My brother is so cunning.

Abyss Sea City is located in a trench southeast of Dragon Palace.

Compared with several other large cities, this place is the aquatic city with the worst lighting.

For example, Coral Sea City is located in the coastal coral reef area. The water depth is only 35 meters. People living there are some shallow-water marine people. During the day, it really feels like Bikini Castle underwater.

Jingluohai City is located on a submarine plain 700 meters underwater, and sunlight can barely reach it.

Only the abyss in the trench, with a water depth of five thousand meters, does not see a ray of sunlight all year round.

But this sea city was not completely dark in the past. Deep-sea creatures have evolved light-emitting organs, and the bones of these creatures after death were collected as lighting tools.

However, this is only better than nothing, so many residents of the sea city have poor eyesight and rely on their sense of smell, hearing and perception to survive.

This kind of deep-sea city is not suitable for biological survival, but the ocean is vast and there are many kinds of creatures that can adapt to the pressure of the deep sea. Since there are few natural enemies, they are not affected by human fishing, but they grow to huge sizes and have long lifespans.

There are many deep-sea creatures that have opened up their intelligence, and they gather together to build huge underwater cities.

Compared with Abyss Sea City, the living environment in Coral Sea City is indeed better.

However, because it overlaps with the activity areas of terrestrial life, shallow-water marine life suffers greatly from fishing and plundering, and its habitability does not seem to be as good as that of the abyssal sea city.

Two oarfish spirits swam their slender bodies with shining silver, dived into the abyss and trench, and arrived at this underwater city.

These two big hairtail fish are actually the transformation of the father and daughter Dragon King Ao Guang and Dragon Girl Ao Lan.

After hearing from his subordinates that the lighting projects in the four sea cities had been completed, Ao Guang, at his daughter's suggestion, transformed into the form of an ordinary sea monster and went to Abyss Sea City incognito for a private visit.

The Dragon Girl advised the Dragon King, saying that the city surnamed Wen was too deep and a series of actions had ulterior motives.

It’s better not to be blinded by vanity, as an ordinary seaman, experience the changes he has brought about, and then make a decision whether to support his submarine lighting project platform.

Ao Guang also listened to the advice and became the king of the water tribe for many years, although his level of governance was only that much.

——The Poseidon of the Far West has built the black technological civilization of Atlantis, and he is still guarding the Crystal Palace as a treasury manager for various powerful people.

The Dragon King is not very good, but he is experienced and understands the world. Ao Guang also feels that Wen Rui is so "kind" and it is suspicious.

From a certain perspective, it is easy to deduce this simple truth based on the experience of being a dragon for many years.

That means not bullying the immortals and gods of the Dragon Clan. There is definitely something wrong!

Two big hairtail fish swam into the trench and were immediately blinded. At first glance, it was almost impossible to recognize that the brightly lit and neon underwater cyber city below was actually the original dark abyss city with only a few glimmers of light.

Arriving at the sea market, Ao Guang, as the Dragon King, who was used to seeing mountains of treasures, couldn't help but be speechless.

"Master Wen, are you showing off your wealth to me?" Ao Guang said to the Dragon Girl beside him: "The Dragon Palace only contains one hundred thousand pearls and is known as the number one Dragon City in the three worlds, five oceans and four seas. This city is at least... It contains millions of colorful pearls! Are pearls on land so worthless?”

"Father, the kind of beads Wen Rui took out are not night-light pearls at all."

The Dragon Girl explained in the Dragon King's ear: "My daughter has taken down a few of them for study. They are more like creations made by skilled craftsmen. They are all made of ordinary things. They only follow some kind of heavenly principles, so they can emit colorful light after being powered on."

"However, it is used the same as the Luminous Pearl, and the light it emits is brighter than the Luminous Pearl. It is not that the Luminous Pearl is better than the Luminous Pearl, and the price will not be cheaper."

Ao Guang shook his hairtail head and said, "By the way, didn't you lose to Wen Rui in a bet and join the Jie Jiao? Did the books he gave you contain instructions on how to make colorful pearls?"

"Uh..." Dragon Girl said with shame: "My daughter has only been studying for a short time and has not yet fully understood it. It does mention the principle of 'electric light' lighting, which is to convert electrical energy into light energy. That set of books is profound, comprehensive and all-encompassing. The author is the leader of Tongtian Cult, and you still need to study hard and understand it carefully to get the essence. "

Two hairtail fish were wandering the streets of Haishi, and many light poles could be seen erected on the seabed. Each light pole was equipped with a large "pearl" that emitted incandescent light. A single pearl could illuminate a large dark area.

Strings of colorful small lamp beads are also arranged on the outer walls of the surrounding sea city buildings, changing colors regularly.

Landscape lights are even buried under the corals on the roadside, undersea heating pipe columns, and sea animal skeletons.

What's even more exaggerated is that at the intersection of the city's main streets, there are projection headlights that project a three-dimensional light image, like a giant glowing sculpture.

The lighting project of streetscapes and public areas has been completed, but there are still many puppets wandering around the city carrying out lighting projects in homes.

As long as Shuizu citizens pay deep-sea ores, pearls, and gems, they can purchase a certain amount of electricity. The lighting project maintenance base station of the Chamber of Commerce will send metal puppet workers to their homes for free to install lights.

In fact, Wenrui lights up the streets of the four major cities for free. The ultimate goal is to sell electricity to Shui residents. When installing street lights on each street, it has already begun to lay out a city-wide power transmission network. It only takes Just pull a waterproof wire from a nearby street light.

The two big hairtail fish were like Grandma Liu entering the Grand View Garden, looking around the city, and unknowingly came to a newly built metal frame high-voltage resistant building.

At the entrance of the building with a metal exterior, the words "Golden Spiritual Sect Office in Abyssal Sea City" were spelled out in neon lights, and there was a line of small words "Chamber of Commerce Experience Hall in Abyssal Sea City" behind it.

This building spent a lot of money to inlay many water-repellent beads at key locations on the exterior wall. The invisible force field pushed away the high-pressure water flow, forming a waterless space in the deep sea.

It is easier to spend some spiritual stones to buy water-repellent magic weapons than to use technological means to build a base on the seabed. When Wen Rui was designing the seabed base, he did not hesitate to use technology. As long as the cost allowed, he would do it in any convenient way.

If it is technological means, the huge water pressure is not easy to solve, but unscientific things like water-repellent beads can ignore the water pressure and create a waterless space.

The two big hairtails looked at each other, and the fish tails turned into two legs, and walked into this novel metal building.

As soon as they entered the building, a mermaid girl in a short skirt uniform came to the door. She bowed to the two hairtails in a very businesslike manner and said with a smile: "Welcome! Two distinguished guests, are you here to experience the latest underwater home appliances of the Chamber of Commerce?"

Ao Guang glanced around and saw that there was a hall at the entrance. There were many men and women in uniforms busy in the hall. There were also some visitors from the aquatic tribe following the mermaid employees to experience the so-called "underwater home appliances".

The shop opened to the bottom of the sea, and Wen Rui did not plan to arrange for the human employees of the Chamber of Commerce to be stationed there. After all, the water pressure was somewhat harmful to the human body, and the employees were also prone to drowning and death.

So, through the introduction of Li Moxian, a large number of mermaid employees were hired in the Lishui mermaid tribe, and after training, they were sent to the four major sea cities to serve.

In this way, the mermaids had income security and were much farther away from the mainland, reducing the covetousness of many land monks who were interested in mermaid pearls and mermaid flesh.
