Xia Yi knew that the strength of the Heavenly Phoenix Demon Beast Phantom was not bad, and with his current strength, he might not be able to defeat it, even so, he still needed to try.

There is an altar in the center of the main hall, which exudes a breath, and the phantom of the Heavenly Phoenix Demon Beast is obviously guarding this altar, Xia Yi is sure in his heart that the secret treasure in this altar is probably the secret treasure that causes the vision.

However, now we must first deal with the Heavenly Phoenix Demon Beast Phantom in front of me, otherwise it is impossible for me to know what the secret treasure is.

The dragon and phoenix sword in Xia Yi's hand came to kill, the spirit sword slashed through the void and killed, the sound of breaking the air roared, the endless sword qi swept wildly, and thousands of sword rain fell to kill.

The phantom of the Heavenly Phoenix Demon Beast snorted lightly, and its body rushed out, piercing the void at an extremely fast speed, approaching Xia Yi, the inhabitation on its body was even more terrifying than before, and it opened its mouth, and suddenly several flames erupted.

Boom!

The Dragon Phoenix Sword was indomitable, directly breaking through the fire ball coming towards him, and the blasting sound continued to resound.

Roar!

Feeling that Xia Yi actually broke through his own attack, the Heavenly Phoenix Demon Beast Phantom was furious, and its body swept in the space, swooping towards Xia Yi, its wings breaking through the void and rolling up the terrifying heaven and earth aura.

Xia Yi held the Dragon Phoenix Sword, his face was slightly solemn, and his body instantly rushed out, facing the Heavenly Phoenix Demon Beast Phantom, the Dragon Phoenix Sword suddenly slashed out, and the endless sword shadow swept through the void to kill.

The Heavenly Phoenix Demon Beast Phantom and Xia Yi's figures were constantly moving in the space, and they were constantly attacking each other, attacking each other.

"This Heavenly Phoenix Demon Beast Phantom Shadow Attack Power is really terrifying!"

Xia Yi stared at the phantom of the Tianfeng Demon Beast, and was slightly shocked in his heart, this was just the phantom of the Tianfeng Demon Beast, if it was a real Tianfeng Demon Beast, he would never be an opponent.

The phantom of the Heavenly Phoenix Demon Beast floated in the space, trembling its wings, and the phoenix eyes stared at Xia Yi, not taking it into account at all, if it weren't for Xia Yi being an intruder who broke into here, it wouldn't appear at all.

"We must speed up and deal with this Heavenly Phoenix Demon Beast Phantom, otherwise if someone else is driven here, there will be a lot of trouble!" Xia Yi was awe-inspiring in his heart, he knew that there was no extra time for himself to waste now, and if he couldn't solve it in a short time, then there would be great trouble.

Xia Yi frowned slightly, although the Heavenly Phoenix Demon Beast Phantom was not a real demon beast, its strength was also not to be underestimated.

Rumble!

Xia Yi suddenly took a step, and his body galloped in the space.

"Senluo Sword Technique!"

Xia Yi resolutely used his sword technique, and the monstrous sword qi bloomed in his own body, rising into the sky, and slashing towards the virtual shadow of the heavenly phoenix demon beast in the void.

Phew!

The Heavenly Phoenix Demon Beast Phantom felt Xia Yi attacking towards him, and his high-pitched voice of disdain resounded, and the flames that kept burning on his body were even more terrifying.

Raging!

The phantom body of the Heavenly Phoenix Demon Beast suddenly had several flames falling towards Xia Yi, and at the same time, the body suddenly rushed out, sweeping towards Xia Yi, and the wings broke through the void, and the sound of breaking the air continued.

Whoop!

The Dragon Phoenix Sword directly broke through the fire ball and turned into scattered aside.

And in the next moment, Xia Yi felt the Heavenly Phoenix Demon Beast Phantom swept over, his face was slightly solemn, and the Dragon Phoenix Sword instantly stood sideways in front of him.

When!

The Heavenly Phoenix Demon Beast Phantom directly slammed into the Dragon Phoenix Sword with its flesh, bursting out with a violent collision sound.

