The mountain walls were covered with the traces left by the golden wind.
A multitude of white sky Devils lived in this basin.
Several Giant-like humanoid white sky Devils, each tens of feet tall, stood under that Gold and Silver Mountain, continuously attacking the Double Lung, damaging its lung qi, forcing it to constantly breathe and exhale the golden wind lung qi.
This scene sent a shiver down Yu Ziqing's spine.
He could even sense that the two gigantic lung lobes, like the Gold and Silver Mountains, were full of life, with no sign of decay.
Looking again at the ribcage encasing the lung lobes, their owner had likely been dead for countless years.
The bones were like gold and iron, having been scraped by the golden wind for countless years without leaving a mark, with the remaining fur intact.
Adding to that a remnant of demon qi, one could surmise it was the remains of a certain Demon God.
He decided to investigate later to see if any Demon God had fallen in the past, capable of producing such mountainous gold and silver lungs.
After waiting for three days with no Devils emerging, Yu Ziqing grew impatient.
"Lou Huai, stay here, don't go in."
Yu Ziqing instructed, watching for the change of day.
Though the Abyss did not see the sun, it had day and night, with the yin qi being stronger at night when the Devils became more active, whereas during the day, most Devils preferred to stay inactive.
When the yin qi was at its weakest one day, Yu Ziqing, like a gecko, began to stealthily climb down the cliff from the farthest point from Double Lung Mountain.
All manner of Devils rested, taking advantage of the few moving during the day, even the giant Devils attacking Lung Mountain daily paused for a while, allowing the Double Lung Mountain to rest.
After squatting for two hours, Yu Ziqing gathered his strength, relying solely on his physical body, moved along the ground, and slowly infiltrated the underground cave.
Finding dozens of egg-like golden lumps, sensing their power, Yu Ziqing quietly pocketed three.
However, just as he emerged from the cavern, a sound like rusty steel scraping echoed from deep within.
Those white sky Devils, previously asleep, immediately opened their eyes.
The towering giants, one by one, sat up.
"Uh-oh," Yu Ziqing muttered to himself.
He had previously guessed that the number of white sky Devils compared to the Black Sky Devils was at least two or three times less, and their egg production was similarly fewer.
He had only seen a few dozen in that cave.
These creatures surely valued these eggs more than the Black Sky Devils did.
Unexpectedly, without spotting him, they could detect when the golden egg left the cave at an instant.
Yu Ziqing popped a Devil Pill into his mouth, instantly covering his body with Devil Patterns, a pitch-black Double-headed Black Snake appeared at his waist, shattering to reveal a black tattoo crawling onto his shoulders.
Strength bursting through him, Yu Ziqing shot forward like an unsheathed sword toward the cliff.
His hands like steel nails, pierced the cliff face; his form became a blurred shadow advancing rapidly.
Behind him, the golden wind gathered, constantly assaulting the cliff, like countless steel blades striking Yu Ziqing with ringing sounds of metal clashing.
Suddenly, sensing a crisis, Yu Ziqing's power exploded, and he leapt into mid-air.
The next moment, a huge bone struck the cliff, the tremendous force instantly shattering everything within a hundred-foot radius.
The fierce qi gusts swept past, causing Yu Ziqing to struggle for breath, his lung qi damaged.
Bracing against the winds, he bypassed any unnecessary means, sprinting directly out of the basin.
Lou Huai, who had been waiting all the while, watched Yu Ziqing return and immediately transformed into a black mist, hiding in Yu Ziqing's shoe.
Yu Ziqing glanced back to see a golden beam of wind shooting skywards from the basin, with a large group of white sky Devils roaring out.
Grinning, Yu Ziqing gauged his direction, his body exploding with power, breaking into a mad sprint.
Having fallen into Devilic, the Fifth-tier body cultivation's explosive speed was not inferior to flying escape, with even greater stamina, just less discreet.
And in this wide open and barren land, it could not have been more suitable.
Yu Ziqing unleashed his full strength, heading directly toward the Black Sky Devil territory.
Not a day passed before he heard the roaring of the Nu River, and Yu Ziqing glanced back to see the white sky Devils trailing far behind.
He slowed slightly, suppressing his own power, surrounded by Black Sky Devil God Qi, and being fully Devilic, none could claim he didn't belong to Black Sky Devils.
Crossing the mountain top, Yu Ziqing proceeded unhurriedly, even casually swatting a blocking Black Sky Devil aside.
He nonchalantly leapt into the Nu River.
Moments later, white sky Devils arrived, with the harsh golden wind wreaking havoc, causing some weaker Black Sky Devils to fall over, their lung qi depleted.
This stirred up the hornet's nest, for those Black Sky Devils, that hadn't had a fight or anything to kill, only to have one another to feud with daily, could not tolerate this slight.
Without even a rallying cry, the brawl commenced.
More Black Sky Devils gleefully charged in, joining the fray against the white sky Devils, as killing other Devils was far more exhilarating than killing their own kind.
