Rex, who had been waiting here, stretched out two fingers, first pointing to the top of his head, then to the depths of the water hole.
Sinbad made a clear gesture.
The former nodded, turned and walked towards the cave.
He raised his head and watched the air pipe suspended above the other's head. In addition to being familiar with the basic operation of diving suits, the three-day underwater walking was also a process of learning sign language and diving details. Among them, observing the state of the two trachea at any time is the most important thing, which is one of the reasons why two people are required to cooperate in salvage.
As a channel for maintaining breathing, the other end of the leather tube is connected to an air pump driven by a steam engine. No matter which tube is broken or blocked, the consequences can be disastrous. Therefore, special care must be taken when traversing difficult terrain and changing directions.
After seeing that there was no obstacle that could threaten the gas pipeline at the top of the cave, Sinbad also took a step and got into the water hole.
The surging sound in his ears suddenly subsided a lot, and he could clearly hear the hissing sound from the valve, as well as his heartbeat.
After about ten meters, the light became darker and darker. Looking at Rex's blurred back, he felt as if he was heading towards the abyss.
At this moment, the ground beneath his feet suddenly lifted upwards, turning from a flat road to a gentle slope.
In less than a quarter of an hour, Sinbad saw that the sea surface was no longer glittering with golden light, but was as quiet as night.
As Rex slowly surfaced, he couldn't help holding his breath, only to see a huge cave appearing in front of the two of them. Most of its outline was hidden in the darkness, and only a small area of the dome was illuminated by the light reflected by the sea water, revealing a faint blue with shimmering waves.
This water hole turned out to be a passage connecting the inside and the outside
He struggled ashore and was about to remove his helmet when Rex stopped him.
The Fiordlander took out a waterproof oil lamp from his pocket, lit the wick and observed it for a while before taking off his helmet, "Huh... It doesn't seem like this is a dead place."
"Is... the wind?" Simbady felt the slightest coolness across his cheeks after he lifted his hood.
"Well, there are probably other exits in the cave." Rex said excitedly, "In this way, the possibility of finding treasures here is a little bit higher. We are really lucky."
Sinbad was not very interested in finding good things. He was more concerned about the safety of the cave. Unexpectedly, the hollow terrain will form under the desert, which is beyond common sense. They will not dive deeper than 20 meters, and even if there are rock formations, it must not be too thick. How does the loose sand support a large cave? Will the dome collapse? These questions made him faintly uneasy.
After going out, it's better to report this discovery to the people of Greycastle. Sinbad thought to himself, although he was a little sorry for the Stranger Things Club, but this place is not far from Daqing Port, and he didn't want any accidents.
"The wind seems to be coming from that direction," Rex put his helmet on the edge of the pool and raised the oil lamp. "Let's go and have a look."
Sinbad had no choice but to pull out his waist knife and followed slowly.
However, as the exploration deepened, he only felt that the cave became more and more strange.
The rocks under my feet turned into soft soil in no time, and then clusters of green grass replaced the slippery moss, as if this was not the ground, but an oasis in Yinchuan.
"It's unbelievable that green leafy plants can grow here," Rex exclaimed. "I thought there would only be mushrooms and moss in the dark underground."
"Or... let's go back first," Sinbad said hesitantly, "I always feel this place"
Halfway through he was stunned.
"What do you think is going on here?" Rex didn't hear back for a long time, so he couldn't help but look back, "Huh? What are you looking at... a flower?"
Simbady only felt that his breathing was a little short. There was a beautiful little flower blooming at his feet. The petals were lavender, and the leaves were almost as thin as cicada wings, as if they would shatter with a slight squeeze. "This is... the flower of the angel..."
"Very rare?"
"No...it used to be everywhere." Sinbad said in a low voice, "Although I haven't seen it with my own eyes, in the legend about the messengers of the three gods, this flower is spread all over the coast, like a purple ribbon. It is also the most splendid sea of flowers in the extreme south."
"There is a sea of flowers in the desert?" Rex asked in surprise.
"It is said that this place was not a desert a long time ago, but was full of trees, grasslands and rivers like the north." He shook his head, "But with the departure of the three gods, the earth gradually became sandy and became what it is today. But What I want to say is not that this flower of the goddess has a very detailed description in the legend. Once it takes root, it cannot be moved. This is the reason why there is no flower sea in the oasis. It should have been extinct long ago... "
"It turns out that there is such a thing." The fjord man smacked his lips, "Perhaps it is precisely because the desertification did not affect the underground cavity that the flower of the angel that happened to be rooted here survived."
Is that really so... The strange feeling in Sinbad became stronger and stronger. For some reason, in this dim world, he felt like he was walking on an oasis.
The purple flowers around them gradually became denser, not like they had grown underground by chance.
Just when he was hesitating whether to move on, there was a sudden "click" under his feet.
Then a soft light bloomed from the soil, illuminating a radius of several meters.
"What's the situation?" Rex asked in surprise.
"I... I seem to have stepped on something," Simbady swallowed. "It seems like a plank."
"Could it be a trap?" He hurriedly leaned down and stroked the flowers and plants beside his feet with his hands, "This is ha, ha ha... ha ha ha..."
Hearing the laughter echoing in the cave, Sinbad felt his hair stand up, "What's so funny, hey, tell me what it is first!"
"Hahaha, it's a treasure! We found the treasure!" Rex said excitedly, "Look at it!"
When he brushed away all the soil, Sinbad was surprised to see that the light came from what was under his feet. It was a half-buried "stone tablet" with countless lines spreading on it, as dense as fingerprints. . The rays of light radiated from his feet as the center, setting off the monument like white jade. But although it looks hard, it feels like rotten wood, and it will sag a little with a little force, which is completely beyond the scope of common sense.
What is even more incredible is that once the foot is removed, the surface of the monument will gradually return to its original state, and the light will also dissipate, as if everything you just saw is an illusion.
"Is there a more magical treasure than this!" Rex repeatedly stepped on the "stone tablet" and said happily, "If you can dedicate this to the King of Greycastle, the title of honorary explorer will definitely be mine!"
"But... it's too big," Sinbad said, just from the small piece exposed, the whole "stone tablet" is probably bigger than the two of them combined. Moving out is never easy.
"The way is what people think. As long as you use your brains, you will definitely find a way. Or we can find another exit of the cave?" Rex suddenly stopped, "There seems to be another piece there."
Sinbad followed his gaze and took a few steps forward, and sure enough he stepped on the same "stone monument". With the light it emits, more gray-white outlines appear in the sea of flowers.
"This is also there, there is also that..." The two walked dozens of meters along the stone tablets, and at first they silently counted the number, but they quickly dismissed the idea.
In just a short distance, the flower of the gods has been covered by more and more stone tablets, no matter where they settled down, there will be light.
Until a huge wall stood in front of them.
"My God..." Rex gasped.
Simbady also felt a chill, and he slowly raised his head. Under the soft light, the outline of the stone wall was revealed little by little. They found that it was not a "wall", but a hill formed by numerous monuments stacked together.
Some of them are incomplete, some are broken into several pieces, but most of them are shaped like a square cuboid, and it is not an exaggeration to say that they are monuments. But when they were stacked together, it gave Sinbad a different feeling.
Buried "coffin".
