Looking at the trembling Tianhuang, Cao Ya was stunned for a moment, then his body suddenly trembled, because Tianhuang was emanating a belief: to kill the enemy! It wanted to be stained with blood!

"Alright, so what kind of big shots are they from the upper realm? Let's go see what they're capable of, acting so arrogantly and domineeringly, treating all living beings in the lower realm like ants." Cao Ya laughed loudly, his expression stern yet fearless.

He was mentally prepared when he accepted Tianhuang's offer, especially since he also received the Kunpeng Treasure Technique from Tianhuang.

In a sense, Cao Ya can be considered a successor to the Ten Fierce Female Kunpeng from the late Immortal Ancient Era.

Both Liu Shen and Shi Hao gazed at Tianhuang, understanding why it had moved. It must be because some enemies, who had been etched in their memories for billions of years and were relentless in their fight, had appeared, and were intricately connected to the death of Kunpeng in the past.

"No rush, let's see how things go," Xiaota said, manipulating the ancestral altar to illuminate the desolate region, revealing many terrifying sights.

The location of the Fire Kingdom's capital has long been reduced to ruins. At this moment, nine-colored lightning surges in this place, the sky is shattered, and a giant foot stomps down with difficulty, displaying an arrogant attitude that looks down on all living beings in the wasteland.

However, it must be said that the owner of that foot was indeed terrifying, undoubtedly an extremely powerful being among those who possessed extraordinary abilities. The foot was enormous, wider than the clouds, obscuring the sky, treading upon nine-colored lightning, accompanied by boundless immortal energy and divine laws, its power unparalleled.

"We've come for the Supreme Divine Treasury!" Little Tower said solemnly.

Upon hearing this, Cao Ya and Shi Hao both laughed, and even the usually composed Liu Shen couldn't help but smile.

"The treasures of the Supreme Hall, also known as the Mountain Treasures, have already been obtained by us. We are practicing the Grass Character Sword Technique, the Six Paths Reincarnation Heavenly Art, and so on." Cao Ya rested his chin on his hand and muttered to himself, "Hmm, so the legendary giant tortoise that carries the inheritance of the Supreme Hall and travels through the worlds is actually just a decoy."

"It's not a cover-up, but rather a scheme specifically set up to target some important figure from the upper realm," Little Tower sneered. "Such a grand scheme, I wonder which guy is going to be so unlucky."

"Heh, it would be best if he were dead." Little Tower curled his lip.

Then it manipulated the ancestral altar, and the scene changed again, starting to look at another place, which was the world-famous medicine capital.

Hundreds of miles away from the Medicine Capital, there is a valley where the sounds of Taoism resound, the heavens and earth roar, the divine laws are vast, and the immortal mist surges. A celestial root is glowing, accompanied by the sound of chanting.

"This thing is about to be born..." The little tower trembled, then looked horrified, quite serious.

"What is that?" Shi Hao asked, a thought flashing through his mind.

"That is the first divine root of the upper realm. It is said that it can create supreme beings, create heaven and earth, and coexist with the world. With such a divine object appearing in the world, I wonder what kind of powerful beings it will attract?" Liu Shen sighed.

From then on, the mortal realm was filled with trouble.

Of the group, only Cao Ya's pupils constricted upon seeing the first spiritual root, and then he let out a cold laugh.

"A freelancer?" Shi Hao looked over in surprise, wondering what Cao Ya meant.

"The first spiritual root? Ha, it's just a part of a top-grade immortal medicine. Inside it, there exists an invincible being that can sweep across many universes. Even the great figures of the upper realm are like ants in front of it. To think that you can achieve enlightenment with the first spiritual root is simply wishful thinking and a pipe dream." Cao Ya muttered.

Of the two treasures that have been revealed so far, they have already obtained the Supreme Divine Treasure, but Cao Ya has always avoided the First Spiritual Root like the plague.

Upon hearing Cao Ya's words, Shi Hao and Xiao Ta blinked, seemingly a little bewildered.

Only Liu Shen seemed to ponder for a moment, then her eyes flickered, as if she had been shocked by something.

"That guy who sells fake medicine?" Liu Shen's voice was filled with shock.

“Yes,” Cao Ya sighed. Within the first spiritual root was a part of the body of the one who sold fake medicine. He used this body to travel through various realms, observing the changes in the mortal world, hoping to be moved by something. In the end, he merged multiple fragmented bodies and reversed the situation to attain the realm of Quasi-Immortal Emperor.

That's why this supreme giant among the immortal kings was given the nickname "the one who sells fake medicine".

