"I need a quiet place, a few elixirs, three Dharma protectors, and most importantly, medicinal herbs. "Lu Zhengxuan naturally has all kinds of medicinal materials, at the beginning, in the Mixed Yuan Demon Cave, he got most of the treasures of the Mixed Yuan Demon Dao, and there are even supreme treasures in the Infinite Dragon Ring in his hand, but with the status of the Yun family in the Medicine Immortal City, it is not difficult to get the medicinal materials of Lu Zhengxuan's alchemy.

"It is an honor for my Yun family to come to my Yun family for alchemy. Go and open the forbidden place of the 33rd layer of the secret room, mobilize all the resources in the clan, and buy medicinal materials for the adults. "The thirty-third layer of the secret room forbidden land, even these ancestor-level masters have not been able to enter it, it's not that they can't, but they can't refine the pill in it at all, the flames in it are extremely powerful, hidden supreme mysteries, and have thousands of mantras condensed from the supreme chaos yuan fire, this kind of chaos yuan fire is the three of them together, and it may not be able to suppress it.

"Yes. Everyone immediately went down to do errands, the whole hall fell silent, Lu Zhengxuan said with a smile: "This alchemy, is to see the chaotic primordial fire, the three of you protect the Fa for me, the three of them can follow me to observe my alchemy." And I can also give you a copy of the elixir I have refined. I won't let you suffer. ”

"Thank you for your love. "This is indeed the best opportunity, Lu Zhengxuan can make so many guardian elders surrender, not only because of his powerful skills, but also because of Lu Zhengxuan's terrifying alchemy level.

"Yes. The three elders took Lu Zhengxuan to appear in this thirty-three layers of secret room forbidden land, this secret room forbidden place was extremely terrifying, there were countless medicine pills held up, and it was surrounded by dense formations. Lu Zhengxuan pinched the spell mark in his hand, waved his hand, and cast three guardian spell seals, which were pointed at the three gods of the three people, and immediately turned into red points of light, directly forming a terrifying guardian talisman.

Lu Zhengxuan stepped up, the lotus under his feet, the golden light was shining, one lotus step at a time, the lotus rose with the wind, and it did not fall, but floated in the void, forming thirty-six golden lotus seals, floating in the dark void. Feeling the scorching aura around him, countless Dao seals attracted billowing flames, which instantly exploded and illuminated the entire forbidden land. With a loud bang, he came directly towards Lu Zhengxuan.

In the purple flames, they turned into fierce dragons, and the scorching breath of Rao was that the three people outside the forbidden land couldn't help but tremble, if they were hit by this flame, they would definitely be seriously injured. Lu Zhengxuan waved his hand and grabbed it, pinching the curse seal in his hand, and a huge and incomparably large phantom appeared in the void, this phantom showed the real Pangu true body, no matter how violent the flame was, it couldn't get close. Even the three people in Yunnan were pale and endured, hiding among the golden lotus, not daring to get close. Lu Zhengxuan raised his head, his gaze penetrated through countless formations, and fell on the three ancestors.

The three ancestors bowed their heads in embarrassment, not daring to stare at that gaze. Lu Zhengxuan said lightly: "Wait for your thoughts, this seat is naturally clear." But he who does not know is not guilty. When you see yesterday's Seven Killing Spells, you should understand. "Seven Killing Spells, Rao is Yun family also has many people who died under this terrifying and mysterious power, but they don't have the heart to trace the source of this power at all, and now when they hear Lu Zhengxuan talk about it, they didn't expect it to be performed by this adult himself.

"Sit down. Seeing that the minds of the three people were shaken, a roar, the king and the lion, shook the hearts of the three people. The three of them immediately sat cross-legged on the ground, respectful and calm, protecting Lu Zhengxuan.

A steady stream of Dan Dao medicinal materials was sent to this forbidden place, and Lu Zhengxuan began to prepare to refine the pill. The first is to prepare for the recovery of the Dan River, the second is to crack the power of the Dan Demon and save the evil medicine immortals, and the third is to pass the alchemy this time, understand the origin power of the entire Medicine Immortal City, and prepare for future battles. And to get the mark of the saint, it is also necessary to make this ancient city from revival to strength. The easiest way is to refine an elixir that is different from this world.

"Fire comes. Reaching out and grabbing it, purple flames converged from all directions, lingering at his fingertips into a purple wisp of chaotic Yuan Fire, and the Yuan Fire was surging with brilliance, like a fire dragon. The spirit moved slightly, and the medicinal herbs flew from the void, densely packed, and spread throughout the void.

"Go. The flames flew, turning into purple silk threads in the sky, and burst out directly, indiscriminately hitting each medicinal herb. These medicinal herbs are at least hundreds of thousands of years old, which is very rare outside, but here, it is very common. This ancient Dandao world has existed for countless years, and it has evolved countless mysterious treasures. What is revealed now is only the tip of the iceberg, and what is in Lu Zhengxuan's hands is even more of a drop in the bucket. Countless medicinal herbs were immediately turned into clusters of colorful medicinal liquids under the power of the flames.

This method is very dangerous, but it is extremely challenging for the cultivation of the soul. Lu Zhengxuan indiscriminately controlled these medicinal herbs and protected them from being completely destroyed by the Chaos Yuan Fire, which showed that his soul Dao power had reached a higher level.

The golden elixir exudes wisps of medicinal fragrance, refining the origin of the most precious and pure medicinal materials without damaging the slightest. This hand, only those guardian elders have such strength. Around Lu Zhengxuan's head, thousands of fist-sized balls of various pill liquids floated.

