This is a book of spiritual cultivation exercises, even if it is just a spirit body, you can directly cultivate into an immortal, of course, this is only a beginner chapter, after all, with Lin Yixuan's current energy points, it is still too difficult to exchange the entire immortal cultivation exercises, but even if it is only a beginner chapter, I believe that it will be of great help to Artoria.

Because of the contract relationship with Lin Yixuan, the two of them can understand the two exercises, and after their initial doubts, they looked at the content of the book with all their hearts, especially Artoria, she found that this book simply opened a new door for her, and let her know that the original world can be so wonderful, and she even felt that she was really a little sitting in the well and watching the sky before.

Soon Artoria was silent and forgot the passage of time, and Jian Tong Sakura was not as addicted as Lin Yixuan, she only knew a little about Gu arts, and it seemed to be very difficult, after all, she understood a lot of things, but fortunately, Lin Yixuan patiently taught on the side.

So Jian Tong Sakura quickly put into it, looking at the way the two of them were invested, Lin Yixuan smiled lightly, there is already time to adjust, so there is enough time for the two of them to learn, the reason why he is so anxious to let the two of them learn is to let them enhance some strength, to be honest, I don't know what to do, Lin Yixuan always has some bad feelings in his heart, obviously now it seems that he has the upper hand, but he doesn't know what Lu Dao is for, he is just a little uneasy.

Moreover, since this world is a nightmare-level difficulty, it is likely that there are more unpredictable dangers, so he must be more cautious.

Let the two of them improve their strength, and they can have more self-preservation. And Lin Yixuan was not idle, he had asked Rin Tosaka for a few gems before, this gem was very close to the power stone needed by the Royal Card, and Lin Yixuan was ready to try to transform it.

Although he may not be able to make this kind of gem, it is always okay to try to transform it, after all, the difference is not too big, as long as it is slightly adjusted, if the gap is too big, Lin Yixuan has no choice.

The adjustment of gems requires great care, so Lin Yixuan laid a formation around his body. Then make adjustments to the gem inside. It is very difficult to adjust the gems that have already formed, but Lin Yixuan has the means to practice weapons, so it is not impossible.

A little bit of adjustment, after a long time. The first gem is finally adjusted. Lin Yixuan felt it again. That's right, it's a power stone now, but the only pity is that the energy stored in it is too weak. However, this is not difficult for Lin Yixuan, he used the formation to start charging the gem, it takes a long time to charge, at this time Lin Yixuan was not idle, continued to carry out gem transformation, and finally more than a day passed, and the first transformed gem reached the limit of the energy it could bear.

Lin Yixuan took the gem and looked at it, it was still a little unsatisfactory, but it had already met the minimum requirements for refining an intermediate card.

This is really good news, at least the intermediate card is completely eyebrowning.

Lin Yixuan continued to adjust and recharge the gems, but unfortunately, not all gems could be adjusted, Lin Yixuan got eight gems from Rin Tosaka, and now only five have been successfully adjusted, and the remaining three have been scrapped.

Five is a little less, but that's all it can be.

After charging all the gems, Lin Yixuan began to refine the intermediate card, in the world of the royal card envoy, only the card above the intermediate card is the really useful card, such as the low-level card, that is completely just a card for beginners, people who have reached a certain level, there are few low-level cards.

Although Lin Yixuan is new to this profession, he is not a beginner, and with his current cultivation, the junior card really doesn't help him much, so he has to practice the intermediate card.

When the other gems were being charged, Lin Yixuan picked up the gems that had been charged at the beginning and began to refine the intermediate cards.

Because it is the reason of inheritance, Lin Yixuan's skills are very proficient, so there is no difficulty in practicing, the only thing needed is time.

When the five intermediate cards were completely refined, seven days had passed, looking at the silver card shining with beautiful light in his hand, Lin Yixuan smiled, five cards, there are four fourth-level cards, one fifth-level card, and the fifth-level card can be regarded as a fluke The successful refining.

Don't underestimate just the fourth-level cards, these cards are very useful, such as the fourth-level cards, which can almost seal the high-level spells that Lin Yixuan can cast now, and the fifth-level cards can almost seal the uncontrollable thunder that was triggered last time, but Lin Yixuan does not plan to seal the spell, but is ready to seal the formation in these cards, although the spell is powerful, but it is easy for people to dodge, Lin Yixuan does not have a special card recovery tool, so once the spell-type card is cast, if it misses, It will take a long time to cast again, but the formation is different, once the formation is cast, it will last for a very long time, and the effect will be very large.

