I Fabricated the Techniques, but my disciple really mastered them?

"You won't be disappointed, young friend."

The colossal turtle spoke, opened its mouth, and exhaled a small turtle shell. The shell was of a pale azure color, shrouded in a faint luminescence. Although it did not reveal a powerful aura, Xu Yan instantly recognized the extraordinariness of this shell.

Inside the shell, it seemed as if it contained its own universe.

"This is the Prime Tortoise Carapace, a chance acquisition of mine, and it can be considered a supreme treasure. What do you think, young friend?"

The colossal turtle said in a deep voice.

"Indeed, this Prime Tortoise Carapace is extraordinary."

Xu Yan nodded, indicating his approval.

"Speak then, what kind of deal do you want?"

The colossal turtle said in a deep voice, "My deal is simple. When you, young friend, become powerful, help me capture a cluster of Domain Rhythms!"

Xu Yan raised an eyebrow. Capture a cluster of Domain Rhythms?

To capture the Rhythms of Domain, as of now, he was not capable of doing so.

Unless he broke through to the Domain Realm, then it might be possible.

The Rhythms of Domain are profoundly mysterious, not as easy to capture as the rhythm of Dao principles. It involves the fundamental rhythms of the Way of Domain itself.

"The Rhythms of Domain are indeed precious, and capturing them is no easy feat."

Xu Yan did not immediately agree.

"This Prime Tortoise Carapace is much more valuable than a cluster of Domain Rhythms. It contains some mysterious power, even the way of the Prime Tortoise itself.

"However, after all, I am the one seeking your help, young friend. So, if one day you help me capture a cluster of Domain Rhythms, I will additionally bestow upon you a major secret. This secret holds a great opportunity, which of course, comes with certain risks," said the colossal turtle after pondering for a moment.

"What kind of great opportunity?"

Xu Yan was somewhat curious.

The great opportunity mentioned by the turtle must lie beyond the Domain, and it would be some time before he had the strength to explore it.

"An opportunity much greater than this Prime Tortoise Carapace, a truly great opportunity," said the colossal turtle in a deep voice.

"With such a great opportunity, why don't you seek it yourself?"

Xu Yan tapped on the turtle's back with his foot.

"I do not have the strength, and that place also fills me with dread... This matter is too profound. When you, young friend, are strong enough, I will naturally tell you all about it.

"Furthermore, if you young friend can obtain this great opportunity, I will follow you for the rest of my life," the colossal turtle said with a sigh.Nôv(el)B\\jnn

Xu Yan's brow furrowed. The turtle was not lying; when it spoke of that opportunity, a flicker of fear unconsciously surfaced in the depths of its eyes.

"Alright, I agree!"

Xu Yan nodded after a moment of contemplation.

Since it was a great opportunity, he would seek it once he became powerful enough.

"In that case, thank you, young friend!"

The colossal turtle breathed a sigh of relief.

Xu Yan waved his hand, and the Prime Tortoise Carapace fell into his palm.

Without examining it closely, he put it away immediately, then asked, "Old turtle brother, how shall I address you?"

"Cang Hai," replied the colossal turtle after a moment of thought.

"Azure Sea Turtle?"

Xu Yan muttered to himself; he had never heard of this turtle before.

He then tossed a Communication Talisman to the Azure Sea Turtle, saying, "Keep this talisman. If I manage to capture the Rhythms of Domain, I will naturally contact you. If there are any questions, I will also use this to contact you."

The Azure Sea Turtle was taken aback, looking at the talisman, and asked, "How far can it transmit?"

"My junior brother said that within the Domain, communication is possible anywhere, though it hasn't been tested. But within the Divine Realm, communication is surely possible," Xu Yan replied.

Having said that, Xu Yan rose into the air and vanished into the Domain in an instant.

The Azure Sea Turtle stared at the talisman, somewhat dazed, murmuring to itself, "Since when did things like this exist in the Taicang Domain? Why do I feel that this person's Martial Arts do not belong to Taicang Martial Arts?

"Strange indeed, how can there be Martial Arts that aren't Taicang's in the Taicang Domain? Moreover, when it comes to Martial Arts, Taicang is supreme; no one would abandon the strong for the weak.

"No, his Martial Arts are stronger than Taicang Martial Arts!

"Has something changed in the Taicang Domain? Could it be that Taicang is not dead and has developed stronger Martial Arts?"

