Considering that the Shenluo River and the Shenluo Kingdom were above his head, Zhou Yue arranged several Pure Land spells in the underground dark river to ensure that his alchemy here would not affect the lives of mortals.

The vast majority of the mortal realms in the cultivation world have the shadows of the major sects behind them, and a small number of them are simply ruled by monks, although these large and small forces in the Northern Yan Department have been fighting endlessly all year round, they also know that mortals are the foundation of the cultivation world, so they usually seek a dangerous place and no one to fight, and will never disturb the life of the mortal realm.

In this case, if Zhou Yue indiscriminately refining the pill caused problems in Shen Luo Kingdom, then the sect behind Shen Luo Kingdom would definitely find him out, and Zhou Yue didn't intend to cause this trouble, so he was completely prepared.

Placing the Pure Land spells in layers, any true qi fluctuations will be calmed down as much as possible when passing through the Pure Land spells, and after passing through multiple Pure Land spells, they will be eliminated invisibly, and Zhou Yue has arranged two layers of Pure Land spells near the underground dark river, so that even if the two great powers of the Shattered Destruction Realm fight in the dark river, there will not be any trace of true qi fluctuations leaking out, Zhou Yue believes that the movement of refining a pill will not be as big as the battle between two Shattered Annihilation Realm monks.

After making the preliminary preparations, Zhou Yue sat cross-legged in the Heavenly Treasures and began to think about the materials needed to refine the Ice Tree Heart and the possible techniques.

"You need fuel powder here, right?" the bell let out his true qi and poked at the pile of red powder beside Zhou Yue, and said, "The weak fire and strong wood attribute can just be added without harming the medicinal properties of the ice tree heart. ”

"Hmm...... However, I feel that the medicinal power of the fuel powder is a bit too strong, and it may react with other excipients to produce some unpredictable changes. Zhou Yue thought about it again and again, and finally summed up the pile of crimson powder to his right hand - here is the selected heaven and earth treasure.

From the beginning of entering the underground dark river, Zhou Yue has been discussing with the bell for nearly two hours, and the selection of materials is the most critical step when creating his own elixir, and the reason why it takes several days to refine is precisely because it takes a lot of time to screen the heavenly materials and earth treasures required for refining, as for the real furnace alchemy, I am afraid it will be over in just one hour.

The heavenly materials and earth treasures purchased by Zhou Yue along the way before are only the excipients that may be used, and they are not poured into Zewangding to refine the elixir, what to use and how much to use, these are the main problems that plague Zhou Yue.

Like this red powder that Zhou Yue had at hand, called Burning Powder, it is a root attachment of a special heaven and earth treasure, a neutralizer with weak fire and strong wood attributes, and is theoretically the most suitable for use when refining the heart of the ice tree.

However, Zhou Yue must take into account the problem that fuel powder can also be used as the main material, because the medicinal power of this material is amazingly powerful, Zhou Yue must carefully adjust the dosage to prevent the fuel powder from combining with other excipients and other auxiliary materials to have adverse consequences.

Time passed slowly in the discussion between Zhou Yue and Bell, although the difficulty of Zhou Yue's self-created pill this time was not small, he also had an advantage over ordinary alchemists, because he also had Bell by his side, a person whose Dan Dao level was not inferior to him, to help check and fill in the gaps, so that the possibility of Zhou Yue making mistakes would also be greatly reduced.

Different from the calmness of ordinary sect alchemists when they created their own elixir, Zhou Yue did not allow any mistakes in this alchemy, because he only had such an ice tree heart in his hand, in case the refining failed, he would not be able to find another heaven and earth treasure with a similar effect, if he was not completely sure, Zhou Yue would rather swallow the ice tree heart directly to improve his cultivation.

......

......

"That should do. ”

Zhou Yue breathed a long sigh of relief, and when he finally prepared for refining with the bell, two days had passed since he first dived into the dark river, and Zhou Yue did not stay in place to think about it in the past two days, but conveniently arranged this underground dark river into his own temporary cave mansion, at this moment, this temporary water mansion probably only lacked a formation to cover his aura and protect against the attacks of external forces, which could be compared with the cave mansions provided by the major sects to the cultivators of the Shattered Destruction Realm.

"Why don't you try refining the excipients first?" The bell used his true qi to lift several heavenly and earthly treasures around Zhou Yue, and said with some confusion: "These excipients are not so easy to deal with, and many of the excipients used in your pill can be used as the main ingredients." ”

Because Zhou Yue didn't have the financial resources and energy to test all kinds of auxiliary materials one by one, he had to choose some common main ingredients to serve as the auxiliary materials for the Ice Tree Heart, which was also a common problem encountered by Dan Xiu above the Shattered Annihilation Realm.

The materials above the shattered realm are already scarce, and there are very few matching excipients of the same level, so I have to choose some main ingredients of the pill as a substitute.

However, the reason why the main ingredient is the main ingredient is because these natural materials and earth treasures can be fused with a variety of materials, and they contain powerful medicinal power.