Because these spiritual roots and divine roots are fucking fake; they're all show and no substance.

"So it was him." Liu Shen murmured, as if suddenly realizing something.

"Liu Shen, who is this 'fake medicine seller'?" Shi Hao asked curiously, rarely seeing Liu Shen's emotions fluctuate so obviously.

"That was an unparalleled powerhouse, an existence that would not perish even if heaven and earth were destroyed," Liu Shen sighed. An unparalleled giant among the Immortal Kings, capable of shattering the universe and collapsing heaven and earth at will, he was simply an unimaginable super powerhouse.

"A top-tier supernatural being from the ancient times?" Little Tower asked, guessing which ancient master would be referred to as "the fake medicine seller".

"No, that's not it. This being is too powerful to mention." Liu Shen changed the subject.

Cao Ya didn't say anything more.

After all, this "fake medicine seller" did it on his own initiative, hiding himself in the great medicine of heaven and earth, witnessing the changes of the mortal world, and tempering his Dao heart.

If you mention it too much, there's no guarantee he won't sense it.

"The first spiritual root actually has such a great secret..." Shi Hao and Xiao Ta were both surprised, their eyes showing strange expressions as they looked at the scene displayed on the screen. If those important figures knew about this, would they be so scared that their legs would go weak?

Outside the Medicine Capital, others, unaware of the inside story, fought to the death for that first spiritual root. The light was dazzling, the world was vast, boundless energy was boiling, many magic arrays were broken, and supreme divine power was being revealed.

"That's... the Ninth Killing Formation!" Little Tower exclaimed.

Seeing Shi Hao's curiosity, Xiao Ta explained:

"The so-called Ninth Killing Formation is the ninth strongest killing formation in the Upper Realm since the beginning of time. It can slay gods and annihilate immortals!"

Shi Hao was moved. Over countless millennia in the Upper Realm, countless arrays must have been created. That array could actually rank ninth, entering the top ten, which shows how terrifying and awe-inspiring it was.

Then Xiaota continued to explain that although this killing formation is said to be the ninth, it is not necessarily weaker than the previous killing formations; it depends on the person using it.

However, the terrifying nature of the Ninth Killing Formation is acknowledged by countless powerful figures over millions of years.

"The Ninth Killing Formation, huh? I'd really like to collect the top ten killing formations from ancient and modern times. If I could comprehend them, I would surely reach the pinnacle of immortality!" Cao Ya pondered.

"Too difficult," Liu Shen said succinctly.

Cao Ya shook his head and sighed. Indeed, one of the top ten killing formations is enough to dominate the universe. If all ten killing formations are complete, even a Celestial King will face calamity.

The problem is that many killing formations have been lost, and no one knows where their lineage is.

He gazed at the scene displayed on the ancestral altar: outside the Medicine Capital, heroes were engaged in a bloody battle, each strike capable of shattering hundreds of thousands of miles of land and even severing stars from beyond the realm, but that vast and unfathomable power was bound by the killing formation.

Some of the powerful individuals perished, severely wounded by their enemies, or killed by the Ninth Killing Array. The vast energy accumulated within their bodies over millions of years erupted, their flesh and blood shattered, and were all devoured by the Ninth Killing Array, disappearing into that land. Then, the first spiritual root at the center glowed, as if it were absorbing endless divine power and essence.

"This scheme is ruthless. It uses the first spiritual root as bait to lure a great figure from the upper realm down, and then uses the ninth killing formation to kill him, sacrificing him to the first spiritual root so that it can regain its highest divinity and be used to help it achieve enlightenment," Liu Shen sighed.

A great figure from the upper realm, whose power oversees vast regions, shines as brightly as the sun and moon, and lives as long as heaven and earth, has become nourishment for the first spiritual root in this place. This contrast is truly astonishing, and one can't help but marvel at the cunning and methods of the person behind the scenes.

"It's all a waste of effort," Cao Ya said, shaking his head. With counterfeiters around, all their schemes are futile. They might not be able to move for millions of years, and after seeing all the world's troubles, even the counterfeiters themselves are starting to feel resentful.

Because in the eyes of the fake medicine seller, these so-called important figures from the upper realm are like ants. Even if he devours millions of them, it will not help his cultivation in the slightest.

On the contrary, the vast world and the mundane world may touch his heart and give him the opportunity to prove himself as a quasi-immortal emperor.

Sure enough, the next moment, Cao Ya saw the First Spiritual Root fly away in the picture, disappearing into the heavens and going to another realm.
