With the strength of the Ghost Ember Burning Fire, as well as Lin Feng's own alchemy attainments, at the peak of the Mahayana period or even earlier, Lin Feng definitely had a chance to attack the refining master. But firstly, Lin Feng was relatively busy, and secondly, how long did it take for Lin Feng to reach the Diyuan Realm from the middle of the Mahayana period?

Because of this reason, Lin Feng failed to break through to the refining master level during the Mahayana period.

Now that the Yuyang Mountain Range has been unified, the daily trivial matters of the Yanyang Sect do not need to be entangled by Lin Feng. In addition to often appearing among the new batch of disciples and giving everyone a word of explanation, Lin Feng finally had more time.

The gap between the peak of the Mahayana period and the Earth Yuan Realm is indeed a bit big. During the Mahayana period, there were very few cultivators who achieved the honor of refining master or alchemy master. But after arriving at the Earth Yuan Realm, as long as the natal true fire is not as extreme as the Purple Mansion Thunder, generally speaking, even if the original energy spent on alchemy and alchemy is less, at most when it reaches the Earth Yuan Realm Double Heaven, it will almost be able to refine the spirit weapon-level magic weapon.

And the strength of burning the fire with the forest wind and the embers, as well as its already excellent refining talent. In fact, not long after the incident of Baiyuemen passed, Lin Feng became a refining master who could refine a spiritual weapon-level magic weapon.

Lin Feng's ability to refine the pill, with the teaching of Old Man Long, has also reached above the level. Lin Feng's alchemy technique can reach the level of a refining master, and whether it is the flame temperature or the ability to control fire, since it has met the requirements for refining a first-grade spirit weapon, it must also meet the requirements for refining a first-grade spirit pill.

If Lin Feng is given a certain amount of time, there should be no problem in raising his alchemy ability to the level of an alchemy master. However, Lin Feng was not busy starting the cultivation of alchemy.

The current situation of the Yanyang Sect did not require Lin Feng to be able to refine the earth-level pill in a short period of time. On the contrary, it was the "Nine Heavens Xuan Array Catalogue", Lin Feng had already wanted to cultivate a long time ago. Now that I finally have time, I can't even take care of improving my alchemy. Lin Feng plunged headlong into the "Nine Heavens Xuan Array Catalogue".

With the improvement of Lin Feng's realm, Lin Feng's current vision has also improved too much compared to the beginning. However, Lin Feng's hopes for this "Nine Heavens Xuan Array Catalogue" did not decrease with the improvement of Lin Feng's realm.

The higher Lin Feng's level, the more he found that the value of this "Nine Heavens Xuan Array Catalogue" was definitely amazing.

What is recorded in the "Nine Heavens Xuan Array Catalogue" is the refining formation, and the cultivation realm generally divides the formation into three series, the sect big array, the battle array, and the refining array. There is no superiority or inferiority among the three series, but for Lin Feng's instrument cultivation, of course, the refining formation is more attractive to Lin Feng.

Now Lin Feng already knew that the value of the Lingjian method of recording the layout method of the ground level refining weapon formation was actually quite high. Moreover, the vast majority of such Lingjian often only records the relevant information of a formation inside.

But even so, a spirit that records the first-grade refining weapon formation of the ground level is enough to make a large number of lower three realm weapon cultivators fight.

Generally speaking, there are three important factors that affect the grade of a magic weapon that is about to be refined. The ability of instrument repair, the grade of the formation, and the grade of the material.

The grade of the material is the foundation, no matter how strong the instrument cultivation is, it is impossible to refine the spirit weapon-level magic weapon with all the materials of the yellow level.

The grade of the refining formation arranged is logically counted in the ability of the cultivator. But here I have to take it out and talk about it separately.

The Xuan-level refining formation is okay, in fact, the ground-level refining formation is quite scarce in the cultivation realm. If the background of the forces to which they belong is not very profound, some of the Wild Road's Earth Yuan Realm Triple Heaven Weapon Cultivation still uses the top-level refining weapon formation of the Xuan Rank when refining magic weapons.

It's not that these cultivators are reluctant to buy any blueprints of ground-level formations, it's really that the blueprints of ground-level formations are indeed too scarce. The vast majority of instrument cultivators can't buy even if they have spirit stones.

The spirit of the Nine Heavens Xuan Array Catalogue is sealed by spiritual consciousness, and if you want to see the specific formation information in it, at least until the monk has the soul strength of the Mahayana period, in other words, the realm of Mahayana level state of mind cultivation.

When Lin Feng was just a little guy in the Jindan period, he only saw the first paragraph of Lingjian, which was the background introduction of the first Chiyun Zhenren to the "Nine Heavens Xuanjing Array Catalogue", and in addition, there was only one name left for the "Beidou Heaven Swallowing Array".

After breaking through to the Mahayana period, no matter how tight Lin Feng's time was, he still had time to read some information from the spirit of the Nine Heavens Xuan Array Catalogue. However, with Lin Feng's soul strength at that time, in the end, he only read the specific information of the twelve Xuan-level top-level formations. Eight ground level formations, Lin Feng saw the name, but after all, he still couldn't see the specific content.

