After thinking about it for a long time, Su Aotian felt that with his current situation, he really couldn't kill Sikong Dou. But they must not give up just like that, Sikong Dou is the same as Long Lingfei, although there is a world of difference in cultivation, but the arrogance in his bones is the same, and he also made a three-day contract for some reason, and I don't know if this is their own agreement, or the hunting rules of Twilight Akita Hunting, everyone is arrogant and domineering. Maybe in their hearts, these two-legged beasts are all hand-to-hand, and it is more fun to want to capture them, and it is not fun to kill them all at once.

Although the time of three days is extremely short, it can make a big difference if it is used well. Su Aotian decided to seize the time and take the opportunity to improve his strength. Since entering the Twilight Garden, except for the short period at the beginning, they have been struggling on the edge of life and death, and they don't know how time has passed, in fact, three years have passed. Thanks to the strange aura nourishment in the Twilight Garden, his cultivation has been greatly improved, but he really doesn't have time to calm down and sort out and refine it.

However, three years is really short for cultivation, and the improvement of cultivation is only relative, and it is impossible for him to break through from the Holy Rank to the Taixuan Realm in one fell swoop, at most, it is to consolidate the foundation of the sub-saint, and he can consider impacting the half-saint. But three days was by no means enough time for him to make a breakthrough successfully, so he could only accumulate a little and save a little to lay a good foundation for the breakthrough.

Therefore, it is impossible for the cultivation to increase significantly in these three days, and it will play a very small role in the improvement of one's own strength. In this case, if you want to make a big improvement, you can only use foreign objects, Su Aotian is thinking of refining weapons, to be precise, to refine the Heavenly Demon Qin.

After the Heavenly Measuring Ruler evolved into a holy weapon, it still stayed in the box behind the handle of the Heavenly Demon Piano when it had nothing to do, and it liked it very much. The Heavenly Demon Qin has also continued to bear the nourishment of the measuring scale, and the subtle progress is also very considerable under the accumulation of years.

During this period of time, although he was hunted and hunted by the elites of various ethnic groups, there were many who died in his hands, and these people were all wealthy, and there were two holy weapons. Although they didn't bring all their wealth and resources with them when they came to hunt this time, there were always some refining materials in everyone's storage equipment, because their magic weapons and other equipment might be damaged and needed to be repaired in time.

Therefore, among the trophies seized by Su Aotian, in addition to the holy weapon rune treasure pill equipment and so on, there is also a refining furnace, which is also a high-grade spiritual weapon. Generally speaking, the refining furnace is not too aggressive, but for immortal cultivators who are good at refining weapons, it is definitely an indispensable must-have for home travel.

There is no shortage of all kinds of talents among the elites of all races, and among the people who fell into Su Aotian's hands, there was a refining master, and his refining furnace was now in full use. Three days was not enough time for the Heavenly Demon Qin to have an advanced change, but in terms of the degree of improvement, it would definitely be much better than Su Aotian's own cultivation.

As soon as he said it, Su Aotian immediately laid out the spatial formation and hid himself. Since you want to open the furnace and refine the furnace, of course you can't be disturbed, and the prohibition is not safe, and you can directly enter the space. Because he didn't have the time to prepare before entering the Dusk Autumn Garden, Su Aotian couldn't arrange the teleportation array, otherwise he was in a dangerous situation now, and there was still a way out, and Wu Zhengming and the others would not die miserably here.

The space can only provide a secret place, and Su Aotian can't stay in it and never come out. Not to mention that when the scene is cleared, it is possible that the great power will detect it and force him out of the space, even if he hides from everyone, he can't be trapped here. Unable to find Yingsleeve, Su Aotian was in a hurry, and worried that she didn't know what she would be in a hurry.

Sikong Dou kept his promise, but also because he was full of confidence, and felt that Su Aotian was already pinching it in the palm of his hand, and he couldn't turn it over, so he only waited for three days to grab someone with a handle in his hand. In his heart, he also hoped that Su Aotian would be able to hold on for a long time, and that he would be more strict in hiding and absconding, so that he would not be discovered at once, and that the process of this hunt would be as long as possible.

He didn't lock on to Su Aotian, so he didn't notice that Su Aotian's aura suddenly disappeared without a trace. Otherwise, he will definitely come back to check suspiciously, and he will definitely be in a hurry to search for no results, don't think about spending the three days in peace.

In the space, Su Aotian first held his breath, roughly sorted out the progress over the years, and consciously benefited a lot, and then adjusted his mental state to the best, before taking out the refining furnace, pointing his fingers, and shooting into the fire and starting to heat up.

If you want to do a good job, you must first sharpen your tools, of course Su Aotian understands this truth, although the time is urgent, he did not rush to start work as soon as he came up, but did the basic work first. After everything was ready, he took out a pile of refining materials, and after screening and examining, he took out the suitable ones and put them into the refining furnace for burning and refining.

