"Professor Andrew, Zhou Cang, have you seen that thing before?" Obviously, Xiang Yu and the others also saw the black sedan chair under the water.

"We had a ghost ship in the waters of Laoye Temple yesterday. There was a sedan chair like this in the cabin, but it is not yet certain whether the specific shape is exactly the same." Andrew said.

"Let's go down and take a look?" I asked everyone for their opinions in a questioning tone.

"Let's go, but everyone must be careful." Lao Li continued my words.

Zhang Jisheng never spoke, but his actions were consistent with us, and he followed us to the point where the sedan chair was located and swam past.

However, what surprised us was that the closer we got, the more blurred the appearance of the sedan chair became, and gradually became a vast piece of black, as if there was a cloud of smoke in the bottom of the water.

There is no light under the water, but the darkness in this place can still be seen clearly when the light of the hernia lamp shines over. After all, water is transparent, but there is no light. But this ball of things is like it was originally black. The light of the hernia lamp is swallowed by it. It melts with the water, without any obvious edges. Before we know it, we are also in this ball of darkness.

Once a person enters absolute darkness, the bottom line of his psychological endurance is easily defeated. In addition, the terrifying sounds that appeared on my intercom for no reason just recently made me feel that there seemed to be many things beyond my ideology in this boundless darkness. So, although I still seem to be relatively calm on the surface, in fact, I was already scared to sweat all over my body.

"Professor, we seem to be wrapped in a ball of black paste, without even a basic sense of direction." Xiangyu said.

"I don't know what kind of substance these black things are, so even light can be swallowed. It's really unheard of." Zhang Jisheng finally spoke.

"What you think is a bit like if you haven't heard of it, dark matter that can swallow light?" Andrew said in a sarcastic tone.

Although everyone was wearing a breathing mask, I could still tell what the facial expression was like with bearded cheeks and fleshy faces. I couldn't help but feel resentful. If I hadn't wanted to use his power to attack the opponent who had been hiding in the dark, I really didn't want to contact this old man at all.

"You mean, a black hole?" There was obvious uncertainty in Zhang Jisheng's tone.

"Apart from that, can you have any other explanation?" Andrew said with a smile.

"But, professor, a black hole is a celestial body that exists in the universe, so how could it appear at the bottom of this Poyang Lake?" Xiang Yu's voice increased slightly, and she obviously did not accept Andrew's view.

"I didn't say it was a black hole, but it just means that these black things may have partial properties similar to black holes. For example, space-time distortion. Due to the small gravity on our earth, space-time distortion is minimal, and around the black hole, this anti-space-time deformation will become very large. In fact, since the time difference was discovered in the waters of Laoye Temple for the first time, I have been doubting that there may be special gravity under the waters of Laoye Temple, which can also explain the frequent occurrence of paranormal phenomena in this waters." Andrew explained slowly.

"So, the black sedan underwater just now is like the 'gravity lens' effect in the universe. It is this dark thing that absorbs the light emitted from the sedan at some point, and reaches our eyes through the refraction of gravity." Xiang Yu continued.

I am not particularly interested in astronomical knowledge, and coupled with the past ten years of abandoned life, I can only understand the conversation between Andrew and Wen Xiangyu, and I am basically confused about those specific concepts.

"Even if this black thing is really the black hole you are talking about, it's useless for us to stay here. The most important thing now is to find an outlet. The oxygen irrigation behind us is getting lighter little by little." I said.

"Brother Zhou, don't be discouraged. This thing will definitely not appear at the bottom of Poyang Lake for no reason. If it is really like Xiangyu and the others said, then this thing may be a key existence, and it may also be a breakthrough in this exploration of the Laoye Temple waters. So if we analyze it patiently, we will definitely find something." Lao Li's voice was still weak, but the tone of his voice could hear the hope in his heart.

"Old Li is right. Let's explore around and see if there is something overlooked." Zhang Jisheng said.

"Okay, let's stay for another half an hour. If you haven't found anything yet, go back to the water just now and make plans. What do you think?" Lao Li said.

Everyone hit it off and then looked around them.

In fact, in this black ball, I basically can't see anything clearly, and the teammates should be the same, so everyone is fumbled under the water with their hands.

Fortunately, there is also a walkie-talkie, so although we all couldn't see where each other was, we could still communicate through the walkie-talkie. The first ten minutes passed, and we had no gains except darkness.

Just as Andrew cheered us up, my hand suddenly touched a hard object and couldn't help but make a "huh" puzzle.

"Zhou Cang," Xiangyu immediately caught him, and she called me.

I couldn't help but sigh in my heart that this little clever ghost is really as fine as a needle. "I seem to have encountered something."

Almost at the same time I encountered the hard object, the black thing began to melt, so the hernia lamp I put on my head suddenly illuminated the object in front of me.

It is a circular structure made of animal bones, one ring is wrapped around one ring, and the inside is very deep and the bottom cannot be seen with the naked eye.

After the dark matter completely disappeared, we discovered that we had swam out of the pottery at some point, and now it was suspended in front of the ring structure. The distance between us was actually less than five meters.

"What is this? It looks a bit like a tunnel." Xiangyu swam to me, stopped, as if asking me.

"I don't know either. I should just see this thing ten seconds faster than you." I said with a wry smile.

"In the 1950s, archaeologists discovered a mysterious large circular structure in the Russian plain, surrounded by bones of the long-extinct ancient creature mammoth. After a period of research and detection, scientists speculated that this was a ruin used by humans to hold certain rituals or shelters 25,000 years ago. The mysterious large circular structure has a particularly similar appearance to the building in front of us." Andrew also swam up and said slowly after observing the circular structure for a long time.

"If you say this, then the building similar to a tunnel in front of us may be made of mammoth bones. But in this case, there is a problem. These bones should have existed here for more than 25,000 years. But at that time, not to mention Poyang Lake, it may not have been formed in the Yangtze River Basin. How could a tunnel made of mammoth skulls be built at the bottom of this lake?" Zhang Jisheng said.

"Yes, your analysis just now is particularly accurate, but as an archaeology professor, I found in Russia and Ukraine that more than seventy ruins of mammoth bones piled up into houses. The appearance of those buildings is so similar to the one we see in front of us, and it feels like the same style of buildings." Andrew said.

"We don't have time to conduct too much research in which era this building was built. What we have to do now is to decide whether to go in and see." Just when Andrew and Zhang Jisheng were still going to argue, Lao Li spoke at the right time.

"I also think there is no need to discuss the period of this building now, but to go in and see what is inside." Xiangyu said.

"Everyone, there is a problem now. We have now entered the depths of Poyang Lake. When I was preparing these equipment, I did not expect that we would go so far. So when I walked here, the guiding rope has been used up. If we enter the tunnel again, we have to talk about the guiding rope partition. In this way, we do not have the guidance of the guiding rope, and if we want to go out in the future, we will easily lose our direction and the risk factors will increase a lot." Lao Li said.

After Old Li finished speaking, everyone was silent for a moment. Finally, Andrew made his statement first. He took out the short sabre and blocked the guiding rope on his body without hesitation.

Then he laughed: "It can be more exciting to have a burning boat."

Seeing Andrew do this, I cut off the guide rope behind me.

Seeing this, Xiangyu and Zhang Jisheng also cut the guide rope.

At this time, Lao Li spoke: "Then next, let's put aside all grudges and interests, and work together to compete with the waters of the Laoye Temple."

Lao Li's two words greatly increased my morale. We all followed him into a tunnel made of mammoth bones.
