Du Fan's face sank, and suddenly, the cold wind was blowing nearby, and his flesh and blood were icing at a speed visible to the naked eye, and in an instant, it was clear and shining, flawless, transparent inside and out, even the internal organs, blood vessels and bones were clearly visible, and the whole body was like pure ice, with sharp edges and corners, just like an ice sculpture.

An ice fist struck out like lightning, slamming into the gap between the two door panels, and a loud bang rang out, causing the void to shake for a while.

"Boom, boom, boom......" Du Fan's arms moved together, with the momentum of destroying the world and destroying the earth, the sound of thunder was endless, the seven-story white tower trembled, and with the passage of time, the two door panels finally appeared a little loose.

Although Huang Tianlingbao is not bad, but after all, no one drives him, and his independent consciousness alone cannot stop Du Fan's continuous attack, and after dozens of hundreds of punches like a storm, there is a "click", and the two door panels move back, revealing a gap.

At this moment, a black light flashed, and the ghost door appeared out of thin air, spread flat on the ground, stuck between the gap between the two door panels, making it impossible to close, and slowly expanded, making the space in the door gap larger and larger.

Du Fan took one step and crossed the door, and at the same time, the fire map was three feet above his head, and the red mangs were flourishing, and the wisps of fiery red flames fell down like a water curtain, forming a ring, protecting him inside, impermeable.

To this day, Du Fan, who has opened up the three secret realms of the human body, has cultivated to be equivalent to the Great Perfection of the Distraction Period in the traditional sense, but he still does not have the conditions to fully urge this Huangtian Spirit Treasure, at least a big difference of one realm, but it is not a problem to only stimulate part of the power of this treasure like this.

As soon as Fang entered the tower, there was immediately a wave of frozen power swept in, it was an endless white mist, the attribute was extremely cold, it could freeze the void in an instant, and then turn into countless chips, which was more complete than the mirror falling to the ground.

However, this white mist of frozen power could not shake the curtain of red flames that fell from the fire map, and it was cut off.

Du Fan had expected this, and when he saw this, his face was as usual, and he took powerful steps, surrounded by the fire curtain, and strode towards the depths of the sixth layer of the pagoda with incomparable frozen power.

After a short time, Du Fan passed through the white mist and came to an open area.

This place is full of black ribbon-like substance, very rich, if you use the secret technique of the Heavenly Eye to observe carefully, you can also see a blue gossamer, all over the black substance, a kind of yin to soft avenue law looming, this is the power of the source, the attribute of the water of the five elements.

Du Fan's eyes lit up, and he immediately took out the Three Realms Picture Scroll and unceremoniously took away all the water origins here.

After doing this, Du Fan had no intention of continuing to explore, and turned around and left.

After a cup of tea, Du Fan walked out of the pagoda, retreated with his whole body, and put away the ghost romon, the fire map, the water of the yellow spring and other things.

As for the seven-story white pagoda of the Yellow Sky Spirit Treasure in front of him, it is impossible to say that he is not moved at all, but Du Fan also understands that this treasure has already been sacrificed and recognized by the Lord, and it is obviously unrealistic to forcibly take it away with its high grade and great power.

......

A few months later, Du Fan hung in the sky, his brow furrowed.

After such a long time, under the shroud of his divine thoughts, it can be said that the entire Northern Underworld family "dug three feet into the ground", but there was still no shadow of those ancestors, during which he also set foot in seven or eight dangerous places, and killed in and out several times, but he also failed to make a contribution, but he almost suffered a big loss at the hands of a mutant creature who did not know the race.

"Shouldn't the Northern Hells family be the only one ancestor left, the Fifth Ancestor, and the other old guys have all returned to heaven...... Du Fan couldn't help but have such a thought in his heart.

"Instead of guessing here, it's better to ask the Realm Mountain Instrument Spirit. ”

After making up his mind, Du Fan immediately swiped his hands, and the pitch-black cracks appeared, shuttling through the void.

......

Coming to the foot of the Boundary Mountain, Du Fan suddenly hesitated, although the old man on the top of the mountain was a Boundary Mountain Instrument Spirit and had some relationship with him, but he did not show much affinity for him, at most he was stronger than a stranger, and it was far from the level of knowing everything.

However, that old man seemed to attach great importance to Chu Ling'er, and even loved it, if there was this girl by his side to help, then the result might be different.

Thinking of this, Du Fan immediately released Chu Ling'er, and after explaining a few words with divine thoughts, the two went up the mountain together.

In fact, as Du Fan expected, this time the old man directly ignored him, and only said that six years later would be the agreed period, when the boundary mountain would be far away from the Kyushu continent and the extreme north, and from then on, the two areas would be unimpeded, and there would be no barriers.

"Senior, if you know, tell us, Master, he is also for the common people in the world. Seeing that the figure of the old man was faint and about to disappear, Chu Ling'er spoke eagerly, and his voice like a heavenly voice floated far away.

"The four ancestors of the Northern Underworld are all on the Arctic Mountain. Before the old man's figure disappeared, the answer was finally given.

"Arctic Mountain, no, throughout the ages, isn't there only one lawless person who has entered the belly of the mountain, and then I, a latecomer who has obtained the inheritance of lawlessness......" As soon as he said this, Du Fan suddenly woke up, it turned out that he had been stuck in a blind spot before, outsiders really can't enter the mountain, but they didn't say that they can't climb.

Although the Arctic Mountain has its own natural prohibition, which has broken the idea of climbing for the vast majority of people in this world, Du Fan asked himself, if he uses all his strength to assist the treasure outside, he dare not say more, but a few thousand zhang is still not a problem, what he can do, of course the ancestor of the same level can also do it, not to mention that the background of the Northern Hell family is far deeper than that of him, who is only more than three hundred years old.

"Senior, can you tell me where you will go after you leave?" After a moment, Du Fan shouted loudly and asked about something else.

On the vast snowy peak, only Du Fan's voice was echoing, but no one responded.

Chu Ling'er looked at Du Fan and cast a look of inquiry, but Du Fan shook his head and signaled that there was no need to ask.

......

This is the second time that Du Fan has stood at the foot of the Arctic Mountain at close range, the mountain is straight, towering, breaking through the clouds, extending endlessly, and he can't see where the top of the mountain is, as if a giant sword pierced the sky.

Feeling the majesty of the Arctic Mountain, Du Fan's heart couldn't help but flash the handwriting carved on the stone wall by lawlessness.

"Arctic Mountain, Antarctic Mountain, the only two places in the Blue Star Realm that I can't see. ”

This sentence alone is enough to explain the mystery and extraordinariness of this mountain.
