The top-grade immortal marrow that was wrapped within the tiger tooth celestial spirit started to gather outside the Immortal Spirit Aperture that was also within the bone marrow. It was swallowed bit by bit by the surging spiritual energy, turning into immortal essence that hovered around the Immortal Spirit Aperture in the bone marrow.

Although this drop of Celestial Essence was not much, every time he refined a drop of it, he feleavy sensation, as though mountains and mountains were continuously pressing down on his back, as though they wanted to crush him. Furthermore, Yang Junshan could only slightly relieve the pressure by circulating the spirit energy within his body unceasingly, but the spirit energy continued to circulate, causing even more of the Celestial Essence to be refined into Celestial Essence.

Finally, the immortal spirit essence that lingered outside the hidden aperture in the bone marrow seemed to have reached the limit that the meridian channels could handle. The refined immortal spirit essence spun and crashed into the wall of the hidden aperture.

BOOM!

An explosion came up beside Yang Junshan’s ears. When he was about to reach the consummate stage of summoning immortal spirits, the refined immortal essence had already impatiently attacked the barrier of the Immortal Spirit Aperture.

Yang Junshan knew that this was because the foundation he had laid was just too dense, it was already not bad for ordinary cultivators to refine only one Immortal Spirit, after reaching the Great Circle of the Immortal Spirit, they would need to store up spirit energy to be able to break through the barrier of the Divine Spirit Aperture and advance to the third level of Mortal Realm.

The key question was whether or not the fusion between celestial spirits and immortal spiritual cavities were compatible with the cultivation technique they cultivated, and this kind of fusion also included whether or not the attribute was compatible, whether or not the type was compatible, and so on. If one were to talk about all of these things, it would be extremely complicated, and each type could more or less influence the refinement of celestial spirits, the only difference being how much it was.

For example, some people had their spiritual cavities in their kidneys, which were made of water, but this person cultivated an earth type technique. Even worse, after exhausting so much energy, he managed to obtain two immortal spirits, one of which was a fire type immortal spirit stone, while the other was a low grade water type immortal spirit sword.

This was only the simplest of the five elements, there were many other things to note, such as the bear gall celestial spirit being nurtured in the gall bladder, and Yang Junshan’s immortal spiritual cavities being also in the gall bladder, it was alsype of compatibility, and so on.

It wasn’t easy for ordinary cultivators to find an immortal spirit to completely fit their own immortal spirit cavities, and most cultivators could only be affected by the negative effects of the various unsuitable methods. Although this kind of influence wouldn’t affect the cultivation of cultivators, it would definitely slow down their rate of improvement.

Regardless of whether Yang Junshan’s two Celestial Spirits were the Tiger Tooth Celestial Spirits that he had plotted, or the Bear Bile Celestial Spirits that he had accidentally obtained, or the even more unexpected top-grade Celestial Essences that were wrapped within the Tiger Tooth Celestial Spirits, for the three of Yang Junshan’s Celestial Apertures, even if they were not perfect, they were still three extremely compatible Celestial Spirits.

Once Yang Junshan finished refining the three types of spirits and reached the peak of summoning immortal spirits, the accumulated rich and powerful foundation that he had was far from what an ordinary cultivator could compare to. At this time, the refined top-grade immortal spirit essence did not even need to be controlled by Yang Junshan anymore.

Propelled by the top-grade immortal essence, the refined essence of the tiger tooth immortal spirit also began to stir. Following which, the spiritual energy in his body also began to rush towards the immortal spiritual cavities in his spine.

Because the two types of immortal spirit essence had simultaneously attacked the Spiritual Aperture, Yang Junshan had no choice but to use a cultivation technique to absorb even more spirit energy into his body, thus allowing the immortal spirit essence to gather even more powerful impact, causing the spirit energy in his meridians to move and stimulate the Immortal Spirit Essence in his body. The Bear Courage Essence continued to vibrate outside the Spiritual Aperture, and in the end, created a wave of energy that struck the wall outside the Spiritual Aperture.

Compared to the fierce impact of the top-grade immortal spirit pith on the barrier of the immortal spiritual cavities and the tiger tooth immortal spirit, the impact of the Bear Bile immortal spirit essence on the spirit cavities could only be described as tepid. It seemed to be somewhat unwilling, but because of the violent turmoil caused by the other two essences and the increasing density and speed of the spiritual energy, he had no choice but to follow the ripples.

Outside his body, because Yang Junshan had started to breakthrough the bottleneck of his third spiritual cavities after summoning his immortal spirit, a large amount of spirit energy in the cave started to gather around him. Furthermore, because the spirit energy in his body was circulating so urgently, the spirit energy in the cave seemed to suddenly run out of demand, and gradually formed a faint vortex around Yang Junshan. Once spirit energy leaked out from the spirit spring, it would immediately gather towards Yang Junshan.

