"Thank you, Elder, for your advice. Pen ~ Fun ~ Pavilion www.biquge.info"

Xie Yun bowed and saluted, waved his right hand lightly, and a sword slashed at the door of the Celestial Heart Palace, and in an instant, the palace door rippled like water waves, and the colorful Heaven and Earth Yuan Qi diffused, but it seemed to be blocked by an invisible barrier, and it could not escape from the Celestial Heart Hall at all. Everywhere the sword light passed, the invisible barrier was instantly cut open a gap one person wide, Xie Yun's figure flickered, and he flew by in an instant.

"Folded space!"

Xie Yun was shocked in his heart, the first floor of the Heavenly Heart Hall was extremely wide, and he couldn't see the edge at a glance, it was not a radius of hundreds of zhang seen by the outside world at all, but with the space folding formation, he forcibly intercepted a void and refined it into this seven-story pagoda, this kind of miracle was far from what the power of the Divine Refining Realm could do.

In the Hall of the Heart of the Heavens, the vitality of heaven and earth is extremely strong, but unlike the outside world, the vitality of heaven and earth here is colorful. In the outside world, the essence of heaven and earth is mixed and chaotic, and the five elements are mixed together, and it is extremely difficult to understand the pure artistic conception, but in the hall of the heart of the universe, the essence of the fire element is a stream of fire-colored streamers, pure, crystalline, and blazing, and the essence of the gold element is pure gold, shuttling quickly and incomparably sharp, but the essence of the water element is turquoise, flexible and flexible, and the wisps are intertwined and flowing.

Xie Yun's hands were sealed, slowly urging the Nine Days Fuxi True Qi, and the Fire Yuan Essence Qi that was diffused in the space of the Heavenly Heart Hall quickly surged to Xie Yun's body acupoints, and quickly merged with the Nine Days Fuxi True Qi, the Fire Yuan Essence Qi continued to vibrate, and gradually resonated within a radius of hundreds of zhang, more and more Fire Yuan Essence Qi surged towards Xie Yun, but the other Yuan Qi was squeezed aside.

The fire element essence qi was integrated into the dantian, and it was quickly refined by the fire of breaking the law, and in just a moment, Xie Yun actually felt a trace of fullness from the dantian.

"The Heaven and Earth Essence Qi of the Heaven and Earth Heart Hall is really pure, only the first layer, compared to the Nine Days Fuxi True Qi that I have worked so hard to cultivate, it is only one line, I am afraid that the second and third layers of Fire Yuan Essence Qi can exceed the Nine Days Fuxi True Qi. Absorbing and refining this purest fire element essence is of great help to me to comprehend the mystery of the artistic conception of fire, and the Celestial Heart Hall is known as the first cultivation holy place of the sect, and it really lives up to its reputation. ”

The soul power slowly diffused, and a thunder sword light jumped in his palm, and Xie Yun's body kept shuttling, looking for a rather rare thunder essence.

Boom! Boom! Boom!

The thunder essence showed a pure blue-purple color, and the moment it came into contact with the sword, it suddenly drilled into the sword, and the thunder sword, which was originally only a few feet long, skyrocketed to more than four feet long in an instant, and the tyrannical and domineering thunder aura continued to rise, and Xie Yun's various mysteries about the Xuan Thunder Slash gradually became clear at this moment.

Sitting cross-legged, Xie Yun's eyes were slightly closed, and he carefully experienced the breath of the thunder essence, the purest thunder essence gathered together, it was the thunder, at this moment, it was equivalent to unraveling the thunder subdivisions, allowing Xie Yun to comprehend the mystery little by little, almost every moment, Xie Yun could feel the improvement of his comprehension of the Xuan Thunder Slash.

In order to ensure that the disciples fully comprehend the artistic conception, martial arts are strictly forbidden in the Celestial Heart Palace, and once discovered, the punishment is extremely severe, which will not only deprive the next ten years of the Celestial Heart Palace's opportunity to participate in enlightenment, but even deduct a large amount of cultivation resources. Moreover, every elite disciple only has one chance to enter the Celestial Heart Hall once a year, and once he is injured, he has to leave the Celestial Heart Hall and wait for the next year, which is because no one would be willing to waste this excellent opportunity to comprehend the artistic conception in fighting with others.

