In ancient times, there existed a great turtle, known as the Xuan, whose lifespan extended over thirty thousand years!
It is said that, in its normal activities, it breathed only three times a day.
When it fell into a deep slumber, it breathed only once every three hundred years.
During these three hundred years, it remained motionless like a mountain, resembling a dead object with no signs of life. When it took a breath after three hundred years, it devoured an entire region of Heaven and Earth Qi, a spectacle truly alarming.
"In my early years, I acquired a basic doctrine known as 'Turtle Spirit Armor'. It allows one to imitate this creature's breathing, regulate the leakage of Essence Qi, while also concealing one's own mana fluctuation."
"Although this doctrine is basic, I have also cultivated body refinement techniques similar to it, and possess protective treasure armor made from Xuan Turtle Remains, which emits the aura of the Xuan Turtle."
