Almost five days have passed in the formation, and on the Seven Star Pier, Xu Yan can finally use all the moves of the Seven Star Sword Technique in one breath like a flowing stream, without completely consuming the qi accumulated in the qi mansion in his body, which is the best news for him, and the good news is not only that, he can now clearly feel that the qi in his body, after being watered by the aura of heaven and earth like spring rain, compared to when he first went up the mountain, it has been very significantly improved.

Sword cultivation in the world focuses on the conception and cultivation of qi in the body, which is completely different from martial cultivation in order to open more than 300 commonly used tricks on the body, sword cultivation focuses on qi cultivation, and martial cultivation is pure body refining.

In the past 20 days, Xu Yan not only practiced the seven-star sword technique created by the eighth generation sect master Yu Jingshi, but also used Song Yu's four-character sword technique perfectly, if there is any shortcoming, it is probably that when he used the sword technique of 'sudden' and 'rain', he was unable to use the power of the sword spirit in his hand, which made it difficult for the power of the sword move to exert such momentum as Zhou Xian. However, Xu Yan didn't feel discouraged about this, after all, it was not easy for him to be able to master the moves of the two sword techniques in such a short period of time.

However, if he had a chance to find the full version of the 'Seven Star Sword Technique' and obtain the method of using the power of the sword spirit early, then he would have a great future when he entered the Middle Three Realm.

Practicing the Seven Star Sword Technique again, Xu Yan was also a little short of breathing, but when he saw that the sword qi he used was able to match the seven sword marks on the sword cliff, he knew that his hardships in the past twenty days had not been in vain, and even this could make him not care, and compared with Zhao Bailian's gesture at the end, there was still a slight difference.

Xu Yan took a deep breath and put Fuyao into the scabbard on his back, although at this time, there was still a month or so before he had agreed with Zhao Bailian, but he didn't plan to continue to practice the sword in the formation, because when he heard that there was a red wind on this main peak, he wanted to find a chance to go up and have a look.

He took the storage bag that Zhao Bailian had prepared for him before and left this large array directly, and when his body passed through that layer of invisible light shield, he undoubtedly walked into the snowy expanse before.

A cold chill from the bottom of his heart came to his face, which made Xu Yan couldn't help but feel his legs tremble a little, but fortunately, his current physique, after opening the three most basic and important points of martial cultivation, was already several times stronger than sword cultivation of the same level.

Xu Yan tightened the storage bag on his body to ensure that it would not fall off for no reason on the way, causing him to lose dry food and water to fill his stomach and hunger, and then no longer hesitated and began to climb the mountain alone.

The snow on the mountain is like a thick layer of cotton wool wrapped around the mountain, and under the sun, it sometimes shines with dazzling light.

Every step Xu Yan took left a deep footprint in the snow, and it didn't take long for him to climb nearly a thousand meters along the peak.

If someone could see this scene from a distance in the air, they could see that in the endless white, the small black dot that looked very small had already left a long and neat row of footprints on it, however, rising to a distance of about a thousand meters was far from Xu Yan's goal, because at this height, he didn't even see the shadow of the red wind.

Almost another hour later, Xu Yan finally felt a trace of wind that was different from the natural blowing, this wind was more violent than the ordinary cold wind, and he could see that in this wind, mixed with wisps of gray mist, as if it was a gray wind.

When Xu Yan saw this gray wind, his frozen red face finally showed a relieved expression.

At this moment, he has a height difference of nearly three thousand meters from Qixingdun, if calculated according to the height of the entire mountain peak, it has probably reached more than 11,000 meters of the main peak, and the air here is so thin that ordinary people can't survive here at all, fortunately, Xu Yan, as a cultivator, as long as there is a place where the aura of heaven and earth exists, whether there is air or not, it has little impact on him. However, Xu Yan did not choose to stop here, but continued to climb to a high place, although the outermost red wind also had some effect on refining the body, but for him, after opening the main three points by himself, this level of red wind was no longer enough to make his physique improve greatly in a short period of time.

So, Xu Yan gritted his teeth and climbed up for almost a thousand meters before he felt a trace of pressure from this cold wind.

In his original heavenly domain, the red wind was divided into six levels, the first to fourth level of the red wind, can temper the martial arts created by himself, the first half of the 'earth-shaking' part is about six layers of cultivation (a total of ten layers), if according to the division of the five states continent, it is equivalent to the six grades of martial arts, as for the fifth and sixth levels of the red wind, at least the seventh and eighth grade realm of martial arts can withstand it, therefore, with the current strength of Xu Yan, when the wind power reaches about two levels, he stopped.

Compared to the outermost wisps of pale gray gray fog, the color of the wind in the second-level red wind area is undoubtedly much deeper, and here, the sunlight can no longer penetrate the wind layer, making the overall ambient tone look a little gloomy, just like the weather when it is about to rain.

However, it is clear that it is impossible to rain here, not to mention whether the rain can penetrate this wind layer, and even if it can, at this altitude, as soon as the rain lands, it may turn into ice in an instant.

Xu Yan chose a place that seemed to have a small snowdrift to stop, and then used the qi formed in his body with the improvement of the martial arts realm to release it, turning it into a stream of heat, melting all the snow on this small snowdrift, and sure enough, under the white snow, it was a protruding rock body.

Xu Yan untied all the belongings on his body, put them aside, and then sat down cross-legged on the rock.

To temper the body with the red wind, it is necessary to remove the invisible defenses condensed by the qi in the body, and let the red wind completely blow on the body, so as to create a thousand tempering effects on the body, and this process will undoubtedly be very painful. Xu Yan looked at the gray red wind blowing in the air, and his heart was extremely sad, because like this most basic refining process, he was far from thinking that he would have to feel it again in his lifetime, so it was not until he sat alone on this rock for almost two quarters of an hour that a trace of determination flashed in his eyes.

Xu Yan looked at this barren and abnormal mountain peak, exhaled a cold breath from his mouth, and finally his heart was ruthless, and he directly withdrew all the defenses on his body.

A gray mist mixed with dark gray swept through the sky.

Without Xu Yan, who was blessed by qi as a defense, after being blown by this gray mist on his shoulder, a large piece of flesh and blood was swept away in an instant.

A great pain came from his shoulder.

But before he could come back to his senses, countless pains flooded his body again.
