Gu Yan, who had gone through a test of life and death, was meditating and cultivating at this time, because Ghost Ku told him that there was still a large amount of fire source spirit pulp energy in his body that had not been completely refined.

After all, the fire source spirit pulp is a genius earth treasure comparable to the king-level elixir, although it is only a drop, but the energy contained in it cannot be underestimated. For Gu Yan, a martial artist in the Martial Yuan Realm, it would take a while to concentrate on refining before he could completely absorb it.

This may take a lot of energy for ordinary people, but for Gu Yan who cultivates the Great Five Elements Technique, as long as it is the energy of the Five Elements attribute, it is a super tonic. In particular, this kind of rare genius earth treasure has multiplied the benefits of Gu Yan's cultivation of the Great Five Elements Technique.

Moreover, after the tempering of the fire source spirit pulp, Gu Yan's physique was unconsciously strengthened by a few points. Moreover, Gu Yan found that the various mechanisms of his body, including speed and strength, had been greatly increased.

"It is worthy of the spiritual pulp brewed by the Fire Spirit Holy Fruit, and the effect is against the sky, and now if he is against that poisonous Lao Tzu, one less punch can seriously injure him. Gu Yan secretly estimated in his heart.

After cultivating for about an hour, Gu Yan happily jumped up from the stone platform where he was meditating, and the ghost on the side asked with some curiosity, "Boy, what happened, so happy." Didn't it make you concentrate on absorbing the energy of the fire source spirit pulp, what are you smirking at here?"

"Ghost Elder, the remaining energy of the fire source spirit pulp has been absorbed by me, and the reason why I am so happy is because I found that the cultivation of the Great Five Elements Technique has advanced, and now it is no longer an entry realm. Gu Yan's tone was filled with excitement.

Hearing that Gu Yan had actually absorbed the residual energy of the fire source spirit pulp, Ghost Ku was also slightly shocked. How strong the energy contained in the fire source spirit pulp is, the ghost wither is very clear, even a martial artist in the middle stage of condensation may not be able to refine it in an hour.

"It seems that the 'Great Five Elements Technique' you have cultivated is really an anti-heaven exercise, which really makes the old man a little envious!" said with a smile.

However, although the ghost wither was envious, he was powerless, even if he knew that Gu Yan would not be stingy with the exercises of the Great Five Elements Technique. It's just that if you want to cultivate the Great Five Elements Technique, you have to scatter your skills and recultivate, not to mention that the physique of the Ghost Dry Demon Clan is not suitable for cultivating it.

"Boy, your exercises have actually advanced, and you haven't wasted a drop of the essence of the Fire Spirit Holy Fruit! Oni Ku said with a serious face.

Although Gu Yan was a martial artist in the Wuyuan Realm at this time, and his cultivation was not low, he had to know that refining the fire was an extremely dangerous thing. In history, there are countless masters who have died or been seriously injured because of refining fire, and even the masters of the Divine Soul Stage dare not take it lightly.

Moreover, Gu Yan has also heard of the danger of refining fire, but these cannot stop Gu Yan's determination to refine fire. His goal is to refine a different fire that ranks in the top ten on the list of different fires in the future, and now if even an ordinary beast fire is afraid and afraid to try, then how can he talk about refining a more advanced different fire.

Gu Yan nodded slightly, but at this time, the ghost withered was refining the pill on the side, and the Dan furnace was obtained from the King-level Alchemy Pill Ding in the secret realm of the Spirit Venerable.

At this time, the elixir refined by the ghost wither was also prepared early, and it was a kind of elixir specially refined for Gu Yan to refine the Red Demon Flame Flame - Ice Spirit Pill! The Ice Spirit Pill was a well-known pill in the cultivation world, and it was a kind of pill specially developed for martial artists or Dan masters to refine the fire.

According to the level of the elixir refined, the Ice Pill is divided into three grades, and the first grade of the Ice Pill belongs to the high-level elixir of the spirit level, and it is also the Ice Pill that the Ghost Ku is refining at this time. A grade of Ice Spirit Pill only needs some elixirs that have reached a hundred years in age, and the difficulty of refining them is not very great.

The second-grade Ice Spirit Pill is a high-grade elixir, ranking at the middle level of the king rank, and the difficulty of refining it is already quite high. It is suitable for martial artists ranked in the seventy realms and thirties on the refining and alien fire list, and the elixirs required for refining are all thousand-year-old elixirs of extraordinary value.

However, for Gu Yan's refining of the Red Demon Flame, it seems to be a bit overkill, and moreover, the alchemy of the ghost withering cannot refine the second-grade Ice Spirit Pill.

As for the Three-Rank Ice Spirit Pill, not to mention the value, it is an emperor-level primary pill that can only be refined by a refining master. For refining Dragon Flame, Immortal Fire, or the top 30 Alien Flames on the Alien Fire List, it is a necessary elixir. The elixirs refined are all rare elixirs that are more than 5,000 years old.

Every time a three-grade Ice Spirit Pill appeared on the mainland, it would cause an uproar. Many big forces have robbed each other as the foundation of the sect. After all, this kind of thing can be encountered but not sought, if you are lucky enough to encounter a high-level fire, it will be of great effect.

