The dark and silent underwater environment is still an incomparably mysterious and vast world for human countries in the 21st century. Pen, fun, and www.biquge.info

The depths of the ocean are not as flat as people think, but like the land, there are tall and steep submarine mountains, hills, plains, basins, rifts and other complex and varied terrain.

If you look at the Earth from space, you can see that its surface is actually dominated by blue oceans, and the seven continents are only a small part, so it should be more appropriately called water balloon.

From the Atlantic Ocean to the Pacific Ocean, from the Indian Ocean to the Arctic Ocean, the total length of the Central Mountain System has exceeded 60,000 kilometers, which is one and a half times longer than the Earth's equator.

Many of the famous islands, such as Bermuda, Azores, and Asunción, are actually part of the water that extends out of the water from the undersea seamount.

The average depth of the Pacific Ocean is 4,026 meters, and there are as many as 30,000 underwater peaks more than a kilometer high below the vast sea level, of which less than 1% have been visited by human probes. And this situation will not change much in the foreseeable future.

Therefore, how many dusty secrets are hidden in the depths of these mountains at the bottom of the sea will not be known to human beings at all.

At the bottom of the sea, Zhao Xinglan's consciousness was attached to a king squid, and slowly approached the bottom of a high sea seamount. There are also a number of steep peaks in the surrounding area, which together enclose the submarine valley with a circumference of hundreds of hectares in the middle.

At this moment, this place has been carefully cleaned by a large group of battle splits, and all the sediment and sea creatures that inhabit it have basically disappeared, revealing a large area of gray-black hard rock.

On the surface of the rock mass of that mountain peak, a semicircular portal nearly 100 meters high instantly attracted all of Zhao Xinglan's attention.

It is a doorway cut directly out of the mountain, and it is equipped with a reddish-brown metal door frame and a giant door, with a large number of intricate and mysterious patterns, unknown giant animal patterns, and a large number of pictographic characters, which seems to be a systematic language.

“…… Have the meanings of these characters been translated?" After a brief moment of surprise, Zhao Xinglan quickly calmed down and asked this crucial question.

This thing obviously does not belong to the product of human civilization, at least not to the human civilization developed in this era, but I don't know how long it has been sleeping at the bottom of this deep sea.

"Of course, I've figured out everything that should be figured out! It does come from some vanished ancient civilization. The Mother replied.

Three days ago, a patrol detection split inadvertently passed by here, sensing the existence of the metal giant gate, to be precise, sensing that the metal giant door had the composition of the blue tide crystal mother, and after coming over to further investigate, he reported the situation to the mother emperor.

This news naturally attracted the attention of the mother emperor, so a large number of splits were mobilized to carry out a comprehensive survey and cleanup, and finally confirmed that this was a relic of an ancient civilization.

It has only one function, and that is a cemetery.

Moreover, in this submarine valley, there are a total of 197 ancient tomb ruins that have been counted, but unfortunately most of them have been damaged, and very few have remained intact.

If it weren't for the Mother Emperor, I don't know how long this ruin would have been sleeping at the bottom of the sea before it was rediscovered.

“…… According to my research and analysis, this gate, or this ancient tomb, you see, is the highest and most complete of them. The Mother said.

"Can you open it now?" Zhao Xinglan asked.

Since it is the highest standard, the identity of the deceased inside is definitely not simple, and it may be able to make some extraordinary discoveries.

Of course, the material of this gate is not simple, and it has survived such terrible sea pressure and continuous erosion for a long time, but it is still intact, which is by no means possible with ordinary alloy materials.

With the current ability of the Mother Emperor, it is impossible to forcibly open it, and it can only be done by tricks, such as cracking the code to open the door, if the door has a password.

"Absolutely, the way to open it is actually on this door, as long as you decipher the language of this civilization. The Mother replied.

Ten pike-shaped splits swam by, evenly lined up along the edge of the giant gate, and then a circle of pale yellow light emanated from their bodies, merging into one and slowly spreading outward.

Zhao Xinglan had already seen clearly that it was a layer of repulsion shielding force field, and under its action, the nearby seawater was squeezed away, and finally formed a hemispherical waterless space with a diameter of more than 200 meters.

"It's not easy. Zhao Xinglan said with a smile.

It can withstand the pressure of seawater at a depth of thousands of meters, even if this force field is supported by ten split heads, it is very amazing.

"It's okay, but it's a pity that this repulsive field can only last for a day at most, and then they will die due to the exhaustion of their vitality. The Mother said.

Zhao Xinglan nodded, the mother emperor at this stage can only do this level, only after it is promoted again, the abilities of the splits under his command will be improved and strengthened accordingly.

When the hemispherical waterless space stabilized, more than a dozen octopus-like splits entered one after another, and their bodies all flashed with a faint red glow, as if they could be immune to the effect of the repulsive force field, so that they could enter and exit without hindrance.

They climbed onto the surface of the giant door, and with the help of the suction cups on the tentacles, they crumbled on it for a while, and then they heard a dull roar, and a gap appeared in the middle of the semicircular door, and a faint golden light and smoke escaped from it.

As time passed, the gap in the gate gradually widened, slowly retreating to the sides, and finally retracted into the interior of the mountain.

A wide and deep corridor appeared in front of him, and fist-sized glowing dots could be clearly seen on the walls on both sides, and the soft golden rays illuminated the entire interior of the corridor.

The two splits took the lead in crawling in, quickly analyzing the air composition, magnetic field environment, pressure index, whether there were active viruses and bacteria, etc., until all the test results came out and confirmed that there was no substantial threat to the split, and the mother emperor allowed further exploration.

After entering a distance of more than 100 meters along the road, a second slightly smaller portal appeared, which opened smoothly and continued until the third gate was seen.

When the third door was also opened, Zhao Xinglan finally saw the scene behind the door, it was a huge mysterious hall, and looking at its area, I was afraid that the entire interior of the mountain had been hollowed out.

The hall is divided into two parts, the left and the right, in the center of the left side there is a wide high platform, on which are placed twelve sealed metal containers about three meters long, the surface of the container is full of intricate and exquisite patterns, which looks extremely gorgeous and noble.

On the right side of the hall is a huge saucer-shaped metal structure. (To be continued.) )
