The role of the Blood Essence Pill is very simple, and its main role is to purify and refine the bloodline, which has a fatal allure for the creatures inherited by the bloodline. This elixir is not something that can be refined by human beings, but by a blood spirit demon vine, which is a natural creation.

Blood Spirit Demon Vines are extremely rare, and there are not necessarily a few Imperial Clans with bloodline inheritance, and Chu Duan only got one in the Forbidden God Realm. And generally speaking, the medicinal effect of the Blood Essence Pill is limited, and it has the best effect on Nirvana monks, and the effect on Shenyuan monks is very small, and it is even more insignificant for the Cave Heavenly King.

But Chu Duan's Blood Spirit Demon Vine was different, first of all, that Blood Spirit Demon Vine was rooted in the Abyss Tribulation Soil, and the grade of the Abyss Tribulation Earth was likely to be supreme level. Taking root in this soil, the Blood Spirit Demon Vine quickly broke through the limitations and evolved to a higher level.

As the era of the end of the law gradually faded, the golden era gradually arrived, and the suppressed abyss catastrophe was recovering, and the evolution of the blood spirit demon vine was not stopped, but was getting faster and faster.

In the boundless black ocean of the Sword Casting Abyss, Chu Duan absorbed the power of Heaven and Earth Origin Creation, and once injected part of the Heaven and Earth Origin Creation Power into Qifu Cave Heaven. All the creatures in the entire Qifu Cave Heaven ushered in a great opportunity, breaking through the limitations of their own race level and completing a transformation.

There is also the will of Chu Duan to refine the "Heaven" and prove the innate soul when it is inevitable, it is inevitable that some of the innate power will leak and be absorbed by the creatures in the Qifu Cave Heaven.

Any of these chances is not trivial, not to mention that it is superimposed many times, the blood spirit demon vine has already evolved to a terrifying level, not to mention that for the king of the cave heaven, the blood spirit pill produced will also have a great effect on the gods.

The pills or heavenly treasures that can purify and refine the bloodline are originally extremely valuable, not to mention the blood essence pills that have an effect on the gods, I am afraid that the value of any blood essence pill at this time is not inferior to the Heaven Winning Pill, and Chu Duan is three as soon as he makes a move.

The medicinal power of the three Blood Essence Pills was all submerged into Granny Huang's body, and the phoenix bird behind Granny Huang spread its wings, and waves of fire swept in all directions, and the terrifying power was agitated, and even Nangong Yu and Huoqi Phoenix felt a strong threat.

Nangong Yu's heart moved, and the power of the Dao Rank Formation spread out, and the heavy waves of fire were bound within a certain range by the invisible force, and did not spread farther away, otherwise the entire Fire Phoenix Palace would turn into ashes.

Granny Huang was shrouded in flames, and fiery red feathers appeared on her smooth skin, and in a blind eye, she had turned into the body of the phoenix bird, and became one with the phoenix bird that appeared behind her.

The phoenix bird let out a long roar in the sky, and the fiery red feathers withered and annihilated in the flames, and at the same time, crimson feathers continued to grow, replacing the fiery red feathers that withered and annihilated.

The Fire Habitat Phoenix was ecstatic and said: "The bloodline is traceable, it is the bloodline. ”

Nangong Yu nodded and said, "That's right, the medicinal power of those three Blood Essence Pills is too powerful, not only allowing my aunt to get rid of the shackles of the bloodline, but also directly tracing the origin of the bloodline and evolving towards the Fire Phoenix." ”

Granny Huang is a phoenix bird, and the phoenix bird clan is a bloodline descendant of the Fire Phoenix Emperor clan, but it has already become a family of its own. If it is an ordinary elixir or a treasure of heaven and earth that purifies and refines the bloodline, it will only refine Granny Huang's phoenix bird bloodline, making her phoenix bird bloodline more refined.

