Chapter 1357

"Sign in."

Jun Xiaoyao thought silently.

"Congratulations to the host, ten-star sign-in reward: one Main Sacrifice Token!"

As the system's voice fell.

A pitch-black token appeared before Jun Xiaoyao.

This pitch-black token was incomparably ancient, neither gold nor wood, neither stone nor jade; one couldn't tell what material it was made of.

It emitted an extremely ancient aura.

On the token, a number "five" was carved in ancient primeval script.

The reason Jun Xiaoyao recognized primeval script was because the Jun Clan's Scripture Library contained many primeval script classics.

Looking at this so-called Main Sacrifice Token, Jun Xiaoyao inexplicably felt a wave of palpitations.

This pitch-black Main Sacrifice Token did not emit any special fluctuations.

Not to mention Imperial weapons, even the aura of a Supreme weapon seemed to be countless times stronger than this Main Sacrifice Token.

But Jun Xiaoyao always had a feeling of his heart trembling slightly.

With his mental fortitude, for him to have this feeling, one could imagine just how mysterious this Main Sacrifice Token was.

Jun Xiaoyao seemed to see that this Main Sacrifice Token was stained with the blood of countless beings.

And just as Jun Xiaoyao signed in for the Main Sacrifice Token.

The entire Nine Heavens seemed to be surrounded by a faint aura.

Within one of the Ten Great Forbidden Zones, the Ruins of the Holy Spirit, an ancient existence was startled.

"Eh, that aura, could it be..."

In another forbidden zone, the Immortal Mausoleum, a supreme existence was similarly surprised.

"It really is that aura. It seems this 'Great Cleansing' will be the most terrifying in history."

In one of the Ten Great Forbidden Zones, the Emperor-Falling Shenshan, a strong person was also speaking coldly.

"A long time ago, after that one in the Sea of Reincarnation was heavily injured by Wuzhong and fell into a deep sleep, that position had been vacant."

"Now, is there finally a successor? I wonder which forbidden zone's supreme existence it is; let me try to deduce it."

However, after some calculation, this supreme being of the Emperor-Falling Shenshan revealed an unprecedented look of shock and doubt.

"It cannot be deduced. It seems it really is a certain Forbidden Zone Master who has shielded the karma, making it impossible for others to spy on. Forget it, better not offend them."

"It seems this Main Sacrifice Ceremony will create history. Perhaps someone really can step in there and achieve ultimate sublimation..."

At this moment, throughout the Nine Heavens, in all the major forbidden zones, ancient existences were startled, then suspicious, and then calculating.

Not just the Nine Heavens.

Even in the Immortal Realm, some ancient and supreme faction experts vaguely sensed something.

And these experts who could sense it were all incomparably ancient, having experienced several epochs.

Some had even personally experienced a certain terrifying upheaval.

"Sure enough, is it still unavoidable?"

"This upheaval in this lifetime, even if Wuzhong reappears, might not necessarily be suppressed."

Deep within the Nine Heavens Immortal Academy, a descendant of one of the academy's founders shook their head and sighed, their eyes filled with worry.

In the Immortal Court, the Emperor of the Fuxi Immortal Lineage was also deep in thought.

"Past upheavals didn't affect the Immortal Court, and the Immortal Court only symbolically saved some common people."

"But now, it is the weakest period for my Immortal Court in many epochs; we still need to prepare in advance."

If it were the Immortal Court in its prime, with all nine Immortal Lineages gathered.

Then they could naturally ignore the so-called Nine Heavens upheaval.

But now, the Immortal Court itself is on the verge of splitting, precarious in the wind and rain.

At this time, it's hard to guarantee that the Nine Heavens forbidden zones won't have some crooked ideas.

The foundation of the Immortal Court is extremely deep; even if it is currently in a semi-split stage, it is still a behemoth.

And even so, the Immortal Court dared not take this potentially largest upheaval in history lightly.

In a mysterious place in the Immortal Realm, the yin energy was gloomy, with yin soldiers passing through and a hundred ghosts walking at night.

This is one of the ten halls of the Underworld.

A hoarse, cold voice sounded.