But no matter what, the formation of the eight ground levels was definitely enough for Lin Feng to be shocked. Lin Feng, who was still in the Jindan stage at that time, didn't know what this meant, but as Lin Feng's knowledge grew, Lin Feng was already very clear now. As long as one of these eight earth-level formations has reached the grade of the fourth-grade ground-level, then the value of this "Nine Heavens Xuanyuan Array Catalog" is no less than the value of any seventh-grade spiritual weapon.

With the refining formation of the fourth-grade earth-level and the refining materials of the fifth-grade ground-level, the sixth-grade spiritual weapon can almost be refined. However, if there is only a third-grade refining weapon formation of the ground level, if you want to refine a six-grade spiritual weapon, in terms of materials, at least the main material must be above the sixth-grade level.

Therefore, if you can refine the weapon with the refining weapon formation of the fourth grade of the ground level, and refine the spirit weapon of the same grade, you can save a lot of spirit stones. If there are more spirit weapons refined, the spirit stones saved will be considerable.

It's not that the instrument cultivation of the cultivation realm is unaware of this, but it is really a ground-level refining formation, especially a refining formation above the fourth grade of the ground-level, which is really too scarce.

If the twelve top-level refining formations and the eight earth-level refining formations in the "Nine Heavens Xuan Array Catalog" were really completely collected by Chiyun Zhenren himself. For Chiyun Zhenren, Lin Feng had to take a higher look at the original basis.

With the formation of the fourth rank of the earth level, more than half of the first-class forces in the Burning Wasteland Domain did not have such a background. Chiyun real people can get it, this encounter is indeed a bit against the sky.

When Lin Feng used to refine top-level treasures, he still used the combination of Xuan-rank high-grade and Xuan-rank mid-grade formations. Although Lin Feng imprinted the twelve top-level formations of the Nine Heavens Xuan Array Catalogue in his mind through the Lingjian method, he actually still did not have the ability to directly use these formations in the refining weapon.

There is also such a law in the instrument cultivation world, generally speaking, even if the monk has mastered the arrangement method of the second-grade refining weapon formation. Because when refining magic weapons, what often needs to be burned is a combination formation, and the requirements for the mastery of the monk's formation are even higher. In fact, this instrument cultivation can only arrange a combination formation composed of a first-grade refining weapon formation in his own magic weapon.

If you master the layout of the ground-level third-grade refining weapon formation, in fact, when refining the weapon, you can often only use the ground-level second-grade refining weapon formation at the highest.

There are many factors that affect the ability of a weapon cultivator, and Lin Feng is generally much stronger than a weapon cultivator of the same level in terms of flame strength, fire control ability, mana strength, and so on. However, in terms of formation attainment, Lin Feng before was also at an average level.

When Lin Feng was in the middle of the Mahayana period, he had the state of mind cultivation at the level of the Earth Yuan Realm. After experiencing the baptism of the rules of heaven and earth after the tribulation, Lin Feng's state of mind cultivation, although he had not yet reached the realm of the Earth Yuan Realm Double Heaven, but at least at the level of the Earth Yuan Realm One Heaven Realm, Lin Feng's state of mind cultivation was quite high.

Now Lin Feng can already read the specific information of the five earth-level formations from the "Nine Heavens Xuan Array Catalog". Among the five ground-level formations, three are ground-level first-grade refining formations, and two are ground-level second-grade refining formations. Lin Feng couldn't see the specific information of the formation in the back, but it was already obvious that the remaining three ground-level formations must be above the third-grade level. In this way, the probability of having a formation of more than four grades of the ground level is quite not low.

It is said that in this Nine Heavens Xuan Array Catalog, there is also a broken Heavenly Rank Formation. Although it is definitely not possible to refine weapons with a broken formation, since there are formations of this grade. Among the remaining three ground-level formations, there was a ground-level fifth-grade refining formation, and Lin Feng wouldn't feel too unusual.

Lin Feng first began to familiarize himself with the twelve top-level formations of the Xuan Rank, including the Beidou Heaven Devouring Array. After he was quite familiar with these twelve Xuan-level top-level formations, Lin Feng began to cultivate those eight earth-level formations.

This process is not easy.

Lin Feng's formation talent is actually good, and the formation talent is actually largely related to the Fu Seal talent. Lin Feng Fu Seal talent can be described as top-notch, so the formation talent will not be too bad. However, it was really Lin Feng's previous time spent too short on the formation.

It's no wonder that Lin Feng, who let him cultivate for too short a time, but it was clear that Lin Feng had already met all the requirements for cultivating the ground-level formation, just because the foundation of the previous formation was a little unsatisfactory, it added so many difficulties to Lin Feng's process of cultivating the ground-level formation, this feeling was really unpleasant.

The current situation of the Yanyang Sect has stabilized, and it just so happens that Lin Feng needs a certain amount of time to stabilize his realm.

After forcing himself to try again and again, one day, Lin Feng still mastered the layout method of one of the ground level first-grade formations.

After mastering the "Beidou Heaven Devouring Array", the other two formations of the ground level and one product are not a big problem.

After mastering the layout methods of the Beidou Heaven Devouring Array, the Brahma Bagua Array, and the Pure Moon Nine Palace Array, Lin Feng was still not busy improving his alchemy ability, but began to study the two refining formations that had reached the second rank of the ground level.
