This is because as long as the bodies of the thirty-six flying swords hidden in the core of the sword formation are not damaged, even if these sword threads are broken by attacks, they can still continue to regenerate and remain stable.

It is enough to cope with various challenges, which is the most frightening part of the Da Geng Sword Formation.

However, surprisingly, these mysterious beads do not contain any unexpected elements or techniques.

After they burst, they released thick and bright red smoke, which rose into the sky like rolling dark clouds in an instant.

Once this smoke is released, it immediately spreads to the surroundings, as fast as the wind.

At the same time, it exudes a disgusting, weird smell, the smell is so strong that people stay away from it.

These mysterious round beads are called "Blood Thunder Seeds". According to rumors, they are made from the most filthy and dirty substances in the world.

For the enemy, as long as the treasure is not refined through the magic secret technique, once it is eroded by the blood mist, its power will be greatly reduced, and it may even lose its original spirituality.

No matter how powerful your magic weapon is, or how outstanding your spirituality is, if you want to revive it, you must use the infant fire to carefully refine it for several days again.

However, these blood thunder seeds are extremely rare in the Demon Sect. Not only are the raw materials extremely scarce, but the probability of successful refining is also extremely small, far lower than ordinary thunder beads.

These dozen or so blood thunder seeds are all the accumulation of the young man in the black robe over the past hundred years.

As the elder of one of the ten great demon sects in Jin State, this young man in black robe has extensive knowledge and rich experience.

When he recognized the sword formation set up by Chen Yun at a glance, he immediately thought of using the blood thunder to contaminate Chen Yun's flying sword.

The sword formation needs to be seamlessly connected to exert its maximum power.

If any flying sword malfunctions during the formation, the entire sword formation will collapse instantly.

This strategy is one of the most commonly used methods by the Jin State's magic cultivators to fight against those sword-cultivating sects that are good at controlling sword formations.

However, an extremely rare item like the Blood Thunder Seed is usually not suitable for single combat situations.

It is often only used in large-scale battles.

After all, under normal circumstances, a sword formation cannot be controlled by one person.

Facing the blood mist, although Chen Yun didn't understand why, he also felt the weirdness in it, and couldn't help but feel doubtful. At this moment, a low thunder suddenly sounded.

Flakes of golden light also appeared in the blood mist, and then brilliant light golden lightning shot out like arrows.

As soon as the lightning came into contact with the blood mist, it quickly and violently burned and swallowed everything up.

In a flash, the dozen or so blood mists were destroyed along with Chen Yun's evil-repelling divine thunder.

Chen Yun was shocked.

The evil-repelling divine thunder did not wait for him to activate it, but actually shot out from the flying sword on its own. This was the first time he had encountered this in his cultivation career.

And it was unbelievable that the blood mist, which was obviously an evil thing, could actually resist the evil-repelling divine thunder.

Chen Yun was naturally unaware of this. The properties of these blood thunder seeds, which were specifically designed to defile the treasures of the righteous path, were almost the same as the characteristics of the evil-repelling divine thunders, which were specifically designed to restrain the magic techniques. The two were mutually reinforcing and counteracting.

Under normal circumstances, neither side can defeat the other.

Although the blood mist was numerous, it was still far inferior to the divine thunder contained in the thirty-six flying swords. Therefore, the blood mist was completely cleared away in an instant.

"The Divine Thunder that can ward off evil, these flying swords are all magical weapons made of golden thunder bamboo! How is this possible? How can there be so many golden thunder bamboos?"

Seeing this, the young man in the black robe suddenly changed his expression and screamed.

"I will tell you the answer to this question when you go to hell!" Chen Yun responded bluntly, taking a deep breath and urging his mind again.

Due to the appearance of blood mist, the golden thread that had been suspended quietly gathered towards the center again.

Although this Da Geng Sword Formation is extremely powerful, it still seems a little overwhelmed for Chen Yun today.

Although he was able to drive this sword formation, the speed at which his mana was depleted was alarming. What was worse was that once the sword formation was activated, he would not be able to continue accelerating and thus would not be able to exert the full power of the sword formation.

