The City of the Bottom, when Ling Feng saw this undersea city, he could think of the underwater city in the prequel to the war.

Although the city is in the water, there is a light mask to isolate the seawater, so the city is like an ordinary ground city.

However, this is only the upper part of the city, and the lower part is like a reflection of the city, with buildings built downward in the middle plane, and you can guess from this that this underwater city is not built on the ground under the sea, but suspended in the sea.

On the way Ling Feng just came, he had already understood the situation of this undersea city clearly, and knew that the style above was completely different from that of the Sea Clan.

Also, there are several areas in the city, each of which is connected by a passage, to be precise, bridges, because they float in the water, and there is nothing under the bridge deck, only a magic barrier on it, which can be called a sky bridge, a pedestrian bridge, according to the habits of modern people.

However, the bridge is in the air, and this bridge is in the sea, so it should be called a sea bridge. Ling Feng named these passages Sea Bridges in his heart, and it just so happened that they didn't have names either.

The five giant areas in the middle constitute the main living area of the Sea Clan in the form of a center and four rings, and in addition to these five giant areas, there are also small areas between the five blocks, or outside, these are generally special areas, such as the Sea Clan's council chamber, military area, royal area, as well as the Sea Clan's academy, alchemy area, etc.

Because of this distribution, the entire city is not a large ball, but is composed of many balls of light (magic barriers), which are very reasonably distributed and look beautiful.

There are entrances and exits in the five main areas of the city, and only these entrances and exits can enter the city, otherwise you have to break through the magical barrier, which has a defensive function in addition to water.

The other small areas can only be accessed through five areas, except for some special and hidden entrances and exits.

Ling Feng and Betty followed the merfolk into one of the entrances and exits of the adjacent area, and after opening a passage, Ling Feng rode the sea beast and continued inward, because the passage was still seawater.

After everyone has entered, the passage closes and the front exit is now open. There is a long ramp along the entire passageway, and the entrance is below the city level.

Burst......

Ling Feng broke through the water and found that it was a small circular lake connected by several waterways.

The waterway, which is the main transportation hub of the underwater city, because the sea tribe swims in the water much faster than walking on the ground, so there are many waterways distributed in the city, and some buildings are even directly connected to the waterway, giving Ling Feng a feeling of going to Venice.

Although the city is like a miracle, Ling Feng can't figure it out, obviously it's a sea clan, why do you want to separate the water like this, why don't you live directly in the water, so that even the magic barrier is saved, you must know that this is very mana-consuming. However, it seems that the Sea Clan does not use the magic core as a power, it is a crystal in the sea, a crystal that stores mana.

The crystal is stored in the magic elements of the water system, compared with the magic core, it is much worse than the magic core in terms of magic power, and the volume is also huge, so it cannot be used as a weapon like the magic core, but it is better than a large amount, which is equivalent to a mine, which can be used for people's livelihood or defense.

This kind of crystal mine was discovered by the sea tribe in the deep sea, and only two have been found so far, but its storage is very good, and it is still forming new crystals, so these two places alone can make the underwater city consume for tens of thousands of years.

As soon as Ling Feng heard about this crystal, he thought about how to use it, if it was used on some large magic guides and promoted, it could make the world change in essence. However, in the end, he gave up this idea, because these crystals are only found in the deep sea, and there is no one else who can mine them except the Sea Clan.

And the Sea Clan still wants to use these crystals to maintain their own cities, how can they give these crystals to people, so as not to destroy their own cities.

But a small amount should be fine, it's not bad to use these crystals to make some submarines and other things, hey, you can transform the Black Pearl to make it have the function of diving, just like this underwater city, which is separated by a magic barrier.

At that time, the Black Pearl will be able to have the function of diving, although it can also be separated from water now, but it can't last, and the consumption of the magic core is a bit large, so it can't be wasted.

But this crystal is different, take a volume the size of a human, you can keep the Black Pearl underwater for a month, and it also has the power system to supply energy. For Ling Feng, the magic power of any department of boredom can be used as motivation.

Hey, it's a pity, it would be nice if the Sea Clan didn't want this city, then there would be as many crystals as they wanted, uh, of course

Busy mining.

