There is a waterfall on one side and a cliff on the other, stretching for thousands of miles, with no end in sight.

Coincidentally, when Shen Rui and Xiao Ba were washed down the waterfall by the turbulent sea, Xiao Ba subconsciously grabbed with his arms, and as a result, he grabbed a hard support, and when he climbed this support, he saw that it was a bridge, a bridge cast of yellow metal, with no fences on both sides, connecting the stone walls below the ocean and directly opposite.

If you look at the past from Shen Rui's point of view, the ocean of this underground world looks like an artificially made industrial product, the ocean itself is a reservoir made of metal, and the seawater overflows from the edge into the underground river, and the underground river is like a water circulation system, flowing into the distance and being re-poured back into the sea.

After seeing many miracles of the underground world, Shen Rui already had enough immunity, and he just cursed this miraculous marine project with a swear word, and then stopped caring about it.

What really attracted Shen Rui was the palace built in the middle of the rock on the other side of the bridge.

In terms of depth, this should be the mantle region, with a thickness of 2,900 kilometers of high-density rock formations, and the entire underground world, including man-made oceans that stretch for thousands of miles, are built on the mantle layer.

Suspended in the air, embedded in the mantle rocks, the palace is interconnected by this solitary bridge and the man-made underground world, a man-made marvel on one side and a feat of nature on the other, although the palace is also a man-made product, it is perfectly integrated with the naturally formed mantle, as if the builders had done it on purpose.

"This is the tomb of the god of the sea." Xue'er pulled Shen Rui tightly and said.

Shen Rui was stunned and puzzled: "How did you see it?" ”

"In addition to Atlanteans, I was taught a special language by my mother since I was a child, and you can see the intricate lines directly above the palace, which means the place where the god of the sea rests. ”

Shen Rui became interested in the tomb of the sea god, and asked Xiaoba to carry Xue'er to the main gate of the palace.

Cher looked at the inscription composed of intricate lines and read slowly: "My life storage system has finally been exhausted, and after many attempts and efforts, our dream of returning to our homeland has been shattered by greed, and I have decided to sleep here to protect the people who are loyal to me, they are the greatest achievement of my life." ”

"No intelligent or unintelligent life is allowed to disturb my peace after death except for my appointed heir, or else it will be met with my wrath."

"Explore Mechanical Engineer No. 101, Cha. Poseidon, the 35197762 year of the galactic calendar. ”

After Shen Rui listened to Xue'er's whispered reading, his eyes were about to fall to the ground!

As a lover of occultism, a senior member of the Discovery Forum, and a full member of the UFO and Alien Society in China, Shen Rui certainly knows what this passage means.

If Cher's translation is correct, Poseidon is not a god at all, but an alien who has been lost on Earth and wants to return home!

If Poseidon is an alien, then who are his comrades-in-arms? Who is preventing them from returning home?

With deep doubts, Shen Rui tried to push the gate that was ten meters high and completely made of alloy, and even Xiao Hachi came to help, with the powerful strength of Xiao Hachi's single arm and twenty tons, this gate to Poseidon's graveyard did not move at all.

"Brother Shen Rui, do you really want to go in and have a look?" Cher asked softly from the side.

Shen Rui smiled slightly, "Of course I think about it, I'm very curious." ”

Cher thought for a moment, "Maybe I can try." ”

"You?"

Shen Rui didn't believe it, he and Xiaoba couldn't open the door, how could the thin Xue'er do it?

But the facts shocked Shen Rui, only to see Xue'er walking over lightly, gently pushing on the metal gate with her slender snow-white hand.

Boom~

There was a sound of machinery turning behind the door, and the door seemed to have received some kind of secret signal and opened on its own!

"Cher, do you have special functions?" Shen Rui asked in surprise.

Xue'er lowered her head, blushed and whispered: "It is said that we should not disturb Lord Seagod's rest, but since Brother Shen Rui wants to go in, I can only do this, after all, you and I..."

"Cher, come in, it's so spectacular!" Shen Rui shouted in front.

Xue'er was shy, she just lowered her head and whispered, she didn't notice that Shen Rui beside her had rushed straight in, she wanted to say something that she had been embarrassed to say, Shen Rui's anxious appearance was too incomprehensible.

Thundered~

Xue'er had no choice but to follow Shen Rui and the bouncing Xiaoba, and also walked into the graveyard of the sea god, and the sound of machinery turning behind her was heard again, and without any warning, the heavy gate actually closed automatically.

……

Four hundred nautical miles away, Atlantis City, underground.

Zuo Tang took Ye Wuxian into the room next to the living room, this room was very large, like a small library, and the dense bookshelves were full of all kinds of books and stacks of dusty drawings.

For a scientific madman like Ye Wuxian, this is a precious treasure trove, and a large amount of precious and rare technical information dazzles Ye Wujian.

"Finally found it." Zuo Tang took out a book thicker than an Oxford dictionary from the end of the bookshelf and laboriously placed it on the table in the center of the small library.

"You see, this is a sketch of Atlantis drawn by Lord Poseidon himself." Zuo Tang said in a deep voice.

Ye Wuxian was stunned, just the outline is so thick, which shows how complex the overall design of Atlantis is.

Excitedly opened the album, Ye Wuxian looked carefully from the first page, time passed hour by hour, he didn't feel tired standing there, his eyes were sometimes shining, sometimes confused.

When the album turned to the last page, Ye Wuxian finally saw Poseidon's entire idea of Atlantis, and the doubts in his heart also reached the peak.

"According to the rough plan, Atlantis should be made up of three parts, a city in the shape of a ring, a tower leading to space, and a giant core control center of unimaginable complexity." Ye Wuxian wiped his eyes and said in shock.

Zuo Tang nodded and said: "Four parts to be exact, according to the long-standing legend of our engineers, Lord Poseidon did not come to this world alone, but also his three friends. ”

"They decided to build a flight system that we couldn't understand and go beyond the planet, so Lord Poseidon and his three friends agreed that they would each take on a part of building this complex system."

"Lord Poseidon is in charge of the mechanical part, that is, Atlantis City, and the other two adults make the Tower of Babel and the Hive Matrix respectively, you see, there is a square with a diameter of ten kilometers in the center of Atlantis City, which was originally used to install the Tower of Babel, and where the Poseidon Palace is located on this side of the city, there is a fountain square kilometer of 0.44 square kilometers, which is used to install the Hive Matrix."

Ye Wuxian was so excited that he couldn't get it enough, this design is simply the legendary space elevator!

The Tower of Babel, made of high-strength materials, catapults Atlantis into space, and the Hive Matrix is the intelligent central control system of the system!

Suddenly, Ye Wuxian thought of a question, and asked curiously: "You just said that Poseidon has three friends who are in charge of part of this system, and you just said two, and there is another person, what is he responsible for?" ”

"Oh." Zuo Tang merged the albums, only to see two circles drawn in gold on the back cover of the album, "Lord Poseidon's last friend has the highest combat effectiveness, but he doesn't know how to build, so he is responsible for finding the lost dragon eyes, according to legend, if there are no dragon eyes, even if the three major parts of this system are completed, it will not be able to start." ”

Ye Wuxian looked at the two golden circles carefully, with the pattern of the double dragon flying into the sky chasing the bright moon, isn't this the moon-chasing wall that Shen Rui has carried on his body all year round!?
