Yang Chen felt that the twelve bee spirit swords were a pity, and unloaded them in advance.Once the Three Spirit Ding Furnace was melted, Yang Chen would immediately start to re-condense it. The size of the eight auxiliary swords and the method of condensation Yang Chen had already memorized it, and the ancient refining method was more complicated, which also took Yang Chen a lot of time. Three hours later, the Sanling Ding Furnace melted into a pool of molten iron, and there were black particles floating in the molten iron, which was the impurities and the waste residue of the rune array that appeared after remelting, the higher the quality of the refining flame to the spiritual material, the more in place the calcination of the spiritual material, and the spiritual material would also be refined and purified by the maximum Cheng dù, which is the reason why the quality of the spiritual weapon refined by the refiner is different. The higher the cultivation, the higher the quality of the spiritual fire that can be controlled, and the more condensed techniques will be, so that there will be a huge gap between the spiritual weapons refined.

Yang Chen's fingers swiped, and the vitality shot out, and the floating black particles were cleaned out little by little, and in the end, only the red molten iron remained. Yang Chen's fingers quickly scribbled, and the Dao Yuan Qi was sometimes like a cutting knife, and sometimes like a gripper to split the red molten iron, a total of eight parts, but the amount was a bit much. The most important thing in refining is the weight of spiritual materials, not the more the better, but just right. As soon as the mind moved, the vitality soared, and some of the molten iron were separated from each part of the molten iron, and these separated molten iron melted together to become the ninth molten iron.

At this time, it was the most critical moment, because Yang Chen had to control every piece of molten iron and refine the molten iron into auxiliary swords one by one, the loss of divine consciousness was not only huge, but also the consumption of vitality would also increase exponentially, not only requiring a strong divine sense, but also sufficient vitality in the body. "Condensation!" Yang Chen burst out, a piece of molten iron was mentioned to the top of the golden flame, Yang Chen's palm was changing continuously, and the molten iron also changed its form, and after half an hour, the molten iron became the appearance of an auxiliary sword, this auxiliary sword was like a dagger but no handle, like a dart and too long, but on the whole it looked like a feather or a silver shuttle, sharp and light. Seeing the first auxiliary sword condensed, Yang Chen's heart was also much calmer, he was a little nervous before, after all, this was the first time to refine a weapon according to the ancient refining method, and now that the condensation was successful, he also had a great increase in his heart.

The most important thing in refining the auxiliary sword is to make the auxiliary sword and the main sword compatible, otherwise it will not only fail to increase the effect, but will become a burden, which is equivalent to adding to the snake. The auxiliary sword designed by Fei Zhenjian is like a guard carried by the master, enhancing the power of the main sword and guarding the main sword at critical moments, which is different from other sets of swords. Therefore, the auxiliary sword tends to be agile and tenacious. The iron used in Yang Chen's Sanling Ding Furnace is the sharpest metal in the world, and the material used in the Nameless Giant Sword is precisely tenacity, which can be seen from the sharp short sword that Yang Chen obtained when he used Kui Jian at the beginning. The auxiliary sword does not need to seal the Yuan Spirit, so after the refining is successful, it only needs to engrave the rune array with the main sword.

It was already night when all the auxiliary swords were successfully condensed, and there was a night pearl on the roof of the refining room here, and at night, it would glow, like a star in the sky, and the night pearl was already as bright as a star. Yang Chen was already exhausted, he had never been able to refine like this, and at the last moment, he couldn't support it anymore, his divine sense was exhausted and he felt drowsy, and his vitality was exhausted like a land that had not rained for three years, if it weren't for Yang Chen's ability to refine while absorbing vitality, it would definitely be a failure.

Yang Chen sat weakly on the floor, letting out a long breath, feeling dizzy, and then he didn't know. "Is it morning?" Yang Chen stretched out and opened his eyes in a daze. When I woke up, the pearl was still lit up, and the skylight was faintly shining. The quenching of iron in the Fire Cloud Room uses a water tank, not a pool, and the water tank is flowing living water, and the refining spirit weapon is more pure. Looking at the eight auxiliary swords lying quietly in the sink, Yang Chen smiled with satisfaction, the eight auxiliary swords were reflected by Qing Lingling's water, and the cold waves rippled, and it seemed that his refining level had risen to a new level.

Next, the second step is coming, because the Feizhen Sword and the eight auxiliary swords are not refined in the same period, and the main sword and the auxiliary sword need to be returned to the furnace to engrave the rune array in order to integrate the eight auxiliary swords and the main sword. Yang Chen took out the Feizhen Sword and felt his heart surge, this was the second time he had refined a spirit weapon, and the grade might be higher. The Three Spirits Ding Furnace was originally intended to be his natal treasure, but after all, it was a little worse, and now that the re-condensation of the essence blood had been turned into ashes, Yang Chen had already felt that the kind of spiritual feeling between himself and the Three Spirit Ding Furnace had disappeared. Fortunately, Yang Chen used essence blood when refining the Three Spirits Ding Furnace, and if it was a divine soul, it would be troublesome. Even if the essence blood is lost, it will be replenished quickly, but if the soul is damaged, it is not easy to make it up. This time, he didn't want to refine the Fei Zhen Sword into a life weapon, because he saw that the more things that were connected to his life, the easier it was to hurt his life, just like the Three Spirits Ding Furnace, although it was only a trace of essence blood, it was a kind of damage after all.

