Chapter 639 Dragon Bone

"How much essence can this dragon ball be exchanged for?"

In the hands of others, this dragon ball may be the basis of immortality, but Ning Tianlin only wants to exchange it for essence, because he has already achieved immortality. As long as it is not caused by external forces, he can live for thousands of years.

And don't worry about the end of his life!

Now, he just wants to know how much essence this dragon ball can be exchanged for, so that he may be able to greatly increase his combat power in a short period of time.

"Ten million!"

The answer of the combat power system soon sounded in Ning Tianlin's ears, which shocked him, "Ten million!"

"Ten million points of essence!"

Although this value is still a little different from what he imagined, it is almost the same. With these ten million points of essence, he can successfully practice the Yijinjing!

It can also be upgraded several more levels!

At that time, his combat power will definitely have a qualitative leap!

"Exchange!"

"Help me exchange this dragon ball!"

Ning Tianlin did not hesitate and directly asked the combat power system to exchange the dragon ball for essence, but to his surprise, the combat power system did not do it immediately, but advised, "You'd better not be so anxious!"

"Because it won't be long before this dragon ball will be of great use to you!"

"Huh?" Ning Tianlin was stunned, a little confused, "Why? What does it mean?"

This is almost the first time that the combat power system has said such a thing to him. In the past, it said that it could not be exchanged, which meant that it would depreciate here and he had to keep it for himself. But now, it directly told him that it would not be long before this dragon ball would be of great use!

"It doesn't mean anything." The combat power system said, "I just advise you to keep it first. When the time comes, it's up to you to decide whether to use it or exchange it."

"This..." The combat power system said this, he would definitely not exchange it again. After all, Xing Zhan had never said anything unreliable to him. Could it be that something big would happen after a while?

However, Ning Tianlin's combat power is low now, and his divine sense can't cover the entire earth at all. Otherwise, he would know that the big event mentioned by the combat power system is closely related to a black creature more than 50 meters long galloping on the bottom of the Indian Ocean.

This black creature is covered with scales, with two tumors on its head, which seems to be a pair of horns that have not grown out, and there are four short legs under the abdomen of its long body, each with five claws.

Behind the body, there is also a long tail.

In an instant, it passed through the sea water, bringing up a ripple, as if dragging a long tail.

"Okay."

"Then put it in the space ring first."

Ning Tianlin knew that everything the combat power system did was for himself. He dissuaded himself, which would definitely not do him any harm. Moreover, although he did not exchange it now, it was in the space ring, which meant that 10 million points of essence were always under his control.

If he wanted to exchange it, he could do it at any time.

"Where is the dragon body?"

"Where is the dragon body of this ice dragon?"

Ning Tianlin just heard the combat system mention that the dragon body was finally buried with Ge Hong's body. It is estimated that Ge Hong was planning to take the dragon body after his death.

Now, I don't know what it looks like.

Wow!

As soon as Ning Tianlin finished speaking, a green light curtain appeared in front of him. On it was the location of the cave where he was now, including the passage where he was standing in the cave, and the rolling magma below.

However, this green light curtain also had two red dots and a red square, which looked like a door, opposite the magma below.

"Could it be?"

Ning Tianlin narrowed his eyes, and in an instant, he set his sights on the physical position corresponding to the red dots of the green light curtain. There were two extremely small gaps there. If you don't pay attention, it will be like a small crack on the mountain wall.

It will not attract anyone's attention at all.

And the door represented by the red square is in the center of these two small cracks!

"Exchange for jade pendants!"

Ning Tianlin did not hesitate and directly spent 300 points of energy to exchange for two jade pendants. The appearance of the jade pendant held in his left hand was exactly the same as the soul-locking jade held by the descendant of the Ge family when he returned from the United States and met at the airport!

At that time, he returned the jade pendant to the descendant of Ge Hong because the jade pendant they regarded as a treasure was actually nothing to him! It was easy to get! He knew at that time that this jade pendant was a mechanism to open Ge Hong's tomb!

But the jade pendant in his right hand was not even owned by the descendant of the Ge family. The real jade pendant had long been lost in the long river of history.

"Shua!"

"Shua!"

With a flick of his wrist, the two jade pendants flew through the air and were accurately inserted into the two gaps. Then, the sound of the stone wall shaking began to sound in the cave.

Ning Tianlin even noticed that stones had begun to fall from the door-shaped position indicated by the red square just now.

In a moment, a stone door protruded from the mountain wall and then fell into the rolling magma.

"It seems that this is it!"

Ning Tianlin smiled lightly. As expected, it was here. And just now he knew that if he used the Thousand Fires Burning Heaven Halberd, he could directly blast open the stone door without even spending his energy.

But he didn't do it.

Because he was not sure what was behind the stone door. If he used too much force, he might hurt the things behind it, which would not be worth the loss.

He also wanted to see what the body of the ice dragon looked like.

"Whoosh!"

Without thinking too much, he soared into the air, flew through the rolling magma, and then landed at the stone door, and walked in with a click.

"Huh!"

"Huh!"

As soon as he stepped in, the rows of long-burning oil lamps on the stone wall lit up directly. This was the first time Ning Tianlin had seen such a situation, but he also knew that it was because of the air flow that activated the burning point of the lamp oil.

"It seems that this is Ge Hong's tomb!"

The tomb is not big, to be more precise, it is just a stone cave, and it is a stone cave that can be seen at a glance. Ning Tianlin has even seen that there is a low stone platform right in front of him.

A skeleton is sitting cross-legged on a futon, and the clothes on his body are also tattered and have not been completely weathered.

"It seems that this skeleton is Ge Hong!"

Ning Tianlin's eyes did not linger for too long, because soon, his attention was all on a piece of skeleton under the stone platform.

These skeletons are scattered, some are big and some are small, but if you look closely, you will find that these skeletons themselves are all emitting a cold and icy aura, smooth as jade, and they are entangled like a living dragon!
