In order to live immortal, I changed a martial artist world to a xianxia world

“Brother Turtle!”
“It has been decades since we last met!”
Zhang Sanfeng’s face lit up with a rare smile as he addressed the enormous turtle before him. From his vantage point on the cliff earlier, he had caught sight of this old friend.
This was no ordinary turtle—it was the very creature Zhang Sanfeng had encountered during his first arrival at Wudang Mountain. Back then, the turtle had been locked in a fierce battle with a massive serpent. Inspired by their movements, Zhang Sanfeng had gained the initial insight into the art of Taiji.
That fateful encounter led him to settle on Wudang Mountain and establish the Wudang Sect.
For years, Zhang Sanfeng had sought this turtle, but no matter how thoroughly he searched, it eluded him. He had assumed the turtle had left the area. To see it again now, after so long, filled him with nostalgic joy.
The turtle’s intelligent eyes glimmered as it regarded Zhang Sanfeng, before slowly turning and ambling away.
“Leaving so soon?” Zhang Sanfeng chuckled ruefully.
He had just reunited with this old friend, only to see it depart again.
But then, something curious happened—the turtle stopped a dozen meters away and turned to look at him. Its expressive eyes seemed to convey a message.
“Wait,” Zhang Sanfeng murmured, his brows furrowing. “Do you want me to follow you?”
As if in response, the turtle gave a deliberate nod.
Stunned, Zhang Sanfeng stood still for a moment before stepping forward to follow. Satisfied, the turtle resumed its pace.
Thus began the journey—an aged man and a divine turtle meandering through the vast expanse of Wudang Mountain.
……………………………………………………………………………………………………..
As the hours passed, Zhang Sanfeng noticed something unusual—the turtle’s speed remained consistent, no matter the terrain.
Curious, Zhang Sanfeng quickened his own pace, testing the turtle. To his surprise, the creature also accelerated, maintaining the same distance between them.
“Truly a divine being!” Zhang Sanfeng exclaimed, awe written across his face.
The turtle’s extraordinary size was already proof that it was no ordinary creature. Its ability to match his speed confirmed its otherworldly nature.
Despite his questions, Zhang Sanfeng felt an inexplicable certainty—this journey would lead to an incredible opportunity.
An hour later, the turtle slowed its pace. Before them loomed the entrance to a hidden cave.
“A cave like this in Wudang Mountain?” Zhang Sanfeng muttered in amazement. “So this is where you’ve been all these years.”
The cave was well-concealed, a perfect hiding spot for a being as unique as the turtle. Zhang Sanfeng now understood why he had never been able to locate it before.
The turtle paused at the cave’s entrance, its gaze resting on Zhang Sanfeng.
“You want me to enter?” Zhang Sanfeng asked, reading the creature’s intent.
The turtle nodded once more, stepping aside to clear the path.
With a deep breath, Zhang Sanfeng walked into the cave.
The cave was modest in size, about as large as the Zhenwu Hall on Wudang Mountain. Zhang Sanfeng’s gaze swept over the interior, searching for what the turtle might have wanted him to see.
“What could it be?” he murmured.
Though nothing about the cave seemed extraordinary at first glance, Zhang Sanfeng trusted the turtle’s purpose. His senses heightened, and he began a meticulous examination of the walls.
Soon, he stopped before a particular section of rock.
“This wall…” Zhang Sanfeng’s eyes narrowed in thought. Though outwardly unremarkable, the wall exuded an almost imperceptible energy.
Curious, Zhang Sanfeng placed his hand on the surface.
The moment his fingers made contact, a blinding golden light erupted from the wall, forcing him to shut his eyes.
When the brilliance finally faded, Zhang Sanfeng opened his eyes to a breathtaking sight—the stone wall had transformed into a pristine jade tablet. Inscribed upon its surface were densely packed characters radiating profound wisdom.
“This is…” Zhang Sanfeng’s voice trembled as he read the title aloud.