If not, it would only take an instant for the sword threads to converge at the center and the opponent could be razed to the ground. Why would he allow the young man in black to take other countermeasures to fight against him?

Chen Yun estimated that according to the amount of mana consumption required for the sword formation, in fact only cultivators who had reached the middle stage of the Nascent Soul stage would be most suitable to practice this kind of magical power.

If he had not only mobilized half of the sword formation and his magic power far exceeded that of an ordinary early Nascent Soul cultivator, he would not be able to control this sword formation at all with his current realm.

"Humph! You actually want to use this sword formation to restrain me. Even if your sword formation is unstoppable, can you really cut off the treasure of this sect?"

Hearing this, the black-robed young man's face suddenly turned dark, and he said in a sinister tone. He turned his head and glanced at the golden thread in front of him, which was only more than ten feet away from him. He raised his hand without hesitation and punched himself in the chest with all his strength.

With a "puff" sound, a mouthful of thick black blood gushed out immediately, mixed with a small emerald green flag about two inches in size.

As soon as the banner was spit out, it shone with green light and quickly swallowed up all the black blood around it, and the banner turned into emerald green.

The young man in black robe waved at the banner with a gloomy face. With a "whoosh", the small banner turned into a black light and flew into his hand. Then he rubbed his hands together, and the light became brighter. The green banner instantly expanded to several feet in size.

The banner was flickering green and covered with dark clouds, making it difficult to see its true appearance.

The only thing was that the banner was missing a corner, as if it had been damaged and had not yet recovered.

Chen Yun's pupils suddenly contracted, and he whispered to himself:

"Ghost Banner!"

Earlier, the leader of Yinluo Sect had said that he would use the sect's treasure, the Guiluo Banner, to fight against the Hehuan old demon. Although the latter did not actually use this magic weapon, Chen Yun had already memorized the name.

Now that the young man in black robe has shown the banner, Chen Yun can naturally guess what it is.

"You have a good eye! This is one of the main banners of the Twelve Demonic Banners. You might as well experience its power for yourself."

Seeing Chen Yun recognize the object in his hand, the black-robed young man was stunned for a moment, then sneered and said, obviously full of confidence in the object in his hand. Then the young man held the banner tightly and gently waved the golden silk thread in a certain direction.

With a "puff" sound, emerald green clouds emerged from the banner, and then rapidly expanded, covering the young man's figure.

The area suddenly became chilly and the wind howled continuously. A large number of dark clouds gathered in the sky at some point, and in an instant the entire sky became overcast, completely blocking out the sunlight.

The sky became dark and dim, and a green ghost fog quietly spread all around, and the sounds of ghosts crying and wolves howling rose and fell one after another.

Just by gently waving the banner in his hand, the world has changed. No wonder this person is so confident in the Guiluo Banner. Even though Chen Yun has a firm belief in the Dageng Sword Formation, he is still shocked at this moment.

Just at this moment, the sound of breaking air came from the opposite side, and countless ink-black thin lines shot out from the mist where the young man was like arrows, and rushed straight towards Chen Yun.

With a flash of golden light, the restriction in the sword formation was activated. Countless golden threads crisscrossed and shone. After all the black lines paused for a moment, they turned into countless tiny fragments and fell to the ground.

However, immediately afterwards, these broken black lines turned into balls of green mist, rushed back, and merged into the green mist again.

"Eh!"

Before Chen Yun could react, the black-robed young man in the green mist sighed in astonishment. These ghost threads were extremely tough, but they were also unable to withstand the attack of the opponent's sword formation. This was beyond his expectations.

After pondering for a moment, Chen Yun decided not to hold back any longer and unleashed the strongest power of the ghost flag in his hand.

He suddenly threw the flag in his hand out from the green mist, accurately inserted it about three feet in front of him, and then stood still.

Then, an obscure spell was heard from the fog, and gusts of cold wind carried the surrounding fog and gathered towards the center from all directions.

The green flag expanded rapidly as it swayed, reaching a height of two meters in an instant. At this moment, the hazy mist on the flag gradually dissipated, revealing its true appearance.

When Chen Yun saw this scene, his expression suddenly changed.

"You actually used so many souls of living beings to refine this flag? How many people were killed?" Chen Yun asked loudly and angrily.

