During this period of rest, Wan Kai had been preparing to refine the spirit weapon, and at this time he was still a little nervous. The furnace was opened by him, and the scorching flames glowed pale gold. The refining furnace here is divided into three grades, the outermost nine are the first grade, the middle nine are the second grade, and the innermost nine are the third grade.

The spirit weapons refined by the different grades of the refining furnace are also different, and the cultivation of the refiners is also different. A person like Wan Kai can only use a first-grade Ding Furnace, his ability to control the fire vitality is limited, even a first-grade Ding Furnace needs to be controlled by all his might, and the slightest carelessness will definitely fail in refining the weapon.

The flames were burning, and the thick fire energy gushed out from the Ding furnace, making the Huoyuan Cave seem to be much hotter, in fact, the Huoyuan Cave was already very hot, Wan Kai, Liu Shi, and Mo Kongsheng were already naked before, so it would save trouble. Because under such high temperatures, there will be sweat flowing out, and if you are naked, you can rely on the heat to evaporate.

Yang Chen first threw in a piece of ice and iron separation stone, and the sword body refined from such iron and stone would be blue and shining. The name of the Blue Edge Sword is also derived from the iron stone used. Under the melting of the flame, the ice iron and stone quickly melted into molten iron, and the impurities in it turned into ashes in the process of smelting. The red molten iron is tumbling and flowing in the Ding furnace, which is Wan Kai's control of the fire vitality to make the molten iron repeatedly smelted in the Ding furnace, only in this way can the molten iron be the most pure.

After a while, the molten iron turned reddish, which was a sign that the ice iron had been successfully smelted. Bone essence powder, cloud blue wood, black shadow heavy water Wan Kai read out the names of the spiritual materials one by one, Liu Shi was in accordance with Wan Kai's prior arrangement to throw these spiritual materials into the Ding furnace one by one, and it is also particular about putting the spiritual materials into the spiritual materials, and it is not possible to directly put the spiritual materials into the molten iron, which will destroy the essence of the spiritual materials, and the spiritual materials cannot be placed too far, so it is very inconvenient for the people who refine the tools to control, and Lang Fei Yuanqi, the refining tool is very costly, and too much Lang Fei Yuan Qi will definitely affect this process。

Liu Shi has been following Wan Kai refining for a while, and he is already familiar with placing spiritual materials, only to see that the same spiritual materials were put in by Liu Shi and quickly integrated into the molten iron under Wan Kai's control. There is a trick here, you need to manipulate the spiritual material and the molten iron to slowly fuse, not only not to damage the spirituality of the spiritual material, but also to properly integrate evenly.

"Wow" The molten iron stirred, slowly condensing into the shape of a sword, which was a sword fetus. All the spiritual materials were fused, and the sword embryo of sword refining suddenly appeared. At this time, what Wan Kai needed to do was to carve the talisman array on the sword embryo. The talisman array Wan Kai used was already well ripe. I saw Wan Kai's right index finger tapped, and a burst of vitality shot out, and then I saw this vitality like a carving knife on the sword embryo to draw a deep imprint.

Wan Kai's fingers moved slowly, and a rune line appeared on the sword embryo. There are a total of five runes in this rune array, and the structure is also very simple, basically like drawing a circle, but it is not really a circle.

"Two. Wan Kai silently thought in his heart, as long as he completed the engraving of the rune array, he would be considered to have completed half of the refining. The third rune begins to be carved.

Yang Chen went out to look for a long time and did not find the source of the fire, and when he returned to his residence, there was no trace of Wan Kai and the others. I suddenly remembered that Wan Kai had said that he was going to Huoyuan Cave to refine the first spiritual weapon today, and said that he would let him go to help, but he didn't expect to forget it this morning, and scolded himself for being damned. Fortunately, Wan Kai left him a token to enter the Huoyuan Cave, took the token and rushed to the Huoyuan Cave.

Huoyuan Cave is the important place of Yanyun Peak, it is not how difficult to find, and there is a token where it passes, but the path here is a little difficult to walk, but after casting the fallen leaf fragrance**, it also becomes like flat ground, Yang Chen only found that the fallen leaf fragrance** has such a use.

When they arrived at Huoyuan Cave, Wan Kai and the three of them were concentrating on refining weapons, and no one noticed his arrival. Yang Chen stood in the distance, afraid that it would affect the Wankai Refinery.

Yang Chen naturally understood the talisman array depicted by Wan Kai, but it felt like it was too simple. When Wan Kai depicted the third rune array, Yang Chen was also pleased, because Wan Kai carried out it very smoothly. At this moment, a string of flames suddenly broke out in the Ding furnace, which was the expression that the fire vitality in the mountain was not stable enough, but for Wan Kai, it was like a thunderbolt on a sunny day, at this time, he had to control the sword embryo, but also control the depiction talisman array, and his energy and fire vitality were already the biggest on this. The sudden burst of fire hit the sword embryo, and the sword embryo was shaken, and the sword embryo at this time was just a molten iron that was gathered together with the control of vitality, and it would be dispersed in an instant if it was affected by this.

Wan Kai's heart tightened suddenly, and he hurriedly increased the power of the vitality in his left hand to control the sword embryo, but fortunately, the sword embryo was only slightly shocked and did not appear abnormal. But it was just such a mental point, Wan Kai's right hand suddenly trembled, and the depicted rune line appeared strange at this time, but the rune line that was originally straight suddenly appeared a horizontal hook, which was never allowed by the rune array, which means that the rune array has failed.

