Chapter 375

Yuding Domain, the central region of the southwest.

There are two great immortal cities here: Yanyang Immortal City and Daguang Immortal City.

However, these two immortal cities are not the protagonists of this region.

The Yan Alliance is the true hegemon of the southwest!

Unlike other great Jin Dan sects in the Yuding Domain, although the Yan Alliance claims to have a heritage, its internal cohesion is not strong.

The reason for this is that the sect was not founded through orthodox sect succession.

It was a rogue cultivator force created by a Jin Dan True Person from another domain back in the day.

As it shone brilliantly during the Opening War four hundred years ago, the prestige of this force grew ever greater.

Especially within that Fenxiang Valley!

That Jin Dan True Person was lucky enough to discover a source-less fire back then—the Wither-Prosper Strange Fire!

With this fire as the core, the force changed its name and took the name Yan Alliance.

Just as the name implies, when the Yan Alliance took root in the Yuding Domain, it absorbed many sect cultivators who had fallen during the Opening War.

Thus, it became an alliance.

And the bond connecting them is undoubtedly the huge profits brought by the weapon-casting business, as well as that Wither-Prosper Fire which involves changes in lifespan.

It is rumored that if a Jin Dan True Person can refine a wisp of this fire into their body, it can increase their lifespan by several decades!

Such a heaven-defying matter naturally makes countless Jin Dan True Persons troubled by insufficient lifespan flock to it.

It is even said that the Yan Alliance, a force similar to a rogue cultivator alliance, was able to establish a sect because they used the Wither-Prosper Fire to befriend the Yuding Sword Sect.

Of course.

Among these rumors, no one knows how much is true and how much is false.

At the very least, it is somewhat like a fantasy that a flame capable of increasing lifespan could be controlled by a great Jin Dan sect.

If it were truly that miraculous, it would have long been forcibly seized by the Sword Sect or even other Nascent Soul supreme sects from outside the domain.

As the war broke out.

The Yan Alliance joined the Sword Sect's side and began to fight externally, and the entire sect became completely busy.

Unlike the timidity of the three allies on the Luoyun Sect side, who were trying to preserve their strength.

The Yan Alliance side was filled with a fanatical atmosphere!

The war between cultivators seems different from the wars in mortal kingdoms, with people flying high and mountains collapsing and the earth cracking.

But in reality, there is not much difference.

It is still an economic account being fought!

And in the war, the greatest loss is none other than relatively low-end weapons like magic tools.

The Yan Alliance is the number one weapon-casting sect in the Yuding Domain!

Relying on this war, they don't know how many spirit stones and resources they have earned.

At the very least, the hundreds of weapon-casting halls in Fenxiang Valley have never stopped.

And the magic tools they sold were not limited to the Sword Sect's side.

Their vassals, the rogue cultivators who followed...

It is even said that they even secretly changed their names and sent people to secretly sell low-end magic tools crazily to the four-sect alliance on the Luoyun Sect side.

In the eyes of the Yan Alliance's high-level officials.

This war should be fought just like this!

As long as it doesn't hurt their foundation, they are willing to accompany them for decades or even a hundred years!

In fact, this is also the reason why Duan Feng's weapon-casting business on the Jinsha Floating Island could not get off the ground at all.

With the Yan Alliance inside and Tianfan City outside, he, Duan Feng, a mere weapon-caster who could only refine high-grade magic tools, couldn't even get a sip of soup.

Some things, Luo Chen and Duan Feng thought too simply.

It wasn't just Duan Feng; other small forces that focused on weapon-casting also didn't get any benefits in this war.

It is even said that their market share was squeezed out quite a bit.

This economic account has always been calculated by someone.

But deep underground in Fenxiang Valley, someone is no longer willing to calculate this account.

"Elder Di, are you coming out of seclusion?"

Deep underground in Fenxiang Valley, which is filled with the scent of strange fireworks all day long, a figure sat cross-legged on a stone pillar with a solemn expression.

Another person walked in from outside and looked up at Di Wanyun on the stone pillar.

