Chapter 691: Ancient Mortal Realm Inhabitants

Chu Feng fled, utterly overwhelmed. How could he have sworn brotherhood with him and called him his elder brother? He felt particularly uneasy. What if Yaoyao found out later? He decided to run! He would temporarily stop "bothering" the Corpse Demon and deal with future consequences later.

Piloting the green bamboo boat, he vanished in the blink of an eye, swiftly heading towards the ocean. This flying boat was capable of spatial leaps, having been used by someone to traverse the universe in the past, thus naturally possessing incredible speed.

Soon after, the vast East Sea appeared on the horizon, and Chu Feng made his way towards Immortal Mountain.

"Uncle Ming, where are you? What? You're with some prisoners who escaped from the cosmic black prison, planning something big? Uh, yes, I need to ask you something. I want to know about Yaoyao's grandfather."

Chu Feng felt so guilty and curious that he couldn't hold back. As soon as he entered the East Sea, he couldn't help but contact Uncle Ming in the cosmos to ask about the situation.

Uncle Ming informed him that Yaoyao's grandfather was a legendary figure who had Yaoyao's father late in life. Uncle Ming also explicitly stated that this man was unfathomable. The splendor of the ancient mother planet was largely connected to him; he was its original creator. However, after Yaoyao's father grew up and demonstrated boundless potential, the old man retired prematurely.

"Why?" Chu Feng asked, increasingly curious, especially since even Uncle Ming didn't know the extent of Yaoyao's grandfather's strength.

"This elder pursued something very elusive, unlike the goals of ordinary people," Uncle Ming explained, admitting he hadn't understood it at the time. Of course, he had only heard others mention that Yaoyao's grandfather was constantly pursuing some kind of Yin-Yang balance, putting forward various absurd hypotheses and goals.

Chu Feng, however, gasped. "This... could it be that he wanted to enter the Yang Realm and was accumulating Yang energy in advance?" He had learned through various channels, and was constantly confirming, that the Pilfered Source Breathing Technique had a profound origin, belonging to the Yang Realm and differing from other breathing techniques. Over the years, other breathing techniques had been adapted to suit this universe. According to Young Lady Xi's speculation, incomplete techniques originally from the Yang Realm had been "filled in" with the rules and order of the Yin Realm, effectively transforming them into genuine Netherworld breathing techniques. Based on certain clues, the Pilfered Source Breathing Technique was deduced to be complete, exceptionally powerful, originating from the Yang Realm, unique, and untransformed into a Yin Realm breathing technique.

So, did Yaoyao's grandfather know something? Even his origins were somewhat suspicious.

Upon hearing Chu Feng's conjectures, Uncle Ming also gasped. While it was possible someone had researched the Yang Realm in ancient times, Uncle Ming had never ventured into it and knew nothing about it. It was only in this era that he truly began to engage with it, gradually understanding, especially with the living example of Young Lady Xi by his side.

Now, he looked quite enlightened. "My old master... he really might have been studying the Yang Realm!" he said. He even began to suspect other things. From what was known of ancient times, Yaoyao's grandfather's origins were very mysterious; no one knew his true background.

Chu Feng was stunned and incredibly surprised after hearing all this. Could Yaoyao's grandfather have come from the Yang Realm?

"It's possible," Uncle Ming replied. "The absurd goals my old master set back then were very strange. Now that I think about it, they were related to the Yang Realm. It all makes perfect sense!" Uncle Ming was both excited and helpless, as the ancient era had passed, and nothing remained.

"My old master spoke of fighting his way back, of a true return. This... this was an astonishing heavenly secret all along," Uncle Ming recalled, realizing many clues from ancient legends. Yaoyao's grandfather must have been forced into the Yin Realm against his will, intending to fight his way back.

"The ancient mother planet already had people from the Yang Realm back then. It seems this planet is not simple!"

A myriad of thoughts raced through Chu Feng's mind. The Purgatory Space in Kunlun on Earth contained the City of Light and Death, the Reincarnation Road, and also the abyss, ancient caves, and clay statues of the ultimate land, all leading to rebirth. Earth seemed like a mysterious waypoint!

He also considered that the stone box and the three seeds were discovered in Kunlun. These were precious items that the first generation of true dragons, who had illuminated the heavens billions of years ago in this universe, had pondered and deduced until their dying breath. In that earliest era, eons before the Yin Realm, the stone box and similar items might have already existed, and the universe's most powerful being was searching for them. This was profoundly mysterious.

"Yaoyao's grandfather found the Pilfered Source Breathing Technique and was also the one who spread it," Uncle Ming revealed. It was said that when Yaoyao's grandfather first discovered the Pilfered Source Breathing Technique, he was so overwhelmed with excitement that his emotions spiraled out of control.

"Indeed!" Chu Feng realized, becoming more convinced that both the first generation of true dragons and Yaoyao's grandfather held significant secrets, and it was suspected that none of them were beings native to the Yin Realm.

"Did Yaoyao's grandfather not participate in the ancient war?" Chu Feng asked.

"No, he didn't. It's said he crippled himself through his practice, constantly researching something elusive. Now it appears he wanted to go to the Yang Realm to seek revenge on some invincible individuals, rushing for success. He disappeared a few years before the war even began."

"What?!" Chu Feng exclaimed in shock. Then he sighed, thinking that if Yaoyao's grandfather had been able to participate in the war, the outcome might have been different. Intuitively, he guessed that the person in the coffin at the earth's core was truly extraordinary.

