Primordial Era: I am a gourd vine, starting with seven gourds combined into one.

Of course, the Four Swords of Zhuxian and the Zhuxian Formation Diagram, which were forged later, are still the Four Swords of Zhuxian and the Zhuxian Formation Diagram.

Its power is roughly the same as the original.

At this moment, Lin Yang summoned the Four Immortal-Slaying Swords and the Immortal-Slaying Formation Diagram to set up the Immortal-Slaying Sword Formation, which would encompass the entire Blood Sea within the formation.

In this way, Lin Yang can find the River Styx in the Sea of ​​Blood.

The methods for finding people and treasures vary depending on the location and the individual. Lin Yang found Wanshou Mountain and Zhen Yuanzi by relying on Ziwei Doushu (a form of Chinese astrology) and the spiritual roots of the Fusang and Yuegui trees, which were mysteriously connected to the fortune of the Ginseng Fruit Tree. This combination led him to find Zhen Yuanzi.

But now, he's using a different method to find the Styx River in the Netherworld Blood Sea.

Through this Immortal Slaughtering Sword Formation, the Styx River in the Sea of ​​Blood is forced to reveal its weakness. At the same time, since the Four Immortal Slaughtering Swords, the Yuan Tu Sword, and the Abi Sword are all killing swords, there will be a mutual attraction of their energy.

It can be said that, with a plan in mind and a plan in reality, Lin Yang was basically able to find the River Styx using this method without any problems.

However, since the Immortal Slaughtering Sword Formation has never appeared in the prehistoric world, Lin Yang also needs to be careful about the impact and avoid revealing that he possesses the Immortal Slaughtering Sword Formation.

Otherwise, before Hongjun could even deal with him, the Demon Ancestor Rahu would come looking for trouble.

After all, Luo Hou had been working hard for so many eons underground in Mount Sumeru, and the authentic Zhuxian Four Swords and Zhuxian Formation Diagram he forged had not yet been revealed.

Instead, Lin Yang's pirated version of the Immortal Slaughtering Sword Formation appeared first. How can this be explained?

Fortunately, this Netherworld Blood Sea was originally a desolate place for living beings.

When Lin Yang unleashed his magic weapons, he first scanned the sea of ​​blood with his divine sense to confirm that no other living beings were present before unleashing the Four Swords of Zhuxian and the Zhuxian Formation Diagram.

The Immortal Slaughtering Formation Diagram flew out and suddenly plummeted into the sea of ​​blood, disappearing without a trace.

A moment later, countless array patterns appeared in the boundless sea of ​​blood. With a loud boom, a portal rose up in the due east direction. The Immortal Execution Sword transformed into a beam of light and shot into the portal, hanging upside down on it.

This is the Zhuxian Gate, one of the four gates of the Zhuxian Sword Formation.

Then, the Immortal-Trapping Gate rose up to the due south, and the Immortal-Trapping Sword was hung on it.

The Immortal Slaughtering Gate rose up in the due west direction, and the Immortal Slaughtering Sword was hung on it.

Finally, the Immortal Gate rose up to the due north, and the Immortal Sword was hung on it.

The four swords and one diagram finally formed a massive, deadly formation.

Originally, once this great formation was completed, it would have been extremely terrifying, and if its aura were to leak out, it would have caused an earth-shattering upheaval.

But Lin Yang did not seek attention; instead, he concealed all of this.

But no strange phenomena were visible outside the formation, while inside the formation, it was terrifying.

The four swords hanging above the four gates trembled simultaneously, and instantly, endless sword energy was generated, dense and numerous, spreading throughout the void and every part of the sea of ​​blood.

The terrifying killing intent stirred up the entire sea of ​​blood, causing it to churn and roar with rolling waves of blood, creating a truly spectacular sight.

However, to Lin Yang's surprise, the first thing to be forced out by the Immortal Slaughtering Sword Formation was not the Twelfth Grade Karmic Fire Red Lotus, nor the Styx River, the Yuan Tu Sword, or the Avici Sword.

Instead, there was a fist-sized insect egg and a small, jet-black flag.

