The aura of heaven and earth absorbed by one's own cultivation is too idle and mixed after all, and it must be continuously tempered before it can be turned into pure liquid yuan power and stored in the liquid water droplets at the dantian.

And the Demon Dragon Emperor is a peerless powerhouse, and the aura absorbed from its body is naturally thick and clear, and it can be directly turned into its own use. Of course, fortunately, Du Feiyun's meridians are very tough after being tempered thousands of times, otherwise they really can't withstand its majestic mana.

Just after absorbing dozens of breaths, Du Feiyun clearly noticed that the liquid water bead at the dantian had increased by one point, and the yuan power in his body was even more majestic, and this discovery made him secretly happy.

"Bastard, let this emperor go out of the way!, otherwise this emperor wants you to die without a place to bury!" Being extracted by Du Feiyun wisps of his hard-earned spiritual energy, the Demon Dragon Emperor suddenly became furious, and while violently resisting and struggling, he let out a spiritual roar.

"Hmph! I really don't know whether to live or die! If you fall into my hands, you only have the life of being refined, and you still want to threaten me?" Du Feiyun snorted coldly, his eyebrows were full of coldness, and the Spirit Devouring Technique suddenly strengthened its power, and the speed of extracting spiritual energy became faster and faster.

Looking at the spiritual flow of the thickness of the little thumb extracted from himself, which suddenly became the thickness of the index finger, the Demon Dragon Emperor suddenly became even more furious, and the struggle and rolling became more and more intense. It's a pity that this time, no matter whether he roared, scolded angrily or threatened, Du Feiyun was unmoved, and kept concentrating on absorbing its mana.

Time passed quietly, and the empty hall was dark and silent, and there was no sound. Deep inside Feiyun Peak, this secret room was extremely quiet and closed, and without Du Feiyun's order, no one would disturb his cultivation at all.

At this time, a month had passed, and Du Feiyun had finally stopped absorbing the mana of the Demon Dragon Emperor and stopped using the Spirit Devouring Technique... That's when I opened my eyes. He immersed himself in his body with his spiritual sense, checked the flow of Yuan Force in his body, and sensed the majestic Yuan Force surging in the meridians, and a smile of relief suddenly appeared on his face.

"Finally reached the peak of the innate ninth layer! As long as I fuse the power of the five elements to perfection, I will be able to touch the shackles of the Jie Dan Realm, comprehend the date of the Heavenly Tribulation, and impact the Jie Dan Realm!"

Idle cultivators can only advance from the innate ninth layer to the peak of the innate ninth layer by cultivating for a few years, but Du Feiyun only took a short month, I have to say... Among them, the Demon Dragon Emperor has the most credit, but the current Demon Dragon Emperor is dying, and even the aura of Jin Sè's body has become much dimmer. It struggled frantically and cursed and roared for half a month, but Du Feiyun remained unmoved, absorbing its mana without distraction, and it had to recognize the reality and give up the threat and roar.

Now it's... has been suppressed and refined for so long, and has been extracted fifty percent of the mana by Du Feiyun, although he still has the strength of the Silver Dan Realm... but he was very weak.

Du Feiyun didn't bother to pay attention to it, anyway, in his eyes, this Demon Dragon Emperor was no different from spirit stones and pills, just items that provided him with mana to improve his strength.

With a wave of his hand, he put away the Eight Swords of Zhenlong, and Du Feiyun no longer practiced in retreat, but sacrificed the Nine Dragons Ding and began to refine the pill. This time, he was going to refine the Five Elements Spirit Pill, and after taking it himself, he would condense and fuse the power of the Five Elements.

I had the experience of refining the Five Elements Spirit Pill for Xue Bing last time, and refining this elixir again was naturally very familiar... The material of Strange Dust Thorium was not used up last time, and the rest of the materials were also prepared in his treasure house.

The method of ascending Dan, the method of descending Dan, the technique of seven volumes of wild waves, the technique of eight folds of the storm tide, and the potential of flowing clouds and rivers and the potential of a hundred flowers and dragons... The eighteen methods of alchemy and the nine spells of the Dan Dao Divine Power, as long as he knew it, he would do it with all his might.

All of this he did was nothing more than to improve the quality of the Five Elements Elixir!

Eight hours passed quickly, and Du Feiyun, who was fully immersed in the Nine Dragons Ding, finally relaxed, waved his hand to open the lid of the Nine Dragons Ding, and immediately there was a strong medicinal fragrance to spread his mind, and with a move of his right hand, there was a multicolored aura condensed match, rolling up the five pills flying out of the Dingkou and bringing them to his palm. Holding the five crystalline elixirs with different faces, he carefully examined them with his spiritual sense, watching them smell their fragrance, and probing their moire patterns and internal uniformity.

After a while, he was finally sure that these five pills were all of the excellent quality of the six grades! Although this time when refining the Five Elements Spirit Pill, there was no vision of the elixir when the furnace was opened, which made him a little disappointed, but this was indeed the highest quality pill he had refined so far, and he was finally relieved. ...,

After meditating and cultivating for a few days, and restoring himself to his peak state, Du Feiyun took the Five Elements Elixir and began to digest and absorb the medicinal power in it, condensing the power of the Five Elements.

The Yuan Force Seed in his body was already a liquid water drop the size of an egg, crystal clear and very clear, containing the majestic Yuan Power. It's just that the sè division of this Yuan Force seed is a little uneven, and it is obvious that the fiery red sè occupies most of the half, and the ice blue sè is the weakest.

