After half a month of refining, the appearance of seven spirit swords finally appeared in the Dan furnace. Next, they only needed to engrave the formation and fuse the sword qi of the seven spirit swords into one, so that their sword bodies were connected and their sword bodies separated. The seven spirit swords of different sizes were completed.

Carving formations was already a familiar thing for Li Xiao, even if it was to depict different formations on the seven spirit swords at the same time, it was not a difficult task for him. The whole process was completely portrayed in just half a day. In addition to some of the same formations on the seven spirit swords, there is also a set of seven swords in one formation. Since there is no formation of these seven swords in one, each of these seven spirit swords can be used as a heaven-level high-grade magic weapon.

And the formation of the seven swords in one can make the seven spirit swords connect with each other and become a set of magic weapons. The power can be increased by one or two levels again, which is also the strength of the set. It's just that if you want to refine a combination magic weapon or a spirit weapon, you have to refine it at the same time, which also increases the difficulty of refining. It's not even much simpler than a higher class of magic weapons. This is why complete sets of ritual weapons are very rare.

After carving the formation, the next step is the last and most important step. If they want to exert the power of the complete set of magic weapons, and even make their combination strength to the next level, then this last step of fusion is the most crucial. The fusion of magic weapons can make them have a certain connection in addition to the formation. The quality of integration will determine how close this layer is.

There used to be a set of five-piece magic weapon armor, although they only had the power of the earth-level lower grade alone, but after the complete set, the effect was not much better than that of the ordinary heaven-level lower grade magic weapons. The reason for this is that when they were refining, the extraordinary fusion ratio made them almost indistinguishable from a magic weapon even though they were a five-piece set.

Li Xiao's previous set of magic weapon spirit swords only had three layers of fusion, the main reason was that the seven spirit swords were not refined together, and their materials were not uniform. Therefore, after refining it, Li Xiao was not very satisfied, but these problems could be gradually eliminated in the perennial cultivation, and he didn't have time to collect so many materials, so he planned to settle down. But unexpectedly, when he was traveling through the space, all the spiritual weapons exploded. Although this made Li Xiao very distressed, it also gave him a chance to create these spiritual weapons from scratch. So this time, he wanted to create a perfect set of magic weapons, even if the effect was not as strong as that set of magic weapon armor, but at least it was stronger than the original one.

Under Li Xiao's control, the six red-burned spirit swords in the Dan Furnace rotated rapidly around the huge two-handed sword in the middle, and while rotating, the six spirit swords gradually moved closer to the middle. Soon, the seven spirit swords gathered in the middle, forming a complete two-handed great sword. At the same time, Li Xiao suddenly increased the input of the spiritual fire, and before long, the seams of the seven spiritual swords became smaller and smaller, and in the end, they almost completely disappeared. At this point, the first step of integration is complete.

Next, Li Xiao hit the Dan furnace with a piece of spiritual power, and seven spiritual powers shot out from the Dan furnace to hit the big sword. A burst of light flowed, and the formations on the seven spirit swords that formed the big sword were instantly activated and connected together.

With the operation of the formation, the aura on the seven spirit swords gradually began to merge. From one layer, two layers, and three layers, after knowing that after half an hour, the fusion degree of the spirit sword reached the height of the fifth layer. This is far more than the original set of magic weapons that only have three levels of fusion. The vast majority of complete sets of magic weapons can only reach this point, and very few can reach the sixth layer, let alone more than six layers.

It's just that Li Xiao is not very satisfied, but after the fusion degree reaches the fifth layer, no matter how he runs the formation like this, he can't go any further. Seeing that he could only go so far, in a hurry, a flash of inspiration suddenly flashed, and Li Xiao directly forced out a few drops of essence blood from the tips of his fingers and ejected them directly into the Dan furnace. Wrapped in aura, these few drops of essence blood smoothly met with the seven spirit swords, and quickly merged into them.

The essence blood itself is the essence of the human body's blood, and Li Xiao is a body cultivator, and the essence blood is much purer than that of ordinary monks. After absorbing these essence blood, there was suddenly a trace of spirituality on the seven spirit swords. At the same time, Li Xiao also felt a feeling of blood connection. It's like the seven spirit swords are a part of himself.

Under the influence of Li Xiao's essence blood, the fusion degree of the spirit sword took another step forward, surpassing the sixth layer, but it had not yet reached the seventh layer. Seeing this, Li Xiao was overjoyed, it seems that this method is effective. Then with another wave of his hand, a few drops of essence blood floated in. However, after absorbing these essence blood this time, the fusion degree of the seven spirit swords only increased slightly, as if they had absorbed enough essence blood to saturate before.

Li Xiao didn't believe in evil and threw out a few drops again, this time the effect was even lower, it could be said that it was very small. Seeing this, Li Xiao finally gave up, in this state, even if he squandered the essence blood in his body, he would not be able to increase the fusion degree of the seven spirit swords to the seventh layer.

