If it weren't for the spiritual sense, Yang Yiyun wouldn't have been able to discover this cave, because it was hidden in the reef, plus some aquatic plants to cover it, it couldn't be seen with the naked eye.

Only the spiritual sense can discover it, and the reef under the water is actually more appropriate to call it a mountain, very large.

The cave is like a portal.

The symbols carved on the side of the cave look very ancient and mysterious, and I don't know if they are ancient words.

Anyway, Yang Yiyun didn't know any of them.

But when he felt the breath of Xia Lu, he was overjoyed and hurriedly walked towards the reef.

After waving his palm to pick up the aquatic plants, Yang Yiyun opened a path into the dense aquatic plants and walked in, turned a corner, and a cave more than ten meters high appeared in front of him.

The strange thing is that when I used my spiritual sense to investigate before, there was an invisible force blocking the spiritual sense at the entrance of this cave, and the spiritual sense couldn't see it, and when I looked at it with the naked eye, maybe it was too deep inside, and I couldn't see what was inside at all, and it was completely pitch black.

It seems to be a cave full of unknowns, but with the breath left by Xia Lu, even Yang Yiyun can only get into the Longtan Tiger's Den.

The runes on the side of the cave door were full of ancient aura, and it was dizzying to look at, Yang Yiyun hurriedly withdrew his gaze, thinking that the spiritual sense could not view the cave, it should be related to these ancient symbols.

No matter what, Yang Yiyun had to go in and take a look, and walked into the cave with a gritted tooth.

As soon as he stepped into the cave, he immediately felt a chill coming, as if he had stepped into an ice cave.

When the entire cave was outside, it looked pitch black, but after entering, the spiritual sense still couldn't see, and this time Yang Yiyun seemed to have become a blind man.

However, he could feel Xia Lu's breath, and with this breath, he just walked down.

I don't know what kind of place this cave is, could it be Xia Lu's home?

Think it's impossible.

Because Xia Lu's home is this body of water after all, she was just a small fish at that time, but she didn't have the ability to open up such caves.

But everything is uncertain, she is a dragon clan, she has a true dragon bloodline, and she is also a noble bloodline in the demon clan, maybe this is the nest of the dragon fish clan.

Thinking in his heart, Yang Yiyun walked forward step by step.

Although there are mysterious and ancient symbols in the cave that can block the viewing of spiritual sense, it does not affect the entry of the water flow, and there is still water in the cave, but it does not affect Yang Yiyun, who has water avoidance skills.

At this time, Yang Yiyun remembered the night pearl of the Qiankun pot space, which was supposed to be handed over to Zhao Nan and sold with that batch of jewels last time, but after thinking about it, he still left.

Just in handy.

Take out a night pearl in your hand, and suddenly the surroundings light up, which can illuminate a range of three meters.

I raised it and looked at it, the cave was very flat, it didn't look like a natural formation, it was more like a cave passage that was carved out of force, and it stretched far away.

But it also made Yang Yiyun sigh that those who can dig out such caves must not be ordinary people, either cultivators with strong cultivation, or demon cultivators.

Holding the Night Pearl all the way away, after walking for half an hour, a faint halo appeared in Yang Yiyun's realization, and the color of his eyes was silver.

My heart moved, and I quickened my pace.

Yang Yiyun walked out of the cave passage for five minutes, saw the place of light, and his heart was filled with deep shock.

He didn't expect that at the end of the cave or after crossing the underwater reef mountain, there would be a magnificent temple about 100 zhang high when he walked out of the cave.

The entire temple shone with a silver light, and it was completely the color of crystal.

A word popped into his head - Crystal Dragon Palace!

When I was a child, whether it was listening to stories told by the older generation, or animations, etc., there was the appearance of the Crystal Dragon Palace.

This is the legendary dragon palace of the dragon family.

But the Dragon Palace has always existed in the East China Sea in Yang Yiyun's mind, who would have thought that there would be a crystal Dragon Palace in the waters of the Yangtze River?

Of course, it is not a real crystal building temple, and after walking in, I found that it is actually a relatively transparent light cyan jade, which is completely made of jade, but the height of a hundred zhang is very shocking.

