There were bursts of beast roars in the valley, but judging from the momentum, they were all relatively weak, and it was very likely that after the people of the Cao family discovered this place, they let the powerful cultivators personally come to deter the powerful demon beasts here, and even those demon beasts have all become a rich cultivation resource of the Cao family.

And sending Cao Jinting and others over, I think it was to prepare to mine the small metacrystalline veins under these five peaks.

Chu Yu carefully observed the surrounding environment of the valley, and after wandering around, he found that there were many beast caves on a mountain peak in the inner valley, which had become abandoned caves at this time.

The medicinal herbs in the valley have been picked for a little year, not to mention some exotic flowers and fruits and other essences of heaven and earth, the only thing that is still a little valuable is that the vitality here is rich, and the valley is close to the small yuan crystal vein, which is a very good cultivation occasion for Chu Yu at the moment.

After thinking about it for a long time, Chu Yu finally decided to find a beast cave, expand it, and then arrange a set of hidden defensive formations inside, although due to the limited cultivation, the level of the formation is not very high, but for the martial artists of the Holy Elephant Realm cultivation, it is difficult to find even if they are close.

The beast cave was re-expanded and changed to a cave with a depth of five or six meters, Chu Yu took out the things prepared, and at the same time scattered a lot of medium-grade yuan spars in the cave, and arranged a gossip gathering yuan array, after a while, the vitality in the cave became more and more intense, after all, the distance below this mountain peak is not deep is a small yuan spar vein.

After everything was ready, Chu Yu took out all the medicinal materials and fierce beast essence blood that had been prepared to quench the body and fuse the divine soul.

In order to complete this process, it is necessary to first fuse the essence of the medicinal materials and some heaven and earth exotic fruits, refine them into a whole body pill, and then cooperate with the thirty-six kinds of fierce beast essence blood to completely control this body, and the soul and body have reached the point of perfect integration.

When he was in Jubaolou, he bought some materials for refining pills, several large water tanks, one large and one small.

For the all-body pill, it can only be regarded as a low-level special pill, ordinary cultivators can hardly use it, even if they are gifted cultivation geniuses, they will not use this all-body pill, only cultivators who take away or reshape their physical bodies on the edge of life and death will use this all-body pill to carry out this step of fusion cultivation.

However, this kind of all-body pill refining technique, after all, is almost useless, I am afraid that many families do not have it, and some sects believe that it may not be perfectly preserved.

With his current cultivation, he was not yet able to communicate the energy of heaven and earth to generate flames, so he purchased a kind of burning wood, which, combined with lava stones, could produce a kind of flame that cultivators used by martial artists to refine the pill basically.

The ordinary firewood heat is difficult to control, and only the burning wood and lava stone can easily control the change of the fire.

Refining pills, no matter what level of pill masters are, they all deeply agree that mastering the most essential alchemy secret skills of fire is that many high-quality pills can only be achieved by relying on the rich experience of the refining person and the control of the fire.

Chu Yu refined the pill for the first time after his rebirth, and it was also a very important all-body pill, so he was very cautious, and after checking the materials needed, he then held his mind and adjusted his state to the peak.

Before that, he took out a kind of soul gathering wood and wore it on his chest, which was a kind of alien wood to enhance his spirit.

Half an hour later, Chu Yu began to ignite the burning wood and lava stones, and the crimson flames shone brightly, illuminating the cave even brighter.

He washed Xiao Ding again, and then simply refined two furnaces of blood qi pills, on the one hand, to observe the changes in the fire, on the other hand, to observe the heat of Xiao Ding, in short, this link is very important, he attaches great importance to it, and the results of the two furnaces of pills are quite satisfactory.

After some contemplation and summarization, his expression perked up, and he began to refine the pill, putting in the medicinal materials in order and rhythmically, adding some beast blood essence from time to time, as well as some exotic fruits.

After a while, more than a dozen medicinal materials and six or seven kinds of fierce beast essence blood had been added to Xiao Ding, as he continued to control the heat and slowly concentrate the medicinal liquid, he thought about it, in order to increase the effect of the whole body pill, he gritted his teeth and put in a heavenly fairy fruit.

The Heavenly Immortal Fruit was snatched from the hands of the three family holy sons in the Qilin Cave Valley of the small interface, and since he got the nine, he hadn't had time to deal with it.

Containing surging vitality energy and vitality, after adding, the liquid medicine suddenly boiled, and a surging energy filled the entire Xiaoding.

At this moment, Chu Yu was pleasantly surprised to find that the energy contained in those medicinal liquids and beast blood essences was completely stimulated, and they quickly fused with each other.

Although Chu Yu knew that adding the Heavenly Immortal Fruit would have a miraculous effect, he didn't expect such a good reaction, he hurriedly gathered his mind, mastered the temperature of the flame, and slowly solidified the medicinal liquid.

More than a dozen energy currents in Xiao Ding slowly surged up like a vortex, and the internal strength cultivation method of the Heaven Swallowing Recipe caused the exercises he ran to be very similar to the Heaven Swallowing Technique, and in the slow solidification process, Chu Yu was cautious, for fear that there would be a situation in the explosion furnace.

Refining the elixir, if the vitality or flame in the body is not well controlled, in the process of solidifying the medicinal liquid, the explosion incident is most likely to occur.

An hour later, Chu Yu exhaled a mouthful of turbid qi with a flushed face, the vitality in his body had been consumed seven or eight out of ten, but when he saw the emerald green and fragrant all-over pill in Xiao Ding, he showed a satisfied smile.

"Great, the first refining was successful, and there is no need to be in such a hurry to get the other medicinal materials." Chu Yu thought excitedly in his heart.

He put away the pill first, then left the cave mansion and went to a stream below the valley, where he took a pleasant bath.

There was no one around, and Chu Yu was a little surprised: "Aren't the people of the Cao family in a hurry to mine this small Yuanjing vein?" ”

"Or maybe their family doesn't look down on this small metacrystalline vein?"

Chu Yu shook his head, this kind of nerve-wracking and non-beneficial thing, he didn't bother to think about it, the most important thing now was that he hurried to complete the most important things in the follow-up.

Refining the whole body pill is just a step in the process, after he cleaned up, he returned to the cave house refreshed, swallowed a pill, and then used his power to absorb the rich vitality in the Bagua Gathering Yuan Array, and restored the vitality lost by refining the pill in his body before.

In this way, after two hours, he had cultivated all the supplies back, and now he had to do the second step of the work, which was to re-purify all the thirty-six fierce beast essence blood.

The essence blood of these fierce beasts sold to him by Feng Jiang of Jubaolou has been purified, but for Chu Yu, their purification techniques are too rough, and they have not completely purified the essence of beast blood at all, which will not have any impact on the absorption and cultivation of ordinary people, but for the complete fusion of his body and soul, it is not at all, he must all be re-refined and purified, and all the impurities of these fierce beast essence blood must be refined.

Thirty-six bottles of fierce beast essence blood took a long time, Chu Yu almost kept refining the essence day and night, and when his vitality was insufficient, he would stop to recover, or just fall asleep.

Anyway, there was water in the valley, and there were some weak beasts and fierce beasts, and besides, he had a lot of dry food and wine in the storage ring on his body, and he didn't worry about starving to death.

Ten days had passed, and he had finally purified all the thirty-six bottles of beast essence blood with his special technique.
