Gu Xuan became serious and wiped away the bloodstains.

"Raise the battle!"

With his command.

The sword formation that had been secretly set up earlier was suddenly activated!

Countless sword lights burst forth from the void, weaving together a net that covered millions of miles.

"The Immortal Slaughtering Sword Formation?!"

The Tongtian Sect Leader, watching from afar, frowned. "The Immortal Slaughtering Sword Formation is fine for killing immortals, but can it kill gods?!"

"If it were the previous Immortal Slaughtering Sword Formation, it would indeed be impossible to do so."

Laozi smiled and said, "But Fellow Daoist Gu is using... a modified version of the God-Slaying Sword Formation!"

Within the sword formation, Jie'an let out a painful roar.

His dark armor cracked and crumbled under the sword light, revealing the grotesque flesh writhing inside.

"Gu Xuan!"

Jie'an roared madly, "You think you can kill me like this?"

He ripped open his chest, revealing a pulsating, dark heart: "With the blood of an ancient god, I summon the source of the bizarre!"

"not good!"

Laozi suddenly changed color, "He's going to summon the source of the strange phenomenon!"

A chilling glint flashed in Gu Xuan's eyes: "A strange origin? Kill it without hesitation!"

He held the sword with both hands.

He transformed into a dazzling stream of light, piercing straight into Jie'an's heart!

Where the sword's edge passes, even time seems to stand still.

"Pfft!"

The divine sword pierced through his chest, pinning that dark heart to the void.

Before Jie'an could even unleash its strange power, its eyes widened in disbelief as it stared at the sword hilt before its chest: "No... this is impossible..."

"Destroy."

Gu Xuan uttered a single word.

"boom!"

A dazzling white light erupted from Jie'an's body, and his body cracked inch by inch like shattered porcelain.

Finally, amidst a series of mournful cries.

This eerie Heavenly King, who was at the peak of the Ancient God Realm, was completely annihilated!

......

At the moment Jie'an died.

A deathly silence enveloped the Primordial Immortal Realm!

After a long silence, the Primordial Celestial Venerable sighed, "The younger generation is truly formidable!"

The Grand Master of Heaven's expression was complex: "Godslaying!"

"I thought my talent was amazing enough, but compared to Fellow Daoist Gu, it's nothing but trash!"

The Medicine Buddha clasped his hands together and said, "Amitabha! The Xuanhuang Universe, and indeed the entire Star River Domain, is about to undergo a great change."

Laozi, however, turned and went back to his palace with a smile: "Interesting, very interesting."
