From the outside, Jingyue Lake feels very ordinary, like a very common lake.

But when Jiang Sinan dived under the lake, it was like a balance was broken, and Mirror Moon Lake began to permeate with an oppressive and mysterious atmosphere.

And as Jiang Sinan moved down, the more strange he felt the breath.

The surroundings were pitch black and extremely quiet, as if it was the mouth of a giant beast, exuding heart-palpitating fluctuations.

"How did this Mirror Moon Lake come to be?" Jiang Sinan couldn't help but have a question in his heart.

He felt goosebumps all over his body, and there was a chill that penetrated his heart.

"Don't worry about that, keep sneaking down until you reach the bottom of the lake!" the Dragon Emperor's voice also had a hint of solemnity.

Jiang Sinan took out a fist-sized night pearl, which was so dazzling that he could barely see the three feet around him.

He dived down, I don't know how long, until finally his feet touched the hard bottom of the lake when the pressure was so great that even he felt a little strained.

Suddenly, a faint light suddenly came from the front.

It was an eerie color, blue, flickering and dark, floating in the dark waters of the lake.

"Follow that light, I feel like I'm almost there!" the Dragon Emperor's voice became a little excited.

Jiang Sinan nodded, followed the blue light, and walked briskly forward, the bottom of the lake looked like it was all solid rocks, there was almost no sludge, and some aquatic plants were shaking in the cracks of the rocks.

"Eternity is gone...... Who will save me...... Help me......"

Suddenly, a hazy, mournful murmur sounded in Jiang Sinan's ears.

Jiang Sinan's heart was suddenly shocked, an unbelievable look flashed in his eyes, and he pricked up his ears to listen carefully, but found that the voice was getting farther and farther away, and it was already undetectable.

"Dragon Emperor, did you hear a strange sound?" Jiang Sinan asked softly.

"Voices?

The Dragon Emperor said a little strangely.

Jiang Sinan said the strange voice he had just heard, the Dragon Emperor was silent for a moment, and said lightly to Jiang Sinan: "Keep walking, when you reach the place where the blue light is, maybe everything will be clear!"

Jiang Sinan nodded, but still felt some vague voices, ringing intermittently in his ears.

He simply ignored it and continued walking forward.

The blue light was extremely strange, sometimes very close, sometimes far away, but all of them were firmly guiding in one direction.

Jiang Sinan had been walking for several hours, and he didn't know how far he had walked, and finally saw a passage appear in front of him, leading to the unknown depths of the earth.

"Huh, a lot of snakes!"

Jiang Sinan's eyes flashed, and he suddenly found that at the exit of the road, there were many water snakes that were more than a foot long, or even a foot long, with the thickness of their arms, coiling and wriggling there, and spitting snake hyacinths, and their eyes exuded a ghostly light.

There are thousands of water snakes, all of them are surrounded by the corridor, which looks hairy, and there seems to be something in the corridor that attracts these water snakes, but they dare not enter.

"Eternity is gone...... Who will save me...... Help me......"

Jiang Sinan found that the voice was clearer this time, as if it came from the corridor.

"Let's go inside!" the Dragon Emperor's voice trembled slightly.

Jiang Sinan nodded, slapped out a palm, the bright light flickered, and the unparalleled divine power swept in all directions, sweeping away all those water snakes, and then stepped into the corridor.

The road is not long, it looks like it has been deliberately chiseled out, and after walking a hundred feet, Jiang Sinan saw a golden enchantment.

Like ripples, flashing brilliant runes, it looks extremely mysterious, and there is a faint blue light throughout.

And those blue lights made Jiang Sinan feel a cold and bitter feeling, as if this golden enchantment was just to block the blue light from coming out.

"This ...... This is my dragon's secret technique of covering the sky?!What the hell is in it?"

The Dragon Emperor's eyes flashed, with a look of shock and excitement, staring at the golden runes and enchantments in front of him.

"Heaven-covering Secret Technique? What is that? How can this have anything to do with the Dragons?"

Jiang Sinan was a little puzzled.

The Dragon Emperor explained: "The Heaven Covering Secret Technique is one of the supreme secret techniques of my Dragon Clan, which can seal the heavens and seal all things, and can be said to be the most powerful sealing power, this golden enchantment is transformed by the Heaven Covering Secret Technique, but it seems that it has only been weakened to the current realm after countless years......

Jiang Sinan stared at the blue light in the golden enchantment, and said with a hint of solemnity in his voice: "I'm afraid that the ancestor of the dragon clan is sealing some evil existence, and those blue lights don't seem to be a good thing, do you still want to enter and see?"

"It may be the message left by the ancestor of the dragon clan, of course it depends on it! Don't worry, the things inside can't escape at all!"

The Dragon Emperor's eyes flashed, and he said with confidence.

He spat out a few syllables that sounded obscure, but there was a rumbling sound of concussions in the void.

The next moment, Jiang Sinan also had some mysterious symbols flashing on his body, and the Dragon Emperor took Jiang Sinan into a streamer and penetrated into the golden enchantment.

In the center of the cave, there is a circular five-colored altar, exuding a terrifying aura, and a faint blue light manifests out.

At the moment when Jiang Sinan appeared, the top of that altar flashed blue light in an instant, and a strange mist appeared, turning into a terrifying figure.

"Let me out...... You lowly ants...... Let me out...... Bloodbathed ......"

The rumbling sound sounded intermittently in the stone cave.

The figure was like a blue cloud, unable to see the face, fluttering, struggling, but unable to leave the altar.

The arcane runes around the altar flickered, and a faint golden light flickered, as if it was imprisoning something.

The entire cave changed in an instant, and countless blue lights emerged, like mist, and soon became a sea of blue.

And Jiang Sinan stood here, but he felt a cold in his heart, as if he was instantly stared at by some kind of existence.

"What the hell is this?"

Jiang Sinan's eyes froze, staring at the arrogant blue figure and asked.

The Dragon Emperor instantly flew out of the Hongmeng Creation Tower, manifested in the cave, and turned into a peerless powerhouse wearing a black dragon robe, wearing a flat sky crown, a majestic face, and standing up to the sky.

"I didn't expect to see this kind of existence here, the Heavenly Demon King from the Endless Void, and maybe even the Heavenly Demon Emperor!"

The Dragon Emperor's voice was filled with shock and disbelief.
