Wind howled in his ears as Fang Yuan trekked through mountains and crossed waters. Even without using any Gu insects, his speed was extraordinary.
Once he passed beyond the area ravaged by the calamity, the terrain was no longer flat plains but rather dense forests and mountain ranges.
Southern Border was mountainous — this was one of its defining geographical features.
"I've been running for so long without any rest at all, yet I don't feel the slightest fatigue! And the most important thing is, I haven't used a single Gu insect."
At this moment, Fang Yuan had begun to grasp the special nature of this body.
A Gu Master's body, before being modified by Gu insects like the Black Pig Gu or White Pig Gu, was not much different from an ordinary mortal's body.
It was precisely the Dao Marks imprinted upon them that granted Gu Masters their extraordinary and wondrous physical abilities.
"This body of mine was transformed from the Supreme Immortal Fetus Gu, a Ninth Transformation Immortal Gu. It seems the Dao Marks on me are far from few. At the very least, the Dao Marks related to strength are absolutely far denser than what I had accumulated before!"
Fang Yuan silently assessed.
Ever since becoming an Immortal Zombie, he had been unable to feel exhaustion. But if he were to restore his original living flesh and run like this today, he certainly wouldn't have made it halfway before needing to stop and rest.
Fang Yuan sprinted and climbed through the thick, dense mountain forests. Treacherous rock faces became as level as a road under his nimble use of both hands and feet.
Fang Yuan was still stark naked, cutting through the deeply shaded forest like a streak of white foam.
The dense forest was laid out with crystal clarity in his field of vision. Even at his running pace, everything seemed frozen in place as he easily avoided every obstacle.
"In the terminology of Earth, this would be called dynamic visual acuity. My current dynamic visual is absolutely at its peak! This is definitely beyond human levels. My original body could only achieve this kind of performance by activating Gu insects."
In no time, Fang Yuan reached the summit of the mountain.
The dark forest that had filled his vision suddenly vanished, replaced by a vast, sweeping panorama — the sky soared high above towering peaks!
A great wind whipped through his long hair, sending it streaming behind him.
Fang Yuan caught his breath with three soft pants. Almost immediately, his breathing settled into a slow, relaxed rhythm, as if the frantic sprint had never happened at all.
His physical stamina was impossibly abundant!
The mountain wind was biting cold. Fang Yuan was still completely naked, without a single stitch of clothing, yet he felt not the slightest chill.
His heartbeat quickly returned to normal, each pulse slow, deep, and immensely powerful.
Fang Yuan gazed into the far distance.
His field of vision was extraordinarily vast.
Within a range of ten thousand paces, every detail of the landscape was perfectly visible.
With a light sweep of his gaze, Fang Yuan's eyes suddenly froze, and his expression sharpened slightly.
He had discovered traces of battle.
"So Taibai Yunsheng and Hei Loulan encountered other Immortal Gu Masters here while escorting my body. The two sides clashed."
In a flash, Fang Yuan leaped directly off the mountaintop.
With a resounding thud, he landed squarely on a rocky outcrop three zhang below.
Completely unscathed.
He didn't even feel a tingle in his feet!
However, the surface of the rock beneath him was covered in a web of spider-crack fractures.
A sharp gleam flickered through Fang Yuan's eyes before vanishing. He began experimenting further.
The drop height grew progressively larger — starting from three zhang, it quickly increased to five zhang, eight zhang, twelve zhang.
Converting to Earth units, three zhang was nine meters, five zhang was fifteen meters — already the height of a five-story building. Twelve zhang was already the scale of a skyscraper or transmission tower.
Twelve zhang was nowhere near Fang Yuan's limit. The height kept climbing all the way to fifty zhang.
At that point, Fang Yuan finally felt a tingling sensation in the soles of his feet. Growing bolder by the moment, he deliberately landed on different parts of his body several times.
Chest-first, back-first, and so on. Each time, he smashed craters into the hard mountain stone.
Fang Yuan climbed out of the craters, completely nonchalant.
In fact, the all-over tingling sensation actually felt rather pleasant!
Drawing a deep breath, he leaped down once more.
This time, the drop was fifty-eight zhang.
At this height, it no longer mattered to Fang Yuan. What mattered was that this time, he decided to land on his head!
Thud.
A muffled impact. Fang Yuan's entire head drove deep into the stone.
Bracing both hands, he pulled his head free from the rocky pit.
The skull was the hardest part of the body, but Fang Yuan could still feel something.
He felt a tingling across his scalp, and his head was a little dizzy.
But the dizziness lasted only two or three breaths and was extremely faint. The cool mountain wind blew past, and it dissipated without a trace.
Fang Yuan touched his head and then carefully inspected his entire body.
Not a single wound. He hadn't even lost a single hair!
In a word — completely unharmed.
Fang Yuan tried pulling out his own hair and discovered it was remarkably tough. It took considerable effort to yank out just one strand.
The hair was slightly thicker than an ordinary person's, so black it gleamed, giving the impression of an extremely fine steel wire.
He pulled harder, but it wouldn't break — astonishingly resilient.
