Heaven Slaying Blade

Although he didn't know what had happened, his reaction was unbelievably quick!

Puff!

All of his vital blood was sprayed onto the Black Tortoise shell, and the restless Black Tortoise shell instantly calmed down.

The Supreme Ancient Ancestor let out a sigh of relief at once.

But at the next moment... the arrays around exploded with an endless killing intent. Its power increased directly by a thousand times compared to just now!

The boundless pressure immediately left the Supreme Ancient Ancestor dumbfounded. He never imagined that the arrays here could be so terrifying, and even through the Black Tortoise shell, he could feel the endless pressure.

Even his extremely terrifying physical body began showing signs of being unable to withstand it.

Cracks actually started to form on his body!

He was a cultivator of the Supreme level! The true master of this tunnel!

Who had ever forced him into such a state throughout ten thousand ages?

Just a mere array, how could it possibly be?

But the fact was right before his eyes, making it impossible for him not to believe. At this moment, he suddenly recalled an ancient legend. It was said that in the depths of the Chu Clan's Royal City, there once existed an ancient innate formation. Some said it was laid by the extraordinarily talented ancestor of the Chu Clan. Others claimed it was left by an "immortal" who once cultivated here and later left along the path to the heavens.

However, this statement had never been acknowledged by the Supreme Ancient Ancestors of the tunnel; they even believed that the array never existed!

Otherwise, a million years ago, how could the Chu Clan's Royal City have suffered a catastrophe? If there really was such a terrifying formation, capable of destroying even the Supreme, not only would the Chu Clan's Royal City be safe, but none of the Supreme Ancestors of the thirteen ancient clans would have survived!

So, no one believed that the formation had ever truly existed.

But now, this Supreme Ancient Ancestor suddenly felt a strong sense of unease. He had an intuition that this array should exist!

Boom!

A light of the Great Dao directly struck the Black Tortoise shell.

The incredibly powerful Black Tortoise shell emitted a violent tremor. This tremor caused numerous cracks to appear once again on the body of the Supreme Ancient Ancestor below.

This is a Dao injury!

An irreversible Dao injury within a short time!

The Supreme Ancient Ancestor was directly shocked.

The cultivators who had charged out following Qi Xiaoyu and Yiyi were also all stunned.

They looked in a daze at the array in front of them, whose power had suddenly increased by a thousand times, completely unsure of what was happening.

At this moment, Qi Xiaoyu once again began waving towards the Black Tortoise shell. But in reality, it was her heart that was truly at work!

The unique Seven-orifice Heart of Heaven and Earth!

Her heart could directly communicate with all spirits in the world, even the most brutal, unreasonable, and uncommunicable spiritual beings. Qi Xiaoyu had the ability to directly communicate with them!

This was a true innate divine ability.

Qi Xiaoyu only truly understood the power of her heart after entering the ancestral realm.

She directly engaged the incredibly defensive Black Tortoise shell, using the grudging spirit that remained within it, trying to convince it to leave the Supreme Ancient Ancestor.

However, the vital blood of the other side was too powerful, directly suppressing the Black Tortoise shell. So, even though Qi Xiaoyu successfully communicated with the Black Tortoise shell, trying to make it leave the array was extremely difficult. Therefore, Qi Xiaoyu directly invoked the ancient array deep in the ground of the Chu Clan's Royal City.

Before Chu Mo left, he had already anticipated that someone might directly attack here, so he had long taught Qi Xiaoyu and Yiyi how to manipulate the ancient array deep in the ground of the Chu Clan's Royal City. The strength of that array lay in the fact that as long as one had mastered the method, even a cultivator of the Holy Realm could manipulate it to trap a true top-level powerhouse!

Qi Xiaoyu now did this without hesitation, and even though it was her first time operating the array, she was not at all unfamiliar with it, drawing upon the powerful killing intent within the array to relentlessly attack the ancestral realm cultivator.

Not to mention those newly joined cultivators, even the monkeys were stunned!

Watching as the power of the array became increasingly strong and that once invincible figure became more and more difficult, everyone was so shocked that they almost lost the ability to speak.

At this time, someone finally recognized the origin of the trapped Supreme Ancient Ancestor within the array.

"Xu Tianxiao... he's Xu Tianxiao!"

This name suddenly left the group of cultivators who had grown up in the tunnels utterly shocked.

"It's actually him?"

"He's not one of the Supreme Ancestors of the thirteen ancient clans, so why is he attacking here?"

"It's clear that the thirteen ancient clans bought him off, surely promising unimaginable benefits. Otherwise, he wouldn't appear here!"

"Xu Tianxiao may not be one of the Supreme Ancestors of the thirteen ancient clans, but in our tunnel world, he has an unimaginably great reputation!"

Very quickly, information about Xu Tianxiao was spread from the mouths of those in the know.

