Having arrived in this Source World many years ago, Lin Yuan had also collected quite a few secret inheritance techniques from the Xuanyin Ancient Kingdom.
Many of the Great Sovereigns from various ancient kingdoms had connections, exchanging goods and information with each other.
Many secret inheritance techniques were naturally part of these exchanges.
However, the secret inheritance techniques that could be exchanged at the Great Sovereign level were still too shallow for Lin Yuan.
Now, these two Heavenly Sovereigns from the Xuanyin Ancient Kingdom gave Lin Yuan hope of accessing the profound secret inheritance techniques of the Xuanyin Ancient Kingdom.
Of course, Lin Yuan didn't expect to obtain the truly forbidden secret techniques of the Xuanyin Ancient Kingdom. Heavenly Sovereigns like Northern Yin Heavenly Sovereign and Extreme Frost Heavenly Sovereign wouldn't record such high-level inheritances, even if they had cultivated them.
But ordinary secret inheritance techniques at the Heavenly Sovereign rank were very likely to be kept as backups.
For example, the Burning Heaven Courtyard founded by Marquis Qingfen contained numerous secret inheritance techniques.
Lin Yuan immediately began to examine the World Secret Treasures left behind by the two Heavenly Sovereigns, which contained Northern Yin Heavenly Sovereign and Extreme Frost Heavenly Sovereign's treasured collections from over the years.
These two Heavenly Sovereigns had no idea that they would be completely stranded in the Black Jade Nest this time.
So, the main combat bodies that infiltrated carried quite a few treasures and rare items.
Lin Yuan's gaze swept over the numerous treasures and rare items, and he directly looked at the secret inheritance technique area.
"《Xuanyin Thirteen Slashes》... This was created by an ultimate Heavenly Sovereign of the Xuanyin Ancient Kingdom, based on the supreme inheritance of the Xuanyin Ancient Kingdom, 《Xuanyin Secret Tome》, condensing ultimate Yin energy into a destructive slash..."
Lin Yuan carefully observed and comprehended.
The so-called ultimate Heavenly Sovereign corresponds to the Supreme Saint in the Chaos Void. Compared to a Supreme Saint, ultimate Heavenly Sovereigns do not rely on their internal universe, but in terms of the path of chaos evolution, they are superior to Supreme Saints.
Each ultimate Heavenly Sovereign of the six great ancient kingdoms, on their chosen path of chaos theory, created their own offensive techniques.
For example, 《Xuanyin Thirteen Slashes》 was created by an ultimate Heavenly Sovereign of the Xuanyin Ancient Kingdom. Each slash was powerful enough to severely wound an ordinary Heavenly Sovereign, and the last few slashes could even kill a normal Heavenly Sovereign.
"Remarkable."
Lin Yuan marveled as he comprehended.
If the path of chaotic power evolution were divided into three levels, then the Chaos Great Saints in the Chaos Void would be at the first level.
Supreme Saints, on the other hand, would be at the second level. As for the ultimate Heavenly Sovereigns of the six great ancient kingdoms in this Source World, they stood at the third level.
The third level of the chaotic evolution path had already condensed its own 'Dao Fruit,' no longer a mere path.
"Unfortunately, the truly profound inheritances of the Xuanyin Ancient Kingdom basically cannot be transmitted." Lin Yuan sighed.
This 《Xuanyin Thirteen Slashes》 was also because it was quite widely circulated among the Heavenly Sovereigns of the Xuanyin Ancient Kingdom, which is why Lin Yuan was able to find copies in the two Heavenly Sovereigns' World Secret Treasures.
"But the gains this time are already great."
Lin Yuan looked at the numerous inherited secret techniques in the World Secret Treasure. There were four other secret techniques at the same level as 《Xuanyin Thirteen Slashes》, and dozens more at the slightly weaker normal Heavenly Sovereign level.
Northern Yin Heavenly Sovereign and Extreme Frost Heavenly Sovereign naturally drew upon the strengths of many schools. To cultivate to the Heavenly Sovereign rank, it was basically impossible to achieve it by working in isolation. They all comprehended countless secret inheritance techniques before finally finding their own path.
"Comprehending these secret inheritance techniques, I clearly feel that my Yin path has become much 'fuller'."
Lin Yuan thought to himself. This fullness was not a fullness of power, but a kind of essential fullness. All along, Lin Yuan's Yang had surpassed his Yin.
Even with the mutual conversion of Yang and Yin, overall, Yin had always been lagging.
"I wonder what kind of great Dao the 《Xuanyin Secret Tome》 of the Xuanyin Ancient Kingdom records?" Lin Yuan felt quite expectant.
