Zhang Bin and Longmai bargained and finally reached an agreement.

Twenty thousand top-quality spiritual stones are exchanged for one dragon marrow.

In fact, it means that when Zhang Bin can refine dragon marrow in the future, he can refine it as much as he wants until he can no longer refine it.

If another genius who can refine dragon marrow appears in Taiqing Sect, he can also refine dragon marrow, which will also give him 20,000 top-quality spiritual stones.

Both of them are very satisfied with the result.

For Zhang Bin, because he can freely enter and exit the Dragon Blood Restricted Area, he can naturally collect countless top-grade spiritual stones. There is no difference between him getting top-grade spiritual stones and getting high-grade spiritual stones. Therefore, he feels that his own

Made a huge profit.

As for Dragon Vein, if you can get the best spiritual stone that can only be found in the fairy world and let you gestate it quickly, you can pay any price.

The dragon's veins quickly swallowed up all the top-quality spiritual stones and embedded them all into its heart.

It just taught Zhang Bin an extremely complex sharp formation.

However, Zhang Bin soon became frustrated because the formation was too complicated and he couldn't arrange it at all.

In other words, his mental strength is still too weak.

"You are cheating, please return the best spiritual stone to me."

Zhang Bin jumped up and shouted.

"Hehehehe... the deal has been completed. I have taught you the formation. If you can't arrange it yourself, can you blame me?" Dragon Vein said with a smirk.

"But you didn't explain it before?" Zhang Bin frowned and said, "I want to arrange a very powerful sharp array in my body to deal with powerful enemies."

"You are ignorant of gold and jade. This sharp formation is a second-level formation. There is no second-level formation on the earth or other planets. The second-level formation is too precious. It is worth far.

There are more than 20,000 top-quality spiritual stones. And the formations you know now are all first-level formations, so they are too weak." Longmai said.

"Second-level formation? Is there also a third-level formation?"

Zhang Bin said in shock.

"Of course there are third-level formations, which should be classified as immortal formations." Longmai said, "Actually, the second-level formations are also considered low-level immortal formations. If you get an immortal formation, you will make a lot of money."

"It's nonsense to make money. The formations that can't be arranged are useless." Zhang Bin was furious, "When I go to the fairy world in the future, I can naturally learn countless such secondary formations. Knowing it in advance now will not help me at all. Unless,

You help me arrange it."

"To tell you the truth, the second-level formation must be arranged on extremely hard materials, which are actually fairy materials. If you cultivate into a dragon body, your body can be compared to fairy materials. Then of course, the second-level formation must be arranged on it.

There is no problem. However, your body is too fragile now. It cannot withstand the second level formation at all. It is useless to set it up, and it will probably collapse in half an hour." Longmai said.

"Collapsed in half an hour?"

Instead, Zhang Bin's face showed a deep joy, and his eyes burst out with scorching light, "Then, will you have super combat power in these half an hour?"

"Before the collapse, of course it is extremely sharp. It can break through the defense of high-grade magic weapons." Longmai said, "However, when it collapses, your palms will explode. If not, you will be killed. So.

, it’s better not to arrange it.”

"It's just a formation, will it explode?"

Zhang Bin was stunned and almost suspected that Longmai was talking nonsense.

"You can't predict the horror of the secondary formation." Longmai said, "How about this, you take an extra hard material, and I arrange the secondary sharp formation on it. Make it a big killer? But?

This killer weapon only has a lifespan of a few days."

"This is a good idea." Zhang Bin said happily, and immediately took out a lot of materials and treasures from the space ring and piled them on the ground.

"Rubbish……"

Dragon Vein said disdainfully, "Only your Dragon Claw in Longchi can set up the second level formation, but it can only last for three days."

"How can you see through my dragon pool?"

Zhang Bin's face showed surprise and confusion.

"Longchi Longchi, there is a word for dragon, so naturally it cannot stop my prying eyes. I am the real dragon in the future."

Dragon Vein said proudly, "However, if you can cultivate into a real dragon in the future, I will naturally not be able to see inside."

"Um..." Zhang Bin touched his forehead, "The dragon claw is too big and heavy. I can't even pick it up even if the sharp array is deployed."

"Don't you have mastered so many formations? Then arrange the weight reduction array, scaling array, and diamond array inside, and you can use it." Longmai said.

"Damn it...did you take a peek at my Jade Eye Jane? Have you learned all the formations in it?"

Zhang Bin jumped up high.

"This... I really didn't understand formations before. You just read the Jade Eyes Slip and I also read it. I learned all the formations, and it also revived some genetic memories in me, and I remembered a second-level formation, Sharp Formation.

..." Longmai said a little embarrassed.

Zhang Bin was completely speechless. It turned out that by practicing here, Longmai could know almost all the secret techniques he practiced.

It seems that I have suffered a big loss.

However, he didn't care too much, and he also got a lot of benefits from Dragon Vein.

In the future, I may also cultivate to become a real dragon and become a family member with Dragon Vein.

Immediately he took out the dragon claw and said regretfully: "Such a huge dragon claw is a very good weapon refining material. It was a pity that the second level sharp formation collapsed after three days."

"What's such a pity? This Dragon Claw is just better trash."

Longmai said lightly.

"This dragon should have cultivated to the Ascension Stage before it was alive. Maybe it was made into the bones of a real dragon. Its claws are garbage?"

Zhang Bin said in shock.

"True Dragon's Bone? You are too naive." Longmai said, "Since the formation of the earth, many civilizations have been born, including the flying dragon civilization. But no dragon has cultivated into the True Dragon's Bone. Otherwise, I would definitely be able to

You can feel it. How can it be so easy to cultivate the true dragon bone? It takes long years and too many adventures.

Without my help, there is no hope at all. According to the information on your Jade Eye Slip, this dragon claw can be refined into a top-grade magic weapon at most. Its hardness is far inferior to that of the heaven and earth spiritual treasures. But the bones of the real dragon are stronger than

The heaven and earth spiritual treasures are much harder and can be compared to fairy materials. Therefore, the comparison between this dragon claw and the bone of a real dragon is like mud compared to steel."

"Forehead……"

Zhang Bin touched his forehead and felt a little headache. Now he finally understood how difficult it was to cultivate into a true dragon's bone.

He also understood that the dragons in the Dragon Blood Forbidden Zone were celestial dragons, not earth dragons. Even if they had the skills to cultivate into true dragons, they would not become true dragons.

Perhaps, they went to the fairy world to have a chance.

As for myself, it is extremely difficult to cultivate the dragon bones.

I have the help of dragon veins, but I don’t have the skills to become a true dragon.

Even if there are techniques, it is extremely difficult to cultivate the true dragon's bones.

It is extremely difficult to temper the bones in the body to a level that is harder than the spiritual treasures of heaven and earth and comparable to immortal materials.

Dragon Vein requires billions of years of cultivation.

The spiritual treasures of heaven and earth also take heaven and earth to nurture for hundreds of millions or even billions of years.

He shook his head and no longer thought about it, but said: "Even so, this dragon claw is the best material I can get. It's a shameful waste."

"Where is the waste? The dragon claw is still a good material if it is broken into pieces. In the future, if it is melted with flames, it can be made into a powerful magic weapon again!" Dragon Vein said disapprovingly.

"It makes sense." Zhang Bin smiled happily. He was really smart for a lifetime, but he was confused for a while.
