The third is more sent.

Wu Aotian simply took out the Tower of Heavenly Fire, although Lily had already escaped from it, but the power of this Tower of Heavenly Fire had not decreased much, what was reduced was only spirituality, after all, the spirit body that was originally entrenched in it Lily had left, but fortunately, she still had a trace of soul in it, so as not to make the Tower of Heavenly Fire look like a completely dead thing.

Hiding in the Tower of Heavenly Fire and sitting cross-legged next to Heavenly Fire, Wu Aotian felt the slightest warmth.

Hell, this kind of place is really damn bad, ordinary spiritual cultivators don't dare to come here at all, and if they come here, there is only one end, and that is to be frozen into popsicles.

In the Eight Desolations Gathering Spirit Ding, Liu Ruxue sat cross-legged, quietly closing her eyes and cultivating, absorbing the energy of the Moon Lingzhi Spring, carrying out the most critical tempering, and after crossing this pass, she would be able to break through and become a powerhouse in the Phantom Spirit Realm.

With the strength of the Phantom Spirit Realm, coupled with the particularity of Heaven Annihilation, and the Great Killing Technique, I am afraid that even Liu Ruxue in the First Heavy Realm is definitely not an ordinary existence, even Wu Aotian is looking forward to it, how far can Liu Ruxue grow in the end?

In the process of Wu Aotian's growth, he met a lot of friends and a lot of enemies, trampled the enemies under his feet one by one, and walked towards a more powerful class with his friends.

Leng Feng, Mo Yu, Dong Yuanyuan and others, although their strength has also improved rapidly, they have reached the Heavenly Spirit, and they are already considered good powerhouses on the mainland, but when this demon beast attacked, their strength seemed to be too low, so that they could no longer fight side by side with Wu Aotian.

The only strength that can keep up with Wu Aotian's crazy progress is only Liu Ruxue, if there is no outbreak of demon beast attack, Wu Aotian will also leave Liu Ruxue far behind in terms of strength, but the special event of the demon beast invasion has made Liu Ruxue's practice of the great killing technique have a place to use, thus bursting out of huge potential, catching up with Wu Aotian's strength in one fell swoop, and still being able to accompany Wu Aotian's side, the two live and die together, and face the powerful enemy together.

For the future, no one knows how it will be, the strength of the demon beast makes humans not sure that they must be the victors, but no matter what, this war will continue until one side is completely victorious.

In the vast ice field, there is no life, not even a single plant can be seen, some are just vast blocks of ice.

Without any coordinates, without any references, Wu Aotian was like a fly, constantly advancing towards the north on this vast ice field.

This round and round is four months.

Liu Ruxue had already completed the absorption of the energy of the Moon Lingzhi Spring, and after her body was tempered, she finally broke through and successfully advanced to the Phantom Spirit Realm.

Xiao Jin's speed of devouring demon cores is getting faster and faster, after all, its strength is getting stronger and stronger, and the energy it needs is also increasing, when it is devoured first, it is eaten by a few few, slowly dozens, hundreds, and in the end, it is hundreds, thousands of them are devoured like this, and the tens of thousands of demon cores in the Eight Desolations Gathering Spirit Ding have been swallowed by it.

Xiao Jin, who devoured such a huge amount of demon core, also fell into a deep sleep again, and its strength also soared like a ghost, this speed made Liu Ruxue and Wu Aotian extremely shocked, in just a few months, Xiao Jin's size has almost grown to the size of an adult golden dragon, and its strength has also been promoted again, reaching the realm of phantom spirits.

If it is a normal golden young dragon, it will take at least hundreds of years to grow into the Phantom Dual Realm, but with this huge amount of demon core stimulation, Xiao Jin has already reached it in only one or two years, and the gap between them is not small.

Although shocked, Wu Aotian and others can still understand, after all, those demon cores, but from tens of thousands of demon beasts with demon cores, those demon beasts, even if there is only one demon core, but they can also achieve a very fast growth rate, now Xiao Jin has eaten so many demon cores alone, and his strength has skyrocketed, but it also makes people feel that it should be so, this is like a demon core can create a strong person, but you can eat all the demon cores that create tens of thousands of strong people alone, don't you become a super strong existence, then do you still say the past?

There is still more than a year before the demon beast attacks, according to Xiao Jin's eating speed, Wu Aotian estimated that he touched this demon core, and he didn't know if it was enough for him to eat, but fortunately, Xiao Jin didn't have to eat so much every day, but every time he ate like crazy, he would fall into a long sleep, and every time the long sleep ended, his strength would soar wildly, and the next time he ate more and more, and the time of long sleep would become longer and longer......

Liu Ruxue stayed in the Eight Desolations Gathering Spirit Ding to cultivate, although she had a lot of pills to eat, but the speed of her strength progress slowed down, and without the continuation of killing, her strength progress was far reduced.

In this regard, Wu Aotian had no way.

