, and disappeared after throwing himself into the hot spring.

And the pond surface is far away floating large and small water lily leaves, the big one is like a basin, the small one is like a worm money, the rhizome is thick, erect or creeping, the floating water leaves float on the surface of the water, showing round, oval or ovate, the apex is obtuse and round, or it seems to have been split by someone with an axe from the middle, split into a horseshoe shape or heart shape.

The water lily platform is surrounded by water, surrounded by crystal clear hot spring water, duckweed, green and clear.

The one-thorn iron king picked up a water lily leaf with the tip of the Emei thorn, but saw that the rhizome of the lotus leaf was short and thick, some of them were like hearts, the size was about a palm, the top was shiny, and the bottom was red with sharp hairs, which was no different from the normal water lily in the outside world.

This is the variety of small lotus leaves, and there is a distance from the shore, there is actually a diameter of more than 3 meters of smooth leaf surface, leaf edge roll, like a lotus leaf floating on the water surface of the emerald green jade plate, its leaf veins and the general lotus leaf vein structure is different, into a rib shape, like an umbrella frame, floating on the water surface, very spectacular.

Looking at the lotus leaves from a distance, it looks like a freshly completed ink painting. The lotus leaves are dotted, such as an open green umbrella, or floating on the surface of the lake, or standing between the blue waves. The breeze comes, the shape is thousands, it looks delicate and elegant, and it is indescribable.

Everyone looked stunned, thinking that what they should face when they came here was a greater danger, but they never thought that it would be such a fairyland on earth, and they were a little hesitant for a while.

"That lotus leaf is really a big lump."

The second dog refers to the oversized lotus leaves that resemble a radial reticulation.

"That's Wang Lian."

"Wang Lian??"

"The royal lotus is the largest leaf in the world's aquatic plants, so it has a lot of buoyancy and can withstand objects weighing up to sixty or seventy kilograms without sinking."

"Sixty or seventy kilograms?"

The eldest dog and the second dog gasped and sighed.

Strange –

Li reform's eyebrows were deeply wrinkled into a word "Sichuan", he had never heard of plants still alive on the hot spring pool, and more importantly, the planarians that followed should like to survive in the clear water, and they didn't climb so far and came to die all the way, don't you know that after being scalded, no matter how much they heal, they can't live?

What's more, if it is a lotus leaf, then how can there not be a lotus here, there are a lot of lotus leaves, how unique is this hot spring pool, it will be full of lotus leaves, but not even a lotus flower?

Wang Lian is famous for its delicate and changeable flower colors and strong fragrance. The flowers of the royal lotus are very large, all the thorns on the outside, the number of petals is also very large, and the ovary is densely covered with thick thorns, which stretch out of the water and open every evening, which is very fragrant. The first day is white with the aroma of white orchids, the next day it gradually closes, and in the evening it opens again with the petals turning pale red to deep red, and on the third day it closes and sinks into the water, which is not spectacular.

However, there are already Wang Lian's leaves here, but there is not a single flower, which is incredible.

Li Reform stood still, before the matter was clarified, he would never act rashly, but the big dog and the second dog could not bear it, and the second dog was excited, and heard that Wang Lian would not sink even if it was loaded with a weight of sixty or seventy kilograms, so he hurriedly took a vertical step, jumped on a piece of Wang Lian, and stood on Wang Lian's leaf petals to swagger, and was happy.

"Hey- really, look, look-"

But seeing that the two dogs were carried away, they were overjoyed, and their eyebrows were dancing, and King Suo was frightened, "Come down, now the situation here is not clear, you kid come down for me!" ”

Ergou pursed his mouth a little unhappily, "Come down, come down-"

But at this moment, there was some movement in the water, and at this moment, a toad as big as a naughty child, "plopped", jumped out from the depths of the water, stretched out its tongue, rolled up the second dog like a roasted sausage, stuffed it into the abdomen, turned around and "plopped" again, and fell into the pool.