The 《Xuanyin Secret Tome》 is the supreme secret tome of the Xuanyin Ancient Kingdom, originating from the Xuanyin Ancestor, analogous to the supreme inheritance of the Liyang Ancient Kingdom.
Xuanyin Ancient Kingdom, Imperial Capital.
In the princely mansions of Northern Yin and Extreme Frost, the true bodies of the two powerhouses opened their eyes.
As Heavenly Sovereigns, as long as they were willing to serve the ancient kingdom, they were basically enfeoffed as princes and possessed a princely mansion in the Imperial Capital.
"That Milky Way actually became a Heavenly Sovereign?" Extreme Frost Heavenly Sovereign still found it hard to believe. The long-standing barrier that core imperial family members of the six great ancient kingdoms could not cross was actually broken by Milky Way.
"Northern Yin..."
Extreme Frost Heavenly Sovereign immediately descended a clone to Northern Yin's princely mansion to discuss the subsequent matters with Northern Yin Heavenly Sovereign.
Inside Northern Yin's princely mansion.
In a pavilion, Northern Yin Heavenly Sovereign sat there, with Extreme Frost Heavenly Sovereign sitting opposite him.
"Northern Yin, what do you say we should do now?"
Extreme Frost Heavenly Sovereign immediately inquired.
Their two Heavenly Sovereigns had secretly acted, but achieved nothing and their main combat bodies were left behind.
"What to do?"
Northern Yin Heavenly Sovereign sighed inwardly. If he had known earlier that Milky Way Heavenly Sovereign was so abnormal, he would never have had ideas about the Black Jade Nest.
He originally thought that Milky Way Great Sovereign taking charge of the Black Jade Nest would weaken this prime treasure land. Unexpectedly, not only did it not weaken, but it became significantly stronger than when Liyang Heavenly Sovereign was in charge.
Liyang Heavenly Sovereign's strength was already close to that of an ultimate Heavenly Sovereign, but his methods leaned towards direct attack, at most severely wounding the two Heavenly Sovereigns.
As for holding them back? He couldn't do it.
However, Lin Yuan's external universe suppression completely restricted the two Heavenly Sovereigns.
In a place like the Black Jade Nest, the ability to restrict was far more important than direct offense.
"There's no other way. We can only report to the Emperor truthfully," Northern Yin Heavenly Sovereign pondered for a while before speaking.
"Report to the Emperor truthfully?" Extreme Frost Heavenly Sovereign fell silent.
This meant they would certainly be punished by the Emperor. Having unilaterally attacked a prime treasure land, breaking the unwritten rules between the two great ancient kingdoms, the Xuanyin Ancient Kingdom, even just for show, would not easily let them off.
"Not reporting, and waiting for the Liyang Ancient Kingdom to pursue us with our personal weapons?"
Northern Yin Heavenly Sovereign glanced at Extreme Frost Heavenly Sovereign.
Although both of them had disintegrated their main combat bodies, their personal weapons remained there.
And in the six great ancient kingdoms, the personal weapons of Heavenly Sovereign-rank powerhouses were highly distinguishable. With their personal weapons, it would be enough to confirm that the two Heavenly Sovereigns had infiltrated the Black Jade Nest.
Not to mention that Northern Yin Heavenly Sovereign and Extreme Frost Heavenly Sovereign displayed their strength within the Black Jade Nest. All it would take is for a Heavenly Sovereign skilled in the Dao of Time to go there, rewind the footage, and they could similarly be exposed.
"We can make a deal with Milky Way Heavenly Sovereign and ask him not to spread the word?" Extreme Frost Heavenly Sovereign pondered for a moment before speaking.
"Deal..." Northern Yin Heavenly Sovereign thought for a moment, "Then let's try."
As of now, only the three of them, Heavenly Sovereigns, knew about this matter. As long as Milky Way Heavenly Sovereign didn't speak, outsiders wouldn't know.
Black Jade Nest.
Lin Yuan was comprehending the spoils he had gained.
Suddenly, he looked up into the distance.
Buzz.
At the border of the two great ancient kingdoms, a clone of Lin Yuan arrived.
In the distance, the clones of Northern Yin Heavenly Sovereign and Extreme Frost Heavenly Sovereign also stood there.
"What do you want?" Lin Yuan casually glanced at the two Heavenly Sovereigns of the Xuanyin Ancient Kingdom.
"Milky Way Heavenly Sovereign." Northern Yin Heavenly Sovereign looked at Lin Yuan. "Can what happened today be concealed?"
"Concealed?" Lin Yuan understood why Northern Yin Heavenly Sovereign wanted him to conceal it. "What can you offer me?"
"As long as Milky Way Heavenly Sovereign conceals today's events, then Extreme Frost and I will owe Milky Way Heavenly Sovereign a favor," Northern Yin Heavenly Sovereign said.
