There are nine hell lands in the underworld, and the nine hell lands have existed since the opening of the world, and they are where all the negative forces such as death and darkness are formed in the Tianjun Great World.

There are nine Hellland Jedi in the Nine Prison Lands, which were formed at the time of the opening of the world, and one of each of the nine Prison Lands.

The Nine Secluded Lands Jedi have been burial soil since ancient times, and I don't know how many powerful existences have been buried, and it is even rumored that there were emperors who buried their bones in several secluded soils.

For some reason, even the Heavenly Venerable of the Eight Great Underworld Giant Clans turned a blind eye to the Eight Great Dark Land Jedi, and even the powerful and domineering Shura Heavenly Venerable did not bring the blood pool Jedi of the Shura Prison Land into the control of the Asura Clan.

The flesh of the Great Black Heaven is the refinement of the Supreme Treasure Nine Shadow Flesh Fetus created by the Underworld Heaven and Earth, and there are nine secret realms born in the Nine Shadow Flesh Fetus, which are called the Nine Secret Realms, which correspond to the Nine Hellland Jedi of the Nine Helllands.

Every time a secret realm is opened, the combat power of the Great Black Sky will change qualitatively, reaching an astonishing level. That was the power given to him by the secret realm, and it couldn't be guessed by common sense at all, each of the Nine Secret Realms had the ability to be extremely mysterious.

Since the beginning of the world, there have not been many Nine Shade Flesh Fetuses bred in the underworld, otherwise even the Ancient Emperor would not have been able to ask for it.

Chu Duan originally thought that the Great Black Heaven would have to reach Nirvana at about the sixth level, and even step into the Divine Yuan to open the Nine Secret Realms, but he didn't expect him to touch the first Nine Secret Realms so quickly, which was about to open.

Da Hei Tianpan sat in the Lingxiao Heavenly Palace, and asked the lotus platform carved from the stone, and then his consciousness sank into his body and began to open the Nine Secret Realms with all his might.

The Soul Bird Cry Xuan was lying beside Da Heitian, and he got his mother's legacy, coupled with Da Heitian's full cultivation, he has now survived three Nirvana Tribulations, his blood is strong, and his talent has reached the level of a top prince.

The cry was obtained by Chu Duan in the forbidden god realm of the Forbidden Emperor of the Senior Brother, and Chu Duan also asked the senior brother about its origin. Forbidden Heaven told Chu Duan that the ancestor of Cry Xuan was the quasi-emperor of the Soul Bird clan, and he had something to do with the Forbidden Emperor in his previous life.

The Soul Bird Clan was targeted for restraining the Underworld clans, and almost led to their annihilation. The Soul Crying Bird Emperor begged the Emperor to take in his bloodline descendants, and the Forbidden Emperor put some of his bloodline descendants in his own god realm, but he didn't expect to be taken away by Chu Duan, this may be the fate in the underworld.

Cry Xuan is the descendant of the quasi-emperor of the Soul Bird clan, and his mother is a bloodline atavistic ancestor, and his bloodline is a matter of course. What's more, before her death, Cry Xuan's mother passed on her ancestral blood to Cry Xuan, who had not yet been born, and at the same time there was a mysterious white thing, even Chu Duan didn't know what it was.

The mysterious black light circulated on Qi Xuan's body, and Qi Xuan was running his own cultivation exercises, which were obtained by Qi Xuan from that white thing, which fit the bloodline of the soul bird, and was the exercise created by the quasi-emperor.

Chu Duan entered the Qifu Cave Heaven, he wanted to concentrate on improving his Dan Dao attainments, and now the elixir he refined was far from keeping up with his own realm.

With the current background of the Heaven Tribulation Sect, it is nothing to cherish the Divine Pill, not to mention the collection of the Scorpion Worm Nest and the Ice and Fire Yuan Sage, there are many well-preserved Divine Pills among the gains obtained by the Demon Clan's return to the Heaven Destroying Sect this time.

But those divine pills with the best quality are only the best, there is not a perfect quality pill, and the perfect quality pill is also a rare treasure in ancient times. Alchemists are even reluctant to sell pills of this quality, and basically keep them for themselves or give them to their disciples.

Chu Duan himself was able to refine a perfect quality pill, and both the success rate and the quantity were extremely amazing, so he was reluctant to take a pill of lower quality than the perfect one.

In the attic left by the Evil Medicine King, Chu Duan began his alchemy career, and all kinds of heavenly and earthly treasures used in alchemy were continuously sent into the attic.

Chu Duan devoted himself to alchemy, and one by one the pills were formed in the Black Dragon Furnace, if other alchemists knew the success rate of his alchemy and the quality of the pills he refined, he would probably commit suicide in shame.

When Chu Duan was dedicating himself to doing something, nothing could interfere with him, and even Huo Lao was shocked by Chu Duan's will.

Chu Duan's consciousness was full of huge stars rotating in the sky above the sea, and each huge star had a rumbling Dao sound, and the Dao sound contained all kinds of insights about Dan Dao.

These stars were left behind when Dan Weng taught Chu Dui Dan Dao, and the Dan Dao taught by Dan Weng was all-encompassing, and Chu Duan only accepted an insignificant part of it at that time. The rest of the Dan Dao knowledge and perception turned into Great Dao stars and were hidden in Chu Dui's sea of consciousness, appearing at any time when Chu Duan needed them.

Originally, Chu Duan's Dan Dao attainments stayed at the level of top junior Dan Dao masters, but now his Dan Dao attainments are improving every day, and in just ten days, Chu Duan's Dan Dao attainments have been upgraded to the level of top intermediate Dan Dao masters, and he can refine the top mid-grade Bao Dan.

This is naturally because Chu Duan's Dan Dao attainments have already reached a critical point, and only after accumulation can he make such great progress in a short period of time.

Time passed slowly, and about a month later, a spatial passage opened in the Qifu Cave Heaven, and the Great Black Sky with a squatting soul bird on his shoulder walked out of the spatial passage.

At this time, Daikokuten's body exuded a mysterious power, and it looked like a god walking between light and darkness, and it was completely impossible to see through his depth.

Even the Soul Bird Cry Xuan on the shoulders of the Great Black Sky has undergone great changes, and his eyes are deep and sharp, like a sharp sword weapon.

The aura on Qi Xuan's body was more than twice as powerful as it had been a month ago, and in this month, he had once again survived the double Nirvana Tribulation.

When Da Heitian walked into the attic, just in time for Chu Duan to refine a furnace of elixir, seven blue rays of light rose from the Dan furnace and fled in all directions.

Chu Duan didn't look at it, he grabbed it towards the void, and suddenly the seven rays of light seemed to be frozen, and he couldn't escape anymore. If you look closely, you can develop, and there are translucent silk threads flying out between Chu Duan's fingers, and it is these silk threads that imprison the seven rays of light.

After the seven rays of light converged, seven crystalline blue round pills were manifested, and the fat blue round pills rolled in the void, and suddenly turned into seven three-inch tall fat dolls with blue belly pockets that looked exactly the same, and opened their mouths to bite the translucent silk threads.

As soon as Chu Duan pulled the silk thread, the seven fat dolls all fell into the void, and a mysterious force sank into their bodies along the silk thread, and the seven fat dolls were beaten back to their original shape, turning into seven crystal blue pills and falling into the three jade bottles on the ground.

"Congratulations to Daoyou for refining the top-grade treasure pill!"

Da Heitian recognized that the blue pill was an ordinary high-grade treasure pill for healing, which marked that Chu Duan's Dan Dao attainments had reached the level of a high-level Dan Dao master.
