As for the highest level of first-class heaven and earth aura, it is usually impossible to see, the cave heaven blessed land of the hidden world sect or the treasure land of the cultivation of immortals, usually the first-class heaven and earth aura will appear, and the first-class heaven and earth aura, if it is used for cultivation, as long as the talent can reach the best, in the environment of the first-class heaven and earth aura, it only takes more than a month to be able to build a foundation, and it will definitely be able to form a golden pill within three years, and it will definitely be able to condense the primordial infant within 20 years.

And this is also talking about the talented, if it is the kind of talent that has reached the immortal posture, it will not take a few years to be able to directly reach the Yuan Infant Period, and it will take more than a hundred years to be able to Yuan Shen, of course, the first-class heaven and earth aura is extremely rare, even Zhou Ran has never seen a place with a first-class heaven and earth aura in his previous life, but he has heard some similar rumors.

Having said that, he was worried that this Zhongpin Lingzhu would not be found. The main reason is because of the Hong-level Qi Gathering Talisman, all the absorption is the fourth-class heaven and earth aura, and the low-grade spirit bamboo is also enough, and it is definitely useless to put it in the hands of high-level cultivators, but for those practitioners who practice Qi or build a foundation, it should be barely a good material, don't think that the level of the death game for the material evaluation is low, it really means that this material is useless, in fact, there are quite a few materials that can be used to refine magic weapons, most of them are Hong-level evaluations, For example, the very common dark iron.

Xuantie is considered to be an extremely standard civilian material, the vast majority of low-level casual cultivators, or some third-rate sect disciples, when refining their first magic weapon, they generally use Xuantie, after all, the only drawback of this material is that it is heavy, in addition to the same level, the magic weapon he refined has good attack power, the defense is acceptable, and the speed is okay, and at the same time, there is no need to spend a lot of money to abandon him to choose other materials.

And at the moment, this is not comparable to the lower grade spirit bamboo if it is only in terms of attack, but if you talk about the comprehensive attribute value, especially for the conduction speed of heaven and earth aura, as well as the conduction speed of different attributes, then compared to the dark iron must be much stronger, there are two reasons why the ice attribute spirit ink was chosen, the first reason is that the runes with elemental attributes that he can depict on the bamboo now are nothing more than ice and thunder.

And the thunder attribute treasure, he already has the Kui Niu Bracer, the Kui Niu Bracer is a celestial-level treasure, the power of the thunder and lightning that can be released, even if it is the power of the thunder attribute magic weapon refined by this low-grade spirit bamboo, it is estimated that it is weaker, but the ice attribute is different, he does not have a relatively strong ice attribute attack trick now, and even his internal qi about the frost attribute is only to comprehend the most basic ice characteristics.

And when he was observing this spirit bamboo just now, he also tried to inject some ice attribute internal qi, and the surface of the spirit bamboo did not show any frost, but was shrouded in a layer of white cold matter, which obviously had a very good conductivity and affinity for the ice attribute, so after thinking about it, he finally chose to depict the ice attribute runes upward.

In fact, theoretically, the runes of the wood attribute must be the best choice, but in the death game, the 5 lines of runes of gold, wood, water, fire and earth are at the back of the basic runes, and among the basic charms he has now obtained, although there is such a fire spell in the three attribute charms, but if this fire spell is really calculated, it should belong to the derivative attribute of fire, and it is not really the fire that belongs to the five elements, but unfortunately he has never been exposed to the 5 elements of the charm, Therefore, the runes of the wood attribute are not mastered.

After picking up the pen, dipped a little ice attribute of spiritual ink, Zhou Ran put his hand on the qi gathering talisman, wanting to draw a wisp of heaven and earth aura out, but after thinking about it, he didn't do it, but picked up another bamboo slice, and began to depict the ice spell on it, the most basic ice spell, at this time Zhou Ran has mastered almost, after depicting one on this bamboo piece, he picked up another bamboo piece, and depicted more than a dozen bamboo pieces in a row, all the ice spells on it were done in one go, and there was no failure in the middle, Zhou Ran slowly breathed a sigh of relief,

Don't think he's exaggerating too much, after all, this spiritual bamboo can be evaluated as a Hong-level material, and it is infinitely close to the material of the Celestial level, it is estimated that for a very long time, he will not be able to find such a good material, in fact, the Hong-level material, and even the same level of material as the spiritual bamboo, there is not nothing in his warehouse, but those materials are not metal, or what kind of animal skin and animal bones are not suitable for refining into magic weapons.

