The appearance of magic weapons can be said to have greatly improved the combat effectiveness of immortal cultivators, but the heavenly and earthly treasures that can refine magic weapons are not just a random kind, although theoretically all things can be transformed into aura, but the thinner the aura, the higher the cultivation required to transform it into a spirit state, and the higher the level of heaven and earth treasures, the easier it is to transform it into an aura state.

Therefore, after countless years of balanced development of immortal cultivators, the most suitable level for refining magic weapons lies in the Jindan period, which not only meets the needs of cultivation, but also does not have the heavenly materials and earth treasures required to refine magic weapons under this cultivation to the point that it is difficult to find in a realm.

However, although the scope is a little wider, it does not mean that there are many heavenly and earthly treasures of this level, after all, those that can be called heavenly materials and earthly treasures are all things that have a great effect on monks and are scarce, and the heavenly materials and earthly treasures that can reach the level of refining magic weapons are extremely rare, so immortal cultivators start from the two standards of aura and rules, and combine the three levels of heavenly materials and earthly treasures.

Among them, the human-level standard is the standard for refining spiritual weapons, which can allow the spiritual energy to pass freely without producing loss, and those things that can refine magic weapons can only be called spiritual objects contaminated with spiritual energy at most.

The standard at the prefecture level contains an independent and special rule system, which contains Taoist rhyme. Specifically, the formation of spiritual objects is inseparable from the aura, such as the spiritual spring, the spiritual veins of these spiritual energy sources in the initial stage of formation and the specific physical intersection, in order to form the earth-level heaven and earth treasures, so where it is located, often can find a large number of derived spiritual veins, which is the core part of this spiritual land.

As for the heaven level, it is very rare, and it is not even a specific standard. In the world of cultivating immortals, some treasures with extremely perfect internal rules will occasionally be unearthed in the long period of time, and the power of refining them into magic weapons is far greater than that of ordinary magic weapons, so immortal cultivators divide them into a separate heaven level, guessing that this may be a precious treasure left over from the time when the world was just formed.

Immortal cultivators are not too clear about the division of heavenly materials and earth treasures, because there is no high or low Tao, even if it is the same kind of heavenly materials and earth treasures, the power shown by the different molding environments is also different, and some level heavenly materials and earth treasures may not be too good in terms of comprehensiveness, but sometimes there will be some extreme properties, and these properties are not inferior to earth-level heaven and earth treasures.

However, in general, earth-level heavenly materials and earth treasures are the minimum requirements for immortal cultivators to refine magic weapons, which not only contain spiritual energy, but also have unique rules that can help monks participate in the path of enlightenment. And in most cases, only after the Jindan period has the concept of natal magic weapons, after a foundation building period monk gets the magic weapon, although its power is similar to that of getting a superb spiritual weapon, it is also difficult to reach the strength of the Jindan stage.

It's a pity that after millions of years of mining in the Immortal Cultivation Realm, the Heavenly Materials and Earth Treasures that can refine magic weapons are already very rare, after all, where are there so many Heavenly Materials and Earth Treasures that can be used by immortal cultivators? For example, in a large Purple Gold Spirit Copper Mine, only its mother Purple Gold Copper Mother is the material suitable for refining magic weapons, and after taking it, this vein will not continue to grow, nor will a new mother be born again.

Therefore, after the unrestrained exploitation of the predecessors, there are now fewer and fewer earth-level heavenly materials and earth treasures that can be directly refined into magic weapons, and every time they appear, they will attract a large number of Jindan period monks to compete for them, and finally there are only a few who can refine the earth-level heavenly materials and earth treasures into this life magic weapon.

You must know that not all heavenly and earthly treasures are suitable for refining magic weapons, and many of them exist in the form of elixirs, which also have a great effect on immortal cultivators.

However, immortal cultivators are naturally not willing to do this, with the temperament of immortal cultivators, they naturally try their best to replace things, this is the prototype of the refiner, and after years of research, one of the most successful substitutes is the demon beast Neidan.

