Outside the Nirvana Immortal Cave, Chu Duan and Yu Yao's eyes were complicated, and the chaotic realm re-turned into a light wheel and hung behind Chu Dui's head, while the Phoenix Heavenly Maiden had already left. Knowing that the news that Zhutian Immortal Venerable was still alive was too important for the Phoenix Heavenly Maiden, even if she gained nothing in the Open Heaven Relic after that, it would not be in vain.

"Brother Chu Dui......" Yu Yao looked at Chu Dui and stopped talking.

Chu Duan understood what Yu Yao meant, grabbed her hand, and comforted: "Out of the Open Heaven and Earth, I will order Bing Huo to go to the Phoenix Clan and give a gift, no matter what, this time it is indeed us who take advantage." ”

"Hmm!"

Yu Yao nodded, she could see that the Phoenix Heavenly Maiden had a deep sense of affection for Brother Chu Duan's elder brotherhood, otherwise she would not have given up this immortal cave because of a piece of news. But Yu Yao and Chu Duan can't take this affection for granted, otherwise both Chu Duan and Yu Yao can't help it, and they can only make up for it in the future.

"By the way, Yu Yao, how could this vine follow you?"

Chu Duan was a little curious, the origin of this vine was extremely mysterious, and it was suspected that it was a treasure born in the chaos and vastness, and it already possessed spirituality and wisdom.

Yu Yao glanced back at the vines circling behind her and said, "I don't know what's going on, but I accidentally broke into a valley and encountered this vine in that valley. Then I sat under the vine for a while, and suddenly a red gourd fell into my arms, and the whole vine rose up and followed me. ”

After listening to Yu Yao's words, Chu Dui's face was weird, he had worked hard to get three gourds, and Yu Yao not only easily got the red gourd, but also got the initiative of the entire vine to follow, is there any heavenly reason?

However, Chu Duan was very happy, this vine was very extraordinary, especially the chaotic air flow wrapped around the vine, which was the power that Chu Duan was afraid of, enough to protect Yu Yao in the Open Heaven and Earth.

"Scorpion, you and the Sky Splitting Storm Ape are here to forbid anyone to come within ten zhang of the Immortal Cave, otherwise there will be no forgiveness!" Chu Duan commanded.

"Yes, Lord!" Scorpio bowed in order.

After arranging it, Chu Duan took Yu Yao's hand and flew into the Nirvana Immortal Cave, and the rich flame essence evolved into the form of the legendary flame beasts such as the phoenix, the golden crow, and the vermilion bird.

Nirvana Immortal Cave is not too deep, from the entrance down less than a hundred zhang to the bottom of the Immortal Cave, the bottom of the Immortal Cave can have a circle of ten zhang, the ground as a whole seems to be cast by transparent red gemstones.

In the center of the bottom there is a pool of square circles, the pool is not known how deep, the pool is completely filled with the divine liquid formed by the essence of liquefied flames, and a lotus-like divine object with a radius of three feet, like a red diamond, blooms in the divine liquid.

Chu Dui's divine consciousness fell on the lotus-shaped divine object, and he felt that the unimaginable flame essence was surging in the lotus-shaped divine object, this treasure was completely condensed from the pure flame essence, and the degree of preciousness was unimaginable.

Yu Yao was about to approach the lotus-shaped artifact when a red light suddenly flew out of the pool of Zhang Xu Fangyuan, and the red light rushed towards Yu Yao's face as fast as lightning. Before the red light arrived, a terrible burning sensation had already come to her face, and Yu Yao couldn't react at all.

At this moment, Chu Dui's Chaos Realm opened, instantly protecting Yu Yao, and the red light seemed to know the power of the Chaos Realm, and retreated back at lightning speed.

Yu Yao was shocked, only to see a snake-shaped beast that could be a foot long, the thickness of ordinary chopsticks, and a red flesh crown on the top of its head entrenched on a lotus-shaped artifact. The snake-like beast's blood-colored film-like flesh wings vibrated violently near its head, making a piercing sound, as if warning Chu Duan and Yu Yao.

