The Central Heaven Region is located at the intersection of the Eastern Extremity Region, the Southern Gloom Region, the Western Severance Region, and the Northern Cold Region. Like stars surrounding the moon, the power of the four domains converges here, making it the central hub of the entire Domain.
If the Domain is breached by the Sin Beast, the Central Heaven Region will be the final battlefield.
"Young Master, this Central Heaven Region borders the Eastern Extremity Region to the east. Influenced by the purple morning sun of the Eastern Extremity Region, a wisp of morning purple aura appears in the sky every morning, which can help those below the Sovereign Realm improve their comprehension."
"In the south, the Crimson Flame Veins of the Southern Gloom Region extend into the southern part of the Central Heaven Region, making this region hotter than other areas. It produces various fire-attribute spiritual materials, and many alchemists and weapon refiners also reside there."
"The west, due to the intrusion of cold waves from our Western Severance Region, has formed the Frost Corridor, which has nurtured many unique ice-attribute spiritual plants."
"As for the north, the Xuanming Gale of the Northern Cold Region sweeps through, its howling winds resembling the roar of a dragon year-round."
Half a month later, the four of them walked out of the Teleportation Formation and arrived in Central Heaven City in Central Heaven Region. As they walked down the street, Li Tan and the other two introduced the situation of Central Heaven Region to Lin An.
"So, all four directions of the Central Heaven Region are considered forbidden zones. If one's strength is insufficient, it's likely that one won't be able to cross these places to reach the Central Heaven Region," Lin An said.
"What you say is correct, young master. The four sides of this Central Heaven Region were deliberately created as a barrier. Once the Domain is breached and the four domains fall, this barrier can temporarily slow down the invasion speed of the Sin Beast."
Li Tan said, "Of course, the Central Heaven Region is also extremely vast; what I just described only covers the outer edges of the Central Heaven Region."
Lin An nodded, his gaze sweeping over Central Heaven City before him.
Compared to the Western Severance Region, the walls of the Central Heaven Region are even higher, especially the Immortal Rank Heavenly Sword Annihilation Grand Formation that covers the entire Central Heaven Region, which is even more powerful.
It is even more terrifying than the Myriad Stars Heavenly River Overturning Grand Formation in the Western Severance Region.
"Even if I break through to the Immortal Realm, it will be absolutely impossible for me to set up this Heavenly Sword Annihilation Grand Formation," Lin An thought to himself.
As an Immortal array master, he could see even more clearly that the Heavenly Sword Annihilation Grand Formation was not set up by a single Immortal array master, but by at least ten or more.
Although it is Immortal Rank formation, it is probably even more difficult to compare with some top-tier Immortal formations.
"This formation was created by observing the flying swords from outer space. If there's a chance, I might as well go and observe it."
Lin An thought to himself, as for where the flying sword from outer space was, he did have a guess, it was most likely in the Land of Rules.
"Young master, the ancient ruins of Pill Forest Heavenly Stele will not open for about two months. Let's stay here for now."
Soon, Li Tan and the other two led Lin An to a small courtyard, which was one of the Li Clan's properties in the Central Heaven Region.
Lin An nodded. The courtyard didn't look big, but it was surprisingly spacious and well-equipped.
"I have two months left to refine pills," Lin An Anxin said.
He is currently only at the Sovereign Realm Ninth Grade, still some distance from perfection.
Fortunately, he took a lot of resources from the Li Clan this time, which was enough for him to refine the Sovereign Pill.
Reaching the Sovereign Realm Perfection before entering the Pill Forest Heavenly Stele Ruins is definitely not a problem.
That day, Lin An, Li Tan, and the other two strolled around Central Heaven City, experiencing the local customs and culture.
The next day, Lin An went into seclusion, took out materials one by one, and began to refine the Sovereign Pill.
It took Lin An five days to use up all the materials he had and refine ten thousand Sovereign Pill, each of which was equivalent to eight ordinary Sovereign Pill.
