The strange cold pool is like a cliff of broken souls, and the further down you go, the more spacious the interior becomes. It's just that this trend is not obvious, and Xiao Hei led two giant pythons and didn't find it. Zhang Chen also discovered this anomaly when he was about to dive more than 100 meters.

The soil around the pond is very hard, and the slope is curved, and it is impossible to detect it without careful observation. It's like an upside-down funnel, small in the mouth and big in the inside.

And the further down the pool water became, the colder it became, and wisps of cold air burst out from every drop of water, and the temperature in the cold pool had long exceeded below zero but did not freeze.

Zhang Chen only felt that a stream of cold qi was frantically pouring into his body, as if he was about to freeze himself into an ice mound, but his body was strong, his qi and blood were vigorous, his heart was beating strongly, and the blood circulation flow of his body was accelerating. The surging blood energy can be resisted, and there will be no danger for a while.

If you were an ordinary person, I'm afraid you would have become an ice sculpture a long time ago!

Even if it is on the edge of the cold pool, if ordinary people accidentally fall into the pool, even if they do not get frostbitten, they will catch a cold and flu, and even burn the root of the disease.

The cold air is too cold, or it is the ice attribute energy entering the body!

There was nothing unusual around the 100-meter cold pool, and no giant tortoise nest was found. Sure enough, not a single swimming white fish was found.

It's so deep, and it's a little weird.

Zhang Chen has system assistance and strong night vision. However, in the cold pool, you can only see the surrounding area for hundreds of meters, and the further down you go, the darker the light appears.

In his mind's eye, the terrain scanned by the system on the light screen was similar to what he saw. The bottom of the dark pool was blurred, as if there was something to hide.

As a special soldier, he held his breath very well, and he resisted the discomfort caused by the cold entering his body, and continued to dive in with a slight trembling body, his eyes scanning the surrounding walls, trying to find something abnormal.

The giant tortoise nest is one of the targets to seek!

This powerful mutant beast has the same intelligence as a child of three or five years old. I'm sure I'm going to collect something, and even if there's a treasure, I'm sure I'll be hiding.

However, his idea was good, but he didn't find the nest.

It is estimated that the giant tortoise is too high-level, and it lives in the cold pool all year round, and its body has some resistance. Able to go deep into cold pools and even build nests at the bottom.

This cold pool is like an invincible abyss.

Zhang Chen tried his best, and he could only dive more than 200 meters with his own ability. It's not that you can't hold your breath, and it's not that your physical exertion is too great. But the cold was too terrifying, pouring into the body through the biting pool of water.

His second-order evolutionary physical strength, qi and blood energy were gradually unable to resist. The body is becoming more and more numb, stiff, and even the blood flow in the body slows down.

This is still his physical strength far beyond that of ordinary evolutionaries, with many passive skill blessings, in other words, ordinary second-order evolutionaries can't dive into such depths at all.

Even if Zhang Chen gritted his teeth and persisted, his limbs were stiff, and the speed of flowing in the water was getting slower and slower, and it was estimated that if he continued like this, he would become an ice sculpture. Only the system's natural enchantment activates the terrifying cold.

It was as if an invisible energy shield appeared around him, and he felt that the whole world had become a better place, and he took a big breath of fresh air while not continuing to go deeper. Take Evolutionary Energy quickly. I ate a few handfuls of cooked amethyst rice, and moved my hands and feet in the water to do high-intensity exercises.

Waiting for the body to recover quickly, there were still no white fish in the waters more than two hundred meters deep. Keep this distance and still can't see the bottom of the cold pool!

Zhang Chen waited until his condition returned to his best before continuing to dive. With a natural barrier to keep out the cold, the pool water is not as cold as it gets. Swing your feet together like a mermaid in the water and rush to the bottom.

Half an hour later!

"It's been so long, I don't know how my brother is?" On the edge of the cold pool, Zhang Shan looked anxiously at the pool. Seeing that Zhang Chen hadn't broken through the water for a long time, he couldn't help but be full of anxiety.

"Shanshan, don't rush." Wang Hu said as he swam back and forth by the pond: "The boss is so powerful, it is normal for a soldier to hold his breath for a long time. Besides, as an ability evolutionary, he definitely has other special abilities. ”

"That is, we have to believe the boss, besides, it's too deep below, and we can't go down." Li Niu poked his head out of the water and said tremblingly.

Even if the two of them were second-order evolutionaries and were covered with tendons and flesh, they still felt cold and piercing in the cold pool, and the more they went down, the more numb their hands and feet became. In addition, he could not leave his post without permission, so he could only swim back and forth on the edge of the cold pool.

Even this makes them messy and shivering in the wind!

And it was with the comfort of the brothers that Zhang Shan thought about his brother's strength, so he was not so anxious. His eyes were fixed on Hantan.

