One weekend morning, Xia Xue was watering flowers at home when she suddenly heard the doorbell ring.

Xia Xue hurriedly opened the door and unexpectedly saw Jacques. He wears a brown leather jacket and a helmet on his head and a helmet in his hand.

Xia Xue let Jacques into the room and looked at him in surprise at his outfit, which was a little different from usual. This smart outfit shows Jacques's temperament as a military man.

Jacques said with a smile. Today's weather is warm, the sky is clear, and there is not even a hint of wind. Therefore, he wanted to take Xia Xue to see a mysterious cave that had been sealed. This cave is about 50 kilometers away from the town, Jacques wants to go out for a ride on a motorcycle, and asks Xia Xue if he would like to accompany him?

Xia Xue happened to be idle and had nothing to do, besides, she very much wanted to know more about the surrounding customs, so she readily agreed.

Seeing that Xia Xue did not refuse him, Jacques was as excited as a child. He said, Xia Xue, it's still hello. When I went to ask the principal to go with me, she said that she was going to stay at home and bask in the sun because she was going to run around the world on a motorcycle, which is something that only boys and girls do.

Xia Xue was amused by Jacques's words. Jacques, the headmaster is more calm, maybe she likes quiet parties, right? Otherwise, when we ask the principal to go to the park for a picnic someday, she might go.

Jacques shrugged helplessly and said, "Okay, next time arrange a silent date for the Headmaster."

Xia Xue put on her coat and followed Jacques out of the house to see a three-way off-road motorcycle standing up in front of her house.

Xia Xue said with a smile, sitting on this motorcycle, I will feel as if I have returned to my high school days. Jacques, you can also ride a three-way motorcycle, it's amazing!

Jacques got on his motorcycle disapprovingly and said, "What is this?" I've even driven tanks and armored vehicles, I can even drive airplanes, and you just saw me driving a motorcycle, and you praised me for being amazing. Hmph, you're underestimating me, aren't you?

Xia Xue looked at Jacques with an aggrieved look and said, I'm sorry, Jacques, I ignored what you did in the past. You're a hero, of course anything!

Jacques became happy, waited for Xia Xue to sit next to him, and then started the motorcycle and drove down the hillside.

Xia Xue was imagining the cave all the way, and she couldn't wait for it.

When we finally reached the end, I saw a group of people standing in what looked like a garbage dump, watching something together.

Jacques stopped the motorcycle, walked over to Xia Xue, and helped her step out of the motorcycle.

Xia Xue followed Jacques to the cave. Jacques, can you tell me about the cave? It must be full of magic, right?

Jacques nodded solemnly and said. In the 60s, a group of scientists accidentally discovered a mysterious cave while passing through here. The depth of this cave is more than 12 kilometers, which is by far the deepest cave in the world. Since its discovery in 1960, no one has reached the bottom of the cave.

This mysterious cave has attracted a large number of adventurers and scientists to try to explore its mysteries, but unfortunately they have failed. What is the concept of a depth of 12 km? Jacques asked Xia Xue seriously. Xia Xue shook her head and looked at Jacques with expectant eyes.

Have you ever heard of the deepest ocean trench in the world, the world-famous Mariana Trench, which is only 11,034 meters at its deepest point? Jacques took Xia Xue's hand and explained carefully to Xia Xue as he walked forward. They walked to the ruined place, where the crowd of onlookers had gradually dispersed.

Xia Xue saw that the ground was covered with scrap metal and concrete residues. Walking through the ruin-like rubble, a large metal disc is bolted to the ground. The disc that was fixed looked like a manhole cover.

Jacques pointed to the manhole cover and said to Xia Xue. If you think it's just a discarded manhole cover, you're wrong. It was a drilled, welded lid with the mysterious cave sealed underneath.

Over the years, a large number of professionals have come to this mysterious land. Almost every year, there will be people who come to explore the mystery, and they are buried in the cave for no apparent reason. No one is alive, no one is dead, no one knows what these victims have encountered in this unknown cave?

It is said that when an adventurer spent the night next to the cave, he once heard the sound of fighting similar to the galloping of thousands of horses coming from the cave, and the grief and terrifying wails of the wounded, which made people listen to the creepy.

Jacques gently patted Xia Xue on the shoulder, comforted her, and continued. Especially in the middle of the night when the rain was pouring down, the adventurers who set up tents by the cave for the night, and after the strange midnight, they saw soldiers in armor, stained with heavy blood, holding the long contradictory cards of ancient times, crawling out of the mouth of the supernatural cave, wandering in the garbage dump in despair.

When the sun rises at dawn, these ghostly visions will all disappear. Later, I heard from the old people who lived in the nearby village that this place was once an ancient battlefield in ancient times. Two pairs of soldiers and horses, in order to fight for the city, fought here for three days and three nights, blood flowed like a river, and the sound of killing shook the sky.