Knowing the nature of each material used in the pill recipe is only the most basic basic skill, and there are by no means a few problems that give alchemists a headache, which is also one of the reasons why alchemists above the Shattered Destruction Realm are so rare.

Zhou Yue pondered for a moment, took several accessories selected by the bell with his true qi and put them into Zewang Ding, and with a flick of his fingers, a wisp of Dan Fire suddenly appeared at the bottom of Zewang Ding, and began to scorch several accessories in the Ding's body.

Because the auxiliary materials selected this time actually have the strength and characteristics of the main materials, Zhou Yue did not dare to refine them in the palm of his hand, but honestly used Ze Wang Ding to deal with them.

It can be said that Zhou Yue has already used these auxiliary materials as the main ingredients to refine, at this time, he is equivalent to refining more than ten different pills in a pill at the same time, and he also has to ensure that these dozen or so pills do not conflict and finally merge.

"Boom!"

The burning of the Dan Fire only lasted for a few breaths, and Zhou Yue clearly sensed the powerful medicinal power, which was dormant in Zewang Ding, and could erupt at any time, and the power was definitely no less than the self-explosion of several Shattered Annihilation Realm monks.

Zhou Yue couldn't help but shake his head, if he could absorb all this power, he would probably have already broken through to the late stage of the Shattered Annihilation Realm at this time, but it was not so easy for the monk's cultivation to break through, just infusing the true qi would only blow up the monk's dantian, so this was the birth of the elixir that improved his cultivation.

The refining pill did not have such a powerful power, so Zhou Yue had to continue to release the power of Zewang Ding on the premise of ensuring that the medicinal power did not explode, until the remaining medicinal power was fused together and precipitated, and this first step in refining the auxiliary materials could be regarded as a success.

Zhou Yue pinched the trick with both hands, and casually punched two magic seals towards Zewang Ding, and a dense layer of true qi suddenly appeared on the surface of Zewang Ding, which was used to isolate the surging true qi in the ding.

"Definitely!"

Zhou Yue drank softly, bent his fingers and popped out a few magic seals again, and then used his true qi to stick his right palm on top of Ze Wang Ding-

"Boom!"

The strange dark blue flame erupted instantly, the Dan fire in Ze Wang Ding's Ding dimmed, and the Hell Fire released by Zhou Yue instantly ignited the extremely powerful medicinal power in the Ding's body!

"Bang!"

Ze Wang Ding trembled violently, but Zhou Yue repeatedly punched out countless magic seals with both hands, and slapped his palm on top of the ding's body, and a layer of dark blue flames suddenly wrapped in a large amount of medicinal power revealed Ze Wang Ding, slowly dissipating between heaven and earth.

The main purpose of this process is to reduce the unstable medicinal power in Zewang Ding, and leave the stable fusion medicinal power in the medicinal liquid, the practice of ordinary alchemists should be to open a small opening and then fight against the rampaging medicinal power, but with the power of the Shattered Annihilation Realm cultivator to control a medicinal power far beyond the Shattered Annihilation Realm is tantamount to sailing in the angry sea, and a large part of the alchemists are falling on the increasingly difficult to control the medicinal power.

However, Zhou Yue naturally didn't need to be so troublesome, he came up with an excellent way to reduce the power of the medicine from the beginning, and that was to use Honghu's natural supernatural power 'Cold Hell Fire'.

The ability of the Hell Fire is to incinerate the True Qi, and this incineration is very stable and fast, the incinerated True Qi will not explode, and will be burned by the Hell Fire in a short time, which can just be used to use the excess medicinal power, because the medicinal power of the Heavenly Treasure is also a special True Qi in essence.

Zhou Yue didn't relax a bit, the sweat droplets of beans slipped from the corners of his forehead, but he didn't care about wiping them, but the magic seal on his hand changed, and once again guided the excess medicinal power to the vicinity of Zewang Ding's Ding Wall, and then repeated the old trick, using the Cold Hell Fire to incinerate the medicinal power.

After repeating it dozens of times, the medicinal liquid in Zewang Ding has completely stabilized, and the originally chaotic medicinal liquid has become a crystal clear golden thick liquid at this time, and a strange fragrance comes out of Zewang Ding, filling the entire underground dark river.

However, because of the layers of Pure Land spells near the underground river, these aromas will not overflow beyond the underground river, nor will they attract any curious demons and monks.

Zhou Yue took a deep breath, let the medicinal fragrance fill his lungs, and when he stabilized his emotions, Zhou Yue's hands immediately intertwined a series of magic seals in the air, and slowly took out the medicinal liquid in Zewang Ding.

"Snort...... Sneer......"

The golden liquid medicine floated out of Ze Wang Ding under the support of the law seal, Zhou Yue saw the opportunity, immediately took out a jade bottle from his arms, and inhaled the golden medicine into the jade bottle, until the jade bottle stabilized, Zhou Yue breathed a sigh of relief.

In this way, the refining of the first excipient has come to a certain end, and then there are two different excipient liquids to be refined, and after all the three medicinal liquids are refined, Zhou Yue will start to refine the most important main ingredient in this elixir-

Ice Tree Heart. (To be continued.) )
