In fact, everyone present must have guessed about this issue. This cold pool is on the sixth floor of King Chen's tomb, and no one has ever entered the ancient tomb below except for the first ancient tomb, if anyone has chiseled these ice blocks like this, it is undoubtedly the tomb builders who built the mausoleum in the first place.

But the more this happens, the more unbelievable it becomes. More than 1,000 years have passed since the construction of the mausoleum, but is it true that these ice cubes have been sleeping in the cold pool for more than 1,000 years without melting?

Although the temperature in this cave is very low, it is far from enough to keep the ice in, otherwise how dare we stay in the cave for so long in short-sleeved clothes, we are afraid that we will be frozen into popsicles long ago.

"Could it be true that there is a thousand-year-old ice that has never melted?" I asked.

"Naturally, there is a thousand-year-old ice, but it is in some extremely low places in the North and South Poles, as well as some snow-capped mountains at extremely high altitudes." Li Huiyan said.

I naturally know this, and Li Huiyan obviously didn't understand the meaning of my words.

"Xiao Yan, I didn't mean that, in fact, what I want to ask is whether there will be that kind of thousand-year-old ice that will never melt?" I said again.

"If the temperature around me is higher than freezing, there is probably no such thing as thousand-year-old ice, at least so far I haven't heard of it anywhere." Li Huiyan said.

"Well, it looks like I'm thinking too much." I nodded.

"Not necessarily, maybe there is a thousand years of ice in this world, but we have shallow knowledge and haven't seen it yet. If some ice cubes are infused with some special minerals, it is very likely that the melting point of the ice cubes will increase, and there may be a thousand-year-old ice that will not melt at normal temperatures. Li Huiyan said.

"So, it's really possible that the thousand-year-old ice is theoretical?" I said. If Li Huiyan's statement is true, then it can be explained why those ice cubes in the cold pool exist, maybe it is really because of some reason that we don't know, so that these ice cubes will not melt for thousands of years.

"This is just my guess, if the temperature of the pool is just below freezing, the ice will also remain unchanged for thousands of years." Li Huiyan said.

"It's unlikely, if the temperature of the pool water was below freezing, the pool should have froze completely." I said.

"Not necessarily." Li Huiyan shook her head, and then said: "If there are some special substances in the pool water, even if the temperature of the pool water is really below freezing, it may not freeze, just like the situation I just said." "Having said all this, it's really just our guess.

Why these thousand-year-old ice can exist for thousands of years without melting is impossible to figure out unless we can have more convincing evidence.

As these thousand-year-old ice continued to emerge from the water, the eyeless fish that were active in the cold pool just now had also quieted down, and the entire cold pool had once again returned to its previous tranquility.

But everyone knows very well that under this calm of Hantan, there are still terrifying dangers, and they dare not take it lightly at all.

After a while, the webs I had told the ghost-faced spider to weave were completely complete. This web is about two meters long and about one meter wide, so it can be easily held by hand.

"Now that the cobwebs have been weaved, let's do what we have just discussed. However, I still have to remind again and again that the eyeless fish in this cold pool are very ferocious, and no matter who you are, you must be careful. I glanced at the cobwebs on the ground, turned my head and said to Li Huiyan and the others.

Until now, I didn't know much about what the eyeless fish relied on to perceive the existence of the outside world. Eyeless fish have no eyes, so naturally it is impossible to see anything, and they rely either on smell or hearing.

In my opinion, the fact that an eyeless fish has no eyes is naturally the best news. No matter what the eyeless fish rely on to perceive the outside world, it is far less good than the eyes, whether it is smell or hearing, there are always times when things go wrong, and it is also very easy to be disturbed by other things.

"Don't worry, there won't be a problem. Although the eyeless fish is fierce, it will not be able to help itself when it leaves the water, as long as you keep an eye on its movements, it will be fine. Li Huiyan said.

Then, Qin Gong and I pulled the cobwebs apart, and Li Huiyan stood in front of the cobwebs. After doing this, the three of us slowly walked towards Hantan.

Although the temperature in the cave was extremely low at the moment, cold sweat was oozing from my palms, forehead and back when I approached the cold pool, which was enough to prove how nervous I was at the moment.

I glanced up at Li Huiyan and noticed that she was also a little nervous. Although what Li Huiyan said just now is not unreasonable, but the ferocity of the eyeless fish is a fact, if you are accidentally bitten, even if you don't die, you will be crippled for life.

