Having reached this point, Lei Dong calmly answered the Butterfly Emperor's question: "Whether or not I am a Chosen One, I cannot say, but my comprehension of the Law of Annihilation does not come from myself. Instead, it is inherited from a predecessor named Demon Emperor Yan Chixing. It is not that I am trying to ride on someone’s coattails; I can be considered a succeeding-generation disciple of the Demon Emperor, because the majority of my inheritance comes from him."

"What? You are actually a succeeding-generation disciple of the Demon Emperor?" Tai Ming and the Butterfly Emperor were both exceptionally surprised, their faces filled with shock.

Never mind them. Even Fairy Canglan and the Queen of Suffering exchanged glances, secretly thinking their Master's origins were indeed extraordinary. Although the Demon Emperor and the Underworld King were figures of equal renown, one had perished in ancient times, long before they were born. The other had stirred up immense turmoil in the Three Realms tens of thousands of years ago, striking terror into the hearts of the mighty ones therein.

Though the two of them hadn't experienced those events firsthand, they had heard about them countless times. The most widely discussed incident was when the Demon Emperor killed one of the Ten Peak Masters, the Asura-level Old Ancestor of the Blood River, with a single gesture.

Before this, they had naturally assumed Lei Dong was a succeeding-generation disciple of the Underworld King. They hadn't anticipated the inheritance of the Demon Emperor being involved as well.

"Seniors, do you have some history with the Demon Emperor?" Lei Dong was slightly surprised as well. This was the Savage World; these barbarians should have little connection to the Demon Emperor, right?

As if sensing Lei Dong's thoughts, the Butterfly Emperor spoke with a grave expression: "Though we reside in the Savage Lands, we have heard the great name of the Demon Emperor too often. Originally, our Great Ancestral God intended to meet the Demon Emperor. Unfortunately, before the Savage Ancestor could make his move, the Demon Emperor perished under the siege of the Supreme Beings of the Three Realms."

"That's right. Our Ancestral God also inquired about some of the Demon Emperor Yan Chixing's origins. He deduced that the Demon Emperor should be related to the inheritance of the Underworld King. Unfortunately, the Demon Emperor deliberately suppressed his strength back then, and once his identity was revealed, he died too quickly. Our Ancestral God could not confirm it truly." Tai Ming’s face was also extremely solemn: "Our Ancestral God once said that the Demon Emperor was most likely a succeeding-generation successor of Lord Underworld King. It's a pity that the Demon Emperor deliberately suppressed his strength before, and once his identity was exposed, he died too fast. Our Ancestral God couldn't truly verify it."

"I can confirm this point; the origin of Senior Demon Emperor is indeed the Underworld King's subsequent move," Lei Dong nodded in confirmation.

"You can confirm that? Then, in that case, your identity has some connection with our Ancestral God," Tai Ming expressed slight surprise.

Lei Dong was somewhat speechless about this. He shouldn't have any connection with that Savage Ancestor; they were beings from completely different worlds.

"Perhaps you don't understand, but if I invite the Ancestral God to visit, you will understand," Tai Ming said without further argument. He began to emanate overwhelmingly powerful divine thought, produced a circular spiritual treasure, closed his eyes, and chanted incessantly.

A short while later, Tai Ming’s massive frame shook, and the aura around him instantly underwent a drastic transformation. That aura, while gentle, revealed an incomparably mighty majesty.

What shocked Lei Dong greatly was that the aura felt vaguely familiar to him.

"Welcome, Great Ancestral God." Seeing this, the Butterfly Emperor hurriedly bowed first. The other Butterfly People and the Underworld Giants also swiftly paid their respects from mid-air.

A majestic, discerning gaze swept towards Lei Dong. Just this single glance gave Lei Dong an uncomfortable sensation of being completely seen through. He wanted to resist, but facing that terrifying and suppressive aura, he dared not even move a finger.

It wasn't just Lei Dong; Fairy Canglan and the Queen of Suffering trembled as if they had witnessed the most dreadful thing in the world.

"Child, do not fear me. I am the Ancestral God, and the Butterfly People and Underworld Giants are races I created. They are not the only ones I created. But now, after endless wars, my children have died one by one, leaving only a small number of Underworld Giants and Butterfly People still fighting the allied forces of the Three Realms." The dominant consciousness speaking through "Tai Ming" had clearly changed. The voice spoke with gentle kindness: "Tai Ming has transmitted to me what just happened. Child, first, thank you for helping my children."

Indeed, it was the Ancestral God of the Barbarians. Lei Dong became excited in his heart. Although this was likely some form of consciousness projection, this was truly the first time in his life he had encountered a Supreme-level powerhouse.

This honor was not something anyone could possess. Immediately, Lei Dong hurriedly cupped his hands and said, "Junior Lei Dong pays his respects to Senior Ancestral God."

"It is reasonable for you to call me Senior. Based on what we have confirmed together, Demon Emperor Yan Chixing is a succeeding-generation disciple of Underworld King Xiudisi, and Xiudisi, in turn, is my succeeding-generation disciple. Tell me, doesn't this mean we have some connection?"