The question just now also came from his mouth.

Di Wanyun hung his head low, his expression so gloomy it seemed like water was about to drip out.

"Alliance Master, my son is dead!"

Once these words were spoken, the air instantly became heavy.

After a long while, the Yan Alliance Master slowly said: "Since that is the case, I will not stop you."

Seeing Di Wanyun stand up, he said indifferently: "But you must be clear, you are currently in a period of decay, your strength is greatly discounted, and if you encounter an enemy of the same rank after going out, you will be at the mercy of others."

Di Wanyun smiled coldly, "At worst, I will undo the Wither-Prosper seal. In a life-and-death battle, as long as a late-stage Jin Dan doesn't appear, what do I have to fear!"

Thinking of Di Wanyun's fighting methods.

The Alliance Master nodded.

Indeed, within the seven sects of Yuding, as long as he doesn't encounter a Jin Dan sword cultivator from the Sword Sect or a late-stage Jin Dan great cultivator.

With Di Wanyun's strength, ordinary people really can't do anything to him.

It's just that...

"Undoing the Wither-Prosper seal will cause a backlash of lifespan. With your already limited lifespan, I'm afraid..."

"What does it matter if I die? I was already a person lingering on in a steadily worsening condition." Di Wanyun took a deep breath, his gaze sweeping across the underground, where nearly twenty stone pillars stood tall.

Most of the stone pillars had a cultivator sitting in quiet meditation.

If cultivators from the outside world saw this scene, they would probably find it hard to believe.

In the Yuding Domain, the ones with the most Jin Dan True Persons are none other than the Yuding Sword Sect and Qingdan Valley.

But in the Yan Alliance's Fenxiang Valley, there are actually more than a dozen Jin Dan cultivators!

You must know that on the surface, they still have five active Jin Dan cultivators.

Di Wanyun only retired from the surface in recent years; the outside world just thought he was old and tired of trivial matters.

This power!

Has far exceeded Qingdan Valley.

It is even said that the other four sects are far inferior to the Yan Alliance in terms of the number of Jin Dan cultivators alone.

Including the newly promoted supreme sect, the Luoyun Sect!

After sweeping his gaze over his fellow sect members, Di Wanyun slowly stood up.

"With them here, this Wither-Prosper Great Array will not lack a Jin Dan cultivator like me. Alliance Master, wait for me to return after avenging my son!"

The Yan Alliance Master frowned, "Do you have any certainty of finding the enemy?"

A trace of sorrow flashed in Di Wanyun's eyes.

Then his tone became fierce.

"How could I not find them? My son burned his soul to apply the Wither-Prosper mark on the other party."

Hearing this, the Alliance Master nodded.

Applying the Wither-Prosper mark with the Yan Alliance's bloodline technique.

As long as the other party doesn't quickly flee the Yuding Domain, they will sooner or later be caught by Di Wanyun.

As long as the other party doesn't quickly flee the Yuding Domain, they will sooner or later be caught by Di Wanyun.

"Alright, after you finish your business, come back quickly!"

After saying this, the Alliance Master's gaze fell into the small fire pit at the bottom of the valley, muttering: "With fewer people suppressing it, once the Wither-Prosper fire backlashes, they will all die."

Di Wanyun stopped talking nonsense.

Under the gaze of several awake fellow sect members, he struggled to leave the stone pillar.

After getting off the stone pillar, his whole body seemed to feel much lighter.

Silver-white light flickered on his body, and his figure disappeared from the underground of Fenxiang Valley without a trace.

And with his departure.

In the very center of the twenty huge stone pillars, a weak flame trembled slightly in the fire pit, and the fire grew visibly stronger.

Deep underground.

Luo Chen looked at the double doors in front of him with a strange expression.

The doors were simple and unadorned, without any flowers, birds, insects, or fish, nor were there any ancient seal characters, and even the door plaque that should have been there was nowhere to be seen.

What remained was only the sense of vicissitudes revealed after being polished by time.

What remained were only strange patterns that looked like dragons and snakes, as if they were lightning and thunderbolts.