However, the medicinal power of those three Blood Essence Pills was too strong, and Granny Huang's own Phoenix Bird bloodline was already very pure, so she directly pushed her bloodline to a new level, and evolved towards the source Fire Phoenix bloodline under returning to its origins.

A higher bloodline means stronger strength, and after evolving into a fire phoenix, Granny Huang is the imperial bloodline, which is at least two percent stronger than the same level.

After two hours, all the fiery red feathers of the phoenix bird were replaced by red feathers, the fiery red claws also turned red, the feathers on the tail became more slender and gorgeous, and the phoenix bird officially evolved into a fiery phoenix.

The fire phoenix let out a high-pitched long roar, and with this long roar, the space in front of her was suddenly torn apart, manifesting a spatial passage to endless time and space, and the fire phoenix was wrapped in surging flames and submerged into the spatial passage.

"The last step, as long as you successfully open up the cave space in the endless time and space, the realm breakthrough will be considered a success. "Firedwine Phoenix was a little nervous and a little excited.

Yu Yao grabbed Chu Dui's arm, Chu Duan also clearly felt her nervousness, and comforted: "Don't worry, this is the Nangong family, and the endless time and space are also guarded by the Supreme Formation, and the chance of a successful breakthrough is very high." ”

The last step for the Shenyuan Peak Giant to break through to the Cave Heaven Realm is to open up a Cave Heaven Space in endless time and space, which can also be said to be the most critical step. The endless time and space are dangerous and abnormal, and even the outermost part is full of unknown dangers, which can easily obliterate the peak giants of Shenyuan.

However, for the monks of the super power (giant clan) and the top power (imperial clan), the success rate of breakthrough is often higher than that of other forces. Because the power of the Supreme Formation and the Emperor-level Formation can penetrate deep into the Endless Time and Space, providing them with a layer of protection and preventing threats from the outside.

The waiting time is often unusually long, and the spirit is always in a state of tension and anxiety, especially Huoqi Huang and Yu Yao, who have too deep a relationship with Granny Huang.

In this way, three hours passed, a space in the Fire Phoenix Palace suddenly rippled, and then a spatial passage appeared, and a beautiful woman in her thirties stepped out of the spatial passage.

"Mother-in-law!"

Yu Yao cheered and threw herself into the arms of the beautiful woman, who was Granny Huang.

In Chu Duan's perception, there was a huge amount of power hidden in Granny Huang's body at this time, which was ten times stronger than before.

Huoqi Huang and Nangong Yu saluted, and said excitedly: "Congratulations to my aunt on her promotion to Dongtian." ”

"Congratulations to my mother-in-law on her promotion to Dongtian!" Chu Duan also saluted and congratulated.

Granny Huang smiled bitterly and said with emotion: "Originally, I was already a dying person, who would have thought that now not only will my longevity be replenished, and my bloodline will be traced back to the fire phoenix, but also successfully promoted to the realm of the cave sky." All of this is the credit of Twilight, but this karma is too great, how can I repay it, old woman. ”

"What did my mother-in-law say, you are Yu'er's mother-in-law, that is my mother-in-law, and it would be too much to say that it would be repaid. Chu Duan said with a smile.

Yu Yao sneered: "Mother-in-law, who said that you are old, you are not older than your mother now, you are a great beauty!"

"It's just your sweet mouth. Granny Huang pinched Yu Yao's cheek.

Huoqi Huang and Granny Huang stood side by side, grabbed Granny Huang's arm and said, "Mother-in-law, you see, we stand together like sisters, if Mother knows that you have been promoted to Dongtian, she will be very happy." ”

"It's not big or small, and I still make this kind of joke with my aunt, but it's true that I haven't seen my sister for a long time. Granny Huang's eyes were gentle.

The sister in Granny Huang's mouth is Yu Yao's grandmother, Huoqihuang's mother, they are not only like sisters, but also like Chu Duan and the wine and meat monk Jin Lan.
