Compared to carving runes on ordinary bamboo, it is actually more troublesome to depict runes on such a higher-grade material, and simply dipped a pen in ink to draw runes on it will not have any effect.

To put it simply, it is not considered to be a depiction of runes on this kind of high-level item, to be precise, it is carved and painted, and it has to be successfully printed into it by the method of engraving, and the difficulty is one or two grades higher than that of depiction, if it is not for Zhou Ran's success in obtaining the talent related to runes, and this talent level is quite high, I am afraid that he will not be able to integrate the runes into it in a way such as carving, then this item is, in a sense, even if it is scrapped, At least for quite some time, it didn't work as well as it should.

You must know that although this Wai Dan is only at the Celestial level from the level of view, it is definitely the top item in the Celestial level, in terms of the various props that Zhou Ran has harvested during this time, I am afraid there are not too many that can be compared with it, you must know that in the grade grading of the Qi Refining Era, the Qi Refining Period belongs to the Celestial level, and the Jindan period of the foundation building period and the Yuan Infant period of higher levels belong to the Yu level, according to the concept of a very famous one in the death game, the item is classified as a level, The items in the foundation building period theoretically correspond to a slightly lower level of the Celestial Rank, so this item can already be regarded as the highest level of the Celestial Outer Dan.

The old man's understanding of the Wai Dan technique is not very profound, and 90% of the items he can refine depend on the medicine furnace made by Zhou Ran, yes, it is the bronze medicine furnace he built, which is actually the part that plays the most role in this refining process, and the remaining success rate, there is still a part occupied by materials, and the role that the old man really plays is actually relatively small, so in this case, he can refine such a celestial-level Wai Dan, It's basically the limit of the old man, and if he wants to refine a more advanced one, he can be regarded as powerless.

Thinking of this, the old man looked at this Feng Wai Dan floating in mid-air, and his face showed some helplessness, although this Feng Wai Dan can provide him with a considerable degree of combat power, but I am afraid that he can only use this Wai Dan for a long time, after picking up a short knife and smearing a layer of spiritual ink on it, he used his pen to write three runes of Qi Gathering Talisman on the back of the knife.

Slowly exhaled a long breath, and then put the tip of the knife against the Waidan, a small rune has already appeared on the surface of the Waidan, that's right, carving, although it sounds like it is going to use some kind of sharp carving knife or something like that, leaving traces on this Waidan, but in fact it is not that complicated, the whole process is still more immortal cultivation or more mysterious, the correct way is actually to use something similar to this sharpness as a medium, and then leave spiritual ink on it, As the main carrier suitable for integrating the power of runes, and finally input your own spiritual power or energy such as internal qi into this medium to activate these carriers, and successfully engrave the charm on it, the part that really needs to be done is actually very few, or even none.

Looking at the runes that appeared on it, Zhou Ran slowly breathed a sigh of relief, the most basic runes have been carved, and there are no problems, the first rune he carved on it doesn't need to think about it, it is naturally the rune of the Qi Gathering Rune, in fact, most of the treasures need similar runes, maybe the runes they use are higher than the runes of the Qi Gathering Runes, but there is no difference in nature, the main thing is that the energy consumed by this type of props is too much, and the reason why they can use it normally, It's not that the user is constantly instilling power, in that case, even a true immortal may be difficult to do, in most cases, the energy of the magic weapon will slowly recover by itself, and the reason for this slow recovery speed is mainly related to the runes depicted on them.

High-level Qi Gathering Rune type runes can greatly increase the speed of their absorption of aura and transformation of aura, this Wai Dan is one of the main methods for the old man to fight in the future, if he simply releases two spells in the process of fighting, there is no way to continue fighting, then I am afraid that the old man will also feel a little embarrassed.

And it's not just this rune, then Zhou Ran carved 5 runes in a row, adding up to a total of 6 runes of Qi Gathering Talismans, which are depicted on the top of this Wai Dan, with the rune bonus of 6 Qi Gathering Talismans, Lao Bai put his hand on the top of this Wai Dan, felt it for a while, and then nodded slightly and said: "The effect is not bad, with so many bonuses, the recovery speed of its internal qi has increased by about 40%, which is quite faster than at the beginning, and the more important thing is not this 40% Rather, it may have roughly doubled the amount of aura stored there, which is the most important thing. ”

The recovery speed of the aura, which is the so-called recovery speed of the blue bar, is actually not too effective sometimes, because like most secret realms or dungeons, it is likely that there will be no aura, and when fighting in such a situation, what is consumed is the energy stored in this outer pill, and the more energy stored in the outer pill, the slower the consumption will definitely be,

It is precisely because of this thought that Zhou Ran put the main aspects of this carved rune on this, after completing this thing, Zhou Ran began to touch his chin and think, just like he just discussed with the old man, the attribute spell must be depicted, as for which fire spell or ice spell to choose, this will not be talked about for the time being, anyway, the thunder spell must be engraved, and the runes of the thunder spell were engraved in one breath, and Zhou Ran was also a little relieved.

I saw that Zhou Ran had just stopped his movements, and then picked up the short knife in his hand, and there was already a crackling thunder and lightning on the top of the Waidan, but these thunderbolts only flickered slightly, and then gradually dissipated, after all, the main attribute of this Wai Dan is the wind attribute rather than the thunder attribute, and the two thunder lights that came out just now are still because the runes have just been carved and completed, and they are not completely integrated with this Wai Dan, plus the aura in the Wai Dan is very sufficient, so a little spell is properly activated, The power inside will cause such a lightning flash.

Even if you really want to choose to engrave another attribute talisman, there are still many places left to engrave the seal, even if you add the golden light talisman and the sword talisman, so Zhou Ran turned his head to look at the old man.
