Before they entered the Great Thousand Battle Domain, the green sparrow had said that on this one-way road of blood, there were at least over a thousand battlefields, nearly a hundred mysterious forbidden zones, and forty-nine Immortal Heavenly Passes of various sizes! Among them, those mysterious forbidden zones were classified as the most dangerous terrors. This information put Lin Xun on alert. He wondered just how terrifying the so-called mysterious forbidden zone in Gathering Netherworld that the green sparrow was talking about was. Lin Xun said after some thought, “I'd actually like to explore if the opportunity arises.” The green sparrow said, “It will take around two months to walk through Gathering Netherworld, after which we’ll reach the first Immortal Heavenly Pass, which is also called the Immortal Imperial City... It's still too early to talk about this, you'll naturally understand when you get there.” Lin Xun nodded as he trod through the bone tunnel into the depths of the starry sky. There was a strange teleportation power permeating this path, and walking on it gave one the feeling of traveling through time and space and roaming the universe. In just the time it took to drink a small cup of tea. A spatial swirl filled Lin Xun’s vision, and he found himself in an unfamiliar world. In the leaden sky hung a purple sun. Its glow was so dull that it dyed the heaven and earth in a dim color. The whistling of the wind sounded like someone’s whimpers, chilling to the bone. All kinds of cold currents flowed in the atmosphere, giving people a depressing feeling. At the moment, Lin Xun was standing on the bank of a river. Further ahead was a sparse forest where the trees were all bare, scorched, and dried, and they even emitted wisps of black smoke. The green sparrow suddenly said, “Ancient rumors say that in the last epoch, every being’s soul would enter the netherworld after their death. The souls would walk the Yellow Spring Road, cross the Bridge of Forgetfulness, drink Meng Po’s soup, and then enter the Six Paths Division where they would be reincarnated based on the good and evil they had done during their lifetime. “In the netherworld, there are many other mysterious and scary places, such as the Gates of Hell, the Eighteen Layers of Hell, the River of Sinful Blood, and so on. “The administrators of the netherworld are even more terrifying. They possess unfathomable and supreme abilities. They are proficient in the dao of fate and can control destiny. In our current era, that kind of cultivation means that they have at least peeked at some of the mysteries of the dao of fate.” Lin Xun's eyes narrowed. He had once heard from the green sparrow that the last epoch was called the Immortal Martial Epoch, while the current one was the Spirit Martial Epoch. However, all he knew was the concept. He had zero idea what the last epoch looked like, and what it had gone through that led to its eventual destruction. Perhaps only in the Eternal True Realm would there be more opportunities for him to understand the secrets behind the epoch change. Of course, one could also achieve this if their cultivation reached to the point of allowing them to peer into the principle of eternity and comprehend the law of fate. At that point, one could stand above all daos and watch the changes of worlds and eras as they pleased, thereby perceiving the marvelous flow of time as well as the mysterious rise and fall of the epochs. “In Gathering Netherworld, there is only one path to life called the Yellow Spring Blood Road. See that purple sun in the sky?” asked the green sparrow whose gaze was on the horizon. “Here, that purple sun shines eternally alone, and the Yellow Spring Blood Road is under its shine.” Lin Xun looked over and decided to waste no time. Gathering Netherworld was very vast, and the scenery was eerie. Every terrain was draped in strands of depressing energy, as if it was the real netherworld. Traveling in here, all it would take was one careless step to get lost and never find the way back. Cultivators below the Emperor Stage simply didn't dare to step into this place. Fortunately, Lin Xun had the green sparrow to guide his way and wasn't afraid of getting lost. Lin Xun’s figure flashed like a comet as he teleported, repeatedly changing directions along the way. He passed one bizarre and unpredictable area after another, taking frequent turns like he was in a big labyrinth. Roughly an hour later. An arch bridge made of stone entered his vision, stretching across the void and extending into the depths of the gray mist. The bridge was paved with mottled bluestone, with both sides protected by artfully carved parapets. Underneath the bridge, clouds drifted like rolling mist waves. Murky airflows that stunk of blood spewed out from the depths of those clouds, revealing a corrosive aura. Vaguely, one could hear the howls of ghosts that sent chills down their spine. Seeing this scene, Lin Xun became solemn. This stone arch bridge as well as the scenery around it was permeated with an ominous feeling. The green sparrow quietly transmitted, “Rumor has it that this is the Netherworld’s Bridge of Forgetfulness in the Immortal Martial Epoch. Under it flows the Waters of Forgetfulness. In those waters, there is a pool of blood called the Blood River Pool. “Any soul that falls into the netherworld, after passing the Bridge of Forgetfulness, will all have their memories erased. Then, they will be detained in the netherworld hell until they re-enter reincarnation. “Those who have done too much evil in their lives, when stepping onto the Bridge of Forgetfulness, will fall into the Blood River Pool and be submerged for eternity to suffer endless pain. “It’s said that on the east and west sides of the Bridge of Forgetfulness, there