The whole palace is simple and heavy, with a dark red tone, a golden tile kiss, carved railings and paintings, exquisite carvings of corridors and windows, flying towers, and verandahs resembling belts, connecting all the buildings and gathering together in the wide field in front of the main hall.

There are two other waterfalls hanging on the stone walls on both sides, falling directly into the high and deep canyon, the fog stirred up, constantly floating around the building, refracting the sunlight in front of the building, reflecting the seven-colored rainbow light, just like the heavenly palace jade que in the Taoist water and land painting, rippling with the blurred treasure light.

Under the illumination of the golden tiles on the top of the palace, it looks even more dazzling and charming, and it makes people feel like they have come to the Nine Heavens God Realm!

Sun Daqiao looked at the fairyland-like palace and said: "The Yiguan mound of Beifu is built on such a high mountain, it really seems to be suspended in the sky, but it is in line with Liu Yu's purpose, maybe they can really attract the souls of the dead into the sky, but, how can it be such a cultivation?" This main peak is not without flat ground. ”

After they walked up to the main peak from the mountain road, the place where they came up was a dirt slope similar to an alpine meadow, which could be leveled and built a mound here.

This is already the top of the mountain, and the construction of the mound here is already in line with Liu Yu's expectations, and it has to be hung on the mountain wall, which undoubtedly increases the difficulty of construction.

Song Siyuan picked up the binoculars, observed the mound on the cantilever, and explained to everyone: "You still remember the hanging temple I mentioned, I feel that whether it is the cantilever hall or the mound in front of me, it is for the sake of solidity that the stone is used to build a building on the mountain wall. ”

"We have also seen the decay of those villages in the cantilever basin, and if these buildings were built on flat ground, the erosion of the soil alone would destroy the buildings."

Speaking of this, her tone became serious: "Especially a giant complex like this, the buildings are too tall, ordinary loose soil can not carry them at all, these soils are close to waterfalls, and it is estimated that the water content is also very high, even if the foundation is tamped, in a time span of nearly two thousand years, the soil is destined to settle, once the settlement occurs, the foundation of the entire palace will be changed because of the bearing force, and it will not be able to support it, I am afraid that it will collapse directly, or even fall down the mountain, and break the bones." ”

"Knowing what the result would be, would the craftsmen of that time choose to build a palace on a gentle slope? This is a major event related to the Northern Expedition of the Yin Soldiers, and no one dares to slack off easily. ”

"Is it safe to build on a cliff? No, it is also subject to erosion and changes in the load-bearing capacity. ”

"Of course, they can use building technology and mechanics to transform the environment and minimize the impact of natural and gravitational factors on the building," Song explains. ”

"For example?"

Yue Guanchao puffed his teeth.

Song Siyuan saw the look of the vulgar martial artist, and became more serious, and continued to explain: "I guess that the Beifu Yiguan Mound and the Hanging Temple are the same half-inserted beam-type mechanical structure......"

The "L" shaped gap on the half-waist of the main peak is a specially created rock formation plane, and then a stone trough is built on a slightly inclined plane, which runs through the thick wooden beams to form a solid foundation to carry the main hall, and the concave mountain walls on both sides of the plane can also use the same mechanical structure to build a pagoda.

In this way, most of the gravity of the building is docked backwards, forming a backward pitching force, and the huge mountain bears most of the gravity of the building, so that the building is less dependent on the rock plane, and of course the foundation settlement is avoided.

At the same time, because the building is built in a gap in the mountain wall, through the blocking of mountains on three sides, most of the terroir can be avoided from directly eroding the building, making it difficult for the terroir to harm the building, and the waterfalls on both sides also play a role in dividing the water, and even the erosion of the water flow also turns into a waterfall and becomes a part of the landscape.

What's more, the state of the mountain hugging!

Tiantong Peak with an extremely strong texture, completely imprisoning most of the frame of the building, in the case of the mountain can not shake, it is difficult to occur soil erosion, equivalent to the frame of the building will never shake due to soil erosion, such a "concave" structure also built a windshield bay, no matter how strong the wind blows outside, can not blow on the building.

Wind and sand erosion, soil erosion, flowing water erosion, gravity change, if these factors cannot affect the building, it is no problem that the Beifu Yiguan mound can be preserved for four or five thousand years!

Speaking of this, Song Siyuan sighed: "Just like the hanging temples we have seen, they can be preserved for so long, it is to avoid the erosion of natural factors on the building, in order to extend the life of the building as much as possible, enough to show the architectural wisdom of the craftsmen of the Northern and Southern Dynasties, far above modern people." ”

With that, she motioned for everyone to turn around and look into the distance, where they were located was the highest peak of the Onifang Basin, and through the unobstructed perspective of the gentle slope, their field of vision was unusually wide, and they could easily see the three large and small basins that surrounded them.

In addition to the basin where the cantilever hall is located, the other two basins are also in full view.

These two basins are the ancient country of Ghost Fang described by Mrs. Kui!

At this moment, the city of the two basins looks like charcoal fires burning into ashes, all of them are black and swarthy fragments of size, each fragment is a courtyard or a temple, after thousands of years of weathering, most of them do not even exist in the broken walls, and only by relying on the dense and well-organized foundation, can we judge that the mounds and stones on it used to be the residence of a certain ghost person.

The whole basin looks gray, full of dark marks, and there are not even weeds, which is undoubtedly curious.

"If you look at the buildings of the Ghost Fang people, they have weathered like this for thousands of years, and the hanging clothes mound we see is still so strong, this truth should be more clear."

"Just!"

Song Siyuan's words changed: "Even if it was burned by fire at the beginning, after thousands of years, vegetation should appear, how can it still be like this." ”

I am afraid that only Mrs. Kui knows about this problem, and everyone looks at this old lady.

Mrs. Kui went on to explain: "These towns were burned by divine fire. ”

"Divine fire?"

The crowd motioned for them to continue, lest any details be left behind.

Mrs. Kui was obviously a little frightened when she mentioned this: "The divine fire is an inextinguishable fire, it is rumored that it can not only incinerate the human body, but even the soul of the person will be burned away, once it is contaminated on the body, even water cannot be extinguished, I heard the elder mention that when the Heavenly Pupil God was angry, the river in the basin suddenly ignited the divine fire, burning all the ghost people who did not escape to ashes." ”

"What does that Divine Fire look like?" Yue Guanchao became curious.

"It is a viscous liquid similar to ink, which is stained with no open flame on the body, even if it is just a spark, it can burn people to death in an instant."
