Half an hour later, in the center of the Spirit Hidden Realm, in the canyon where the essence of heaven and earth was rich, an extremely attractive fragrance came out.

At this moment, above the canyon, there are faint clouds rolling, and there is still a colorful brilliance!

Behind a big tree in the central area of the secret realm, Daxian looked at the clouds above his head, his face showed a shocked look, and then he looked at Xiang Yun who was refining pills in front of him!

At this moment, Xiang Yun sat cross-legged, the yellow mangs of Shennong Ding in front of him flickered, suspended in the void, constantly rotating.

Several fire crystals below are also suspended at this moment, controlled by the exquisite cloud power, drawing out a series of sparks, wrapping the Shennong Ding cycle back and forth, like a flame enveloping the Shennong Ding!

At the same time, in the sky above Shennong Ding, the clouds were surging, and a four-colored cloud gradually gathered.

If an alchemist saw this scene, he would definitely be shocked, the elixir that could trigger the vision of heaven and earth must be the best elixir about to be released!

Yunxia has a total of four colors, which proves that what is refined is the best of the four pills!

Legend has it that if you refine more than seven grades of the best elixir, not only will there be a vision of heaven and earth, but there will even be a pill tribulation!

In a moment.

"Ding......!"

With the crisp sound of a pearl falling on the jade plate, Shennong Ding Huangguang was sheng, and a more pure and rich fragrance came out!

The great immortal in the distance, his nose twitched, and he couldn't help but swallow a mouthful of saliva.

At the same time, Xiang Yun, who was sitting cross-legged, was already shining with a faint crystal luster in his eyes at this moment, and his face was calm and indifferent at this moment, and a calm and free temperament emanated from him.

It seems that a grandmaster who has been immersed in Dan Dao for many years, his face is neither sad nor joyful.

When he heard that crisp sound, Xiang Yun just flicked his sleeve robe, and Yun Li held Shennong Ding, and slowly fell in front of him.

As Shennong Ding fell, the faint golden light converged, and the sparkle in Xiang Yun's eyes gradually disappeared.

After the Grandmaster realized that the effect of the Enlightenment Pill had subsided after refining this furnace of elixir, Xiang Yun did not make any moves, and he had been doing it for a long time in place, and his face seemed to be a little confused.

After a while, the confusion on Xiang Yun's face turned into enlightenment!

"Alchemy, I see, is this the effect of the Grandmaster's Enlightenment Pill?"

In the short moment when the Grandmaster realized that the medicinal effect of the pill had disappeared, Xiang Yun's mind was instantly flooded with countless information and perceptions, all of which were all alchemy skills, perceptions, like systematic martial arts, integrated into his heart!

Xiang Yun could clearly feel at this moment that his current understanding of the art of alchemy was not the same as before, as if he had studied the art of alchemy for more than ten years.

This is not only a theoretical understanding, but also can be put into practice, Xiang Yun even felt that if he let himself refine this Crossing Spirit Pill again at this moment, he would also have great confidence that he would be able to refine it successfully, comparable to a fourth-grade alchemist.

Sighing in his heart, Xiang Yun slowly reined in his thoughts, and looked at Shennong Ding, who had been smoked a little black by the previous seven explosions in front of him.

Xiang Yun slowly untied the lid of the tripod, stretched out his hand, and a turquoise pill flew out and fell into his palm.

Looking at the Spirit Crossing Pill in front of him, Xiang Yun's face couldn't help but show a hint of consternation.

The Crossing Spirit Pill in front of him, the whole body is as green as jade, and it releases a faint brilliance, the medicinal fragrance is fragrant, and the surface of the pill is still growing, like a vein-like golden silk thread, which is obviously different from the ordinary Crossing Spirit Pill.

But what really surprised Xiang Yun was that the physique of this spirit pill was a little surprisingly large, it was the size of an egg, several times larger than a general pill, if it was used to swallow it, it was estimated that it would choke people to death.

Could this be the 'Super Crossing Spirit Pill'?" Xiang Yun suddenly burst into his mind.