"Yes, we owe you a favor," Extreme Frost Heavenly Sovereign also added.
"Just a favor?" Lin Yuan looked at the two Heavenly Sovereigns.
Stopping two Heavenly Sovereigns from invading the Black Jade Nest and ultimately leaving their main combat bodies behind would also be awarded significant merit in the Liyang Ancient Kingdom.
And with that merit, Lin Yuan could completely exchange for more Liyang inheritance secret techniques in the Liyang Treasure Vault.
"Then what do you want, Milky Way Heavenly Sovereign?" Northern Yin Heavenly Sovereign asked.
"The 《Xuanyin Secret Tome》," Lin Yuan said directly.
"Impossible." Northern Yin Heavenly Sovereign immediately shook his head. "I have already sworn an oath to the Ancestor; it's impossible to transmit this inheritance."
"In that case, you have no value in negotiating with me." Lin Yuan's figure directly vanished.
Making a deal with an enemy Heavenly Sovereign inherently carried risks; it could easily be used by the other party to leverage and threaten later.
If it were a supreme inheritance like the 《Xuanyin Secret Tome》, Lin Yuan wouldn't mind taking a risk.
But it was clear that Northern Yin Heavenly Sovereign and Extreme Frost Heavenly Sovereign simply couldn't produce something that would move Lin Yuan.
So, Lin Yuan was too lazy to continue negotiating and dealing with them.
Liyang Ancient Kingdom Imperial Capital.
Lin Yuan walked out of his princely mansion.
"Slaying the main combat bodies of two enemy Heavenly Sovereigns, according to the merit exchange standards set by the ancient kingdom, each Heavenly Sovereign main combat body is worth 500,000 merit."
"The main combat bodies of two Heavenly Sovereigns amount to 1,000,000 merit."
Lin Yuan calculated in his mind.
One must know that in the previous battlefield between the Qingfen Domain and the Zimeng Domain, Lin Yuan had single-handedly turned the tide, and the merit he ultimately gained was only over 100,000.
"Go."
Lin Yuan naturally wouldn't give up on the merit. He went directly to the Imperial Palace to meet the Ancient Kingdom's Emperor.
Inside the grand hall.
The Emperor of the Liyang Ancient Kingdom looked at Lin Yuan with a slight smile and said, "Milky Way, what can I do for you?"
"The Black Jade Nest I am guarding was infiltrated by two Heavenly Sovereigns from the Xuanyin Ancient Kingdom," Lin Yuan stated truthfully.
"Two Heavenly Sovereigns infiltrated?" The Emperor's expression changed slightly.
The Black Jade of the Black Jade Nest had a great tempering effect on the mental will of Heavenly Sovereign-rank individuals, so it was not surprising that it attracted Heavenly Sovereign-rank powerhouses.
Previously, the Black Jade Nest was guarded by Liyang Heavenly Sovereign. The latter was an experienced Heavenly Sovereign, so enemy Heavenly Sovereigns had no confidence in infiltrating, and thus didn't make significant moves.
"Which two Heavenly Sovereigns were they?" the Emperor inquired.
"Northern Yin and Extreme Frost," Lin Yuan replied.
There were only a limited number of Heavenly Sovereigns in the Xuanyin Ancient Kingdom, so they were easily recognizable.
"It was them..."
The Emperor nodded slightly, "No matter, let this be a lesson. I will publicly issue you a minor punishment, but still allow you to guard the Black Jade Nest."
The Emperor looked at Lin Yuan and said.
The Black Jade Nest nurtured rare Black Jade, and being plundered once was not a huge matter. The Emperor also wanted to use this incident to temper Lin Yuan.
As for the lost Black Jade? Over a long period, it wasn't a severe loss, as the Black Jade Nest was still there and could continuously nurture rare Black Jade.
"Punishment?"
Lin Yuan was slightly startled, immediately realizing that the Emperor might have misunderstood, thinking that he had failed to protect the Black Jade Nest.
"The Black Jade was not plundered by those two Heavenly Sovereigns," Lin Yuan immediately stated.
"It wasn't plundered?"
The Emperor looked at Lin Yuan, frowning.
"Northern Yin and Extreme Frost were left behind by me. The main combat bodies of the two Heavenly Sovereigns should amount to one million merit, correct?"
Lin Yuan looked at the Emperor and said. The distribution of merit involving the Heavenly Sovereign rank had to be approved by the Emperor.
The Emperor of the Liyang Ancient Kingdom was still wondering why the two infiltrating Heavenly Sovereigns didn't plunder the Black Jade, but upon hearing the subsequent explanation, his expression was filled with astonishment as he looked at Lin Yuan.
"What did you say?"