Uncle Ming sighed, "It's a great pity. His achievements were astonishing. Although no one knew the true extent of his power, being able to cultivate Yaoyao's father meant he was undoubtedly extraordinary. Some speculate that he had already 'illuminated the heavens' but used special methods to prevent his Dao fruit from manifesting in the universe."

"What exactly happened to his body?" Chu Feng pressed further.

Uncle Ming explained, "He'd lose control. Sometimes he couldn't restrain himself; his entire body would erupt with blazing symbols, extinguishing his emotions, and he would kill. Now, it seems those blazing symbols were... condensed Yang energy, very similar to the Yang energy on Young Lady Xi."

"So, special symbols formed by condensed Yang energy caused him to lose control sometimes. Was this done to him by someone?" Chu Feng gasped, realizing how incredibly powerful such a person must have been.

"Those incredibly potent Yang energy symbols on his body seemed to have a life of their own. I even heard that divine gold eventually grew from them..." Uncle Ming frowned, recalling the events of that time.

Chu Feng was horrified. He remembered the coffin he had seen at the earth's core, covered in metal chains, with mother gold among them! In fact, the Corpse Demon was also similarly bound by divine gold chains. Could these have grown from his very flesh and blood?

"Uncle Ming, I might have seen Yaoyao's grandfather, under Mount Zijin, in the earth's core directly beneath the mother planet!" Chu Feng explained the situation in detail, then ended the call.

Next, he contacted Young Lady Xi to consult her on some matters.

"Xiao Xi, Xi Xi..."

"If you keep being so sappy, I'll expose you immediately!" Young Lady Xi retorted, feeling goosebumps all over, unable to tolerate his behavior.

"I want to ask you about something from the Yang Realm. Have you ever heard of someone glowing, then symbols appearing on their body, and finally divine gold growing from those symbols?"

Young Lady Xi immediately fell silent. After a long pause, and with Chu Feng's repeated prodding, she finally took a deep breath and asked him very solemnly and seriously, "Where did you hear that from?"

"It seems there was such a person on ancient Earth. Don't interrupt; just tell me quickly," Chu Feng pressed.

"Let me tell you clearly, if this kind of thing is involved, the entities behind it would be absolutely terrifying!" Young Lady Xi stated with extreme seriousness.

"What's going on?!" Chu Feng exclaimed, surprised.

"Because those who can employ such methods on others are the most powerful beings of their respective eras. In the ages they appeared, they were undoubtedly among the select few at the very top of the pyramid."

"Is it really that sinister?" Chu Feng's expression turned serious.

"Of course. Those are supreme figures. They use rules and order to 'plant' mother gold, leaving a speck of gold within a creature's body. As the chosen 'human cauldron' grows stronger, the mother gold also grows, eventually to be harvested for forging weapons. Naturally, a 'cauldron' chosen by such a figure is by no means simple; they are destined to rise in the future. The prerequisite is that they must faithfully cultivate the mother gold, and that the supreme expert ultimately doesn't kill them."

Chu Feng fell silent, processing the information. He was deeply horrified; the waters of the Yang Realm were too deep, even more terrifying than this universe. Could even mother gold be acquired this way?

In that instant, Chu Feng's mind raced. The Pilfered Source Breathing Technique, the stone box, and the three seeds were all suspected to originate from the Yang Realm. Now, Yaoyao's lineage, Young Lady Xi, and even the Land of Reincarnation also seemed potentially connected to the Yang Realm.

He sighed softly. The Yang Realm was terrifying, its depths unfathomable. Having become connected to all these people and items, perhaps one day he would truly have to make a trip to the Yang Realm.

"Will there come a day when I have to leave the Yin Realm and venture into that so-called normal human world?" Chu Feng mused to himself. Influenced by Young Lady Xi, he now referred to this universe as the Yin Realm. Indeed, the more he learned, the more he felt that the universe where Yaoyao resided was, perhaps, the truly normal human world.

Young Lady Xi called out, "Hey, did you hear what I said? I'm telling you, if you encounter someone with a mother gold symbol planted in them, do not attack, do not make contact, and stay as far away as possible. The forces behind them are terrifying; in the Yang Realm, they are legendary divine dynasties and figures that you absolutely cannot provoke."

"Alright, I understand!" After ending the call, Chu Feng pondered for a long time.

"Never mind, there's no use thinking so much now. Let's focus on the present!" Chu Feng thought, resuming his journey. He sped like lightning into the deepest reaches of the East Sea. He then spotted a dense fog and noticed many extraterrestrial evolutionaries besieging the area, blockading the sea, with some even issuing challenges.

His expression was indifferent; he paid them no mind. He quietly concealed himself in the void, then ventured deep into the fog, arriving at the island where Immortal Mountain stood. The twelve force fields he had deployed were still intact, though they had clearly been attacked. Those Holy Sons and others from the outside were indeed formidable; they had launched an assault and landed on the island. Fortunately, the force fields remained incredibly sturdy and had not been breached.

"Brother, you're back!" the Northeast Tiger exclaimed, having been the first to spot him. He had been guarding the island's edge, constantly alert and ready for battle.

"I'm back. Everyone, get ready to evolve!" Chu Feng announced.

"Haha, excellent, I can't wait!" the Great Black Ox roared, expressing his frustration. "Just now, some so-called genius from the demon race landed on the island, bringing a group of people wanting to force their way in. It truly infuriated this old ox! We're trapped here, with them at our doorstep, yet we can't do a thing!" Without the force fields, their situation would surely have been dire.

Chu Feng said, "They finally managed to invite another demon race genius; they were quite swift. But it doesn't matter. Once our group of 'Essence-Consuming' realm cultivators moves out, we'll sweep them away!"
