After the rain, the pool water became very turbid and had poor visibility. Zi Yang and Su Rui took advantage of the thrust of the underwater drone to slowly move downstream together.

When he reached the position where the steel cable was cut off, Su Rui pointed the cut off to Zi Yang. Under the light of the underwater drone, you could see the neat section of the steel cable.

Zi Yang worked on a construction site and knew that if it was a cutting technology such as an underwater welding gun, the cross-section of the steel cable should be relatively flat; if it was broken by external force, the part where the steel cable was broken should be broken into a twisted shape, but the section of the broken steel cable in front of him was different from the above two situations.

Su Rui pointed his thumb down and signaled to continue diving. After falling for a few meters, he finally saw the mysterious bottom of the pond.

There are some broken wood and dead branches washed in by rain at the bottom of the water, and in addition to this, there are mud, sand and rocks.

The water below is relatively turbid, and the searchlight of the drone can only illuminate a small area at the bottom of the cave. Jin Guoqiang operated the drone to cruise around the bottom of the cave to explore. It can be seen that the entire pool is like a straight up and down shaft, and the walls of the cave are full of hard limestone.

Zi Yang hugged the ground like a headless fly for a while, but found nothing. Su Rui was in the same situation as him - there was no magical object at the bottom of the cave. Not to mention the ancient tomb, there were no two tombs.

Zi Yang spread his hands and made a helpless gesture to Su Rui. This result was disappointing, and he didn't know what else he could do now.

To be on the safe side, Su Rui brought all the remaining air bottles this time. Zi Yang was not sure how long Su Rui could last at such a deep bottom, but he knew that the consumption of air at this depth would be large, and with the decompression factor, Su Rui could not stay for too long.

Zi Yang clenched his fist with his right hand and pointed his thumb up, indicating that Su Rui was about to float up.

Su Rui shook his head and made an OK gesture to him, indicating that he was in good condition.

Su Rui understood that the air bottle she carried could only maintain this deep dive. If they could not find anything in the pool, their expedition would basically end.

"Captain, have you noticed anything?" Su Rui said through the walkie-talkie.

"No, the bottom of the water seems to be closed." Jin Guoqiang said hesitantly. He had just controlled the underwater drone to circle the bottom of the hole, but did not find any dark holes or gaps.

"It is unlikely that there must be other holes around, so continue to look for them." Su Rui said.

Jin Guoqiang operated the drone to slowly circle the hole wall. Su Rui and Zi Yang used the light of the wetsuit to search the ground at the bottom to see if there were any channels such as holes or gaps for draining water.

After a while, Jin Guoqiang said helplessly: "I can't see any holes or gaps."

Su Rui said with some disappointment: "Strange, where did the accumulated water flow out?"

In order to save power, Jin Guoqiang stopped the drone's thruster. The drone was suspended in the water, and the searchlight light shone obliquely upwards.

Zi Yang suddenly touched Su Rui's arm and pointed it on it.

Su Rui followed Zi Yang's gesture and saw that in the light column of the searchlight, the mud and dust in the water seemed to be slowly flowing in one direction.

"The entrance of the cave is above! Captain, at nine o'clock, floating about ten meters above." Su Rui and Jin Guoqiang reported the location below.

"Received." Jin Guoqiang controlled the drone to advance upwards. Sure enough, on the cave wall more than ten meters above, there was a hole with a diameter of more than one meter wide. The water flow through the cave entrance was very slow, so at the beginning everyone did not find this passage hidden on the cave wall.

They were all focused on the bottom of the water just now, but they didn't expect that the waterway was more than ten meters above the bottom of the water. If the searchlight hadn't accidentally swept the above, they might have missed the discovery.

Jin Guoqiang operated the underwater drone to the entrance of the cave to watch. Following the light of the searchlight, he could see that the waterway reached horizontally, and the passage inside was curved and could not see the bottom at a glance.

"Go in and see the situation," Jin Guoqiang operated the drone and swam slowly. Su Rui and Zi Yang followed behind and entered the waterway one after another.