He took another piece of bamboo, depicted a few sword talismans and iron armor spells on it, and after making sure that there was no problem, he finally picked up this spiritual bamboo, accounting for the spiritual ink of the ice attribute, and first introduced a wisp of heaven and earth aura into it, although it was only the lowest level of aura, but when it was injected into the brush in his hand, the layer of ice blue light shrouded in the tip of the pen became brighter and brighter.

Anyway, the Qi Gathering Talisman is placed here, after all, it is able to absorb a sufficient amount of Heaven and Earth Aura, and after the Heaven and Earth Aura, it is also for use, so Zhou Ran used it without hesitation, when he depicted the first stroke, the tip of the pen had touched the surface of the spirit bamboo, he originally planned to use the first rune to depict the ice spell, and then add the sword talisman or part of the rune of the iron armor spell to the second or third rune, Used to forge a magic weapon that can release ice weapons as he first thought,

But after thinking about it left and right, this possibility is really not very large, it is better to refine this thing into a prop similar to the one he refined before, which can absorb the aura of heaven and earth by himself, and then release one of the attributes, if this kind of prop is really calculated, the power is definitely not as strong as the quasi-magic weapon that is close to the magic weapon in his own conception, but the difficulty of refining is low, and more importantly, the success rate is higher, the refining method of this quasi-magic weapon he conceived before has been tried more than a dozen times without successAlthough a considerable part of the reason is because the substrate is not good, that is, the quality of the bamboo used is not good, it is inevitable that there are certain problems in its initial conception.

The spirit bamboo was not easy to come by, Zhou Ran finally picked up the brush and drew a circle, as the first rune, just after the depiction was completed, the white light around the spirit bamboo became softer, he already felt that this spirit bamboo began to slowly absorb the aura of heaven and earth, which had never been done before, even if he was refining those props before, there would be no such situation after depicting the first rune, and sure enough, it was because there was a certain amount of spiritual power stored in this spirit bamboo,

The reason why it is suitable for refining magic weapons is because of this reason, you must know that those magic weapons that have no spiritual power themselves, even if they draw dozens or even hundreds of runes that can absorb and store spiritual energy, but they must be completely drawn before he can start to absorb and expound spiritual energy, which indirectly causes the quality of these magic weapons to be lower, if it seems that it should be okay at present, and then Zhou Ran depicted the first and second runes of the ice spell on it, Since the Ice Spell can only be combined by three runes, after depicting the first and second runes, nothing else has happened.

Then Zhou Ran fell into thinking, and the next description he can carry out is divided into two kinds, the first is to depict the rune of the sword talisman on it, at present, if the second rune of the sword talisman is depicted, it will release its ability, and it will be bound into a more regular one, the attack range will be greatly reduced, but the strength will be increased, of course, there is another way, that is, to depict the rune of the iron armor spell, and in the process of many previous attempts, The runes of the Iron Armor Spell also have the experience of successfully depicting once or twice, probably because of the low quality of the bamboo used before, so even if the rune of the Iron Armor Spell is depicted upwards and successfully, but after the depiction is completed, it can only become an alternative rune.

Those props can release a very powerful energy impact, and it is different from the original form of the spell, they will release a fan-shaped impact, the impact range of this fan-shaped impact, about the maximum can be expanded to a maximum angle of 120 degrees, the distance is almost 5 meters to 6 meters, and the energy released by the fan impact is related to the attribute spell depicted, but with the rune depicting the sword rune, the difference is that this rune depicting the iron armor spell can release the props of the fan impact, which can only be used once, No matter how much internal qi is injected, or if it depicts a rune on it that can absorb the aura of heaven and earth, it can only be used once.

'What to do?' Single-use items or reusable treasures? Zhou Ran fell into thinking, but as he thought about it, the light of the three runes that had been depicted began to gradually become condensed, Zhou Ran hurriedly came back to his senses, these three runes obviously absorbed too much heaven and earth aura, if he didn't quickly make up his mind to draw the next rune, then after the three runes were completely condensed, she would have no chance.

Zhou Ran gritted his teeth, anyway, this is just an attempt, this spirit bamboo can be called relatively valuable, but it has not yet reached the situation where he can't get it, so he neatly depicted the second rune of an iron armor spell on it.
