Primordial Era: A man at the mouth of the Guanjiang River marries the Third Holy Mother.

Zhunti Daoist turned to look at Jieyin Daoist, his eyes flashing with surprise and uncertainty.

"Senior brother, what do you think?"

The Taoist priest moved the prayer beads in his hand, and golden light flashed in his cloudy eyes as he made deductions.

After a long while, the Guide Daoist shook his head slightly: "I can't figure it out. The secrets of heaven have been completely cut off. This formation seems to be outside the Three Realms and Five Elements, and is definitely not an ordinary immortal technique."

"This is really interesting."

Zhunti Daoist stroked his chin, a sly glint of excitement in his eyes.

"Yuanshi Tianzun wanted to disturb the Fire Cloud Cave, and our Western Sect also wanted a share of humanity's destiny. We thought we'd have to go through a lot of trouble dealing with Tongtian and Changsheng, but unexpectedly, a Cheng Yaojin appeared out of nowhere and took care of the toughest challenge for us!"

The Taoist priest chanted a Buddhist prayer in a low voice: "Amitabha. Although this formation is strange, it is a great blessing for our Western Great Prosperity."

"With the Three Sovereigns completely trapped and humanity preoccupied with its own survival, the alliance between the Jie Sect and the Shang Dynasty will inevitably crumble. At that time, our Western Sect will be able to spread our teachings eastward without any obstacles."

Just then, a piercing, sharp screech suddenly came from the western horizon.

In that instant, the entire sky of the primordial central region was sliced ​​apart by an extremely pure azure sword intent.

The overwhelming power of the sage was like a celestial river bursting its banks, sweeping across the eight directions and six realms.

Zhunti Daoist suddenly looked up, gazing towards the Central Region, and clapped his hands, laughing loudly: "Haha! Senior brother, look, Tongtian's temper really got the better of him!"

"Chen Changsheng suffered a setback at Huoyun Cave, and Tongtian is going to personally step in to help his grand-disciple regain face."

A hint of anticipation appeared in the eyes of the Guide: "The Sage Tongtian possesses divine swordsmanship and wields the Four Swords of Zhuxian. Let's see if his sword strike can reveal the true nature of that mysterious formation."

Above Mount Sumeru, golden light converged into a giant water curtain, the image firmly fixed on the front of the Fire Cloud Cave.

At this very moment, in the Central Region of the Primordial World, the gazes of countless reclusive powerful beings—from Wanshou Mountain's Wuzhuang Temple, the Netherworld Blood Sea, and Nuwa Palace—all turned toward Huoyun Cave.

Outside the Fire Cloud Cave, a sudden gust of wind arose.

The once peaceful void was suddenly torn apart, and a huge blue chaotic lotus flower appeared out of thin air.

The Tongtian Sect Leader, dressed in a blue Taoist robe, stepped out of the crack with a somber expression, his feet treading on the void.

As the sage descended, the vast sky was instantly filled with azure sword intent.

The spirits of Meishan, including Yuan Hong and the Six-Eared Macaque, who were stationed thousands of miles away on guard duty, were overjoyed to see the arrival of the Tongtian Sect Leader and bowed respectfully from afar.

The Tongtian Sect Leader slightly raised his hand in a gesture, but his gaze remained fixed on the gray light screen directly above the Fire Cloud Cave.

That halo appeared as thin as a cicada's wing, flowing quietly, but in the eyes of the Tongtian Sect Master's sage-like wisdom, it was clearly an absolute barrier woven from ancient rules.

"What a strange seal! Even I can't see through its core array."

The Master of the Heavenly Sect narrowed his eyes and let out a cold snort.

"However, no matter how many mysteries you possess, they are all futile before absolute power!"

With a wave of his right arm, the Tongtian Sect Leader unleashed four divine swords radiating overwhelming ferocity from the void behind him.

The Immortal-Slaying Sword, the ...Trapping Sword, and the Immortal-Slaying Sword!

The four most powerful killing swords since the creation of the world appeared simultaneously, causing the temperature of the entire primordial world to plummet to its lowest point.

