In a space cave mansion that covers an area of only three miles, Jiang Xiaotian, Xia Qinglian, Xiao Sehuo, and the Lulu clan brothers and sisters sat at a stone table a little bored.

"Alas, it's so boring! Du Long, this guy is so uninteresting, he went to his own space cave to cultivate alone, and he didn't let us go in and visit!"

Regarding the secrets of the Xuanling Small Cave Heaven and Qinglang Cave Heaven World, except for Xia Qinglian and Xiao Sehuo, even Jiang Xiaotian didn't know about it, and Du Long naturally couldn't leak this big secret to the Green brothers and sisters!

After all, there are not many cave worlds that can carry around the world with them, and there are not many in the entire immortal world, once it is leaked, it is too shocking, and even the two Xiao sisters only learned this secret after a long time of testing!

There is an unnamed mountain peak in Qinglang Cave, Du Long stands alone on the top of the peak against the whistling mountain wind, his eyes slightly closed, and he is constantly watching a picture simulated by the ring spirit Ling'er in his mind.

It was a virtual image, in which a tall man stood on the top of a mountain peak in the wind, and suddenly waved the war knife in his hand, which instantly cut through the air and fell forward, causing the fog to disperse and radiate.

This picture is the picture of the first-level sword technique of the intermediate attack formation, just like when Du Long was still outside the Haotian Capital when he was a child, in the waterhole under the cliff of Lingyun Mountain, he first practiced the Xuanyang Stacked Wave Sword Technique!

Ring Spirit Ling'er couldn't sense the mysteries of the Heavenly Dao, so she could only teach Du Long this powerful sword technique that could attract the power of heaven and earth to resonate by playing the screen of a certain stage of the sword technique!

It's just that this seemingly simple knife now is a thousand times more complicated and difficult than the one at the bottom of the cliff back then, and it can't be said at all!

Back then, Du Long only worked hard for a few days, and he learned the first style of the Xuanyang Stacking Wave Knife Technique, and the combat power bonus was directly doubled!

Now, in order to learn this seemingly simple knife method, it has taken him nearly a hundred years, but he can't even get started!

You must know that the first knife learned back then only had a double combat power bonus, and now if this knife is successfully learned, it will be a full 512 times combat power bonus!

In the Xuanyang Sword Technique, Du Long, who reached the Xuanyang Nine Stacked Waves, was 256 times the bonus of his own basic combat power with one sword, and it was too long for him to reach this realm!

Hehe, of course, it's too long to say here, that's relative to the people in the mortal world!

Compared with people in the fairy world, if you want to increase the combat power bonus of a level, you often use thousands of years and 10,000 years as the unit of measurement, and a hundred years is really nothing!

After watching the picture of swinging the knife for a long time, and comparing the trajectory of this knife with his Xuanyang Nine Stacked Wave Knife Technique, Du Long really wanted to find out the similarities and differences between the two!

It's a pity that the two have been compared for nearly a hundred years, and today's results are not much different, and there is still no result!

It can only be said that the Xuanyang Tenth Stack Wave Knife Technique, which has jumped to a large level, is completely different from the previous Nine Stacked Wave Knife Method, and there doesn't seem to be any commonality between the two!

In desperation, Du Long could only turn over his hand and take out the Red Flame Slash that he used the most easily, and then waved the war knife forward while watching the virtual picture of the Ring Spirit Ling'er, wanting to find the artistic conception of attracting the power of heaven and earth to display the Xuanyang Ten Stacks of Waves Knife Technique!

One, two, three......

So the feeling of constantly swinging the knife to find the ten stacks of waves in Xuanyang, but unfortunately, after swinging an unknown number of knives in succession, none of the knives could succeed, because it was not the artistic conception of one to nine stacked waves, Du Long swung so many knives that even the power of heaven and earth could not be triggered once!

"Damn!" Seeing that the time for sword technique cultivation was almost complete, Du Long couldn't help but burst into a foul mouth in frustration.

For nearly a hundred years, as long as he had time to cultivate, he would arrange time to cultivate the Xuanyang Ten Stacks of Wave Sword Technique, after so many years, he didn't know how many times he had swung his battle knife like this, but unfortunately, he had never succeeded without exception!

"If he continues like this, I'm afraid Lao Tzu will even forget the artistic conception of the Xuanyang Nine Stacked Waves Knife Technique!" Du Long muttered depressedly before continuing to swing the knife, but this time he was not cultivating the Xuanyang Ten Stacked Waves Knife Technique, but the Xuanyang Nine Stacked Waves!

Because of the continuous failure of cultivating the Ten Stacked Waves for a long time, in order not to let himself forget even the Nine Stacked Waves, Du Long had to review the Xuanyang Nine Stacked Waves for a while after cultivating the Ten Stacked Waves every day, which was very necessary!

Boom!

The red flame slash was instantly sheathed, and he was put away by Du Long when he turned his hand, and finally finished the cultivation of the sword technique, and he was ready to start practicing the next project - Fengxing footwork!