When Yang Chen was about to refine, he suddenly found that he didn't have the slightest fire energy in his body. Although he didn't concentrate on condensing, Yang Chen's difference from other cultivators was that his qi pockets would absorb and condense the fire vitality on their own, the fire vitality here was so thick, it should be able to fill it up in one night, but on the contrary, there was nothing at all. Yang Chen felt very strange, there was only one reason for this situation, that is, the fire vitality grade here was too high for him to absorb.

Yang Chen tried to cultivate for a moment and found that this was really the case. All the fire energy in the fire cloud room was absorbed by the golden flames in the refining cave, and no matter how it operated, it couldn't be absorbed into the silk. "This flame is really amazing!" Yang Chen admired, but he also thought of a way to try again, that is, to condense the formation around the golden flame, and use the formation to condense the fire vitality for his own use.

The formation was condensed and formed, and the vitality was injected, but the formation was slowly running. There was a strange buzzing sound around the "Hum, Hum" formation, and it seemed that there was a force that wanted to break through the formation, but that force seemed weak and hesitated. Yang Chen found that it was not the power of the cultivator, but from the rune array. It's just that this rune array seems to be suppressed by his own formation and can't exert its due strength, Yang Chen feels that it should be the rune array around the cave entrance, but what he didn't expect is that there is also a difference in rank between the rune arrays, like cultivators, those with low cultivation are suppressed by those with high cultivation. However, his formation diagram is so simple that it should not be as powerful as the rune array around the hole, but it just suppressed the rune array around the hole, and he couldn't figure it out for a while, so he had to not think about it.

After the formation was operational, the situation changed, and the golden flame was condensed bit by bit and then infused into Yang Chen's body. Yang Chen felt that this golden flame essence was higher than any kind of fire vitality he had seen, but when it was condensed and entered his body, he felt a heat rising in his body, and the heat of this golden flame condensed fire vitality was not that kind of scorching heat, but with a heaviness, condensation and connotation. By the time Yang Chen's fire vitality was complete, it was already night, and under the dazzling night pearl, Yang Chen began to return to the furnace.

The Fei Zhen Sword and the eight auxiliary swords were all thrown by Yang Chen on top of the golden flames, after the initial smelting, he found that the spiritual materials used in the Fei Zhen Sword were somewhat inferior, completely inferior to the eight auxiliary swords he refined, which was completely unexpected by Yang Chen, and he thought that the predecessors who refined the Fei Zhen Sword would use the best spiritual materials to refine the Fei Zhen Sword, and he didn't want to fight him, it was just a trial. Now, if you simply return to the furnace to engrave the talisman array, you can naturally fuse the Feizhen Sword and the auxiliary sword into one, but the main sword is too weak to withstand the resonance of the eight auxiliary swords. If not, there is only a way to refine the Flying Vibration Sword again. Yang Chen was stunned for a moment, at the beginning, the female elder said that this was a waste sword, and he didn't believe it, but now he finally believes that this is a waste sword.

It could only be re-refined, and Yang Chen didn't want to give up halfway. Yang Chen regained his spirits, he felt a little like vomiting blood just now, and he scrapped the Sanling Ding Furnace that he could still use to perfect this Feizhen Sword, but he didn't expect that the Feizhen Sword was more wasteful than his own Sanling Ding Furnace. The eight auxiliary swords have been successfully refined, and if the large auxiliary swords are changed too much, they will not be used, which is even worse than refining a weapon again. Yang Chen likes the appearance of the Flying Sword, the shape of a flying bird. After thinking about it, it was decided to keep the main appearance of the Fei Zhen Sword. Retaining the main body and re-refining, this is called changing the marrow in the refiner. This requires smelting new spiritual materials into it little by little, and replacing inferior materials with inferior ones. This process is extremely difficult, and the slightest carelessness in refining a spiritual weapon will turn into a waste product. Yang Chen also knew the risks, but was there any other way to think about it.

There were still two magnets left in Yang Chen's essence sea, and the extra spiritual material from the Sanling Ding Furnace when refining the auxiliary sword should be enough. Yang Chen smelted the remaining piece of spiritual material iron from the Sanling Ding Furnace and the Feizhen Sword together, because the spiritual material iron was unfinished after smelting, it melted faster, and at this time it had already turned into molten iron. The Flying Zhen Sword was suspended above the golden flames, slowly showing signs of melting. Under Yang Chen's control, the molten iron melted into the Feizhen Sword little by little, and the essence of the transformation was to let the spirit weapon be in a state of untransformed, and slowly integrate the replaced spiritual materials, and how many spiritual materials should be extracted in a timely manner. Yang Chen's vitality shot out in his hand, on the one hand, he controlled the molten iron to be integrated into the Feizhen Sword, and on the other hand, he controlled the Feizhen Sword to extract inferior materials from it, and he also had to keep the shape and appearance of the Feizhen Sword unchanged, so that the difficulty of refining was more than three times greater.

The iron has also been taken out by Yang Chen, and the iron is quite hard and requires a long time of smelting to turn into molten iron, and it can't wait for the remaining spiritual materials of the Sanling Ding Furnace to melt before smelting. I only remember that the night pearl lit up twice, Yang Chen had already integrated all the spiritual materials into the Feizhen Sword, in addition to the remaining spiritual materials of the Iron and the Sanling Ding Furnace, Yang Chen also smelted part of the horns in the Jinghai into it, which could enhance the flexibility of the Feizhen Sword, and the waste materials that were refined were also directly thrown into the refining hole and turned into ashes.