"Heavenly crown snake!" Yu Yao exclaimed, calling out the name of the snake-shaped beast.

The fierce reputation of the Heavenly Crown Snake is even better than that of the Dragon Ant, this ancient fierce creature has also existed since the beginning of the world, although the ancestor is not born of the innate divine of the Great Dao, but it is conceived by endless fire. Legend has it that in the original mythological era, the oldest and most powerful celestial crown snake fought with Xiangliu Tianzun, the ancestor of the Xiangliu clan, and repelled Xiangliu Tianzun.

You must know that although Xiangliu Tianzun at that time was immortal before he was proven, in the final analysis, he was also an innate divine born with the Great Dao of Poison, and he was born with the combat power of the Emperor Realm. Even so, it is still not the opponent of the old snake, which shows the strength of the old snake.

It's a pity that the ancient Heavenly Crown Snake offended a ruthless person in the Innate Divine and was killed by that ruthless man and several friends, otherwise it would very likely become a member of the immortals.

The heavenly crown snake was born because of the fire, the nature is ferocious and tyrannical, and the place where it passes is often thousands of miles away, causing the rivers and lakes to dry up and the earth to dry up, and countless creatures die tragically, so it is difficult to reproduce by the way of heaven, and there is almost no record of this kind of murderous thing being born after the ancient times.

The Nangong family occupies the fire domain, and the refining world Tianzun is immortal with the Great Dao of Fire, so the record of fire is the most comprehensive in the clan. As the imperial daughter of the Nangong family, the relationship with Chu Duan is not a secret, so Nangong Yuyao can casually flip through the ancient books and secret scrolls in the depths of the patriarch's scripture pavilion, which contains records about the Heavenly Crown Snake.

Chu Duan didn't dare to take it lightly after knowing the origin of the Heavenly Crown Snake, he felt a strong threat from the Heavenly Crown Snake, this Heavenly Crown Snake's combat power in this Heaven Opening Relic was not under the Night Demon Venerable who possessed the Night Pathless.

"Yu Yao, I'll deal with it!"

Chu Duan controlled the Chaos Domain to protect Yu Yao, and walked outside the domain alone, although this fierce creature was strong, it couldn't stop him.

Yu Yao really wanted to fight side by side with Chu Duan, but she knew that there was a huge gap between her combat power and the Heavenly Crown Snake, not only would she not be able to help, but it would distract Chu Duan from taking care of herself, so she stood quietly in the Chaos Realm.

Seeing Chu Dui fighting fiercely with the Heavenly Crown Snake, Yu Yao quietly clenched her fists, she had to hurry up and become stronger, otherwise the gap with Chu Duan's brother would only get bigger and bigger. This Nirvana Immortal Cave is an earth-shattering creation for her, and with the help of the infinite flame essence in the Immortal Cave, she is reborn and completely sets foot in the realm of immortality.

Chu Dui's battle with the Heavenly Crown Serpent lasted for a long time, mainly because Chu Duan was afraid of destroying the lotus-shaped artifact born of the Flame Spirit, so he didn't dare to use all his strength, and he would inevitably be restrained.

In addition, this Heavenly Crown Snake has been entrenched in this place for I don't know how many years, although it cannot be cultivated under the forbidden laws of the heavens, its physical strength has reached an astonishing level, which makes Chu Duan's fists stained with blood.

However, the Heavenly Crown Snake was invincible to Chu Duan after all, and was injured by Chu Duan's soul with his ice spirit cold pupils, and severely injured his body with his heavy mountain fist and interception fist, and was already dying on the ground at this time.

Chu Duan originally wanted to kill the fierce creature of the Heavenly Crown Snake, but was stopped by Yu Yao in time, if this kind of creature can be subdued, and it can be cultivated well, it will definitely be a great help in the future.
