The sudden change made Ji Tianxing and the three princes stunned.

Both of them stared at the edge of the Ten Thousand Gu Realm, watching the multicolored light curtain crack little by little, revealing dense cracks.

A moment later, there was a muffled sound of 'bang bang bang' followed by an angry beast roar.

The two of them suddenly guessed something, and their faces changed.

"It's over! Our fight is too loud, attracting ancient beasts!"

Ji Tianxing hid in the mountains and rivers, thinking solemnly.

Although, the sudden appearance of the Ancient Beast was about to blast through the Ten Thousand Gu Realm, giving him a chance to escape from the Ten Thousand Gu Realm.

But he knew that there was definitely more than one ancient beast outside the realm, and its strength must be in the soul refining realm.

At that time, even if he escaped from the Ten Thousand Gu Realm and got rid of the entanglement of the Yin Ghost Gu, he would still be bombarded and killed by a group of ancient beasts, and he would still be unable to escape death.

"Damn! I forgot that this burial star sea is full of ancient beasts!"

The third prince's face was the most embarrassed, his fists were secretly clenched, and his heart was full of anger and unwillingness.

He finally seized the opportunity to trap Ji Tianxing in the Ten Thousand Gu Realm, and he could immediately ravage and torture him to death.

But he saw that he was about to succeed, but suddenly several ancient beasts appeared to intervene.

How could he not be angry?

The loud sound of "bang bang bang" kept coming, and it became more and more rapid and dense.

The multicolored light curtain that covered the sky and the sun trembled more and more violently, and the cracks became bigger and bigger.

Finally, with a 'boom' earth-shattering sound, the colorful canopy in the southeast was instantly shattered by the bombardment, and a big hole collapsed!

Around the large hole with a radius of tens of meters, dense cracks burst out, bursting out of overwhelming fragments of light.

Immediately after, a swarthy giant beast that was as huge as a mountain and looked like a giant ape passed through the big hole and burrowed into the Ten Thousand Gu Realm.

This is an ancient alien beast Decepticon with a height of 100 meters, a huge body like a mountain, and an extremely rough and tyrannical appearance.

It has extremely thick limbs, and a pair of dark red wings on its back, surrounded by dark red sky fire.

A pair of huge dark red eyes like a water tank, like fiery red gems, contain the domineering majesty of all beings.

It was covered with strong and bulging muscles, as tough as a magic weapon, and full of earth-destroying ferocious force.

The most terrifying thing is that Ji Tianxing and the Third Prince can clearly sense that the strength of this Decepticon is far ten times higher than them, at least reaching about the sixth level of the Soul Refining Realm!

It was this terrifying Decepticon Ape that blasted open the Ten Thousand Gu Realm with an incomparably strong and violent attitude!

One of them has just reached the Soul Refining Realm, and the other has not yet reached the Soul Refining Realm, and in front of the Decepticon Ape, the weak one is like a chicken, and he is vulnerable!

Moreover, the Decepticon is not acting alone, it also leads the six ancient beasts with the strength of the Soul Refining Realm!

The six ancient beasts had different appearances, some looked like beasts, some looked like birds, and one of them was actually a giant snake thousands of meters long!

They frantically attacked the Ten Thousand Gu Realm, tearing the huge hole open and then shattering the entire multicolored canopy.

With the crisp sound of "click", the colorful canopy that shrouded a radius of hundreds of miles was shattered in half in an instant, and gradually collapsed.

The third prince's face became gloomy as ice, and his angry eyes almost erupted into fire.

Fortunately, he used the power of the source of ten thousand Gu to cast the Ten Thousand Gu realm, so after the domain was shattered, he was not counterattacked by the force.

At this moment, the figure of the Decepticon rushed into the sky in a flash, and came to the middle of the field as fast as a streamer.

"Roar!"

Its eyes were fixed on the giant blue ball suspended in the sky, and when it saw the dense millions of Yin Ghost Gus, it immediately let out a roar.

It unexpectedly opened its bloody mouth and spewed out an overwhelming dark red sky fire, enveloping the entire dark blue giant ball.

"Boom!"

The incomparably powerful and furious Heavenly Fire blasted the dark blue giant ball out on the spot and smashed it into the ruins dozens of miles away.

The millions of Yin Ghost Gu wrapped in the seal of mountains and rivers were burned to death by the dark red sky fire on the spot, turning into wisps of blue light and dissipating.

The Yin Ghost Gu, who was lucky not to die, all fled in panic and flew towards the multicolored altar in the sky, like a swarm of bees returning to their nests.

When the Ten Thousand Gu Realm existed, they were of course indestructible and almost immortal.

But after the domain is broken, they lose the support of the domain power, and they become much weaker.

The terrifying heavenly flames swept through the sky, burning those Yin Ghost Gu who fled in panic again.

Then, the Decepticon followed the direction of the Heavenly Yin Ghost Gu and looked at the multicolored altar in the high sky, as well as the three princes at the top of the altar.

"Roar!"

It let out another roar, and in a flash its figure rushed towards the heavens, swinging its huge fists and slamming it into the multicolored altar.

Its fists were as big as houses, wrapped in a layer of dark red heavenly fire, containing the power to destroy the world.

Moreover, its speed was extremely fast, so that the three princes had no time to resist and fight back.

When he saw the Decepticon Ape killing in a rage, his face suddenly changed, and he was about to flee while controlling the multicolored altar.

Unfortunately, his speed was too slow.

"Bang bang!"

With an earth-shattering loud bang, the Decepticon's fists slammed into the multicolored altar, knocking the altar and the three princes flying.

"Whew!"

The hundred-meter-high multicolored altar was actually sent flying more than thirty miles away, bursting with colorful spiritual light, and its aura was extremely disordered.

Fortunately, the Colorful Altar was a Gu Dao artifact after all, and it was still unscathed after withstanding the frontal bombardment of the Decepticon Ape.

Although the third prince was not hit head-on by the Decepticon, he was also shocked, his face turned pale, and blood spurted wildly from his mouth.

"The strength of this Decepticon has definitely reached the sixth level of the Soul Refining Realm! it must be the leader of these ancient beasts nearby!"

This thought flashed through his mind, and he immediately slipped into the multicolored altar and fled into the distance without looking back.

At this moment, it is still important to save his life, and he can't care about dealing with Ji Tianxing at all.

Under his manipulation, the multicolored altar quickly shrank to a size of ten meters, erupting with multicolored flames of light, bursting with unparalleled speed, piercing the sky like a meteor.

"Roar!"

The Decepticon obviously refused to let him go easily, and after roaring twice in the sky, it immediately turned into a stream of flames and launched a hunt for him.

At the same time, in the ruins dozens of miles away, a figure suddenly appeared, it was Ji Tianxing.

The strength of the mountain and river seal was completely exhausted, and the surface was still covered with dents, and it was slightly damaged.

Ji Tianxing put away the mountain and river seals, and was just about to fly into the sky to search for the figures of the Decepticon and the Three Princes.

At this time, the six-headed Ancient Beast of the Soul Refining Realm discovered him, and immediately roared and pounced, wanting to surround and kill him.

His face suddenly changed, and without hesitation, he sacrificed his sword fetus, performed the stunt of flying with the sword, and desperately escaped in another direction.
