，

The Ling family was as quiet as ever, and this quietness made the people of the town feel suffocated by the storm. Their eyes couldn't help but focus on the Ling family, but they found that they were much more low-key than before.

Of course, this was a good thing for Xu Feng, as it gave him enough time to cultivate the mystical skills he had obtained in the cave.

Seven kills and slashes!Ground grade intermediate sword skills!Cast with the fury and domineering that Xuanpin Xuan Technique does not have, sword skills are sharp and tricky, the sword has seven moves, the moves are furious, the seven moves are superimposed, and there is a terrifying earth-shattering horror!

Xu Feng has been immersed in cultivating this set of mystical techniques these days, and as peculiar as the sealing cold technique is, as an earth-grade mystical technique, Xu Feng can also cultivate and perform it. Of course, Xu Feng couldn't fully use this set of Xuan skills, and all he could do was three of them. After three moves, the strength is exhausted, and there is no strength to perform the fourth move.

However, for Xu Feng, he was extremely excited to be able to perform three moves. Other mystical masters, who can use the earthly grade mystical technique when he is a powerful mystic?!And what Xu Feng also didn't know was that the speed at which he cultivated the mystical technique was very fast, which was simply incredible. In less than a week, Xu Feng was able to cultivate the earth-grade mystical technique to a certain level. This is something that even a martial artist at the level of the Spirit Entering cannot do.

Just after the skillful seven kills, Xu Feng's mind was finally put on improving his strength. Jiupin's strength, although he is considered a sideways figure in the town, but because he killed Ling Bo, Jiupin's strength is not enough to ensure his safety. What's more, although Xu Feng is confident that he will defeat Ye Hu now, after his strength reaches another level, there will be no suspense about defeating Ye Hu.

"It seems that it's time to try the method that Uncle Ye said, if you can integrate the aura into the qi. Ten grades can be easily achieved!"

Thinking of this, Xu Feng crossed his legs and began to cultivate the Dao Xuan Sutra. Dao Xuan Jing, as a treasure of Huaxia, Xu Feng can feel its peculiarity, this set of exercises is far stronger than other Xuan techniques. Judging from Xu Feng's state, this set of exercises is completely the practice of double cultivation of art and Xuan.

Just in the first volume, Xu Feng felt the breadth and profundity in it, and every time he cultivated, he had a new layer of comprehension. Let Xu Feng's use of qi rise to a few levels!

Of course, this is not what surprised Xu Feng the most. And what surprised Xu Feng was that with his slow cultivation, the second volume faintly had a tendency to open. Remembering that when the first volume was opened, Xu Feng got the healing technique Pure Xuanju, and Xu Feng thought that if the second volume was opened, there would definitely be other Huaxia exercises.

Compared with the mystical techniques of this world, Xu Feng is more willing to practice Huaxia exercises, and in Xu Feng's heart, Huaxia's things are always better than others. This mentality is like your own mother is always better than other people's mothers!

Xu Feng, who was immersed in the cultivation of the Dao Xuan Sutra, tried hard to find the aura hidden in his body. However, what disappointed Xu Feng was that no matter how much he searched, he couldn't find the so-called aura.

Xu Feng didn't expect to find the aura at once, he was extremely patient and repeatedly groped in his body.

After searching again and again, and failing again and again, Xu Feng frowned slightly, stopped cultivating the Dao Xuan Sutra, and the seal knot in his hand began to form the handprint of the Han Sealing Technique.

Since the aura can't be found under normal circumstances, it can only be with the help of the cold sealing technique. Casting the Sealing Technique requires aura, and Xu Feng wants to see where these auras are gushing out.

At the same time as Xu Feng's seal knotted up, Xu Feng's mind merged into his body, and at the same time as the energy poured into his arm, Xu Feng felt that a cool breath in his mind also poured into his arm.

This feeling made Xu Feng's heart happy, and his mind chased away, and at the same time, the seal knot in his hand was knotted more quickly.

When Xu Feng's handprints were getting faster and faster, the cool air flow gushing out of his mind gradually increased. This allowed Xu Feng to capture where this air flow was gushing out!

To Xu Feng's surprise, this air flow actually gushed out from the lotus bud that had never bloomed.

"The aura in the purple thunder?" Xu Feng was stunned, thinking to himself that it was no wonder that he couldn't find it after looking for so long. It's just that Xu Feng was surprised, why did the spiritual energy that was devoured by every cultivation of the Dao Xuan Sutra pour into the purple thunder, couldn't his body contain the spiritual energy?

Of course, Xu Feng didn't know that compared to his body, the aura's resistance to purple thunder was far smaller, and it was even said that it was not resistant at all. This is also the reason why these spiritual energy will pour into the purple thunder.

Knowing that these spiritual qi were in the purple thunder, Xu Feng dispersed the cold sealing technique he had condensed, and his brows furrowed slightly. It is quite difficult to infuse the aura into the qi from the purple thunder.