Gradually, because the spirit energy was continuously dispersing from the spirit spring water, the small pond that the spirit spring was in had a layer of faint water mist, and the water mist also gradually surrounded Yang Junshan along with the condensed spirit energy.

Clang!

Seeing that the layer of mist on Yang Junshan’s clothes was about to wet him, a clear bell sound suddenly came out from Yang Junshan’s body, and following this crisp sound, a piece of debris fell onto the ground. The layer of mist was immediately scattered and deformed like a startled rabbit.

After the crisp sound, Yang Junshan’s entire body calmed down once again. It was just that the whirlpool of spirit energy formed with him as the center grew larger, and when it absorbed the spirit energy in the cave, it brought about a light breeze.

The scattered mist gathered once more, and this time, due to the influence of the gentle breeze, the speed at which the mist gathered around Yang Junshan increased by quite a bit.

However, just as this ball of mist was about to be swept into the spirit energy whirlpool, another explosive sound came out from within Yang Junshan’s body. This sound was different from the sound of “Silver Bottle breaking through water” from before, and was even more like a war drum being beaten.

But after the sound, the absorption of Spirit Qi increased again, the Spirit Qi whirlpool formed once again, the Spirit Qi in the pool did not even have time to dissipate, instead, it was directly pulled out from the Spirit Spring Water.

This time, the mist was directly sucked into the spiritual energy whirlpool, and very quickly, half of Yang Junshan’s clothes were drenched. However, at this time, a low muffled sound came from within his body, as if the bowstring of Yang Junshan’s large carved bow was suddenly released, and even the sound itself seemed to carry an invisible force, as it destroyed the third spiritual energy whirlpool. At the same time, it brought about a strange wind that swept through the entire cave.

After a while, when the chaotic Qi in the cave calmed down, the only sounds left in the quiet cave were the gurgling sounds of the Spirit Spring Water gushing out of the pond and the even louder sounds of the Spirit Spring Water gushing out of the ground.

A pillar of white smoke mixed with thick mist suddenly rose from the spring water vapor, rose into the air, and then curved and extended towards Yang Junshan. It then descended right on top of his head, and the spirit energy directly entered his body, the steam formed by the white mist had long since wet Yang Junshan’s entire body.

Yang Junshan never thought that the barrier separating the immortal realms would be broken so quickly. First, it was the high quality essence of the immortal realms that kept on breaking through the barrier with the help of the Wutu Spiritual Art, and soon, the barrier crumbled with a crisp sound.

The surge of immortal spiritual energy instantly filled the opening of the celestial spiritual cavities, not to mention that in the instant the immortal spiritual energy was poured into the immortal spiritual energy cavities, the originally refined immortal spiritual energy began to rapidly fuse with the spiritual energy, and every drop of immortal spiritual energy required a massive amount of spiritual energy to absorb. Thus, the spiritual energy in the immortal spiritual energy cavities expanded rapidly, supporting the opening of the immortal spiritual energy cavities along with it, and the space within the immortal spiritual energy cavities rapidly expanded, double the amount of spiritual energy that had before it opened.

The Tiger Tooth Immortal Spirit Essence began to be assimilated by the Spiritual Energy after it entered the Celestial Spirit Aperture. Although it did not require a massive amount of Spiritual Energy to assimilate it, it still absorbed a large amount of Spiritual Energy, causing the space of the Celestial Spirit Aperture to double in size.

The last one to break through the barrier was naturally the lowest quality of the three immortal spirits, the bear gall celestial spirit. The last one to break through the barrier was naturally the lowest quality of the three immortal spirits, and in the end, the bear gall celestial spirit spirit took advantage of the two other immortal essences to expand the space.

During the process of the opening and expansion of the three immortal spiritual cavities, Yang Junshan only felt that the spirit energy in his body was insufficient, he could only use all his strength to circulate the [Wutu Spiritual Art], absorbing the spirit energy around him as much as he could, but he did not know that the spirit energy in the cave was no longer sufficient.

Perhaps because the spirit energy in the spring was being excessively extracted by Yang Junshan when he was trying to expand his Celestial Spirit Aperture, a chain reaction that no one knew of was produced in the veins of the Western Mountain’s mountain peak. A milky white liquid suddenly gushed out from the spring, and with a muffled “gulping” sound, the surface of the pool exploded, and the milky white liquid was directly sucked dry by the smoke pillar above Yang Junshan’s head.

Just as the liquid spiritual energy was extracted from the spring, a rumbling sound came from deep underground, and the entire cave shook a little, as if Yang Junshan was suddenly awakened from his stupor and opened his eyes. He had actually surpassed the Perfection Stage of summoning an immortal spirit, and stepped into the third level of Mortal Realm.
