The sword qi that was covered in outlandish runes eventually went up in smoke. “Hoo~” Lin Xun breathed out as he was inwardly startled. Earlier, when listening to the green sparrow's pointers, he had been somewhat unimpressed. However, after having actually killed an Undead Monarch, he truly understood how terrifying such a spirit fiend was. Who would dare to imagine that this Undead Monarch's obsession would actually be a sword qi? Furthermore, it was also too bizarre, covered in obscure and treacherous runes! “Hm?” Lin Xun suddenly noticed a broken jade slip. It was left by that Undead Monarch, old and mottled. Lin Xun retrieved the slip and probed it with his spirit sense. “Father, Mother said that you're coming back soon, is that true? You've been gone for three hundred and nineteen years and eighty-seven days. Mother and I miss you so much... Father, I’m waiting for you to come back for my wedding. If you don't, then I won't get married...” The words and phrases in the jade slip were intermittent and feeble, and the majority of the content was missing. It was only with great difficulty that Lin Xun was able to see two complete sentences. Reading them, he fell silent. His heartstrings trembled as if tugged by an inexplicable force. Since the broken jade slip was the only thing that Undead Monarch had carried, he had expected it to hide a great secret. But who would have thought... This was actually a letter from home. A letter permeated with his daughter's deep longing. She even remembered how long her father had been gone to the days, something that only one’s closest family would pay attention to. When this Undead Monarch was alive, he...should also have missed his daughter very much, right? Lin Xun couldn’t help but think of Zhao Jingxuan and Lin Fan at Mind Cleansing Peak. Although they had only been separated for over a year, they probably had been thinking and worrying about him, right? At this thought, Lin Xun suddenly smiled. Lin Fan, that kid, surely wouldn’t think about it too much, for young people did not know the taste of sorrow. On the contrary, Jingxuan... She must have already thought about him more than once... Lin Xun couldn’t help but sigh softly and carefully stowed away the old and mottled jade slip. Such an item was ordinary, but it was also very precious and ought to be treasured. As for killing the Undead Monarch, he had no regrets. The other party was only a spirit fiend transformed from an obsession. The original person had probably long fallen during the destruction of the last epoch. “Regardless of the change of epochs and worldly affairs, familial love remains eternal and unchanging...” mumbled Lin Xun. With the fall of the Undead Monarch, the undead inhabiting this ravine seemed to realize how formidable their opponent was. They disappeared into the boundless mist, never to be found again. Lin Xun organized his thoughts before looking down at the bottom of the ravine. The brilliant halo was the size of a cattail leaf fan. Suspended above the dark brown soil, it dispensed a magnificent drizzle of colorful dao light. Upon closer inspection, there was a strange and pure ancestral origin power surging within that mass of light. Wisps of great dao aura filled the air, dazzling to look at. The green sparrow jumped on Lin Xun's shoulder and clicked its tongue, “Your luck isn’t half bad. The quality of this Ancestral dao origin can be classified as first-tier. In the old days, the emergence of an Ancestral dao origin one would definitely cause a large-scale bloodbath.” Seeing Lin Xun walking over to take this Ancestral dao origin, the green sparrow hurriedly advised, “This kind of divine object is left from the last epoch, so it can't be taken away. If you use force on it, its power will instantly dissipate until there’s nothing left.” Lin Xun stopped dead in his tracks and asked, “What should I do then?” The green sparrow said, “Meditate next to it and refine its power.” Lin Xun thought for a moment before waving his sleeve and setting up the Nine Hells Divine Binding Array around him. Then, he sat down cross-legged next to the Ancestral dao origin and started a meditation session. As he breathed in and out, the drizzle of dao light spewed by the Ancestral dao origin acted like it was being pulled, turning into wisps of light streaming toward his mouth and nostrils. Upon entering his body, they instantly turned into a searing torrent and rapidly expanded. Right that instant, all of Lin Xun's pores relaxed. His meridians, acupoints, organs, bowels, limbs, bones, and every inch in him erupted with a hungry pulse, like countless small mouths waiting to be fed as they cried and jumped around. Even his True Self Emperor World produced unprecedentedly strong rhythms, rumbling and boiling up. As the searing torrent of qi was continuously drawn from the Ancestral dao origin into him, Lin Xun felt so comfortable that he almost couldn't help but moan. This feeling was seriously marvelous. It was like eating a sumptuous and tantalizing meal after one had been hungry for a long time, like a long-dried-up desert receiving a sweet rainfall... Lin Xun had never experienced such a wonderful feeling before this since he had started his cultivation journey. The power of the Ancestral dao origin of the previous epoch that had been buried here was undoubtedly magical! The mass of Ancestral dao origin had shrunk to the size of a baby's fist. Lin Xun, on the other hand, clearly perceived that his entire cultivation had skyrocketed by a large chunk, having stepped from the early stage of the sixth realm to the mid stage! The change was so great that he couldn’t help but marvel out loud. Each of the nine realms of the Emperor Stage was a heavenly barrier. The higher one was on the ladder, the harder it was to improve. Even a super genius would gradually slow down in advancement speed