East of the Tianhen Continent lay the East Sea.
Further east was the legendary Forbidden Sea.
This sea was filled with powerful lightning, and the spiritual energy was extremely violent.
Crossing this Forbidden Sea would lead to the near shore of another continent.
However, the length of this Forbidden Sea was something many cultivators could not traverse.
Because the area of this sea was simply too vast.
Just its width alone was several hundred thousand sea miles long, its area several times larger than the entire Tianhen Continent.
At this moment, Xu Nian was flying side by side with Xuan Hong.
They had already reached the boundary of the Forbidden Sea.
They were about to enter this Forbidden Sea area that instilled fear in countless cultivators.
Dark clouds blanketed the distant sky.
Lightning flashed and thunder roared.
Numerous Thunder Dragons hung down.
Striking the sea surface.
Turning a patch of sea water into a blue-purple color.
The power of that lightning would kill Holy Level strong men upon contact.
Even Emperor Level strong men dared not easily traverse the airspace above this sea.
"Kid, this Forbidden Sea's lightning is no simple matter, can you withstand it?" Xuan Hong joked as he looked at the lightning ahead.
Xu Nian smiled slightly and said, "Why not!"
With that, he dashed towards the Forbidden Sea.
A bolt of lightning fell directly from the sky, striking Xu Nian's body.
Xu Nian's upper clothes instantly burst apart.
Revealing his pale yet tough skin.
The lightning that struck Xu Nian seemed to be absorbed by his body.
Continuously roaming throughout his entire body.
Hammering every cell in Xu Nian's body.
Among the Divine Demon Refining Body Technique was a Body Refining Technique called Thunder Quenching.
Using the power of lightning to constantly refine the flesh.
Thus making the cells in the body stronger.
"Good boy, the lightning that others fear as a tiger has actually become a tool for cultivation in your case. How could there be such a freak as you among humans? But the deeper you go, the more powerful the lightning will be. You might not be able to withstand it then." Watching Xu Nian fly close to the sea surface, Xuan Hong spoke with a tone that couldn't help but carry a hint of admiration.
Ever since the battle between Xu Nian and the Tianhen Ancestor, Xuan Hong's attitude toward Xu Nian had noticeably changed.
He had to admit, the talent and potential of the young man in front of him were truly terrifying.
Xu Nian did not say much.
Indeed, the battle with the Tianhen Ancestor had brought many gains for him.
Not to mention that the Tianhen Ancestor's dragon veins had been devoured by Xu Nian's dragon veins.
Just talking about the secret technique he used.
Because of the influence of the Earth God Devouring Sky, his Body Cultivation had achieved another breakthrough.
He had officially advanced to the Nine-star Body Emperor Realm.
His Spiritual Cultivation had also reached the peak of the Nine-star War Emperor after taking a few Spirit Pills from the ruins of the Ancient Spiritual Sect.
That is to say, Xu Nian's Cultivation had reached the realm of dual Nine-star Emperor Level.
Only one step away from the Supreme Battle Emperor.
And now Xu Nian was only nineteen years old, he had every hope of reaching the Zifu Realm before the age of twenty.
"Let's go, we'll enter the seabed!"
Before long, Xu Nian dove headfirst into the water, dashing toward the depths of the sea.
At this level of realm, being underwater was no different from being on land.
With his strong body, he could withstand even the deepest sea pressures.
The reason he chose to enter the water was that Xu Nian had once promised an elderly Emperor Scorpion in the desert.
To deliver a small metal box to his friend.
And his good friend was a sea demon living in the forbidden sea region.
His true form was a rare Overlord Sky Splitting Shark!
It was said to reside in a place called the Demon Wind Cave.
As for its cultivation level,
However, according to Xu Nian's guess, it had likely reached the Supreme Battle Emperor Level.
Of course, the Supreme Battle Emperor level also had layers.
A typical Supreme Battle Emperor had levels called Pseudo Purple Mansion, Pseudo Void, Pseudo Harmony, Pseudo Heavenly Phenomenon, and Pseudo Tribulation.
These represented the realms they could have reached.
Yet, they were suppressed by the heavenly laws and restrictions.
Forced to remain in the Supreme Battle Emperor Realm.
As for Pseudo Earth Immortals, they were virtually impossible.
After all, it was impossible to undergo tribulation in this part of the world.
There were hardly any Pseudo Tribulations, except for the Beast God and that person from Dark God Island.
There were a few others like Xuan Hong, who were Pseudo Heavenly Phenomenons.
Although the strength of the Pseudo Heavenly Phenomenon Realm sounded decent, in terms of real power, they were still no match for the true Zifu Cultivators.
This was something Xuan Hong had already confirmed through an encounter with Tianhen Ancestor.
So, no matter how high their realm was, if they were not of the Zifu Realm, they were ultimately still within the Supreme Battle Emperor.
After Xu Nian entered the seabed, he became confused.
The sea region was so vast. Where could he find the Demon Wind Cave?
"I can't go on . I must ask for directions." Xu Nian muttered to himself.
He immediately grabbed an octopus nearby, which had reached the Saint Realm, wanting to inquire about the whereabouts of the Demon Wind Cave.
However, upon hearing the three words "Demon Wind Cave," the octopus fled in sheer panic.
Afterward, he tried a few more times, but the result was the same.
This left Xu Nian confused.
Why did these sea demons flee in fear whenever he mentioned the Demon Wind Cave?
Could it be that the Demon Wind Cave was some formidable power to be feared?
"Kid, it seems your quest for help won't go smoothly. If the sea demons are so wary, it could only mean one of two reasons," Xuan Hong spoke.
"Oh? What are the two reasons?" Xu Nian recalled that Xuan Hong was also a sea demon.
"First, this Demon Wind Cave you're asking about is a very powerful force that terrifies the entire sea region. Clearly, this scenario is highly unlikely," Xuan Hong said.
Although the sea demons had several factions, none dominated over the others.
No one could suppress all.
"Secondly, the Demon Wind Cave you're asking about violated some taboo of the sea region, and someone from this power did something that instilled fear in all sea demons," Xuan Hong spoke again.
He found this second explanation more plausible.
"Swoosh, swoosh, swoosh!"
Just then, a string of splashing sounds came.
A mass of giant fish, sharp as swords, headed towards Xu Nian's direction.
"These are White Patterned Sharks, kid. It seems we've gotten into some trouble," Xuan Hong said with a smile.
"I think they're here to give us some information," Xu Nian replied with a slight smile.
"Swoosh, swoosh, swoosh!"
Dozens of White Patterned Sharks surrounded Xu Nian and the others.
Eventually, all the White Patterned Sharks transformed into human forms, carrying long spears, pointing them at Xu Nian.
Their expressions were fierce and menacing.
A tall and imposing man also stepped out from the crowd.
This man's cultivation was not low; he had already reached the Supreme Battle Emperor Realm.
"So, it's you who are looking for the Demon Wind Cave?" the leading man asked, his voice booming like a bell.
His gaze towards Xu Nian was also extremely unfriendly.
