"What deep-seated grudge exists between Dan Ding Valley and You Di?"
You Di's existence stands as the most insane legendary figure of the Ancient Era.
His deeds, both great and small, are also the most widely circulated. As for whether there are any grievances between You Di and the Thirty-Six Grotto-Heavens or Seventy-Two Blessed Lands, there certainly are. The most famous among these are with Xuan Guan Grotto-Heaven, one of the Thirty-Six Grotto-Heavens, and Ghost Valley Blessed Land, one of the Seventy-Two Blessed Lands.
The grudge with Xuan Guan Grotto-Heaven stemmed from You Di publicly harassing the Xuan Guan Niangniang back then, provoking the entire grotto-heaven to mobilize in full force, leading to a major clash between the two sides.
As for the grudge with Ghost Valley Blessed Land, it was said that You Di once wreaked havoc in the Nine Nether, slaughtering too many ghost-path ancestral patriarchs, inciting the fury of Ghost Valley Blessed Land.
In the minds of Li Xin, Qingqing, and the others, they had never heard of any past grievances or conflicts between You Di and Dan Ding Valley.
"The things You Di did back then were far, far crazier than what the legends say. Although most of those events have already spread, there are a few incidents that did not become widely known, and those who are aware of them are extremely few."
Old Master Kaishan furrowed his brows, his expression grave, as if recalling something. "Dan Ding Valley was nearly wiped out by You Di back then. Did you know that?"
"Such a thing actually happened?"
Li Xin, Qingqing, and the others were utterly shocked. "When did this happen? How come we never heard even a whisper about it?"
"You haven't heard of it because that incident was deliberately concealed by many of the Great Dao Ancestral Patriarchs back then."
"But why? Why would You Di, for no apparent reason, want to slaughter Dan Ding Valley?"
"How to put this matter... You Di himself had no deep-seated hatred with Dan Ding Valley. Not only was there no deep hatred, You Di and Old He from Dan Ding Valley could even be considered friends."
"Old He?" Li Xin asked. "You mean Old Master He of Dan Ding Valley?"
"That's right, it's him."
"Old Master, aren't you and Old Master He friends? I remember you two often went out together in the past."
"Yes, Old He and I were indeed very, very old friends."
"It's been many years since I last saw Old Master He. No! Not just many years—it seems I haven't heard you mention Old Master He at all throughout the Present Era. Is the venerable elder in seclusion?"
"He's dead."
"Dead?" Li Xin exclaimed in shock. "When did he die? How did he die?"
"He committed suicide during the Ancient Era."
"Committed suicide? This... this can't be! What exactly happened? Why would Old Master He commit suicide for no reason?"
"Old He committed suicide to preserve Dan Ding Valley. If Old He hadn't died back then, Dan Ding Valley might truly have been wiped out by You Di."
"Old Master He committed suicide because of You Di? Why is that? What deep-seated grudge existed between You Di and Dan Ding Valley?"
"Sigh!" Old Master Kaishan shook his head slightly, his expression deeply sorrowful. "To speak of the grudge between You Di and Dan Ding Valley, we have to start from a long time ago. The cause was a conflict between a disciple of Dan Ding Valley and a disciple from the Chilian Immortal Realm within Lingluo Celestial Domain."
"Chilian Immortal Realm?" Li Xin pondered. She was relatively familiar with Lingluo Celestial Domain and knew of its various immortal realms, big and small, but this Chilian Immortal Realm was utterly unfamiliar. She had never heard of such an immortal realm within Lingluo Celestial Domain. "Is there a Chilian Immortal Realm in Lingluo Celestial Domain? There isn't, right? I've never heard of it."
"Chilian Immortal Realm was originally just a very small, inconspicuous immortal realm within Lingluo Celestial Domain. However, back when You Di first entered the Great Wilderness, he cultivated there for a period and had good relations with several ancestral patriarchs of Chilian Immortal Realm. In a sense, they could even be considered to have shown him kindness, because when You Di first entered the Great Wilderness, he was judged by the Nine Heaven Immortal Path. Although he underwent Nirvana Rebirth, his physical body was extremely weak, and he recuperated in Chilian for a long time."
"Not many people knew about You Di's seclusion in Chilian Immortal Realm back then, and the disciples of Dan Ding Valley naturally had no idea either. So, that disciple from Dan Ding Valley not only killed many people from Chilian Immortal Realm, but also severely injured several of its ancestral patriarchs. Somehow, this matter later came to You Di's knowledge."
Immortal Li Xin interjected, "So then, to avenge Chilian Immortal Realm, You Di went on a killing spree to Dan Ding Valley?"
"Initially, You Di thought so, and he was prepared to do just that. However, later, after Old He learned of this matter, he personally took the disciple who had acted to Chilian Immortal Realm to apologize and make amends. The several ancestral patriarchs of Chilian Immortal Realm all knew that Dan Ding Valley was not to be trifled with. They did not wish to escalate the matter, nor did they want to implicate You Di because of it, so they accepted the apology, considering the matter settled and defused."
At this point, Old Master Kaishan couldn't help but sigh again. "You have no idea how utterly enraged You Di was when he learned of this. If not for the desperate pleas of Chilian Immortal Realm's several ancestral patriarchs, You Di would probably have slaughtered his way to Dan Ding Valley right then. Those patriarchs managed to persuade You Di with great difficulty, and the matter should have ended there. But who could have imagined..." He paused, then let out another deep sigh. "That disciple from Dan Ding Valley, who had been forced by Old He to kneel and apologize to You Di in Chilian Immortal Realm, returned home fuming with indignation. He gathered a group of disciples and, taking advantage of You Di's absence, went back and killed the several ancestral patriarchs of Chilian Immortal Realm. Not only did they kill the patriarchs, they also left no one else alive in Chilian Immortal Realm, slaughtering everyone cleanly. In the end, they even uprooted Chilian Immortal Realm's origin immortal vein."
"Not many days after Chilian Immortal Realm was annihilated, You Di learned of it. He didn't utter a single word. He simply returned to the Nine Nether, took up a Nine Nether Blade, and directly slaughtered his way to Dan Ding Valley. With one slash, he severed Dan Ding Valley's ancestral monument. From the moment he entered, he killed everyone he saw—men, women, old and young—sparing none. He slaughtered Dan Ding Valley until rivers of blood flowed and corpses littered the ground."
At some point, Old Master Kaishan had closed his eyes, his expression incredibly complex, the muscles at the corner of his mouth twitching uncontrollably. "None of Dan Ding Valley's powerhouses were a match for You Di. Some seniors in seclusion didn't even know what was happening before they were directly cleaved in two by You Di's blade. Even the ancestral tablets enshrined by Dan Ding Valley were reduced to dust and ashes by a single slash from You Di. Even when Dan Ding Valley mobilized its origin and invoked its laws, it could not stop You Di."
"You Di, holding his slaughtering blade, eyes crimson red, was like a human butcher, even more like a demonic god. Knowing they were no match, Dan Ding Valley had no choice but to seek help from the Three Thousand Great Daos. That day, many experts from the Three Thousand Great Daos arrived, among them not a few Great Dao Emperors and even Great Dao Sovereigns. Some intervened to stop him, some spoke to persuade him. Unfortunately, it was utterly useless. Anyone who dared intervene was slaughtered without mercy. Anyone who dared speak a single word of persuasion—if they dared utter even one syllable—You Di would deliver a slash on the spot. He gave no one any face. No one could stop him!"