as their cultivation level increased. As for the general cultivators, whether they could break into the next realm was already a question. Therefore, having seen such a huge change in his cultivation produced in merely four hours, how could Lin Xun not be surprised? Of note, his dao foundation was extremely thick and solid compared to the average cultivator in the same realm. He didn’t even have a match in the Supreme Emperor Stage. So, his cultivation leaping from the early stage to mid stage in one go was already considered lightning speed! “No wonder all the experts who have ever entered the Undead Soul Domain would end up fighting over Ancestral dao origin. This kind of treasure is indeed too incredible...” Reaching this conclusion, Lin Xun quickly discarded distracting thoughts and continued to cultivate. The clump of Ancestral dao origin had been completely refined and was no longer available, while Lin Xun's cultivation had started progressing toward the late stage of the sixth realm! Feeling the change in himself, Lin Xun was completely convinced. “One month... If I seize the time, it might be enough for me to take a new step forward in my dao...” he muttered. “It was just good luck that you managed to monopolize a top-tier Ancestral dao origin. You won't be as lucky next time,” commented the green sparrow, pouring cold water on him. Lin Xun laughed, not quite agreeing to this. His figure flickered as he teleported out of the ravine, continuing his search along this cold, silent, and misty void. Half a day later, he sighed, “You really have the mouth of a crow....” He had slain another handful of undead without finding any more Ancestral dao origins on the road. “You're blaming your bad luck on me?” the green sparrow glared at him. Right at this moment, a hideous roar echoed in the distance that revealed craze and tyranny. The green sparrow immediately said, “Someone’s having their mind invaded by the obsession of the undead. If there are no unexpected variables, then they have become disoriented and fallen into madness.” Lin Xun spread his spirit sense and vaguely captured the sound of a battle. Any battle that took place in the Undead Soul Domain was bound to be related to Ancestral dao origin! “Let’s go and take a look.” Lin Xun teleported in that direction. After experiencing the magic of one Ancestral dao origin, how could he miss any opportunity to compete for it? “Greed really makes people crazy...” lamented the green sparrow. “What greed? This is called the great dao race. Ancestral dao origins are originally ownerless, so if others can grab it, why can't I?” retorted Lin Xun as he quickened his pace. Soon, a massive floating land came into view. A free-for-all fight was being staged on it. The figures of Emperor experts flashed by, each of them displaying monstrous power. Swords, spears, battle axes, hooks, tridents, seals... All kinds of imaginable and unimaginable Emperor-grade weapons wrapped in brilliant dao light streaked across the field. They clashed with the sound of thunder, which was also interspersed with fighting noises, angry roars, ear-piercing screams, and wails... This was indeed a big scuffle. At a glance, Lin Xun spotted at least four groups from different camps. As they were all Emperors, even the residual power sweeping out from their collision was destroying the sky and earth. Not far from the battlefield, a huge, seemingly stagnant, spatial vortex was quietly suspended in the air. The depths of the vortex from time to time spewed out a beautiful, colorful rain of light. That was clearly the aura of an Ancestral dao origin, and an extraordinary one at that! Naturally, it was also the trigger of this big scuffle. “Hmm?” Lin Xun suddenly noticed many more auras lurking around this floating continent. They were keeping note of the scuffle while waiting for an opportunity to move. Lin Xun immediately knew that it would not be easy if he wanted to take this Ancestral dao origin all to himself. Too many opponents were watching intently! Thinking about it for a bit, Lin Xun collected his aura and concealed himself in a grayish-white fog not far from the floating continent. “Retreat!” In the scuffle, some Emperors realized that their chances weren’t high and decisively withdrew. Meanwhile, many of the fighters had noticed that there were more opponents lurking in the vicinity. Knowing their situation wasn’t good, they also prioritized their safety and drew back. However, quite a few still remained in the fight as its intensity heightened. Their confidence came from the supreme Emperor experts leading their group. Lin Xun looked around and found most of the fighters to be unfamiliar faces. They probably had entered the Great Thousand Battle Domain from other realm gates. The only ones Lin Xun recognized were Xing Mutian and his group. “Looks like more and more cultivators are entering the Undead Soul Domain from the Ancient Nightmare Battlefield as time passes...” Lin Xun frowned. This meant that the number of opponents vying for Ancestral dao origins would only keep increasing. The trickiest thing was that Ancestral dao origins were impossible to be taken away, and could only be refined on the spot. Even if someone found an Ancestral dao origin first, they still wouldn’t have much time to refine it once an opponent appeared. Just as Lin Xun was pondering, an indifferent and ruthless voice suddenly resounded between heaven and earth, “Get out of the way!” Along with the voice, a group of figures were sweeping in from afar, with their auras displayed in full as they headed straight toward that floating continent. Both the people laying low in the dark and the fighters on the battlefield revealed looks of vigilance and apprehension. This was because the leader of the newly arrived group was one of the Five Absolute Emperors of the Immortal Imperial Wen Clan.