Although he didn't know why the appearance of this Crossing Spirit Pill was so peculiar, but the pill refined by the Grandmaster Realm even led to the vision of heaven and earth, and Xiang Yun didn't believe that there would be any problems.

At this time, the great immortal in the distance had already followed the aroma and came to Xiang Yun's side, staring at the pill in Xiang Yun's hand with his eyes, swallowing his saliva, the little guy said.

"Huh...... Is this the elixir, can you give it to me...... Take a look?" said this guy who couldn't wait to get started.

Xiang Yun put away the pill and dispelled this guy's crooked thoughts.

"Can you survive this?"

"You're going to survive here?"

"Otherwise, would you go out and cross the catastrophe in front of that big python?" Xiang Yun said angrily.

Daxian rubbed his cheeks, thought for a moment and said.

"There shouldn't be a problem, I'll take you to find an area where the natural formations are sparse, as long as the Thunder Tribulation doesn't affect these formations, it should be fine. ”

"Okay, take me now. ”

When Daxian heard this, he said with a puffed waist.

"Okay, after refining the elixir, tell me the story!"

"Uh......" Xiang Yun froze when he heard this, where did he have time to tell a story to this little thing now, but it seemed that if he didn't send it, the little guy wouldn't lead the way.

After hesitating for a moment, Xiang Yun entered the storage ring with his mind, and after searching around, a smile finally appeared on his face.

In the storage ring, although there is no storybook, there is still a certain kind of picture album compiled by Qin Fengcheng, which comes in handy at this moment.

"Hey...... Little one, I've got good things for you to show here, and if you take me there, I'll give them all to you!"

"Good stuff, are they books, are there any good stories?"

"Of course, it's even more exciting than those stories!" Xiang Yun patted his chest and promised.

Upon hearing this, Daxian looked at Xiang Yun with some disbelief.

"You didn't lie to me?"

"I can't lie to you, I can't ......"

Thinking that he would be a catastrophe later, it would not be good if it really came true, Xiang Yun hurriedly changed his words.

"Ahem...... Promise not to lie to you. ”

"Oh well. ”

Daxian still chose to believe Xiang Yun, and then took Xiang Yun to the west, a big mountain, in a clearing halfway up the mountainside.

The natural formation here is the most sparse, and there is almost no danger within a radius of dozens of zhang, which is the most suitable place for Xiang Yun to cross the tribulation.

Xiang Yun was also quite satisfied with this, and without Daxian opening his mouth, Xiang Yun casually took out a thick stack of books and threw them to Daxian.

"Wow...... So many storybooks?"

When Daxian saw the book that was half a cut higher, his eyes suddenly lit up, like a treasure!

Seeing this, Xiang Yun was thinking in his heart, whether he had taught the child badly, but after thinking about it, this guy was really old, older than his grandfather.

And it's not human, so it's estimated that looking at these things is similar to humans looking at the 'animal world', but it doesn't matter.

Then, Daxian ignored Xiang Yun, holding a stack of picture albums, and ran away in a hurry, leaving only Xiang Yun in place.

And Xiang Yun did not hesitate, glanced around, and directly took out two thousand low cloud crystals and piled them up around him, and then Xiang Yun also sat cross-legged on the spot.

Now that the elixir and cloud crystals are all ready, it is imperative to break through the earth and cloud realm, otherwise you don't expect to leave here!

Whether it can break through or not, it depends on this time, Xiang Yun wants to finish his work in one battle!

Just closed his eyes and meditated for a while, Xiang Yun's gaze became calm as water, and his mind no longer fluctuated.

Xiang Yun raised his head and took this egg-sized elixir!

Fortunately, the Crossing Spirit Pill melted in the mouth, and the pill turned into Jin Ye and went down the river, otherwise Xiang Yun really wouldn't be able to swallow it.

Not long after swallowing the pill, Xiang Yun felt a familiar feeling of hot expansion in his lower abdomen, and he did not panic, knowing that this was the medicinal power of the Crossing Spirit Pill, and the dantian would carry out another round of expansion.

