Under Xiao Hei's auspices, every pill in this grand auction was successfully auctioned off.

Most of the seven-rank pills were exchanged for seven-rank pills of the same rank by those monks who had been rewarded by the flowing clouds.

And those three eight-rank pills were basically digested by these Douzun powerhouses, of course, these people would definitely not exchange the pills given by Liuyun.

After all, the quality of these three pills of the old man Mu Gu is far inferior to the Bodhi Dan, Pozun Pill, this eight-grade high-grade pill.

During the entire auction process, Liuyun received many prompts from the system, and almost every prompt lifted Liuyun's spirit.

Most of those seven-rank pills were returned ten thousand times the nine-rank pill, a few returned ten thousand identical seven-rank pills, and those eight-rank pills were all returned with a nine-rank pill.

At this moment, in the system space of Liuyun, there were three pills that had reached the level of the Nine Rank Xuandan, and the number of Nine Rank Pills was as many as fourteen, and the extra Seven Rank Pills were tens of thousands.

Looking at the three most dazzling pills in this pile of pills, Liuyun's mood couldn't be calmed down for a long time.

The Nine-Rank Xuandan is one level higher than the Nine-Rank Treasure Pill, and in this Douqi Continent, it is estimated that even the Medicine Clan who inherited the bloodline of the Medicine Emperor will not be able to take out three Nine-Rank Xuandan.

This kind of powerful pill is not something that can be refined at will, not only is the pill extremely scarce, but also many extremely precious medicinal materials, and the formation of the pill also needs to absorb an extremely large amount of heaven and earth energy, so it does not mean that whoever has the strength to refine the Nine Rank Xuandan can achieve mass production of the Nine Rank Xuandan.

A top alchemist, in his lifetime, is already extremely lucky to be able to refine a nine-rank Xuandan.

There were once ancient records that in ancient times, as long as there was a place where the Nine Rank Xuandan was born, it was almost a thousand miles of barrenness, because all the energy of this heaven and earth was absorbed by the pill.

Liuyun remembered that in the original medicine clan pharmacopoeia, Elder Wanhuo, Old Man Shennong, Soul Xuzi, and Xiao Yan only refined one of the Nine Rank Xuandan, even in a place with abundant energy like the Medicine Clan's Medicine Mountain, only one Nine Rank Xuandan could be refined, and it can be imagined how difficult it is to refine a Nine Rank Xuandan.

"Lord Yunmeng, there are still many things waiting for us to go back and deal with in Danta, so we will stay for a short time."

After the auction ended, the two Danta giants, Xuanyi and Tianleizi, quickly said goodbye to Liuyun.

"Well, the two seniors will have a period later." For the departure of the two, Liuyun did not stay.

After the departure of the two giants of Danta, many others also chose to leave the city, but nearly a quarter of them remained in the city after the auction.

Some of these people want to continue trading with people in the Bone City, or get to know some people, while others want to join the Heaven and Earth Alliance.

These things, Liuyun temporarily handed over to Fu Fan to deal with.

And he himself returned to a large hall.

"Yun boy, when you go out this time, you still try not to expose your identity well, with the financial resources you show, even the sage will covet it."

In the main hall, knowing that Liuyun was here to say goodbye to him, the Heavenly Fire Venerable couldn't help but remind.

"Don't worry, I'm in control!" Liuyun nodded and replied lightly, and then, in the middle of his mind, a purple circle of light appeared in the center of the hall, and then, a red figure without any breath on his body appeared in front of Liuyun and Tianhuo Venerable.

"It's!"

The moment he saw this red figure, although the Heavenly Fire Venerable couldn't feel the strength of the other party, but, with his intuition, he knew that the strength of this red figure that suddenly appeared was probably several times stronger than the Second Heavenly Venerable of the Soul Hall that came that day.

"Old man Yao, this is a heavenly cow!"

Liuyun briefly introduced a sentence to the Heavenly Fire Venerable, and then walked over to the Heavenly Bull and took some things.

After receiving these things, the figure of the Heavenly Bull immediately disappeared into the main hall.

"After I leave, you will take this jade cylinder with you, and if the Heaven and Earth Alliance encounters a life-and-death crisis, you will crush this jade cylinder."

Liuyun took out a red jade cylinder and handed it to the Heavenly Fire Venerable.

"Yun boy, I finally see the powerhouse of the monstrous force behind you again!"

Taking the jade tube, the Heavenly Fire Venerable said with some excitement.

"Old man Yao, in time, maybe you can become such a strong man!"

Patting the Heavenly Fire Venerable on the shoulder, Liuyun suddenly took out six jade bottles of different colors and handed them to the Heavenly Fire Venerable.

"What is this?" Seeing the jade bottle that Liuyun suddenly handed over, the Heavenly Fire Venerable said suspiciously.

"The black jade bottle contains a Bodhi pill, another pill, you take it in the order of white, blue, green, orange, and gold, with these six pills, you may be able to break through in a short period of time to become a Dou Sheng's powerhouse." Liuyun explained.

"Fighting Saint Strong!"

Hearing Liuyun's words, the Heavenly Fire Venerable looked at the jade bottle, his eyes full of heat.

This jade bottle looks like it contains an elixir, but, what kind of elixir can make Yun Boy say such a bold word as making people break through and become a Dou Sheng?

"Okay, I'm leaving, I hope to come back next time, you old man has been called the Heavenly Fire Sage!"

Just as the Heavenly Fire Venerable was thinking, Liuyun's figure gradually disappeared into the main hall.

"Gone!"

Seeing the empty hall, the Heavenly Fire Venerable sighed.

Then, he began to open the white jade bottle.

"Douzun Dan!"

According to the order of taking it explained by Liuyun, this Douzun Pill should only be the lowest grade of the pill.

The eight-grade high-grade pills are only at the bottom, so what kind of terrifying level should the remaining four pills become......

After a while, Liuyun's figure was already within a hundred miles of the Bone Transformation City.

Because the Star Array blocked the space, the spatial wormhole was not activated in the Bone Transformation City.

Therefore, at this moment, the flowing clouds rushed straight towards the nearest spatial wormhole city with access to the middle region.

Of course, this time when he went out, Liuyun temporarily chose to hide his identity and not let others know that he had gone to the Central Domain at this time, otherwise, if the news reached the Soul Palace, he would be stuck by that group of people at any time.

Soon, Liuyun came to his destination, and the interesting thing is that the income obtained from the city's spatial wormhole was to be handed over to the Heaven and Earth Alliance.

Like the others, Liuyun also paid the fee for using the spatial wormhole, and then, he came to the pitch-black and deep spatial passage again.
