As Tang Juyi guessed, the central area of the bottom of the sea rock fissure, which stretches for an unknown length of time, is a cavern that has collapsed and extends underground, forming a horizontal structure similar to a tunnel.

The crater was large in diameter, and judging from the crumbling rocks around it, it was not just a simple crack, but more like some kind of violent collision that broke the rock at the bottom, and the extent of this repeated impact was so vast that it caused the formation of this sea rock fissure.

Normally, this can only be attributed to the unknown movement of the earth's crust, but after experiencing two hallucinations, Tang Juyi has already made a bold guess - the appearance of this sea rock crack is the so-called so-called submarine giant entrenched under the Death Curse Island.

"It's really getting more and more like 20,000 Leagues Under the Sea", it's just a super evolved version of a giant octopus...... At this size, even if you say it's Gatanjee, I believe it......"

After sighing in his heart, Tang Juyi controlled the submarine to sail into the underground pit and entered the underground passage.

The passage under the sea is full of traces of artificial excavation, its shape is square, and the rocks on the upper and lower sides have obvious carving marks, otherwise it would not be so smooth.

Not only that, but there are faint words and patterns on the rocks of the rock wall, although the lines are simple, but the amount of work is amazing enough, after all, this is not a work on land, but at an unknown depth under the sea.

The passage is so wide that even if the entire submarine enters it, it doesn't look crowded at all, and there is even room to spare. As the submarine progressed, the passage gradually extended upwards, eventually reaching a staircase.

It is a staircase for people to walk on, both in width and height, just enough distance for human steps, and two sculptures are placed on either side.

The upper part of the two sculptures has been destroyed except for the base, and only the broken stones can be seen, and it is impossible to tell what shape was carved before, but the "foot" organ can be vaguely distinguished, so it can be concluded that it should be a humanoid creature.

There are a total of ninety-nine steps of stairs in front of you, and the top position is a relatively narrow platform, where a stone-carved portal stands, and it seems that there should be a cave behind this portal, and it is very likely that it is the ancient civilization ruins recorded by the expedition team that has been sacrificed.

Since the space above the ladder was not suitable for exploration by submarines, Tang Juyi could only put on a diving suit and go to check it out for himself.

Fortunately, as the passage rises, the pressure of the sea water here is not very huge, and it is still at the level where the diving equipment can be loaded, otherwise as long as Tang Juyi dares to walk out of the submarine, he will be directly pressed into a meatloaf by the water pressure.

After controlling the submarine to stop and shutting down many systems, Tang Juyi put on the prepared diving equipment and entered the seawater directly from the connecting cabin.

After glancing at the indication of the pressure indicator and confirming that there would be no accidents, Tang Juyi stepped on the ground and walked towards the steps step by step.

Because the diving suit itself was relatively heavy, Tang Juyi's movement was extremely slow, and the movement of climbing the steps was also a little more difficult, and it took more than ten minutes to come to the stone gate.

The physical exertion was a bit serious, in order to prevent some sudden accidents after touching the stone gate, Tang Juyi did not rush to approach the stone gate, but stood in place and repaired for a while, and waited until most of his strength had recovered before continuing to come forward.

"Sure enough, it's something left over from human civilization."

Tang Juyi approached the stone gate and saw the carved patterns on the stone gate, which recorded a large number of ancient civilizations, and possibly their daily activities.

Most of the patterns on the stone gate are figures composed of simple lines, which look like people of ancient civilization, but the posture is like kneeling, as if to show surrender and prayer.

"Religious culture? Sacrifice to the gods? Or is it an expression of reverence for some powerful power? ”

Tang Juyi carefully observed through the glass of the diving helmet, followed the pattern all the way, and found that these pictures were all similar scenes of gathering and worship, but they did not depict what the object of worship was.

The research was fruitless, and Tang Juyi could only give up trying to understand the meaning behind these patterns, and instead thought about how to open the door.

Judging from the size and material of the stone gate, even if there are ten more Tang Juyi, it should not be able to push it, because its height is more than thirty meters, which can be called a gate for giants.

"How did they get in in the first place? Do you want to shout sesame seeds to open the door? ”

After wandering in front of the door for a while, Tang Juyi was also confused, because he didn't find any mechanism that could be pushed or pressed, only the huge stone door in front of him stood up.

Frowning and taking two steps back, Tang Juyi decided to simulate the exploration path of those members of the expedition team at the beginning:

"When they come to this stone gate, they should first record the patterns on the gate, and then they will turn their attention to the two sculptures......"

Turning his head to look at the broken statues on both sides of the stone gate, Tang Juyi walked over with slow steps.

After looking around the statue on the left, Tang Juyi still didn't find any clues, and only came to the conclusion that "this stone is a bit hard".

"Is it another sculpture?"

Tang Juyi, who did not believe in evil, came to the right side of the stone gate and circled around the second statue a few times, but still found nothing.

"Strange ......"

Tang Juyi felt a little incomprehensible, and couldn't help but look at the position of Shimen again:

"And how did they open the door? Could it be that someone in their team was born with divine power and directly pushed the door open? ”

Returning to the stone gate, Tang Juyi tried to pat the stone gate with his hand, but there was still no response.

"Knocking on the door doesn't work, and shouting underwater probably won't work, so there are only a few ways to try next......"

Taking a step back, Tang Juyi looked the stone gate up and down, and then made a move.

He knelt down facing the stone gate, imitating the carved pattern on the stone gate, like those people of ancient civilizations, kneeling in a very reverent posture in the direction of the gate, his hands were also flat on the ground, and at the same time he looked up in the direction of the stone gate, wanting to witness the miracle happening.

There was a long silence.

The stone gate did not open itself because of Tang Juyi's good attitude, but still stood quietly in front of him.

Tang Juyi stared at the pattern on the stone door with suspicion:

"Why, I gave my knee and didn't even let me in?"

The doubts in his heart gradually became stronger, and Tang Juyi also doubted his own thinking:

"Either I thought about it, or the posture wasn't sincere enough......"

Thinking of this, Tang Juyi no longer stared at the stone gate, but lowered his head like a true believer and knocked his head on the ground.

That is, when this action was completed, Tang Juyi finally had a harvest.

In front of him, on the platform under his feet, a large pattern was also engraved.