Xiang Yun immediately ran the merit creation technique, the acupoints of the whole body were opened, the cloud crystals around him were pulled, and the rich cloud power was revealed, and along the pores of Xiang Yun's body, they swarmed in!

These cloud forces converged into the dantian, and Xiang Yun clearly felt that his original dantian world was expanding rapidly again at this moment!

Opening up the dantian is not a fun thing, the swelling pain doubles, and the sharp pain like a pinprick makes Xiang Yun's complexion change slightly, but he is not worried.

With his previous experience of taking the Doling Pill, he knew that all this was normal.

However, after a while, Xiang Yun didn't think so, because this pain was actually increasing, and with the rapid inhalation of cloud power, the dantian still maintained a trend of crazy expansion.

At the same time, a violent scorching sensation came, giving Xiang Yun the feeling that there was a volcano in his body, and he was tormented!

"Shhh...... How so!"

Xiang Yun's expression changed, and he felt that the pain he was suffering at this time was far greater than when he had taken the first Crossing Spirit.

What's more, this kind of torture continues to increase, and at this moment, there are already green tendons on his forehead, and cold sweat is flowing!

Xiang Yun faintly guessed that this might be related to the medicinal effect of this Crossing Spirit Pill, how could the best elixir refined by a grandmaster-level alchemist be naturally stronger than ordinary elixirs!

Almost a moment ago, Xiang Yun's face was as pale as snow, his whole body was trembling slightly, and his clothes were completely soaked.

This sense of torment was still increasing, and the opening up of the dantian had still not reached the limit, and the cloud crystals around him had been exhausted in just a few moments!

"Damn, how long is it going to be opened!"

Holding back the pain, Xiang Yun waved his hand, directly took out five thousand low-grade cloud crystals from the storage ring, and continued to open up the dantian until it reached its limit!

If it weren't for Xiang Yun's forging realm having reached the 'middle stage of the Five Visceral Qi Realm', if he was replaced by other half-step Earth Cloud Realm martial artists, absorbing such a large amount of cloud power, the dantian would have expanded violently, and he was afraid that he would have exploded and died long ago!

"It's coming, it's about to reach its limit!"

Xiang Yun could faintly feel that his dantian had been expanded countless times, and at this moment it finally began to slow down, Xiang Yun gritted his teeth, and absorbed the surrounding cloud power more and more frantically!

"Humph......!"

With a cold snort, Xiang Yun's body was full of qi and blood, and the robes on his upper body were instantly shattered, revealing a well-proportioned and lean torso.

Xiang Yun's whole body was wide open, and the cloud power poured in wildly, and the dantian had transformed from a lake to a river and sea at this moment, which also indicated that in the future, his cloud power would be far superior to ordinary people!

Xiang Yun couldn't help but feel a little happy in his heart at this moment, fortunately he used the Grandmaster Realization Pill to refine a Super Crossing Spirit Pill.

Otherwise, I'm afraid that even if I take a few ordinary spirit pills one after another, it won't be enough to open up my dantian to the limit!

This medicine is really fucking fierce!

Time passed minute by minute, seeing that most of the thousands of low-grade cloud crystals in Xiang Yun's body had been lost, Xiang Yun's body was already a little unable to support it, and he began to crumble.

"Buzz......!"

Finally, with a buzzing sound, Xiang Yun was shocked.

A momentum that was several times stronger than his previous one suddenly burst out from Xiang Yun's body!

This is a sign of the success of the dantian development, but all this has not been completed, and the success of the dantian development is only the first step.

The next thing is to induce the heavenly thunder and refine the physical body, only by experiencing the thunder tribulation, being reborn, and condensing the earth pill, can he be the real powerhouse of the earth cloud realm.

"Roar ......!"

At this moment, Xiang Yun raised his head to the sky and let out an angry roar, and the cloud strength and blood in his whole body suddenly boiled, and an astonishing momentum soared into the sky!

In an instant, the sky above the canyon was surging, and the sky and the earth changed color.

A dark cloud quickly converged over the canyon......
