Xu Xin didn’t know what was in this mine, but he didn’t want to know now.
Although each of these vines is not very strong, their number is unknown and he doesn't know how many there are, so he will not take the risk of entering this cave.
Xu Xin waited outside for dozens of seconds. The remaining two blood-marked vines slowly shrank back into the ground like monsters in the game that had lost their hatred value.
Suddenly, the vines emerged a little from the ground, with the tips of the vines pointing in his direction, as if looking at him, and then quickly shrank back into the ground, leaving only a few small holes.
Xu Xin breathed a sigh of relief and prepared to turn around and leave.
"Hmm!" Coco pushed his face and pointed her little paws at the holes on the ground left by the vines.
Xu Xin looked in the direction Coco pointed, and what he saw made his pupils shrink suddenly.
These holes and cracks are actually moving!
That’s right, the ground made up of stones and salt mines is wriggling as if it were flesh and blood!
Under Xu Xin's shocked gaze, the holes and cracks were actually gradually healing, and the crossbow arrow that had half of the vine inserted into the ground shook slightly, and fell down with the half vine, revealing the flat ground underneath.
In the end, the ground returned completely to its state before the vines appeared. Except for a little bit of gravel and salt slag and a few broken vines around, it was as if nothing had happened.
This ground actually has the ability to recover and can heal slowly!
Before he obtained the golden treasure chest, he also stepped out of the protected area. At that time, vines also emerged from the ground and attacked him. In the end, after the attack failed, they retracted into the ground.
That time, the cracked ground definitely did not heal automatically!
He couldn't help but take a small step back.
This situation is like a living creature that has been injured and its wound is healing automatically.
Xu Xin took a deep breath, and in order to verify his guess, he reloaded the crossbow, aimed at the wall of the salt mine cave and pulled the trigger.
"Swoosh-crack!" The crossbow arrow pierced into the stone wall of the mine, and stone chips flew everywhere.
"Huh..."
Suddenly, a breeze blew out from the depths of the mine, bringing with it a strange fragrance. Although the smell was relatively fresh, for some reason, Xu Xin, who had a mild pharyngitis, still vomited slightly, frowned, and covered his nose.
At the same time, the crossbow arrow inserted into the stone wall in the mine shook, as if it was pushed out of the cave wall, and then fell to the ground.
The cave wall, which was originally shot with a small hole by the crossbow arrow, has now returned to its original state.
He had used a pickaxe to knock on the cave walls before. They were all ordinary green-grade stones, but the stone walls did not return to their original state after being knocked.
He looked at the wall he had chiseled before, and finally withdrew his gaze in vain. He couldn't remember what shape he had chiseled the cave wall into before.
"… Really, is he alive?" Xu Xin's eyelids twitched, and he resisted the urge to turn around and run. "He wasn't like this before. Is it because he just woke up?"
The gusts of wind with a strange fragrance just now made his head a little dizzy, so he quickly took out an orange that could enhance his mental strength and a strawberry that could balance his emotions and ate them.
My mind cleared up instantly, and the panic I had felt before was alleviated a lot.
He ate another red berry, gained the ability of night vision, and looked into the depths of the pitch-black mine.
The salt mine cave is not deep. You can see the end of the cave at a glance, and it is only a few dozen meters away from the cave entrance.
What frightened Xu Xin was that there was a huge pit on the ground at the deepest part of the mine, which had never existed before.
Looking from the cave entrance, the pit is about two meters in diameter. There are some stones and salt mine debris around the pit. These debris are evenly distributed around, as if something had drilled out from the ground and then shook its body.
Looking inside from the hole, you can't see how deep the pit is.
He had come here twice to take salt from the mine and had checked the interior very carefully, even using an iron pickaxe to dig around. He was very sure that there had never been such a big pit inside the salt mine cave before.
Xu Xin checked the map again. As the vines retreated underground, there was no red light spot inside the salt mine.
The distance is dozens of meters, maybe we can let Mimi go in and take a look. It is very fast and will not be hurt by the monster that suddenly emerges from the ground.
"Mimi, can you go to that hole inside and see what's in it or how deep it is?" Xu Xin asked Mimi. If it didn't want to, he wouldn't force it, after all, it was very dangerous inside.
Mimi glanced at him, then took a few steps in the opposite direction of the cave entrance.
Well, it doesn't want to enter.
Just as Xu Xin was thinking this, Mimi, who was already far away from the cave entrance, suddenly took a running start and accelerated, and flashed into the mine like a flash of lightning!
