The Heavenly Realm opened up by Tianzun was vast and boundless, and Chu Duan and Nangong Yuyao were in a hurry while recovering from their injuries. On the way, Chu Duan encountered countless heavenly and earthly treasures, and many legends of heavenly materials and earthly treasures were extinct in the ancient era, perhaps only a very small number of ancient Taoist medicine gardens inherited from the ancient era, or some dangerous Jedi can be seen.

Chu Duan was not polite, all the heavenly and earthly treasures that he could get his hands were swept away by him, but there were also many heavenly and earthly treasures that even he didn't dare to approach, once he got close, there was a great danger in his heart, as if there was a terrible murderous thing hibernating.

Using the heavenly and earthly treasures in his hand, Chu Duan refined more than a dozen kinds of pills to recover his injuries, and he recovered from the injuries on his body in less than a day.

In addition, Chu Duan also refined various pills for Yu Yao, including pills to improve cultivation, pills to break down realm barriers, antidote pills, pills to restore the mind, etc., the grades range from the middle grade of the treasure level to the upper grade of the Dao level, and the quality is all at the perfect level.

What Chu Duan didn't know was that everything he did fell into the eyes of Yu Butterfly and Du E, who were guarding at the foot of the Spring and Autumn Mountain, they didn't expect Chu Duan's Dan Dao attainments to reach such a state, and even perfect quality pills could be refined at will.

Perfect quality elixirs are extremely rare in any era, and alchemists can only rely on luck to refine perfect elixirs without a trace of erysipelas, and the odds are outrageously low. It is precisely for this reason that the price of perfect quality pills has always been high, often twice as expensive as the best pills of the same grade, but they are still priceless and unmarketable.

In the process of collecting the heavenly and earthly treasures, Chu Duan and Yu Yao found that the heavenly materials and earthly treasures they encountered became more and more precious, and the essence of heaven and earth in the air became more and more rich and heavy, which also verified Chu Duan's idea that they were going in the right direction.

There was also a sunset and moonrise in the Shattered Heaven Realm, and it took more than ten days for Chu Duan and Yu Yao to approach their destination, and Yu Die and Du E had been waiting for them at the foot of the mountain for more than ten days. Although more than ten days was not even a flick of a finger for their long life, both of them had been the existence of the Megatron Heavens, how could ordinary people make the two of them willing to wait here for more than ten days.

However, the two of them did not have the slightest impatience, the person who came here was the disciple of that adult, and if it weren't for the fact that the adult came against time to help, they would not have been able to survive through several eras to the present.

All the beings in the Shattered Heaven Realm owe the cause and effect to that adult, and naturally they also include the two of them, so the two of them are willing to wait here.

Chu Duan stopped, looked not far away and said, "Yu'er, we've arrived!"

Yu Yao followed Chu Du's gaze and saw that there was an empty area in front of her, without any buildings, not even a single flower or plant.

Chu Duan stepped forward and saluted: "Junior Chu Duan, thank you Spring and Autumn Butterfly Mother for your help, come to see you!"

Yu Die's eyes were shocked and said, "He was really found by him, and how did he know that it was Venerable who helped him?"

"Let's go, go and meet him in. "Doedo.

The void twisted and gave birth to ripples, and the originally empty place suddenly blurred, and a majestic sacred mountain stood in front of him, so rich that the power of heaven and earth could not be dissolved, mixed with a refreshing medicinal fragrance.

Yu Yao suddenly snorted, the breath on her body floated, and the blazing red lotus holy flame turned into a sea of fire behind her, and a huge red lotus swayed in the sea of fire. The red lotus blooms, a vermilion fire feather with a slender and noble body, and a divine bird with a fierce and domineering gaze that resembles a phoenix.

These days, Yu Yao was hurrying with Chu Duan, and at the same time, she was also seizing the time to cultivate, plus Chu Dui specially refined the elixir for her, which was in line with her cultivation, and her body refining and qi refining cultivation had already reached the peak of the Shenyuan First Level.