Of course, the fourth-level and fifth-level cards, the formations that can be sealed are also very powerful, Lin Yixuan estimated, even if it was the sword formation used to deal with the thunder god last time, it only needed a sixth-level card at most, so the formation that the fifth-level card could seal was still very impressive.

The formation is powerful, but it takes a lot of time to arrange it, which is a major problem of the formation, such as the sword formation that Lin Yixuan laid last time, even if it was a little prepared in advance, but it took a long time, if it wasn't for Leng Yunwu to block it, he would have let Thor not know how many times he would have divided the corpse.

This is also the disadvantage of the formation mage, and it is precisely because of this that the formation mage is obviously very powerful, but it is not an invincible existence, because no one can arrange a formation in an instant, and even if there is preparation in advance, the arrangement of a formation will take a long time, and the more advanced the formation, the longer it will take, and when you put the formation away, the daylily will be cold.

But if it is sealed in the card, there is no need to be afraid at all, as long as it is summoned, then you can summon the formation that has already been arranged, it does not need to take time at all, it only takes a moment, and you can drag the opponent into the formation.

What is the best formation? Lin Yixuan needs to think about it carefully, in fact, it would be great if he could arrange the sword formation last time, but the first is that the materials are insufficient, and the second card level is insufficient, so he has to retreat to the second, arrange a slightly weaker formation, and with the assistance of other formations, he should be able to cope with most situations.

Lin Yixuan didn't make a decision so quickly, he took advantage of the time to think, walked out of the formation, and looked at the situation of Artoria and Jian Tong Sakura, she went to Jian Tong Sakura first, to Lin Yixuan's surprise, Jian Tong Ying had already finished reading the Imperial Gu Technique, and had already preliminarily comprehended, her Vajra Gu could now be controlled at her will, and she could control the Gu worm to do a lot of things.

And more importantly, she has completely controlled the engraved Gu worm in her body, that Gu worm is completely harmless to her, on the contrary, because it is linked to the magic circuit in her body, it can help her mobilize the magic power in her body and carry out some defense, that is to say, she is equivalent to having a defensive skill, even if it is an attack that she is not aware of, the engraved Gu worm can also help her block it.

Seeing the progress of the Gu Sakura, Lin Yixuan gave her all the eggs of the ancient Gu worms, these Gu worms should be enough for her to study for a while, and after the Gu technique of the Tong Sakura matured a little, he was ready to hand over the cultivation of the Gu worms to her, after all, compared to his own amateur, it was better to be a professional.

After getting good news from Ma Tong Sakura, Lin Yixuan went to Artoria again, but when he saw Artoria, he couldn't help but be a little stunned, Artoria at this time has completely changed, no, it shouldn't be said that she has changed, but that her temperament, her whole person is afraid that her feelings have changed, she is as if she has been sublimated, and she seems to be more aura than before.

Artoria's cultivation talent was really much beyond Lin Yixuan's expectations, which made Lin Yixuan more confident in the decisive battle in the future, but unfortunately, the two clones still hadn't found Illiasfil's whereabouts outside, otherwise he would have really settled down and prepared.

After that, Lin Yixuan walked out of the valley and went to the Medicine Valley to take a look, the construction of the Medicine Valley was already very good, it was more like a paradise, but it didn't seem that it was time for Lin Yixuan to come, because Leng Yunwu was instructing them to cultivate, and seeing their attentive looks, Lin Yixuan didn't bother, just looked at it from a distance, and then returned to the valley to continue to arrange the formation.

He already has the formation in his mind, of course, a big reason for this is that he doesn't know many formations, so there are fewer choices, and after a little exclusion, it can basically be determined.

Ten days later, Lin Yixuan's five intermediate cards have completely changed, although they are still silver materials, but there are more mysterious patterns on them, which look like formation diagrams, but they are plausible.

After the five cards were put into his arms, Lin Yixuan did not rush out, but calmed down to cultivate, in the previous battle, he felt that he had faint signs of breakthrough, because of the constant things before, so he did not calm down to understand, now he finally has some time, naturally he has to cultivate well, after all, in the final analysis, the strength of his own strength is the most critical.

However, things are always full of accidents, and not long after he cultivated, news came from his clone. (To be continued......)