Rumble!

I saw a figure flying out upside down and slamming into the stone wall on the side.

Xia Yi clenched the Dragon Phoenix Sword and half-knelt on the ground, his brows tightly knit and his face was slightly ugly.

Ahem!

Blood overflowed from the corner of Xia Yi's mouth, and he felt that the qi and blood in his body were surging continuously, and the impact of the Heavenly Phoenix Demon Beast Phantom just now had a great impact on him.

He didn't expect that he couldn't help this Heavenly Phoenix Demon Beast Phantom by using the Sen Luo Sword Technique, which could be said to be his strongest means, and in the face of the Heavenly Phoenix Demon Beast Phantom, it didn't play a big role at all.

Phew!

The Heavenly Phoenix Demon Beast Phantom Phoenix stared at Xia Yi, constantly trembling its wings, as if it was quite excited to see Xia Yi helplessly.

Xia Yi couldn't help but look around, his eyes fell on the position of the altar in the center of the main hall, the purpose of the Heavenly Phoenix Demon Beast Phantom was to protect the altar that existed in the main hall, then this altar might be the breakthrough for him to defeat the Heavenly Phoenix Demon Beast Phantom.

Shout!

Xia Yi's body shot out, the aura under his feet exploded, and his speed climbed to the extreme, his target was the altar in the main hall.

The Heavenly Phoenix Demon Beast Phantom felt that Xia Yi was actually heading towards the altar position, and he was furious, and his body instantly rushed out, heading towards Xia Yi, wanting to stop Xia Yi.

Xia Yi naturally felt the phantom of the Heavenly Phoenix Demon Beast coming towards him, but he didn't panic at all, his speed advantage climbed a few points, and he was already approaching the altar position.

Bang!

Xia Yi stepped onto the altar in one step, and then the dragon phoenix sword in his hand decisively slashed towards several stone pillars next to the altar.

Rumble!

In an instant, the phantom of the Heavenly Phoenix Demon Beast trembled, and the aura of the body was rapidly lost, and finally dissipated into space.

The corners of Xia Yi's mouth raised slightly, looking at the Heavenly Phoenix Demon Beast Phantom that dissipated in the void, "This altar is really a bit mysterious, it is guarded by such a terrifying existence!"

Xia Yi looked at the altar, if it weren't for the fact that he found that the Heavenly Phoenix Demon Beast Phantom not only didn't have any consumption in the battle with him, but was also constantly getting stronger, there would definitely be a problem with this.

In addition to this altar in the main hall, there is nothing else, and the only possibility is that the phantom of the Heavenly Phoenix Demon Beast has a great connection with this altar.

Originally, Xia Yi was just guessing, but when he saw the Heavenly Phoenix Demon Beast anxiously trying to stop him, he had already determined in his heart that the Heavenly Phoenix Demon Beast Phantom had a great relationship with the great, as long as he destroyed any place on the altar, the Heavenly Phoenix Demon Beast Phantom would naturally disappear.

"I don't know what the secret treasure in here will be?" Xia Yi looked at the altar curiously, and a faint aura bloomed from it.

Xia Yi stretched out his left hand and gently touched the altar, only to see that the altar trembled violently, and suddenly bloomed with dazzling light.

A stone box instantly appeared on the altar, with many strange patterns flowing on it, which was extremely mysterious.

Xia Yi looked at the stone box that appeared with a little surprise, he didn't expect it to be like this, the same moment the stone box appeared, he felt his heart accelerate, and at the same time, the blood veins in his body surged, as if he was attracted by something.

"What the hell is going on?"

Xia Yi raised his eyebrows slightly, feeling the situation in his body, since he came here to find the secret treasure, he had a feeling of blood connection, as if the things here belonged to him.

"It seems necessary to know what is inside this stone box!"

Xia Yi stared at the stone box, with infinite curiosity in his heart, and now the first thing is to open the stone box.

Taking a step back, the dragon phoenix sword in Xia Yi's hand was slashed out and took the stone box directly.

Rumble!

The dragon phoenix sword slashed the stone box, and the aftermath swept towards the surroundings.