was originally a Yellow Spring Palace and a Netherworld Terrace that leads to the Eighteen Layers of Hell. But this is only what legend says. No one could claim whether it’s true or not. “After all, these are all rumors from the last epoch and can no longer be verified.” Lin Xun was shocked as he listened. The Netherworld, the River of Forgetfulness, the Yellow Spring Hell, and the dead souls in the Blood River Pool! All of this sounded inconceivable. If it really existed in the last epoch, then what kind of spectacle could it have been? The green sparrow continued, “Stepping onto the Bridge of Forgetfulness is like stepping onto the Yellow Spring Road – the road to hell. You will encounter all kinds of dangers along the way, so be prepared.” Lin Xun nodded and summoned the Limitless Abyss Sword Cauldron. Only then did he set foot on the stone arch bridge in the air. As he walked on the bluestones filled with the mottled aura of time, the vaporizing mist under the bridge emitted a unique aura of the netherworld, a kind of very different coldness that drilled into one’s bones. Even with Lin Xun's spirit sense, he still failed to probe through what was transpiring in the thick mist. Instead, his spirit sense was imposed with incomparable chill and pressure. Lin Xun suddenly noticed something about the parapets on both sides of the bridge. The faint patterns carved on them were uncanny: bloody flowers covering the ground, turbid Yellow Spring water pouring out endlessly... There were also carvings of various solemn buildings with strange inscriptions: Six Paths Division, Netherworld Palace, Ten Great Yamas, Pool of Rebirth... There were also carvings of all kinds of demons, and a few scenes of purgatory... Although the details had become blurry, they still emitted a mind-stirring charm in this gloomy world. Lin Xun walked slowly as he constantly observed, only to get more and more surprised in his heart. Can it be that what is depicted here is the netherworld of the last epoch? Suddenly, the Limitless Abyss Sword Cauldron produced a strange buzz. On inspection, the Nirvana law power being nurtured inside had quietly transformed into a lotus pattern. At the moment, it was emerging and diffusing billions of magnificent hazes. Lin Xun narrowed his eyes. Not waiting for him to react, the lotus pattern released a bundle of law power light that gently screened the parapets of the Bridge of Forgetfulness. Lin Xun instantly saw the various depictions of the past netherworld being copied one by one and imprinted in the lotus pattern. "Ehh? This law power of yours...“ the green sparrow was startled. “It can't be absorbing the netherworld origin power of this place, can it?" The bird seemed to have lost its composure, which was rare. Lin Xun immediately realized that this was the green sparrow’s first time encountering such a thing despite its vast knowledge. It made him wonder why the Nirvana law power would actively copy the scenes in the carvings. Do those depictions hide a mystery about the netherworld or something? While observing, Lin Xun asked, “Have you ever heard of any grade of law power in this world that can do this?” The green sparrow didn’t have to think twice, “I only dare to confirm one thing: this is absolutely not something an Earth Rank law power is capable of. As for Heaven Rank ones...it's hard to say...” Obviously, the green sparrow was also appalled and full of doubts. Lin Xun sank into contemplation. The endless calamity of ruin, the lotus blooms in solitude... As something that the Master of Fangchun Mountain waited eons for, how can the Nirvana of Transcendance’s law power be something ordinary...? Looks like I still underestimated it before. It’s far more mysterious than what I’ve known and imagined. In fact, Lin Xun was also aware that with his current cultivation, he could only control the Nirvana law power and Phoenix Flame of Order while simply being unable to understand their supreme principle. This was called knowing what it was, but not knowing why it was. Those who were able to understand a law power’s essence and wield it all surpassed the Ancestor Stage! Lin Xun took a deep breath and continued on his way. As he walked farther and farther on the Bridge of Forgetfulness, the lotus pattern never stopped copying the various scenes depicted on both parapets. It felt as though the Nirvana law power regarded these scenes as a kind of power and was constantly refining it for its own use, to supplement and perfect itself. This astonished Lin Xun even more. Along the way, the green sparrow was also so shocked that its pupils stopped moving and it couldn't even speak. Erudite and coming from the Immortal Imperial Yuan Clan, it had seen many weird and unimaginable things. However, this was the sparrow’s very first time seeing a law power performing such a magical ability, and at its own will at that, as if it had intelligence. After the time it took to savor a cup of tea. With a buzzing fluctuation, the lotus transformed into a dull gray streak and went back inside the Limitless Abyss Sword Cauldron. Also at this moment, Lin Xun realized that he had already arrived on the other side of the Bridge of Forgetfulness. This was perhaps the reason why the Nirvana law power had returned to the sword cauldron. “Truly mysterious...” lamented Lin Xun. This was his first time seeing such an abnormal change with the Nirvana law power. It was completely out of his expectation. Next to him, the green sparrow could no longer hold back its curiosity. It urged, “It absorbed and refined so many paintings about the netherworld. Quickly check if there’s been any change in your lifebound Emperor weapon.” This hadn’t crossed Lin Xun’s mind. He sank his spirit sense into the Limitless Abyss Sword Cauldron.
