"Spirit Slayer Prison? What is the important matter?" Dan Xuan frowned, he didn't even know about the Spirit Slayer Prison, but it made all the elders of the Holy Tower feel a little surprised.

However, the Nine Operators knew it in his heart, so he was not surprised that Dan Xuan didn't know about the Soul Slaying Prison, and the Nine Operators glanced at the elders below and said, "You guys go down first, this emperor still has something important to say with the alliance leader!"

The elders retreated, but Dan Xuan was a little strange, what was the matter with this so-called Spirit Slaughter Prison, looking at the appearance of the Nine Operators, it seemed to be extremely secretive.

In the Dragon Emperor Palace, only Dan Xuan and Jiu Operator were left, and Jiu Operator explained: "Alliance Leader, you don't know, this year is the decennial Year of the Demon Domain! In fact, it is the ten-year meeting of the Holy Tower to slaughter beast spirits, and the location is naturally the ancient ruins that have been blocked since ancient times, the Spirit Prison. ”

"Hell?" The word Dan Xuan was a little unfamiliar.

Jiu Operator continued to explain: "Yes, it is the Spirit Prison, there must be some hidden history that you don't know, that is, in the ancient flood period, the world was rampant with beast spirits, and at that time the beast spirit clan was the most powerful life form in the world, and human beings were just a vulnerable group that could be slaughtered at will, and it was the beast spirit clan that ruled the whole world at that time! ”

When he said this, Jiu Xuanzi's eyes stared straight at Dan Xuan, as if he wanted to express something through his eyes.

Dan Xuan looked at the eyes of the Nine Operators, and suddenly his heart suddenly changed, and he was shocked: "The powerful race you are talking about is the Heavenly Demon Clan?"

Jiu Operator nodded heavily, and said: "Yes, it is the Heavenly Demon Clan, in fact, they are the most powerful and noble race in the Human Race! However, their fertility is low and their number is too small, and later the restless group led by the Holy Tower began to incite the entire continent, saying that the Heavenly Demon Clan is a foreign race and does not belong to the Human Race, and they also used many despicable means, and the Heavenly Demon Clan at that time was a little caught off guard, and they were taken advantage of by the despicable people of the Holy Tower! At this point, the Heavenly Demon Clan completely declined and even almost extinct!"

Dan Xuan gasped, what the Nine Operators said today was really something he had never known before, he only knew that the Heavenly Demon Clan had ruled the entire continent, but he didn't know what had happened before.

Jiu Operator continued: "The spirit prison I am talking about is actually the sealing array used by the Heavenly Demon Clan to suppress the Beast Spirit Clan back then, and it can actually be said to be a prison!"

"Then, why don't you just end the lives of these beast spirits, why just lock them up?" Dan Xuan was a little puzzled.

Jiu Operator shook his head and said: "Alliance leader, don't you know, the Beast Spirit Clan has an absolute advantage over the Human Race, that is, they can be reborn......

"Rebirth?" Dan Xuan was really shocked this time, the so-called beast spirit he hadn't been in contact with, but he never knew that this race could be reborn!

Jiu Operator nodded slowly, and said: "Yes, although the Beast Spirit Clan has a lower reproductive ability, as long as the Beast Spirit has a strength of level seven or above, it can be immortal, even if it is killed for a short time, it will be reborn after a period of time!"

Dan Xuan gasped, he had never heard of such a strange creature that could be reborn, what a talent this was, no wonder in ancient times, the human race would be completely suppressed by the beast spirit race!

Seeing Dan Xuan Dan Xuan's surprised expression, there was a hint of intriguing on his face, and he suddenly smiled: "Actually, you don't have to be so surprised, the Beast Spirit Race is not the only race on this continent that has the ability to regenerate, there is another race that also has this ability......"

Looking at the gaze projected by the Nine Operators, Dan Xuan suddenly seemed to understand something, and many of the problems that had plagued him in the past seemed to be solved all at once!

"That's right, you're guessing right, the Heavenly Demon Clan also has this ability!" When he said this, Jiu Operator's eyes were awe-inspiring.

The shocked expression on Dan Xuan's face was beyond words, he finally understood why in the Demon Domain, many sealed places suppressed the souls of the Heavenly Demon Clan, but did not destroy them, it turned out that it was not that they could not be destroyed, but that they could be reborn!

Jiu Operator continued: "However, for your Heavenly Demon Clan, the conditions for rebirth are more stringent, I once heard that only the Heavenly Demon Clan, whose strength has reached the level of a saint or above, can obtain the ability to be reborn! But it is only possible, and although they can be reborn with their souls, if they want to become human again, they must have a body that is completely compatible with their souls! This is generally very difficult, so the Heavenly Demon Clan's actual rebirth ability is very limited! Most of the reborn exist in an immortal soul state! Their souls are not like the souls of the human race, which can slowly dissipate with the extension of time! Among the human race, only the souls with great resentment can accumulate resentment and live forever, but they can only become resentful spirits and cannot be reincarnated!"

Jiu Operator spoke slowly, and Dan Xuan felt that the questions that had been haunting his heart all this time had a feeling that they were being solved.

Speaking of this, Jiu Operator's voice paused slightly, but he sighed lightly and continued: " However, for the Heavenly Demon Clan, the ability to be reborn is also the cause of their demise, and the leaders of the Holy Tower 10,000 years ago used this rebirth ability they possessed to confuse the hearing and hearing of all the Terrans, saying that your people are the Beast Spirit Clan and the Terran Race, saying that your body has the blood of the Beast Spirit Clan, so because at this time, the Terran Race completely broke with the Heavenly Demon Clan, and since then, the Heavenly Demon Clan has lost trust, and finally gradually went to extinction! This is a long-ago secret, and there are only a few people in the world who still know this history!"

Dan Xuan became more and more shocked, and the Nine Operators' narration seemed to fill in the blank space of his family's secret history.

Jiu Operator sighed again and said, "So, on the continent today, the human race is the absolute ruler, but many beast spirits and some powerful souls are actually sealed in the forbidden area of many human beings, if it is not impossible to kill at all, why do you think the Holy Tower will not destroy all these aliens?" And the so-called Spirit Prison is the largest beast spirit prison on this continent, although for so many years, the powerful Spirit Hell Array has continuously suppressed the immortal beast spirits in the Spirit Hell Array, but their number is still very large, since about seven thousand years ago, there has been a rule in the Demon Domain, that is, the Spirit Slaughter Prison Conference once every ten years. “