The two doors were tightly sealed, tightly hiding everything inside.

But what it meant for such a door to appear in the ninth mountain, the most mysterious and dangerous of the Nine Mountains of Accumulated Thunder, was self-evident!

Luo Chen turned around, swallowed, and said in a dry, hoarse voice:

"Brother Wang, have we encountered an ancient cave dwelling?"

"Should be!"

Wang Yuan also looked at the two doors with a fiery expression.

The entire cultivation world knows what an ancient cave dwelling means!

Either it is plain and unremarkable inside, or it contains the entire inheritance and wealth of a high-realm cultivator.

For juniors with low realms, perhaps a single relic could allow them to rise directly.

More powerful relics might even benefit an entire sect.

For example, the Lingkong Secret Realm once controlled by the Yuding Sword Sect!

It is rumored to be the cave dwelling of a Soul Transformation great power. Because of this item, the Yuding Sword Sect changed its decline after the Opening War and quickly consolidated its backbone strength over these years.

And the relic in front of them with a door is undoubtedly an ancient cave dwelling!

"Shall we try?"

Luo Chen released his spiritual sense, and after finding no dangerous aura, he invited Wang Yuan.

The other party nodded and walked up.

The two stretched out their palms and placed them on the doors.

They exerted force together!

With the body-refining realms they had both achieved, a massive force poured out.

However, the doors did not move at all.

"Can't push it open?" Luo Chen frowned slightly, "Formation? Restriction? Mechanism?"

Wang Yuan hesitated, "Shall we try with spiritual power?"

Luo Chen gave a hum.

The two mobilized the spiritual power in their bodies and added it to their palms.

However, the doors still did not move at all.

But!

Crack!

A bolt of lightning suddenly struck down from the nine heavens.

Luo Chen was startled and hurriedly dodged.

Wang Yuan was the same.

Unexpectedly, that bolt of lightning had no interest in them at all, but instead, as if it were extremely spiritual, it struck the stone door.

The two looked over and saw that there were strands of electric light flowing on the doors.

Luo Chen looked back and up, and the thunderclouds that had accumulated for thousands of years above the Trapped Sky Valley were slowly gathering.

His expression changed slightly.

"Go!"

Wang Yuan didn't hesitate and followed behind him, leaving the door area directly.

Arriving outside, Luo Chen looked up at the thunderclouds, his face full of shock and uncertainty.

After a long while, he exhaled a turbid breath.

"I know what the key is."

Wang Yuan also looked up at the strange thunderclouds, "Is it this power of thunder?"

"It should be." Luo Chen nodded, "Perhaps even the formation and origin of the Nine Mountains of Accumulated Thunder are related to the cave dwelling under our feet."

"Then what about us now?" Wang Yuan hesitated, with a bit of hesitation in his eyes.

Luo Chen smiled freely, "Brother Wang, why be so greedy? Staying alive is better than anything else. Not to mention whether we have the means to guide the power of thunder to open the cave door, just the fact that once the door is opened, the Jin Dan cultivators on the battlefield are very likely to discover it."

"At that time, a place like this would not be our turn to get a share of the pie."

Wang Yuan pursed his lips and looked at the double doors with unwillingness.

He had to admit that Luo Chen made sense.

"Let's leave first!"

"This cave dwelling is right here, and no one has discovered it for thousands of years, which shows its mystery; it shouldn't be able to run away."

"When our realms are higher and the war is over, we will come here to explore again quietly."

"Maybe there is even a chance for Nascent Soul or Soul Transformation inside."

This is the best hope.

Wang Yuan no longer opposed it.

Immediately, he and Luo Chen used their means to fill in this place.

Not only that, but even the Trapped Sky Valley outside was filled up.

After everything was done.

Luo Chen swept his sleeves extensively along the range of the previous battle, constantly using the Cleaning Spell to ensure that as little battle aura as possible remained.

Finally, the two left in a hurry.

The location of the Ninth Mountain returned to calm once again.

Except for the black thunderclouds that were constantly accumulating and becoming thicker above the nine heavens!
