430 zhang, 450 zhang, 480 zhang......

As Yi Tian continued to dive, the cold air that kept surging around him became more and more amazing, and even faintly turned into substance, like a white mist in the water.

At the same time, there was a huge pressure everywhere that kept surging from all directions, and that terrifying pressure almost made Yi Tian's body unable to move, as if it was going to crush it into nothingness!

And when it reached four hundred and ninety zhang, it had faintly reached the limit that Yi Tian could bear.

Despite the protection of Xuanhuang Qi, the surface of Yi Tian's body was gradually covered with a layer of frost, and even his face was covered with many small ice slags, and the breath of the whole person slowly became weak.

However, although the cold air here was already extremely amazing, the fifth Xuan Nether Soul still showed no signs of condensing at all, which also made Yi Tian secretly frown.

"This is almost the limit of what I can bear, if I can't condense this fifth soul of the underworld, I may have to give up. ”

Although Yi Tian was extremely eager to successfully cultivate this Xuan Yin Seal, he was not without self-knowledge.

Now that Yi Tiantian has dived to an astonishing depth of four hundred and ninety zhang, and this place has almost reached Yi Tian's limit, according to what he thinks in his heart, I am afraid that when he reaches five hundred zhang, he may not be able to dive even if he tries his best.

491 zhang, 495 zhang, 498 zhang......

And just when Yi Tianxia dived to a full five hundred zhang, suddenly, an extremely cold intent that was much more violent than before instantly struck, almost without allowing Yi Tian to react, a thick layer of frost suddenly formed on the surface of his body, and the ice layer was still thickening, as if it was about to freeze Yi Tian into an ice cube.

"Not good!" Yi Tian's heart sank when he saw this.

Almost at the moment when the extremely cold intent hit, Yi Tian suddenly used his spiritual power with all his strength, and at the same time, the few Xuanhuang qi that swirled around the surface of his body also suddenly spun rapidly.

"Shattered!"

Yi Tian let out a soft cry in his heart, and at the same time, he only heard a "click" sound echoing, and the frost covering the surface of Yi Tian's body immediately shattered inch by inch.

But before Yi Tian could take a breath, his pupils suddenly shrank!

I saw that the white mist that had originally permeated the surroundings that had been turned into cold air had disappeared, and was replaced by a trace of blue that was visible to the naked eye like catkins, sporadically surrounding Yi Tian.

"It's ...... Chill!"

Yi Tian couldn't help but gasp, and then a solemn look surged in his eyes.

This cold marrow can only be produced in extremely cold places, and it is the dream of martial artists who practice cold attribute exercises, whether it is alchemy or used to cultivate exercises, it has incredible effects. And a rare thing like this, even if there is only a trace of it, is enough to sell it for a sky-high price in the outside world!

However, the cold marrow in front of him, which made countless martial artists flock to it, has become something enough to threaten Yi Tian's life at this moment, and what makes Yi Tian feel even more speechless is that the trace of cold marrow seems to have spirituality, and they are rushing towards Yi Tian one after another!

The speed of that cold marrow was extremely fast, and it had already submerged into Yi Tian's body in an instant, and in an instant, a strange cold feeling permeated the whole body, and even his thoughts became a little slower.

Sensing this scene, Yi Tian's face couldn't help but look a little ugly, and then he bit the tip of his tongue violently, and a sharp pain hit, making his mind instantly sober up a little.

At the same time, Yi Tian began to run the cultivation method of the Xuan Yin Seal with all his might, and that trace of cold marrow accompanied by spiritual power slowly operated around Yi Tian's body, which was almost several times slower than the previous cultivation, but the chill was too strong, making Yi Tian's eyes faintly covered with countless bloodshots, and his face was also exposed with green muscles, a hideous meaning.

However, when that cold marrow entered the Yi Tian Dantian, the spiritual sea below it was faintly condensed, as if it was about to be frozen.

But fortunately, this situation only lasted for a moment, and then the cold qi hovered straight over the spiritual sea, and then slowly rotated according to an inexplicable trajectory under the traction of Yi Tian's mind, and the vultures transformed into a fist-sized blue air mass.

"Roaring ......"

Almost at the same time as the blue air mass formed, a roar that was much clearer than before came out, as if it had been transmitted from ancient times, with a sense of desolation.

Suddenly, I saw the figure of a black python gradually become clear, and then I saw it take a big breath, and the blue air mass disappeared into its mouth, and its body also quickly condensed, as if it was semi-substantial.

"Roar!"

And to Yi Tian's surprise, the fifth Xuan Ming Soul was very different from the previous Xuan Ming Souls, as if the spirit was stronger, Wu roared, and then it actually transformed around Yi Tian's body!