The demon beast inner pill can be said to be very close to the existence of earth-level heavenly and earthly treasures, and the natal spells contained in it are also almost like the Tao, and the immortal cultivators use the demon beast inner pill to refine the corresponding parts of this demon beast, and finally refine the magic weapon, which meets the needs of most of the Jindan monks in the immortal cultivation world today.

It's just that the inner pill that can refine magic weapons also requires at least a seventh-order demon beast, and since there is only one inner pill, a seventh-order demon beast can only refine one magic weapon. But the seventh-order demon beasts are not cabbages, they are almost already considered members of the demon clan when they open their spiritual intelligence, and the wanton slaughter of the human race will naturally attract the demon clan to resist, which has caused one of the biggest contradictions between the human race and the demon race.

Not only that, except for those top demon beast inner pills, most of the magic weapons refined with demon beast inner pills are difficult to compare with the magic weapons refined with heavenly and earth treasures, especially in terms of enlightenment, the magic weapons of demon beasts are far from the same, so immortal cultivators also divide the magic weapons into four levels:

Among them, the magic weapons refined by the seventh, eighth, and ninth order demon beasts in the inner pill correspond to the lower, middle, and upper levels respectively, and the magic weapons refined with the heavenly and earthly treasures or the magic weapons refined by the demon beasts above the tenth order are the best magic weapons, which can assist the master in enlightenment.

The power and magic of the magic weapon increases with the level, but there is no absolute, because the natal magic weapon and the master's cultivation grow together, so in the hands of the master, the natal magic weapon can often exert a higher level of strength, if you spend more energy on the natal magic weapon, the power may be even greater.

Improper maintenance or other accidents of the magic weapon may also fall to the grade, some magic weapons refined by some special means or extreme human-level natural materials and earth treasures, the power can also reach the point of medium and upper grade magic weapons.

Among all the magic weapons that Zhang Zhiping has seen, most of them are middle-grade magic weapons, the heavy sea hammer, the mountain ruler and the lotus platform he often uses to meditate belong to the high-grade magic weapon, which seems to be refined in the prototype of the heavenly and earthly treasures;

There are only two of the best magic weapons that he has really seen and are of good quality, the first is the Zhenhai Zhong of the Yuanyu Daoist, when he almost reversed the disadvantage of Turtle Island with the strength of one person, although there are also some coincidences, but it is also an indisputable fact that the power of one person chases the second and they fight.

And the second is the empty net he got from the empty Luozi, how powerful the mountain ruler was at the beginning, but it is still difficult to break free from the shackles of the empty net, which contains a certain space mystery, but it is a pity that this magic weapon is only an auxiliary magic weapon, and does not meet Zhang Zhiping's requirements.

What Zhang Zhiping hopes for now is to find an automatic defense magic weapon above the top grade, otherwise like his meditation lotus platform, although it is barely a defensive magic weapon, he can hardly play much role, and it is very inconvenient to use.

Therefore, he kept rummaging through the list of treasures along this line of thought, and I have to say that the treasures that appeared in this trade fair are really extraordinary, elixirs, magic weapons, exercise cheats, rare beasts, etc., which can be said to be everything, among which there are seven earth-level heavenly and earthly treasures, both elixir and spiritual materials, which can be said to be cherished to the extreme.

Zhang Zhiping couldn't help but pay attention to this, among them, there were three pieces of elixir, namely Liuguang Pure Soul Flower, Nine Aperture Dragon Fruit and Sanyuan Pei Infant Grass, and four pieces of spiritual materials, namely Golden Light Flame Sun Stone, Empty Silk Tianyin Bamboo, Deep Sea Dark Sinking Gold and Floating Light Thousand Layer Cloud.

It seems that seven heavenly and earthly treasures have appeared all at once, but this is almost the only heavenly and earthly treasures left in the Lingyuan Realm for thousands of years, plus there are a large number of other monks from the Immortal Cultivation Realm who are here, which makes so many treasures appear at this fair.