At the top of the nameless peak, a cyan figure flashed back and forth there, sometimes to the top of the treetops, sometimes flashed over a raised boulder, the whole person's movement trajectory was both ethereal and weird, and the speed was so fast that ordinary people would definitely mistake it for a ghost!

As one of the several major exercises handed over to Du Long by Jieling Ling'er, this set of popular footwork will definitely have a shocking effect in the later stage of cultivation, but unfortunately, Du Long's cultivation of this set of footwork has reached a bottleneck, if he can't break through this bottleneck, no matter how much he cultivates, he will stop here at most.

Fengxing footwork is divided into several realms, the first is into the micro realm, the cultivator is familiar with the basic steps, and can move quickly without touching the stones under weight-bearing conditions, this heavy Du Long has already reached it at a very young age!

Second, after the operation of the wind footwork, it can move on the water surface with force, which is also called the realm of Lingbo microstep!

Third, before reaching the strength of the spirit level, he can move in the air with the help of the wind footwork, similar to the spirit level powerhouse flying in the air, which is also called the wind travel realm!

The fourth level, that is, the realm that Du Long has reached now, perceives the fluctuations of the wind, integrates himself into the fluctuations of the wind, people move with the wind, and the wind helps people walk, so it is called the realm of wind and waves!

All along, Du Long has been in the realm of turmoil, although the body method is constantly improving, but he has always been in this realm, and now he has reached the peak of this turmoil realm, and then it is the fifth level of the wind footwork to break the empty realm!

According to Ring Spirit Ling'er, as long as Du Long can break through the Void Breaking Line, there will be only a handful of immortal cultivators in the entire Immortal Realm who want to surpass him in speed!

Because of this, Du Long was particularly yearning for the realm of breaking the void line of the fifth level of the Fengxing footwork, but unfortunately, the spirit of the ring only told him the oral decision of cultivation, but he could not explain the principle of breaking the void line clearly.

According to her, breaking through the void is related to the mystery of space, if you want to break through this realm, you must strive to comprehend the body of space, this mystery is very special, it is also many six-star level immortal cultivators, if you want to break through to reach the seven-star level, you must understand the mystery of heaven and earth.

It is precisely because of this space mystery that the seven-star powerhouse has the ability to travel through space!

For this reason, Du Long once asked Ring Ling Ling'er if as long as he broke through to the seven-star level strength, he would definitely be able to break through the fifth realm of Fengxing footwork!

In this regard, Ring Spirit Ling'er's answer was very simple, that is, breaking through the seven-star level strength, at most, it would only allow the immortal cultivator to have the ability to travel through space, but he might not be able to comprehend the wonderful body method of breaking through the sky!

She also said that the Xuantian Decisive Exercise Technique that Du Long cultivated was different from the ordinary Immortal Cultivation Technique, he did not need to break through to reach the seven-star level strength, as long as the soul breakthrough reached the Fourfold Heaven Realm, and then the Xuantian Decisive Exercise Cultivation reached the fourth layer, that is, from the beginning of chaos to the Yin and Yang realm, and broke through to the great realm of the beginning of Qiankun, he would be able to have the strength equivalent to the seven-star level!

Once he breaks through from the beginning of chaos to the great realm of Qiankun Shidian, his comprehension of the mysteries of space is definitely far beyond that of ordinary immortal cultivators, and when the time comes, it will be relatively easy to break through to reach the fifth level of the Fengxing footwork!

On the top of the nameless peak, the cyan figure blended into the whistling mountain wind, and the figure flashed back and forth like a ghost, and after a long time, the figure that was originally moving at high speed condensed into one, revealing Du Long's face that had been slightly sweaty.

In order to better cultivate, he, the master of Qinglang Cave Heaven, used the power of Cave Heaven to restrain his body, forming an existence similar to a strong gravitational force, so that cultivating Fengxing Footwork would naturally get twice the result with half the effort!

Otherwise, not to mention that he is so good at cultivating footwork, even if he continues to practice for ten days and half a month, he may not sweat a drop!

Call!

With a long exhale, Du Long shook his head a little helplessly and muttered to himself: "Alas! The fifth level of the Fengxing footwork is the realm of breaking through the void, I don't know when and what month will it take to break through this realm?!

Although after breaking through to the realm of the Beginning of the Universe, you can sense the existence of the mysteries of the space more clearly, it doesn't mean that you can't comprehend the mysteries of the cultivation space now!'

'Oh?!' Du Long's eyes lit up and said, "But why can't I sense the existence of the mysterious space?!"

"If you want to be fast, you can't reach it, the mysteries of space are called among the countless mysteries between heaven and earth, relatively top-level existences, naturally it is not so easy to perceive the existence, but as you who have a sword-shaped primordial god, you don't have to be presumptuous, the mysteries of space should not be difficult to sense for you!"

Nodding, Du Long's originally depressed state of mind was relieved, but he no longer dwelled on this issue, shook his head, and then showed a smile on his face again: "Hehe!

As the words fell, I saw that his whole person turned into a cyan streamer and flew away from the nameless peak, and then disappeared abruptly, and when he reappeared, he had already appeared in the main hall of the Dantang Hall of Qinglang Palace!
