Wait, there's something wrong with the sky - there is no blue sky and white clouds, and there is no sun, moon and stars, but the rocks of the underworld, and out of nowhere the faint light is projected? Maybe it's the cracks between the rocks that leak into the sky, or maybe it's the fluorescent material in the sea, like it's under a cloud all day long.

It's still a huge underground space, big enough to hold an ocean.

Qin Beiyang believes that there are secrets deep in the earth that have never been explored by humans. He and Jiuse rushed to the beach, washed off the sweat on their bodies with seawater, and tasted it lightly, and it was really bitter and salty seawater.

Unable to distinguish between east and west, he climbed a ridge along the coastline, and he saw a city crawling on the shore......

Incredibly, the city is made up of countless concentric circles with three pyramids in the center. The streets and buildings in each concentric circle lead diagonally into the sea. A 100-metre-high lighthouse was erected in the harbour and decorated with sculptures of three horse-drawn carriages. Qin Beiyang and Jiuse walked into the streets, empty and deserted, except for the gilded observatory, the palace of the sun god, the amphitheater and the arena, and the ubiquitous public baths. The Taurus sculpture in front of the pyramid writes incomprehensible symbolic words.

Atlantis.

The island of the Atlantic Ocean in ancient Greek legend was first seen in Plato's "Dialogues", and it is said that 10,000 years ago, the city of a million people sank to the bottom of the sea in the Great Flood - it turned out that Atlantis sank into the interior of the earth along with the sea.

Qin Beiyang walked to the beach and faced the mosaic mosaic with colorful murals - there was a man and woman hiding under a fallen tree, was that the wreckage of the World Tree? Men and women survived and multiplied in tree hollows. Land grows out of the sea, green and gurgling, and after the twilight of the gods, the world is reborn...... The mural points out the direction, and on the other side of the sea is the continent of hope.

The sea is boundless and the sky is the shore, and the mountain is the peak, and I am the peak - Qin Beiyang remembered Lin Zexu's couplets when he was a teenager.

How do you cross the sea?

Qin Beiyang found a dense forest, with abundant tropical fruits and a steady stream of hot spring hot water, probably because of the high temperature underground. He replenishes his energy, cutting down trees, peeling off their bark and twisting them into ropes, joining thick logs into rafts. He also collected plant fibers, worked day and night like a woman, woven them into strong textiles, and finally made them into huge sails.

The raft was completed - composed of twelve towering logs, with a mast several feet high erected in the middle, triangular white sails hung, plus several large oars and tail rudders, which was the means of transportation in Homer's epic times. He stockpiled a large amount of dried and fresh fruit for food and hundreds of coconuts for drinking water. There are fish in the sea, strange prehistoric animals, which are quite delicious to eat. What's more, there is wind at sea, and as long as there is enough space and there is convection of hot and cold air, there will be wind. As for the compass, it is the nine-colored tomb beast of the town, and the magnet in its head can discern the direction.

Everything was ready to stop, and Qin Beiyang set sail for the sea. He steered the sails on the mast, and the nine colors bit the oars and rocked the oars. The wind, although not strong, is enough to sail. There is no sunrise and sunset, no spring, summer, autumn and winter, he just needs to cross this sea, even if he dies in the belly of a fish.

He was an Odyssey, a warrior returning home from the Battle of Troy. He heard the mysterious song coming from the sea, the temptation of the banshee siren. He gaged his ears and those of the Nine Colors to avoid destruction. The deep sea is filled with glowing creatures, ancient sea beasts and sea monsters. Sometimes a large fish leaps high into the sea and skims over the sails of a raft, their broad fins spread out like the wings of an eagle. The big fish that is as flat as a manta ray is triangular, like a Caproni bomber, curiously flying around the Qin Beiyang several times, and then slapping its tail and diving into the sea, barely causing a splash......

After sailing on the sea for dozens of days, Qin Beiyang's hair grew longer and longer, and it was scattered behind her head like a woman. He didn't know where he was on the earth. Is it still the Arctic? But do you feel like you've traveled that far, to the underground of North America, or to the Mediterranean? Or even the North Pacific?

Nine colors guide him in the direction, the old rule, with the shortest distance straight to the opposite shore.

All seas have opposite shores, just as all lands lead to the sea.

He ate all the fruit and could only fish, and An Lushan's Tang knife became a fish knife for cutting sashimi. It doesn't rain in the subterranean sea, it doesn't evaporate, but he will die of thirst at sea, and he must cherish every coconut on the raft......

Finally, Qin Beiyang saw the other side, just like Columbus discovered the New World after seventy days of sailing. He saw a grim coast—a dark desert with no vegetation, not as beautiful as the Atlantean frescoes depict.

He and Jiuse jumped off the raft, and it was a dead and desolate place, far less than the scenery on the other side. Now that they're all here, don't you have to sail back again? He decided to go deep inland.

Walking, walking, walking, and at the end, a stone wall reached into the sky, like the high walls of a prison.

Qin Beiyang lamented that he was a prisoner of the underground world, but found a white skeleton lying in the rubble bushes.

Human bones.

He swooped down in front of the skeleton and found remnants of textiles, a rusted bronze dagger underground, shells and pottery and other ornaments, much like the ancient Greek artifacts in the Louvre Museum. On the stone next to the skeletal finger, there is a line of crooked writing, which seems to be ancient Greek letters-

Γν?θι σαυτ?ν

Although Qin Beiyang couldn't understand it, he kept the shape of this line of text firmly in mind.

Three thousand years ago, during the Western Zhou Dynasty in China, this ancient Greek also roamed the center of the earth – perhaps the Odyssey himself. When he went through hardships and dangers, crossed the sea in the center of the earth, but found that there was no way to go, died in despair, and left this line of writing, what did he want to say to future generations?

Qin Beiyang once again bowed down to this ancient Greek explorer.

Three thousand years from now, I will be a dry skeleton! Just when he was secretly sad, he found that there were many gaps in the surface of the stone wall, which kept the air circulating with the outside world.

Qin Beiyang still handed over the heavy responsibility to Jiuse and let it choose the best exit.

The young Qilin Town Tomb Beast transformed, explored the path with its snow-white antlers, spit out a glass fireball, and walked a long way along the stone wall, and finally selected a crack.

"I hope you're right." Before entering the crack, Qin Beiyang hugged Jiuse, "If you're wrong, I won't blame you." ”

The fissures are deep and boundless, like a labyrinth, full of pungent smells, sulfur or magma from an underground volcano?

He heard something.

Nine colors also heard it, like a raging storm, like a volcanic eruption, and more like the cry of thousands of people, who were crying and screaming, as if they were locked up in a secret room and burned, killed in a gas chamber, and perished in front of a firing squad......

It's the sound of hell.
