this……

When Zheng Tuo heard what the old man said, he really didn't know what to say.

Too.

At such an old age, it is normal to be incapable.

No, no.

Zheng Tuo shook his head, what was he thinking?

The old man is also an immortal cultivator. The ability he is talking about should be that his own strength level is not enough to refine the immortal essence.

Thinking about it carefully, Zheng Tuo can completely understand.

Immortal marrow is an extremely precious thing, and in the entire world of immortal cultivation, the ball of immortal marrow in front of him may be the only one.

It stands to reason.

A strong person in the out-of-body stage can completely refine and harvest immortal marrow of ten thousand years, one hundred thousand years, and one million years for his own use.

But according to what the old man said, the fairy marrow in front of me is hundreds of millions of years old, and it can be called the king of fairy marrow.

It is completely understandable that the old man in front of me cannot refine it.

I am afraid.

A billion-year-old immortal marrow, even a half-immortal like the Lord of the Shadow Demon cannot refine it.

"So, old man, what you mean is..."

Zheng Tuo sharply noticed something was wrong.

This old man looks like he is about to live a long life, but who knows if he is actually faking it.

"Don't be nervous, little friend. I don't have any ill intentions, it's just..."

The old man looked at Zheng Tuo, "It's just that I feel that my little friend seems to have a special power. The level of this special power is actually higher than the billion-year-old fairy marrow, so... I want to ask my little friend for help.

, help me refine some immortal marrow to extend my life."

The old man said it very sincerely, but when Zheng Tuo heard it, he immediately became extremely vigilant.

This old man had two brushes, and he actually felt the existence of the mark of heaven.

Sure enough, none of the old things are fuel-efficient lamps.

"this……"

Zheng Tuo hesitated and thought about countermeasures.

"I know my little friend is in trouble."

The old man was in a low mood: "I believe that my little friend has felt the death energy emanating from my body. To be honest, I don't have much life left. If I hadn't practiced beside the immortal marrow these years and absorbed the energy of the immortal marrow, I would have died long ago."

Transformation. Originally, I no longer had any hope that there would be no one who could refine the billions of years of immortal marrow in the Immortal Realm of Nuo Da Xiu, but..."

The old man looked at Zheng Tuo, and a star-like light slowly gathered in his eyes.

"But I never expected that such a talented person as my little friend would appear in the world of immortal cultivation. Your power level is extremely high, which I have only seen in my life. I believe that with my little friend's strength, I can completely refine the immortal essence."

The light shining like stars in the old man's eyes became brighter and brighter.

That is the light of hope.

That's right, it's definitely the light of hope.

"Please rest assured, little friend, I only need a ray of refined fairy marrow to continue my life to fulfill my unfinished wishes. As for the remaining hundreds of millions of years of fairy marrow, all of them belong to you. And if you don't believe me, old man, I

, old man, I can swear..."

The old man's words were a little fierce.

He looked excited, like someone struggling hard after seeing hope.

Zheng Tuo didn't speak. He was thinking about whether what the old man said was true or false.

The old man couldn't wait to swear that it would not be harmful to Zheng Tuo. At the same time, he only needed a ray of fairy marrow to survive, and he would not compete with Zheng Tuo for the remaining fairy marrow.

Zheng Tuo felt a ray of heavenly vow coming.

That is to say.

There is nothing wrong with the old man's oath and it has come into effect.

Zheng Tuo still believes in the oath of heaven.

Unless the opponent is half-immortal in strength, he will definitely be restricted by the oath of heaven.

anyway.

If the opponent was a semi-immortal, he would probably have taken away his body long ago, and then used the mark of heaven to start refining the billion-year-old immortal marrow.

After thinking about the pros and cons, Zheng Tuo finally decided to see if the fairy essence was true or false.

Wouldn't it be too embarrassing to look back and realize that the immortal essence is fake now?

"Old man, please wait a moment and let me see what this fairy marrow is saying first."

Then.

In the old man's shocked eyes, Zheng Tuo took out a complete set of hundreds of experimental puppets from the Qiankun Bag.

Hundreds of experimental puppets have professional techniques, complete tools, and a wide range of knowledge.

The meaning of their existence is to help Zheng Tuo distinguish the authenticity of various messy substances.

Spiritual objects, magic weapons, gender...all are invisible under their professional techniques.

The experimental puppets used their skilled technology to start testing the billion-year-old fairy marrow.

"Little friend, what are you doing?"

The old man admitted that he had seen many strange and strange things.

But today was the first time he saw him like this.

Who would carry so many special puppets with them for nothing?

"It's okay, the old man just needs to wait for a while."

Zheng Tuo said he was fine on the surface, but he was secretly vigilant in his heart.

The experimental puppet inspection was very fast, and in just a moment, the first wave of information was collected.

After getting the results, Zheng Tuo knew that his vigilance was right.

Because the football field-sized ball in front of you, like a small sun, is not an immortal marrow at all, let alone a billion-year-old immortal marrow.

According to the experimental puppet test, the ball is the result of some kind of natural imprint.

The grade is far from the Seal of Heaven, let alone on par with the Seal of Heaven.

"Old man, is this...really the billion-year-old immortal essence?"

There was a sense of inquiry in Zheng Tuo's words.

"My friend, don't get me wrong."

The old man was as steady as a rock, without any panic.

"Of course this thing is not a billion-year-old fairy marrow. In fact, this thing is protected by my own power. The real billion-year-old fairy marrow is protected by me. If you don't believe it, look at it."

The old man said and waved his palm.

Suddenly.

In front of me, a small sun-like ball opened a portal.

Through the portal.

Zheng Tuo could completely see the center of the ball, where there was a ball the size of a water tank, emitting colorful brilliance.

The power emanating from the sphere was received by Zheng Tuo through the portal.

Um.

That's the taste.

Zheng Tuo's heart moved, and the mark of heaven in his body gave a vigilant reaction.

As the old man said.

The ball that is the size of a water tank and emits light of various colors is the billion-year-old fairy marrow.

Zheng Tuo looked at the billion-year-old immortal marrow, and inexplicably, a look of greed appeared in his eyes.

The size of a billion-year-old immortal marrow water tank, the whole body is like glass, emitting light of various colors.

The light was extremely warm, and at such a distance, he could feel that both his body and soul felt comfortable due to the illumination of that light.

at the same time.

There seems to be a looming river around the billion-year-old fairy marrow.