Is this inhabited by a human being?

Definitely not.

Where do people live, live and be built back so tall?

Yang Yiyun thought that there was one word - demon.

Only with demon cultivation can there be a huge size.

What kind of demon is it?

Maybe there really are dragons?

With very curious doubts, Yang Yiyun stepped on the steps of the temple and arrived at the gate.

The thick and tall gate, with a half-meter wide analysis, is just enough to accommodate one person.

And Xia Lu's breath was in this Hongda palace, and Yang Yiyun didn't even think about it, so he entered through the half-meter-wide door crack.

After entering, the entire hall was bright, because the almost transparent jade was shining, illuminating the entire hall.

Already gone, Yang Yiyun first saw a palm-sized golden luminous body suspended in the center of the main hall, shining incomparably.

Below this luminous body is a high platform more than three meters high, with an area of more than ten meters wide, completely in the original shape, and on it are golden symbols, which are the same as those seen at the entrance of the cave before, covering the entire high platform.

What attracted Yang Yiyun a lot was the golden luminous body suspended on the high platform, and he didn't know what it was, anyway, the power emitted was very special.

This huge platform looks like an altar.

The whole hall looks very big from the outside, but it is also a space of more than 200 square meters, and there may be other halls.

However, Xia Lu's aura was still there, and it was strong, just above the altar.

Yang Yiyun jumped up and jumped onto the altar.

On the altar, there are also golden symbols on it, and there are complex lines that link the orderly symbols together.

On the altar, Yang Yiyun was shocked.

He saw dozens of fish scales and a puddle of blood.

There is no need to look for it, Xia Lu's breath is emanating from the fish scales and a pool of blood.

Yang Yiyun's heart jumped wildly, looked around and shouted: "Xia Lu......"

He shouted with his true qi, and there was no answer on his face several times, and some of his body lingered.

Fish scales and blood stains are easily associated with bad things.

There was nothing on the altar for the first time, the only change was that there were cracks on the altar, cracks like spider webs, and the altar seemed to have been cracked by some powerful force.

At this moment, Yang Yiyun's heart sank, although she followed Xia Lu's breath to find this place, it was just fish scales and blood stains on her body.

A bad premonition was magical in his heart, Yang Yiyun looked at it with red eyes, hoping that a miracle would appear, and in the next second, Xia Lu would come out of a corner of the hall, but no.

Incomparably depressed in his heart, Yang Yiyun looked up and saw the golden luminous body suspended above his head, at this time he got closer, and when he looked closely, he found that it was a super large scale armor, no different from fish scales, that is, it was the size of an ordinary person's palm, and compared with Xia Lu's fish scales, it was a piece of scale armor dozens of times larger.

What kind of monster beast's scale armor is so big?

At this time, Yang Yiyun's negative emotions were very serious in his mind, and he wanted to ask Wang Bad Side, he thought if Xia Lu was eaten by some kind of big demon?

Isn't it impossible, otherwise how can her fish scales and blood stains be explained, why can't there be no bones?

Moreover, the huge scale armor suspended is the scale armor of the demon beast, and it is not impossible for there to be any big demon.

With a horizontal heart, Yang Yiyun jumped up and thought about grabbing the suspended golden scale armor, he wanted to study what kind of demon scale armor it was, could it be that Xia Lu was devoured by these two huge scale armor demons?

When the palm of his hand grasped the huge scale armor, suddenly a terrifying, eardrum-piercing roar rang out.

"Whew~"

It's the sound of the dragon.

Immediately afterwards, Yang Yiyun's face turned pale, and the huge scale armor golden light was as dazzling as the sun, and a behemoth more than thirty meters long came out of the scale armor and was suspended in the air and Yang Yiyun looked down.

"It's ...... Dragons?"

Yang Yiyun's heart trembled, and he said in his heart.

The behemoth suspended in mid-air is more and more dragons, the Chinese people take the dragon as the Tengtu, and there are many paintings, films and television on the dragon, and what appears in front of them is the dragon.

A green dragon.
