"This tooth mark is really poisonous!" Lin Chen looked confused, and he couldn't get rid of the tooth mark on his arm.

"This is a soul blood mark, which is naturally difficult to erase. The Blood Demon Dragon said suddenly.

"Soul blood seal?"

"Yes, it is a kind of memory blood mark of the soul, which will not cause any harm to you, it seems that this little girl wants to remember you, and I am afraid that it will kill you. ”

"Rub it, can there be a way to get rid of it? If my daughter-in-law sees it in the future, I can't argue with it!"

"Simple, kill her directly, and the soul blood seal can be lifted. ”

"If this doesn't work, is there any other way?"

"No, this is what happened to you! not worthy of sympathy!" the Blood Demon Dragon looked very proud.

"Can't you really be a little sympathetic when you're old?"

"The deity is originally a cold-blooded demon dragon, don't talk about any feelings with the deity, vulgar!"

"Well, you've always won. ”

"Don't talk nonsense, don't you want the treasure in this dragon cave?"

"Baby?" Lin Chen's eyes lit up, and he asked, "This dragon's blood stone is digging hard, what other treasures can there be?"

"Where the Holy Dragon fell, there must be treasures, not to mention the deep dragon veins. "The Blood Demon Dragon is the color of the Dao.

"It makes sense, next time I don't know when I'll have the opportunity to get in again, if there really are any treasures that have to be scavenged away!" Lin Chen was so excited that he directly ignored the tooth mark.

But see!

The dragon remains inlaid on the stone wall are still extremely shocking and shocking.

"With your old eyes, do you think this dragon skeleton is still useful?" Lin Chen asked in amazement.

"It's been silent for too long, it's almost a fossil, and the dragon spirit qi has also been absorbed, so it doesn't have any special value for your cultivation and promotion. The Blood Demon Dragon replied.

"That doesn't work?" Lin Chen was a little disappointed.

"I can't say that, if it's used as a refining material, it will definitely not be inferior to the Heavenly Artifact Stone. ”

"Rub it!

"Of course, this is the Holy Dragon Bone, and there are not many substances in the world that can compare to the strength of the Holy Dragon Bone. The premise is that the spiritual fire you control can be refined into a holy dragon bone. ”

"Just because you can't do it now doesn't mean you can't in the future. Such a valuable treasure, how can I dig a few back!" Lin Chen's face was full of excitement, if it could be compared to the value of the Heavenly Artifact Stone, it would be considered a treasure.

I can't help it!

Lin Chen showed the dragon soul knife in his hand, and first tested it with five layers of skill, but it was difficult to shake the dragon bone.

Then!

If you slash violently with the power of ten layers, it is still difficult to damage the keel in the slightest.

"Strong! It's too strong! If it can be refined, it can be used in the battle weapon, but I don't know how much it can be strengthened!" Lin Chen was very excited, the strength of the holy dragon bone really did not disappoint him.

Unable to hurt the Holy Dragon Bone in the slightest, Lin Chen started along the stone wall inlaid with the Holy Dragon Bone. Although the stone wall was still extremely hard, Lin Chen could still split the travertine.

Boom!~

The travertine exploded, and a broken bone fell.

Lin Chen carefully identified that the material of this holy dragon's bones was indeed strong and extraordinary, and even the Heavenly Artifact Stone could not be compared. It's a pity that this dragon skeleton is already a dead air, otherwise it would have had a greater effect.

Bang!~

Another knife splits the travertine.

Suddenly!

In the cracks, faint bursts of powerful and abnormal aura seeped out.

"What is this?" Lin Chen was shocked.

"What else can there be, inside the keel, there must be dragon veins, otherwise you really think that the dragon blood stones in this are all grown by themselves. The Blood Demon Dragon said with excitement and anticipation: "Hurry up and chisel, maybe there will be a bigger treasure!"

"Chisel! must chisel!" Lin Chen also seemed to have been beaten with chicken blood, Lin Chen frantically brandished the dragon knife, smashing layer after layer of cave walls.

Bang!bang!~

Gravel flew sideways, and Lin Chen was collecting keels while digging caves.

Finally!

Rumble!~

The thunder was heavy, the blood dragon roared, and Lin Chen slashed out an inner hole with a single sword.

"And the dark hole?" Lin Chen was surprised.

Then!

Streams of strong and pure dragon vein aura, like a flood bursting from the embankment, surging mighty and surging, instantly filled the entire undersea cave.

"The breath of the dragon! It really is the breath of the dragon!" Lin Chen was ecstatic, excited, under the impact of the dragon vein aura, Lin Chen felt that the dragon blood in his body couldn't help but boil on his own.

It felt like it was about to burn.

If Lin Chen is allowed to cultivate here, he can definitely achieve the divine effect of a thousand miles in a day.

"Haha! It's developed! It's really developed! It's a peerless treasure! No wonder that Sea Dragon King is so fat, it's obvious that he has the blessing of the heavens and the earth!" Lin Chen laughed excitedly, and then rushed directly into the cave.

Surprised!

