If Zhang Bin's body refining speed is followed, it will take tens of thousands of years for the bones to be cultivated to the point where they are close to the dragon bones, and then the bone marrow of the senior Dragon Vein can be transplanted into it to further nourish the bones and body. Only then can he truly

After cultivating into dragon bones, you can also cultivate in dragon blood.

However, if these dragon marrow grasses are obtained and refined into strong marrow pills, the time can be greatly shortened.

"Oh my god, one millimeter grows in ten thousand years, but the dragon marrow grass here is almost 20 meters long."

"Master, I feel that these dragon marrow grasses have a lifespan of nearly 200 million years."

Xiaoqing said excitedly in Zhang Bin's Dantian.

"Oh my god, the 200-million-year-old dragon marrow grass is definitely a super magical elixir of heaven and earth, no less than dragon energy. I have once again found an elixir of heaven and earth that can be compared to dragon energy. I am

Great blessings come to heaven." Zhang Bin was extremely excited.

Now he clearly understood that this giant dragon must have been very powerful during his lifetime and should have cultivated to the ascension level.

It was killed by a stronger giant, and its marrow slowly flowed out, nourishing this land.

After billions of years of gestation, dragon marrow grass finally emerged.

This kind of dragon marrow grass is definitely the best and its value is inestimable.

Moreover, there are so many here, and I can even trade a lot of medicinal materials with Gauss.

"Dragon marrow grass? What kind of elixir of heaven and earth is it?"

Han Bingyun asked curiously.

After hearing Zhang Bin's explanation, Han Bingyun was completely shocked.

"Husband, you are indeed a great blessing. In the future, we may really ascend to the fairy world."

Han Bingyun said excitedly, "But, what are you going to do with the dragon marrow grass here?"

"Of course it will be transplanted into the Golden City immediately. Dig out the soil as well," Zhang Bin said.

"Elixirs like the powerful spinach are guarded by extremely terrifying monsters. Doesn't the dragon marrow grass have no monster guards?" Han Bingyun said seriously.

"Yes, it is the bone dragon in the sky. No monk dares to come here."

Zhang Bin said with a smile.

"Don't be careless. Try it first."

Han Bingyun said.

"The land here is relatively dry. It should be because the terrain is too high. Therefore, I can see to a distance of about three meters underground without any monsters."

Zhang Bin said proudly.

"What's inside the dragon bone? Can you see through it?"

Han Bingyun said.

Because the keel was cut off, there was a hole in the center of the keel.

Maybe there are scary monsters hiding inside.

"There was no sense of danger."

Zhang Bin and Jiang Xue said almost at the same time.

However, Zhang Bin still picked up a stone and threw it into the hole of the dragon bone.

After a while, there was still no monster coming out.

"Hey...you guys think, if I arrange a teleportation array in the hole of the dragon bone, can the bone dragon detect it?" Zhang Bin had an evil smile on his face.

"It is indeed a good idea. No matter whether the bone dragon can be discovered or not, we must set up a teleportation array. If the bone dragon cannot be discovered, then the treasures of this world belong to us."

The beautiful eyes of Han Bingyun lit up.

"Husband, you are so smart."

Jiang Xue also praised it.

"Quack quack..."

Zhang Bin laughed strangely, and he immediately drove the White Bone Peak and slowly flew to the entrance of the Dragon Bone Hole.

Observing carefully, Tutu was also scanning hard.

This hole is the hole in the middle of the keel's spine. This spine is terrifyingly huge, nearly a thousand meters high.

However, the hole is very small, only about two meters.

Therefore, the thickness of the keel is astonishing.

The bone quality is extremely fine, crystal clear like jade, without any decay, and the incision is extremely smooth.

Exudes amazing sword intent.

It has not dissipated even after billions of years.

This shows how powerful the master who killed the dragon was.

"Master, maybe this kind of sword power is too terrifying, and no creature dares to appear here. This is a kind of pressure on the soul. Therefore, I did not scan any monsters in the hole." Tutu said.

The red mist in the hole is also very rich, and the light is dim. It not only blocks the penetration of spiritual consciousness, but also blocks the vision.

But it still couldn't stop Tutu from scanning.

"Great, this sword intention has helped me a lot."

Zhang Bin was so excited that he immediately flew into the White Bone Peak.

Go deep inside quickly.

This is a deep hole with a slight curvature.

There is still a lingering aroma in the air.

It is obviously the scent left behind by the dragon marrow.

Unfortunately, Zhang Bin did not find any drop of dragon marrow, which had obviously flowed out long ago.

Otherwise, it is another super good treasure.

Dragon bones can be refined into magic weapons, but dragon marrow can be refined into elixirs, which can transform monks' bone marrow. The effect is no less than that of dragon marrow grass.

Finally, Zhang Bin drove the White Bone Peak to the deepest part of the cave.

There really aren't any monsters here.

"Hehe... this will be our safest cave from now on."

Zhang Bin flew out with two beauties.

Of course, they all wore armor.

Otherwise, the terrifying red mist will hurt them.

The two beauties laughed excitedly.

Because they all know that there are too many precious treasures in this world.

Build a cave here, set up a teleportation array, and you can come and go at any time. Treasure hunting is really convenient.

Zhang Bin didn't hesitate at all and directly placed a teleportation array in the most hidden corner.

He also smeared it carefully with dragon's blood, almost blending into the environment.

After all, the keel was invaded by the red mist and turned red.

"Husband, isn't dragon marrow also very precious?"

Han Bingyun asked expectantly. When Zhang Bin nodded, she said excitedly: "There must be a lot of dragon marrow in the dragon's head over there. Let's take that dragon head away and go back and find a way to break it."

, take out the dragon marrow inside."

"That's impossible."

Zhang Bin sighed.

"Why?"

Han Bingyun said in astonishment.

"Because the faucet is too big, like a mountain, and the keel is extremely heavy, no less than a mountain made of steel. You can see that the faucet is almost completely buried underground." Zhang Bin said, "There is nothing we can do with our mental strength.

Take it."

This is true, the dragon head is more than a hundred times larger than the half dragon claw he got last time.

He had to put on a hundred times the lightening charms before he could do it.

That's too hard.

And the faucet had to be dug out because the noise was too great.

This is at the foot of the mountain, near the bone dragon's lair, and it is easy to be discovered by the dragon bone.

"Then find a way to drill through the dragon bone and enter to get the dragon marrow."

Han Bingyun's mind was very flexible and he immediately changed his plan.

"Try the hardness of this keel first."

Zhang Bin took out the bloody teeth and cut them heavily on the keel.

"when……"

Sparks flew and the bloody teeth whined.

There is not even a trace of the keel.

Zhang Bin took out the Taiqing Cone that he had refined.
Chapter completed!
