For Yang Chen's current divine sense, this was not a very difficult process. The divine consciousness of the human immortal has already surpassed all the objects in the mortal world, and it is only a few days of work to enter the divine consciousness imprint.

But this has already shown the strength of the Jiaolong skeleton, and if it is replaced with the same Yuanying peak divine sense as Gao Yue, it will take at least a few years.

It was relatively difficult for the spiritual power to flush out, but under Yang Chen's great yin and yang five elements spiritual power, and under the promotion and tempering of mutual restraint, this process also did not take too long for Yang Chen.

Compared with Gao Yue's decades of water grinding work, Yang Chen completed the process in less than a year. Of course, this is the reason why the dragon bones are not as high as the quality of the dragon horns, and Yang Chen's cultivation is strong, which is also an important key.

Gao Yue only spent almost ten months in retreat before completing the practice. This retreat allowed Gao Yue to completely break the bottleneck of the middle stage of Jindan, and entered the level of the late stage of Jindan, and the spiritual power cultivation realm directly caught up with Yang Chen.

Gao Yue, who had completed the retreat, had been watching Yang Chen's technique. Although almost Yang Chen had never shown any of his superb refining techniques in front of Gao Yue, the only time was the time when the Jiamu Flying Sword was not very superb, but Gao Yue seemed to have a feeling in his dark that Yang Chen would definitely be able to refine this flying sword.

Yang Chen has always been an alchemy master, and no one will doubt this, but Gao Yue just believes that Yang Chen also has superb refining techniques. Even Gao Yue herself didn't know why she felt like this, why she trusted Yang Chen so much.

From this point of view, Gao Yue is very ashamed. As a master, not to mention that he had not instructed Yang Chen in spiritual cultivation, he even asked Yang Chen to guide him in turn. And as a well-known refining master in the Pure Yang Palace, Gao Yue did not even point out any of Yang Chen's content about refining.

OK. Whether it is Gao Yue or Gongsun Ling, they don't regard their future Lang Jun as an ordinary person. Being able to achieve a five-grade alchemist in the mortal world is already a jaw-dropping miracle. I believe that at this time, even Yang Chen suddenly became a refining master. No one was any more surprised.

Yang Chen really did not disappoint the two girls, and after completing the preliminary preparations, Yang Chen began the refining process. It's the same as refining the Armor Flying Sword at the beginning, you have to enter the magic trick first. The body that is hundreds of zhang long is slowly refined to a few feet in length, and then further refining can begin.

The technique of condensing the technique. Yang Chen did it very clearly, and even explained the essentials of how to condense the method one by one, and condensed it very seriously every time. Punch into the dragon bones.

Gao Yue stared intently. Listening to Yang Chen's explanation, although she didn't need much in the future, because the length of the dragon horn was not very long, it also needed to be refined a little, and it could also be used.

Every time the magic trick is punched into the dragon bones, the length of the dragon bones is shortened by a few points. And the completion of each mantra. It almost took Yang Chen at least half a day, and it took him later. As the length of the dragon's bones became shorter and shorter, the process became more and more difficult.

By the time the hundreds of zhang long dragon bones were reduced to less than one zhang, a full three years had passed. Combined with the first year of Gao Yue's retreat, it was already four years.

Only when we do this can we be regarded as reaching a critical moment. At this joint, the Decay Water Flying Sword sent by Taitianmen and some flying swords with the same attributes that Yang Chen had obtained from other places came in handy.

The top-level flying sword that was taken out so that countless people could break their heads and scramble was directly turned into liquid by Yang Chen with Yin Yang Burning Sky, and then added to the Jiaolong bone. There was no hesitation in this process, as if the smelted flying sword was just an ordinary commodity.

If the master who refined those flying swords saw it, he would definitely scold Yang Chen for a dog's blood spray, such a violent thing, it should be punished by heaven.

However, the two daughters present, Gao Yue and Gongsun Ling, did not have the slightest feeling like this. Everything is so natural, in front of this dragon skeleton, the so-called top-level flying sword should be a foil, it should be just an ingredient. I believe that those smelted flying swords will not feel aggrieved if they have spirits.

The last step is the most critical, and Yang Chen is the slowest to do, and the explanation in his mouth is also the most detailed. A lot of the content and techniques are all known and known by Gao Yue, and they are all detailed in the secret biography of the Pure Yang Palace and the secret books of the Taitian Gate.

But under Yang Chen's amazingly accurate technique, these refining techniques, which seemed to be ordinary refining techniques, bloomed with the most brilliant light.

Just like a top master of boxing, it seems that all the moves have reached the realm of returning to the basics in his hands, and there is no need for any high-level fancy things to attract attention.

The same is true of Yang Chen's refining techniques, every technique, Gao Yue will, but such a combination, such precision, and at the same time, it is necessary to take into account the balance of all aspects of the material, every aspect is not missing, and every corner is taken care of.

Gao Yue is a person who knows goods, so he can naturally see the meaning contained in this. For her, this was simply a perfect demonstration operation, which provided her with the best reference for refining the Dragon Horn Flying Sword in the future. With this experience, the success rate of refining the Dragon Horn Flying Sword can exceed ninety percent.

The final process is another year. Seeing that the Jiaogu Flying Sword had begun to slowly take shape, Gao Yue and Gongsun Ling's emotions also changed from surprise at the beginning, to admiration, to calmness, and finally to the joy of success.

The slender Jiao Bone Flying Sword almost maintains the original complete shape of the Jiaolong bone, and even the flying sword is not straight, but slightly bends along both sides of the central axis, like a small snake winding forward. The dragon's skull became the tip of the sword, and the tail part was slightly circled to form a natural hilt.

The flying sword was placed over there, like a long Jiao that would pounce out at any time, but it was countless times smaller, only six feet long, and it was not a complete Jiaolong, but a skeleton without flesh and blood.

This is the most complete preparation for Yang Chen's hands-on refining flying swords so far, all kinds of ingredients are added at one time, unlike the previous flying swords, which are all made first to create a sword embryo and then slowly improve.

This dragon horn flying sword with decancy attribute is a finished flying sword that has been formed at one time.
