Yan Xu had a separate small courtyard in the residence of Master Elder Lan Yu, and there was a ban arranged by Lan Yu himself, except for Yan Xu, only Lan Yu could enter and exit freely, so Yan Xu could retreat with peace of mind.

It's just that although he knows the horror of martial arts cultivation to the depths from his body, Yan Xu's background in this life is not good, and the surrounding area of the village is not a deep mountain and old forest, so in the absence of nourishment, it is not a good choice to choose martial arts entry, so at first Yan Xu only used martial arts as a means to strengthen his body, and he did not practice any weapons.

But now he is only at the beginning of the manifestation realm, and he can only project the natal spirit and attach it to the weapon, and only when he reaches the realm of the imperial spirit can he attack with a flying sword.

Therefore, Yan Xu has been very distressed about how to increase his strength in a short period of time.

In order not to waste time, Yan Xu could only choose a swordsmanship from his memory to practice, but this swordsmanship is quite famous, called the Yue Nu Swordsmanship.

Don't look at the name as a bit girly, but in fact this is a fairly old swordsmanship, and it is legendary.

The Yue Nu swordsmanship first came out of the Spring and Autumn Period and the Warring States Period, and it was a woman who learned a swordsmanship from a psychic white ape who danced a sword, so the sword walked lightly, and there were movements that imitated apes, which were in line with Yan Xu's setting for himself, and he was a genius boy who was good at imitating animals to practice fists and feet.

Moreover, the forging process in the Warring States period was limited, and the sword body was not long, which was suitable for short swords, so it was selected by Yan Xu.

In addition to practicing swordsmanship, Yan Xu also worked the Cold Water Sword, because of the lack of phantom spirits, although the quality of this sword is good, the power that can be stimulated is always limited, and it can only be used as an ordinary spiritual weapon, so Yan Xu intends to make good use of some of the activated power.

It looked bluffing to inspire a sword ray more than a foot long before, but the sword light was scattered but not condensed, and most of the power was wasted, so Yan Xu was busy condensing the sword light now.

In terms of condensing the sword light, Yan Xu didn't even need to ask Lan Yu, in his memory, the body had refined many magic weapons, and the methods were almost the same, Yan Xu didn't think that the ability of the body would be worse than Lan Yu, so he took himself as the foundation, took the little jumping frog as his own primordial god, and used the cold water sword as a magic treasure, so he refined it.

The little jumping frog has three characteristics: Yuan Spirit, Living Soul, and Machine Spirit, and the Cold Water Sword refined from the wings and bones of the Cold Water Sparrow also has these three characteristics, after all, the Cold Water Sparrow belongs to the living being, and the sword body made of bones belongs to the Machine Spirit, and because of the characteristics of the Cold Water Finch, the cold water with extremely cold attributes is automatically condensed inside the hollow bones, which belongs to the Yuan Spirit, which is completely in line with Yan Xu's attributes.

And maybe the spiritual cultivators would think that without the corresponding phantom spirit, they would not be able to activate the true power of the spirit treasure, but for Yan Xu, it only needed to be completely refined.

Therefore, Yan Xu drove the little jumping frog to swim in the cold water of the hollow part of the cold water sword, and at the same time kept swallowing the cold water, refining this cold water sword from the inside out.

Although the process is slow, the effect is still there, so Yan Xu can also calm down.

Yan Xu indulges in sword refining every day, but Lan Yu is a little strange, after all, he has already told him that he will upgrade in the next test, and asked him to improve his strength as soon as possible, but why didn't he come to ask for advice?

In fact, Lan Yu had already been prepared, and if he wanted to improve his strength in the short term, he couldn't rely on the natal spirit, after all, the natal spirit was in a hurry, and he needed to cultivate step by step in case something went wrong.

As for martial arts, for their kind of spiritual cultivators, martial arts are only auxiliary, and martial arts require perennial practice, and practicing martial arts at the beginning will drag down the cultivation realm of spiritual cultivation, and the gains outweigh the losses.

Therefore, Lan Yu originally planned to mention Yan Xu to work the Cold Water Sword, because it would also be of great benefit to his natal spirit, otherwise she would not have given away this sword easily.

But I didn't expect to wait left and right, but I didn't see Yan Xu coming, so Lan Yu was a little angry, and took the initiative to find Yan Xu, but when she saw the scene of him refining the Cold Water Sword, she was suddenly shocked, and when she took a closer look, she breathed a sigh of relief.

This spiritual treasure is not a spiritual weapon, and a spiritual weapon with only some psychic attributes only needs to be rendered with its own spiritual energy every day, which is the kung fu of the water mill.

But Lingbao is deeply spiritual, and it will backfire without a unique refining secret method, so she was shocked when she saw Yan Xu refining the Cold Water Sword just now, but after a closer look, she found that Yan Xu had actually figured out the method of refining alone, how could this not surprise her.

When Yan Xu finished his work, Lan Yu hurriedly stepped forward to check it, and found that although Yan Xu's method of refining the spirit treasure was too simple, the effect was similar to the secret method of the sect's inheritance, but it did not have the ability to promote, after all, this was a method that Yan Xu had figured out by relying on his own natal spirit attribute to be completely consistent with the spirit treasure, unless the other party had the same attributes and the same spirit treasure as Yan Xu, otherwise it was only suitable for him personally.

Lan Yu didn't care about this, in fact, because of the uncontrollable and diverse spirits, there were almost no exactly the same cultivation methods, just like the cultivation methods of a transcendent and holy grandmaster's spiritual cultivation could not make the spiritual cultivation of another spiritual system reach the top level, sometimes it was a good thing to change and innovate.

It's just that this kind of change and innovation will generally only be made after the spiritual cultivation has been introduced and has a considerable foundation accumulation, and even so, it is only a little adjustment and modification in the main body of the cultivation, and you don't dare to make drastic moves, after all, don't think that spiritual cultivation has not gone mad

However, Yan Xu is an exception, after all, there are too many places he can learn from, even if Lan Yu only finds some flaws from it after careful inquiry, but the main route is correct, and there is no need for major modifications at all.

And because this is completely a secret method tailored for himself by Yan Xu, the efficiency of cultivation is not comparable to that of general exercises, that is to say, the spirit gathering technique touted by Lan Yu now only has some reference effect for Yan Xu, which makes Lan Yu also have an understanding of the genius of his own apprentice.

Whether Yan Xu is a genius or not, I'm afraid even Yan Xu himself can't say, Qi Ling's acquisition of a top-grade natal spirit can only be said to be a good fate, and his cultivation also draws on the memories and experiences of many ontologies, what he has paid, I'm afraid even Yan Xu himself can't say clearly.

But for Lan Yu, Yan Xu is a genius, and he is still a genius that she didn't expect.

If it is an ordinary disciple, as a master, he needs to watch and teach him hand in hand, for fear that the disciple will make a mistake or be slack.

But Yan Xu is different, although he is young, he is already very self-disciplined, he doesn't need her supervision for daily practice, and he has a high level of understanding, and he can often draw inferences from one another, even with Lan Yu's temperament, he doesn't feel much trouble accepting such an apprentice.

However, finding out the method of refining the spiritual treasure and using it to practice alone was still much beyond Lan Yu's expectations, because this was beyond the scope of ordinary geniuses, so Lan Yu became more attentive to Yan Xu's teachings, and some of the content taught in the later period was also mixed with the teaching content on weekdays, which made Yan Xu's horizons more broadened and his understanding of the profession of spirituality more comprehensive.