At this time, she suddenly inhaled the power of heaven and earth and the medicinal fragrance in the air into her body, which suddenly made her unable to suppress her cultivation, and at this time, she was being promoted from the first level of the divine yuan to the second level of the divine yuan, and it was the body refining and qi refining that ushered in a breakthrough at the same time.

Even if it is gradually recovering today, and the breakthrough is no longer as difficult as it was in the era of the end of the law, it usually takes four or five years for other monks to break through from the first level of the Divine Yuan to the second level of the Divine Yuan.

Even if it is Tianjiao, whose cultivation speed surpasses that of ordinary monks, coupled with precious pills and other treasures that assist in cultivation, it will take at least half a year to break through.

This refers to the premise of not harming one's own cultivation foundation, otherwise there are too many ways in the cultivation world to promote cultivation in a short period of time, but doing so is tantamount to self-destruction of the future, and at a certain point, it will not be able to take a step forward.

Although it was only half a month for Yu Yao to break through to the Divine Yuan First Heavy, after she broke through the Divine Yuan Realm, she entered the Holy Fire Avenue projection cultivation in the Heavenly Flag, and that Holy Fire Avenue was not the Tianjun Great World but the projection of the Holy Fire Avenue of the Eternal Universe. The Holy Flame Avenue of the Tianjun Great World is only a part of the Eternal Universe Sacred Flame Dao, and as a pure-blooded Vermilion Bird, Yu Yao is naturally compatible with the Holy Flame Dao.

Yu Yao, who had cultivated in the projection of the Holy Flame Avenue in the Eternal Ancient Universe, had a more advanced understanding of the Holy Flame Avenue at this time than ordinary Cave Heaven Cultivators, and naturally there was no such thing as an unstable foundation, or even a terrible foundation that was stable. If it weren't for the deliberate suppression of cultivation, it would be very possible to be promoted to the third and fourth levels of the Divine Yuan in the past half a month, and it would not affect the foundation in the slightest.

Monk breakthroughs are often accompanied by crises, but Chu Duan is well aware of Yu Yao's situation and has no worries. Soon after, the aura on Yu Yao's body suddenly climbed a lot, the red lotus in the sea of fire became more delicate and huge, and the vermilion bird in the red lotus was also more powerful. The vision behind him slowly dissipated, Yu Yao smiled, and the improvement of the realm was always a happy event.

Yu Die and Du Er glanced at each other, and with their realm and eyesight, they could naturally see that Yu Yao had broken through the Shenyuan Realm not long ago, and now she had broken through again, but the foundation was too solid and stable, that is, they did not have such a solid foundation in the same realm back then.

"Heaven Destroying Sect Chu Duan has seen two seniors!" Chu Duan saluted to the feather butterfly and Du Wo who appeared with the majestic divine mountain in front of him.

"Nangong Yuyao of the Nangong family has seen two seniors!" Yu Yao also bowed.

Yu Die and Du Er didn't dare to hold it up, and saluted back to Chu Duan: "Spring and Autumn Butterfly Clan Feather Butterfly, Immortal Golden Cicada Clan Du Er has seen Dao Zun disciple!"

Chu Dui's face was not shocked, but Yu Yao beside him changed his face greatly, and his heart set off a turbulent wave. Before entering the Broken Heaven Realm, Yu Yao deliberately went to the Clan's Library Pavilion to check the history of the Zerg, and the Spring and Autumn Butterfly Clan had a Great Emperor in addition to the Spring and Autumn Butterfly Mother, known as the Feather Butterfly Emperor. In addition to the Immortal Heavenly Venerable, the Immortal Golden Cicada clan also has a Great Emperor, known as the Emperor of Doom.

After Feather Butterfly and Do'e became the emperors of the two emperors, in order to show respect, it was impossible for other Zerg to use this name anymore. According to the secret records of the Nangong family, the Feather Butterfly Emperor and the Emperor Du'er disappeared in the battle of the destruction of the Zerg, and there was no trace of these two emperors in the world in the years to come.
