Sitting ten meters away from the cave entrance, Xu Xin held Coco and waited quietly for the red gas to dissipate.
It’s not that he didn’t want to go in, it’s just that the smell was simply unbearable for a human.
Moreover, Xu Xin was a little worried that the smell was poisonous. Although Xu Xin didn't have any other problems except being a little weak due to vomiting out his dinner, who knew whether inhaling too much would cause any serious effects on the body.
It’s better to be cautious.
Gradually, no more red gas floated out of the cave, and the surrounding red color also dissipated under the influence of the wind.
Xu Xin walked to the entrance of the cave and looked in. There was still a faint red gas floating in the cave, but it was already very faint, much better than when it just floated out.
After all, the cave is not ventilated, and it is unrealistic to let the gas completely diffuse away. This is already the best result. Xu Xin sighed and asked Keke: "Are you still going down with me?"
Coco's body stiffened, and after hesitating for a moment, she nodded her head and jumped onto Xu Xin's shoulder.
This little guy. Xu Xin touched its head, tied the clothes on his face, gritted his teeth, and entered the cave.
There was a faint red color floating in the passage inside the cave, but Xu Xin was surprised to find that the red gas did not fill the entire passage, but was only floating in the upper part of the cave.
He tried to bend down, and sure enough, although the air below still had a strange stench, it was already within his tolerable range.
"It seems that this strange gas is lighter than air. This makes it easy. The foul-smelling gas in the iron door should have dissipated!" Xu Xin bent over and moved forward in the cave, and quickly reached the location of the opened underground iron door.
Looking inside, there was a square iron passage that was only wide enough for one person to go up and down. There was an iron ladder fixed on the wall of the passage, and it was unknown how deep it went down.
The ladder was also covered in rust. Xu Xin felt a little scared looking at the passage, but he still stepped on the ladder and began to climb down.
The passage was very long, and Xu Xin climbed step by step. The only sounds in the passage that was like an underground well were his footsteps and the occasional whimpering sound of Coco on his shoulder.
The little guy was also a little scared, and he held on to the clothes on his shoulders tightly with his limbs, for fear of falling off accidentally.
"This passage is too long! I'm not really going underground!"
The passage was too long, and Xu Xin felt his arms trembling a little. But there was no other way, he had already climbed halfway, and he couldn't give up halfway and climb up again.
Continue to climb down.
He didn't know how long he climbed, but just when Xu Xin felt he was about to lose hold of the ladder, he finally entered a room.
After climbing down about four or five meters, Xu Xin had already stepped on the ground.
"Finally climbed up!" Xu Xin stood on the ground, kneading the muscles on his arms with his hands crossed, "Such a long iron passage must have consumed so much iron!"
While muttering to himself, Xu Xin turned around and began to look around. However, the first sight made his pupils shrink suddenly and he took a breath of cold air.
The whole room was empty. Three of the four walls were made of standard iron plates and there was not even a window. Only on one wall was there a door that looked very thick and solid. The door was round and a bit like the door of a safe.
The first thing he saw was a human-shaped skeleton in tattered clothes leaning against the wall.
“Someone has been here before!”
Xu Xin was a little shocked. Deep underground in this wilderness, there was an underground room that looked like a vault, but there was actually a skeleton in this room!
Who is he? Is he a survivor from the past? Or is he a native of this world
Xu Xin looked at his clothes carefully. Even though they were very tattered for some reason, he could still tell that they were standard wilderness survival outfits.
Walking forward, Xu Xin saw a dirty package placed next to the skeleton. The package was made of animal skin. No one knew how long it had been placed underground. Most of the skin of the package had fallen off, and it looked extremely shabby.
"Sorry to bother you, brother." Xu Xin muttered to himself and opened the package.
There was a musty smell in the animal skin package.
The things inside were quite mixed, so Xu Xin poured out everything in the package and began to count what was inside.
"A completely rusted and falling apart multi-purpose knife, an empty lighter, and a small flashlight. These are all tools from Earth! This person must have come out to survive in the wilderness. He has all these tools." Xu Xin muttered to himself, "But the question is, why would someone come to this world with tools from Earth?"
Coco jumped off his shoulders and dug into the stuff with her little paws.
There are even packages of empty-handed compressed biscuits in there.
He picked up the lighter and flashlight. Although the writing on them was a little blurred and the surface of the flashlight was even cracked, Xu Xin could still see the name and logo engraved on the surface of the product, all of which were words he could not understand.
He had some exposure to European writing, and this alphabet should be Greek.
He picked up the package of compressed biscuits again. Although he still couldn't understand the words on the package, he could still see the blurry production date on it, which was April 1980.
The shelf life of ordinary compressed biscuits is only about three years. If the compressed biscuits this person ate were not expired, it means that he has been dead for at least 40 years!
40 years ago, someone had already come into this world!
The moon in this world changed from a full moon to a new moon within one day, and the moon was much larger than the one in his original world. He knew that this was definitely not his original world. Even now that he saw the goods on Earth here, he still did not change his mind.
Xu Xin now feels a chill down his spine. What kind of secrets is hidden in this world
Could it be that someone had been sent to this world forty years ago? But how could he have brought things from there
Looking at the room again, the more Xu Xin looked, the more he felt that this place was like a prison.
But even in prison, there are toilets and beds, but here it is empty. Apart from the ragged skeleton in front of him, there is only an iron door that looks very heavy, and a passage above his head that can be opened, like a vent.
There was no diary or anything like that in the animal skin package for Xu Xin to refer to. He took another look at the skeleton's body and found nothing valuable except the tattered clothes, which made him a little disappointed.
Come to think of it, who would write a diary
"Ah!" Coco suddenly screamed, looking at the iron wall behind the skeleton.
"What's wrong?" Xu Xin followed Coco's gaze.
There seemed to be some words engraved on the iron wall behind the skeleton, but they were blocked by the skeleton, leaving only a few traces of the words.
Xu Xin moved the skeleton gently.
Unexpectedly, he just pushed it lightly to the side, and the skeleton fell to the side and fell to the ground, with its bones separated and shattered into pieces. Xu Xin jumped back in fright.
After the skull fell to the ground, it rolled around on the iron floor and returned to Xu Xin's sight. The front of the skull was facing Xu Xin, and the deep eye sockets seemed to be staring straight at him.
"Hiss!" Xu Xin took a breath of cold air.
He used to not believe in ghosts and gods, and was not afraid of skeletons or anything like that, but since he came to this world, his worldview has somewhat collapsed.
At least the science he knew could not explain why he woke up in this world, why plants grew so quickly, and why eating fruit could give him special abilities.
In this world, anything can happen, including this skeleton suddenly coming to life.
However, it did not come to life, but just looked like it was staring straight at Xu Xin.
It was very quiet in the iron house. Xu Xin suppressed the strange feeling in his heart and looked at the wall that no longer had any cover.
There was a string of words engraved on it, probably with a knife, and there were purple-black stains on the edges, which looked like dried blood.
But what made Xu Xin speechless was that the words carved on the wall were the same as the words on the flashlight and compressed biscuit packaging, all of which were strange letters.
Xu Xin had only learned English as a foreign language and had some exposure to Spanish. He could not understand other European languages, let alone Greek, the second most difficult language in the world.
"Hmm?" Coco tilted its little head and looked at the words on the wall. Not understanding anything, it withdrew its gaze and looked at the skull on the ground.
"This is too frustrating. I found the clue but I can't understand it." Xu Xin sighed and looked towards the heavy door.
Whether this underground exploration will yield any results depends entirely on what is behind that door.
