The old man fanned the fan in his hand, and looked at the pill furnace in front of him boredly, he had spent more than half a month refining this outer pill, during which countless precious metals were added to it, although it was said that there was nothing too high-grade to be found in the primordial era, but all the metals that had a little effect were all stuffed to the old man by Zhou Ran.

And the old man can't throw all these things in, different attributes and different characteristics of things are mixed together, it is very important to pay attention to the proportion, if it is a relative attribute or obviously not matched characteristics put together, then the best result of the last Wai Dan is to refine a very poor attribute of the Wai Dan, luck but almost scrapped on the spot, so in this case, the old man has been carefully selected, whether it is a low level, the attributes do not match, Or other metals for various reasons, all of which were thrown aside by him, and finally the 6 metals he carefully selected,

In addition to these 6 kinds of metals, there are a small number of different kinds of minerals and other materials, not all of which can be refined using metals, a perfect Waidan, the appropriate use of some other materials, for the results of the Wai Dan also has a very good help, because there is an additional wind stele, so in the selection of materials, the old man mainly chose the wind attribute, if the wind attribute is used directly, in fact, it is not so bad, but the characteristics are relatively poor, That is, when using breeze and breeze, the strength of all kinds of aspects is relatively weak, the attack power is not as good as other attributes, and the defense power is also biased, but compared to other attributes, the wind attribute and the water attribute are a little similar, that is, he has quite good auxiliary abilities at the same time, in addition to attack and defense, it can also be used to accelerate and slow down, and even heal injuries to some extent, its effect is certainly not as good as the light attribute and water attribute, but it is also quite good,

Especially now in the territory, there are different kinds of attribute spells refined by Zhou Ran, and the three attribute charms can be used together with the wind attribute, and it can strengthen its attack ability to a certain extent, so the old man who thinks of this will naturally choose his attribute as the wind attribute, in addition to the wind attribute, he also used the metal ore that Zhou Ran took out from the Heavenly Demon Fantasy Realm, and added a little magic attribute to it, if the natural attribute, the old man didn't think about it,

At this time, the blazing blue flames burning around this pill furnace had begun to become a little weaker, and for more than half a month, even if different kinds of metals were added to it one after another, and the time for its refining success was delayed again and again, but after such a long time, this outer pill was basically about to succeed.

The old man took a deep breath, his face was full of nervousness, to be honest, this was the first time he had refined the Wai Dan, to be precise, it was the first time he had successfully refined a Wai Dan, he had tried it before, although all those memories were instilled in him by the death game, but it was also equivalent to his real experience, and in these memories, he did not succeed in refining any Wai Dan, the Wai Dan is not a very low-level thing, on the contrary, even in the era of Qi refining, The Outer Dan Technique can barely be regarded as a relatively high-end thing, with the strength of the old man, he can already be considered lucky to be able to successfully touch such a thing as the Outer Dan Technique, and if he wants to successfully refine a few, the possibility of being able to successfully refine a few is really not very likely in the Beacon Era.

At this time, Zhou Ran was also standing behind the old man, originally he was studying the metal taken out of the Heavenly Demon Fantasy Realm, to see if he could try to create a few pieces of equipment with demon attributes, and then to strengthen the combat effectiveness of the generals in his territory, but after learning that the elixir on the old man's side was about to be baked, he still took the lead in coming to the old man's side, after all, he had never seen Waidan, and he must be very curious

The old man slowly put down the fan in his hand, he raised his hands, and saw that the two hands were shrouded in a dark cyan airflow, which was exactly the performance of his neutral internal qi after transforming it into the wind attribute, compared to Zhou Ran, the old man with the sleeping magic skill of neutral internal qi, has been studying this magic skill for more than ten years, all kinds of characteristics, it also has a lot of mastery, like Zhou Ran, who is lucky enough to master a large number of characteristics, and he can't compare with him at all, The characteristics of the wind attribute are one of the most common, and the old man can naturally use it casually.

And it's not just an ordinary breeze or a breeze, even storms, whirlwinds and even other wind attributes of higher grades, it can be used, but the level of this Wai Dan itself is too low, and the special sex of a higher level is whether the old man can use it, I'm afraid that the Wai Dan itself can't bear it, so in this case, even if this is taken into account, the old man didn't use the characteristics of a higher level, he just put the two cyan air currents in his hand next to the medicine furnace, Then he slowly closed his eyes, only to see that these two cyan air currents transformed into two shapes like writhing spirit snakes, and poured into the medicine furnace.

Feeling his rapid consumption of internal qi, the old man's face showed a little joyful look, he is not afraid that the internal qi is consumed too quickly, he is afraid that the internal qi will not be consumed, if the internal qi is not consumed, then the problem is serious, then it proves that the refining of this outer pill has failed, but now the internal qi is still in a state of consumption, which made him breathe a little relieved, and soon the old man felt the pill in the medicine furnace, and there was a vague feeling, which made him nod slightly, Although the heat is still a little worse, but now this Wai Dan can actually be baked, but the old man does not plan to let him come out so quickly, but is still quietly waiting.

Sure enough, it didn't last too long, the edge of the medicine furnace immediately began, and a cyan air flow gushed out, and a breeze was also around, the old man slowly exhaled a long breath, with a relaxed smile on his face, good guy, there shouldn't be any big problem if you look at it now, these cyan air currents began to flow rapidly, and the four sides of the medicine furnace also emitted a dazzling cyan light, Zhou Ran took a step back slightly, this cyan light carried a rather not weak wind power, It seems that the old man's refining of this Wai Dan is more successful than he imagined.

Just when Zhou Ran was about to ask, when will this pill be completely successful, I saw that this cyan light suddenly burst out, and the lid on the top of the medicine furnace was directly flown out, this cover was completely forged from bronze, and the area was not stingy, the weight may be about 15 catties to 20 catties, but it flew out directly, and even sank deep into the wall on the side,
