How did a bastard like him become an immortal?

The two ventured deeper and indeed sensed the overwhelming malevolent energy emanating from the formation.

Ahead came the mournful sound of numerous chains being dragged, like the wind blowing through a cave and across a skull grave.

Turning past a jagged stone pillar, the sight before them made both of them hold their breath.

In the center of the circular cave with a diameter of ten zhang, the dark blue spiritual energy gathered into a vortex, but it was surrounded by nine Yang God Pillars engraved with blood-red runes.

Each bronze pillar was wrapped with black chains, the ends of which were pierced by hundreds of skeletons, their empty eye sockets flickering with green phosphorescent flames. These skeletons wailed incessantly, yet their souls had already been stripped away.

"Using the living soul as a guide and the earth's veins as a furnace... This is a variant of the ancient Nine Nether Soul Refining Array. Does the Yang God Palace still possess such an ancient, incomplete formula?"

Suddenly, something jumped in Li Muyun's mind, and Rabbit God's voice was unusually serious.

Just from the name, this formation must be some kind of extraordinary array.

Indeed, Li Muyun had just looked around and could only see a trace of the array's ripples.

If a formation master cannot determine the location of the formation's core, it means that the formation is far beyond his ability to resolve.

Li Muyun was not proficient in the art of formations. Compared to his swordsmanship, he was more focused on swordsmanship. Faced with such an ancient and incomplete formation, he was naturally at a loss.

Zhao Tianming felt a chill run down his spine at the sight before him. These densely packed skeletons all possessed incredibly powerful auras, yet without exception, their souls had been stripped away.

This demonstrates the ferocity of this grand formation. Yet, this very formation guards the pulse gate; without breaking through it, one is powerless to enter the pulse gate.

"Brother Li, your mastery of array formations is quite remarkable. Are you capable of breaking through such a powerful array?"

Zhao Tianming looked up and could only place his hopes on Li Muyun beside him.

Although he was skilled in observing qi and his location exploration skills were exceptional, this brightly lit array was right in front of him.

Only this one passageway connects to the others; the other major meridians are either guarded by demons or are extremely hidden.

"Hmm... this formation is somewhat difficult, but it's not completely unbreakable."

Li Muyun appeared to be deep in thought, staring intently at the distant bronze pillar, but in reality, he was desperately seeking help.

"Rabbit God, can you break this formation?"

The Rabbit God in the divine consciousness also became interested, staring at the Yang God Pillar in the distance, its snow-white ears twitching incessantly.

"This Nine Nether Soul Refining Array is incredibly powerful and extremely malevolent. It forcibly strips and extracts the souls of cultivators. In ancient times, even many great gods could not escape its clutches. Although this is now a remnant array, its ferocity remains undiminished."

Li Muyun looked up and saw that hundreds of skeletons were imprisoned on the nine Yang God Pillars. These skeletons had been on the Yang God Pillars for countless long years. Their bodies had become magnificent, but they still retained their minds and suffered greatly.

This kind of evil magic made his scalp tingle. The soul was imprisoned and forever suppressed by the torment of corruption. This was too painful.

"If I'm not mistaken, this great formation should imprison the power of numerous souls, like a spiritual reserve."

"Spirit Supply Depot?"

This truly entered a blind spot in Li Muyun's knowledge, prompting him to ask a question.

While chatting with Li Muyun, Rabbit God did not stop observing the array at all.

"It is the soul reserve. When the immortal race was established, regardless of whether they were righteous or evil, they all had this reserve, which was probably similar to a spirit stone."

Upon hearing this, Li Muyun was startled.

This was the first time he had ever heard of the term "Spirit Storage," and he never imagined it could be a place to store and imprison souls.

It sounds somewhat similar to the Ten Thousand Souls Banner.

"Alright, although this formation is of a very high grade, the formation master who set it up was undoubtedly a half-baked one. It's a wonder that I had to search for such an obvious flaw."

In just a few breaths, Rabbit God found the key point of the formation and spoke repeatedly.

"Pay attention to the red-clad skeleton in the southeast corner. The key to the formation is on the top of his head. But be careful when you go over there. Follow the Qian three lines and the Kun six turns. Don't take a wrong step, or you will activate this great formation and cause an anomaly."

After saying that, Rabbit God took a deep breath and conjured up the Six Souls Divine Banner Sword out of thin air.

The short sword was pitch black, with a triangular tail and six banner tails fluttering gently. It was surrounded by incredibly mysterious creation patterns, like a soul-connecting shore between the human world and hell.

"Hold this sword, and with the power of my soul, I can suppress the operation of this formation for a moment. Remember, do not go the wrong way!"

Li Muyun took the Six Souls Divine Banner Sword from his hands and nodded repeatedly. If even Rabbit Lord treated it with such care, he would naturally not be careless.

"Brother Zhao, I have a solution. Wait here for me, do not rush into the formation. I will go and break it."

After giving Zhao Tianming a few instructions, Li Muyun held his breath and focused intently. Holding the Six Souls Divine Banner Sword, he followed the directions given by the Rabbit God and made his way step by step toward the red-clad skeleton in the southeast corner.

However, as soon as Li Muyun stepped into the formation, an overwhelming surge of soul power rushed towards him, threatening to shatter his consciousness in an instant.

"Water transforms into fire, thunder transforms into wind, the sword of the soul!"

As the Rabbit God chanted the incantation, the Six Souls Divine Banner Sword suddenly unleashed astonishing soul power, instantly freezing the great formation and causing the soul power to freeze.

"Now! Get into position! The key to the formation is right on top of that red-clad skull!"

Li Muyun quickly dodged, taking each step carefully and precisely placing himself in the spot indicated by the Rabbit God, finally reaching the red-clad skeleton.

The red-clad skeleton sensed the aura of the newcomer and began to struggle violently, emitting mournful cries. However, it was bound by chains and firmly tied to the Yang God Pillar, unable to escape.

"excuse me!"

Li Muyun shouted loudly, and then the Six Souls Divine Banner Sword suddenly stabbed towards the top of the red-clothed skull's head.

hum!

The sound of metal clashing against stone rang out as the Six Souls Divine Banner Sword penetrated deep into the red-clad skeleton's spirit.

The cave began to tremble violently, and the blood on the Yang God Pillar faded at a visible speed.

The skeletons turned to ashes, and the azure spiritual energy broke free from its restraints, condensing into a dazzling galaxy in the dome, instantly opening the gate.

A crack appeared at the center of the vortex, and countless soul forces scattered out as if trying to escape.

The Buddha-Demon Heart in Li Muyun's arms suddenly pounded violently, and the old monk licked his lips. He had long sensed this enormous soul power and was already impatient.

Zhao Tianming, who was standing beside him, also realized what was happening from the beginning and quickly used his methods to imprison the power of the soul.

Under Li Muyun's Buddha-Demon Heart and the old monk's purification, a large amount of soul power was transformed into pure spiritual energy. According to their previous agreement, this treasure was to be divided equally between the two of them.

Under the nourishment of countless pure soul powers, Li Muyun was able to break through to the third stage of the Nascent Soul realm, and Zhao Tianming also benefited from this blessing and entered the third stage of the Nascent Soul realm.
