The cave is deep and has a heavy chill.

With the strong body that woke up, standing at the entrance of the cave, blown by the cold wind, they were all shivering.

"This cold air is too terrifying, I'm afraid that the martial cultivators below the Star Realm will be frozen into ice sculptures, right?"

"And ...... Just the cold air at the entrance of the cave is so terrible, so what kind of terrible thing is in this cave?"

"The physical body is not bad, but with the physical body alone, I want to resist the cold here, but I can't. After Wu Zu finished speaking, he took the lead and walked towards the cave.

With his strength, he is naturally not afraid of the cold wind.

Su Xing gritted his teeth, had to follow, as soon as he entered the cave, the cold suddenly worsened, and he had to run the cultivation, turning the cultivation into fire attribute power, which was able to resist the cold that kept invading the body.

After walking for a while, the road came to an end, and there was a cliff at your feet.

Beneath the cliff is not a dark abyss, but a bright light.

When Wu Zu came here, his footsteps still didn't stop, stepping out of the cliff and falling down. When he woke up and saw this situation, he could only keep up.

Whew!

The wind was whistling in his ears, and the cold wind was like a knife, and when it slapped on his face, there was a tearing pain.

Soon after, Awakening stepped on the ground with both feet, and he calculated the distance, and came to the bottom of the entire mountain.

As far as the eye can see, there is a white world covered in snow and ice.

The ground is covered with a thick layer of ice, and even the surrounding cliffs and rocks on the dome are covered in ice.

And the temperature here is also terrifyingly low, and even the powerhouses in the early stage of the Star Realm are estimated to be completely frozen when they come here.

Awakening had to run his cultivation with all his might, so he simply stepped into the gate of the peak, assisted by the power of water nature and the power of wood nature, so that the water attribute cultivation reached the strongest state, so that he could barely resist the erosion of the cold air.

But in this way, his cultivation consumption speed also became extremely fast all of a sudden.

"Even if my cultivation is strong, but under such a sharp consumption, at most, an hour will be exhausted. "When I woke up and secretly estimated it, I was shocked.

"Cultivation is indeed strong, dozens of times that of martial cultivation in the same realm, this is one of the capitals of your cross-border battle, and seeing that your method of running cultivation is quite ancient, I think you have obtained some kind of ancient exercise!" Wu Zu's voice sounded slowly.

Su Xing was secretly shocked, he didn't expect Wu Zu's eyesight to be so old and spicy, and he even guessed the exercises he cultivated.

Indeed, the Ten Thousand Qi Confluence Technique is the practice of the Ten Thousand Laws Pope in ancient times, and it is precisely because of this practice that the cultivation of awakening is many times stronger than that of martial cultivation in the same realm.

"However, although the cultivation is strong, in terms of refinement, it is a mess. Wu Zu said.

"Refinement?"

"Why? Haven't you heard of this word?" Wu Zu glanced at Su Xing lightly, and found that the latter was still confused, so he patiently explained: "The degree of refinement, to put it bluntly, is the degree of condensed refining of cultivation. The same large Yuan Hai, because the refinement degree of cultivation is different, the power that martial cultivation can burst out will also be different......"

It's easy to see why.

For example, a glass of water and a glass of slurry, whoever is thicker will have a heavier mass.

In terms of cultivation, it is not the weight that is compared, whoever has a higher degree of refinement, then the power that cultivation can burst out will be stronger.

"Now, I'll simulate your cultivation and take a closer look. ”

Wu Zu's voice fell, and a wave of cultivation fluctuations appeared on his body, which was not much different from awakening, all in the middle of the Zhongtian Realm.

Bang!

Suddenly, Wu Zu raised his hand slightly, and a terrifying power surged in his palm, making Su Xing instinctively frightened.

"This power ......" woke up and found that the power that erupted in Wu Zu's hands with the same cultivation was at least fifty percent stronger than in his hands.

"Do you see it clearly?" Wu Zu dispersed to cultivate.

"See clearly. Su Xing nodded, when he was carefully observing just now, he found that Wu Zu's cultivation burst out was incomparably condensed, giving people an indestructible taste.

"Cultivation is a continuous breakthrough, brave and radical, this is a good thing, it shows that you are talented, but sometimes it can also be a bad thing, because cultivation is improved too quickly, and without the baptism of time and time, the foundation is inevitably unstable. Wu Zu said.

The word refinement is not widely circulated.

Because of this problem, it basically only appears in one kind of person, that is, genius and demon.

The speed at which the cultivation of genius demons is improved is many times faster than that of ordinary martial cultivators, which leads to the lack of refinement in cultivation.

On the other hand, ordinary martial arts cultivators, their cultivation has improved slowly, and every point of cultivation has gone through the grinding of years, so the foundation is very solid.

"Wake up, everyone's cultivation refinement is different, and in general, the faster your cultivation improves, the worse your refinement will be, so I will say that you are a mess in this regard. Because your cultivation is improving faster than anyone I've ever seen. Wu Zu said again.

Wake up silently.

What Wu Zu said was indeed reasonable, and he had no way to refute it.

"However, with me, you can solve this problem easily. Probably seeing that Su woke up with a good attitude, Wu Zu smiled again.

Speaking of this, he smiled again: "Wake up, I came out of the same era as Li Zu, do you know what kind of status we had in the Life and Death Dou Sect at that time?"

"The disciple doesn't know, please Wu Zuming said. "Awakening is quite interested.

"At that time, Li Zu was the senior brother of Zixiao Peak, the first core disciple, and he was a genius demon in the eyes of the people, and he was feared by the Black Emperor Gate and the Killer Palace. ”

"And I'm not even a core disciple, I'm just an inner disciple. ”

"When Li Zu was three hundred years old and became the head of the sect, I barely became an inner elder. I am compared to him, one is heaven and the other is earth. ”

When Wu Zu said this, he was also a little embarrassed.

Su Xing was even more stunned, he didn't expect that Li Zu would actually be the head of the Life and Death Fighting Sect, and if you calculate the time, then Li Zu is estimated to be the previous head teacher, that is, Zhu Long's master.

"No wonder, Zhu Long respects Li Zu so much......"

What made Su Xing even more unexpected was that Wu Zu was so much worse than Li Zu.

"Li Zu has been in charge of the Life and Death Dou Sect for more than 400 years, and since then he has been succeeded by Zhu Long. Wake up, do you know what kind of cultivation I did when Li Zu abdicated?"

"Wu Zu, please speak clearly. Wake up and say immediately.

"Supreme!" Wu Zu's eyes obviously had a touch of pride, "When Li Zu abdicated, when he and I were both seven hundred years old, I stepped into the supreme position. ”

"Also, I had a fight with him and it was a draw. ”

"What?"

Wake up with a face full of surprise.

As martial cultivation grows older, its potential will slowly be exhausted, and it will be difficult to continue to improve its cultivation, especially in later years, as the body's functions decay, its cultivation will continue to decay.

But I don't want to, Wu Zu can still step on the supreme position when he is seven hundred years old, which is absolutely very rare, it is simply a counterattack.