In the dark hole, the divine light is glazed, dazzling like a rainbow, and the crystal bright dragon veins like tree vines are intertwined vertically and horizontally, extending in all directions, and the layers are networked, all over the entire dark hole.

"It's really a dragon vein, even stronger than the deity imagined, but it's a pity that the deity doesn't have a sound dragon body, otherwise it will be able to go straight to the fairyland. The Blood Demon Dragon sighed bitterly.

"What about me, can I absorb it?" Lin Chen asked.

"Of course, and you have already reached the bottleneck, if you absorb the dragon vein aura again, you will be able to directly break through to the mortal realm. ”

"Breakthrough?"

"Don't you want to?"

"It's not that I don't want to, and the dragon martial arts I have cultivated will have to attract a heavenly tribulation across every level of the realm, but now I feel that it is not the right time to cross the tribulation here. Lin Chen felt entangled.

"When will we talk about a breakthrough?"

"Of course, I have to be cautious, if I break through here now, I will definitely alarm all the Kraken clans in the Eastern Sea, and then I will have to become the target of everyone. ”

"If it doesn't work, then save it first. ”

"That's right, I have two big orbs here, I should be able to eat this dragon vein!" Lin Chen smiled, it just so happened that the sea spirit bead had consumed so much energy, and it could be replenished from the dragon vein.

The Qiankun Holy Bead can transform the spiritual source of various attributes, and it can also store the spiritual source of various attributes. Just to preserve the attributes of the spiritual source, you can't use the Qiankun Sacred Bead anymore.

Just as he was about to absorb the dragon vein, Lin Chen suddenly discovered that at the core of the dragon vein, there was a large jet-black sphere with a diameter of three feet.

"What is this?" Lin Chen's face was full of surprise and stepped forward.

I can't help it!

Lin Chen tried to move the black ball, but he was shocked to realize that the black ball was as heavy as a mountain, with extremely strong density and quality, and it was estimated that it weighed at least one million catties, which was not logical at all.

Plain as day!

There is a strong prohibition inside the black ball, or there is a powerful energy sealed inside the black ball, compressing it into one, it will be so heavy and terrifying.

"Long Dan! it's the Holy Dragon Neidan!" the Blood Demon Dragon exclaimed.

"Holy Dragon Neidan!?" Lin Chen was surprised.

"Yes, this is the real Kui Bao! Boy! You're really lucky!"

"But I feel that this black ball is so heavy that I don't feel any energy at all?"

"Nonsense! This dragon pill should have been self-sealed by the Holy Dragon before it fell, if it survives, then it will be your turn?"

"But if I can't crack it, it's useless, and there is a good chance that there is a holy dragon soul in this dragon pill. If this great god is awakened, I don't know how the boy died. Although Lin Chen was moved, he was very jealous.

"If the dragon soul still exists, it will naturally not be allowed to be assimilated by the spirit vein. The Blood Demon Dragon Zhengse said: "This Dragon Pill seals itself, but it doesn't want to be easily stolen, let alone be obtained by demon beasts, and destroy the heavens." The reason why I exist here is because I am afraid that I am looking for someone who is destined. ”

"Then what do you mean by the old man, the kid is the one who is destined?" Lin Chen was stunned.

"You have bumped into such a bloody thing, will this dragon pill have nothing to do with you?" the blood demon dragon said in a serious tone: "And the power contained in this dragon pill is vast and unpredictable. Now that you don't cultivate enough, you naturally can't crack it, so put it away and save it first, and it will be of great benefit to you in the future. ”

"Also, whether it's useful or not, you can't cheapen others, so the kid accepted it first. Lin Chen smiled, he didn't plan to let go of this dragon pill.

Then!

Lin Chen started again, but he still couldn't move the Long Dan black ball in the slightest.

"Don't move!" Lin Chen felt helpless.

"Fool! Now that the Dragon Pill and the Spirit Vein have been fused together, forming a powerful Dragon Vein, and now that the Dragon Vein is flourishing, you naturally can't shake the Dragon Pill!" the Blood Demon Dragon said with disdain: "Don't you want to absorb the Dragon Vein? Suck the Dragon Vein Aura in it first, and you will be able to release the Dragon Pill imprisonment in a little bit." ”

"Makes sense. Lin Chen nodded slightly, and was a little jealous: "With your old experience, is this really okay?"

"If you are cowardly, just leave, lest you say that the deity is pit you, and then you will have to complain about the deity!"

"Don't complain, don't coward, the kid will listen to your old man. ”

"If you are so obedient, the deity will be much more worry-free. Although the Blood Demon Dragon didn't show up, it must be rolling Lin Chen's eyes.

"I'll listen to you in the future. Lin Chen smiled, and at the same time, the Sea Spirit Bead and the Qiankun Holy Bead appeared, ready to absorb the dragon vein aura.

Moreover, if the dragon vein aura can be transferred to the ancestral land of the Lin Mansion, the Lin Mansion will be able to produce dragons from generation to generation, geniuses, strong people, and prosperous families like the ancient family in the future.
