In the ancient city that has almost completely collapsed and collapsed, a floating tower can still stand for a thousand years, which at least proves that the material of the floating tower is very strong, can resist the invasion of wind and sand for nearly a thousand years, and then look at the fall of other buildings around the floating temple, everyone will understand that there must be strange and strange in this floating tower.

"It's time for work, let's clean up the floating slaughter first, and see what kind of material it is, so resistant to tossing."

Yue Guanchao signaled to Xu Xiake, and everyone took out their sapper pickaxes and began to clean up the loess seal, this type of floating slaughter is mostly a solid tower body, covering an area much smaller than the pagoda that can enter and exit in later generations, and the widest base of the tower is only the length and width of the roof.

After they dug up the loess seal layer of the tower base, they quickly cleaned up the foot of the pagoda and the tower body, Song Siyuan carefully observed the tower body and the tower base that were cleaned out, the material of the tower base is a very common giant gray stone, and the part that reaches the foot of the tower can already see the metallic luster.

Observe carefully, the surface of the oval tower foot is distributed with a regular array of rivets, the material is similar to the dark iron, to the tower body becomes a brass material, after being eroded by the wind and sand, the appearance has a patina rust, take the sapper pickaxe to knock the tower body, the sound is low and clear, trembling, it can be seen that it is not a hollow material, probably a solid pouring.

On the brass tower, from the traces of patina, it can be seen that there are many red Sanskrit characters painted on it, which looks as if it is evenly carved along the tower body, completely wrapping the tower body.

They were curious about what these things were, and Wang Yuanqi then hurried behind them.

"Daoist Wang, why don't you look at the camels, why are you running here?" Keli asked when he saw Daoist Wang coming over.

Wang Yuanzhen waved his hand: "These camels have that little brother watching, it's useless for me to be there, just come over and have a look, just now I heard a faint chanting sound in these voices, maybe there is an old Taoist priest who can help." ”

He picked up the dagger, scraped off the yellow sand left on the tower, and explained: "At that time, in order to study the Buddhist scriptures, I also learned Sanskrit from the monks near the Thousand Buddha Caves. ”

"In order to ensure stability and solidity, the foot of the tower is made of iron, which is the high-quality steel of the Sui and Tang dynasties, which can be done for thousands of years without corrosion and rust, this kind of iron is also used in the production of Mo knife, that restrains the Hu people, the Mo knife that is broken by people and horses, is forged with bin iron, it can be said that the same volume of iron is basically equivalent to the same volume of gold, as for the body of the tower and the top of the tower, most of the refined brass is used!"

Wang Taoist priest then carefully analyzed the Sanskrit on the tower: "The content of Sanskrit is mostly the name of the monk, the sponsor, and the craftsman who built the floating tu, and then there are some prayer scriptures or something, judging from the content of these Sanskrit, it was probably built in the late Tang Dynasty and the Five Dynasties period, when this was no longer the territory of the Tang Dynasty, it was occupied by the Tubo State, and it was the Tubo State that organized the people to build the blessing Futu in this city. ”

Song Siyuan nodded: "That's right, the style of this floating temple is very similar to the lama temple in Tibet, and there can be such a floating temple, which proves that this city is indeed influenced by the architectural culture of the Tubo country......"

The history mentioned by Wang Yuanzhen has a close causal relationship with the decline of the Tang Dynasty.

Since the beginning of the Zhenguan period, the Tang Dynasty opened the Silk Road to annex the Western Regions, since then, the vast Western Regions including the Green Mountains of Central Asia in the west, the Tianshan Mountains in the north, the Turkic steppe in the east, and the snowy Kunlun Mountains in the south, all of them were swallowed into the territory by the Tang Dynasty.

At that time, the Hu people of the small countries in the Western Regions all regarded the Tang Emperor of Chang'an as the heavenly khan, worshiped the kingdom from afar, respected Zhengshuo, and regarded it as glory to be able to go to Chang'an to be officials, trade, and exchanges.

In the fourteenth year of Tianbao, Yuyang Mo came agitated and broke the song of neon clothes and feathers.

An Lushan wrapped around the three towns of Heshuo elite soldiers, in the east of the river to rebel, the news spread to Chang'an, Tang Ming Emperor and the concubine with the royal family, civil and military ministers fled to the wind, during the period and experienced the change of Ma Weipo, Yang Guifei was strangled by the stagnant rebels, Tang Ming Emperor after several upheaval and displacement, then fled to Shu for refuge.

This farce kicked off the prelude to the decline of the Tang Dynasty, and also sounded the death knell for the Tang Dynasty!

In that year, Emperor Tang Ming was very happy and liked good news, in order to let the border town military general open up his territory, the right to recruit soldiers was delegated to the feudal town, and then the power of taxation and official appointment and dismissal was opened, making the border town a country within a country, and the power and responsibility were too centralized.

Under this system, An Lushan concurrently served as the envoy of Youzhou, Weibo, and Chengde three towns, with 200,000 soldiers and horses, all of whom were able to go into battle to kill the enemy and defend the territory.

This person is most afraid of Li Linfu, and when Prime Minister Li dies and Yang Guozhong becomes prime minister, no one can suppress An Lushan, of course, he will be coerced by Hedong and raise troops to rebel.

In contrast, most of the government soldiers in the Guannai are old, weak, sick and disabled or street slickers who recruit cats and dogs, and they usually oppress the people, but when they encounter the Hedong drought soldiers who have really fought on the battlefield, they are cut off and can't find the north, and the defense line in the Guannai is of course a thousand miles away and cannot be defeated.

However, in a few months and a half, An Lushan has broken through Luoyang, directly enthroned in Luoyang and called the emperor, the old Tang Ming Emperor was not there, so he retreated in Shu and no longer went out of the mountain, the prince Li Yu took advantage of the chaos to ascend the throne in Lingwu, and urgently recalled the Hexi soldiers who were protected in the capital of Anxi, which allowed the defeated Tang army to pull back a game.

As the old saying goes, flies don't bite seamless eggs, when the elite of Hexi was transferred to Guanzhong to quell the rebellion, there were basically only the remaining Hexi soldiers left in the land of Anxi.

This person with a heart is a Tibetan person.

Probably not long after the Anshi Rebellion, the Tubo people took advantage of the Guannei to quell the chaos in Hexi, took the opportunity to come down from the snowy plateau, and directly occupied the west end of the Hexi Corridor, which was equivalent to cutting off the neck of the Hexi Corridor that connected the Western Regions.

In the following forty years, the Tubo State used troops for many years to protect the former capital of Anxi in the Tang Dynasty, and finally encroached on the land of Anxi, not to mention any dangerous wars during the period, the final result of Hexi was completely occupied by the Tubo people and became the territory of the Tubo people.

Located at the western end of the Hexi Corridor, this town is estimated to be one of the cities occupied by the Tubo people from the Anshi Rebellion to the end of the Tang Dynasty.

"Since it is to pursue solidity, why not pour the body of the tower with iron, so that it is easier to preserve?"

Yue Guanchao looked at the tower body, the foot of the Xuantie tower basically did not have any feeling of corrosion, only the tower body made of brass was seriously corroded, if it was not for the solid copper pouring, it is estimated that it would have collapsed long ago.

Wang Taoist explained: "The old Taoist priest guessed that it should be for the seal to engrave Sanskrit, the iron is too strong to carve too many words on it, but the brass is different, it can be engraved with words, and again, although these towers are solid pouring, the position under the tower is according to the system of the Futu Tower, probably a niche under the tower, which can be used to recite the scriptures and worship relics. ”
