Qin Hao and the others nodded slightly, and after about a few minutes, they reached the bottom of the sea, and then began to disperse to search.

There are no powerful sea monsters and monsters in this sea area, because this radius of tens of thousands of miles is the territory of the black dragon, and the powerful sea monsters and monsters are either killed by it or flee.

The couch of the crouching tiger does not allow others to snore.

The depths of the ocean floor are not pitch black, on the contrary, there is a special substance under the seabed, which makes it very bright when the sun hits the bottom of the sea during the day, and it becomes pitch black at night.

Finally, half an hour later, Qin Hao received Su Xuanji's jade transmission, and she found the cave mansion of the black dragon.

Soon, Qin Hao, Ning Ziyan, Ding Jinyang and Cangtai all rushed over.

Su Xuanji pointed to an undersea mountain peak not far in front of him and said, "There is a cave mansion there, it should be the cave mansion of the black dragon." ”

Qin Hao and the others carefully probed with their divine senses, and there was indeed a cave at the foot of that mountain peak, and there were three quaint big characters above the cave: Black Dragon Mansion.

Ning Ziyan said softly: "This should be a cave mansion in the ancient period, and the three big characters of the Black Dragon Mansion are obviously the fonts of the ancient period. ”

Cang Tai was shocked: "Could it be that the black dragon is something from ancient times?"

Several people next to him looked at him with idiot expressions.

Cang Tai looked puzzled: "What's wrong? Am I wrong? Isn't he from the ancient times?"

Su Xuanji struck unceremoniously: "If this black dragon is a demon beast in the ancient period, do you think it will be so weak? He has already dominated the entire continent, this is obviously the cave mansion in the ancient period, it was discovered, and then got the opportunity inside, and evolved into a dragon." ”

Ning Ziyan nodded slightly, this is a more reasonable answer, the black dragon cannot be a product of ancient times.

Cangtai said with some disberence: "Maybe he is just a grandchild, and his grandfather may be a master in ancient times." ”

……

"Idiot!"

Su Xuanji said a little speechlessly.

Qin Hao also felt that this guy had little brain, and he didn't know what this guy's body was, but it didn't seem to be a certain race that was too shrewd.

Ding Jinyang couldn't help but take two steps to the side, away from this Cangtai, for fear that his IQ would infect him.

Ning Ziyan: "That black dragon should be in the cave at this time to heal its wounds, we will sneak in, waiting for the opportunity to make a move, if it is discovered, then we will do it together." ”

Several people nodded in agreement, and then slowly walked towards the Black Dragon Mansion with a hidden aura.

A few minutes later, Qin Hao and a few people came to the outside of the Black Dragon Mansion, at this time the cave mansion had been completely closed, and the entrance of the Black Dragon Mansion was a top-down stone gate.

The stone gate has fallen, and unless someone opens it inside, it can only be broken by force.

Qin Hao and the others observed, there was no flaw at all, this is an ancient cave mansion after all, although it is no longer in its glory as it was back then, it is not easy to open.

"Do you have a way to open the stone gate? If there is no way, then you can only break it by force. Ning Ziyan said.

Qin Hao opened his mouth and said: "At the beginning, this black dragon was able to enter the cave, which means that this cave can be entered, let's look around, maybe there is a mechanism." ”

Ning Ziyan and the others felt that it made sense when they heard this, and they began to look for it, and at the same time they were thinking about several possibilities.

After searching for a long time and not finding any mechanism, Su Xuanji opened his mouth and said: "There are several ways to open the Ancient Cave Mansion, such as using the power of the bloodline to open, formations, etc., why don't we try the power of the bloodline?"

Qin Hao looked at Ning Ziyan and the others: "What race are you all about, can you do it?"

"Try it, maybe it will work. "Ning Ziyan is the bloodline of the divine beast peacock, and he also has some connections with the dragon clan, maybe it will be useful.

First of all, Cangtai and Ding Jinyang dripped blood on the stone gate, but there was no reaction, followed by Su Xuanji and Ning Ziyan, the blood of the two was extraordinary, and the blood was glowing with a pale golden light, but there was no reaction.

Qin Hao also scratched his fingers, his blood was also pale gold, but it was still glowing with light purple, and the blood dripped on the stone door, and there was no reaction.

But a few seconds later, the stone gate suddenly bloomed, and soon the light was restrained, and the stone gate slowly rose up.

Ning Ziyan's faces were stunned, Wo Ri, it really worked??

This black dragon also belonged to the demon clan in ancient times, and we all belong to the demon clan, why does his blood not work??

Qin Hao was also a little surprised, and couldn't understand why his blood could open the stone gate of this ancient cave mansion.

Ning Ziyan and Su Xuanji looked at him deeply, and they were also puzzled in their hearts, could it be that he had the blood of the Divine Dragon in his blood? ?

"Let's go, let's go in, the black dragon is afraid that he doesn't know that someone has opened the stone door of the cave. Qin Hao hid his breath and walked towards the cave.

Ning Ziyan and a few people also followed, first they walked into a passage, on the stone wall of the passage hung a night pearl the size of a human head, there will be a night pearl every few meters, very luxurious.

Soon they passed through the passage, and in front of them appeared a palace of splendid and magnificence.

Above the entrance of the palace there is a plaque called the Black Dragon Temple.

Ning Ziyan said with his divine sense: "I feel the breath of that black dragon, and it is in this palace." ”

Qin Hao and the others glanced at each other, and quietly approached the Black Dragon Palace, and they passed through the palace gate and entered inside.

In front of the palace, a huge dragon was lying on a jade bed, the jade bed was blooming with fluorescent glow, and pure aura and dragon qi overflowed from the jade bed.

The injured part of the black dragon's body has grown delicate scales, and its injuries are a bit serious, and it cannot be recovered in a short time.

Qin Hao and the others glanced at each other, and then made a decisive move, the two attacked the reverse scales under the dragon, the two attacked the head of the dragon, and Qin Hao attacked the injured part of the dragon with the god of war spear.

This sudden burst of glance caught the black dragon off guard, it didn't expect that there would be cultivators lurking here, obviously the stone gate had been closed, it was the stone gate of the ancient cave mansion, how could it be opened?

Even if someone could open it, why didn't I notice it in the slightest?

"Sneer"

Several attacks directly submerged into the black dragon's body, especially Qin Hao's attack, and half of the God of War spear was completely submerged into the black dragon's body.

The black dragon was furious, his body shook, and Qin Hao and the others succeeded in one blow and quickly retreated.

The palace was large, but it was also very strong, and the battle palace just now did not move.

The black dragon had already been hit hard, but now it was injured on top of injury, its blood-red and ruthless eyes were the size of lanterns, and it glared at Qin Hao and his party angrily: "Who are you?"