At this thought, the Azure Sea Turtle was startled, then shook its head, "Impossible, Taicang cannot be alive."

```

Looking up at the firmament, he sighed and his figure slowly vanished into the sea.

After leaving the Azure Sea Turtle behind, Xu Yan took out his flying boat and drifted on the sea, while sitting inside the flying boat, he took out the Prime Tortoise Carapace.

"Azure Sea Turtle, how powerful you must have once been!"

Xu Yan wondered curiously to himself.

He didn't directly attempt to seize it by force but made a trade with the Azure Sea Turtle instead, and one of the most important reasons was that the turtle, seemingly at the Immortal Realm, could potentially unleash an incredible level of strength in a life-or-death situation, impossible to estimate.

Of course, if that were the case, the Azure Sea Turtle would likely pay a heavy price, and perhaps never recover thereafter.

It was for this reason that the turtle wasn't willing to fall out with him.

Another factor was that the Azure Sea Turtle sensed Xu Yan's extraordinary potential. Considering him a monstrous talent of the domain, it decided to make a trade and foster a good relationship.

Xu Yan looked at the Prime Tortoise Carapace, his face full of pleasant surprise.

Inside the shell was a small space, akin to a mini-domain, filled with spiritual energy that absorbed the spiritual energy from around the domain, providing an area for martial artists to engage in dedicated cultivation.

"No wonder it couldn't be stored inside a storage ring."

Xu Yan was delighted, for the Prime Tortoise Carapace indeed was a supreme treasure.

"With its own mini-domain and self-contained rules, perhaps it's possible to contemplate the Establishing Dao Realm inside."

Thinking this, Xu Yan released a surge of Divine Origin Power, which poured into the Prime Tortoise Carapace, starting the process of bonding with it and nurturing it within his body.

As the Prime Tortoise Carapace was nurtured by the Divine Origin Power, its dense glow grew brighter, and on its back, patterns flashed like the flowing of Dao Principles.

The flying boat drifted on the vast ocean, and Xu Yan, immersed in the process of bonding and nurturing the Prime Tortoise Carapace, was unaware of where the boat might be drifting.

As time passed, finally Xu Yan's mind connected with the Prime Tortoise Carapace.

With just a thought, he could see the mini-domain inside the carapace.

"I finally did it!"

A joyful expression spread across Xu Yan's face.

With a single gesture, the luminescent mist around the Prime Tortoise Carapace intensified, and Xu Yan's figure instantly vanished from the spot, leaving only a small tortoise shell inside the flying boat.

"This is the space within the Prime Tortoise Carapace?"

Xu Yan looked up at his surroundings, his face showing shock.

Only upon truly entering the mini-domain within the Prime Tortoise Carapace did he deeply feel the marvel of this small domain.

The spiritual energy was thick, condensing into a light mist.

Moreover, because he had bonded with and nurtured the Prime Tortoise Carapace, Xu Yan could clearly feel that this small space had its own set of rules, akin to the Domain Dao Rule.

"This is like a small domain, and the Prime Tortoise Carapace itself forms Dao Principles, orchestrating this mini-domain..."

In that instant, Xu Yan's mind became clearer, and the Martial Arts Techniques of the Establishing Dao Realm appeared one by one.

"What kind of power did the Prime Tortoise possess in its lifetime?"

Xu Yan was astounded.

The shell contained its own mini-domain, with rules in motion—were these rules possibly the realizations from the Prime Tortoise's cultivation?

"The strength of the Azure Sea Turtle, probably isn't inferior to that of the Prime Tortoise."

Xu Yan clicked his tongue in amazement.

Yet such a powerful Azure Sea Turtle had been reduced to such a state—what kind of catastrophe had it encountered?

"Even such immense strength can fall, can be reduced to this. I'm only in the Void-breaking Realm; I must be even more careful and guard against arrogance and complacency!"

Xu Yan cautioned himself inwardly.

He then remembered the towering figure he saw when crossing the wilderness.

Was the owner of that towering figure still alive?

Or perhaps, has he also fallen?

What terrible adversary did he encounter?

"Only master is truly invincible!"

Xu Yan sighed inwardly.

"This place is perfect for contemplating the Establishing Dao Realm. Once I merge the Prime Tortoise Carapace into my Mountains and Rivers, it will help me understand the Establishing Dao Realm even better, and lay the foundation for my breakthrough into the Domain Realm."

Xu Yan sat cross-legged within the Prime Tortoise's domain, his Primordial Spirit sensing the rules of the domain, and began comprehending the Establishing Dao Realm.

With a thought, a Yu Zhu appeared and floated before him.

"Yu Zhu, Prime Tortoise's domain, with this as my aid, I should be able to understand the Establishing Dao Realm quickly, while also laying the groundwork for my breakthrough into the Domain Realm."

Xu Yan pondered silently.

A flying boat, drifting aimlessly in the sea, had long since diverged from any known route in the Azure Sea Sphere.

Inside the boat, there was only a small tortoise shell, and this shell, no longer radiating the misty luminescence, seemed to have grown a layer of moss, making it look like an ordinary tortoise shell, left behind after the death of the creature within.