The small, jet-black flag, seemingly a companion treasure of the insect eggs, automatically protected its owner upon encountering the surging killing intent and sword energy, unfurling with a whoosh.

Instantly, it gathered an endless sea of ​​blood water, like a tornado, tightly enveloping the insect egg, and then it was about to take the insect egg and break through the void to escape.

But this is the internal array space of the Immortal Slaughtering Sword Formation, and it's not so easy to break through.

Not to mention that the flag is now completely unpowered as no one is urging it on.

Despite several collisions, the void remained unbroken.

There was no other way but to protect the insect eggs with all their might and preserve themselves within the Immortal Slaughtering Sword Formation.

Lin Yang's eyes lit up as soon as he saw the flag, and he thought to himself, "I've searched high and low without finding it, but it's right here in the blink of an eye."

It turned out that the flag was the Northern Flag, the Xuan Yuan Water Control Flag, one of the Five Primordial Flags.

Although there are legends that the flag is in the Sea of ​​Blood, and some even say it is a companion treasure of the River Styx.

But now it seems that it was half right and half wrong.

The flag was indeed in the sea of ​​blood, but it was not a treasure associated with the River Styx; rather, it belonged to the Mosquito Taoist.

Indeed, Lin Yang recognized it too. The insect egg protected by the Xuan Yuan Water Control Flag was a mosquito egg, and what was being bred inside was none other than the Mosquito Daoist.

This Mosquito Taoist also had an extraordinary background, no less than that of the Styx River. He was called the Primordial Beast, Bloodwing Black Mosquito.

Although Lin Yang didn't know why it was called a ferocious beast, given Mosquito Taoist's abilities, the word "fierce" was indeed fitting.

Mosquito Taoist's first appearance was during the Investiture of the Gods. At that time, he was captured by the Western Sage, the Guide Taoist, for some unknown reason, and was put into a bundle by the Guide Taoist.

During the great calamity, the two Western Saints were invited by the Primordial Heavenly Lord to break the Ten Thousand Immortals Formation set up by the Tongtian Sect Master.

However, the Guide Daoist was careless and forgot about the existence of the Mosquito Daoist. He still used the bundle to take in the Turtle Spirit Holy Mother, the direct disciple of the Tongtian Sect Master.

Taking advantage of the opportunity, Mosquito Taoist devoured all of the flesh and blood of the Holy Mother Turtle Spirit in the bundle, not even sparing her true spirit. Afterward, he escaped from the bundle and flew directly into the Pure Land of Ultimate Bliss, where he also devoured three of the twelve tiers of the Western Sect's treasured spiritual treasure, the Golden Lotus of Merit.

The Mosquito Taoist, who committed this major crime, can indeed be described as extremely vicious.

After all, the Twelve-Petaled Golden Lotus of Merit is extremely precious. It is the most valuable spiritual treasure of the two Western Saints and is used to suppress the fortune of major sects. Yet he dared to eat it. Putting everything else aside, his ruthlessness is something that no powerful being can match.

Of course, the main credit goes to his mouth, which is really quite powerful. He can even bite through a top-grade innate spiritual treasure like the Twelfth Grade Merit Golden Lotus. No wonder even saints have fallen for his trick.

This is similar to how, during the same Investiture of the Gods, Kong Xuan's five-colored divine light could be swept into the hands of a sage due to carelessness.

Lin Yang has mastered the Five-Colored Divine Light, but this mouth is actually on the body of Mosquito Daoist. Moreover, Mosquito Daoist has not yet been born and is still just an insect egg.

After a moment's thought, Lin Yang took action and put away the Xuan Yuan Water Control Flag.

The Twelfth Grade Karmic Fire Lotus is still nowhere to be seen, but the Profound Origin Water Control Flag has already been acquired.

In addition to the Flame Light Banner that Lin Yang already possessed, and the Plain Cloud Banner that he had in Wang Shu, three of the Five Innate Banners had ended up on Lin Yang's side.

"Who knows, in the future, it might actually be possible to gather all five flags and set up the Five Elements Formation?" A thought flashed through Lin Yang's mind, and then he looked at the insect egg with a more cautious expression.