At the same time, the previous four Xuan Nether souls also seemed to sense something, and they also conjured out outside Yi Tian's body one after another, and then they didn't see any movement, but the trace of cold marrow that permeated the surroundings suddenly shot towards Yi Tian!

Seeing this, Yi Tian's face couldn't help but change greatly, although due to the condensation of the Fifth Soul of the Mysterious Nether, the astonishing cold qi around him was gradually losing its threat to him, but if so many cold marrow were all coming, even if he had already cultivated the Five Souls of the Mysterious Netherworld, he was in danger of falling!

However, Yi Tian's worries were obviously superfluous, and before he could make any moves, he saw that the five Xuan Nether Souls around him suddenly rushed out, scrambling to devour the trace of cold marrow that was coming, and in the process of devouring, the illusory body was also gradually condensed.

Finally, after about a quarter of an hour, the five Xuan Shen Souls stopped devouring one after another, and each quietly surrounded Yi Tian, but the bodies of the five Xuan Shen Souls suddenly became semi-substantial, faintly exuding a strong meaning!

A hint of satisfaction flashed in Yi Tian's eyes, and then his heart moved, and the five Xuan Nether Souls quickly swept into his body, floating quietly above the sea of spirits.

"I don't know how many souls I can cultivate here......

After successfully cultivating the Fifth Soul of the Underworld, Yi Tian's eyes showed a hint of expectation, and then he looked at the darkness below, and then his body moved, and he swept down in an instant!

With the help of those five Xuan Nether Souls, Yi Tian almost effortlessly dived to a depth of six hundred zhang.

And during this period, Yi Tian also successfully condensed the sixth soul of the Xuan Nether, but to Yi Tian's disappointment, those souls of the Xuan Netherworld did not change in the slightest because of the condensation of the sixth soul of the Xuan Nether, and they still showed a semi-substantial state.

Although he didn't know why that kind of change happened before, Yi Tian vaguely understood that perhaps the degree of substantiation of the soul of the Xuan Netherworld was inseparable from the power it could exert.

As Yi Tian went deeper and deeper, the more cold marrow there was around, and in the end, it turned into a blue mist like the cold qi he had seen before, suspended around.

This made Yi Tian secretly frightened, if it weren't for the fact that this Xuan Qi Soul had such a mysterious effect, I am afraid that it would be impossible for him to come here, and the blue mist in front of him would be extremely unbearable even if a strong person from the Xuan Qi Realm came here.

And the ubiquitous huge pressure has also become the reason for hindering Yi Tiantian's diving, and the terrifying pressure contained in it can almost instantly press a master in the early stage of bone quenching into meat sauce, even with Yi Tian's current Xuanhuang body, he feels a lot of difficulty.

But even so, it still can't stop Yi Tiantian's footsteps.

However, when Yi Tianxia dived to seven hundred zhang, the blue mist that was permeating the surroundings gradually transformed into a dark blue color, and what shocked Yi Tian was that in the dark blue mist, there were four round beads the size of his thumb suspended in the area shrouded by his divine thoughts.

"Chilling Ice Beads!!"

If the cold marrow that he had seen before could surprise Yi Tian, then the cold marrow ice beads he saw now were enough to shock him!

This cold pith ice bead is the essence of the cold marrow, and its magic is far from being compared with ordinary cold marrow, but this small cold marrow ice bead, if it appears in the outside world, it is enough to make many Xuan Realm powerhouses crazy for it, and make psychic powerhouses excited!

However, with Yi Tian's current cultivation, even if he had the six souls of the Xuan Netherworld, the cold qi contained in this cold marrow ice bead was enough to make him instantly frozen!

Therefore, after calming down a bit, Yi Tian didn't think much about it, but began to cultivate this seventh soul of the Xuan Netherworld.

The pain during this cultivation was self-evident, a cold qi that was several times stronger than before suddenly rushed into Yi Tian's body, almost stopping the flow of blood in his whole body, and a feeling like being pricked by needles suddenly struck, and then a sense of numbness emerged again, almost making Yi Tian's torture worse than death!

However, under Yi Tian's extraordinary heart and perseverance, he managed to survive this inhuman torture.

At the same time, the seventh soul of the Xuan Netherworld was also rapidly taking shape.

Finally, after Yi Tian felt as if several years had passed, a roar that seemed to come from ancient times came out, and the seventh soul of the Xuan Netherworld suddenly took shape!

At the same time, just like the situation when the fifth Xuan Ming Soul was condensed, the Seven Xuan Ming Souls once again transformed outside Yi Tian's body, and the dark blue mist around them also quickly poured over, and they all submerged into the body of the seven Xuan Ming Souls, and these seven Xuan Ming Souls also moved from semi-substance to substance.

Fifty percent, sixty percent, seventy percent......

Finally, the seven souls of the Xuan Netherworld slowly stopped devouring, and the degree of their materialization also reached eighty percent!
