The core disciples of the Yuntian Sect can receive a Zhuji Dan from the sect when they cultivate to the twelfth level of Qi refining, and this provision makes the other four major sects in the five major sects of Jianzhou envious, because the rest of the sects, even the core disciples, have to go through a battle before they can obtain the Zhuji Dan.

Zhuji Dan is very precious, not because the elixir for refining Zhuji Dan is precious and scarce, but because there are countless Qi refining disciples in the Immortal Cultivation Realm, and no amount of Zhuji Dan can meet this huge base, but Yuntian Sect is a sect famous for alchemy, and Zhuji Dan is naturally much more than other sects.

Looking at the Zhuji Dan in his hand, which was the size of a dragon's eye and exuded a rich fragrance, Xu Qing was slightly excited, as long as he took this pill, he might be able to successfully enter the foundation building period. There is a difference between the foundation building period and the qi refining period, and the great consummation of qi refining is only one step away from entering the foundation building period, but in front of the strong people in the foundation building period, the great consummation of qi refining is only a child of seven or eight years old, and he is completely vulnerable.

Xu Qing was not in a hurry to take the Zhuji Dan, and the foundation building was to condition the physical body so that the body would be more in line with the requirements of cultivation and more in line with heaven and earth. Generally speaking, the better the qualification of the spiritual root, the less medicinal power is consumed, and the worse the qualification, the more medicinal power is consumed.

Xu Qing was very aware of his qualifications, he knew that it would be difficult for him to succeed in building a foundation with a Zhuji Dan, and even if he took the Zhuji Dan, he would eventually fall short, so he wanted to wait until he found the Zhuji Dan to be more sure before building the foundation.

Building the foundation means building the foundation of the immortal path, the Qi refining period is a very special realm, the monks of this realm are very weak and fragile compared to the monks of other realms, and the monks of the Qi refining period are as small as ants in the eyes of those high-level monks.

But this realm is a very important realm, although almost no one cares about its importance anymore. Thousands of tall buildings rise from the ground, let it be thousands of feet high, if there is no solid foundation, it will eventually collapse. The Qi refining period is the foundation of a higher realm, only with a solid foundation can you achieve brilliance in the future, if you only count on Jindan Yuanying, Xu Qingzi doesn't have to care, but he doesn't want himself to stop there, he has higher goals, higher expectations.

The use of pills to improve the power is natural and fast, but the disadvantages are very obvious, the refining power is not condensed from the heaven and earth after all, so it is mixed and impure.

Xu Qing's task in the next few days is very simple, to regulate his body well, condense the mana in his body, make it more pure and clean, and eliminate hidden dangers in his body.

In Yunmeng Mountain, a remote mountain, it is very barren, there is almost no vegetation, only the chirping of a few passing wild birds occasionally adds some vitality to this place.

Xu Qing stood on the top of the mountain and carefully inspected the jade slip in his hand, carefully experiencing every word and sentence in it, making it deeply in his mind.

The jade slip records the five elements of thunder resistance, after learning it, you can summon five kinds of divine thunder to resist the enemy, and it is wonderful, and its words are beautiful, which makes Xu Qing admire.

The Five Elements Thunder Technique is indeed a wonderful method, which can summon five kinds of divine thunder out of thin air, namely Gengjin Divine Thunder, Yimu Divine Thunder, Kwai Water Divine Thunder, Binghuo Divine Thunder, and Wutu Divine Thunder, which belong to the Five Elements.

Although this method is wonderful, few people practice it except for the Lei Linggen, one is because it consumes a lot of mana to perform this technique, and the other is because although this technique is extremely powerful, it is difficult to give the other party a fatal blow if the cultivation is the same, so this technique seems to be a bit chicken.

But Xu Qing didn't care about this, he used the pill to improve his power and made the mana in his body impure, if he wanted to condense the mana in his body, he could only continue to consume it, and then draw spiritual power from heaven and earth to refine, and the cycle would go on and on, so that it could be effective.

Cultivating the Five Elements Thunder Technique consumes a huge amount of mana, so it is his only choice, and Xu Qing's cultivation is very miraculous, and his mana depth is far beyond that of a monk of the same level, so the power exerted by the Five Elements Thunder Resisting Technique in his hands will also be incomparable to ordinary people, and it can pose a threat to the same level.

