This aura of the Sovereign Realm was extremely faint, so faint that Lin An almost didn't notice it.
Lin An sent out his divine sense, following the wisp of aura, but quickly stopped.
Then Lin An waved his hand and disappeared from the spot with the Heavenly Spirit Emperor. When they reappeared, they were already in front of a portal.
The aura of the Sovereign Realm emanated from here.
"Where is this place?" Lin An asked.
"Reporting to Senior, this is the entrance to the Rules Secret Realm of my Heavenly Spirit Empire."
As he spoke, Heavenly Spirit Emperor took out a jade seal and opened the entrance directly.
"It's definitely in here."
Lin An narrowed his eyes. As the entrance opened, the aura of the Sovereign Realm intensified.
He then walked inside with the Heavenly Spirit Emperor.
Although it is a portal, it is actually more like a Teleportation Formation.
When Lin An landed again, he found that he had indeed arrived at a secret realm located in the void.
Compared to the outside world, the rules of heaven and earth in this Rules Secret Realm, though not as rich as those in the Land of Rules, are still a hundred times more concentrated.
No wonder every emperor could reach the King Realm Ninth Grade in the shortest possible time.
However, although the rules of heaven and earth in the Rules Secret Realm are rich, there is still a huge gap between it and the Land of Rules, which is not enough to support the King Realm Ninth Grade to break through to the Sovereign Realm.
"It is said that this Rules Secret Realm was formed from a Spirit Realm after your ancestors entered the Land of Rules. All three great empires have such a Rules Secret Realm," Lin An said.
"That is indeed the rumor, but I don't know the specifics," Heavenly Spirit Emperor said helplessly.
There are simply too few records about the royal family's ancestors, and there are many things that the royal family doesn't know, yet there are inexplicably many rumors circulating outside.
Lin An remained silent; he knew the rumor was probably true.
As a powerful being at the Sovereign Realm, he could use certain methods to gather a large amount of the rules of heaven and earth, and thus create Rules Secret Realm.
However, this artificially created Rules Secret Realm can only support cultivation at the King Realm; don't even think about breaking through to the Sovereign Realm.
A few breaths later, Lin An's eyes flickered, and he led the Heavenly Spirit Emperor to the central area of the secret realm.
There is a stone platform here, and on it is a futon.
"Senior, this is where I often cultivate," Heavenly Spirit Emperor hurriedly explained.
Lin An waved his hand without speaking, but his divine sense had already spread out.
The Heavenly Spirit Emperor looked at the stone platform with curiosity, finding it spotless and unremarkable.
After a while.
"So that's how it is. The passage was right here," Lin An said with a smile.
Just now, his divine sense spread out, and following that wisp of the Sovereign Realm aura, he indeed discovered a passage.
This wisp of aura was likely left behind by the founding emperor of the Heavenly Spirit Empire, so that future generations could use it to guide them through the passage.
The only thing that Lin An found regrettable was that the passage had been destroyed.
This stone platform in front of us must have had an array that opened the passage, but someone destroyed it, and the passage was destroyed along with it due to spatial disorder.
Of course, if he wanted to, he could re-organize the passageway, but that would take a long time.
He estimates it will take at least one or two years to get a general idea out of it.
"But at least we've found a way. I imagine there's a passage like this within the Rules Secret Realm of the Heavenly Revelation Empire and the Heavenly Star Empire," Lin An thought to himself.
Although it will take one or two years to sort things out, it's still acceptable for him. There's really no other way, so this is the only option.
"Senior, you just mentioned a passage? What kind of passage is there?" The Heavenly Spirit Emperor had a guess in his mind and couldn't help but ask.
Lin An didn't hide anything and explained the situation to the other party, since it wouldn't matter even if they knew.
Upon learning that there was a passage within the Rules Secret Realm, and that the other end of the passage might lead to an even more powerful world with the opportunity to break through to the Sovereign Realm, it would be a lie to say that the Heavenly Spirit Emperor was not excited.
Then, as if realizing something, Heavenly Spirit Emperor shouted, "It was Emperor Taizong! It was Emperor Taizong who destroyed this passage!"
"Emperor Taizong?" Lin An asked in surprise.
"That's right. It's said that during the reign of Emperor Taizong, the Rules Secret Realm experienced an explosion, but the Rules Secret Realm wasn't damaged, and no one paid any attention to it afterward."
Heavenly Spirit Emperor said, "But now that I think about it, it's very likely that Emperor Taizong himself destroyed the passage."
"Why would he destroy it? Did he think five hundred years of lifespan would be enough?" Lin An asked curiously.
Heavenly Spirit Emperor's expression froze. Five hundred years of lifespan was far from enough. Let alone five hundred, even a thousand or ten thousand years would not be enough for an emperor.
"It is said that the explosion occurred in the fifth year after Emperor Taizong ascended the throne, perhaps because he thought he could still live."
Heavenly Spirit Emperor said helplessly, "It all happened three thousand years ago. He has no idea why Emperor Taizong destroyed the passage."
"Senior, can this passage be repaired?" Heavenly Spirit Emperor asked.
His lifespan was nearing its end. He had no choice before, but things were different now. If he could repair the passage, he would have a chance to break through to the Sovereign Realm.
Life expectancy might increase then, and people won't die young.
"Don't even think about it. I know your Heavenly Spirit Empire King Rank array masters, but even for King Rank array master, it would take at least several hundred years to repair, and there's no guarantee of success."
Lin An shook his head. The passage was destroyed too thoroughly; otherwise, even with his strength at the Sovereign Realm, it wouldn't have taken him one or two years to repair it.
" King Rank Array Master?"
As Heavenly Spirit Emperor spoke, his expression changed. "Senior, Heavenly Revelation Emperor came to my Heavenly Spirit Empire recently specifically to borrow King Rank array master. Could it be that he already knew about the passage?"
It's no wonder he didn't think much of it. Some time ago, the Heavenly Revelation Emperor suddenly arrived and offered him resources that were hard for him to refuse. All he had to do was send their King Rank array masters to the Heavenly Revelation Empire for five years.
Although these resources are indeed of no use to him, they can help the Heavenly Spirit Empire cultivate several more King Realm experts. Even if he dies of old age, it will benefit future generations.
At the time, he wondered why the Heavenly Revelation Emperor would do this, and thought that some important formation of the Heavenly Revelation Empire had been destroyed, so he agreed.
But hearing Lin An say this now, he couldn't help but think more deeply.
"Oh? Is that so?"
Lin An was pleasantly surprised to hear this.
If Heavenly Revelation Emperor truly mobilized King Rank array master to repair the passage, it indicates that the passage within the Heavenly Revelation Empire was not severely damaged.
This will save him a lot of time.
After chatting with the Heavenly Spirit Emperor for a few more minutes, Lin An left the Heavenly Spirit Empire. He had learned everything he could.
"Don't rush back to the Heavenly Revelation Empire. Let's go check out the Heavenly Star Empire first; we might find some other clues."
With that thought in mind, Lin An also headed towards the Heavenly Star Empire.