This is the phenomenon that the power of the five elements is not yet uneven, and only when the power of the five elements is fused and penetrated to form an absolute balance and circulation, the seed of Yuan Li will be a crystal clear multicolored sè.

After taking the Five Elements Spirit Pill, the medicinal power of the elixir immediately began to emanate, rushing towards his meridians and limbs, constantly rushing and rushing. Three hours later, the medicinal power of the elixir completely exploded, Du Feiyun suddenly frowned, fine beads of sweat oozed from his forehead, and the meridians on his arms and face were also highlighted, beating suddenly.

Obviously, the quality of this Five Elements Spirit Pill was too high, and the medicinal power was too majestic, and after it exploded in Du Feiyun's body, it immediately brought him great pain. But he has always endured, supported by extremely tenacious willpower, maintaining the clarity and stability of his mind, attracting the surging medicinal power like a flood, and wandering and washing in the meridians.

The very tough meridians that had been tempered and opened up were torn apart and expanded little by little, and then repaired and tempered little by little. Just like the intense pain when he took the Rebirth Pill, Shi Zhongling and Qingyun Traceability Pill, Du Feiyun's entire body was tense, his teeth were clenched, and countless fine beads of sweat oozed from his body.

This is not only a painful torment, but it is also a tempering of the mind, which is of great benefit to him to improve his mental cultivation and spiritual strength, so he has been gritting his teeth and insisting on not fainting.

Finally, a month later, the torment was finally relieved, and the power of the raging medicine finally softened. At this time, his meridians were doubled again, the Yuan Force Seed was also doubled, and the strength of the Yuan Force stored in his body was also doubled.

Of course, after a long period of accumulation and this training, his spiritual cultivation finally made a huge breakthrough, reaching the consummation realm of the innate stage, and approaching the Great Cultivator of the Jie Dan Realm. He was confident that even if the spiritual sense attack of the Great Cultivator of the Silver Pill Realm was attacked, he was afraid that it would not be able to hurt him.

The harvest was huge, and he was very happy in his heart, but he was not arrogant or impatient, and continued to cultivate quietly, absorbing and refining the medicinal power of the Five Elements Spirit Pill.

Half a year later, when the medicinal power of the entire Five Elements Spirit Pill was completely digested and absorbed, penetrating deep into the bone marrow into his limbs and meridians, he finally succeeded in integrating the power of the Five Elements.

Since the retreat, in more than a year, the speed at which his strength has improved is terrifying, and it takes others at least five or six years to do it, but he has completed it in just over a year, which is simply a demonic speed.

At this moment, the Yuan Force Seed in his body was the size of a fist, twice the size of a cultivator of the same realm. In the same way, the strength of his Yuan Force, the power of Yuan Force when it exploded, and the degree of condensation of Yuan Force were all twice as strong as those of cultivators of the same realm!

It is no exaggeration to say that even if he does not use magic weapons, he can easily kill ordinary monks of the same realm with only magic attacks, which is the advantage of a solid foundation that is far twice that of ordinary people!

Moreover, his Yuan Force Seed is evenly divided, and the multicolored aura is evenly divided, flowing very mellowly, which is the phenomenon of the fusion of the power of the five elements.

When he finally finished his cultivation and woke up from his meditation, when he opened his eyes, a flash of joy suddenly flashed in his eyes.

"The period of the Heavenly Tribulation is fourteen months later!"

Du Feiyun finally touched the shackles of the Jie Dan Realm, cultivated the Innate Realm to a consummation level, and realized the date when the Five Elements Thunder Tribulation descended. After going through hardships and dangers all the way, experiencing life and death crises for a long time, repeatedly stepping on the edge of life and death, and practicing hard for several years, what I am waiting for is this moment, and what I look forward to is the day when I break through the gap between heaven and man!

At this moment, he wanted to tell his mother and sister that he had finally grown up, and he also had the opportunity to become a great monk respected by all people, embarking on the path of immortal cultivation, and would never let his mother and sister suffer again in the future.

He wanted to say to the old man who was always old and unscrupulous, that he had finally touched the threshold of the Yudan realm, and he would soon be promoted to the rank of Great Cultivator, to avenge him and recover his blood debt!

He wanted to say to that beautiful woman in a white shirt that he finally had the opportunity to become a great monk and fulfill his promise to Xue Rang to protect and take care of her!

Thinking of this, Du Feiyun woke up again, and suddenly remembered in his heart that more than a year ago, Xue Bing realized the period of the Heavenly Tribulation, and then entered the Liuyun Heavenly Palace to retreat and cultivate, which has not yet appeared.

He clearly remembered that the date when the Heavenly Tribulation that Xue Bing felt at that time was three years later on the Double Ninth Festival. A touch of strangeness suddenly flashed between Du Feiyun's eyebrows, and after a little thought, he found that Xue Bing's Heavenly Tribulation was descending on the Double Ninth Festival next year, and there were still fourteen months before now.

And his own tribulation will also come in fourteen months!

Could it be that his Heavenly Tribulation will fall at the same time as Xue Bing's Heavenly Tribulation? Is this a coincidence?

Thinking of this, a strange look suddenly appeared on Du Feiyun's face, which was very complicated and difficult to understand. He didn't expect that he would cross the tribulation with Xue Bing at the same time and attack the Yudan Realm together!。