Thunder is born between heaven and earth, and it is the wrath of heaven, how can ordinary people master it? When cultivating the Five Elements Thunder Technique, you need to be extremely careful, and if you are not careful, the divine thunder may backlash. Because of Xu Qing's exercises, his spiritual sense is far beyond that of the same level, so his control is stronger than that of the same level, but he is also extremely cautious at this moment, and he does not dare to be distracted in the slightest.

Xu Qingjing stood on the top of the mountain, closed his eyes and contemplated, as if he was in harmony with heaven and earth, and in harmony with heaven and earth, at this moment, he was constantly evolving the Five Elements Thunder Technique in his mind, evolving again and again, not letting go of a detail.

Suddenly, Xu Qing opened his eyes, and his divine light appeared, as if there was thunder leaking from it. He raised his right hand, stretched out his index finger, and drew a virtual line in front of him, and runes with incomprehensible meanings were generated on Xu Qing's fingertips, exuding a faint golden light. Although Xu Qing's technique was still a little jerky, his gestures were uninterrupted, and golden runes loomed in front of his predecessor.

It's just that the rune suddenly disappeared without warning, which made Xu Qing stunned for a while, and he carefully thought about the mistakes made in the process of casting the Five Elements Thunder Technique, and then corrected it and recast it.

Xu Qing has been practicing for five hours, because of the first cultivation, he always makes mistakes of one kind or another, but Xu Qing is not discouraged, corrects again and again, starts again and again, and sits down when his mana is exhausted.

Three hours later, as runes were generated under his index finger, Xu Qing felt the mana in his body pouring into his right hand like a torrent, and then vented out from his index finger, turning into mysterious runes, and the speed of its loss made him frightened.

Despite this, Xu Qing still kept gessing, but when there was still the last rune left, his gesture paused, and the rune in front of him flickered a few times and disappeared completely, while Xu Qing's face at this time appeared a bright red, and instantly turned pale.

Xu Qing took a healing elixir and sat in place to breathe for a stick of incense, and his face gradually returned to ruddy, but he still had palpitations. Casting the Five Elements Thunder Resisting Technique consumes a lot of mana, and he has already been mentally prepared, but he didn't expect that with his Qi refining Twelve Layer Perfection Realm, his mana would not be able to support the spell until it was completed.

Just now, Xu Qing wanted to use Gengjin Shenlei for his own use, but before he could finish casting his mana, he was consumed, because he was not yet proficient, and when Xu Qing tried to forcibly terminate the spell, he mishandled it, suffered a little backlash, and was injured a little. The only thing worth being happy about is that when he performed the Five Elements Thunder Technique just now, there was no mistake at all, if the mana was enough, Xu Qing was confident that he would be able to successfully draw out the Gengjin Divine Thunder.

At this moment, there was hardly a trace of spiritual power in Xu Qing's body, he sat quietly on the top of the mountain to breathe, and the majestic spiritual power quickly surged towards him with him as the center.

Xu Qing only knew that few people practiced the Five Elements Thunder Resisting Technique, but what he didn't know was that except for those Thunder Spirit Root Cultivators, the monks generally only practiced the Five Elements Thunder Resisting Technique when they reached the foundation building period. The mana of ordinary monks during the Qi refining period is simply not enough to perform the Five Elements Thunder Guarding Technique, and in addition, the spiritual sense during the Qi refining period is too weak and the control is not enough, it is difficult to control the divine thunder, and it is easy to be counterattacked.

If Xu Qing knew this, he might be even more curious about the exercises he cultivated, but the effort was always proportional to the return, and the pain Xu Qing endured when he cultivated the Five Spirits was far greater than that of others, so it was expected that he would be able to do this when he performed the Five Elements Thunder Technique.

Although the cultivation of the Five Elements Thunder Resisting Technique failed this time, Xu Qing was not discouraged, he was originally trying to condense the mana in his body, and the Five Elements Thunder Resisting Technique could help him achieve his goal very well. Moreover, with the continuous accumulation of time and the continuous condensation of mana in his body, Xu Qing was confident that he could successfully perform the Five Elements Thunder Resisting Technique before building the foundation.
