Among the Eight Rank Pills, the "Eight Rank Thunder Tribulation Pill" is the most able to help the Cave Ruins Realm monks break through to the Tribulation Realm.

However, among the eight-rank elixirs, the only one that can help the cultivators of the Cave Ruins Realm assist in cultivating the divine consciousness clone is the "Eight-Rank Divine Separation Pill." ”

The refining difficulty of the two is even more heaven and earth, and the refining difficulty of the eight-rank distraction spirit pill is recorded in ancient books, and even many nine-rank alchemists who have appeared in the past dare not try it easily, because it is too easy to fail.

It is precisely because of the extremely high difficulty of refining that the techniques required for refining are too complicated, and there are hundreds of kinds of spiritual liquid that need to be refined, even in the final stage of the formation of ordinary pills, which requires full attention, and the slightest deviation will lead to everything starting all over again.

Therefore, when refining the eight-grade distraction elixir, the alchemist who refines this pill not only needs to have absolute calmness, but also has absolutely excellent alchemy techniques, at least he must have a full understanding of the hundreds of refining techniques for refining the eight-grade distraction elixir.

Cao Chuan didn't have so many alchemy techniques before deciding to refine the Eight Grades Distraction Pill.

Therefore, after collecting all kinds of alchemy materials and the best Dan furnace, Cao Chuan first began to familiarize himself with all the alchemy techniques needed to refine the Eight Grades of Distraction Pill, and at the same time comprehended the key points that need to be paid attention to no matter what stage of alchemy he needs.

Even the key points that need to be paid attention to in the stage of Chengdan are firmly recorded in his heart, and he does not dare to leave anything out.

Such a move made the phantom of the Demon Venerable Cemetery feel very strange.

There has never been a person in the Demon Venerable Cemetery for alchemy, not for cultivation.

But when he knew that what Cao Chuan wanted to refine was the Eight-Rank Distraction Pill, which was one of the most difficult to refine among the Eight-Rank Pills, he immediately closed his mouth that he wanted to persuade, and instead quietly hid in the shadows and waited for Cao Chuan to refine the pills.

With the help of the alchemy annotations, Cao Chuan was able to quickly integrate all this knowledge into his own sea of knowledge when he comprehended the alchemy technique, and memorized them with the help of an extremely vast sea of knowledge and a powerful soul far beyond ordinary monks.

So after spending three or four days directly writing down the entire alchemy annotations, Cao Chuan began to refine the eight-grade distraction elixir.

The Graveyard Phantom also quietly awakened at this time, hiding itself in the void and secretly observing.

There are a lot of materials needed to refine the eight-rank distraction elixir, as many as three hundred and sixty-five.

Among them, three hundred and forty kinds of materials are some that can be encountered or bought in the outside world, but the remaining twenty-five kinds of materials are rare treasures of heaven and earth, and they can only be seen occasionally in various secret realms or adventures.

This is also a disguised proof of what kind of huge wealth is treasured in the Demon Venerable Cemetery.

Because of these twenty-five materials, Cao Chuan could not only find them in the Demon Venerable Cemetery, but also found many copies, which were enough for him to make a mistake in the process of alchemy.

And that's exactly what happened.

Since it was the first time to refine the eight-rank distraction elixir, Cao Chuan made a mistake in the process of refining the spiritual liquid at the beginning of the first and second refining, and the island master's alchemy failed.

Fortunately, Cao Chuan did not lose too many materials because of this step, and the rest of the materials allowed him to try more times.

And so it goes, with failure after failure and again to keep trying.

Cao Chuan successfully extracted the spiritual liquid and put it into the Dan furnace to start the fusion, and did not make any mistakes.

But when it really came to the final and most critical stage of Chengdan, it was the Cemetery Phantom who first discovered Cao Chuan's limitations.

It turned out that the reason why so many former nine-rank alchemists did not dare to try to refine the eight-rank distraction pill was because in the final step of refining this pill, the divine soul power it needed could be said to be an extremely terrifying existence.

If the divine soul power required by the ordinary eight-rank elixir when it became a pill was only the divine soul power that an ordinary cave ruin realm cultivator could cultivate, then the divine soul power required by the eight-rank divine elixir was several times, dozens of times, or even hundreds of times that of the former.

Although Cao Chuan's sea of knowledge is extremely vast, the power of his divine soul is far greater than that of ordinary Tribulation Realm cultivators.

But for those who want to refine a high-grade eight-grade distraction elixir, it is still just a drop in the bucket.

Just as the graveyard phantom thought.

Even after taking all kinds of pills to restore the power of the divine soul, even Cao Chuan, who had already used the evil qi in his body, still couldn't make himself stable in the most critical step of becoming a pill.

When the pill was about to take shape, Cao Chuan, whose soul power was still exhausted after all, even if he gritted his teeth to keep himself awake, he still had a trance.

Although the refining of the pill has not been affected for the time being, once it continues like this, this eight-grade Dividing Spirit Pill that is about to be successfully refined will definitely fail.

Just when Cao Chuan also began to feel that he was bound to fail.

"Forget it, for the sake of your appetite, we'll help you again!"

"Come on! Let's see if you can refine the Eight-Rank Divine Separation Pill, and let's see how many Divine Consciousness Clones you can cultivate! ”

As soon as the words fell, the phantom of the cemetery hiding in the dark immediately turned into a streamer and escaped into Cao Chuan's sea of knowledge, turning his illusory body into a part of Cao Chuan's sea of knowledge, so that the divine soul power that Cao Chuan consumed when refining the pill was instantly replenished, and it could even be said that it became full, and some of them were difficult to store in the sea of knowledge.

The sudden replenishment of the divine soul power made Cao Chuan feel excited, but he quickly came back to his senses, and immediately lifted his spirit to make himself more focused on the formation of the elixir.

Time is also constantly passing in this situation.

Until ten days and nights passed.

On the fifteenth day of trying to refine the Eight Grades of Dividing the Divine Pill.

Finally, Cao Chuan opened his closed eyes, and his frowning brows finally relaxed.

Obviously, although the refining process this time was still full of twists and turns, it still got a successful result after all.

This made Cao Chuan very excited.

Hurriedly stepped forward to open the Dan furnace that was still steaming, and immediately saw the three eighth-grade Dividing Spirit Pills lying in it lying in it peacefully.

Suddenly.

The Graveyard Phantom said in an extremely weak voice behind Cao Chuan: "I didn't expect you to really be able to refine this eight-grade distraction elixir that even the ninth-grade alchemists didn't dare to try easily, it really impressed us old guys..."

Hearing the voice coming from behind him, Cao Chuan, who immediately understood why there was a divine soul power replenished before, immediately turned to the cemetery phantom, which looked much more scattered and thinner than before, and then said solemnly: "Thank you for the great help of the seniors, Cao Chuan will definitely not forget the help of the seniors." ”

"What the juniors promised before, I will definitely do it with all my heart."

After speaking, Cao Chuan turned around and put the two eight-rank distraction elixirs in the Dan furnace into the storage bag, and the last one was taken by himself.

After taking the elixir, Cao Chuan immediately began to condense the new divine consciousness clone that the cave ruin realm cultivators would do when they broke through the Tribulation Realm.

It's just that his speed seems to be fast.

Before the cemetery phantom came back to his senses, he felt that a second realm of divine soul phantom had appeared in Cao Chuan's sea of consciousness, and the outline was extremely clear, and his strength had reached the sevenfold consummation of the cave ruin realm.