After Gu Yan meditated and prepared for about half an hour, he had already adjusted his body to the best state. At this time, the Devil's Dry Ice Spirit Pill had already been successfully refined.

"Boy, let me remind you first, even if the refining fire is assisted by the Ice Spirit Pill, the danger is definitely not to be underestimated. When refining, you must be wholehearted, I will give you the Dharma protection throughout the whole process, otherwise nothing will disturb you. As he spoke, he threw the Ice Spirit Pill to Gu Yan.

Gu Yan was stunned, and then took out the small jade bottle where the Red Demon Flame was placed, and unsealed the seal on the jade bottle, and suddenly a blazing power overflowed around Gu Yan.

"Gu Yan, the Ice Spirit Pill is refined with various elixirs with extreme ice attributes, wait for you to take that Ice Spirit Pill in your mouth, and then swallow the fire seed down. At this time, you must pay attention to wrapping the fire refining with true yuan, otherwise even if you have the protection of the Ice Spirit Pill, your meridians will be pierced by the scorching power of the fire. ”

Gu Yan nodded, and then swallowed the white smoky Ice Spirit Pill in one gulp, at that moment, Gu Yan's whole person seemed to be frozen in an instant, a layer of white frost condensed on his hair, and a bone-piercing cold air floated out from Gu Yan's body.

"Gu Yan, quickly swallow the Red Demon Flame into it, and pay attention to mobilizing the vitality to protect the fire. There was a hint of anxiety in the ghost's tone. After all, this Ice Spirit Pill contains an extreme cold qi, although Gu Yan's physique is strong, this cold qi is also a lot of damage to the body.

Gu Yan was stunned, and swallowed the fire into his mouth with great difficulty, and in an instant, Gu Yan's body was no longer cold, but red. That kind of tempering of the two heavens of ice and fire is not an ordinary pain for a martial artist.

Gu Yan's face was pale, his muscles were bulging, and he looked extremely painful, but at this time, he couldn't be distracted to do other things at all. With one mind, he mobilized the true yuan to wrap the red demon flame, and slowly entered the dantian.

When the Red Demon Flame was slowly moved into the dantian, the ice crystals formed by the Ice Spirit Pill in various places of the ancient rock meridians were instantly evaporated by the scorching qi that escaped from the Red Demon Flame. Those condensed ice crystals, the moment they were evaporated again, and the power of extreme heat, constantly quenched the internal organs of the ancient rock.

Although the process of refining was very painful, Gu Yan smiled, because before, Ghost Ku had said that although cultivating "Demon God Transformation" could greatly increase Gu Yan's physique, it was only the enhancement of his outer body.

However, the enhancement of the five internal organs and the eight veins of the Qi Jing is very small, and the enhancement of the inner body has been a huge hurdle that has been difficult for martial artists to cross since ancient times. Nowadays, there is such an opportunity to strengthen the meridians, and Gu Yan will naturally not let it go.

Gu Yan gradually slowed down the speed of the fire, making the test of the two heavens of ice and fire more intense, however, the pain brought to Gu Yan was naturally more intense.

Seeing the ghost withering here, his heart tightened, he didn't know why Gu Yan would choose such a risky approach, but he didn't stop it, but guarded Gu Yan tightly.

This kind of ice and fire torment lasted for half an hour, and at this time, Gu Yan didn't have much reaction to this pain, and his face was straight.

Suddenly, Gu Yan, whose eyes were tightly closed, shouted, "It's time, Red Demon Flame, refine it for me, the first weight of the Great Five Elements Technique, the Burning Sun Reversal!" In an instant, a tornado suddenly appeared around Gu Yan's body, frantically devouring the surrounding heaven and earth vitality.

"This kind of speed of absorbing vitality is worthy of a peerless exercise, what a demon!" Ghost Ku said with a smile, at this time, the success of the ancient rock refining fire was already under control.

The vitality in the entire Void Tower seemed to be attracted by Gu Yan's body, and they all surged towards the place where Gu Yan was. Gu Yan's entire body seemed to be wrapped in a Yuan Balloon, frantically urging the exercises to refine the Red Demon Flame.

However, the refining process was extremely fast, and before even a quarter of an hour had arrived, Gu Yan got up and patted the dust on his clothes.

"Ghost elder, I've succeeded in refining. Gu Yan said happily to the ghost wither, and at the same time, with a finger of his right hand, a red flame appeared in his hand.

At the same time, Gu Yan flicked his index finger, and a fire bomb smashed towards a boulder in front of him, and in an instant, the boulder burst open.

"Yes, yes, this blow is already comparable to the full force of a master in the late stage of the Martial Yuan Realm. However, Gu Yan, why did you suddenly slow down the refining fire halfway, don't you know that such a practice is dangerous?"

However, Gu Yan touched his head and said with a smile, "Ghost Lao, I know it's dangerous to do that, but it's worth it." Because the tempering of the two heavens of ice and fire has an excellent effect on the enhancement of my internal organs. Today's meridians are several times stronger than before. ”

Saying that, Gu Yan Void punched, and the Zheng fist wind and fist strength seemed to have produced a wind blade, which was extremely powerful, enough to see how terrifying Gu Yan's punch was!
