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.

Among them, three north-south avenues and three east-west avenues between the city gates constitute the traffic backbone in Chang'an City, the most spacious of which is the Zhuque Street of Luoyang Heavenly Street, which is as wide as 40 zhang, and the rest are not as wide as the Zhuque Street, its scale can also be imagined.

In addition to Zhuque Street, Chang'an is most famous for its Metropolis and Liren City, which are located in the southeast and southwest of the imperial city, each occupying two squares.

There are four streets in each city, forming a cross-"well" shaped layout, dividing the entire city boundary into nine districts, each district facing the street on four sides, and shops of various industries are set up on the street. Within each district, there are still small lanes, which are convenient for internal passage. The two cities are the most lively places in Chang'an City, and many restaurants are open all night, which is a prosperous resort in Chang'an City.

Walking on this main axis that runs through the north and south of Chang'an City, how can I feel unrelieved in my heart, thinking that after going through dangers and obstacles, and even almost dying, I finally arrived here, that feeling is really indescribable.

In order to prevent water accumulation, drainage ditches are set up on both sides of the main street in the city, which are as wide as a small river, and stone bridges are paved at the intersection of road and water ditches, forming a characteristic of Chang'an.

On both sides of the avenue, there are locust trees, but in this cold winter, the dense branches and leaves have long been replaced by snow and ice, which makes people feel the majesty of midwinter. The severe cold weather did not affect the prosperity of Chang'an.

On both sides of Suzaku Street, whether it is a shop or a residence, it is a large mansion with a large regulation and a large courtyard, with a courtyard and a hall.

The houses in the alleys are tiled-roofed and white-walled, and the single-storey structure is arranged in rows of streets and alleys.

The door of the house is mostly decorated with exquisite tile and wooden doors, and the high walls are deep in the courtyard. The roadway is deep and long. It's very different from the bustling streets. Tranquility and peace. The houses of the wealthy families are extremely gorgeous and majestic, and the equipment of the shops is also full of ingenuity, such as barrels and beams, exquisite carvings, or beams interspersed, bucket arches out of the eaves, and different regulations.

Lin Chen walked and walked and stepped on the long street. The metropolis is prosperous and prosperous, and the lights are as bright as day, which is worthy of being the famous capital of Dayi. The four main streets in a tic-tac-toe shape are lined with shops from all walks of life, including local groceries and other treasures.

Pedestrians rub shoulders together, so lively, this kind of excitement is not much better than reality, and even more different kinds of fun.

Lin Chen turned into the street between Kaihuafang and Anrenfang. Walk towards Anhua Street, which runs parallel to Suzaku Street to the forest gate in the north of the city and Anhua Gate in the south of the city, and cross the stone bridge that crosses the Qingming cuisine. Cut into Anhua Street, which is listed as Chang'an Sixth Avenue along with Zhuque Street.

The glorious lights of the West Market. Reflecting the daytime in the vicinity, pedestrians, cars and horses come and go, and the atmosphere is lively. After passing through Yankangfang, Lin Chen 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. A magnificent large stone bridge over the aqueduct.

Looking at the stone bridge in front of him, Lin Chen felt in his heart that he was so close to the Evil Emperor Relic, and this stone bridge was the Prancing Horse Bridge.

However, looking at the boats coming and going in the Yong'an Canal, Lin Chen secretly frowned, planning to wait until the third watch to take advantage of the hazy night.

After walking around for a while, although it looked like he was playing, Lin Chen was secretly observing the surrounding environment, preparing for himself to open Yang Gong's treasure house.

I don't know how long it took, Lin Chen already had an understanding of the surrounding environment, and Lin Chen left this place.

After leaving, Lin Chen wandered around the street for a while before returning to the inn.

At the third watch, a figure jumped out of the inn, discerned the direction, and disappeared into the hazy night like a ghost.

Chang'an Leaping Horse Bridge, today the sky is shrouded in black clouds, there is no light at all, came to the Leaping Horse Bridge, Lin Chen jumped under the bridge, opened the ground button lock of the six faucet switches on the control bridge, and then opened the six faucet switches in an accurate way, after the last faucet was opened and returned to its original position, only to hear a "click" sound, the entire Prancing Horse Bridge trembled gently, and Lin Chen knew that the entrance to Yang Gong's treasure house was opened.

At the beginning, Kulu Miaozi built the Yang Gong Treasure House and built four tunnels, one of which could directly reach a hill outside the city, the second tunnel led to the bottom of Dugufu's mansion - Xijiyuan, the third led to a house formerly called Shafu, and the last one led directly to Yong'an Canal.

However, when Lu Miaozi was designing, the entry switches of the four tunnels were covered, and the main switch of the Prancing Horse Bridge must be turned on before the entry switches of the four tunnels appeared.

When the Prancing Horse Bridge switch is turned on and the Prancing Horse Bridge trembles slightly, it is a sign that the entry switches of the four tunnels are opened.

Lin Chen didn't wait for this tremor to stop, he immediately jumped out and went straight to the entrance of the treasure house of the Dugu Valve Xiji Garden. Lin Chen performed Ling Bo micro-steps, quickly jumped over the high wall of Xiji Garden, quietly came to the backyard, and found the north well very smoothly, and then jumped into the well. However, this well was very deep, and it was difficult for even daylight to enter it, and it was also night, even if Lin Chen had an ability in the water, his vision here would be greatly affected.

Lin Chen slowly dived to the bottom of the water, groped at the bottom of the well for a while, and felt a stone that protruded from the wall of the well, and pressed it hard.

Immediately after that, a "rolling" sound was heard, and the wall of the well slowly sank down, revealing a passage that could only pass one person.

Lin Chen took the lead, quickly swept over a distance of two zhang, and plunged into the well, now it is winter, and the well water is cold and biting, but Lin Chen's innate true air rotation in his body did not feel the biting chill.

When he held his breath and sank to the bottom of the well, where the light was hard to reach, and in the water, it was also late at night, and his vision was useless, and he could only act by feeling.

Lin Chen kept groping for the wall of the well at the bottom, and after groping for a while, a stone protruded from the wall of the well, which was completely different from the completely smooth wall of the well, Lin Chen was overjoyed in his heart, and found it, Lin Chen immediately pressed the stone that was half a foot square.

The sound of "rolling" is piercing in the narrow space at the bottom of the well, and at the position of the water surface of the well, the wall of the well slowly sinks down, revealing an entrance that can only allow one person to pass through.

Lin Chen leaned against the wall and burrowed into the small dark square hole.

The passage first stretched upwards obliquely up to five zhang, and then changed to downward oblique extension, and it was quite steep.

The walls of the secret passage were surprisingly not overgrown with plants that like wetness and darkness such as mosses, and the air was so stuffy that it was suffocating, Lin Chen immediately converted his external breathing into internal breathing, and simply walked with his breath as if he was under the water.

After walking down on his knees for more than ten zhang like this, Lin Chen suddenly stopped, and another button appeared on the stone wall.

Lin Chen looked at this button and thought carefully for a moment, and then walked forward regardless of it. (To be continued.) )