Wu Aotian sits in the Tower of Heavenly Fire every day, he has nothing to do, except for cultivation, he still cultivates, even with the help of the Eight Desolations Gathering Spirit Ding, with the Eight Desolations Burial Divine Technique, although Wu Aotian's strength is progressing faster than Liu Ruxue, but if he wants to advance, he is still too far behind, according to this cultivation speed, it is estimated that when the demon beast attacks in two years, Wu Aotian will not be able to enter the Phantom Dual Realm.

Although Wu Aotian was a little anxious in his heart, he couldn't help it, after all, strength was not a balloon, and it would swell up when he blew it.

The boring and monotonous days of flying made Wu Aotian feel a little anxious, after all, time was too tight.

Is there any ice on this ice field?

Just when Wu Aotian was getting more and more anxious, through the eagle eye in the sky, he saw a cloud of ice mist shrouded in the ice field again.

This is not the first time Wu Aotian has seen this kind of large-scale ice fog, when he saw the ice fog for the first time, Wu Aotian was overjoyed, thinking that he had found the ice spirit, but when Wu Aotian flew over, Qiu told Wu Aotian with great certainty that there was absolutely no ice spirit in this place, and there was not even anything yin or cold, that is to say, this ice fog was just an ice fog formed by some special conditions.

Wu Aotian was disappointed, but he also understood that ice fog is not only formed by ice spirits, but also formed in this long ice field, when some special conditions are met, this kind of ice fog will also be formed.

In these four months, Wu Aotian is like a comb, on this barren one-person ice field, like a comb, constantly flying repeatedly, combing the land of this ice field inch by inch, this is a very stupid way, but Wu Aotian really can't find a better way, fortunately, there is an autumn induction, so that Wu Aotian can fly directly at high altitude to detect whether there is something yin to cold, without falling to the ground to detect, otherwise, it is an impossible task.

In the past four months, Wu Aotian has discovered this kind of ice fog many times, but none of them have a good result, and now he has found it again, although Wu Aotian was surprised, but the degree of surprise was not as good as the first time.

No matter who it is, after many disappointments in a row, the feeling of surprise and anticipation will naturally weaken a lot.

But just when Wu Aotian controlled the Heavenly Fire Tower and flew towards the ice mist, Qiu's surprise voice suddenly sounded: "Hey, there is a feeling here, haha, there is something that is most yin and cold here, and there is ice mist, it must be the ice spirit!"

Wu Aotian was refreshed when he heard this, and he suddenly jumped up when he had been sitting cross-legged, and asked, "Really, are you sure there is an ice spirit?"

Qiu was also extremely excited, and laughed: "It doesn't have to be an ice spirit, but it is definitely a thing that is the most yin and cold, and it is also a super powerful thing that is extremely cold and yin, I think nine times out of ten it should be the ice spirit we are looking for!"

"A super-powerful thing that is the most yin and cold?"

Wu Aotian was also excited, and said with a smile: "Okay, after looking for four months, I finally found it, it's really the emperor's heart!"

Qiu was already impatient and shouted: "It's been said, hurry up, hurry up, that thing is hidden deep under the ice field, let's get in." ”

Wu Aotian nodded, and casually threw out thirteen heart swords: "You guide the direction, I'll drill the hole." ”

I don't know how deep this ice field is, and I don't know how long it has existed, the ice layer is extremely hard, ordinary weapons can't smash it at all, and the heart sword forms a rapidly rotating sword array, rotating rapidly in the air, like a huge drill.

"Here, here, just here, drill down, it's so thick and cold, haha, it's developed this time!"

Wu Aotian listened to Qiu's ecstatic voice, and for a while he was also infinitely motivated, according to the direction of Qiu's guidance, the sword array slammed down, and the thick solid ice layer instantly turned into countless ice slags, revealing a large hole with a diameter of tens of meters in the middle.

Wu Aotian still hadn't left the Tower of Heavenly Fire, as he continued to land, he had already felt more and more the cold air outside, the cold air was so violent, even more icy and colder than when he first went down into the deep sea!

The surroundings of the Tower of Heavenly Fire were already full of thick soldiers, and the cold penetrated into the tower through the Tower of Heavenly Fire, Wu Aotian was taken aback, and hurriedly drove the Heavenly Fire at the bottom of the Tower of Heavenly Fire, and the Heavenly Fire spread upward, covering the entire Tower of Heavenly Fire, and the blazing temperature blocked the cold and prevented the Tower of Heavenly Fire from being frozen and cracked.

Wu Aotian is very aware of the power of cold, even steel, in super cold weather, it will become extremely fragile, although this Heavenly Fire Tower is made of dark iron, but once the temperature is lower than the minimum temperature that it can withstand, it will also collapse.

The autumn in the Eight Desolations Gathering Spirit Ding, but he looked extremely comfortable, and shouted loudly: "What a deep cold aura, haha, this time my strength will definitely be greatly restored again, and then we will be able to dominate the world!"