You can stand up straight in the wide area inside the waterway, and only one person can pass through the narrow area. The walls of the cave are covered with limestone washed out by water, which looks relatively smooth. After walking for more than twenty meters, there is still no sign of an end in front.

Su Rui reached out and touched Zi Yang, pointed to the barometer, and made a floating gesture - she only had the last spare air bottle left on her body, which was only enough for her to return and reduce pressure.

"Captain, the passage seems to be very long. My air bottle is almost used up and I can't hold on." Su Rui said regretfully.

"Okay, go back." Jin Guoqiang said, and the underwater drone stopped advancing forward.

Su Rui and Zi Yang turned around and swam back, while Jin Guoqiang controlled the drone to follow them.

"Hey, strange."

After swimming back for more than ten meters, Jin Guoqiang suddenly said on the walkie-talkie: "Su Rui, there seems to be a passage above the place you swam by just now."

Su Rui stopped, turned around and swam to the direction where the drone stopped, looking up. Sure enough, there was a vertical hole above, which was relatively narrow and could only allow one person to pass through.

Following the lights of the wetsuit, you can see the ripples above, and it seems that the water surface is a few meters away.

Su Rui looked at the barometer and calculated the gas consumption needed for the return trip in his mind. After hesitating for a moment, hesitated, hesitated and then jumped upstream.

After rising several meters, Su Rui's head was exposed to the water - this place turned out to be a closed underground cavity.

Su Rui turned off the oxygen valve, took off his mask, and tried to breathe - although the air was a little dirty, he could still breathe.

Zi Yang swam up, took off his mask, and asked in surprise: "Where is this place?"

"This should be a natural cave. Because the opening of the cave was sealed by water, an airbag formed." Su Rui judged.

The two wade slowly and walked in. The water became shallower and shallower, and soon they only reached their thighs. With the light on the wetsuit, it can be seen that this is a closed space the size of a basketball court.

"Su Rui, look there!" Zi Yang said in a low voice.

Behind a stone at the bottom of the cave, there seemed to be something black hidden.

Su Rui was also shocked. The two stood together at [31 Novel Network                                                      �

At this moment, the underwater drone controlled by Jin Guoqiang also floated up and slowly advanced to them.

"What's wrong?" Jin Guoqiang said through the walkie-talkie. The black object was on the shore, and the drone couldn't see it from the perspective of the drone.

Zi Yang raised the front of the underwater drone with his hand. The drone searchlight illuminated the stone. You can see that most of the "mysterious object" was hidden behind the huge rock, with only four black limbs exposed outside.

"What is this?" Jin Guoqiang couldn't help but exclaim on the walkie-talkie when he saw this mysterious object.

"Can it be a big spider?" Zi Yang thought of the terrifying creatures in science fiction movies, and his back felt cold. Could it be that this thing bit off the steel cable outside?

"Let's go back." Zi Yang's heart kept beating like a drum, and his legs began to tremble.

Fortunately, the mysterious object was lying there and did not intend to pounce on it.

"Don't be afraid, it should be two corpses." Su Rui whispered.

Zi Yang looked at her in horror. Is this the gentle and beautiful Su Rui he knew? Don’t you have to be afraid of two corpses? Why are you so calm?

"Zi Yang, don't shake your hands." Su Rui reminded him.

Zi Yang had no choice but to bite the bullet and lift the drone with both hands, pointing the searchlight light at the "mysterious object" behind the stone.

The two of them slowly moved forward a few steps. As they got closer, they could see that the few black things exposed outside the stone were indeed like human limbs.

If you move forward, you will have to get ashore. Zi Yang put down the heavy drone and the two of them approached carefully.

"Beware of the danger!" Jin Guoqiang said on the walkie-talkie.

Su Rui and Zi Yang slowly walked around the back of the stone. Sure enough, the one "hidden" behind the stone was not a mysterious creature, but two corpses wrapped in a diving suit. The ones exposed outside the stone were their legs.

Zi Yang used the light on the diving suit to shine on the two corpses, and there were ten thousand question marks in his mind. Who are they? Why did they appear here?