After preparing for so long, I don't have much confidence in whether the webs of the ghost-faced spider can really catch the eyeless fish, so I can only secretly pray that I will not work in vain.

As we continued to get closer, the originally calm cold pool moved again. Because of the white mist on the surface of the cold pool, we can't see the situation inside the cold pool very clearly, and we can only rely on the sound from the cold pool to judge whether the eyeless fish really jumped off the water, which undoubtedly adds some tests to us.

When we walked to a meter away from Hantan, I saw that Li Huiyan was still walking forward, so I hurriedly reminded: "Xiaoyan, don't go any further, if you are too close to Hantan, you won't be able to react at that time." ”

"Well, here it is." Li Huiyan nodded, obviously understanding the danger in Hantan, but she didn't stubbornly move forward.

I could hear movement in the cold pool, but after a minute or so, there was no eyeless fish jumping out of the cold pool, which made me feel a little puzzled.

You must know that when the thousand-year-old turtle approached the cold pool just now, the eyeless fish in the cold pool jumped out in an instant to attack, and it was not just scurrying in the water like now.

"What's the matter, could it be that those eyeless fish in the cold pool are not aware of our existence?" After another minute, there was still no eyeless fish jumping out of the cold pool, and I said a little strangely.

"It's unlikely, the movement in the cold pool only came when we were close, and it would not have been possible if those eyeless fish hadn't sensed our presence." Li Huiyan shook her head and said.

"But since they have sensed our presence, why didn't those eyeless fish jump out of the water to attack people, could it be that they are not interested in people?" I said.

"Wait, there may be some other reason. If we wait another two minutes and there is no movement, we are choosing other ways to attract the attention of these eyeless fish. Li Huiyan said.

"Well, but if these eyeless fish really don't intend to attack people, what can we do. You can't really go to the edge of the cold pool, it's too dangerous. I said again.

"There will definitely be a way, so don't think about it so much yet, maybe these eyeless fish will move in a while." Li Huiyan said.

While we were talking, Dong Dan also held the stone in his hand and quietly walked to Li Huiyan's side.

"If the eyeless fish does jump out in a moment and you don't have time to react, I'll smash it with this rock." As if sensing the doubts in our hearts, Dong Shan smiled and said.

"Well, but you have to be careful, don't get bitten by an eyeless fish. Otherwise, no matter how thick your arm is, it is estimated that it will be bitten in two immediately. I said half-jokingly.

As soon as the words fell, the movement in the cold pool suddenly became louder. Before I could say anything, I saw an eyeless fish with a length of about a foot jumping off the water, opening its mouth and rushing straight to Li Huiyan, who was closest to Hantan.

The eyeless fish that suddenly jumped out of the water also startled Li Huiyan, but she quickly calmed down, and her body moved slightly sideways, and she easily dodged the attack of the eyeless fish.

But at this moment, something even more terrifying happened. The eyeless fish in mid-air did not give up after a blow missed, its body writhed quickly in mid-air, and then miraculously made a turn in mid-air, and pounced on Li Huiyan, who was already safe, again.

This sudden change really made Li Huiyan panic, even if we had been prepared for it before, we didn't expect such a thing to happen.

The eyeless fish turned in mid-air, which caught everyone off guard, and by the time Li Huiyan came back to her senses and wanted to run away again, it was already a little late.

"Squat down." At the same time, Dong Shan suddenly shouted. Hearing this, Li Huiyan quickly squatted down without saying a word.

That is, at the same time that Li Huiyan squatted down, the stone in Dong Dan's hand also flew out, and the stone drew an arc in the air, and it just smashed on the side of the eyeless fish's body impartially.

The huge force not only smashed the body of the eyeless fish out, but even the stones were completely shattered into several pieces, and the size of a fist fell directly on Li Huiyan's head.

After the eyeless fish landed, it kept struggling on the ground, but at the moment I didn't have the heart to care about it, and quickly walked up to Li Huiyan and cared.

"Don't worry, I'm fine, it was just an accident." Li Huiyan stood up, shook her head and said.

"I'll leave the task of luring the eyeless fish to me." Dong Shan said.

"Well, your reaction is a little faster than Xiao Yan, and it's indeed more suitable." I nodded. It was so thrilling that I don't want to repeat it again.

If it weren't for Dong's quick eyes, I'm afraid that Li Huiyan wouldn't be able to stand in front of us now.

About twenty minutes later, more than a dozen eyeless fish were caught, and all of them were unceremoniously dumped in a corner of the cave.

"Hey, there's something under this pool?" Li Huiyan said suddenly.
