Inside a side hall of the Battle Heaven Pavilion!
Only Lin Heng and Ao Zhantian were seated in the large side hall.
After some casual conversation, Lin Heng took the initiative to ask, "You came with me this time, presumably because of the Fire Clan's last words, right?"
Lin Heng guessed it, but Ao Zhantian showed no surprise. He nodded slightly and then spoke frankly about it.
"Haven't you always been curious about things from Foreign Domain?"
At this Ao Zhantian, Ao Zhantian's expression became extremely solemn, and he slowly recounted the beginning and end of the War of the Foreign Domain.
There is only one race living in this Foreign Domain, which the Nine Heavens call the Hunt Clan.
In Ao Zhantian's words, the Hunt Clan is a race even more disgusting and repulsive than the Big Day.
Years ago, the Hunt Clan accidentally opened a dimensional portal connecting the Nine Heavens. After witnessing the prosperity of the Nine Heavens, the Hunt Clan set their sights on it.
That was the first attack by the Foreign Domain on the Nine Heavens; an army of over a million Hunt Clan stormed into the Nine Heavens.
After arriving in the Nine Heavens, the Hunt Clan killed anyone they saw and plundered countless resources Nine Heavens.
In just one day, taking advantage of the fact that the Nine Heavens experts were unprepared, the Hunt Clan slaughtered hundreds of thousands of cultivators in the Nine Heavens, and even piled up the corpses of these slain cultivators into a high mountain.
Faced with the attack of the Hunt Clan, the Eight Great Imperial Clans and the Ascenders put aside their grudges and united against the common enemy.
After a thousand-year war, the Nine Heavens Allied Forces finally defeated the Hunt Clan and drove them back to the Foreign Domain.
The powerful warriors from the Nine Heavens pursued the enemy all the way into the Foreign Domain, but what they found there was a desolate Foreign Domain with pitifully few resources.
Not only are cultivation resources scarce, but even survival resources are extremely limited.
In the struggle for survival, the weak are eliminated, and their corpses are consumed—this happens every single moment.
Just as the powerful beings of the Nine Heavens were shocked by the sights of this Foreign Domain...
The Foreign Domain ruler begged for mercy and knelt down to plead.
They wouldn't have dared to plot against Nine Heavens unless they were truly desperate to survive.
The Foreign Domain ruler returned all the resources he had plundered and personally killed the powerful figures who had led the expedition to the Nine Heavens.
Ultimately, the Foreign Domain realm promised never to set foot in the Nine Heavens again, and only then did the Nine Heavens powerhouse withdraw from the Foreign Domain.
It wasn't that the Nine Heavens experts were too soft-hearted, but rather that billions of the Hunt Clan lived in the Foreign Domain, and they couldn't possibly kill them all.
In addition, the place was a living hell, littered with corpses, and no one wanted to stay there any longer.
Originally, it was thought that this matter had come to an end, but millions of years later, the Foreign Domain once again forcibly broke through the dimensional passage and invaded the Nine Heavens.
Having rested and recuperated for millions of years, the Hunt Clan was naturally well-prepared. Coupled with the surprise attack, they inflicted terrifying casualties on the Nine Heavens in just one night.
This time, however, the Hunt Clan did not linger in battle. After plundering a large amount of resources overnight, they retreated directly to the Foreign Domain space and sealed off the dimensional portal.
The powerful figures from the Nine Heavens attempted to forcefully break through, but it seemed that several powerful figures were jointly guarding the opening, making it impossible to tear open the dimensional passage.
Having learned from this experience, the Nine Heavens experts immediately dispatched powerful figures to guard the connection points of the dimensional portal, preventing the opponent from breaking through again.
Over the next tens of millions of years, the Foreign Domain made several attempts to break through the dimensional portal, but each time they were blocked by the suppressed Nine Heavens powerhouses.
Just when the higher-ups of Nine Heavens thought they had completely stopped the invasion from Foreign Domain, unexpectedly, a small group of powerful Foreign Domain warriors appeared out of nowhere and once again launched a rampage of looting and slaughter against Nine Heavens before quickly leaving.
After going back and forth several times, they finally found a way to enter the Nine Heavens from another Foreign Domain.
It turns out that they used the power of the small world of Primordial Chaos expert to establish a connection point in the Nine Heavens. However, since the small world was used for teleportation, it was impossible to bring too many people over at once.
Then, those two beings who had transcended the Nine Heavens made their move, erasing the connection point of the small world left behind by the opposing Primordial Chaos expert.
However, the dimensional portal was beyond the control of those two, which became their only way to enter the Nine Heavens.
Since then, every tens of millions of years, the Foreign Domain has opened a dimensional portal and invaded the Nine Heavens again by sacrificing three powerful beings at the Heavenly Firmament Realm, a practice that continues to this day.
After recounting the entire story of the Nine Heavens and the Foreign Domain, Ao Zhantian finally got to the main point. "Although the great war with the Foreign Domain only breaks out once every tens of millions of years, the Foreign Domain can still occasionally send some cultivators of low cultivation levels over through dimensional portals, hoping to plunder resources to take back."
"Low cultivation level? Then even if they come, they'll just be easy prey."
Lin Heng expressed curiosity about this.
Ao Zhantian also provided an explanation: the Foreign Domain possesses a unique supernatural power, which the Nine Heavens call Heavenly Concealment.
Using this divine power, one can become absolutely invisible. Even if the opponent is only a Nirvana Realm cultivator, under the Heavenly Concealment divine power, even Ao Zhantian cannot detect the slightest trace of the opponent.
Fortunately, using this ability comes at a price: the body will be in an extremely vulnerable state, and one will be unable to use their own cultivation.
Lin Heng thought about it and agreed. If there were no restrictions on Heavenly Concealment, and with such absolute invisibility, someone could walk right up to you and strike you directly, who could possibly fight them?
After explaining, Ao Zhantian continued, "Although the dimensional passage is guarded, cultivators below the Primordial Chaos have special methods to come from there. Every so often, the Foreign Domain sends a small team to the Nine Heavens in an attempt to seize resources."
Lin Heng gradually understood from these words: "Could it be that the Fire Clan's last words meant for me to deal with those foreign enemies who secretly came from other Foreign Domain?"
"Good!"
Ao Zhantian nodded in agreement. "Upon reaching the Primordial Realm, all must guard the dimensional passage for 100,000 years."
Upon hearing this, Lin Heng's eyes widened immediately.
"One hundred thousand years?"
Why not use this time to fleece people Nine Heavens instead of staying in that godforsaken place?
Lin Heng naturally refused.
Ten thousand years is enough time for me to fleece every last penny in every corner of the Nine Heavens.
Ao Zhantian then smiled and said, "Although it's said to be 100,000 years, as long as we repel an enemy from another Foreign Domain, we'll immediately change the defenses. It's been over 70,000 years since the last invasion from another Foreign Domain. According to my estimate, they will definitely take action again in at least a hundred years and at most ten thousand years."
That's somewhat more acceptable, but what if I'm unlucky and the Hunt Clan really only comes once every ten thousand years? How much benefit would I miss out on during that time?
Seeing that Lin Heng wanted to refuse, Lin Heng Ao Zhantian silenced him first. "This is a rule jointly set by the Nine Heavens, and no one can be an exception."
Having said all that, Lin Heng understood that even with his silver tongue, he couldn't change the facts.
"Okay! Just let me know when you're coming."
Lin Heng reluctantly agreed.
Ao Zhantian also breathed a sigh of relief. He could give orders to others, but he was really afraid that Lin Heng would be too forceful. Fortunately, Lin Heng did not refuse too forcefully this time.