This is truly a remarkable figure, peerless across ten thousand ages, who has been renowned for many years. The battle that made his name known throughout the Tunnel was his battle with another Supreme ancient ancestor outside the thirteen ancient clans.

The two fought at the pinnacle of the heavens in the Tunnel for over thirteen thousand years. In the end, that Supreme ancient ancestor was cleaved in half by Xu Tianxiao, and it's said even the primordial spirit was split!

Battles between Supreme ancient ancestors are extremely rare throughout the Tunnel. In endless years, there haven't been many such occurrences. Therefore, after that battle, Xu Tianxiao's name was remembered by countless people.

Those who just recognized Xu Tianxiao were also disciples of the former thirteen ancient clans, having seen portraits of Xu Tianxiao and read accounts of his life.

The fact that a Supreme-level ancient ancestor could be bought was indeed shocking, but then people's hearts were even more astonishingly shaken. They saw the two women over there, like fairy maidens, nonchalantly controlling the arrays, actually trapping such a great figure in the array. They seemed to be continuously retreating.

At this moment, Yiyi had taken over the task of controlling the array, while Qi Xiaoyu concentrated on communicating with the Black Tortoise shell, wanting to take the shell away from Xu Tianxiao.

Pfft!

Xu Tianxiao spat another mouthful of vital blood onto the Black Tortoise shell. This was his greatest reliance; if the Black Tortoise shell was lost, then this array would immediately cause him unimaginable damage!

So, no matter what, he couldn't let this dharma instrument fly away!

Meanwhile, Xu Tianxiao's heart was filled with hatred for those two exceptionally beautiful women.

He roared, "You two bitches, if I get the chance, I'll definitely teach you a lesson so severe you'll wish for life and death and get neither! Everyone in your Royal City will suffer endless torture!"

Bang!

Another ferocious killing intent violently struck the shell.

At the same time, the cracks on Xu Tianxiao's body… began to deepen!

The Black Tortoise shell, fixed by his two mouthfuls of vital blood, started trembling again.

"What the hell is going on?" Xu Tianxiao was utterly shocked and bewildered. Until now, he didn't know what was going on. This dharma instrument had clearly been consecrated by him for countless years, almost becoming his life dharma instrument, so why was it now constantly struggling and trying to escape?

Moreover, as the Black Tortoise shell struggled desperately to break free from his control, more and more attacks started rushing in through the gaps left by its struggles, beginning to launch a frenzy of strikes on Xu Tianxiao's physical body.

Xu Tianxiao's battle prowess was immensely strong, and his dao cultivation was unimaginably profound. Over endless years, he had never faced defeat.

Thus, in his heart, he held an unimaginable belief in his invincibility.

He let out a loud roar, using immeasurable computational ability, he began to reverse-engineer the array, actually attempting to break the array!

The strongest array… so what?

As long as it was created by a person, it must have a flaw!

At this time, Xu Tianxiao suddenly felt as if he had grasped a small flaw in the array. A look of wild joy appeared on his face. He couldn't help but laugh out loud, "Watch me break your array!"

His vast divine sense suddenly blasted into that very flaw.

But he failed to notice the mocking smile on Yiyi's face, who was presiding over the array.

"Break the array?" Yiyi laughed coldly, then waved her delicate hand.

The place which was initially a flaw turned into a terrifying storm of slaughter. It was the supreme Great Dao, directly engulfing Xu Tianxiao's divine sense.

"Ah!" Xu Tianxiao let out a miserable scream, his vast divine sense was instantly annihilated!

At that moment, the Black Tortoise shell hovering above his head suddenly shuddered fiercely… instantly breaking free from his control, flew billions of miles away. It unexpectedly directly broke out from the array and appeared, palm-sized, in Qi Xiaoyu's hand!

Boom boom boom boom!

A series of limitless killing intents blasted toward the now defenseless Xu Tianxiao.

A grand defense aura erupted from Xu Tianxiao, temporarily fending off this wave of attacks.

But he was already collapsing!

He let out a piercing roar.

"Give me back my dharma instrument… Give it back to me!"

Qi Xiaoyu gently patted the palm-sized turtle shell, smiling faintly, "Now, it's my dharma instrument."

As Qi Xiaoyu spoke, she directly communicated with the Black Tortoise shell with her mind, and grayish mist instantly appeared on the shell as a mysterious power surged from within!

This was something that had never happened since Xu Tianxiao obtained the Black Tortoise shell!

This mysterious power wiped away all of Xu Tianxiao's imprints left on it in an instant!

An exceedingly cute little white turtle apparition appeared above the shell. It looked affectionately at Qi Xiaoyu.

However, in the array, Xu Tianxiao let out an extremely miserable scream, spewing a large mouthful of vital blood!
