One Thousand Five Hundred and Eighty-Six Tiankeng?

Boom——
A muffled sound, smoke filled the air, and thick sand columns shot up into the sky and scattered like rain. Ye Han, who was far away, watched the explosion through the camera of Ningwuguan. When the sand column fell, there was an inconspicuous small hole at the explosion point, and the surrounding sand fell down layer by layer into the hole.
Xiao Yuan was very surprised: "Why is there no movement? Such a big hole, even if it is dull, it must be painful enough, right? Could it be that this thing is like a sloth, and it will take a week to know how to cry after a needle?"
"Who cares... Bridge, did you find it?" Ye Han asked anxiously.
"No positioning signal received!"
"What about other situations? Did you find anything?"
"No movement."
Ye Han sighed faintly: "I know, keep observing!"
"Did it not explode through?" Ouyang Ping said, "I'll go over and take a look!"
"No, it's too dangerous, let go of the drone." Ye Han said.
A mechanical spider was immediately released and quickly crawled to the edge of the explosion point. The camera turned down and everyone immediately saw a shallow pit more than two people deep.
Luo Qi was extremely surprised: "Ouyang, you are not right, you put so many explosives, and only made such a pit?"
"Go away, what do you know!" Ouyang Ping glared at him unhappily, "There is so much sand in the pit, do you know how deep it is?"
Luo Qi was stunned: "Oh, that's right, how could I forget about this!"
At this time, the mechanical spider had crawled into the pit, but when this thing was designed, it was not considered to drill sand. The soldier who controlled the mechanical spider tried several times, but failed to make the spider drill into the sand.
Ouyang Ping sighed: "I'd better go over, we have wasted enough time."
Ye Han hesitated for a moment, gritted his teeth and agreed: "Be careful!"
Ouyang nodded, jumped to the edge of the sand pit in a few steps, and looked into the pit. In addition to the sand, there was only the mechanical spider spinning around.
At this time, Ye Han and others also followed. Two soldiers fixed the safety rope on Ouyang Ping. Ouyang Ping jumped into the bottom of the pit with the engineer shovel, grabbed the mechanical spider and threw it aside, waved the iron shovel and dug frantically, throwing the sand outside the pit to fly high.
Several soldiers fixed the safety rope on themselves and wanted to go down to help, but were stopped by Ouyang Ping: "No, I can do it myself."
Ye Han persuaded: "Let's go together, it's faster this way."
Ouyang Ping still refused: "Really no, I don't know what's going on below. The armor is so heavy, what if it collapses?"
The explosion failed to blow through the plane, but the damage to the plane was not fake. God knows how much weight the remaining thickness can bear.
Ye Han thought so too, and could only give up the previous idea: "Then be careful!"
Ouyang Ping used the shovel quickly. Every time the engineer shovel fell, it could be deeply inserted into the sand, but when the iron shovel fell again, it actually chiseled something, and only half of the shovel surface was inserted into the sand. Even through the armor, you can feel a strong recoil.
Ouyang Ping's eyes lit up, and he quickly slowed down his movements. He dug out the floating sand in a few strokes, revealing the flat surface that had been broken and shattered in the explosion.
Ouyang Ping squatted at the bottom of the pit and observed carefully for a while, then looked up and said, "Look, this is not chitin, it looks a bit like a worm tree!"
"No, you are talking nonsense to me?" Xiao Yuan widened his eyes, "Can't an animal's mouth open so wide, and can it eat such a big beetle?"
"There are many plants that eat insects, do I need to say this?" Ouyang Ping argued.
"Okay, okay, are you two sick?" Ye Han interrupted the argument, "No matter what it is, blow it up first!"
Xiao Yuan stopped talking immediately, and Ouyang Ping also dug the sand with all his strength, and he reached the bottom of the pit in a few strokes.
There were still scorch marks left by the explosion at the bottom of the pit. Ouyang Ping re-arranged the explosives, and everyone quickly retreated.
There was another loud muffled sound, and the gushing sand rushed into the sky like a spring, and it was like a whale buried in the sand.
Before the sand fell, Lin Yi's voice exploded in Ye Han's ears: "Location signal, received the positioning signal!"
"Great!" Ye Han stood up excitedly,
"Let's go and take a look!"
He didn't know what was under the sand, but the two explosions didn't cause any trouble. It can be imagined that the thing must not be the kind of alien creature that is difficult to mess with.
Before reaching the explosion point, he saw the sand near the explosion point sliding into the pit. He took a few steps and immediately saw the sand outside the pit falling into the pit.
Ye Han adjusted the communication frequency and called tentatively: "Calling the scientific expedition team, calling the scientific expedition team, please reply if you receive it!"
There was silence in the communication, no movement.
Ye Han's heart sank, and he looked into the pit, but he could only see a hole with a diameter of about two meters and a bottomless depth.
Xiao Yuan took out a fluorescent stick, folded it twice, and threw it into the hole. The little inconspicuous light was swallowed up by the darkness in an instant. The cave was still dark and nothing could be seen.
He looked up at the sun and said in distress, "It's too bright!"
Everyone's eyes have adapted to the brightness of the sun, so they can't see the situation in the cave clearly. The same is true for the optical equipment on the armor. With the brightness of the fluorescent stick, let alone one, even a ton can't illuminate the bottom of the cave.
Ye Han turned around and shouted, "Where is the grenade launcher? Do you have any flares?"
"Yes!" A soldier raised his right hand high, rushed to the edge of the pit, pressed a flare into the chamber, and with a light "bang", the flare drilled into the dark hole at the bottom of the pit.
A little light bloomed in the darkness, but the space below was much wider than expected. The range that the flare could illuminate was very small. Ye Han stretched his neck, but he didn't see anything useful.
A few seconds later, the flare seemed to fall into the water, and the illumination range suddenly expanded a little, but it became flickering again, and the ripples could be seen vaguely.
At this time, a soldier volunteered: "Captain, I'll go down!"
"I'll go too!" Another soldier also stood up.
"Go, go, go, go!" Ye Han pushed back unhappily, "Where are the spiders? Put a few in!"
The soldiers suddenly realized and immediately put two mechanical spiders into the hole.
When the spider was just sent in, the lens had not yet adapted to the light in the hole, and nothing could be seen in the lens. It gradually recovered after a few seconds, and finally saw something useful.
Xiao Yuan couldn't help but exclaimed: "This is simply a sinkhole, okay?"
Others agreed deeply, but the spider hadn't reached the bottom yet. In addition to confirming that the space below was very large, other things were still unclear.
Due to an operational error, the lens of one of the spiders suddenly turned upwards and aimed at the hole above. The screen was immediately illuminated by the sunlight hanging from the hole, which turned gray.
Ye Han could fully imagine that if he changed the angle, he would definitely see a spectacular scene of a beam of sunlight falling from the sky, just like an angel descending from the sky in a movie, or other similar scenes.
