"Not good!" Jiang Ziya's complexion dramatically changed, urgently ordering the alarm to be sounded, and in an instant, Chaoge City went into strict alert.

At the same time, warriors like Li Jing and other military leaders also sensed the anomaly, they quickly donned their armor and grabbed their spears, and hastened towards the outside of the city. When they arrived in front of the formation, all they could see was the black mist filling the sky; the Slaying Immortal Sword Formation had already taken shape, with terrifying Evil Qi so substantial it made people shiver without feeling cold.

"This, this is the Slaying Immortal Sword Formation!" Li Jing's voice trembled a bit as he stared intently at the black mist filling the sky, his heart filled with utter shock.

Jiang Ziya's face had turned even paler; he knew that with this Great Formation barring the way, there was no longer any possibility for the army to pass, which was undoubtedly a huge blow to the Xi Qi army.

While everyone was in a state of shocked indecision, Guang Chengzi, Chi Jingzi, and a group of Chan Sect Golden Immortals arrived riding clouds, their faces all showing grave expressions. Guang Chengzi looked at the Sword Array in front of him and said in a deep voice, "This formation is no small matter; only the Sect Hierarch himself can resolve it."

Hearing this, Jiang Ziya felt a surge of joy in his heart and quickly ordered people to set up a reed tent, burn incense, and pray, demonstrating respect and anticipation for Yuanshi Tianzun.

Before long, the reed tent was set up, and Jiang Ziya himself burned incense and prayed in front of the tent, his voice sincere and respectful: "Master above, your disciple Jiang Ziya humbly invites you to descend and help our Xi Qi army break this formation."

As Jiang Ziya prayed, the clouds in the sky churned, and divine beams of light descended from the horizon, and everyone felt an intangible pressure making it hard to raise their heads.

Moments later, a solemn voice echoed through Yun Xiao: "No need to panic, everyone, I have arrived."

As soon as these words fell, they saw a middle-aged Daoist wearing a long robe and large sleeves descending slowly on the Nine Dragon Incense Sedan – it was none other than Yuanshi Tianzun. His gaze, deep as an abyss, fell upon the Slaying Immortal Sword Formation, revealing a hint of inquiry.

Upon seeing Yuanshi Tianzun personally arriving, Jiang Ziya was overjoyed, immediately kneeling to the ground, showing utmost respect: "Disciple Jiang Ziya, welcomes the grand arrival of the Master."

Yuanshi Tianzun nodded his head, signaling Jiang Ziya to get up. His gaze once again settled on the Slaying Immortal Sword Formation, his hand seal changed, and an invisible strength began to gather around him.

The Evil Qi within the Slaying Immortal Sword Formation seemed to sense a threat, starting to roil restlessly, with the power of the Sword Array continuously consolidating, as if preparing for the imminent confrontation.

Tongtian Sect Hierarch, riding the Kui Niu, dashed through the clouds like a streak of black lightning, reaching the space above the Slaying Immortal Sword Formation in the blink of an eye. He looked down at Yuanshi Tianzun from a high vantage, his eyes filled with disdain and provocation: "Yuanshi, do you think you alone can break my Slaying Immortal Sword Formation?"

Yuanshi Tianzun looked up at Tongtian Sect Hierarch, a faint smile appearing on his face, as if he had long anticipated everything before him. He spoke calmly and firmly, "Tongtian, you are mistaken. We are here to break the formation, not to fight alone."

Before his voice had faded away, the sound of a cow mooing cut through the dark clouds, and Taiching Saint was seen descending slowly on a blue ox from the sky, landing beside Yuanshi Tianzun. The blue ox's eyes flickered with profound light, and the Taiching Saint's demeanor was composed, as if all worldly strife were unrelated to him.

Seeing this, Tongtian Sect Hierarch's heart was a mix of shock and rage, his gaze becoming as sharp as a knife, as if he wanted to slice through everything before him. His voice emitted uncontrollable anger, "Eldest Brother, we are both among The Three Pure Ones, why do you always side with Yuanshi?"

Taiching Saint looked at Tongtian Sect Hierarch, his expression as unmoving as a mountain, his voice carrying an unfathomable calmness: "Third brother, Shang's fall and Zhou's rise is the will of Heavenly Dao; you Jie Sect hold yourselves in too high esteem, wishing to defy the heavens, I naturally cannot overlook it."

Tongtian Sect Hierarch's body shook slightly with rage, the flames in his eyes seeming to set the sky ablaze with a crimson hue. His heart was filled with reluctance and resentment, but he knew that now was not the time to argue with his elder brother.

Tongtian Sect Hierarch stared at the three Saints before him, his voice tinged with mockery: "The Slaying Immortal Sword Formation is the foremost offensive formation under Heavenly Dao; it cannot be broken unless the four Saints gather together. Even if both of you were to act together, do not dream of breaking my formation."

Yuanshi Tianzun smiled faintly as if already having anticipated this. He looked calmly into the distance and then heard harmonious and pleasant Buddhist chants from the sky, followed by the seven-colored Auspicious Cloud slowly drifting from the Western Horizon, upon which stood Introduction and Zhunti, the two Sect Hierarch Saints. Their arrival made the already tense atmosphere seem even more solemn and dignified.

Tongtian Sect Hierarch's face became extremely ugly, his anger burning in his eyes, unbelieving that the four Saints present could really work together to break the Slaying Immortal Sword Formation.

The voice of Introduction Saint was like a Buddhist chant, echoing in everyone's ears: "Tongtian, the Slaying Immortal Sword Formation is strong, but not unbreakable. Today, with the four Saints gathered together, we will surely find a way to break it."

Zhunti Saint looked solemn, staring at Tongtian Sect Hierarch and said in a heavy tone: "My brother Introduction and I have come to break the formation at the invitation of our brother Yuanshi, I implore you Tongtian to not take offense."

"Fine... fine! Fine!" Tongtian Sect Hierarch let out a cold laugh, hands clasped behind his back, his gaze like lightning as he swept across the four Saints: "Even if all four of you Saints gather together, I want to see for myself just how you will break my Slaying Immortal Sword Formation. If today you fail to break the formation, do not blame me, Tongtian, for being ruthless!"

The four Saints did not speak further, their gazes meeting as if they had reached some tacit understanding without words. Yuanshi Tianzun was the first to step towards the Sword Array, followed closely by Introduction and Zhunti, with Taiching Saint slowly following behind.
