Su Yuan was momentarily speechless. With a casual wave of his hand, he tossed Xuanyuan Bu'er a Seven Stars Sect Elder Token.

Xuanyuan Bu'er immediately joined the Seven Stars Sect, becoming one of its members. With this, the number of mighty experts in the Seven Stars Sect increased from fifteen to sixteen. The key point was that Xuanyuan Bu'er was a super powerhouse at the peak of the Hunyuan Great Luo Golden Immortal realm, with the potential to reach the Hunyuan Taiji realm in the future.

Su Yuan waited for a moment but noticed Xuanyuan Bu'er hadn't left. Somewhat puzzled, he asked, "Why haven't you left yet? Just activate the token!"

He had left a non-physical Mental Avatar within the token that could activate the [World Traveler] trait. To put it plainly, Su Yuan still needed to be the one to activate it.

Xuanyuan Bu'er stored away the Elder Token and said, "Since I've already obtained the method to leave, there's no hurry to depart! Dao Sovereign, you intend to go inherit the Human Emperor's legacy, right?"

"You guessed it?"

"Yes, I had considered this before. The Human Emperor's legacy should also require inheritance by the Human Race Sovereign. But how could the Human Race Sovereign personally come here to take such risks? If they entered the Primordial Isle, they should have already abdicated the position of [Human Race Sovereign]. This creates a paradox! Unless the Three Realms reach a crisis moment requiring the Human Race Sovereign to personally come deal with the calamity." Xuanyuan Bu'er explained.

Su Yuan nodded: "That's exactly what I think too!"

Xuanyuan Bu'er was actually quite expectant. He had guarded this place for countless years, and the legacy of the Three Sovereigns and Five Emperors had intrigued him for a long time. Now it seemed there was hope to finally see what this legacy actually contained! Perhaps he might even gain some peripheral benefits and possibly break through to the Hunyuan Taiji Great Luo Golden Immortal realm!

This was precisely why he had so readily joined the Seven Stars Sect, fearing that if he delayed, the legacy's benefits might not recognize him as being under the Human Race Sovereign's command and thus not grant him anything, which would be disastrous.

Su Yuan didn't detect Xuanyuan Bu'er's ulterior motives. In his view, since Xuanyuan Bu'er had guarded the Primordial Isle for countless years and remained true to his original intentions even after learning he could leave, his character was truly trustworthy.

He was also very curious about what legacy the Human Race's Human Emperor had left behind.

Under Xuanyuan Bu'er's gaze, Su Yuan arrived at the center of the Great Thousand World and stepped into a mountain peak.

Time and space shifted.

Su Yuan found himself in a corridor.

On both walls were murals.

Rough carvings recorded the path of ancient humanity from birth, development, to prosperity.

It turned out that humanity was originally a naturally-born innate race created by heaven and earth, similar to innate races like dragons and phoenixes, possessing various powerful innate talents.

Later, the first Human Emperor, to expand humanity's population, weakened the bloodline power of descendant humans. Humanity's bloodline grew progressively weaker, but their numbers increased dramatically. Eventually, humanity became the race with the largest population among the Three Realms!

"So that's how it is. Humanity didn't start with a weak bloodline - they actively weakened it themselves!"

Su Yuan suddenly understood. No wonder the number of mighty experts among humanity wasn't inferior to other innate races. This bloodline weakening would gradually reverse through ancestral reversion as cultivation realms increased, thereby enhancing potential!

The True Dragon Clan had learned from humanity's approach, though instead of weakening their bloodline, they spread it among the Myriad Races, then converted the most elite parts into members of the Dragon Clan itself!

Other races had similar methods to varying degrees, but only humanity was most thorough, weakening their bloodline all the way to mortal level, to the point where even finding a mortal with spiritual roots to cultivate was difficult.

However, the murals also mentioned that when humanity's population expanded to a certain extent, they could begin gradually increasing their bloodline concentration. If this process were completed, humanity would completely dominate the primary position in the Realm Sea, and other races would inevitably become vassals or even face extinction!

"What an enormous plan!" Su Yuan exclaimed in admiration.

Faintly, Su Yuan understood why humanity later encountered great calamities. Clearly, humanity's scheme might have been discovered by the Myriad Races, who then overthrew humanity's high-end power.

"But why did the Three Sovereigns and Five Emperors leave the Immortal-Demon Realm Sea before completing this plan?"

Su Yuan felt another wave of confusion.

When he passed through the corridor, he entered a palace.

A translucent figure stood with hands behind its back, facing away from him, staring intently at the ceiling above.

Su Yuan glanced at the ceiling but saw nothing there.

"You've come?" the translucent figure spoke.

Su Yuan nodded: "I've come."

"You shouldn't have come!" the translucent figure shook its head.

Su Yuan's mouth twitched: "But I came anyway."

The translucent figure withdrew its gaze from the ceiling and looked at Su Yuan: "You've become the Human Race Sovereign while only at the early Hunyuan Great Luo stage. It seems humanity has truly declined!"

Su Yuan was surprised: "You can't see what's happening outside?"

"Naturally. This is merely a remnant thought I left here."

The translucent figure shook its head, "I forgot to introduce myself. I am the Green Emperor, one of the Five Emperors."

Su Yuan understood: "So it's the Green Emperor. I am the Seven Stars."

