Ji Tianxing didn't have to guess to know that the person who could cause such an earth-shattering movement was no one else except the Ancestor Demon God.

He looked at the depths of the demon camp from afar, and muttered with a solemn face: "Ancestor Demon God, is it finally coming out?"

He had learned about the situation since he got out of the level, and the Ancestor Demon God had already awakened and been reborn when the Heavenly Dragon Pass was broken.

It was more than two months ago, and the Ancestor Demon God Tongtian Three-Day Transformation Supreme had already condensed the Law Body.

However, in the past two months, the Ancestral Demon God has never appeared again.

Even if the Demon Emperor led a large army to attack Zhongzhou City, the Ancestor Demon God still stayed in the Demon Clan's camp and never made a move at all.

Ji Tianxing guessed in his heart that the reason why the Ancestor Demon God didn't make a move was probably to recuperate in the Demon Clan's camp and quickly recover his strength.

After all, when the Ancestor Demon God was reborn, he only had the strength of the first and second levels of the Yuan God Realm.

This strength is not as good as that of the Demon Emperor, and he can't lead the entire Demon Clan at all, let alone be the ancestor of the Demon Clan.

The most important thing is that such strength is simply unable to defeat the army of the three clans and unify the entire Tianxuan Continent.

Therefore, the Ancestral Demon God must use certain secret methods and supernatural powers to quickly recover his strength.

Just when these thoughts flashed through Ji Tianxing's mind, a certain high mountain in the depths of the demon camp exploded with a "bang".

The whole mountain crumbled and shattered, turning into endless pieces of rubble and dust, and bursting out in all directions.

A huge pillar of dark purple light rushed out from the depths of the earth, through the dust, and flew high into the sky.

Ji Tianxing subconsciously looked up and saw a mountain peak as black as ink standing in the sky thousands of feet high.

No, it wasn't a mountain, it was a demon god covered in darkness!

It has a thousand-foot-tall body, as majestic as a mountain, with three heads, six arms, and eight black wings.

A layer of hazy purple brilliance enveloped its body, exuding mysterious and powerful power.

Its six giant purple eyes overlooked the thousands of miles of land below, revealing cold, emotionless eyes.

The four million demon soldiers on this land, more than three million people, demons, and water tribe soldiers are all like ants in its eyes.

"Roar!"

It opened its jaws of blood covered with fangs and let out an earth-shattering roar.

Suddenly, the earth within a radius of hundreds of miles trembled.

The terrifying sonic torrent shook several surrounding peaks and collapsed one after another, shattering into ruins.

An invisible force that enveloped the heavens and the earth was suppressed from the sky, covering a radius of hundreds of miles.

The demons and the soldiers of the three clans in this area were suddenly suppressed with panic, showing extremely frightened expressions.

Even Ji Tianxing, the Golden Dragon Emperor, and the Tianluo Demon Emperor all showed shocked expressions, and their eyes became very solemn.

"What a terrifying coercion! This kind of power has surpassed the Demon Emperor!"

"It turns out that this is the Ancestor Demon God, the legendary three-headed, six-armed, eight-winged god of death!"

"Sure enough, it is worthy of the ancient demon god, even if he has only awakened and been reborn not long ago, and his strength has not yet recovered, it is like a god descending into the world!"

Just when the three of them were full of shock and emotion, the army of four million demons receded like a tide and flocked to the vicinity of the Ancestor Demon God.

Ji Tianxing and the Golden Dragon Emperor were thinking about whether to let the army of the three clans pursue.

At this time, a scene that surprised and shocked everyone appeared.

Millions of demon soldiers rushed to the surroundings of the ancestor demon god, and they all knelt on the ground to worship.

Then, everyone knelt on the ground, closed their eyes, recited the demon spell with a reverent expression, and opened their arms relaxedly.

The posture of the demon soldiers is not only like worship, but also like some kind of ritual.

However, after Ji Tianxing observed carefully, he found a suspicious point.

The four million demon warriors didn't even show a fanatical expression of worship.

Their demeanor and voice are heavy and solemn, and they also contain a strong sense of tragedy!

"What are these demon armies going to do?"

Ji Tianxing frowned suspiciously, feeling more and more puzzled.

The Golden Dragon Emperor and the Tianluo Demon Emperor also kept an eye on the actions of the demon army, and secretly spread their voices and discussed.

At this time, the Ancestor Demon God in the high heavens slowly opened six huge arms, as well as the eight wide wings behind his back.

It lit up with a rich purple light, emitting an incomparably powerful, evil power.

On the ground below, the demon soldiers who were closer to it suddenly burst into blood-colored flames.

In just a few moments, the bodies of those demon soldiers turned into ashes in the blood and fire, condensing into balls of blood-colored light.

At least more than 300,000 demon soldiers were burned to death by blood and fire, turning into black ashes and scattered on the ground.

The overwhelming blood-colored balls of light flew towards the sky one after another, pouring into the body of the Ancestor Demon God like a blood-colored tide.

Immediately afterwards, batch after batch of demon soldiers ignited blood-colored flames in their bodies, and their bodies turned into ashes.

The dark red blood-colored flames lit up the dark sky, covering a radius of hundreds of miles.

As the blood-colored flames continued to spread outward, more and more demon soldiers died.

The blood-colored light in the sky also became more dense, converging into a torrent of blood light that covered the sky and the sun, and drilled into the body of the Ancestor Demon God.

The Ancestor Demon God devoured countless blood-colored light clusters, and the purple light enveloping his body became even richer, gradually turning black.

Its aura has become more evil and mysterious, and its power has grown rapidly.

Not far away, a Terran vanguard army that was relatively close to each other numbered more than 30,000 people.

They didn't have time to dodge and retreat, and their bodies even burned, and blood-colored flames erupted.

In just a few breaths, more than 30,000 Terran soldiers were burned to ashes.

Their blood, energy, spirit, and strength converged into a cloud of blood light, and they also flew towards the Ancestor Demon God.

Seeing this scene, Ji Tianxing and the Golden Dragon Emperor suddenly changed their faces drastically, and they understood the intention of the Ancestor Demon God.

"I understand! Those four million demon army are going to sacrifice their lives to increase the strength of the Ancestor Demon God!"

"Oh my God! This is a sacrifice! Those four million demon armies are going to use the evil sacrifice ritual to dedicate their lives and strength to the god of death!"

"If this emperor is not mistaken, I am afraid that this is the ancestral god sacrifice in ancient myths and legends!"

Hearing the Golden Dragon Emperor's exclamation, Ji Tianxing and the Tianluo Demon Emperor both turned their heads to look at him and asked, "What ancestral god sacrifice?"

The Golden Dragon Emperor's face was gloomy, and he said in a solemn tone: "The ancestral god sacrifice is an ancient sacrifice in ancient myths and legends.

The ancestors or leaders of certain races that rely on bloodline to inherit their power can use this ancient sacrifice to devour the power of all their descendants and quickly increase their strength.

The Ancestor Demon God is the ancestor of all demons, and the army of four million demons is its bloodline descendants.

In a sense, the lives of those demon armies were given by the ancestor demon gods.

Now, in order to quickly increase their strength, the Ancestral Demon God will deprive them of their life and strength......"
