From the underground river to the edge of the sea, it did exceed Lu Qing's expectations.

Even, after another flight, he actually came to the mouth of the sea.

In this area, a large hole was made at the edge of the continental shelf that extends eastward along the coastline of Tokai-gun, and the slope of the seabed suddenly increases.

From this large hole, there is a sea floor where it is difficult for sunlight to shine in.

Without rushing to continue exploring the depths of the seabed, Lu Qing checked at the entrance of the cave.

The concentration of spiritual energy here has reached the level of a fifth-order spiritual vein. However, at this entrance, he couldn't see anything out of the ordinary.

At first, he thought that there was something special about this entrance, which could make the sea water flowing in from the entrance change, become purer, and be endowed with a strong aura concentration.

However, it seems that what flows from here is not ordinary water, but naturally carries a strong aura.

After confirming this, he left the entrance and entered the bottom of the sea.

He sensed a peculiar ocean current, and the target flowed westward from the deeper depths of the ocean floor into the cavern.

Lu Qing curiously moved up and down left and right, and found that the surroundings were all very ordinary and ordinary seawater, and only the water of this ocean current carried a strong aura. It's like an aura passage at the bottom of the sea, and there are quite a few sea creatures living nearby.

It's a matter of course. In fact, when Lu Qing followed the underground Spirit River all the way, as the concentration of spiritual energy increased, he could find more aquatic creatures. These creatures, and even quite a few, have become spirit beasts under the nourishment of rich spiritual water.

However, in the stage of underground rivers, the space is too closed, and the aquatic life is generally not large. Otherwise, if the space is too small, it is indeed not easy to survive. And in the sea area at the exit, around the undersea aura channel, the size and strength of the aquatic creatures that survive here are suddenly much larger.

Huge sea fish, half-humanized, huge cetaceans inhabit here, and some distance further into the deep sea, you can even see some settlements of intelligent sea tribes, around which they have built special structures that can float in the sea, and settled here......

A gorgeous scene of the underwater world, to be honest, Lu Qing did not expect.

He had never explored the underwater world in such depth and detail as he did now, and he never imagined that the underwater world of the original cultivation world was so colorful.

The difference between the sea race and the land race is even greater than the difference between the demon race and the human race. Even in coastal areas, such as Tokai County, the connection with the undersea races is very rare.

The main thing is everyone's previous needs, and the difference is too big. What the Sea Race needs, the Land Race may not have at all, and vice versa. At the same time, the sea tribe is not suitable for the environment on land, and the human and demon tribes are also not suitable for the underwater environment. It is also natural that there is little contact between the two sides.

At the same time, Lu Qing also found that the civilization level of these undersea settlements is very low. Lu Qing specially spent more than half an hour staying next to a fish-man settlement to observe. They have very little communication with each other, their language is not developed, and their level of civilization is very low, and at most they only reach the point of producing a leader, and everyone listens to the leader.

Lu Qing was even suspicious, and even the communication between these undersea settlements was very small. They didn't have a currency, and even Lu Qing didn't see a general equivalent like a spirit stone, and there was not even such a thing as a transaction.

Of course, it is also possible that Lu Qing has not seen enough and has not observed for long enough.

But he really doesn't have much time to stay here and make scientific observations for a long time.

In fact, to be able to get here, he had already spent his karma several times to replenish his time out of body. Now the price of supplementing the time out of body is still within the range that he can accept, but it is actually quite expensive.

He didn't continue to observe, and continued to go deeper.

Soon, he felt the concentration of this aura current, which had risen to the sixth-order level.

This was to be expected, but after really having this feeling, Lu Qing was still inevitably surprised.

The aura level of the sixth-order spiritual veins ......

Turtle turtle, there are only three in the whole Yan country. Jade Smoke Mountain has been strengthened several times by Lu Qing with exchange items, but it has not reached this level, and it is still a fifth-order spiritual vein. The entire Yan country, as well as Yandu, Yunxiao Mountain in Wuzhou, and Luoyun Valley in Xingzhou, can have this level.

However, when he arrived here, Lu Qing also paid attention to a situation - he didn't see any undersea races nearby.

Lu Qing didn't think that this was their reluctance to come here.

The more concentrated the aura, the more attractive it will naturally be to any creature that needs aura for cultivation.

If it's not that you don't want to come, you may just dare not come.

At this point, Lu Qing also had a guess.

He continued to move on, and soon, what he saw, proved that his guess was indeed true.

There is a huge ocean city here.

At the same time, Lu Qing also felt that he had come to the source.

The end of this aura current is in the center of this ocean city.

Entering it, in terms of scale alone, this ocean city will not be smaller than Yandu.

Due to the particularity of the environment, this undersea city is a complete three-dimensional city. In the middle of the city, there will be things like roads in human cities. These roads are not only accessible in all directions, but also intersect into a network within a space, which looks very special from a distance and has a clear sense of design.

At the same time, on the edge of the city, Lu Qing also saw some resource points such as breeding farms. It is planned to look like a cube. In this water cube, there are some specific aquatic creatures cultivated, and there are even some underwater spiritual plants, which I don't know if they are used as food or medicinal herbs.

And in the interior of the city, the overall architecture also maintains a consistent style and is very distinctive.

A large number of underwater creatures wander around the city, just like humans wander around the city.

There will be a more obvious class division between them, roughly according to race. Shark people, whale people, and halflings that resemble mermaids have a significantly higher status, while those who are incompletely transformed into sea tribes have a significantly lower status.

Of course, there are some powerful individuals who can break through the limitations of this race.

While admiring the magnificent scenery of the underwater city, Lu Qing advanced towards the center of the city.

Halfway through, he also thought about it carefully, this undersea city whose name he didn't know yet, could the Yan Kingdom and the Lu family take advantage of it? Not to mention anything else, if the transaction channel could be opened, it would actually be very good.

Although there is a big difference between the two sides, after all, such a large volume is always profitable here.

At the same time, at this time, Lu Qing also left behind all the ideas he had thought about before that the undersea races were all uncivilized civilizations. Whoever sees such a scene and thinks like this is stupid to heaven.