However, Li Xiao did not give up, it was rare to have such an opportunity to refine from scratch. If you miss it, you may not be able to refine it again in the future. Therefore, if you want to refine the best, you will refine the best. Since the commonality between the essence and blood can be used to improve the degree of integration, what about joining the other ones that are also related?

Thinking of this, Li Xiao didn't say a word, his left hand continued to control the Dan furnace, and his right hand was directly on his forehead, while his eyes were closed. After a while, the right hand on the forehead slowly pulled outward. And behind the fingers of his right hand, closely followed by seven white almost transparent sword-shaped souls, these seven sword souls were the sword spirits of the seven spirit swords before Li Xiao.

The Seven Dao Sword Spirits were all hidden in Li Xiao's soul after the sword body was shattered, and after such a long time of recovery, they had almost recovered. Originally, it was going to wait until these seven spirit swords were cultivated before injecting them into the sword body, but now Li Xiao was ready to integrate them into the sword body now. Because these seven sword spirits were cultivated by him with his own essence and blood, they themselves were a branch of Li Xiao's soul. Naturally, they are also very closely connected. Therefore, Li Xiao hoped to improve the fusion of the sword body through the connection between them.

Under Li Xiao's careful protection, the seven sword spirits slowly floated into the Dan furnace. Then, under the protection of the aura, he quickly found the corresponding sword body and integrated into it. Not long after the sword spirit merged, the giant sword composed of seven spirit swords suddenly emitted a soft light. The appearance of this light meant that he had become a spiritual weapon in the true sense of the word, although it was only a low-grade spiritual weapon of the yellow level.

At the same time, with the injection of the machine spirit, the fusion degree between the seven spirit swords slowly increased again, and finally stopped at the point of seven and a half layers before finally stopping. This fusion degree was already very high, and the set of magical armor back then had only barely reached the height of the ninth layer. Li Xiao believed that under his long-term cultivation, the fusion degree of these seven spirit swords could be further improved, and it was not very difficult to reach the eighth layer.

Li Xiao was already very satisfied with this result, and when this set of spirit swords were combined, the power exerted would definitely not be worse than that of a yellow-level high-grade spirit weapon. It's even stronger than an ordinary yellow-level high-grade spirit weapon.

Li Xiao was satisfied with the removal of the spiritual fire, and then a spiritual weapon hit the Dan furnace, directly shaking the top cover of the Dan furnace. Immediately afterwards, a crisp sword roar sounded, and at the same time, a powerful sword qi rushed into the sky, if it wasn't for Li Xiao's preparation, at this time, this sword qi had already split the mountain rock above his head, and the entire cave mansion might collapse.

Looking at the huge two-handed sword floating in front of him, Li Xiao felt a strong sense of pride in his heart. At the same time, the intimacy on the sword made Li Xiao, who was far away from home, feel like a family member.

With a wave of Li Xiao's hand, the big sword quickly split into seven spirit swords of different sizes and shapes, lined up in front of him. Then Li Xiao began to move with both hands, and the seven spirit swords also flew up and down with his movements, and the feeling of pleasure like an arm making a finger made Li Xiao deeply intoxicated, and the so-called random movement of the heart was nothing more than that. The casting of essence blood and the cooperation of the soul made it effortless for Li Xiao to control these spirit swords, which was not much different from controlling his own body.

As if infected by the spirit sword, the Dan furnace, which no one controlled, suddenly flew up automatically, and then twisted its body and swirled in the air. Seeing this, Li Xiao simply let go of the control of the seven spirit swords and let them play freely. The seven spirit swords immediately turned into children's shapes and began to shuttle freely in the air, flying up and down, chasing and fighting.

Li Xiao looked at it with a smile, then walked out of the stone room and let them play in it by themselves. When he came to the stone room where Qin Feng was, he saw Qin Feng sitting in the phantom array, his brows sometimes furrowed, sometimes upward. Looking at the flickering light on the phantom array, Li Xiao knew that he had entered the third layer of the illusion at this time.

Looking at his expression at this time, there was a hint of pins and needles in his serenity, as if he was not completely immersed in it. This situation shows that although his memory is sealed, he still subconsciously rejects some things in the illusion. It's just that Li Xiao doesn't know how long he has been in, because the longer the time, this rejection may become weaker and weaker, until he is completely synchronized by the illusion in the end. If he doesn't even feel the slightest sense of rejection, then it's basically impossible to come out. But if the time drags on for too long, the chances of the same coming out will be very slim.

Li Xiao was able to come out back then, and there was also a certain element of luck in it, if it wasn't for the conflict with his subconscious in the illusion, then he wouldn't be able to discover the problems inside, in that case, there would be no current him.