"This many Sovereign Pill are enough for me to cultivate to perfection."
Thinking it over, Lin An immediately released the Formation Pattern Lotus Platform, activated the hundredfold flow rate again, and began to frantically refine the Sovereign Pill.
He refined each Sovereign Pill, and his aura gradually increased.
While he was busy cultivating, time passed quickly.
Central Heaven City became increasingly lively.
The Pill Forest Heavenly Stele opens only once every hundred years, making it a grand event for all alchemists, and naturally no one wants to miss it.
If one can gain something from entering the Pill Forest Heavenly Stele, it will be equivalent to decades of cultivation.
Do you think anyone will be able to pass the Fifty-Four Heavenly Steles this time?
"It should be a bit difficult. Last time the Pill Forest Heavenly Stele Ruins opened, I remember that at most, only one person had passed the fiftieth stele."
"You're talking about Senior Ning Shanhai from the Southern Gloom Region, right? He's the one who passed the fiftieth stele back then. I wonder if he's here this time. If he is, there's still a chance to pass the fifty-fourth stele."
"They should come, and I've also heard that Master Xu Ming from the Northern Cold Region is coming, so perhaps there's a chance."
"A hundred years ago, Master Xu Ming was only King Rank, yet he managed to pass through nine Heavenly Steles and subsequently became Sovereign Rank alchemist. Now, a hundred years later, his alchemy skills must be even stronger, not to mention that he is the offspring of Immortal powerhouse."
"Yes, if we can get past the nine Heavenly Steles, then our trip won't have been in vain."
"Having already conquered nine celestial steles, perhaps we should first consider whether we can even pass the initial hurdle, lest we fail to even get through the gate."
The Pill Forest Heavenly Stele Ruins are about to open, and Central Heaven City is becoming even more lively. Even though many people are not alchemists, they still want to join in the fun.
Two figures sat facing each other in a restaurant.
"Fellow Daoist Ning, are you confident about this Pill Forest Heavenly Stele?" Xu Ming asked with a smile, while drinking his wine.
"Passing the fifty-four steles should be no problem, but passing the sixty-three or even seventy-two steles is beyond my capabilities," Ning Shanhai said helplessly.
Among the Pill Forest Heavenly Stele are seventy-two blank Heavenly Steles.
Those who pass the test of the nine celestial steles will receive certain benefits, such as elixir recipes and insights into alchemy.
It is said that as long as one passes the test of the Seventy-Two Heavenly Steles, one will have the opportunity to obtain the Immortal Dao of Alchemy inheritance.
But this is only hearsay; perhaps someone did it in ancient times and the chaotic era, but no one did it in the Abyss of Sin Abyss.
The Age of Sin Abyss has lasted for over three thousand years, Pill Forest Heavenly Stele Ruins open once every hundred years, which means they have opened thirty times already.
Three thousand years is nothing to those in the Sovereign Realm; some have participated more than once.
For example, Ning Shanhai was a powerful figure born in a chaotic era. He participated in the Pill Forest Heavenly Stele competition no less than fifty times, but he only barely passed the 50th stele, which shows how difficult it was.
"With Fellow Daoist Ning's level, passing all the Heavenly Stele tests shouldn't be a problem, but unfortunately there's a time limit," Xu Ming said.
The Pill Forest Heavenly Stele Ruins are only open for one month at a time, so it's not that the trials of the Heavenly Stele are too difficult, but rather that there isn't enough time for them to pass the trials.
If the opening period is extended to one year, Ning Shanhai will definitely be able to pass the test of the Pill Forest Heavenly Stele.
"If Fellow Daoist Xu passes the Seventy-Two Steles of Pill Forest this time, I will come to you for guidance. Please do not refuse," Ning Shanhai said.
"Then I'll take your kind words, fellow Daoist." Xu Ming said, raising his wine cup as well. The two exchanged a smile and then drank it all in one gulp.
