Seeing that Li Mu's figure flashed back again, Luo Zhengfan also hurriedly followed.

"Be careful underwater and don't run too fast!"

Luo Zhengfan is also helpless, and this Li Mu's temperament is also too anxious.

"Lao Luo, hurry up, there seems to be a cave in here!"

Just as Luo Zhengfan was chasing after him, Li Mu's slightly surprised voice suddenly sounded in his mind.

"You wait for me!"

Luo Zhengfan quickly sped up and quickly flashed away in the direction where Li Mu was.

But when he came to the entrance of the cave that Li Mu said, he found that Li Mu's figure had already disappeared.

"Li Mu!"

Luo Zhengfan didn't have time to think about it, he let out a loud cry and rushed in along the entrance of the cave.

"Hey, Lao Luo, why are you more anxious than me, I just went to the front and took a look!"

Suddenly, Li Mu's voice actually sounded behind Luo Zhengfan.

"Don't move!"

Luo Zhengfan, who had been swimming in the front, suddenly stopped his movements and waved his hand suddenly.

Li Mu didn't know what was going on, so he hurriedly braked and stopped.

Now the two of them have come to the bottom of this deep sea, the so-called cave is also a small cave in this submarine mountain range, this cave mouth looks only as wide and narrow as two people side by side, about half a person high, and the two of them are diving, so it is not difficult to enter this cave.

It's just that Luo Zhengfan suddenly shouted in front of him, and Li Mu hurriedly landed on his feet and stood in place half-cat. Then he saw Luo Zhengfan's white shadow, and he was cautiously walking towards the depths of the cave.

"What the hell was found inside?"

Li Mu didn't dare to shout loudly, but in his mind, he communicated with Luo Zhengfan.

"This cave doesn't look natural, it's been dug out by hand!"

Luo Zhengfan's voice then came.

"Artificial?"

Li Muxian cried out a little silently.

At the bottom of the sea, which is thousands of meters deep, there is not the slightest light, and it is precisely because of this that it is cold and dark all year round, and there are no plants or fish at all.

Thinking of this, Li Mu's heart suddenly felt a little excited.

"Shhhh

Luo Zhengfan waved his hand in front of him.

Li Mu hurriedly shut up, and then cautiously moved forward little by little.

The two of them were walking forward, this narrow passage gradually became wider, and the traces of those artificial excavation were becoming clearer and clearer, from the beginning you could see the traces of knife splitting, and then the passage gradually became smooth, and even under your feet, you could see the faint bluestone road hidden under the mud and sand.

The two of them walked out of a distance of about a few hundred meters, and in the end, the entire passage had completely turned into a huge passage two meters high and about four meters wide.

"What is this?"

At the end of the passage, Li Mu saw a gate.

The door, which at first glance was a record of countless years, was quietly looking at the two outsiders.

"Bluestone Gate. ”

Luo Zhengfan gently stretched out his hand, then put it behind the door, and then slowly closed his eyes.

"Bluestone Gate?"

Li Mu slowly raised his eyes, on the huge bluestone door, there were some rough carvings, and if you looked closely, it was nine dragons.

Although the lines are rough, you can tell that they are dragons when you look at the two dragon horns on the head and the four dragon claws.

"Lao Luo, what kind of secrets are hidden in the mountains in the deep sea?"

Li Mu saw that Na Luo Zhengfan was sticking to the Qingshi Gate people motionlessly, and couldn't help but convey the message with his mind.

"There's something alive in here?"

After a long while, Luo Zhengfan slowly opened his eyes, and then exclaimed.

"How is that possible?"

Li Mu was also a little surprised, not to mention that there was no sunlight under the sea, just this cold breath was enough to freeze all living beings, and Li Mu and Luo Zhengfan were still the supply of their own spiritual power, so they could barely maintain it.

"I sensed the breath of a living creature inside, not sure what it was, but definitely alive!"

Luo Zhengfan seemed to be trying his best to sense something, but in the end he was defeated, after all, the space behind this stone gate was too big, and he didn't sense it comprehensively at all.

"Can we go in and see!"

Li Mu's eyes gathered slightly, and after staring at the stone gate for a long time, he slowly exhaled a breath of turbidity.

"We can't get in, this stone gate can't be opened at all with the strength of you and me!"

Luo Zhengfan pondered for a long time, and finally sighed.

In fact, he is also very curious, after all, everyone has curiosity, there is an artificially dug cave on the bottom of the sea thousands of meters below, and behind the stone gate of this cave, he also feels the breath of the species, Luo Zhengfan of course wants to go in and have a look.

"Alas!"

Li Mu also sighed helplessly, it seems that he can only look at it, but he can't enter, this feeling is really uncomfortable.

Then, his gaze fell on the nine dragon eagles again, although the dragons were all doing the shape of flying, but their direction was all to one side, and the dragon heads of the nine dragons were all gathered in one place, suspected of the appearance of two dragons playing with pearls, but there was no 'pearl' for these dragons to grab.

Li Mu always felt that the carving on this stone seemed to be missing something!

What is it exactly?

Li Mu still couldn't figure it out for a while.

"Lao Luo, do you think there should be something in the position of this faucet?"

After saying that, Li Mu stretched out his hand and slapped it in the direction he was pointing.

Click!

Unexpectedly, Li Mu's hand just put it up, and then there was a slight cracking sound.

Then, the bluestone door under Li Mu's hand was like tofu dregs, and a large piece fell to the ground in an instant, and the shape was really similar to the shape of the bead.

Whew!

"Lao Luo, did you hear any sound?"

Li Mu stretched out his hand to pick up the gravel on the ground, looked at the suddenly extra groove on the door, and couldn't help but speak.

The sound sounded like the sound of breaking wind, but there was not a trace of wind in the cave.

It was like the sound of human breathing, but there wasn't a single living creature in the cave except for the two of them.

Gooo

Suddenly the water rolled under the feet of the two men.

"It's not good, Li Mu, let's go!"

Luo Zhengfan suddenly shouted, and then pulled Li Mu in the direction he came from and prepared to retreat.

But it was too late, and at the moment when he pulled Li Mu up, a chasm suddenly cracked under his feet, and before the two figures could make any movements, they instantly fell down and disappeared into the chasm.