"Yes, I am the last emperor. The legacy I left here contains the Wood Dao inheritance and the Life Dao inheritance, along with a puppet possessing the strength of a Hunyuan Taiji Great Luo Golden Immortal. Originally intended to deal with humanity's calamities, judging by your leisurely state upon entering, this clearly isn't a crisis moment." The Green Emperor shook his head.

Su Yuan raised an eyebrow: "On the contrary, humanity has reached a critical juncture. I just have a relatively good mindset!"

"Tell me about it," the Green Emperor requested.

Su Yuan then described humanity's current state and the secret schemes of the Lord of the Demon Realm and the Lord of the Immortal Realm.

After hearing this, the Green Emperor nodded slightly: "So that's how it is. That is indeed quite dangerous."

"Go to the back hall to retrieve it!" The Green Emperor waved his hand.

"No tests required?" Su Yuan asked in surprise.

"Tests? You are the [Human Race Sovereign]. The human destiny concentrated upon you is extremely solid - over ninety-nine percent of humanity acknowledges you, far more than during my time. What would I need to test you for?" The Green Emperor chuckled wryly.

Su Yuan understood. Earlier, when he used the Big Dipper to bestow blessings, he had essentially won over all human beings at once. If not grateful, at least they wouldn't oppose him becoming the Human Race Sovereign.

So although his attainment of the [Human Race Sovereign] position was somewhat coincidental, it was indeed highly recognized.

Su Yuan bowed respectfully toward the Green Emperor: "Then I'll help myself!"

The Green Emperor sighed: "Unfortunately, that puppet only has one battle's worth of power. If you use it once, it won't be useful afterward. Use it carefully - don't think having a puppet means everything is solved! Your strength is indeed too weak."

Su Yuan said helplessly: "Green Emperor, I'm only weak on the surface!"

"Oh?" The Green Emperor raised an eyebrow.

Su Yuan threw a punch, condensing the power of the [Tear of Eternity] into his fist, unleashing force comparable to a peak Hunyuan Great Luo expert.

"Oh?" The Green Emperor expressed surprise, "Quite interesting. Is this the power of some supreme treasure?"

Su Yuan nodded: "Indeed it is."

The Green Emperor waved his hand: "Don't rely solely on external forces. The most important thing is your own Great Dao!"

Su Yuan then asked: "Might I ask where you all went after leaving the Realm Sea? Why did you leave? And when will you return?"

The Green Emperor sighed: "We originally established the Primordial Isle thinking we could survive every Kalpa. But after completing it, we discovered that beyond Kalpas exist Immeasurable Kalpas. That's when we realized the Realm Sea isn't eternal either. So we journeyed together beyond the Realm Sea to seek the path to eternity!"

"Where we went, even I don't know. I'm just a remnant thought of the Green Emperor with fragmented memories. I don't know where they went - perhaps they themselves don't know either. I cannot contact them. Once you inherit the legacy, this remnant thought of mine will dissipate." The Green Emperor sighed.

But soon, the Green Emperor's tone brightened: "However, since I still exist, it proves my original self is still alive! Hahaha, I look forward to meeting you someday in the future!"

Hearing this, Su Yuan had an idea and asked: "After you dissipate, will this remnant thought return to your original self?"

The Green Emperor first shook his head, then nodded: "If I maintained my previous realm and strength, it should be impossible. But if I achieve a breakthrough while in the chaos, perhaps it can be done!"

Su Yuan understood: "I see!"

"Go now. Take my inheritance and leave. Come for the subsequent inheritances when humanity faces true danger!" The Green Emperor said.

Su Yuan was speechless. Was he just giving him this opportunity? How stingy!

The Green Emperor seemed to hear his thoughts and laughed: "With the protection of the Human Sacred Mountain, mere Demon Lord and Immortal Lord cannot cause devastating damage to humanity unless they reach the Wuji realm. Rest assured!"

Su Yuan composed himself and stepped into the back hall.

Three light clusters remained here: the Wood Great Dao inheritance, the Life Great Dao inheritance, and a puppet!

Su Yuan casually collected them, and the three inheritances fell into his hands.

Simultaneously, the Green Emperor's remnant thought dissipated completely.

Su Yuan glanced back in the direction where the Green Emperor's remnant thought had been, thinking to himself: "If the Green Emperor's original self can reclaim remnant thoughts, then meeting your original self would be much easier for me!"

Su Yuan immediately began absorbing the two major inheritances.

Countless knowledge poured into Su Yuan's mind, with vast and profound Daoist techniques flooding in instantly.

The inheritance encompassed everything, covering countless Daoist techniques. Among them, Su Yuan even saw alchemy inheritance that could refine pills up to the Hunyuan Taiji Great Luo level, far surpassing the profundity of the Shangqing Sect's techniques!

Or rather, the Shangqing Sect's inheritance was merely a partial introductory portion of this complete inheritance.

Of course, there was also the Green Emperor's most proud puppet technique, which could actually create puppets at the Hunyuan Taiji Great Luo Golden Immortal realm!

Incredible.

Su Yuan spent a full three days and nights just organizing the catalog. Comprehending all this content would require enormous amounts of time.

Then he looked at the Hunyuan Taiji Great Luo puppet. This puppet only had power for one battle.

But there was a question: if he stored it within the [Tear of Eternity], could it be reused?