"Fatty, if you want to become a strengthener, hurry down and take a soak." Wang Hu was doing high-intensity exercise while shouting to Jiang Ge on the shore.

"We have a clear feeling that the second leader's promotion on the second day is probably related to this." Li Niu used his hands and feet at the same time, and stretched out his hand to Jiang Fatman: "If you want to become a strengthener as soon as possible, come down and soak it to shorten the time." ”

"I'm afraid of the cold, look at the ...... of you two" Jiang Ge was eager to try, but when he saw the two brothers trembling and trembling, he retreated.

"Look at your worthless look!" Wang Hu was really defeated by this fat man. said that he was desperate to become stronger, but he retreated because he was afraid of the cold.

"I wonder if the boss can catch that kind of white fish?" Jiang Ge's eyes rolled, and he didn't want the two strong men to attack verbally, so he immediately changed the topic.

The dead fat man is really a chicken thief, and this topic immediately attracted everyone's attention.

"Needless to say, the boss must have a way." Li Niu's face was full of course.

"I just don't know what the white fish do?" The fat man Jiang salivated and smiled: "It would be good if it was cooked into a delicacy, dissolving poison, and enhancing physical fitness." ”

"Dead fatty, can you make a little difference!?" Everyone rolled their eyes in disdain. Jiang Fatzi's three sentences are inseparable from the essence, except that eating is eating.

"What kind of eyes are you looking at? Hantan White Fish, there must be a special effect, you say, Shanshan? Jiang Fat rolled his eyes and pulled foreign aid.

"It's definitely extraordinary, and the two giant apes are trying their best to capture them, which can be seen." Zhang Shan's anxious mood was put down, and she nodded thoughtfully.

"Often this kind of natural treasure is guarded by strange beasts, just like that giant tortoise." Jiang Ge changed his previous stupidity and became quite assertive.

Beasts are much sharper in their intuition than in humans, and they certainly look extraordinary, an instinct of living beings, and an innate talent.

"I can't wait, I hope the boss will succeed." Wang Hu's eyes were hot, and he shivered again: "This cold pool is strange, and the deeper you go, the colder it gets. Abnormality is a demon, I don't know what's down there? ”

"Based on the fat man's calculations, this is a big opportunity, maybe there will be that kind of polar cold iron, 10,000-year-old Xuanbing, right?" Jiang Ge pretended to understand very well. Actually, I don't know where the names of the various treasures came from.

"Damn, fat man, you've read too many fantasy novels!"

"That's not necessarily, we're evolving, and it's not hard to guarantee that the ancients wouldn't be like this."

"Yes, it's possible that the fat man said, and no one can tell what's weird down there."

"It's weird here, isn't it the ancient battlefield left by those powerful creatures in the past?"

"Ancient battlefields? If only there was an artifact underneath. ”

"Artifacts are not enough, even if it's a little broken treasure."

……

On the edge of Hantan, Jiang Fat Man opened a fantasy head, and a few people were talking about it. All kinds of strange treasures were mentioned and discussed. Waiting expectantly for Zhang Chen to break out of the water and see what was there.

And they don't know how deep this cold pool is, how deadly the cold air is!

Zhang Chen also didn't know that he was able to sneak in thanks to the protection of the natural enchantment. As for how deep it is, I only know that it is definitely more amazing than the Broken Soul Cliff.

In an area of four or five hundred meters of water, large clusters of white fish were found. The big one is about a foot long, and the small one is only the size of a palm, or even smaller. There are many of them, and there are many of them with a golden stripe on their backs.

This white fish looks like a white stripe, but its body is scaleless, crystal clear, and shimmers like a fluorescent. It is estimated that it lives in the depths of the cold pool all year round, is not affected by water pressure, and swims very fast, so it is difficult to catch it with bare hands!

However, Zhang Chen had already prepared, and his astringent breath was like a fish swimming close to the fish, using the prepared large net bag to catch it quickly.

The fish is very alert, but it can't detect him.

Naturally, it was difficult to escape, and it was easy to be caught by the net, and when he touched the white fish with his hand, the identification technique attached to the system fed back the information.

[Ice Spirit Fish, bred in extremely cold places, improve physical fitness. 】

Although it is only a short sentence, it is enough to show the value of this fish. As for those with golden lines on their backs, most of them will live longer and have a stronger effect!

The Ice Spirit Fish is really a baby!

Zhang Chen was naturally not polite, and concocted a fierce operation. The large net swayed and retracted back and forth, and fish were caught.

These are good or bad fish, he was afraid that he would not survive if he put it directly into the space backpack, so he deliberately took out the fresh-keeping box, filled it with a large amount of pool water and then rolled the fish in. After wandering in the pool for a while, he caught a lot of ice spirit fish.

The fish in the waters became sparse, and he continued to dive in with a sense of conscience. When you encounter a large number of fish, you catch them, and by the way, you use a container to fill the water in the deep pool.