Su Rui walked forward a few more steps and suddenly exclaimed: "Nanmiyi!"

Zi Yang was shocked, and he also realized that the two corpses were wearing the two nanocloths they lost in the hospital.

Su Rui gently touched the corpse's arm with his hand. The tentacles were soft, as if the nanocloth had lost its function.

"What, what should I do?" Zi Yang looked at Su Rui and looked closer. The head of the corpse was covered with a mask. There was a layer of gray water vapor in the mask. It was impossible to see the face of the person inside. But the only thing that was certain was that the person inside was dead.

"Take them up first." Su Rui said in a deep voice.

When Zi Yang heard that he wanted to hold the body, his scalp was numb. But Su Rui seemed to have no intention of asking for his opinion. He put on his mask, picked up a body, and walked slowly into the water.

Zi Yang had no choice but to bite his teeth and pick up the remaining corpse in his waist. The "person" was wrapped in a nanocloth and hung softly in his hands, like a big boneless slug, not to mention how creepy it was.

After entering the water, the body did not weigh much under the influence of buoyancy. Su Rui was in front and Zi Yang was behind, and the two slowly swam out of the waterway. Jin Guoqiang operated the drone and followed from behind.

The two of them began to slowly float up, and after rising for a distance, Su Rui signaled to stay and relieve stress.

Two people were floating in the water, looking at each other, each holding a corpse in his hand. The situation was quite strange, and it was really a rare life experience.

After several pressure relief, the two corpses finally surfaced.

Su Rui took off her mask and looked at the air bottle's barometer. It was so dangerous that the gas had been completely used up. If she was one minute later, she might not be able to come back.

"Su Rui, are you okay?" Jin Guoqiang asked with concern when he saw Su Rui seemingly weak on the shore.

"It's okay!" Su Rui removed the used air bottle and slowly swam towards the shore.

Jin Guoqiang came over to help the two drag the bodies to the shore, and asked in shock, "What's going on?"

Su Rui sat on the ground and gasped for a while, kneeled beside a corpse with his knees, and gently pressed on the coat of Nanmei with his hands. After touching it a few times, he heard only a few slight clicks. The built-in safety lock in Nanmei had been opened.

Su Rui gently uncovered the mask of the nanocloth, revealing a pale and moist human face.

"I'll go!" Zi Yang was so scared that he took a few steps back. Jin Guoqiang leaned over and looked at the corpse carefully, muttering, "It seems that he has been dead for a long time."

"Yes, the sealing properties of the nanocloths are very good. Although the person has been dead for a long time, the body is preserved very well." Su Rui said while peeling the nanocloths off the body.

After a while, a wet corpse wearing underwear appeared in front of the three of them. The skin of the corpse was still very smooth and moist, but the muscles had turned into jelly.

Zi Yang couldn't help but frown and turned his head to the side. He had never seen such a dead person before. This scene was really disgusting.

I don't know how long the body was sealed in the nanocloth. As soon as it came into contact with the air, it immediately emitted a fishy smell.

"Who are these two people? How could they appear at the bottom of the water? Are they Professor Zhang's subordinates?" Zi Yang couldn't help but ask.

Jin Guoqiang remained silent and turned to check another body in a nanocloth. He saw that the equipment belt at the waist of "it" was still inserted with a curved cowhide scabbard, and the exposed wooden handle of the knife was not rotten.

Jin Guoqiang reached out and grabbed the handle of the knife, pulled out the blade with force. Everyone's eyes lit up. This turned out to be a dog-legged scimitar with a cold light.

Zi Yang looked at this dog-legged scimitar and suddenly felt familiar - I remember that James also had a dog-legged scimitar when he was exploring in Lop Nur with Alexander.

Jin Guoqiang turned around and walked to the stripped corpse, grabbed its left arm and raised it. He saw a blue tattoo on the inside of the arm of the corpse: two dog-legged scimitars were mounted together, with a hideous skeleton on it.

"Gurkha Cavalry!" Jin Guoqiang said with a frown.
