Cao Fan tried to extend his divine sense to the extreme, but he didn't see the exit of the crack space at all.

Obviously, the body of the Taishang Nine Realms was not static after entering the rift space. In the past few days, I don't know where I have drifted.

Cao Fan knew he had to go out. In this rift space, if he only allowed the body of the Supreme Nine Realms to wander around, I am afraid that he would not be able to hope to find an exit in his life.

As soon as his body left the Taishang Ninefold Realm, Cao Fan felt the terrifying oppressive force violently attacking him from all directions.

If it weren't for the fact that his stamina had already broken through the four hundred mark, he would either be forced to flee into the Taishang Nine Realms again under such a powerful oppressive force, or he would be crushed into a puff of blood mist.

Even so, Cao Fan felt quite uncomfortable, as if the bones in his body were about to fall apart.

I didn't expect that the environment in this crack space was so bad, which Cao Fan couldn't feel at all through his divine sense before.

Cao Fan did not choose to escape back to his true spirit world, but instead activated the Chaos God Body Technique and began to refine his body.

That's right, it is a desperate crack space for others, but it is the most ideal place for Cao Fan to refine his body.

As Cao Fan used the body refining exercises, the astonishing oppression on his body immediately weakened, and it had reached a level that he could barely bear.

A few days later, the pressure of the crack space could no longer meet Cao Fan's refining needs.

After entering the rift space, Cao Fan began to try to escape into the distance for the first time.

Sure enough, as soon as his body shifted, Cao Fan immediately felt that the pressure he was under was raised to a higher level again.

If this had been an ordinary Mahayana monk, I am afraid that he would have died a long time ago. Even if it is a strong earth immortal, there are not many people who can be safe and sound in this stressful environment.

Cao Fan also felt very uncomfortable, but he also had the Chaos God Body Technique, and when this powerful body refining technique was operating, it enhanced his physical toughness, so that he could barely continue to support it without having to hide in the Taishang Nine Realms.

Previously, Cao Fan had already touched the barrier of refining his body cultivation to break through the realm when he was in the time whirlpool, and at this time, under the continuous impact of the high-pressure environment, the barrier of his body refining was finally completely loosened.

There are three stages of refining, namely the Tempering Realm, the Rock Realm, and the Vajra Realm. Among them, each stage has three major realms, which become the first, second, and third heavens.

Reaching the realm of the peak of the Triple Heaven of the Tempering Realm, even those who have not cultivated the true realm, the strength of the physical body can reach the level of the half-step body shaping realm.

In the future, the first heaven of the Rock Realm is equivalent to the physical strength of the monks of the Shaping Period, the second heaven corresponds to the monks of the Tribulation Period, and the third heaven is the physical level of the strong people of the Mahayana Period and the Earth Immortal Stage.

Cao Fan had already been a refining body cultivator in the Triple Heaven of the Refining Realm before, and after encountering huge refining opportunities in a row, the last refining barrier in his body was also broken through.

Feeling that the strength of his physical body had skyrocketed, Cao Fan knew that he had broken through to the Rock Realm One Heavy Heaven, and at the same time, he had also increased thirty points of stamina attributes, and even the remaining injuries on his original left shoulder had completely recovered as before.

As a result, the pressure atmosphere that originally made him very uncomfortable suddenly had a sharp effect, and he could no longer even help improve Cao Fan's body refining cultivation.

How can this work?

Cao Fan, who had tasted the sweetness, was willing to let go of this once-in-a-lifetime opportunity to refine his body, and immediately flew away to the depths of the crack space again.

This retreat took two days, and Cao Fan finally found a suitable place for the new body refining.

This time, Cao Fan spent more than a month refining his body, and only then did he reluctantly raise his body cultivation to the peak of the first heaven in the Rock Realm.

After that, no matter how hard he tried, the entry of the refining body was always very slow.

Cao Fan did not continue to consume time, but stopped to analyze what the problem was.

As far as he knew, refining bodies also had refining potential. This value does not meet the standard of breaking the realm, and no matter how hard you try, the effect is minimal.

To increase the potential value of body refining, in addition to looking for relevant top-level heaven and earth treasures, that is the elixir of body refining.

Cao Fan did have a lot of body refining pills, but they were all Yuanying-level spirit pills, which were almost completely useless for his current body refining.

However, among the pills that Cao Fan mastered, there were no middle-level body refining pills or high-level body refining pills at all.

There is no Dan Fang who can deduce it by himself, and Cao Fan's deduction alchemy is best at this.

The next moment, Cao Fan finally returned to the Taishang Nine Realms.

He began to deduce the Dan Fang of the Intermediate Body Refining Pill.

In the past, Cao Fan deduced alchemy, and often studied the pill in a few hours at most. Even if it was the refining pill recipe of the Blood Shadow Pill that Yuan Zhaoxing had long since lost, it hadn't taken him more than a day to deduce it at the beginning.

However, this time to deduce the mid-level body refining pill, Cao Fan spent a full six days.

This is not to say that Cao Fan's level of deducing alchemy has declined, but that he lacks the top-level treasure of the cultivation realm, the "Divine Network Secret Bud".

This is an earth immortal-level heavenly material and earth treasure, if it is used to deduce the Dan Fang, Cao Fan will already be able to refine the mid-level body refining pill.

The problem is that he doesn't have this kind of treasure in hand, and using it to deduce Danfang is a joke at all.

Cao Fan could only use other similar materials that he had at hand that were much less effective as substitutes, which naturally greatly increased the difficulty for him to deduce the new Danfang.

After more than half a month, Cao Fan finally found a replacement for the middle-level Body Refining Pill.

He replaced the Shenluo Secret Bud with Kailuo Fruit and Silver Moon Sand, as long as the ratio of the two is accurate, the effect is directly after the Shenluo Secret Bud, plus the medicinal effect produced by the combination of Xuanfetal tendon and True Liulu, the middle-level body refining pill will have a play.

These are all Mahayana level top-level materials, which are slightly easier to get than the Shenluo Secret Buds, at least Cao Fan has the amount of refining a few furnaces.

Next, Cao Fan carefully deduced the alchemy pill for dozens of furnaces to ensure that nothing went wrong before he began to refine the entity mid-level body refining pill.

After more than half an hour, the medicinal fragrance in the Dan furnace was already overflowing.

As Cao Fan's last pill collection trick was played, twelve shiny purple pills had already flown out of the Dan furnace in turn and fell into the two pill bottles that he had prepared.

Intermediate Body Refining Pill, Cheng!

After being delayed for so many days, Cao Fan couldn't wait to rush out of the Taishang Nine Realms again, and after swallowing a mid-level body refining pill, he once again hit the body refining cultivation.

This time, the shackles of cultivation that Cao Fan had been unable to overcome before were easily broken. Cao Fan's body cultivation rose rapidly, and he finally broke through to the middle stage of the first heavy heaven of the Rock Realm.

Cao Fan's figure continued to fly towards the depths of the Split Sky Space, looking for a new place to refine his body.

Three or four hours later, Cao Fan's figure suddenly stopped.

He didn't find the right refining environment he needed, but he was shocked by the large number of huge insects flying in front of him.