It took it less than a second to reach the end of the mine, turned lightly, kicked the wall at the end of the mine with its hind legs, looked into the cave on the ground, and then quickly ejected with the help of the reaction force.
The whole process took only two seconds. Before Xu Xin could even react and just as he widened his eyes, Mimi had already landed more than ten meters away from the cave and was walking towards him.
Even the strange creatures underground didn't react until Mimi came out of the cave, and then a few vines broke out of the ground.
"Ah!" Coco cried out in surprise.
"… This is too fast!" Xu Xin was also shocked.
After drilling out of the ground, these vines turned several times, as if drawing a few question marks in the air, and looked at each other in confusion. It looked like a few people scratching their heads and asking each other: "Did something just pass by? Did you see it?"
Xu Xin had never seen Mimi move so fast before. Perhaps it was because the big pit inside the mine made it feel threatened, so it burst out at its fastest speed, almost becoming a shadow.
The hole was about 50 meters deep, and Mimi rushed to the edge of the hole in less than a second. If you count the speed, it's over 200! The upper limit of the highway on Earth is only 120. If Mimi drives on the highway at this speed, she will be deducted 12 points and her driver's license will be revoked.
This is ridiculous. This speed is really ridiculous.
However, such a rapid burst of speed was also a burden for Mimi. When it approached, Xu Xin could clearly hear that its breathing became much heavier than before.
Coco jumped off Xu Xin's shoulder and jumped onto Mimi. Mimi never objected to the touch between Coco and Silver King, which made Xu Xin a little jealous. He also always wanted to pet this big cat.
"Hmm?" "Meow."
Coco and Mimi started communicating.
Xu Xin asked: "How is it, is there anything in the pit?"
"Bing!"
Mimi didn't answer, but just lay down and licked its fur. Coco, on the other hand, started barking and kept waving its two little paws at Xu Xin, but Xu Xin really couldn't understand what it was gesturing.
Xu Xin asked Coco a lot of questions directly and asked it to answer by nodding or shaking its head.
After a lot of effort, he finally figured out the situation of the big pit that suddenly appeared in the mine.
The pit was indeed very deep, so deep that Mimi couldn't see the end. But there was something in the pit. The soil inside the pit was a faint red, and there was a very special fragrance in the hole.
Very deep inside the pit, there seemed to be something emitting a bright white light, so Mimi felt that the pit was very deep. Otherwise, if it was pitch black and there was no light in the pit itself, it would not be able to see inside the pit at all, and naturally it would not be able to come to the conclusion that the pit was very deep.
"Pale red soil..." Xu Xin's expression changed again and again.
Xu Xin had seen this kind of soil in one place.
The soil at the entrance to the underground world where the golden treasure chest is found, the soil at the entrance of the very long iron tunnel, is light red soil!
"Contaminated soil!" Xu Xin only felt his body was a little cold.
He recalled the faint strange fragrance he had just smelled. It was not a pleasant fragrance, but it was still a fragrance after all. It was not as foul as the red mist that gushed out from the entrance to the underground world, but...
It’s not the same flavor, but that doesn’t mean it’s not the same substance.
In fact, there is such a magical substance on the earth, indole.
Indole is one of the important components of the special aroma of flowers such as jasmine, white orchid, lotus, and magnolia. It is used as the key to making perfume and is even used in various foods, but it also exists in large quantities in feces.
It has a pleasant floral scent at very low concentrations, but has a deadly stench at very high concentrations.
And the strange fragrance that Xu Xin smells now probably has the same properties.
From the very beginning, this smell gave him an inexplicably familiar feeling. After learning that the soil at the entrance of the pit was light red, he was almost certain that this smell was the smell of the red mist in the passage diluted thousands of times.
The smell gave him the same feeling as the red mist before, making him feel a little dizzy. Although it tasted good, it still made him feel nauseous.
As for the bright white light deep in the pit, he had no idea. Maybe it was a treasure or a trap, but Xu Xin would not go in like a fool to check it out.
Combining this information, Xu Xin's eyes towards the mine changed.
This is probably the entrance to the second underground world!
And the mine at the entrance might even be alive! At least it can automatically recover from its "injuries"!
No, we have to find a way to block this salt mine!
But after thinking for a long time, Xu Xin couldn't think of any good way to block the mine, so he could only move a few large stones from the side of the mine and symbolically block the entrance.
Although this approach is basically equivalent to covering one's ears and stealing a bell, since he could even move the stone, it is possible that he could not push open the things that came out of the ground, but he was really uneasy about leaving the hole open like this.
This way at least the things inside can't come out silently.
Looking at the blocked hole, Xu Xin at least felt a little better.