Ah? Lei Dong was truly stunned; the most astonishing event of his life was happening right now. His eyes widened, and he stammered: "Sen-Senior, are you... Underworld God, Senior Underworld God?"

"That's right, I did once use the name Underworld God. Unfortunately, some of my schemes were discovered by the Demon Venerable. And the Demon Venerable also deemed me a Chosen One. So, he gathered the Immortal Venerable and the Mother of All Spirits to besiege me," the Underworld God sighed. "Fortunately, I escaped quickly, leading the three Venerables to mistakenly believe I had already died. I finally fled to this Savage World. After recuperating and recovering my strength, I began nurturing some powerful races, resulting in the Underworld Giants and Butterfly People, preparing for a counterattack when the need arose. Regrettably, hundreds of thousands of years ago, the Demon Race's reconnaissance troops discovered the situation here."

"I used some special means to deceive them, making them think I was also a powerhouse who had passed the Great Tribulation of Samsara. Because of this, they lowered their guard against me, only dispatching powerful subordinates to attack me," the Underworld God lamented. "The allied forces of the Three Races are indeed formidable; even I have suffered heavy losses in repeated battles."

"What? Even an existence as powerful as you suffered losses at the hands of mere minions?" Lei Dong was astonished again. In his imagination, the Underworld God, the Underworld King, the Demon Emperor, and the Supreme Beings of the Three Realms were all incomparably mighty figures. If they attacked each other, perhaps there would be casualties. How could the Underworld God be injured by a mere group of underlings?

"Child, do not underestimate the Immortal, Demon, and Monster Races; they are the descendants painstakingly birthed by the Three Great Supreme Beings," the Underworld God sighed, saying, "Individually, they are not terrifying, but when gathered as an army, even I must retreat three steps. The Supreme Beings are merely the current strongest existences; they do not possess immortal and unkillable bodies! How could they possibly not be wounded? Moreover, in the ancient war, I was wounded by the Supreme Beings of the Three Realms, injuring the very root of my life essence. I have never truly recovered."

Lei Dong was moved and said, "How can you be healed? Is the Chaos Origin capable of doing that?" His heart was also stirring. If the Chaos Origin could heal the Underworld God, then he would heal him no matter the cost. This was not just his inheritance; the true origin should ultimately be the Underworld God. The Underworld God was the greatest progenitor.

Most importantly, the Underworld God was a Supreme-level powerhouse and his natural ally. If he had the help of a Supreme-level expert in the future against the Mother of All Spirits, the chance of success would greatly increase.

Even though Lei Dong was supremely confident in himself, he dared not claim that he could advance to the Supreme level within ten thousand years. Even an existence like the Demon Emperor took millions, perhaps tens of millions of years, to gradually grow.

"Child, I understand your thoughts." After confirming Lei Dong's inheritance and identity, the Underworld God spoke with exceptional tenderness and affection. Theoretically, Lei Dong was his only surviving grand-disciple in this lifetime. But there was an indescribable weariness in his voice: "Unfortunately, hundreds of millions of years ago, I was already wounded at the fundamental level by the Supreme Beings of the Three Realms. If it weren't for my immensely powerful life force, I would have perished completely long ago. Now, I am barely clinging to existence, ready to dissipate at any moment. Fortunately, the great Will of the Universe took pity and sent you to my presence. Seeing you, I see hope for the future. I just scanned you—the True Essence within your body, is it Chaos True Essence? When I first conceived the Chaos Art, it was only a nascent form, which I passed down using special methods. I never expected that Xiudisi and Yan Chixing, those two children, would be so brilliantly intelligent as to truly perfect my Chaos Art. Furthermore, child, you are also formidable. Looking at your bone age, you seem very young, yet your cultivation is already extraordinary. My future depends on you to help realize it."

"Thank you for the praise, Ancestor. Junior only inherited the grace of my predecessors to achieve the strength I possess today," Lei Dong said respectfully and humbly. "As for you, Ancestor, you not only founded a school of thought but also created so many powerful races."

"What I did were merely trivial tricks, not the Great Dao," the Underworld God chuckled. "Otherwise, I wouldn't even be unable to deal with some of the lackeys of the Supreme Beings of the Three Realms. Child, I hope you can truly inherit my legacy and help me eliminate the Three Great Supreme Beings? And bring fairness back to this universe? You must understand, figures like the Three Great Supreme Beings, if given another chance after passing the Great Tribulation of Samsara, will become even more formidable, impossible for anyone to oppose."

Lei Dong thought about it carefully, then slowly shook his head and said, "Ancestor, I cannot promise you that. Currently, I do not wish to clash with the Immortal Venerable or the Demon Venerable. My only enemy is the Mother of All Spirits. If they do not provoke me, I will not provoke them. So, Ancestor, I do not wish to deceive you."

"Very good. You can maintain your nature even in the face of immense profit, which makes me feel very gratified. You will walk further and further on the path of cultivation in the future." The Underworld God was not angry; instead, he offered praise.