Having seen the example of the Sage who guided the sage, he naturally wouldn't be careless. Now, he didn't know what to do with the insect eggs. He needed to collect them, but it certainly wouldn't be a simple matter of collecting them.

Otherwise, if these insect eggs hatch and eat one of his precious items, Lin Yang would feel heartbroken.

Then, Lin Yang used his magic to cast sealing runes that fell into the insect eggs.

It seeped in, and at the same time, a large amount of blood also rushed in and was sealed away.

After a while, it turned into a large, dark, blood-red cocoon.

A faint, subtle life force could be detected emanating from within.

However, Mosquito Taoist had been sealed away by Lin Yang, who had also placed numerous restrictions on him.

If the insect eggs hatch and the Mosquito Taoist is born, Lin Yang will know immediately and will not worry about him causing trouble.

Only then did Lin Yang put away the insect eggs and breathe a sigh of relief. He then continued to activate the Immortal Slaughtering Sword Formation to thoroughly attack the Netherworld Blood Sea.

"Ugh!"

Finally, accompanied by a sigh, a divine sense transmitted a message: "Brother Dao, please stop. Styx has submitted!"

The one transmitting this divine sense was none other than the Styx Ancestor, who had concealed his aura and was hiding somewhere in the Blood Sea.

Or rather, Styx Daoist. The current Styx is not qualified to call himself an ancestor in front of Lin Yang.

It would be more appropriate for him to call Lin Yang "Ancestor".

Styx's telepathic message immediately revealed his location, and Lin Yang's gaze swept over him.

"boom!"

The pressure of the Immortal Slaughtering Sword Formation also surged over, and a series of creaking and groaning sounds that made one's teeth ache were heard. Then, a large formation emerged, unable to bear the weight any longer.

This formation is truly remarkable; it managed to conceal so many things even after the Immortal Slaughtering Sword Formation swept away its power.

This grand formation is called the Netherworld Blood Sea Grand Formation. As the name suggests, this grand formation is integrated with the entire blood sea and has a very comprehensive function. It can defend, attack, and hide.

The Styx River used this great formation to conceal itself, and was nurtured within it, making it perfectly safe.

Even the other powerful figure in the Netherworld, the Xuan Yin Ancestor, had visited this Blood Sea countless times and had searched everywhere within it for treasures.

Yet they remained unaware of the existence of the River Styx.

Styx had always believed that it would continue to be conceived and born safely and peacefully.

But Styx never expected that, amidst natural disasters and man-made calamities, Lin Yang would directly deploy a fierce and menacing array to cover the entire sea of ​​blood in search of him.

The methods used were so excessive that it goes without saying. At least, even the Xuan Yin Ancestor didn't do that.

But it must be said that the effect was really good, and Styx had no choice but to admit defeat.

He had no choice. First of all, he hadn't been born yet, so he had no cultivation at all, and naturally, he didn't have any magic power to activate his innate treasure.

Secondly, the four swords Lin Yang used exerted an extremely strong pull on the Yuan Tu Sword and the A Bi Sword.

Even though he tried to soothe her with his divine sense, he had reached his limit.

All these factors combined left him with no choice but to reveal his location to Lin Yang.

Now, the Styx can only take things one step at a time.

"What a magnificent formation." Lin Yang did not forcefully break the Netherworld Blood Sea Formation, but after examining it for a while, he stopped the Immortal Slaughtering Sword Formation.

Then, with a swift movement, he entered the great formation directly.

From the outside, this Netherworld Blood Sea Formation looks like a large blood cocoon, or like a heart, thumping and beating.

Inside, however, was a blood-soaked wasteland, forming a completely different world.

However, the world was dark and the light was dim, but there was one place that was very bright, with clusters of firelight illuminating the surroundings.

The place where the firelight was was where the River Styx was located. Lin Yang looked over and saw a huge lotus flower growing there.

The lotus flower has twelve petals, and a scarlet flame burns continuously on it.

This is precisely the Twelve-Petaled Karmic Fire Red Lotus, Lin Yang's target for this trip! And the flames burning on the Twelve-Petaled Karmic Fire Red Lotus are the karmic fire.
