"At the very beginning, the door was closed. But alas, humans have curiosity and desires.

What does the world on the other side of the door look like, and are there abundant benefits?

Is it a vast land yet to be developed?

Are there countless ownerless spirit mountains and treasures, or an endless supply of heavenly gifts...

These musings are hard to resist.

Even Venerable Saints are no exception. Mortal Cultivators have their desires, and Saints have their pursuits.

Mortals seek blessed lands and heavenly treasures.

Saints might pursue the Heavenly Dao—the Heavenly Dao on the other side of the door, can it accommodate more of the Great Dao Cultivation?

Can the number of Saints exceed forty-two?

Can the path of the Saints extend farther and stronger?

Thus... it's unclear when it started, but the door was opened."

You Su Yi sighed softly.

"I am merely a few hundred years old, but the era when the door was first opened must have been tens of thousands of years ago.

I only know that when the door was first opened, this world was still in a primitive era, and the people of this world were in a similarly primitive state.

However, in that era, this world had not yet given birth to the civilization of today; it was a vast, virgin land ready to be developed and harvested.

In that era, this world still had many rare beasts now extinct, many rare plants that no longer exist today.

Perhaps, to the Domain Realm, there was some value?

Well, I'm not sure.

But what I do know is, when the door was first opened, people from the Domain Realm poured out and gained some benefits from this world.

Even though the Primordial Qi of this world was scarce, even the most barren land can yield some grain.

Moreover, this land was for free!

So initially, in that era, the Domain Realm must have viewed this world as a target for territorial expansion.

So at the start, they must have gained significant benefits.

But later... changes occurred."

Chen Yan listened, heart shaken, and asked, "What changes?"

You Su Yi took a deep breath and decisively said, "The Heavenly Dao would not permit it!!!"

The Heavenly Dao...

Would not permit it!!

Chen Yan's expression changed.

You Su Yi slowly said, "At the beginning, cultivators from the Domain Realm who came to this world were not suppressed, and many cultivators above the Celestial Human Realm visited here.

In the initial barbaric state of this world, the creatures were utterly unable to resist the plundering and harvesting of resources by the powerful cultivators from the Domain Realm.

But soon, the Heavenly Dao—I mean the Heavenly Dao of this world—reacted, awoke, and used fierce means to deliver heavenly punishment!"

At this point, You Su Yi's tone became cold: "Legends have it that the Heavenly Dao of this world delivered heavenly punishment! Overnight, innumerable thunder tribulations descended upon the vast earth!

Those cultivators daring to open the door and cross realms were reduced to dust under the furious thunder tribulation of the Heavenly Dao of this world!

Their entire cultivation and Primordial Qi were left in this world, and their life essence and immortal bones turned to mud, dissolving into the earth of this world!

Every Primordial Spirit was assimilated by this world's Heavenly Dao.

The details of this monumental change are now unclear in the Domain Realm, but it is said that even Venerable Saints who crossed the boundary perished under the thunder tribulation!

Since then, this world's Heavenly Dao suppresses cultivation, and as soon as any cultivator from the Domain Realm steps into this world, they are suppressed by this world's Heavenly Dao, reducing their cultivation by more than half—the higher the cultivation, the harsher the suppression!"

Chen Yan's face turned pale.

Overnight, innumerable thunder tribulations?

Thunder tribulation isn't ordinary thunder and lightning; it's a tribulation!

A calamity!

The potency is so great...

A little girl at Half-Step Venerable might withstand two or three strikes before she's done for!

A dignified Half-Step Venerable, terrified to the point of fleeing back to the Mirror World, not daring to step outside.

If it's in the tens of thousands, even a cultivator at the Celestial Human Realm might be doomed after just one strike!

"But..." Chen Yan swallowed, still puzzled, "Even if the suppression is severe, even if coming here means losing two or three realms, they're still cultivators; coming here, this world's creatures still can't resist.

Why stop coming and dare not rush over in large numbers?

Is it because they fear the Heavenly Dao here will rain down another thunder tribulation?"

"That's part of the reason, but the more significant reason is, after the Heavenly Dao here delivered the thunder tribulation, exterminating countless trespassing Domain Realm cultivators, problems arose in the other world of the Domain Realm as well.

Numerous spirit mountains and great rivers had their Primordial Qi depleted overnight, many places that once produced heavenly treasures withered overnight.

This incident shook the entire Domain Realm, and many originally powerful sects and clans suffered grave losses due to the depletion of Primordial Qi in their blessed lands, even altering the power distribution in the Domain Realm.

Later, the Celestial Venerable issued a decree, summoning all Saints in the Domain Realm to gather at the Immortal Platform to comprehend the Heavenly Dao.

Nine days later, all the Saints emerged from seclusion, issuing the highest sacred decree in the Domain Realm, thus closing off the Domain Realm. Cultivators from the Domain Realm could no longer freely come and go. Since then, large-scale territorial expansion has been prohibited.

The Saints decreed that the two realms be isolated, and this world cannot be brought within the scope of the Domain Realm's influence."

Hearing this, Chen Yan couldn't help but chuckle coldly.

Understood.

This was the Heavenly Dao of this world settling scores with the Heavenly Dao of the Domain Realm.

The benefits and fortunes taken by your people from my domain, I've come to collect repayment!
