Bang!

Zhao Yu fell heavily in the Fourth Tree Cave World, and in an instant, the earth and rocks splashed, and a huge impact knocked this place out of a deep pit.

"The suction power in the Fourth Tree Cave World is many times stronger than that of the outside world. Zhao Yu immediately stood up, patted the dust on his body, and used the Void Realm artistic conception to explore the surroundings.

You can't see anything here with the naked eye, but it's a world full of life.

Zhao Yu quickly explored the surrounding scene with the artistic conception of the imaginary realm, surrounded by a large expanse of grassland, which was very desolate.

Suddenly, a strong wind blew, and there was a rustling sound everywhere. Fortunately, Zhao Yu could see all this, otherwise he would be scared half to death.

The space of the Fourth Tree Cave World seemed to have a powerful sealing power, making it impossible for him to shuttle into the Void Realm, nor to fly, but only on foot.

Zhao Yu walked forward while using the Void Realm Artistic Conception to explore the surroundings.

Three days later, there was a sudden thunderous sound ahead, and the earth trembled violently.

In Zhao Yu's imaginary realm, a large black torrent rushed towards it, and the speed was extremely fast, almost shaking the grass within a radius of thousands of miles.

"It seems to be the Iron Cavalry of the Heavenly Army!" Zhao Yu was shocked, he soon found that it was a group of Immortal Armor Heavenly Knights, all of them were wearing black armor, crisscrossing the prairie, looking from afar like a black torrent sweeping across the earth.

Far away, the endless murderous aura had already permeated, making Zhao Yu tremble.

These mounts of the Heavenly Army's iron cavalry are all extraordinary, and they are all heavenly beasts-celestial wolves.

Each wolf was covered in black scales, as big as a giant elephant, and flew like a whirlwind.

Such a behemoth, there are hundreds of them, flying in groups, and naturally it looks like a black torrent.

All the Heavenly Knights were armed with immortal soldiers such as Tiange and War Spears, and they were all murderous.

Soon, Zhao Yu heard the same sound coming from the ground behind him, which was earth-shattering.

It was a torrent of gold, and they were also a large group of Heavenly Army Iron Horsemen, exuding a ferocious aura all over their bodies, but their mounts were all Golden Celestial Lions.

The Celestial Liens is an extremely ferocious celestial beast, each one the size of a small mountain, and it rushes up, causing the earth to tremble violently.

On the back of each Heavenly Lion sat golden immortal armor warriors, each of them holding various immortal soldiers, and their fighting spirit was monstrous.

After half a cup of tea, the Tianshi group and the Tianluo group rushed together and started a big battle. Fortunately, Zhao Yu was able to see this scene with the artistic conception of the Void Realm, and avoided the two groups of Heavenly Knights in time, otherwise he would definitely be trampled into flesh.

Zhao Yu dodged the iron cavalry of both sides from a distance and watched the battle quietly.

"Kill!"

"Roar!"

The shouts shook the sky, accompanied by the roar of lions and wolves, and shook the entire prairie.

The battle was extremely fierce, once the huge lion claw attacked, it was enough to split the mountain and tear apart the void and the earth, and the sky wolf scale armor was also extremely ferocious.

Burst!

A golden celestial lion tore apart a celestial wolf with one claw, and suddenly the blood rushed up a hundred feet high.

Roar!

A celestial wolf's roar shook the heavens and the earth, and it opened its mouth to spew out a fairy light, like a blade of light, and immediately split a celestial lion on the opposite side in half.

"The Celestial Wolf Army, we are going to kill you all this time. The heavenly knight on the golden lion roared, swinging his weapon with all his strength and slashing at the enemy.

"Heavenly Lion Army, maybe you will be wiped out this time!" the Sky Wolf Sky Knight immediately roared, brandishing his giant sword and slashing at the other party.

Poof!

The battle was extremely tragic, and from time to time the knights were beheaded and fell from the backs of the beasts, some of them had their heads cut off, some were stabbed and exploded, and some were cut in two, all of which were blood-stained on the prairie.

Some Heavenly Knights whose strength was comparable to that of the peak powerhouses of the Golden Immortal level were able to soar into the air and fight in mid-air, urging their respective immortal soldiers to fight fiercely.

Zhao Yu used the artistic conception of the void to observe the battles of those heavenly knights, and benefited a lot.

These days, the knight cultivation realm is all very high, and the strength of each one is not lower than that of the peak powerhouse of the Golden Immortal level.

As long as two or three heavenly knights can easily kill themselves, so Zhao Yu, who was watching the battle from afar, was terrified.

If Zhao Yu didn't comprehend the artistic conception of the Void Realm, he would definitely die this time. Once he is caught in the middle of a big fight, he will be slain in a matter of moments.

"How can there be so many Golden Immortal-level peak powerhouses here?" Zhao Yu was very puzzled in his heart.

Half a cup of tea worked, leaving three or four hundred corpses on the grassland. There are heavenly beasts and heavenly knights, and the blood stains the grass red like a stream.

"Celestial wolf knights, hurry up and hand over the Immortal King Flame, or we will kill you all. A Tiens knight shouted.

"Hmph! There has always been a legend about the Immortal King Flame on this grassland, and this time it is clear that the master of our clan accidentally discovered the clue, but was secretly robbed and killed by your Sirius Knight, and you even have to ask us for it in turn. One of the Sirius knights immediately scolded angrily.

At this time, the two sides were still fighting frantically, fierce battles were fighting in mid-air and on the ground, densely packed with human figures, and the Heavenly Lion Group and the Sky Wolf Group each displayed their own talents.

"Immortal King Flame!" Although Zhao Yu was thousands of miles away, he could still hear it clearly with the artistic conception of the Void Realm.

The Immortal King Flame is a strange life substance left behind after the death of the Immortal King of the Heavenly Realm, and if it can be refined, the realm and strength will advance by leaps and bounds.

In the Heavenly Realm, any powerhouse below the Immortal King Realm wants to obtain an Immortal King Flame, and after refining it, his strength will be amazingly improved.

After all, it is extremely difficult to cultivate to the Immortal King Realm. The Immortal King Flame can be used to baptize oneself and sharpen the body and the primordial spirit, with excellent results.

Immortal King Flame is one of the most magical treasures in the Heavenly Realm, once it is refined, it can carry out the most perfect evolution, and the cultivation realm soars to the sky, and the combat power is not much stronger than the powerhouses of the same level, but it is a pity that after countless long years, it only exists in legends.

"This is only in the Zhong Immortal Mansion, how can there be a clue to the Immortal King Flame?" Zhao Yu was extremely shocked in his heart, his heart was pounding, he was currently only in the quasi-golden immortal realm, if he could find and refine an immortal king flame, the cultivation realm might break through to the great power realm at once.

Half an hour later, the battle in the distance finally came to an end, and the two Half-Holy Immortal Realm Heavenly Knights were both defeated, and their Heavenly Knights retreated, leaving a large corpse on the prairie.

In the Origin Immortal Realm, above the Golden Immortal Realm is the Semi-Holy Realm, above the Semi-Holy Realm is the Quasi-Holy Realm, and above the Quasi-Holy Realm is the Holy Realm. Above the holy realm, there are semi-powerful realms, quasi-powerful realms, and great power realms.

The huge bodies of the lion and the wolf are like hills, and the corpses are all over the field.

Suddenly, wisps of flame suddenly emerged from the ground, flashing fairy light, scorching and eerie, instantly burning all the corpses in a moment.