In any case, this time it is not in vain, at least you can know that there is still this kind of ore in the world, I don't know if there will be other crystal mines?

There won't be, and there will be just a little, and it won't become a mine like the crystal on the bottom of the sea.

Because this is a special crystal born from the sea, the conditions are very likely to form in other places, and it can be said that it is almost impossible, and these can already be said to be miracles of creation.

The Black Pearl became a "submarine", which seemed to be of no use at all, because she was already invincible on the water, even if it was an imperial navy, she couldn't do anything with him, and besides, other ships couldn't dive and wouldn't go into the water.

Therefore, the Black Pearl, without diving, can run rampant on the water, and Ling Feng does not need to hide underwater, because the ship itself has a camouflage system.

However, it doesn't hurt to have more than one function, maybe it has a special use. The world is impermanent, and no one knows what will happen to them in the future.

"Ling Feng, please follow me. After talking to the other merfolk for a while, Amanda spoke up to Ling Feng, interrupting Ling Feng's chaotic thoughts at the same time.

Amanda swam into one of the waterways, and the sea beast under Ling Feng's seat had already followed her, in fact, she had just let the sea beast follow her, and Ling Feng's words were just polite and useless, because Ling Feng only needed to stand on top of the sea beast.

In this way, Amanda swam in front, while Ling Feng stood on top of the sea beast and looked at the scenery on both sides, and the street lamps emitted a faint blue light, illuminating the entire city.

These lamps are obviously made of that kind of crystal, and what shines is the crystal itself, and the size of the lamp is different, because the size of the lamp is different, some are like the size of an ordinary bulb, and some are as big as Shibei, and some are even larger.

Uh, wait, glow, crystal......

"Betty, where are you going?" Ling Feng grabbed Betty who wanted to jump away from him, but fortunately reacted quickly, otherwise he would be in trouble.

"Go get the gems. Betty's eyes lit up as she looked at a crystal lamp that was bigger than her own.

I know! Ling Feng heard Betty's answer, and knew that his idea was right, this Betty saw these crystals like she wanted, this kind of glowing crystal was extremely tempting to her.

"These are other people's things, or are they important facilities (lighting is an important drop, of course), how can you take them. Stay quiet for now, and when I have the chance, I'll ask them for crystals. Ling Feng was powerless, unable to take Betty's tone for granted, and when he saw something glowing, he didn't think about anything else at all.

"Really?" Betty had already resisted the idea of getting the crystal lamp when she heard Ling Feng's words in front of her, and when she heard Ling Feng say that she wanted to ask for crystals from the Sea Clan, she looked at Ling Feng with glowing eyes.

"Of course it's true, I need this crystal too, and I'll definitely find a chance to get it. Ling Feng replied.

"When did you want to be so greedy for money, and you wanted to see things. Betty asked directly.

...... "Greedy for money, you're talking about yourself."

"I'm useful, the magic of these crystals is what I need. Also, I will make a deal with them and will not take their things for nothing. Got it, little money fan. Ling Feng smiled.

"Got it. I'm not a fan of small fortunes!" Betty retorted symbolically, and turned her head to stare at the crystal lamps, still wanting to put them in her own space.

Ling Feng looked at Betty for a moment, then shook his head, smiled, and continued to look at the scenery and buildings on both sides.

After turning into a waterway, Ling Feng found that there were more people in the waterway, mermaids, Naga, and the Yates riding sea beasts were traveling through the waterway, which should have been a busier waterway.

When everyone saw Amanda, they didn't react much, they just said hello, which shows that the Sea Clan's sense of class is very weak.

However, when they saw Ling Feng and Betty, they had a great reaction - shocked, there would be a human race here, which was something they would never have imagined.

So everyone forgot what they were going to do, and what they were doing now, and they all stopped to look at Ling Feng and the others.

Fortunately, the waterway is wide enough, otherwise it will cause traffic congestion!

Amanda continued to move forward with Ling Feng, walking through the sea tribe in a daze, and after turning a few waterways, it was time to go ashore, because it was necessary to cross the sea bridge in the middle to the royal area.

"Isn't it?!" Ling Feng watched as Amanda sat down on the stone steps, and what surprised him continued.

Amanda's fishtail began to emit a faint magical glow, and gradually the fishtail began to change......