Xu Feng thought for a long time, and couldn't help but imagine if he could integrate the purple thunder into the qi, if the purple thunder could be integrated into the qi, then the aura contained in him could naturally be integrated into it.

Thinking of this, Xu Feng began to drive. Driven by Xu Feng, the purple thunder began to rotate, and a purple thunder silk dispersed from the purple thunder and spread towards the qi.

Controlling the purple thunder and qi continued to approach, Xu Feng held his breath, and paid attention to the two.

"Boom ......"

When the two merged, a thunderous roar sounded, and the strength seemed to meet a wild beast, frantically getting out of the way, not daring to make contact with the purple thunder. Xu Feng felt a huge force hit him from his body under the frantic movement of his strength, and the severe pain made his face pale.

Xu Feng tried his best to endure the pain, his heart was ruthless, and he once again pulled his strength and purple thunder together. The same as just now, the strength still didn't dare to touch the purple thunder, and the crazy retreat, the power brought up hit Xu Feng, and a sharp pain emerged from the inside out.

Stabilizing the churning qi and blood in his heart, Xu Feng took a deep breath, looking at the trace of purple thunder, with the state of his strength just now, he wanted to integrate the purple thunder into it, and there was little hope.

The temptation of stepping into the tenth grade made Xu Feng unwilling to give up so lightly, and after thinking about it, he suddenly began to control the purple thunder scattered, and from it again, he pulled out a trace of almost invisible purple thunder.

Pulling out such a trace of purple thunder, Xu Feng once again drove the qi in his body, condensed all the qi in his body, and then slowly approached this trace of purple thunder, which was almost invisible.

Xu Feng held his breath, gathering all the qi in his body and a trace of purple thunder contact, and the qi was still extremely repulsive. It's just that it may be because the purple thunder is too small, and the repulsion of the qi is much smaller than just now.

Xu Feng used all his strength to force the past, and under this crazy pressure, these forces that resisted the purple thunder finally dared to approach the purple thunder with the help of the terror of the number.

"Boom ......"

When the qi completely wrapped the purple thunder, the purple thunder also broke out with a roar, and the original purple thunder suddenly exploded, from which a stream of thunder and lightning and aura impact qi were differentiated, and then under the dense qi wrapping, they were integrated into the qi without impact qi wrapping.

This scene made Xu Feng stunned, because the purple thunder just now actually differentiated the green rock thunder that Xu Feng devoured back then, and these green rock thunder were also integrated into Xu Feng's strength. Xu Feng could feel that because of the differentiation and fusion of this trace of purple thunder, his strength had increased a lot, and at the same time, there was a flash of thunder in his strength.

This abnormal change in strength made Xu Feng frown, but seeing that it didn't hurt him, he didn't think too much about it. began to pull away the next trace of purple thunder.

With the first trace of success, the subsequent devouring is undoubtedly much simpler. Under the devouring of tiny purple thunder, Xu Feng's strength grew extremely considerably, and under this growth, the bottleneck of the nine grades began to be impacted by the strength.

After devouring a few traces of purple thunder, he finally broke through the bottleneck of the ninth grade in one fell swoop and reached the level of the tenth grade.

And when he reached the tenth-grade level, Xu Feng's qi was even more thunderous, with an extremely strong green rock and thunder aura. Compared with the past, Xu Feng's strength had a fury that only Heaven and Earth Xuan Thunder had.

Xu Feng was a little puzzled that the purple thunder only differentiated the green rock thunder, and originally thought that since the green rock thunder could be differentiated, it would definitely be able to differentiate the black thunder. But the black thunder was nowhere to be seen! This made Xu Feng guess, could it be that the purple thunder could only be differentiated into the devouring heaven and earth Xuan Thunder? If it wasn't the thunder of the Xuan Thunder, it couldn't be differentiated?

And the fact is just as Xu Feng thought, Xuan Lei is condensed by heaven and earth, and purple thunder can be differentiated, but like black thunder, it is in the body of a spirit beast, and it can't be compared with heaven and earth Xuan Lei at all, even if it is sometimes stronger than some heaven and earth Xuan Lei.

After fusing a few purple thunders again, the strength could no longer merge with a trace of purple thunder. At this time, Xu Feng's strength actually jumped to the middle level of the tenth grade, and even hit the peak level.

This situation made Xu Feng stunned, and no one could believe that the fusion of purple thunder could be so terrifying.

The most important thing is that the aura and green rock thunder possessed in Xu Feng's qi power made his qi no longer an ordinary qi power, and his qi power was completely changed.

Xu Feng punched at the void, he could even hear the thunderous sound in his fist, and the violent aura was far stronger than that of ordinary Xuan.

With the power of a lightning attack?!

Xu Feng felt that his head was not enough, and the power of such a mutation increased his attack power by several times. Every punch Xu Feng throws is equivalent to having the power of the green rock thunder!

I exhaled lightly and felt the surging power in my body. Xu Feng really wanted to find a ten-rank mystic to fight and see how terrifying his mutated strength was. Xu Feng faintly felt that this kind of strength was not something that a ten-rank mystic person could resist at all.
