The billowing cold air continued to permeate from the crack on the jade platform, and almost in an instant, everything in the underground altar was frozen again. This kind of cold air rolling out, Rao saw it with Du Fei's strength, and he also twitched the corners of his mouth slightly, the exercises he cultivated were ice-based, but for this kind of oppressive cold, he probably couldn't withstand it.

Fortunately, the cold air that came out of this rolling out did not last long, and after a while, this turbulent state of affairs had slowly disappeared, and was replaced by a slight cold air that continued to diffuse out, which made people feel a little frightened.

"It seems that this is really the Ten Thousand Years of Xuanbing!" Sensing some kind of fluctuation under that gap, Du Fei couldn't help but lick his tongue and said lightly.

"Well, according to the records in the Danwang map, it shouldn't be wrong, and looking at this situation, this piece of 10,000-year-old Xuan Ice doesn't know how long it has been sealed under this altar, if the master can refine it, the strength will definitely be able to improve by leaps and bounds again!" Xiao Bai also said excitedly.

"Perfect the Ten Directions Ice Demon Dao!" Du Fei pursed his lips slightly, and only after a moment did he make a move with his right hand, without the slightest hesitation, his figure instantly jumped down towards the gap.

In the gap, there is a dark cavern, I don't know how deep it is, and there is a constant cold rolling in it, which makes people tremble for a while.

And Du Fei didn't hesitate at all, and his figure moved slightly, and he quickly fell downward. As he moved, the surrounding caverns were all rushing upwards, apparently as fast as they were.

The surrounding caves are extremely obviously covered with layers of ice crystals, these ice crystals are obviously condensed layer by layer, I don't know how strong it is, and it can also be seen from these ice layers how many years this 10,000-year-old ice has existed here.

"Master, be careful!"

At the moment when Du Fei sighed in his heart, Xiaobai suddenly said quickly.

Hearing this, Du Fei's face was slightly shocked, and a transparent wings had quickly appeared behind him, holding his figure into the air, and then he saw that an extremely rich cold current swept in instantly!

When staring at this cold current, the corners of Du Fei's eyes twitched slightly, and he naturally understood that this was the cold air attached to the Ten Thousand Years Xuan Ice itself, as long as ordinary people touched it, they were afraid that they would be frozen into ice.

"How do you go down?" staring at the cold air for a moment, Du Fei said in a low voice.

"The Ten Directions Ice Demon Dao was originally supposed to be created to imitate the cold qi of the Ten Thousand Years of Ice Demon, there should be some kind of mysterious connection between the two, as long as the master wraps his whole body with the Ten Directions Ice Demon Qi, he should be able to get through this level!" Xiao Bai thought for a moment before saying quickly.

"Well, I know!" Du Fei nodded quickly, and then the marks on his hands changed violently, and he immediately saw that the rolling true qi instantly formed a circle of light, wrapping around his body.

At the moment when this aperture was formed, I saw that the cold current had surged to Du Fei's side, and immediately wrapped Du Fei's whole person in it at an extremely fast speed.

"Whew-"

As the cold current spread, Du Fei clearly felt that the blood and qi in his body seemed to be condensed in an instant, and a faint layer of ice flowers appeared on his body, but fortunately, it was protected by the ice demonic qi of the ten directions, so this kind of cold was still in an acceptable situation for Du Fei.

It's just that he cultivates the Ten Directions Ice Demon Dao, and in this place, it's really hard to imagine what a terrifying scene it would be if an ordinary powerhouse encountered this kind of cold current.

However, Du Fei didn't have time to sigh for others here at the moment, he stayed in mid-air for a few minutes, and only after this cold current disappeared did his toes slam a little in mid-air, and then his figure continued to fall down quickly.

In the following time, Du Fei encountered several cold currents, and each time this cold current was a few points stronger than the last time, and in the end, Du Fei had to use the mixed pill method and bronze forging body skills to forcibly improve his strength to the half-step Martial Sect Xiaocheng realm, so that he could barely resist the cold power in these cold currents.

After this wave of cold current, Du Fei's eyes finally lit up slightly, and immediately in his line of sight, he saw a translucent blue altar, slowly appearing in his sight.

Seeing this altar that seemed to be made of ice cubes, Du Fei's heart was also slightly happy, but he did not relax his vigilance, but more carefully urged the true qi in his body, and after a while, his figure slowly fell on the altar.

"Click-"

As the soles of Du Fei's feet fell, the air around him seemed to surge slightly, and then he saw that in the center of this altar, there was a stone platform, and on the stone platform, there was a strange stone shaped like an eyeball, probably the size of a human head, and at this moment, in a fist-sized hole above the stone, there was a trace of cold air overflowing. And the kind of cold air that overflowed was a little more amazing than the cold currents just now.