Just one day later, Xie Yun got up and flew towards the second floor of the Celestial Heart Palace.

There are many types of essence elements in the first layer of the Celestial Heart Palace, but the only ones that are really helpful to Xie Yun are the thunder essence, the artistic conception of fire, the artistic conception of gold, and the artistic conception of wind, Xie Yun's comprehension on these three paths is quite profound, and the essence of the first layer of the Celestial Heart Hall is not even as pure as Xie Yun's true qi, and there is not much effect of comprehension at all, only the comprehension of the artistic conception of thunder is relatively shallow, and you can get a certain harvest.

The martial artists on the second layer were obviously much less than those on the first layer, as soon as Xie Yun stepped into the second layer, he suddenly felt a shock all over his body, and the rich and pure heaven and earth essence qi was wrapped around Xie Yun's body like a chain, and the fire element essence qi and the golden yuan essence qi came into contact with Xie Yun's body protection true qi, and quickly turned into wisps of essence silk threads, forcibly drilling into Xie Yun's meridians, shaking the five elements to break the true qi.

However, Xie Yun did not stop, his wings spread, and the violent True Qi exploded, the Yuan Qi chain shattered instantly, and the whole person flew into the third layer of the Celestial Heart Hall like a flying golden eagle.

Zheng!

As soon as he entered the third floor of the Celestial Heart Palace, a blue-purple thunderbolt burst towards Xie Yun, Xie Yun took half a step back, and his heart suddenly moved, his right palm was like a knife, and the Xuan Thunder Slash slashed at the purple thunder. This blow fully exploded Xie Yun's seventy percent of his strength, although he did not urge the long knife, but he easily shattered the purple thunder, but after the thunder was shattered, the thunder essence did not disperse, but turned into a streamer and merged into the sword.

Airplanes...... Airplanes......

The hand knife continued to vibrate, Xie Yun waved his right hand lightly, and the sword volleyed into the void, and there was a faint sound of thunder, and the sword suddenly stirred up a pure blue-purple light, as if it had split a thunderbolt.

"I can't imagine that just one blow has deepened my understanding of the artistic conception of thunder so much, and if I want to make such progress in the outside world, it will be difficult to climb to the sky. The best way to comprehend the pure thunder artistic conception is to understand it from the pure thunder essence, and outside the Celestial Heart Palace, I am afraid that such an effect can only be achieved by directly resisting the heavenly thunder. ”

Xie Yun took out the Thunder Knife and kept urging the Xuan Thunder Slash, countless thunderbolts slashed down, but they were slashed by Xie Yun's sword, and the Thunder Essence was wrapped around the Thunder Knife, and immediately re-converged into a blue-purple Thunder Knife.

In the third layer of the Heaven and Earth Palace, the Heaven and Earth Yuan Qi gradually condensed into substance, the Fire Yuan Essence condensed into a jumping flame, the Water Yuan Essence turned into a rushing river roaring by, and the Mu Yuan Essence Qi was like a fragrant grass, dancing in the wind, exuding a strong breath of life.

The degree of purity of each essence element is almost more than five times that of the second layer, the blue-purple thunder condensed by the thunder essence element, each one is comparable to the full strength of the martial artists of the ten peaks of the abyssal sea, compared to Yang Hong, Ke Ling and the others, the difference is only a millimeter, once the ordinary abyss sea realm martial artists enter this place, let alone comprehend the mystery of the artistic conception, even self-protection is a problem, even if it is Duanmu Ce and the spirit wolf, they must be cautious.

In fact, there were only a few martial artists on the third floor of the entire Celestial Heart Palace, and no one dared to use all his strength to urge the martial arts and the impact of the essence like Xie Yun, so he could only carefully urge three or four percent of the force, for fear of attracting too many essence elements and being killed by force.
