Bridges are mainly beam bridges and pontoon bridges, and most of them can only be built in areas where the terrain is flat, the river is not wide, and the water flow is gentle. In fact, there is a legend about Wanlou City that only the Tang family knows, and no outsiders know about it."

At this point, Tang Tang was a little confused. She wanted to tell Li Luo that most of the elders in the family had told her not to tell anyone else. She was wavering between obeying the instructions of the elders in the family and telling Li Luo the truth. It was really difficult for her.

Seeing the painful look on her face, Li Luo couldn't help laughing and said with a smile: "It doesn't matter, it's about the Tang family's secrets. It's okay not to tell them, or let's talk about the bridge..."

"No! This is not just a secret of the Tang family. Besides, besides... the prince is not an outsider." As he spoke, Tang Tang's face turned red. Li Luo's heart skipped a beat and he shuddered secretly. He might need it in the future.

You should be more careful, don't let Tang Tangfang make mistakes and waste your good years in vain.

Li Luo was thinking about it, but she didn't expect that Tang Tang misunderstood. She thought that Li Luo felt that he had deliberately concealed it, and felt unhappy. She almost burst into tears, and said with a slight cry: "I didn't mean it."

To hide it from you, they say that underneath the City of Ten Thousand Towers is actually a land of sky and water, and that the entire City of Ten Thousand Towers is floating on the water. It has been passed down orally from generation to generation of the Tang family that the City of Ten Thousand Towers is actually a huge ship."

"What!?" Li Luo was horrified, looking up at Tang Tang who was full of tears. He was slightly startled. The beautiful pear blossoms were raining, and he felt that no shocking secret could be more than this, and it could not match the tearful look of the pity, "You

Why are you crying? Don't cry, it's my fault, I have to force you to tell this secret." Li Luo stretched out his hand to touch the top of Tang Tang's head, but felt that this appearance was too ambiguous, and stopped his hand in mid-air, feeling a little restless for a moment.

He said hurriedly and firmly, "Don't worry, I will never tell anyone else this secret except you and me. Just treat it as, uh, a gentleman's agreement between you and me."

Tang Tang sniffed, opened his mouth slightly, and felt much more comfortable. He glanced sideways at the hand that was frozen in the air, reluctantly moved his head and rubbed it under Li Luo's hand for a few times. His pretty face was slightly ashamed, and he was worried.

She was slightly red, but she felt happy in her heart. Of course, Li Luo didn't know why she was sobbing and smiling. The girl's feelings, a secret that only belonged to two people, always made people think about it. If he knew how to say it casually,

If I ask Tang Tang to think so much, I'm afraid I'll have another headache.

But the secret Tang Tang told is really unbelievable. A city and a ship are so big. Can the ship float and move? If it can move, what kind of spectacular scene will it be. Li Luo

Lei Ran is fascinated, but he knows that he probably has no chance to see Wanlou City rising up after being hit by the water. Besides, the adults of the Tang family may be tricking the children, but it is better not to say this, in case they cry again.

Yes, it’s not easy to coax.

"Where were you talking about?"

"secret."

Tang Tang puffed up his cheeks and exclaimed: "Bridge!"

Li Luolang laughed: "Yes, bridge."

Tang Tang cleared his throat and continued: "Then there are more complex bridges. The arch structure is mainly made of masonry structure system, supplemented by iron and bronze wares, so that the bridge has additional features on the basis of the log beam bridge.

With the addition of new components such as stone pillars, stone beams, and stone bridge decks, stone arch bridges came into being. The four basic bridge types of beam bridges, pontoon bridges, cable bridges, and arch bridges have all been formed. Later, it should be considered five hundred years ago, ten thousand years ago

There are many types of bridges in Loucheng, such as open-shoulder stone arch bridges, stacked-beam wooden arch bridges, bridges with raft-shaped foundations, oyster-reinforced pier bridges, stone beam bridges and opening and closing pontoon bridges, and so on.

Kit Kats are probably all left over from that period. Many of the famous bridges in Wanlou City have inherited the wisdom of predecessors at that time, expanded or repaired them. Now, in fact, original techniques are rarely seen, and they are not as good as before.

.”

Seeing her happy words, Li Luo was surprised that Tang Tang was not just a pampered lady from an aristocratic family, but actually had a lot of insight into urban construction. On the other hand, he was embarrassed to ruin the atmosphere. In fact, she had already digressed from the topic for a long time.

Fortunately, Tang Tang still remembered what Li Luo asked. He glanced at the stone bridge under his feet, pursed his lips and said: "Whether it is a wooden bridge or a stone bridge, it has pile foundations, pier bodies, beams, etc. If you want to build it well,

Bridges cannot cut corners. Regardless of size, the topography, geomorphology, geology, hydrology, wind, rain, snow, freezing, drainage, slope stability, materials, stress, environment, and landscape must be taken into consideration when constructing. They must not be dangerous and will last a long time.

It is convenient for various repairs. Putting aside the Feng Shui mentioned by the Yin Yang family, building a bridge is much more cumbersome than building a road. Look at this one. The base is unstable, the length of the arc is wrong, and the terrain is forced here.

It's still a half-length bridge. It would be fine if there was no other place to build the bridge, but this place has many easier locations to build the bridge than here. It always looks awkward, as if..." Tang Tang followed Li Luo's example and touched it.

Touching the tip of my nose, I don't know how to describe it for a while.

"A canal was deliberately built for this bridge."

"Yes, yes, it's just so awkward." Tang Tang clapped his hands and shouted.

Li Luo took a deep breath, a glint flashed in his eyes, and he guessed something. He stood on the bridge, with ditches more than ten feet deep on his left and right. The color was black, and he didn't know that it was the sediment that settled after the sludge dried up.

The color is something else, such as the mark after the blood sacrifice, which is very dark and condensed into lumps.

Li Luo closed his eyes and slowly imagined what it would look like if there was no ditch here, but only this bridge. The stone square gradually grew larger in front of his eyes, until it filled his mind. If he looked at it from a high place, the stone towers and stone platforms,

The stone bridge, as well as the stone pillars closest to the square, form an extremely common pattern, the Big Dipper array.

The Big Dipper is divided into Tianshu, Tianxuan, Tianji, Tianquan, Yuheng, Kaiyang, Yaoguang Seven Stars, Tianshu, Tianxuan, Tianji, Tianquan is composed of Dou Shen, which is called Kui in ancient times; Yuheng, Kai

Yang and Yao Guang are composed of the handle of the bucket. In ancient times, it was said that when the dipper points to the east, it is spring all over the world; when it points to the south, it is summer; when it points to the west, it is autumn; when it points to the north, it is winter.

The Canglong Qisu star chart I encountered before, the Big Dipper star chart is more widely circulated, and more people know it. But the fact that more people know it does not mean that the star chart is simple. The first of the three star charts in Caohai and Makino in northern Xinjiang is the Big Dipper star chart.

.

Because the Big Dipper is so common, the secrets hidden inside are more difficult to decipher. Tang Tang looked at Li Luo, who was in a daze, and wanted to ask him what he was thinking about, but was afraid of disturbing his thoughts and getting bored.