The further down the cold becomes, the smaller the number of ice spirit fish that can survive, all of them are about a foot in size, but the golden lines on their backs are deeper. There is even a cold ice spirit fish with golden lines on its back that begin to spread to its body.

If it happens, Zhang Chen will naturally not be polite, and he will catch it first. Relying on the protection of the natural enchantment and not afraid of water pressure, and with the blessing of the system-assisted convergence breath and 'disappearing', it swims and rages like a ghost.

I don't know how long it has been, and I don't know how deep!

It's just that as he dived down, the water pressure became more and more intense, and even some cold qi penetrated the natural enchantment and poured into his body, making it painfully cold. Let his blood boil again, desperately resisting the cold erosion.

Fortunately, I was able to resist it for the time being, and I was still able to dive down smoothly. It's just that this speed is getting slower and slower, and the cold air is penetrating more and more.

The natural enchantment has an unstoppable trend!

Zhang Chen's heart trembled, and he wanted to retreat quickly and wait until his strength became stronger before trying. However, when I looked down, I could vaguely see the bottom silt below.

At most, it is only a few tens of meters!

It's all come to this point, and it would be a shame to give up.

Wealth and danger are sought!

He gritted his teeth and drank the two bottles of Evolution Essence in pain, and then chose to continue diving to the bottom of the deep pool. It took all the strength to reach the bottom of the cold pool.

At the bottom, Zhang Chen's vision suddenly became clearer, although he still had some limitations, but he could see and distinguish things within a hundred meters.

At the bottom of the vast cold pool, there was nothing but huge rocks. Even the Ice Spirit Fish bred in the Extremely Cold Land was gone.

This made him very disappointed, is there nothing! The constant influx of cold air made him very urgent, and he was unwilling to swim quickly in the waters a few meters from the bottom of the pool, trying to detect anything unusual in the waters.

There was not even moss at the bottom of the pool, except for the huge rocks and silt. The only good news is that the stones appear to be some kind of metal ore. It was discovered out of curiosity by smashing a piece with an iron-blooded battle axe.

Collected a few along the way, as for those buried there was simply no time to dig.

"Hey, how can there be any light there?"

Zhang Chen was swimming around in the water, and suddenly noticed a faint light flickering in the left direction. It's faint, but it's clear in the dark.

He immediately turned around and swung his legs and swam quickly towards the area. The closer you get to that side, the more chill seeps into the natural barrier.

Could it be the source of the cold?

Zhang Chen thought of this for the first time, and involuntarily accelerated his swimming. It seems that I saw a lot of blue mussel shells half-hidden in the silt at the bottom of the pool.

There are not many of them, almost more than twenty.

The big bathtub is big, and the small one is only the size of a palm, and the blooming circles of blue light are very extraordinary. The blue mussel shell, I wonder if there are pearls in it?

It's just that the situation is worrying, and he doesn't have much time to care, and he quickly swims in the direction of the light. When you get closer, you find that it is coming out of the mud. With streams of ice-blue cold air spreading outward and merging into the pool.

Isn't this the cause of the cold pool?

Zhang Chen could clearly see the cold air that was constantly venting outward, so he could naturally guess it. At this time, more and more cold air penetrated into the enchantment, making his body a little numb from the cold, and there was no time to delay at all.

He pulled out a sapper shovel and quickly cleaned up the surrounding mud. Soon a large area was cleared, and the source of the cold appeared, which was an ice-blue crystal, almost a man high, and fell slanted into the mud.

During the cleanup, three small crystals the size of a palm were found. Touching the backpack, Zhang Chen's entire arm almost froze into an ice lump. Half of his body stiffened for a long time before he gradually recovered.

【Eternal Ice Crystal, Legendary Thing!】 】

Because of this, the information fed back by the identification technique let him know what it was. With only these eight words, the lack of information shows that it is extremely precious.

The eternal ice crystals lying quietly in the mud are as brilliant as diamonds!

Legends can show their value!

At this time, there was an ancient sword inserted on this ice crystal, the long sword was ice blue throughout, the sword body was about three feet long, the shape was simple, and the light was dense. Even though I don't know how many years have passed, it is still cold.

Look at the gap above, the pieces that fell on the ground before fell from above.

Zhang Chen's eyes were fixed on an arm in the eternal ice crystal, broken shoulder to shoulder, I don't know how many years have passed, it is still alive, and even the blood can be clearly seen, it is a left arm, and there is a quaint ring on the index finger.

Isn't this a storage ring?

Could it really be a relic of ancient times?

Witnessing this strange scene, Zhang Chen was not as incredible as the others, shouting. Instead, he calmed down and his head spun quickly.

I wonder if the giant blue tortoise is attracted or guarded by this thing. Eternal Ice Crystals may be the treasure of some ancient power from a long time ago.

And the ancient sword stuck in it......
