The ancient return was exposed by his sister's live stream.

More than ten thousand years.

The scrolling speed of the comments in the live stream has slowed down, not because no one is sending them, but because everyone is watching the screen.

Those four sword marks that pierced through the star's core were too shocking to look at.

Several seconds passed before the comments section came back to life.

"Who is fighting here...?"

"They actually set up such a massive formation..."

"Are the large red spots remnants of a great war between ancient cultivation civilizations?"

"The traces of a battle, still there after ten thousand years?"

"Those red clouds—are they all sword intent compressed to its extreme?"

"This...is terrifying..."

Yang Wanqing's lips were trembling. Not because of the cold.

She was a cultivator at the Golden Body Realm, and she knew what sword intent was.

But she couldn't imagine what kind of sword could cleave the space between planets.

What kind of battle could leave a scar on a planet larger than the Earth itself?

Moreover, it will never heal.

Chen Siyao clenched her fists.

She looked at the surging, bloodthirsty sword intent outside the protective barrier. Each strand was wandering aimlessly.

There was no direction, no goal. But the killing intent remained.

It's been ten thousand years.

The person who created these sword intents has long since disappeared. They may be dead. They may have gone to another star system.

But the sword intent still lives on.

The murderous intent still lives on.

Chen Siyao knew this was not an easy battle.

This is...

A formation.

The Bloodthirsty Sword Intent was not a byproduct of the battle. It was deliberately compressed and sealed within this area.

Those four sword marks were not random attack marks; their positions, angles, and spacing constituted a certain geometric relationship.

An ancient killing formation compressed to its extreme.

The formation is powered by the bloodthirsty sword intent that has never dissipated.

No repairs were made.

This fact is more unsettling than the sword scar itself.

Chen Siyao stared at the four rifts that pierced her vision, her mind quickly flipping through the records she had seen in the Golden Cloud Sect's classic texts.

The spatial rift has an extremely strong self-healing ability, even if it is a rift torn open by a full-force attack from a powerful expert in the Divine Realm.

It usually closes naturally within a century.

But these four cracks have existed for countless millennia.

It's still brand new.

"Keep going." Chen Hao's voice came from ahead.

The spiritual energy shield carried the three through the gap between the four sword marks and sank deeper into the depths.

The concentration of the Blood Fiend Sword Intent had reached an absurd level; the space outside the protective shield was almost entirely dyed a dark red, preventing even light from penetrating.

Yang Wanqing pressed her face against the inner wall of the protective shield and looked out. She couldn't see anything clearly. Everything was red.

"Master, how much deeper down there is...?"

Chen Hao did not answer.

They walked down for about half a cup of tea's time. The red color began to change.

It's no longer a pure dark red; a silvery-gray sheen shines through from below, diluting the red base somewhat.

The temperature is also changing.

Extremely hot.

A thin layer of sweat appeared on Yang Wanqing's forehead. She glanced at Chen Siyao, whose temples were also covered in beads of sweat.

"This is……"

"Liquid metallic hydrogen," Chen Siyao said.

The base of the Great Red Spot. Near Jupiter's core. Scientists speculate that something exists inside Jupiter: an ocean of liquid metallic hydrogen.

Right now, right beneath their feet.

The silvery-gray "sea" finally came into view. It was no ordinary ocean.

Liquid metallic hydrogen forms a fluid under extremely high pressure, with a metallic luster on its surface, and each fluctuation refracts strange silver light patterns.

And right above that silvery sea...

A stone slab is suspended in mid-air.

Yang Wanqing was the first to see it. "What's that?"

The stone slab wasn't large, about the size of a table. It was entirely black, with chipped edges, as if it were a piece broken off from something much larger.

But what caught the three people's attention was not the stone slab itself.

It's something on the stone slab.

Even from a distance of several miles, Chen Siyao could sense the aura emanating from the stone slab. Two kinds. One was the Dao.

The vast and immeasurable Dao intent caused her divine sense to tremble the moment it came into contact with the afterglow.

The other is the sword, which shares the same origin as the surrounding bloodthirsty sword intent, but is more refined and purer.

That's the source.

The bloodthirsty sword intent that permeates the entire large red patch originates from this stone slab.

"Brother." Chen Siyao's throat was a little dry. "Can I come closer and take a look? There seem to be words on it."

Chen Hao nodded.

The protective shield moved forward.

Ten li. Five li. Three li. One li.

The contents on the stone slab became clearer and clearer.

Array patterns. Dense array patterns covered the entire surface of the stone slab, but they were unlike any array patterns Chen Siyao had ever seen in the Tianji Array Sect.

Those lines weren't carved on; they grew naturally into the stone.

There are three characters between the array patterns.

Seal script. Dark gold color. The strokes are vigorous and powerful, penetrating deep into the stone.

"The Immortal Slaughtering Formation".

Chen Siyao slowly read out these ancient characters, and a chill ran down her spine.

She stood still. Yang Wanqing also saw those three words clearly, and remained silent for a long time.

The live stream chat stopped the moment those three words appeared.

It's not that the system is lagging. It's that everyone forgot to type.

Three seconds later, the comments reappeared, but much slower than before. Each one carried a tone of disbelief.

"The...Immortal Slaying Formation?"

"Am I seeing things?"

"Wait... wait, wait... The Immortal Slaughtering Formation... The Immortal Slaughtering Formation of the Tongtian Sect Master?"

"The ancient war of immortal cultivation. The Intercepting Sect's faction. That Immortal Slaughtering Formation?!"

"So, the large red spot..."

"The Great Red Spot is the battlefield remnant of the Immortal Slaughtering Formation?!"

Yang Wanqing came to her senses and lowered her voice, as if afraid of disturbing something.

"Yao Yao".

"Um."

"The Master of the Heavens. The Celestial Venerable of the Spiritual Treasure. One of the ancient Celestial Venerables."

"Um."

Yang Wanqing swallowed hard. "That level of fighting... the mark left... is this big red spot?"

Chen Siyao didn't answer her. She turned to look at Chen Hao.

"Brother. Is this the legendary Immortal Slaughtering Formation of the Celestial Venerable Lingbao?"

Chen Hao looked at the array plate stone and nodded calmly.

It was quiet for a long time.

Yang Wanqing's mind was racing. The Great Red Spot—over 13,000 kilometers in diameter.

It's bigger than Earth; this huge area is the remnant of a battle.

The bloodthirsty sword intent has lingered for millennia and has yet to dissipate. The four sword marks that cleaved through space have not yet healed.

Heavenly Venerable.

The pinnacle of ancient cultivation civilization.

She had seen the term "Celestial Venerable" in historical documents and classic texts before. She knew it was very powerful. But what exactly did "very powerful" mean...? She had no point of reference.

There is now.

The reference points are right beneath your feet, very clear, all around you, in this red storm that's bigger than the blue planet.

An array set up by a Celestial Venerable, the remnants of a battle, after countless millennia... can still cover the area of ​​two blue planets.

Someone in the live chat did the math.

Scientists say the Great Red Spot is shrinking. It's shrinking by about 930 kilometers per year. Following this rate backwards...

"The ancient war of cultivation dates back at least ten thousand years. How big would this large red spot have been ten thousand years ago?"

"The reason why it's called the Immortal Slaughtering Formation now has a clear explanation."

"Based on 930 kilometers per year..."
