Mountains and rivers are thousands of miles away, and the city is a nine-fold gate. The pen %fun %pavilion www.biquge.info does not see the imperial palace strong, and knows the son of heaven.

Chang'an is located on the south bank of the Weihe River in the Guanzhong Plain, which is known as the "Eight Hundred Miles of Qinchuan", the south is the Zhongnan Mountain in the middle of the Qinling Mountains, the mountains are stacked on top of each other, steep and steep, it is a natural barrier, and the north has the Beishan mountain system that stretches out in the north, and the Qinling Mountains are far away from each other.

On the large fertile plains drawn out of these mountain boundaries, the waters of Jing, Wei, Ba, and waterlogging are surrounded and lingering, and irrigation is convenient. It is precisely because of these strategic and economic favorable conditions that Chang'an has been favored by successive monarchs since ancient times.

The Zhou, Qin, Han, Western Jin Dynasty, Former Zhao, Former Qin, Later Qin, Western Wei, Northern Zhou, Sui, and later Tang Dynasty all had their capitals here.

Today's Chang'an City, in fact, is called Daxing City, which is a newly built capital city after the establishment of the Sui Dynasty, and later the Tang Dynasty built and expanded it to make it more magnificent and magnificent.

Chang'an City is composed of three parts: the outer Guo City, the palace city and the imperial city. Miyagi and the Imperial City were the residences of the imperial family, while Guocheng was a place where the common people lived together, each with its own layout.

Thousands of houses are like a game of Go, and the 12th Street is like a vegetable field.

Chang'an Guocheng has a total of 11 streets in the north and south and 14 streets in the east and west, which are divided into 110 squares in a criss-crossing manner. The most spacious is the Zhuque Street of Luoyang Heavenly Street, which is as wide as 40 zhang, and its scale can be imagined, and it is indeed the first city in the world.

When Cao Xu entered the city, it was already sunset.

At this time, he was ragged and barefoot, and after being reborn, Jindan and his body were further compatible, and Shenhua was introverted. If you don't have a pair of fiery eyes, you will never see anything unusual, and you will only treat him as an ordinary beggar.

Walking along the long street, there are locust trees on both sides of the avenue, but in the cold winter, the dense foliage has long been replaced by ice hanging, which makes people feel the majesty of midwinter.

However, the severe cold weather did not affect the prosperity of Chang'an.

After Cao Xu walked forward with the flow of people for a while, he took out some broken silver from his body and walked towards a middle-aged man standing on the side of the street.

The man's brows furrowed, and he was about to walk away, when he suddenly saw the silver in Cao Xu's hand out of the corner of his eye, and suddenly stopped.

Cao Xu walked closer, bowed his hand, and said: "This eldest brother, I met bandits on the way to Chang'an, and I was separated from my family, I only know that my relatives live near the Yuema Bridge, can you take me there, these silver are considered deposits, and when I find my relatives, I will definitely be thanked." ”

The middle-aged man looked Cao Xu up and down a few times, with fine skin and tender meat, elegant conversation, although the clothes on his body looked tattered, but with a pair of divine eyes that he had practiced in the market for many years, he immediately recognized that the material was definitely the top, and he immediately believed what he said just now.

The Prancing Horse Bridge is also known as the Rich Bridge, because both sides of the bridge belong to the places where wealthy merchants and nobles live.

"It's a good deal, and maybe you can get in touch with a nobleman or a wealthy businessman. The middle-aged man was overjoyed, and after reaching out to take the broken silver in Cao Xu's hand, he replaced it with a smile and said: "The Yuema Bridge is next to the West Market, this son, please come with me." ”

With a local snake leading the way, walking through the streets and alleys, the two soon came to Chang'an West City.

The West Market is brightly lit, reflecting the nearby streets as bright as day, and the four main streets with a tic-tac-toe layout are full of shops from all walks of life, in addition to selling local products and department stores, other treasures are also available, and there are wine shops and restaurants on both sides. Pedestrians rub shoulders together, so it's not lively.

All the way forward, after passing Yankangfang, the two turned left to Yongan Street, and the Yongan Canal, which is more than ten zhang wide, crosses the north and south, and flows in front. Yong'an Canal connects to the Wei River in the north of the city, supplies half of Chang'an's water, is a water transportation artery, and is also the largest artificial canal connecting the north and south of Chang'an City.

The Prancing Horse Bridge spans on it, and the bridge body is built with carved and delicate stones, and the span reaches more than ten zhang, which can accommodate four cars in parallel.

The stone carved railing on the bridge is carved with a bas-relief of cloud dragon pattern, and the six pillars in the middle are different from other pillars, which are six stone dragon heads that overlook the outside of the bridge.

"Yang Gong's treasure house, the relics of the evil emperor. From today onwards, it is all in my pocket. Cao Xu looked at the Prancing Horse Bridge not far away and smiled. Even if these things are not useful to oneself, it is better than falling into the hands of others in the future.

Then, he patted the middle-aged man on the shoulder and said, "It's hard for this big brother, it's cold at night, so you better go home early to rest." ”

The middle-aged man nodded, turned around and walked back.

After walking for a while, the middle-aged man's feet suddenly stopped, he touched the broken silver in his arms, and tried to recall the previous events, remembering that it seemed that he had met a person, and then took him to a certain place, what kind of person he was, and where he went, but he couldn't remember anything.

A cold wind blew, the middle-aged man shivered, there were not many people on the street in the four corners, there were enough shadows, he didn't dare to think about it anymore, tightened the clothes on his body, and left quickly.

Cao Xu came to the side of the Yuema Bridge, found a remote corner and lay down, and the strong spiritual power poured out like a tide, spreading in all directions.

For mechanics, Cao Xu only knows a little about the surface, so he directly opens the hanging, as long as the structure of the Prancing Horse Bridge is clear, he is afraid that he will not be able to open the mechanism.

After a while, the structural model of the Prancing Horse Bridge appeared in Cao Xu's mind. After pondering carefully, after more than an hour, he finally found a way to open it.

Tonight, the moon is high and the wind is dark, and there are no pedestrians on the streets for a long time.

After waiting under the bridge for a while, the drumming of the second watch came from Xishi, and a team of patrols walked across the Yuema Bridge, went south along the Yong'an Canal, and gradually moved away, taking away the light of the lighting lanterns, and the darkness engulfed the Yuema Bridge again.

Cao Xu walked up to the bridge generously, and the six pillars in the middle of the Prancing Horse Bridge were shaped as stone dragon heads looking out of the bridge, which was where the mechanism was. Touching the six dragon heads, he moved quickly, and after a while, he turned on the mechanism.

After turning around, the six dragon head pillars in the middle of the Prancing Horse Bridge all fell back to their original places, and their positions were not bad at all.

At this moment, a slight shock came from below.

Cao Xu looked under the bridge, and saw strange ripples on the surface of the river, and bubbles came out, and a subtle sound was heard.

However, the movements were not very violent, and the time was short, so they were not serious.

The mechanism is open, but the entrance is not here. For Lu Miaozi, who built this underground treasure house, Cao Xu felt quite admired.

When he had previously explored the structure of the Prancing Horse Bridge, he had already grasped the bearing. At this time, without delay, he immediately walked towards the entrance.

The entrance to the underground treasury is the backyard of a mansion. Cao Xu soon saw the courtyard wall, and immediately performed light skills and entered the courtyard.