Looking at this scene, after a while, Du Fei's face moved slightly, and after staring at the scene in front of him for a moment, he hesitated slightly: "This is... Ten thousand years of Xuanbing!?"

"It should be, it's just that the 10,000-year-old Xuanbing shouldn't look like this......" Xiao Bai hesitated for a moment before making a careful gesture to Du Feibi, and then his body moved slightly, and he had already landed on the stone platform.

After standing on the stone platform and staring at the strange stone platform for a moment, Xiao Bai's face moved slightly, and then he said with a bit of abruptness: "I see, it may be that this 10,000-year-old Xuan Ice has existed for too long, so the essence of it has been all solidified together at this moment, which is much more difficult than we imagined to refine it!"

"Then is there a way to refine it?" Du Fei said with a slightly ugly face.

"Yes, yes, but it's not as easy as we thought before......" Xiaobai's face was also a little ugly, and it hesitated for a moment before whispering.

"What do you say?" Du Fei frowned.

"The energy of this 10,000-year-old ice has been concentrated in one point, so the only way to activate it is to destroy this stone, but in that case, the violent energy inside may instantly turn into the most violent ice tornado! And this kind of ice tornado is extremely dangerous! It is definitely not easy to refine it! This is completely different from the slow refining we imagined before!" Xiao Bai said in a low voice.

"This is the only way?" Hearing this, the corners of Du Fei's mouth twitched slightly, the cold current in this cave was so yin, if the energy in this 10,000-year-old Xuan Ice exploded into a tornado, I am afraid that refining him by himself would be no different from killing himself.

"There's no other way...... Or, master, how about you give up here? I don't believe it, there will be no more 10,000-year-old ice in this thousand-year-old ice realm!" Xiao Bai twitched the corners of his mouth and hesitated.

"I came here with all the hard work, so I just gave up?" Du Fei's face sank slightly, and he said lightly.

"However, master, if you insist on trying it, it's not impossible! You know, although the ice tornado transformed by this 10,000-year-old Xuan Ice is extremely powerful, if you can withstand that kind of cold and refine it, then I am afraid it will be of infinite benefit to the master in the future for you to seize the Ice Lotus Pill. You must know that the Ice Lotus Pill is the Yin and Cold Venerable between Heaven and Earth, and when we encounter that thing, it is the Ten Thousand Year Xuan Ice, and we have to retreat! Although we have the Dan King's method of taking orders, if we can refine this Ten Thousand Year Xuan Ice, the benefits to us should not be small!" Xiao Bai's eyes rolled slightly, and after a while, he said a little strangely.

"Is there any other benefit?" Hearing this, the corners of Du Fei's eyes twitched slightly, and after a while, he gritted his teeth slightly. In the past year, he hasn't done anything in order to cultivate, and now it's just an energy transformed by 10,000 years of Xuan Ice, can he still help himself?

"It seems that the master has made up his mind?" Seeing Du Fei's appearance, Xiao Bai, who knew him well, smiled faintly and said, "In that case, sit down cross-legged, remember, the only one who can refine the energy of the Ten Thousand Years of Xuan Ice is the Ten Directions Ice Demon Dao!"

"You break the last seal of this thing!" pursed his lips, Du Fei finally gritted his teeth and sat down slowly, then took a deep breath and said in a low voice.

An inexplicable taste flashed in the depths of his eyes, and after a while, Xiao Bai nodded slightly, and then after he signaled Du Fei to release a little spiritual power, his little hand was slightly touched, and he suddenly saw that his spiritual power turned into a spear, and it slammed into that strange stone!

"Whew-"

As the spiritual power spear blasted down, the strange stone trembled slightly, and the movement that had been slowly releasing the cold qi disappeared in an instant, and immediately on the surface of the stone, it was quickly covered with spider silk-like cracks at a speed visible to the naked eye!

"Ding—"

With a crisp sound, the thin layer of stone instantly cracked, and immediately I saw that a blue cold current swept up from it in an instant, and in just a moment, it turned wildly, forming a cold ice tornado. And the cold air in this cave was also absorbed by the cold tornado in a single breath! And after absorbing so much cold current, the cold tornado faintly appeared a bit of black color......

On the huge altar where the "Click...... Click" place was sitting, several cracks slowly appeared, and then the edge had fallen off quickly, and it was just a moment of breathing, and the huge ice tornado almost covered the entire altar......

Looking at this scene, the corners of Du Fei's mouth twitched violently, and without the slightest hesitation, the bronze forging body skill and the mixed pill method were activated again, and the mark in his hand changed, and the powerful ten-sided ice demon qi broke out in an instant!

"Whew-"

As if sensing something, the huge ice tornado suddenly shook, and then the howling cold wind seemed to have found its target, instantly spreading towards the place where Du Fei was.......

"Boom-"

In the next moment, a cold snap came to the body! A huge energy fluctuation exploded in an instant at this moment!
