Even so, Tian Xu still told Ziyan that now that her aura could be released more effectively, she could now consider using the sword qi in Ling Xiao's sword technique. As for how to release the sword qi and how to make the sword qi more powerful, she needs to figure out how to do it herself.

Tian Xu's custom-made spirit sword for Ziyan had not yet been completed, and she could only use that short stick to practice. After all, this short stick is not a real long sword, and Ziyan always has some plausible feeling when using it. Moreover, the ability of the short stick to transmit spiritual energy is insufficient, and it cannot exert the full power of Ling Xiao's sword technique, and it is not easy to feel the existence of sword qi. Tian Xu took out his spirit knife and let her try it. Ziyan gave it to him after trying it, and said, "This knife conducts spiritual energy much stronger than my short stick, but although the knife and sword are similar, the characteristics are completely different. On this spirit knife, the difference is even more obvious, and it is too awkward to use. ”

Tian Xu also understood the difference between the two, but he really didn't have a suitable long sword in his hand to use it for Ziyan. Suddenly, he had an idea, and he thought of the spirit rhino finger that he had used as a thin one. The Lingxi Finger was originally a Tibetan antelope horn, with a slender shape, and the root was about the same thickness as the hilt of the sword, up to 8 or 90 centimeters, and the shape was not much different from a long sword. This spirit rhino finger is extremely convenient for the transmission and control of aura, and is the best choice for practicing swordsmanship.

Tian Xu took out the remaining four spirit fingers and asked Ziyan to choose one to use as a long sword. Purple Smoke finally chose the hardest one. The harder this spiritual rhino finger is, the worse it will work on the aura, but if it is too soft, it will deform with the movement, and if it is soft, it will be more like a whip, which is really not easy to use.

The two of them didn't know that Ziyan had chosen this spirit rhino finger of the worst quality, but she had taken a shortcut to cultivation by mistake.

You must know that when you practice with weapons that have poor control of Reiki, it will be easier for you to realize your shortcomings in Reiki control, and strengthen and improve them in a targeted manner, which is very beneficial to your cultivation. If you practice with a spirit weapon with better control, the progress will be rapid, but many flaws will be inadvertently retained, leaving hidden dangers for future cultivation.

In this way, if you don't use spirit weapons, wouldn't it be better to practice with ordinary weapons? The advantage of the spirit soldier is that it can allow the practitioner to experience the feeling of releasing the aura and controlling it outside the body in the shortest possible time, which is still very beneficial to cultivation. It's a matter of degree.

However, for ordinary cultivators, there was basically no point in discussing this issue. Because spirit weapons are extremely rare, not just anyone can have them. Even with a sect like the Kunlun Sect, which is second to none in the cultivation world, the number of spirit soldiers is only a few. is like Ziyan, although she is the only daughter of the head, she can't mix it up in the qi gathering stage. As for some small and medium-sized sects, most of them don't even have one. Even if you don't have one, you don't dare to show it easily, for fear that someone will come to grab it.

The thin knife that Tian Xu snatched from Wen Yihe could actually be regarded as a low-level spirit soldier. It's just that the thin knife is more conducive to the concealment of aura and murderous aura, and the control of aura is only slightly stronger than ordinary weapons.

Like Tian Xu, spirit soldiers, elixirs, pills, and space containers can be taken out at will, and no one can take them out casually, they are really outliers in the cultivation world, and there have not been one or two in thousands of years.

Ziyan held the spirit rhino finger and stood on the big stone that Tian Xu had moved for her, recalling the points her father had taught, and trying to release the spiritual energy through sword moves for the first time. This matter itself was not too difficult, and Cheng Yuan, the ninth senior brother of her own sect, had used it when he was gathering qi at the ninth order. It's just that the distance of the aura is not far away, and the power is limited, so it basically can't pose a threat to the cultivators of the Ning Dan Realm.

According to the essentials passed on by his father, Ziyan opened the meridians through which the spiritual energy was to flow, and finally when he waved his hand to make a move, the spiritual energy in his body rushed out along the path of the meridians that had been opened in advance, condensed and formed in the spiritual rhino fingers in his hand, and finally issued with the command of the mind. An arc-shaped translucent aura blade bloomed with a faint brilliance from the tip of the Spirit Rhino Finger, and flew quickly into the distance.

The length of this sword qi is about one and a half meters, and the color is very light, and it is difficult to find it without looking carefully in the sunlight. The sword qi swept into a big tree ten meters away, and was shaken away by the big tree and disappeared. Only a shallow mark was left on the trunk.

Ziyan pursed his lips, quite dissatisfied with the power of this blow, even if he was an ordinary person, he could only get a skin wound when he took this blow, which was really useless and useless.

Ziyan knows where the problem lies, one is that his aura is insufficient, and when it is sent out, it is limited by the width of the meridians, and the aura emitted at one time only accounts for less than one percent of his own aura, so of course the power will not be great.

The second is that the degree of condensation of the sword qi emitted is not enough, it is one and a half meters long and nearly one centimeter thick, such a large force area, the force is weak, and the aura is greatly diluted. If the thickness of the blade can be compressed to less than one millimeter, and the width can be reduced to a fraction of the size, the density of the aura will increase by dozens of times, and the power will of course be much greater.

The problem of the total amount of aura and the width of the meridians in Ziyan's own body was quite difficult to solve, so she decided to put this problem aside first, and strive to solve the problem of the condensation of the aura blade first.

In this regard, Tian Xu had already given her enough hints in the previous days. At that time, when Tian Xu taught her to use aura to clean up the dirt on her body, she had already preliminarily mastered the method of compressing aura, and at this time, with the help of the spirit rhino finger, it was not too difficult for her to do it.

It took Purple Smoke less than a day to successfully compress the sword qi to a thickness of about two millimeters, and the length was also compressed from the original one and a half meters to a little more than half a meter, and the density of the spiritual energy in the sword qi increased by more than ten times while the total amount of spiritual energy remained unchanged.

The sword aura she emitted at this time was much darker than at the beginning, and when she hit the target within five meters, she could already cut through trees half a foot thick, and she initially had the ability to use it as an attack weapon. Beyond five meters, her control over the aura will be greatly weakened, and the speed at which the sword qi will dissipate will accelerate, and she will soon lose her cohesion and become an ownerless aura that will return to nature.

At the end of the day, Ziyan was very tired. The aura in her body is limited, and she has to do her best to release as much aura as possible every time in order to condense the sword qi. You must know that the aura in a cultivator's body has become an indispensable part of the body, and when the loss of aura exceeds one-third of the total amount, one will feel fatigued.