These pills are dazzling and mysterious, and the mystery is abnormal, and they float in the air like this. In an instant, under Lu Zhengxuan's power, a huge golden vortex was formed. In the golden whirlpool, different pill liquids fused and collided, all of which relied on Lu Zhengxuan's soul path origin will to mobilize.

The three of them saw that the golden whirlpool was getting bigger and bigger, and the momentum was becoming more and more ferocious. The power contained in it completely burst out, and even the golden lotus sitting cross-legged was constantly trembling, as if it was about to be destroyed at any time, and the three ancestors outside were even more surprised. Although it was under the protection of many formations, the power of the pill had never weakened, but became stronger and stronger.

"Look, two junior brothers. "They are guarding outside the forbidden land, there is a medicine garden here, and now there is a golden Dan Qi vortex escaping from the formation, directly swallowed by these herbs, and it grew crazy in an instant, and the power of the medicine path in it became more and more calm, but in the time of a stick of incense, the three of them were already under the dense herb leaves, and they couldn't see their figures at all.

"The order went down, the great array was opened, and all the disciples at home began to practice. Don't waste this rare opportunity. "Rao is they have also peeked out a lot of secrets from this golden Dan Qi, Lu Zhengxuan can let the three of them guard, and it is also the opportunity for the three of them.

A day passed, and the entire Yun family's formation was also opened, and all the disciples were indulged in cultivation, enjoying this hard-won opportunity. Lu Zhengxuan was devoted to alchemy and didn't know what was happening in the outside world. His gaze wandered in this huge golden vortex. Pinching the spell mark in his hand, countless rune spell marks were instantly punched out, and he rushed directly into this golden whirlpool.

At present, the power of the elixir has been stored, but the elixir has not taken shape. The origin of the law and the will of the rules contained in the elixir have not been formed.

Lu Zhengxuan had to cast a spell mark every half a month, and different laws were planted into these pills. until it merges with these Dan liquid origin forces to form a new power.

Three months have passed, but three thousand years have passed inside.

Three thousand years of refining the Seven Turns Golden Pill is not enough. However, the power of this Chaos Yuan Fire is strong, and the power of the Fire Dao Origin Power is used to stimulate the due power of these pills. It shortens the time, continuously enhances the original power of the elixir, and stimulates the potential of each elixir.

The spiritual path of the Seven Turns Golden Pill is terrifying, and it already has the power to evolve the Dan Spirit. And the Chaos Primal Fire is such an opportunity. Lu Zhengxuan naturally would not evolve the Dan Spirit at this moment, and the horror would have to cause the entire Medicine Immortal City to shake. However, if it is thrown into the Dan River, it may be able to stimulate the power of the entire Dan River.

Under the collision of purple flames, the huge golden vortex evolved into thousands of scenes, some into phoenixes, some into unicorns, some into real dragons, and some into white tigers. All kinds of wills are really elusive, and the three of them are dazzled, but they don't forget to practice.

This rare opportunity made them more aware of the magnificence of the Dan Dao world, and the golden vortex gradually condensed into a huge Bao Dan, transparent and crystalline, escaping layers of brilliance, illuminating the entire forbidden void. The inside is like this, and the outside has also become extremely spectacular, the huge formation is about to be exploded by this terrifying Dan Qi power, the monks of the Yun family around continue to swallow the power in it, and the medicinal herbs and plants of the Yun family are crazy, completely shrouding this ancient family palace in a verdant greenery.

The three great ancestors didn't dare to practice at this moment, if such a power broke through the formation, they were afraid that it would attract more covetousness.

"What to do, the power seems to be endless, escaping from the forbidden land. Rao is the three of us who suppressed it, and they may not be able to get benefits. ”

"Could it be that the power of the formation is leaked out, attracting the covetousness of many families?"

"With all the guardian elders in charge, those old things can't make any wind at all, not to mention that the power of the Seven Killing Spells that the Lord said before is still there. Once someone destroys it, it will inevitably suffer a catastrophe. Spread out the formation. The three of them glanced at each other, pinched the spell seal in their hands, and immediately opened the formation.

With a loud bang, the huge Aoki Guanghua directly broke through the sky and stood in the Medicine Immortal City, which was thousands of zhang huge. The Dan Dao vitality that escaped was instantly discovered by the powerhouses of Medicine Immortal City, and the Yun family's opening of the formation had already aroused everyone's suspicions, and when the formation was opened at this moment, the strong and powerful Dan Dao will directly made these masters appear in the sky outside the Yun family.

There are hundreds of masters, and these are all long-established figures. The three ancestors of the Yun family did not dare to offend.

"Old man of the Yun family, why is this?" are all Dan Dao kings, and naturally they can see that the momentum and strength of the entire Yun family have changed, especially those huge medicinal materials, which do not have the slightest appearance of raising seedlings, as if they were born like this, as if every medicinal material has grown for millions of years.

"This is due to the alchemy of that adult, and we are helpless. The Guardian Elder and others also knew about it. Adults don't want to be disturbed, and I ask for your forgiveness. ”

"Hmph. "The three ancestors of the Yun family moved out of the guardian elders, and these people were immediately silenced. Now that they feel the power of the Dao Treasure Light, they are all ready to move, wanting to enter the forbidden land of the Yun family to find out.

"There must be something wrong. Dozens of people directly turned their figures, exerting a powerful momentum and flying directly towards the forbidden land, and the light of the forbidden land flew and exploded one after another. The three ancestors of the Yun family couldn't stop it at all, and their figures appeared outside the forbidden land, and said coldly: "What are you doing here?"