The crimson aura and the chilling killing intent intertwined to form a sea of ​​blood, directly staining the sky within a radius of 100,000 miles around Fire Cloud Cave with a dazzling crimson hue.

The void is wailing, the earth is collapsing.

The gray halo surrounding the Fire Cloud Cave seemed to sense this destructive threat as well. The light on its surface suddenly accelerated, and countless ancient and complex black runes emerged from the void, weaving together into a huge mysterious net on the surface of the formation.

"Break for me!"

The Tongtian Sect Leader roared, his right hand forming a sword-like shape as he pointed fiercely at the gray light barrier.

Clang—!

The four Immortal Swords trembled simultaneously, transforming into four million-foot-long sword beams that pierced through the heavens and earth.

The Immortal Slayer brings benefit, the Immortal Slayer brings death, the Immortal Trapper emits red light everywhere, and the Immortal Slayer's transformations are infinitely wondrous!

The four great laws of killing merged completely in mid-air, transforming into an unparalleled killing sword pillar capable of tearing apart the world and reenacting the cycle of earth, water, fire, and wind. With overwhelming force, it slammed into the gray array of Fire Cloud Cave!

This sword strike was truly a saintly strike!

Rumble—!

An indescribable roar exploded in the very center of the primordial land.

The violent energy storm transformed into countless ring-shaped air waves, instantly flattening mountains and rivers within a radius of tens of thousands of miles, and countless fragments of void fell like a torrential rain.

Inside the Jade Void Palace on Kunlun Mountain, the Primordial Celestial Venerable stared intently at the water mirror.

At the Merit Pool of Mount Sumeru, Cundi and Jieyin held their breath.

Inside Biyou Palace, Chen Changsheng, Zhao Gongming, and the others also sensed this earth-shattering attack through communication jade talismans.

Everyone thought that no formation in the world could withstand the power of the Four Immortal Execution Swords, which embodied the killing intent of a saint, for even a moment.

However, what happened the next moment plunged the entire prehistoric world into utter silence.

The moment the devastating sword pillar slammed into the gray light screen, the ancient black runes on the surface of the formation suddenly lit up.

An unprecedented primordial suction force suddenly erupted.

The endless sword energy and killing laws unleashed by the Four Swords of Zhuxian did not cause a violent explosion the moment they came into contact with the light barrier. Instead, they were devoured, decomposed, and assimilated by the gray light barrier as if they had been thrown into the sea!

The light screen only trembled violently three times.

Immediately afterwards, a reverse shockwave burst forth from within the great formation!

when!when!when!when!

Four extremely piercing sounds of metal clashing resounded through the sky.

The four supreme killing swords, Zhuxian, Luxian, Xianxian, and Juexian, were actually sent flying back by the terrifying backlash, turning into four streams of light that tumbled tens of thousands of feet in the void before finally stabilizing themselves!

Above the great formation, the gray halo flowed as before, and the ancient runes slowly disappeared into the void. The entire great formation not only did not suffer any damage, but because it absorbed part of the sword energy of the Tongtian Sect Master's sword, the luster it emitted became even deeper and more solid!

There was a deathly silence in front of the Fire Cloud Cave.

The Tongtian Sect Leader stood in the void, his right hand suspended in mid-air. His face, which had always been arrogant and looked down on all others, showed unprecedented shock.

"How is that possible?!"

The Tongtian Sect Leader was speechless, his tone filled with disbelief.

He personally took action, unleashing the full power of the Four Swords of Zhuxian. Even the Supreme Lord Laozi's Heaven and Earth Xuanhuang Exquisite Pagoda would inevitably be struck, its light dimmed and it shaking violently.

But this formation of unknown origin actually withstood his saintly sword strike and even repelled the Four Swords of Zhuxian.

Kunlun Mountain Yuxu Palace.

pat.

The white jade ruyi in Yuanshi Tianzun's hand slipped and hit the armrest of the sandalwood carriage with a crisp sound.

The Primordial Celestial Venerable suddenly stood up, his eyes wide open, staring intently at the scene in the water mirror, even his breath caught in his throat.
