This was also for the balance of power between the three factions. The refining methods of the various factions were complementary, and none of them had an overwhelming advantage. This way, they could prevent any faction from recklessly attacking others.

As for whether or not there would be people who would attack other sects for the sake of obtaining the other arts, Yi Yan was not worried at all.

None of the three parties were stupid. If someone attacked his faction, the remaining side would naturally help the attacker to resist. Neither side would be an opponent under the joint command of the other two factions.

At the same time, Yi Yan had also erased the names of all the cultivation techniques, in order to prevent them from encountering unnecessary trouble in the future when they reached the Cultivation Realm.

The people of the three sects were currently in a state of turmoil and were not aware of this at the moment. Once they had thought through this point, they would definitely understand the painstaking efforts of Yi Yan.

In the future, even if there were any small conflicts, Yi Yan would still treat them nicely.

Everyone slowly calmed down from their excitement. Just as they were about to thank them again, Yi Yan waved his hand and interrupted them, "It's already very close to a hundred years. I hope everyone can urge the disciples of our sect to train well and strive to become stronger in a short period of time."

The three Sect Leader s all nodded their heads. Just now, they had already scanned through the Jade Chip with their spirit sense, although they had not cultivated it yet, the ingenuity of the cultivation methods recorded within the Jade Chip gave them a feeling as if they were able to break through the clouds and see the blue sky. With just a single scan, many of their doubts from their past cultivation had been answered.

Yi Yan could understand their eagerness to cultivate now, and couldn't help but urge them to speed up their training so that they could leave. Yi Yan then flew out of his flying sword and flew away, after telling the rest of the group that he wanted to train more than ten years.

It was only then that everyone noticed that Imperial Censor Yi Yan's flying swords were only Superior Grade Treasured Artifact. Under their gazes, they sighed at Yi Yan's generosity: He had given them a Spiritual Artifact Ranked Artifact, and he himself even used a Superior Grade Artifact.

Thinking of this, everyone's admiration for Yi Yan deepened.

If Yi Yan knew what they were thinking at this moment, he would definitely not know whether to laugh or cry.

The reason why he only used a high quality treasure was not because he didn't have any good magic treasures, but because he decided to refine another one.

However, this random magic treasure actually caused everyone to have such thoughts. It was as if they had no intention of sticking into the shadows of a willow tree.

After leaving Mount Kunlun, Yi Yan had to carefully think about where he should go to undergo closed door cultivation.

Right now, he couldn't wait to learn the < Nine Revolutions Indestructible Vajra Body > cultivation technique, which was extremely attractive to him.

After thinking about it again and again, Yi Yan finally determined a place — — Mauna Loa Volcano.

On Hawaii, the largest active volcano on earth still erupts.

< p > Body tempering is best performed in harsh environments. The worse the environment, the better.

Compared to the immense pressure on the seabed, an active volcano was undoubtedly a better choice because it could not only provide a harsh environment, but it also contained an enormous amount of energy within the scorching magma. It could solve the problem of the large amount of energy required to cultivate the [Nine Revolutions Indestructible Vajra Body].

After confirming the location, Yi Yan did not stay any longer. His originally slow flying speed had suddenly increased, and like a shooting star streaking across the sky, he disappeared into the eastern horizon in the blink of an eye.

After more than two hours, Yi Yan had already arrived at the Hawaii Islands. It was currently the middle of the night in Hawaii.

Looking down from the sky, the archipelago was in the northwest — southeast direction. The Hawaii Island was located in the southeasternmost point of the island because of an irregular triangle, and Yi Yan's destination this time, the Fanaloa Volcano, was right in the middle of the island.

Yi Yan knew that the volcano had just erupted once, and now was the time when its internal temperature was at its lowest, making it the most suitable time for him to cultivate.

Falling into the bottom of the volcano, Yi Yan adjusted his own condition. The long distance flight just now did not consume too many Genuine Elemental Energy s; all Yi Yan needed to do was to slightly accelerate the circulation of the Taiji Yinyang fish to stabilize itself.

In less than an incense's time, Yi Yan had already adjusted to his peak condition.

The corner of his mouth slightly raised in a perfect curve as Yi Yan rode his flying sword and rushed up the volcano's crater.

The thick smoke that surged into the sky did not obstruct Yi Yan's line of sight. His spirit sense had already thoroughly explored this place, so, as if he was in his own backyard, Yi Yan walked over to the magma that was gradually calming down.

After sensing the temperature of the lava, even Yi Yan, who was a cultivator, did not dare to lightly touch the high temperature of over a thousand degrees. It would definitely cause great harm to his body, but Yi Yan, on the contrary, nodded in satisfaction.

This was because only high temperatures that exceeded the limits of one's body could have the effect of tempering the physical body. If the body could adapt to them, it would become unsuitable.