"That fluctuation, if there are no accidents, should be the appearance of a new Main Sacrificer."

"The one from the Sea of Reincarnation last time was heavily injured by Wuzhong and has been in a deep sleep ever since, with no successor."

"It seems this lifetime will truly be the most terrifying super upheaval in history, an epic-level Great Cleansing; we have the hope of witnessing history."

"How truly exciting. This is also the best opportunity for our Underworld to rise..."

Jun Xiaoyao had no idea.

The Main Sacrifice Token he signed in for had stirred up a wave throughout the Nine Heavens and the Immortal Realm.

Of course, only those supreme beings at the very top had a premonition.

The ordinary common people and average experts could not possibly have any perception.

At this moment, Jun Xiaoyao was examining this Main Sacrifice Token, lost in thought.

Although Jun Xiaoyao's luck was explosive, and he always signed in for high-star rewards.

But ten-star rewards were still very rare.

Generally speaking, if a ten-star reward is an item, it definitely has great karma.

For example, the Black Blood of the Heavens.

Jun Xiaoyao still felt that the origin of the Black Blood of the Heavens was not simple.

There must be deeper secrets behind it.

It's just that he couldn't reach them yet.

And this Main Sacrifice Token was the same.

A flash of inspiration suddenly crossed Jun Xiaoyao's mind.

He thought of the Main Sacrifice Ceremony that Yun Tianlai had mentioned before.

Only when the Main Sacrifice Ceremony begins do those ancient existences in the Immortal Mausoleum have the possibility of awakening.

What exactly is this Main Sacrifice Ceremony?

And what does the Main Sacrifice Token signify?

On the Main Sacrifice Token, a "five" character is carved.

That is to say, there are at least five Main Sacrifice Tokens.

In whose hands are the other four?

And what is the function of this Main Sacrifice Token?

Where did it come from, and who created it?

What exactly is the relationship between the Main Sacrifice Token, the Main Sacrifice Ceremony, and the Nine Heavens forbidden zones?

And what does it have to do with the Dark Upheaval?

For a time, many questions popped up in Jun Xiaoyao's mind.

It could be said that if it were anyone else, they would feel that all of this was too complex and profound.

It was absolutely not something a young genius could investigate clearly.

But the light in Jun Xiaoyao's eyes became even brighter.

"Interesting, more and more interesting. How many more secrets do the Nine Heavens have?"

"It doesn't matter. On this trip to the Nine Heavens, I will figure out all the secrets."

Jun Xiaoyao stroked the Main Sacrifice Token in his hand, looked at that bright moon, and thought to himself.

Subsequently, Jun Xiaoyao placed the Main Sacrifice Token into his inner universe.

He felt that the Main Sacrifice Token would definitely come in handy at a crucial moment.

After all, it was a ten-star reward; how could it possibly have no use at all?

"Alright, next, let's first investigate the situation of the Nine Heavens." Jun Xiaoyao thought.

He was still completely clueless about the layout of the Nine Heavens, and didn't even know where the Immortal Mausoleum was.

Jun Xiaoyao strolled through the Nine Heavens universe.

Suddenly, he felt something and sensed dense spiritual energy in the distance, similar to the aura of an Undying Medicine.

With Jun Xiaoyao's current Hengsha-level Three-Life Primordial Spirit, his spiritual sense perception range could be said to cover the vast heaven and earth.

Such an investigation was naturally a piece of cake for him.

"Could it be that I just arrived in the Nine Heavens and encountered a treasure land of opportunity?"

Jun Xiaoyao couldn't help but reveal a strange look.

Although the Nine Heavens were filled with spiritual energy and countless secret realms and treasure lands.

But his luck was a bit too good.

Jun Xiaoyao thought as he swept forward.

Not long after.

He revealed a look of surprise.

Because before him was an extremely vast void rift, like an abyss.

Like a great rift valley, it lay across the universe.

But what surprised Jun Xiaoyao was not the abyss rift itself.

It was that around this abyss, there were patches of ancient residual arrays, emitting an extremely terrifying and sharp aura.

Regarding this aura, Jun Xiaoyao was actually not too unfamiliar with it.

"This is... the Wuzhong Killing Array?"
