The only people who entered the secret hall this time were Long Hao, Gu Aotian and Yueji.

This one is the imperial tomb of the Styx country, but the traps inside have been completely eliminated by Yueji, and now they have walked all the way to a large hall, Long Hao saw the main hall in front of him, but his heart was quite surprised, because now in front of Long Hao, there is a large bronze ancient door that is a hundred zhang high, and there are some pictures carved on the door.

Here, there is a Netherworld Bone Dragon engraved, and in this palace, there may be something from the dragon clan!

Long Hao's eyes looked at Gu Aotian: "Gu Aotian, can you open this gate?"

"Young Master, this gate seems to have a kind of power that can restrain me, as long as I get close, my strength will drop immediately!" Gu Aotian shook his head and said.

"We have several thirteenth-order martial artists coming, and there is no way to push open this gate!" Tsukihime also said.

Long Hao walked forward, the weight of this bronze gate is quite a lot, but Long Hao's current ** already has the power of two hundred dragons, Long Hao pushed hard with both hands, but this gate did not move at all.

But at this time, Long Hao's eyes suddenly turned purple and gold, and the real dragon changed!

Long Hao's strength instantly increased by two times, and a purple-gold palace appeared behind him, and the Spirit Palace was summoned by Long Hao.

Long Hao's strength has been increased to seven hundred and eighty dragon powers, Long Hao pushed this bronze gate again, only to see that this bronze gate was immediately pushed open.

Long Hao walked forward, in the hall in front of him, there was a statue, a statue of a bone dragon, this hall is quite huge, in addition to the bone dragon statue in the middle, there are nine bone dragon corpses here, you can feel that they have no life.

And behind the corpses of these nine bone dragons, there is also a black sphere, which seems to be pregnant with something.

"This ...... Could this be a dragon egg?" said Gu Aotian in surprise.

"No, it already has a consciousness of its own, it's not a dragon egg!" Long Hao immediately shook his head and said.

At this time, Long Hao felt a cold aura appear, and a voice suddenly came out from the black sphere: "Kill them!"

What the?

Long Hao, Gu Aotian and Yueji's faces changed at the same time, the life in this sphere actually felt them!

In front of this black sphere, the bodies of the nine bone dragon corpses actually gushed out black mist, and then, as if they had grown flesh and blood, they turned into a pitch-black dragon clan, and each of them actually had the strength of the eighteenth order!

"What is this?" Long Hao's face changed and he said.

"They are the corpses of the Nether Bone Dragon, and inside that ball, it must be the descendants of the Nether Bone Dragon, and it can control these corpses to attack us, Lord Long Hao, be careful!" Tsukihime exclaimed.

Eight eighteenth-order dragon clans made a move, even if the other party was just a puppet, it was quite terrifying.

Long Hao flipped his hand, and a picture scroll had already appeared on his head, only to see eight giant dragons appear in front of Long Hao.

"This ......" Tsukihime's face changed again, and the momentum of these dragons did not seem to be weaker than these Nether Bone Dragon puppets in front of them.

Long Hao actually has so many powerful dragons?

"Destroy them!" Long Hao said.

One after another, the sound of dragon groans appeared, led by dragon thunder, and eight giant dragons pounced out at the same time, and the sixteen dragon clans here began to fight fiercely.

Boom Boom Boom ......

The dragon qi collided here, and the dragon clan here also began to fight, but the strength of the dragon and thunder far exceeded these Nether Bone Dragons in front of them, these Nether Bone Dragons are not real Nether Bone Dragons after all, they are just made into puppets, and their strength is limited.

But why, on earth, are there so many Nether Bone Dragon corpses here?

You must know that just one Nether Bone Dragon corpse is already quite rare, but now there are nine here, and all of them are puppets, which is already quite rare, after all, this is the corpse of the high-ranking dragon clan.

Long Hao's gaze fell on the black sphere, only to see an angry voice coming from inside the sphere: "Get out, if you don't roll again, don't blame me for being rude!"

"What tricks do you have, even if you use it, I am Young Master Long Hao's first dragon genus in the underworld, Uncle Gu Aotian, what kind of thing are you? and dare to threaten us?"

Rumble!

When this dragon qi hit this ball, the ball was immediately shattered, and a powerful dragon power appeared from this ball, only to see a dragon claw stretched out, this dragon claw turned out to be pitch black, only to see a dragon out of this ball.

The appearance of this dragon is so hideous and terrifying, only to see this dragon, half of the body is as black as ink, but the other half, only the skeleton.

"You're even interfering with my promotion to the Celestial Dragon, you're all going to die!" the dragon roared.

Promoted to Tianlong?

The dragon in front of him turned out to be the existence of a half-heavenly dragon!

This one is a real Nether Bone Dragon, and it is a living Nether Bone Dragon, it has been here for ten years, and it originally wanted to break through with the help of the aura here, but at the last moment, it was destroyed by Long Hao!

This Nether Bone Dragon is now a half-bone dragon, and the appearance of the half-sky dragon is obviously what it looked like after defeat.

The Nether Bone Dragon is furious now, and it must kill everyone in front of it before it can vent its anger!

"This ...... It turned out to be a Netherworld Bone Dragon, young master, what are we going to do now?" Gu Aotian said a little jealously.

"What are you afraid of? It's just a Nether Bone Dragon, and it hasn't advanced to the Heavenly Dragon yet, let's kill it, you can get its soul fire, and you can get all the dragon bones on its body yourself, wouldn't it be better!" Long Hao said immediately.

The soul fire of the upper dragon clan, plus the dragon bone of the dragon clan!

If you can devour them all, I'm afraid that Gu Aotian will be able to progress again, and even reach the Heavenly Dragon!

As soon as he thought of this, the flames in Gu Aotian's eyes immediately flourished: "Okay, young master, today I, Gu Aotian, will kill this Nether Bone Dragon for you!"

Long Hao's body jumped and appeared on the top of Gu Aotian's head, only to see Long Hao's palm holding the Dragon Slayer Demon Sword and said, "Do it!"

Bone Aotian directly pounced on the Nether Bone Dragon in front of him, this Nether Bone Dragon was naturally not polite, and its dragon claws slammed towards Gu Aotian.

Even if it didn't succeed in advancing to the Heavenly Dragon, this Nether Bone Dragon was still a high-level dragon clan, and it was also a twentieth-order high-level dragon clan, how could it be afraid of dealing with Bone Aotian?

The dragon claws of the Nether Bone Dragon slapped towards the Bone Aotian, and the dragon claws of the two dragons hit each other's chests at the same time, destroying each other's bones at the same time.