Yi Yan dived straight down after he finished his investigation. He only stopped after he was less than three meters away from the lava. He had reached his limit.

At this time, blood lines had already appeared on Yi Yan's body, and the blood vessels on the surface of his body were no longer able to endure such high temperatures, so they started to rupture.

Calming his mind, Yi Yan cast a floating array on himself and set up a defensive array around himself.

After making sure that he wasn't disturbed by the outside world, he put the flying sword away and sat down cross-legged.

As his consciousness sank into his dantian, Yi Yan officially started his closed door cultivation.

First of all, Yi Yan had studied the《 Nine Revolutions Indestructible Vajra Body s》 from beginning to end. As his understanding deepened, Yi Yan once again received a deep shock.

Yi Yan had also heard of the Body Refinement Method before. Ordinary body tempering techniques would only temper the muscles and bones, and would rarely be used on the cultivation of the internal organs. This was because the internal organs were the most vulnerable parts of the body, and it was even harder to store energy and increase in strength.

When he practiced the < Nine Revolutions Indestructible Vajra Body >, the strength of his internal organs would increase at the same time. Although the improvement was not comparable to the improvement of his muscles, bones and muscles, it was already much stronger than the other body tempering arts.

< p > Because ordinary body tempering techniques constantly destroy cells and then reorganize them, they constantly temper during the process of recombination to increase their strength.

"Nine Revolutions Indestructible Vajra Body", on the other hand, was different. When training, one did not need to destroy cells, but instead, through continuous energy fusion, it would increase the activity of muscle cells, stimulate the cell's division, increase the limit of the body's and organs's capacity for energy, and thus increase the upper limit of the body's capacity for energy.

Therefore, normal body tempering techniques were usually represented by the body's strength equivalent to a certain level of magical equipment at different stages, while the "Nine Revolutions Indestructible Vajra Body" was directly represented by the body's energy.

Moreover, after training [Nine Revolutions Indestructible Vajra Body], the different parts of the body's energy could be transferred to each other. It was unlike an ordinary Body Refiner, where the strength of the body's parts was constant.

Although it was hard, it could easily be broken if struck by energy that was outside of its tolerance range. On the other hand, the body that the Nine Revolutions Indestructible Vajra Body cultivated was more like a piece of leather that had been soaked in water, it was not only strong but also flexible. Whenever a part of the body was attacked, it would naturally disperse its power to other areas, thereby avoiding damage and greatly increasing the upper limit of the body.

In terms of the results of their cultivation, a tribulation stage cultivator who cultivated an ordinary body refinement technique would have the highest strength equivalent to a high-grade spirit artifact. It was equivalent to adding the protection of a high-grade spirit armor to his body, and his physical attack was equivalent to a high-grade spirit artifact.

The energy in the body of the practitioner of "Nine Revolutions Indestructible Vajra Body" at the same level was also at the tribulation level, but the strength of the defense and attack had reached the level of a Top-grade Spiritual Artifact. Furthermore, when attacking, one could channel all the energy in the body.

The difference between the two was clear at a glance.

Slowly circulating the [Nine Revolutions Indestructible Vajra Body] cultivation technique, Yi Yan could clearly feel a warm feeling from inside to outside, as if every cell was jumping in joy. For a moment, Yi Yan was deeply engrossed in it.

Time flowed steadily forward like a passing river.

Yi Yan, who was completely immersed in cultivation, seemed to have forgotten everything that was happening outside. He was completely unaware of the rotation of the sun and moon, as he focused all his attention on improving the energy in his body, and sat steadily like a statue.

Yi Yan dived straight down after he finished his investigation. He only stopped after he was less than three meters away from the lava. He had reached his limit.

The current Yi Yan was less than three inches away from the lava.

All of a sudden, the magma that was rolling up and down like it usually did, instantly became berserk, sweeping up layers after layers of red waves as it rushed towards the meditating Yi Yan.

If someone were to spectate from the side, they would be surprised to discover that the fiery red lava, that was an inch or so away from Yi Yan's body, had already turned dark, like a poisonous snake whose life had been sucked out, and hung down powerlessly.

In the midst of the continuously rising lava that was powerlessly hanging down, Yi Yan was like a reef that had stood tall and upright on the beach since ancient times.

However, even if Yi Yan was wearing the clothes of a treasure that he had taken out from the storage ring of Hong Xuan, under the impact of these layers of heat waves, he was in a tattered state, as if he would be burnt to ashes by the next wave.

Finally, along with a surging wave of waves, the daoist robe on Yi Yan's body completely turned into ashes and disappeared into the wind.

Only, the current Yi Yan had already entered into a state of deep meditation, and the outside world was unable to disturb him. Even if he had already become a naked fruit, Yi Yan still did not feel anything.
