The two of them advanced with all their might, and it didn't take two minutes to reach the location of the Yongle Dragon Cave, which was a military area, and they did not dare to show the water, but circled around the Dragon Cave in the water.

Dragon Cave is also called Blue Hole, Ocean Blue Hole is a rare natural geographical phenomenon on the earth, from the sea surface of the blue hole presents a different deep blue from the surrounding waters, and forms a huge deep hole in the bottom of the sea, which is praised by scientists as "the last heritage of the earth to keep the secrets of the universe to mankind".

According to the information they checked, the Yongle Dragon Cave is basically a vertical cave, the diameter of the blue hole is 130 meters, the diameter of the bottom of the cave is about 36 meters, and the dragon cave is not found to be connected with the open sea for the time being, and the water surface is almost static and does not flow.

In this regard, Li Chengjun explained that the dragon cave here in the dragon tomb is only an external manifestation, and the real dragon tomb is still in another space in the depths, where can be detected by these modern scientific instruments.

The surrounding "Dragon Pit" and "Dragon Cave" are the cemeteries of the important ministers of the Dragon Palace in the South China Sea, from his induction, at least there are the cemetery of the Prime Minister's family, the cemetery of the Whale Shark General's family and the cemetery of the shrimp soldiers, the crab generals, and the Yaksha of the patrol, some can be observed from the outside and are different from other sea areas, which is the so-called Dragon Cave, and some can not see the changes, the same as other places.

Li Chengjun also wanted to come out of the dragon tomb and explore the other cemeteries of important ministers in turn, to see if he could also catch some treasures or something, and it was not a trip in vain, but Yang Yi did not dare to agree, looking at his eyes shining, maybe he could dig up all these tombs, if there are living dragons in the entire South China Sea, it is strange that they must not be torn apart.

Yang Yi and Li Chengjun entered the dragon cave, there was no light at night, the dragon cave was pitch black, only some special plankton emitted a glowing blue light, like fireflies in the water, but these glowing creatures could not avoid the underwater creatures, and they could shine in the dark sea water but were the best targets, and they saw many luminous creatures being devoured by fish or other creatures along the way.

After arriving at the bottom of the sea, Yang Yi and Li Chengjun both turned into a meter-long ichthyosaur and communicated with their minds.

"This should be the bottom of the Dragon Cave, I didn't find anything special except for the black spots, huh! What is that?"

Yang Yi circled around the bottom of the cave, in addition to the dark stone wall, there were uneven rocks, quiet like a deep well, and suddenly Yang Yi found that in the uneven rocks at the bottom, there were many mud and sand covered places, and he vaguely saw something hidden inside.

"Some big mussels, their clan is considered a servant of the Dragon Palace, and they also play the role of guarding the tomb, looking at these should be many years, many of them are more than a thousand years old, but the same mussels can't become essences, many of them are dead and lifeless, there should be pearls in them, do you want to get some?"

"Of course, if you don't charge some, how can you get up here and take a trip!"

Yang Yi heard that it was just an ordinary seabed shellfish, so naturally he would not let go of these big mussels, but he used the dragon ball to secrete a trace of spiritual water on his fingertips, approaching the mouth of the mussel shell covered with mud and sand, the big mussel naturally opened, and a white pearl the size of an egg appeared in front of him, and there were many thumb-sized pearls next to it, most of which were perfectly round, and some were oval or irregularly shaped.

He took out the pearls that were perfectly round, and the pearls that had not been formed remained in them, and a drop of spiritual water was dripped into the shell of the mussel, so that it could be closed, and when it came back in a few years, it should be possible to harvest a stubble.

"I said that there is no need to give them spiritual water, just let them spit out the pearl with a spiritual control technique, it's too wasteful!" Li Chengjun seemed to be feeding the clam spiritual water next to him, and couldn't help muttering.

Yang Yi didn't pay attention to him, and continued to take pearls in his own way, there are not only sea mussels here, but also a lot of giant clams, but in Li Chengjun's mouth, these things are all mussels, big shells of the same family, not much difference.

In the Han Dynasty Fu Sheng's "The Great Biography of Shangshu", it is recorded that King Wen of Zhou was imprisoned by the King of Shang in this place, and San Yisheng used the story of the King of Shang to pay tribute to the King of Zhou in exchange for the King of Huiwen. This is the origin of the name of the clams in later generations, as Li Chengjun said that there are too many kinds of this family, for a dragon clan like him in the South China Sea, he can only remember that the unified name is Da Beng, and there are maids in the Dragon Palace called Mussel Girl, that's all.

