Lingyi's mantra is a little difficult to understand, Xiang Yun sometimes frowned, sometimes paced around, sometimes suddenly realized, the whole person fell into a state of enlightenment. Although these words are not long, they really took Xiang Yun a lot of time.

Since many of the words in it are ancient characters, and some have been lost, so during the comprehension, Xiang Yun also had to go to the library of the sect to check some classics about ancient texts, and Xiang Yun had the impression that there was such a book.

After returning to the cave after the investigation, Xiang Yun began to meditate again, and after three full days of retreat, he finally understood it. The method of using the spirit wing has been completely mastered by Xiang Yun, and the corners of Xiang Yun's mouth are slightly raised, and his mood is very happy. After resting for a while, I couldn't wait to start preparing for the sacrifice of the "Spirit Wing".

Xiang Yun took out the spirit wing from the storage bag again, the spirit wing was still very light and thin, and Xiang Yun cast a spell to make it float in the air. Then the double killing pinched the trick, and one after another complex handprints were struck, and one by one complex runes drilled into the floating spirit wings.

Xiang Yun kept sealing, and at the same time, the spirit wings also changed a little. The spirit wings, which were almost invisible to the naked eye, were slowly revealed, gradually becoming clear. When the spirit wings were in a translucent state, Xiang Yun stopped sealing. Carefully using spiritual power to control the spirit wings, the spirit wings were sent to Xiang Yun's back, at this time, the spirit wings seemed to be very spiritual, and took the initiative to step forward and combine with Xiang Yun's back, and a silk-like substance stretched out from the spirit wings, directly penetrating Xiang Yun's skin and melting into the flesh and blood.

Xiang Yun had long known that this process would be very painful, but he still couldn't help but convulsions all over his body in pain, and he almost wanted to fall into a coma. Of course, Lingyi won't care about this, now even if Xiang Yun wants to stop, he can't do it, Lingyi goes deep into the bones inch by inch, and the place where Lingyi and Xiang Yun's back are combined is bleeding.

Xiang Yun bit his lip, the blood on his lips stimulated him to wake up, and with great pain, he continued to pinch, the same rune drilled into his own body this time, and the fusion of spirit wings gradually accelerated.

Although it was only less than an hour, it seemed like a long time had passed for Xiang Yun. Finally, the spirit wing completely fits with Xiang Yun's body, and at this moment, the spirit wing completely belongs to Xiang Yun. Xiang Yun's eyes darkened and he fell asleep. The wound on his back began to heal, and the spirit wings flickered and absorbed the aura of heaven and earth, still attached to Xiang Yun's body.

When Xiang Yun woke up again, there were no traces of the wound caused by the spirit wing, and the fatigue of his body was gone. He was inevitably a little excited, although the cultivation process was very difficult, but the result was still very satisfying.

Xiang Yun touched the wings behind his back, they were furry, just like the real thing, and he didn't have to worry about being misunderstood by someone seeing the wings, the wings could be withdrawn, as long as Xiang Yun moved his heart, it would become a feather mark attached to Xiang Yun's back.

Xiang Yun flapped his wings happily, but suddenly hit the stone wall, and Xiang Yun touched his nose in embarrassment. Forgetting that he was still in the cave, Xiang Yun was not in a hurry to experiment with the effect of the spirit wing, and if he wanted to come to the Heavenly Spirit Treasure, he would definitely not let himself down.

In fact, what is recorded in the mantra of the spirit wing is not only the method of opening the spirit wing, but Xiang Yun does not have much to grasp now, and the mantra is still too difficult for Xiang Yun now. The first part of the Spirit Wing Mantra describes how to open the Spirit Wings and some simple ways to use them, such as using feathers to attack, defend, and so on. At this time, Xiang Yun simply connected the methods of attack and defense.

Then Xiang Yun slept comfortably, after all, in order to cultivate the spirit wing, he had already spent too much of his mind.

When he woke up, Xiang Yun was a little embarrassed, and now he had two choices, first, continue to practice the exercises and strive to build a foundation as soon as possible, and second, practice some simple spells and supernatural powers to prepare for the sword test conference.

Xiang Yun chose the latter, I am afraid that he will not be able to break through the foundation building period in a short period of time, so it is better to put his hope in the Sword Trial Peak. But although it is difficult to improve his cultivation for a while, there are many ways to improve his strength, such as his current thoughts.

Xiang Yun can be regarded as half of the foundation now, and there are already a lot of spells that can be cultivated. As one of the giants in Qingzhou, Yanyunmen has a relatively rich collection of books, and there is naturally no shortage of spells.

But these books are not like the books that Xiang Yun read in the library before, the books that Xiang Yun read before were not very important and open to all disciples, and these exercises need to be exchanged for the contribution points of the corresponding sect. Xiang Yun naturally doesn't have any so-called sect contribution points.

There was no way, Xiang Yun had no choice but to send a transmission note to Yi Lan.

Not long after, Yi Lan came to Xiang Yun's cave mansion. threw a bunch of jade slips to Xiang Yun, the jade slips were used to record, and it seemed that Yi Lan went to the library to rub them.

"It seems that the identity of this core disciple is not useless. Yi Lan laughed at herself and said, "Why do you want these spells? You don't have much spiritual power, how many times can you use them?"

"Who said that I don't have much spiritual power, and it's always enough to put some low-level spells if I don't have enough!" After speaking, Xiang Yun unceremoniously drove Yi Lan out, "I'm going to start cultivating." ”

......

Yi Lan was a little speechless, and said in a low voice, "What a cultivation madman." ”

Xiang Yun naturally didn't know what Yi Lan said about him, and at this moment he was concentrating on reading the jade slip sent by Yi Lan.

Most of them are low-level spells, and only one spell called "Ten Thousand Swords Technique" is a medium-grade spell, Xiang Yun has already learned some low-level spells before, so he has little interest in low-level spells, and he began to study Ten Thousand Swords Technique. But after all, the Ten Thousand Sword Technique is a medium-grade spell, and in terms of Xiang Yun's current spiritual power, it is really not enough, and he can barely send out one blow.

Xiang Yun was a little distressed, but he didn't want to give up. Because if he uses spiritual power to connect, his efficiency will be very low. So he silently comprehended the magic formula, understood every mudra, and then simulated it in his mind, and his divine consciousness unconsciously began to simulate the casting method of the Ten Thousand Sword Technique, over and over again.

When Xiang Yun thought it was about the same, he began to experiment, and this time, he used spiritual power. Both hands quickly pinched and sealed, and there were words in their mouths, it seemed that the momentum was indeed very strong, and the spiritual power in the body was quickly mobilized. Xiang Yun's eyes lit up, "Ten Thousand Sword Technique!"

After a few seconds, Xiang Yun still maintained the same posture as before, however, nothing happened.

Xiang Yun smiled awkwardly and touched his nose, "No, where did you fail?"

While recovering his spiritual power, he reflected on the spell casting process just now. In my mind, my consciousness began to replay the process just now, over and over again. Suddenly, Xiang Yun suddenly stood up, "I know, it's because I pinched an extra seal!"

The more Xiang Yun thought about it, the more he felt that he would definitely not be wrong this time, and finally his spiritual power recovered, and he began to try again, and the result was ......

Xiang Yun was also a little speechless, and had to continue to deduce again and again in his mind.