Xia Xue couldn't help but gasp, urging Jacques to hurry up and continue. And then, Jacques, what happened?

Jacques smiled and said. In the 70s of the 20th century, a Soviet scientist, with his team of explorers, came to this mysterious cave and began to drill to the bottom of the cave. They are full of intense curiosity about the other side of the solar system, eager to understand the unknown world beneath their feet.

In order to prevent accidents, this group of exploration teams has made a lot of thorough preparations. They carried a lot of professional equipment, each with a solid harness strapped to their waists, and set up makeshift camps at different nodes of the cave.

As they descended to a certain depth using a rope, they were amazed to find that the interior of the cave was rugged and winding, and there were also many branching caves of various shapes. Continuing to explore, in the unknown depths, I unexpectedly heard the sound of rushing water.

Therefore, several people used professional diving equipment to explore whether there is a special life at the bottom of this river. As the descent deepened, they were surprised to find that the inner walls of the cave were extremely dry in some places and very humid in other places. In the cracks in the walls, there are strange creatures that resemble centipedes.

These strange beings inspired the confidence of these explorers. They cautiously continued deeper into the cavern, with the endless darkness behind them. Although a professional searchlight is placed at the entrance of the cave, the seemingly strong and omnipotent light cannot pierce the endless darkness of the cave.

Listening to the sound of running water on the soles of their feet, the explorers kept descending to their depths. But until they were exhausted, they still did not reach the bottom of the river. The diving equipment on his back is getting heavier and heavier, but the imaginary river bottom is far away. As the light of the hole in their heads disappeared little by little, they were completely immersed in the darkness, and their consciousness was gradually on the verge of collapse.

Finally, through the faint light of the headlamp, they discovered that in a branching cave, there was a strangely shaped mountain rock. They climbed up curiously, taking in the shape of the stone.

This stone, like a huge palm stretched out upright, can accommodate two or three adults between the fingers. With admiration, they took turns standing between the mysterious fingers, taking pictures one by one, and then passing the pictures to their companions guarding the exit of the cave with the professional equipment they carried with them.

Have these adventurers finally detected the mysterious world at the bottom of the cave? No one knows what these people saw and what they encountered on their way deep into the cave. The men guarding the entrance of the cave never saw these companions come up again, and like the other explorers, they mysteriously disappeared into the bottomless cavern.

Over the next two decades, there were many explorers. Their passion for scientific research has made them not succumb to the threat of death.

In 1994, another group of scientists came to this mysterious cave. They boldly drilled into this cave full of spirits again and again. Although the depth of the drill side did not reach the depth they expected, the actual exploration depth has exceeded 12 kilometers.

Although it was still impossible to decipher the deepest cave in the world, the scientists became the holder of the deepest depth of drilling, breaking the world record for the depth of excavation. In addition, they obtained 2.7 billion-year-old rocks on the way to drill sideways, and also found microscopic fossils of 24 single-celled organisms at a distance of nearly 7 kilometers. The temperature of these stones, as high as 180 degrees Celsius, is difficult to give a definitive explanation using the current physical theory of the earth's crust.

Today, this mysterious cave has been firmly sealed. Many locals believe that there is some mysterious creature and power hidden at the bottom of the cave, and that humans should not bother it.

Jacques finally finished telling the legend of this cave, and Xia Xue's thoughts were deeply immersed, and her eyes were contemplative for a long time. Jacques, this cave is amazing, the secrets of the universe are truly endless. If we spend the night here tonight, will we also see those soldiers of ancient times coming out to wander around?

Jacques smiled and stroked Xia Xue's head, like an adult soothing a child with a strong thirst for knowledge. Perhaps, but your current physical condition is not suitable for an overnight stay. After you give birth to your baby, we can come here for the night, okay?

Xia Xue looked at Jacques with full eyes, her expression was still full of solemnity, and she nodded seriously. After a while, Xia Xue suddenly smiled and said. When we come here for the night, I'm going to bring dumplings in a thermos bucket. If we can communicate with those soldiers, I can invite them to taste the dumplings I made, do you think it's okay?

Jacques looked up at the blue sky and laughed. He gave Xia Xue a thumbs up, and said again and again, Xia Xue, your dumplings will be welcomed by the whole universe!

Xia Xue saw the playful look on Jacques's face, and angrily raised her hand to beat Jacques's chest, asking him what he meant? Jacques laughed and ducked backwards, laughing merrily.

At this moment, Xia Xue keenly felt that a beam of eyes was watching her not far away. She quietly turned around and looked in the direction of her gaze.

Xia Xue was shocked to find that there was a burly man with a full beard, staring at him with deep eyes. It was a typical American man with a camera in his hand. Seeing that Xia Xue had found him, he smiled at Xia Xue and turned to leave.

Xia Xue tugged at Jacques's sleeve with palpitations, and quickly left the ruins under the pretext of wanting to go somewhere else.