In the Qing Dynasty, the pearls worn by the Liupin officials when they went to court were made of clams. At the same time, as one of the seven treasures of Buddhism, like amber and coral, in Tibetan Esoteric Buddhism, the eminent monks and lamas also wear the clams as prayer beads and chant them.

Yang Yi kept in his hands, opened these clams and pearl mussels with spiritual water, and then took out the best quality pearls, and finally gave them a drop of spiritual water.

This one took more than an hour, the bottom of the dragon cave with a radius of more than 30 meters, there were such clams and pearl mussels everywhere, some of them were pressed together in layers, he collected no less than 100 pearls the size of eggs, the colors were common white pearls, there were also golden pearls and black pearls, and there was a kind of red pearl that was as red as blood, this kind of pearl Yang Yi saw for the first time, and there were very few mussels that produced this kind of pearl, he found a total of three large, more than ten thumb-sized ones.

In a corner at the bottom of the cave, he also found some clams and mussel shells, which should have died in the past countless years, all piled up in the corner, most of them have been jaded, Yang Yi looked good-looking and threw them into the Dragon Ball space, soaked in spiritual water in the corner of Lingshui Lake, planning to have time to clean them again.

Now there are many clams products and ornaments in the world, and the collection industry is also a very valuable kind of clams products, save time to find a master to process it, maybe it is a new channel, that is, do not carve and process, these as jewelry at home is also very good-looking.

"Almost, let's go into the real dragon tomb, these things outside, you want the entire South China Sea to be more, don't waste your time here!" Li Chengjun and the others were really a little impatient.

"Well, let's go, do you know how to open the ban?"

Yang Yi took out some spiritual water and scattered it at the bottom of the cave to supplement some nutrients for these clams and pearl mussels, and then turned to Li Chengjun and asked.

"Only the dragon clan dragon balls with pure blood can be opened here, mine is definitely not good, the lord your ancestral dragon ball is the ancestor of ten thousand dragons, and the prohibition of the dragon clan cemetery will naturally not stop you!" Li Chengjun said.

"Okay, you wait a minute, I'll let Xia Li and a few of them come out!"

Yang Yi said and summoned the four shrimp soldier commanders of Xia Li, let them stay around, and then summoned the ancestral dragon ball, and the brilliance illuminated the entire dragon cave, but fortunately, this is a few hundred meters deep under the sea, even if the brilliance shines, it can't be dispersed, so there is no need to worry about attracting people over.

I saw that a transparent film suddenly appeared at the bottom of the cave, and the walls of the entire dragon cave became transparent, and after a tremble, a three-meter square door was formed.

After entering, Yang Yi and several people were stunned, including Li Chengjun, for the so-called dragon tomb, he only heard its name, but never saw its true face, only to see that this space was made of crystal, flashing dazzling light, it turned out that he just heard that the legendary dragon clan likes luxurious and shiny things, but he didn't expect it to be true.

They walked in this crystal world, feeling that they were their own figures up and down, left and right, and the six of them seemed to be walking in a world composed of mirrors, which was dazzling, and Li Chengjun, who didn't know how many years had passed, couldn't stand this kind of stimulation, so he could only squint his eyes as much as possible.

Yang Yi released the dragon ball and put it on top of his head, and this weird feeling gradually disappeared, but the moment the dragon ball came out, countless loud dragon moans sounded in this space, and it lasted for a long time, as if it was welcoming the ancestral dragon ball.

I saw that the scenery of the space changed, the crystal world disappeared, and then a majestic mountain appeared, the trees were green and green I don't know how far, a thatched hut appeared in front of me, and a stone tablet in the thatched house, and a green dragon swam in the stele.

Yang Yi and the others took a closer look, and a piece of handwriting appeared on the stone tablet, and the content read: "The Ten Princes of the Dragon King of the South China Sea, the Jade Green Dragon Ao Yuantu, the immortal god calendar is 1.29 thousand years, resisting the invasion of foreign lands and being seriously injured, only the damaged dragon balls take the initiative to enter the dragon tomb, if there is a dragon clan need, you can take the dragon ball and fuse it, and hope that he will fight against the alien race with you one day!"

Then I saw a green dragon ball appearing in the stone tablet, missing a third, and trembled after seeing the ancestral dragon ball above Yang Yi's head, and then accelerated and flew over, hitting the ancestral dragon ball and merging into it.
