Shen Dong's heart was moved, indeed, for him, the mermaid clan and the shark clan are just a race dispute, for Shen Dong, he doesn't care, what he cares about is the two heavenly demons, let his children, gain power.

In this way, he can rest assured that his child will grow up, because he has never heard of the Yunling Dao body, and once he does not take care of it, Shen Dong is very worried that something will happen.

What he can do now is only to leave the shark clan and the merfolk clan behind, what he has to do is very simple, that is, find the heavenly demons, take them away, and catch two of them into the small world.

In the end, the two reached a cooperation, Shen Dong got the last key as he wished, and in an instant, the heart of the ocean was also instantly integrated into the key, the key, like a huge button, was held by Shen Dong in the palm of his hand in an instant.

And with the king of the shark clan leading the way, Shen Dong gradually came to the key area that the shark clan said.

It was very dark here, and if you didn't look closely, you couldn't even see anything clearly, but the next moment, the king of the shark clan walked directly to a candlestick, and in an instant, flames erupted on both sides, and a huge button appeared in front of Shen Dong.

"This is the lock of the key?"

"That's right, the reason why the mermaid clan is willing to hand it over to you is also because they fancy your strength, in fact, the mermaid clan chose many people before this, because after they didn't have the corpse of the heavenly demon, their strength also began to weaken, and some of them hoped for immortality, but they were not willing to go on like this, because if it goes on like this, it will only make their lives shorter and shorter, our shark clan is like this, the first generation of devouring the heavenly demon can live for two thousand years, and with the second generation, there are only one thousand years, the third generation, five hundred years, each generation, is decreasing sharply, And the merfolk are also very selfish, they try their best not to let other merfolk produce the next generation, to maintain their own bloodline, to survive, and must get the next generation to maintain.

So, they all want someone to sneak inside the shark clan and get the key.

In this way, they will be able to obtain two-thirds of the keys, and through the friendship of the sea god, they can obtain the test of the last key, which is the test you have just made.

Finally get the final key.

The three keys are combined to be able to open, they know that our shark clan cannot pass the test of the sea god, so they will have no fear, even if we get their key, they can summon the key back, but they don't know, you have obtained the heart of the ocean, originally you passed the test, let me also be a little worried, but I suddenly found that the connection between this area and the mermaid clan was broken, and I knew that the sea god gave you the key, and the merfolk completely lost the key.

Before you, there were 3,000 people who were tested, but without exception, all of them failed, some were caught by our shark clan, and some were directly destroyed by the shark clan who were tested, leaving not a single one.

Now that you have all the keys and the Heart of the Ocean is in it, the keys are yours and the doors can be opened.

In fact, this gate is not the door to open the Heavenly Demon World, maybe it is the gate to seal the Heavenly Demon World, these secrets even if I am a shark clan, I know very little, maybe the mermaid clan knows, but they didn't say, the situation is very complicated, I only know that behind this door, is the gate to the Heavenly Demon World, that is, the gate of the Sky City, after my shark clan comes out of the water, I can't be like the mermaid clan out of the water for a long time.

Otherwise, danger will occur. The other party said directly, Shen Dong also understood, his hand, lightly placed on the keychain, in an instant, the door trembled, for a long time, was directly broken free, in an instant, the door opened, the sky was hazy, like a strong wind swept countless dark clouds, completely shrouded in this vicinity.

Shen Dong looked around, his eyes were full of shock, and in the next moment, a thunderbolt fell on a sunny day, and the gate burst open in an instant, and a heavy twist made the gate open completely.

In an instant, what Shen Dong found was a stone gate, the stone gate, it seemed to be the original gate, but above the stone gate, was the water surface, and now there were countless mosses on it, covered with the entire stone gate, but there were no plants, Shen Dong gradually walked over, his hand to push the bluestone, in an instant, the stone pushed, the gate, was opened in an instant, Shen Dong only felt that his consciousness moved, and the next moment, it seemed to fly to a sky, a backward river, from below, slowly left into this cloud.

The next moment, the dark clouds dispersed, and Shen Dong found that the river was actually in the clouds, and within this cloud, there was a huge sky city.

The city seemed to be imprisoned by the formation, floating in the sky.

Shen Dong had also heard of this kind of suspension formation, and some major sects even liked to engage in some fairy realm secret realms like this to attract disciples.

Actually, this thing is of little use.

Seeing this scene now, Shen Dong didn't feel too excited, after all, whether it was the backflow of water, everything could be urged through the formation.

For a moment, Shen Dong only felt that not far away, there were countless phantoms that would fly, Shen Dong followed the stream, and soon, he saw a lot of creatures like elves, the bodies of these creatures were absolutely transparent, as if there was only one light and shadow, no color, like a ghost-like energy body.

And their ears were pointed, like tree elves, which made Shen Dong suspect several times that these were the elves.

And these elves also seemed to have discovered Shen Dong, and in an instant, a wing flew directly towards Shen Dong, and the next moment, it was a wind blade that hit Shen Dong.

Obviously, these elves had already considered Shen Dong to be the existence of the enemy.

Shen Dong secretly said that it was not good, and in an instant, he began to fight with these people.

Obviously, there are many of these elves, and their feathers are also transparent, everything is like ghosts, but they have substantial bodies, like transparent plastic, and the light can penetrate their bodies without any effect on them.

Shen Dong fought with these elves for a long time, as Mo Yun collided with the opponent's weapon, in an instant, the opponent's weapon was directly cut off, and instantly turned into a colored thing.

And this sword seems to be a spirit sword, just in their hands, it becomes transparent.

"There are invaders, they are very strong, and they are quick to come from." In an instant, a voice-like voice made Shen Dong secretly say that it was not good, this was to call someone.

Shen Dong hurriedly fought with the other party, but the other party dragged himself directly, and soon, a group of people flew over.

It's like an army, twice as strong as these people.

"Intruder, quickly arrest you, I can still let you go, otherwise, you will wait to be expelled by our Light Clan."