The function of the Heavenly Demon Qin is mysterious, it is a special magic weapon, there is no need to have too high requirements in terms of hardness, Su Aotian focused this refining on the effect of sonic attack. The original strings were made of animal tendons, and the original Jiao tendons of the psychic realm were the best materials for making strings, but unfortunately Su Aotian was seriously injured and dying, and Lian Qiongyu's life and death were uncertain, and the situation was very grim.

But now among the items he seized, there is such a thing, a very tough, about half a foot thick, with more than ten zhang of beast tendons, I don't know what kind of spirit beast, but from the size of the object, it must be a huge python, although it is not as precious as the psychic realm, it is also suitable.

Secondly, in terms of timbre resonance, this time we also have to put some effort into it, specifically to transform the body of the piano, eliminate the scattering of sound waves as much as possible, and concentrate it for feedback. Although the material does not deliberately require hardness, the stronger the better, after all, when Su Aotian plays, it is also infused with aura, and the stronger the aura that the Heavenly Demon Qin can withstand, the stronger the sonic power it transforms.

The material for the reinforcement of the body, Su Aotian chose a kind of jade. Unlike most jade, which is shiny and hard, this piece of jade does not have a pleasing brilliance, but it has a soft texture that can change its shape without the use of aura, just by pinching it with your hands. The softness is somewhat similar to dough, but it is much tougher and does not easily deform without overstrength.

In addition, he had chosen a smooth hide, so tough that with his divine powers, it was even difficult to tear it apart. In this way, the body of the Heavenly Demon Piano can be toughened while improving its strength, which not only ensures the compression resistance of the body, but also has enough elasticity and deformation when collecting the reflected sound waves, so as not to make the sound sharp and harsh. The melodious sound of the piano is more acceptable, and it is actively accepted, which is a great enhancement to the effect of confusing the soul.

After the materials were ready, Su Aotian controlled the change in temperature and put them in one by one. The consciousness precisely controls the heat, feels the subtle changes that occur between materials, discovers the strengths and weaknesses of various materials, and adds other materials to complement them according to the situation. After the materials were almost refined, he put in the Heavenly Demon Qin, melted the animal tendons, and replaced them with new strings; after the body was softened, he poured the jade solution into it, fused it with the original materials, and finally covered the inner and outer sides with animal skins, completely fused, and the whole refining process was completed.

The Heavenly Demon Qin slowly floated from the refining furnace, and the color of the body had completely changed due to the new jade. The animal skin is thin and transparent, as if a film is plated on the surface of the piano body, and the pale cyan jade brilliance floats from below, faintly like the flow of water waves, and the Heavenly Demon Qin presents a dreamlike sense of unreality, with a strange look, slightly fluttering, making people feel that inadvertently, it will disappear quietly and disappear into the unknown space.

Suddenly, Su Aotian's heart moved, and a feeling of joy floated in his heart, and the fresh and strange feeling made him stunned at first, and then he reacted after a while, this is the Heavenly Demon Qin, and the Heavenly Demon Qin is calling him!

Heavenly Demon Qin actually gave birth to spiritual wisdom, which was definitely something Su Aotian never expected, and after being stunned, he couldn't help but be overjoyed!

Since ancient times, artifacts have spirits, and only those gods that have seized the creation of heaven and earth, and collected the essence of the universe, and the refined instruments can have their own spiritual intelligence, which is the so-called instrument spirit, which can communicate with the winner and be harmonious until it becomes a part of itself, and the water is inseparable and inseparable. The artifacts discovered in the Chengtian Continent one after another have their own artifact spirits, and they are all believed to have fallen from the upper realm, so they are uniformly named as artifacts, such as Taiji strings, Haotian hammers, sun and moon divine blades, etc., all of them.

The origin of the measuring ruler is unknown, but Su Aotian can feel that its origin is huge, and it is not as simple as being too hard. Although Su Aotian was pleasantly surprised, he gradually took it for granted, and if he couldn't cultivate it for a long time, he would feel that something was wrong.

But the Heavenly Demon Qin is the product of the Chengtian Continent itself, and the Nine Evil Qin Demons are also natives of the Chengtian Continent, and they have never left the Chengtian Continent in their lives, until they fall, but they have not cultivated to the realm of distraction, and they have not yet reached the tribulation.

Its material is also an ordinary item produced by the Chengtian Continent, although it is a rare treasure in the Chengtian Continent, but in the spirit world, it is not as good as a steel drill for the martial artists to mine ore, and it has also evolved its own spiritual intelligence, which really makes Su Aotian overjoyed!

Heavenly Demon Qin emitted a vague sense, very dependent on himself, if Su Aotian and Luo Yingsleeve had a descendant, he should be able to feel that this kind of psychology was extremely similar to a baby's dependence on their parents. Luo Yingsleeve is very talented and amazing, it may be because of this reason, the two of them have not had children so far, of course, there are also reasons why the two of them get together less and leave more.