On the emerald green banner, there are countless miniature human faces.

These faces included men, women, young and old, and they seemed to be alive and wriggling on the banner, with each face showing an expression of extreme pain. This scene was truly horrifying.

"Who can know the exact number of people? Perhaps there are hundreds of thousands or even more. And among them, it must include the spirits of hundreds of practitioners to be able to refine this main banner."

The young man's cold reply came from the green mist.

Chen Yun fell silent, staring at the green mist with cold eyes. After a long while, he uttered a few words softly.

"You deserve to die."

"Deserve to die? Countless people have said similar words to me. Yet, I am still alive and well. On the contrary, the souls of those who said these words have long been collected by me into the flag and have become a part of it. You will definitely not be an exception," the young man responded sarcastically.

Then, he seemed not to want to continue the conversation, and a bright red spell hit the huge banner accurately.

The green light became brighter, and suddenly, a huge black hole with a diameter of several feet appeared on the banner. Black gas gushed out, and a howling wind was heard inside the black hole.

The sound of "puff" continued to be heard. Several giant skulls with ghostly fire in their eyes and green smoke spewing out of their mouths flew out from the banners calmly and lined up in a row.

The largest skull had two huge horns on its head, but the facial features below were almost indistinguishable from those of humans.

Could it be that this skull was actually a demon beast in the transformation stage before its death? Chen Yun couldn't help but be shocked.

However, what happened next forced Chen Yun to temporarily put aside his doubts.

In addition to the first few skulls that appeared, all kinds of ghost fire skulls continued to emerge from the black hole on the green banner.

In the blink of an eye, hundreds of them appeared, crowding around the man in black robe.

"Go!" The young man in black robe made a gesture and pointed in the direction of Chen Yun in the green mist.

All the white skulls suddenly jumped out from the curtain, making sharp sounds of breaking through the wind, and spurted out emerald green ghost fire from their mouths, rushing straight towards Chen Yun who was standing opposite.

However, just when these misty ghosts rushed forward several feet, countless dazzling golden lights suddenly appeared in the field, flashing rapidly.

However, this time, things took a subtle turn.

After the golden light passed through the ghost, several extremely thin cracks appeared on all the skulls. However, with a flash of green light, these cracks disappeared without a trace, as if they had never suffered any damage before.

Those ghosts still attacked Chen Yun without hesitation.

Chen Yun was shocked at first when he saw the scene before him, but then he reacted quickly. These ghosts were no longer flesh and blood, they had been refined into strange ghost bodies. Although the sword in his hand was extremely sharp, it could not hurt their invisible bodies, so his attack was obviously ineffective.

However, Chen Yun did not panic. Instead, he immediately launched a more powerful spell.

Just as many ghosts were about to descend, a loud thunder sounded in the air, and a golden net flashing with lightning suddenly appeared in the air, facing the impact of the ghosts head-on.

Chen Yun knew very well that these ghost shadows were transformed from evil spirits, so he activated the evil-repelling divine thunder in his flying sword without hesitation.

However, what Chen Yun did not expect was that when these ghosts saw the golden net appear, although their bodies paused slightly and revealed a hint of fear, at the fierce roar of the leading horned ghost, they all opened their mouths, and the emerald green ghost fire rushed towards the golden net like a shocking rainbow.

Lightning crackled and arcs of electricity jumped on the golden net, successfully destroying a considerable number of will-o'-the-wisp.

However, the downward trend was also blocked, and it was actually resisted by the endless will-o'-the-wisp fire, unable to land.

Chen Yun's heart tightened and an expression of surprise appeared on his face.

If these ghost fires were ordinary evil flames, they would instantly disappear without a trace in front of his evil-repelling divine thunder.

However, although the ghost fires of these skulls still seemed to be suppressed, they were able to barely resist the power of the electric arc, which really surprised Chen Yun.

This Ghost Luo Banner is truly worthy of its name as the Yinluo Sect's treasure.

The black-robed young man standing on the other side saw that the demon in the banner had successfully resisted the evil-repelling divine thunder, and he couldn't help but smile triumphantly, as if he had finally breathed a sigh of relief. (End of this chapter)
