Cultivation till the end of time

"Master, the road ahead is impassable and the bridge is broken." At this time, Manman found that the road ahead was impassable and stopped by the roadside.

When Duoduo heard him say that the bridge was broken, he raised his head and looked at the broken bridge he pointed to. When you see the situation ahead, Duoduo is left with nothing but black lines, isn’t that called a broken bridge?

In fact, the bridge in front is not broken, but a tunnel is dug from the river bottom in the middle of the bridge. When vehicles reach the middle, they pass through the river bottom tunnel.

This is to make it easier for ships to pass through the river. Generally, ships pass under the bridge, but the design of this bridge is that ships pass through the middle of the bridge. This facilitates the navigation of large ships without the problem of limited height.

Duoduo has read the news before and knows that there are many unique bridges or buildings in China that are built to attract tourists, and this bridge is like this.

Its characteristic is that vehicles drive on bridges on both sides from high to low to the intersection of rivers in the middle. When vehicles reach the place with river water, they enter the tunnel and reach the opposite side from the river bottom tunnel. This tunnel can only be seen from the bridge, but from the side, it looks like the bridge is broken, and there is no tunnel visible at all.

Duoduo looked at Manman speechlessly, which really confirmed the argument that being uneducated is terrible. Duoduo was no longer angry about what he had just said, and looked at him with some sympathy. At the same time, we started to popularize science and tell everyone about the extraordinary features of this bridge.

After listening to Duo Duo's popular science, I could only smile awkwardly. There was no way, he couldn't extend his consciousness all the time, and it was understandable that he couldn't see the universe inside the bridge.

When Manman drove to the bridge, looking from a distance, everyone did see a cave extending downward on the bridge (to Ling Yun and others, the tunnel looked like a cave.). Directly above the cave is the river.

It really proves what Duoduo said. The bridge only looks broken in the middle when viewed from the side. You can see the tunnel when you look at it from the bridge.

Manman muttered: "Why does it look like it's broken? Who knows what kind of tunnel there will be under the bridge."

Duoduo heard his muttering and refuted him: "This is called urban planning. Such characteristic bridges can serve as special local scenery and can be used to attract tourists to come here.

Moreover, this kind of bridge can also take into account the simultaneous movement of boats and vehicles, achieving higher efficiency. Some bridges are disconnected in the middle and raised to both sides to allow ships to pass through the disconnected part. However, this type of bridge can only accommodate the passage of one vehicle, unlike this bridge, which can accommodate both sides. "

"Then as long as the bridge is built higher, ships and vehicles can pass through at the same time." Gungun put forward his own opinion.

"You can only say that if you have never seen large ships and cargo ships. The hulls of those ships are very tall and wide, and many factors must be considered, including the draft capacity of the river, the length of the bridge, the supporting capacity of the bridge body, and A higher bridge can only be built if there are issues such as the stability of the bridge pier foundation.

Anyway, building a bridge is not as simple as imagined. However, there are still many bridges in China built very high to allow ships and vehicles to pass at the same time. It’s just that the kind of bridge we see now is relatively rare. I can only say that it is a local feature, in order to attract more people to come here to watch the tour. "

"If I have the chance, I really want to see those bridges you mentioned and see what they look like." Yi Lai said with interest.

"I have also seen a kind of bridge on TV. That kind of bridge is full of technology. The bridge is built very low and is very close to the water. There is a ring road in the middle of the bridge. There are four rings in the ring road. Pier supports.

The edge of the ring road is also connected to the top of the bridge with a lot of bridge welding materials. Whenever a ship wants to pass here, the ring roads on both sides will rise to the top of the bridge, thus forming a large arch bridge to facilitate the passage of ships.

Since there are also two large piers there, there are size and height restrictions for boats. But every time I see the ring road rising automatically, I feel amazing.

When a ship or cargo ship is about to cross the bridge, the lanes on both sides of the bridge will flash yellow lights in advance, then turn on red lights, and the cars will stop to let the ships pass first. "Duoduo remembered the bridge she had seen on TV and couldn't help but praise it.

"What is TV? Why does the yellow light flash first and then the red light? What does this mean?" Gungun asked the question he discovered.

"Oh, I forgot to introduce, there are many traffic rules in this world, the most common of which is to control the traffic flow according to the traffic lights.

When we were kids, we used to sing: Stop on red light, go on green light, and obey the traffic rules. There is also a yellow light that lights up as an advance warning, prompting you to prepare to switch to other lights. However, these traffic rules only apply before the end of the world, so I don’t need to say more about them now.

As for the TV, it is a square machine with many various videos to watch. It was only useful before the end of the world, but now it is just scrap metal and nothing can be seen.

The video is like the Mysterious Mirror Technique in our world of cultivation. You can see the images inside and so on. The only difference is that the TV videos are all shot in advance, while the Mysterious Mirror Technique is live broadcast. "

Duoduo couldn't help but sigh with emotion, the end of the world will really change the world. All the original order was broken, leaving only a mess.

"It feels like this place must have been prosperous before the apocalypse, but now it just feels dilapidated." After listening to Duoduo's popular science, Yi Lai couldn't help but sigh when he looked at the dilapidated buildings around him and the ground filled with garbage and blood-stained corpses.

"Stop the car and don't get on the bridge first. There is something in the river." Suddenly Ling Yun warned.

Manman immediately stepped on the brakes, and everyone leaned forward with inertia. They all looked up at Ling Yun, waiting for his explanation.

"Don't just chat, you should be more vigilant. Haven't you noticed that there are very few zombies around here? My spiritual sense detected something swimming in the river, and it is approaching us quickly." Ling Yun scolded everyone for their carelessness, and then put his Discover and tell.

Fatty's voice sounded in Duoduo's mind at this time: "Sister, the level of mutants in the river is about the same as mine. You should be careful."

"Don't worry, we will take care of it." Duoduo comforted Pangpang and took out a handful of panda hair.

"Master, senior brother and I have passed a bridge before, and there were many mutant fish under the bridge. Could it be the same here?" Gungun thought of the bridge he walked on before to get rid of Brother Kun.

"No, that object doesn't look like a fish. It has limbs, a long and flat mouth, and uneven skin. It can swim flexibly in the river. The most important thing is that it is the only living thing in the river." Ling Yun denied Gungun's words. guess.

Duoduo heard Ling Yun's detailed description and felt that she should know the species of the mutant. Although it was a bit far away, Duoduo still tried his best to reach the vicinity of the river with his spiritual consciousness. When the mutant came into her range, she saw exactly what she had guessed.

"I think I know what it is."

Everyone heard Duoduo say they knew what it was, and everyone looked at her.

"That should be a mutated crocodile. Its appearance is similar to what I remember, but it is bigger than before. Everyone, please be careful, this kind of thing can crawl on land, and its bite is very strong." As if to confirm her words. , the mutated crocodile suddenly burst out of the river.

It had long sensed that there was food for it at the intersection on the opposite side. But they stopped, and it couldn't wait for them to come over, so it burst out of the water and crawled towards them.

When everyone saw it crawling over quickly, they all opened the door and got off the car. Now, staying in the car will do no harm, but going outside will make it easier for you to unleash your power.

As soon as they put the car away, the mutant crocodile crawled in front of them. The mutated crocodile swung its tail towards where they were standing. Before the opponent's attack could reach them, everyone jumped away from each other and took out their weapons at the same time.

This time, Pangpang also showed off his level of coercion. The mutant crocodile felt that the little thing on the opposite side was as powerful as him, so he changed his route and attacked Pangpang specifically.

The idea of ​​the mutated crocodile is very simple, that is, if it eats Pangpang, it can be upgraded again.