Wan Kai was lonely, and he didn't expect to fail after preparing for so long. Liu Shi and Mo Kongsheng both noticed Wan Kai's abnormality, and their excitement suddenly dimmed, not only Lang Fei Lingcai, but also Wan Kai's psychology was not comfortable.

"Control zhì good sword embryo. Yang Chen let out a loud shout, and suddenly appeared behind him. Wan Kai also woke up at this time, even if he couldn't refine a spiritual weapon, he should still be able to refine a good ordinary weapon with the sword embryo intact. Immediately, the control of the vitality was increased, and the sword embryo was intact and stable in the Ding furnace.

Suddenly, Yang Chen's right index finger pointed out, and there was a burst of fire vitality shooting out just right on the sword embryo, this is Yang Chen painting a gourd in the same way, his ghost car spirit element is a spiritual object, and it is also handy to use it at this time, the depth of the vitality carved into the sword embryo is the same as Wan Kai's, and it happens to be connected with Wan Kai's broken line. I saw that his fingers were swiped continuously, like a pen walking a dragon and a snake, but for a moment, dense runes had appeared on the sword embryo.

This greatly exceeded Wan Kai's expectations, Yang Chen not only connected half of the runes he had carved, but also carved a rune array that was countless times more complex than his own rune array. Yang Chen's forehead was sweating slightly, and it slowly slipped down and hung on his eyelids, although it was a little eye-catching, but Yang Chen's eyes did not move a bit.

"Done. Yang Chen suddenly burst into a shout, only to see that the runes on the sword embryo emitted cyan light at this time, which was depicted by Yang Chen according to a grain of dust rune array, although it was a little out of shape, but it was a complete depiction of a grain of dust rune array. The horizontal hook carved by Wan Kai happened to be used by him and turned into a part of the rune array.

Wan Kai could see that Yang Chen had completed the rune array, and it was a rune array that was many times more complicated than his own. After listening to Yang Chen's drinking, Wan Kai immediately slapped his palm, and a somewhat dry branch appeared in his hand. "The green spirit branch is fused. With a loud shout, Wan Kai threw the green spirit branch into the sword embryo.

"Woo" There was a rapid trembling sound in the Ding furnace, and then I saw a cyan brilliance diffused from the sword embryo.

"Smelting!" Wan Kai's technique is surprisingly fast, and the most difficult joints are also in the past, and he is already familiar with the rest of the process. The pale golden flame swayed in the furnace, and the crimson blue of the sword embryo became even thicker. The runes carved by Yang Chen slowly disappeared in the smelting, and then the sword embryo became solidified in the flames, the molten iron slowly solidified, and the substantial sword body appeared in everyone's eyes.

"Ironing" Wan Kai's palm flipped over, and the flames in the furnace wrapped around the sword body under his control, and the sword body hummed in the flames, and then saw that the sword body gradually appeared shiny, and those uneven places became smooth under the smelting of the flames. After about half an hour, the process was finally completed.

"Quenching. Wan Kai shouted as he saw a short sword glittering with blue light leaping out of the Ding Furnace at a rapid pace. A cloud of green smoke rose from the pool next to the "snort".

Wan Kai had a smile on his face, obviously done. Yang Chen, Liu Shi, and Mo Kongsheng's nervous expressions finally eased. With Wan Kai's smile, he also laughed loudly. Refining a spiritual weapon means that Wan Kai's worth will change, and as Wan Kai changes, their status will also increase.

Wan Kai walked over and reached out to take out a short sword that was nearly two feet long from the pool. I saw that the sword turned cyan, and a cyan light flickered when it was waved.

"Hehe, that's good. Senior Brother Liu, give it a try. Wan Kai smiled and threw the Qingfeng Sword casually. Liu Shi took it in his hand, but Jue Qingfeng had a feeling of affection on his sword, and he didn't know what was going on. Wan Kai asked him to try the Qingfeng Sword, he didn't think much about it, and the vitality was condensed into the Qingfeng Sword, only to see that the Qingfeng Sword suddenly became even more blue, and a faint aura of vitality was condensed around the sword body.

"Woo" Liu Shi slashed out, and a cyan circular blade slashed out. "Bang" There was a loud sound on the stone wall of Huoyuan Cave. As the brilliance flickered, the cyan round blade disappeared with it. There is a rune array in the Huoyuan Cave, which is also to prevent the refined spirit weapon from being too powerful and damaging the cave hall.

Liu Shi was surprised: "So powerful!" He had also used a lower grade spirit weapon, but it was not as powerful as this Qingfeng Sword. The Blue Blade Sword seemed to have expanded the power of his Yuan Qi by more than ten times. If you use such a spiritual weapon to fight against people, it is equivalent to increasing your strength tenfold. Suddenly, a realization flashed in his heart, and Wan Kai asked him to try the Qingfeng Sword obviously had a deep meaning.

"Hehe, how is Senior Brother Liu, this Qingfeng Sword is not bad, right?" Liu Shi nodded, and Wan Kai also saw from Liu Shi's eyes that Liu Shi was quite satisfied with the Qingfeng Sword. "The array eye spirit material used in this Qingfeng sword is the green spirit branch, which belongs to the wood system, so the rune array on this sword also has the characteristics of the wood rune array, so the most suitable user of this sword should be a person who cultivates the wood system, and only those who cultivate the wood system can make it exert its maximum power. If Senior Brother Liu likes it, this sword will be given to you. Wan Kai smiled and said eloquently.

Liu Shixi said: "Thank you, Senior Brother Wan." Then he looked at Yang Chen, Yang Chen nodded slightly, he naturally knew what Liu Shi meant.
