However...... Time passed little by little.

An hour, two hours, and then ...... Ten hours.

Lu Yu sorted out all kinds of things in his own small world, and these tasks were originally very time-consuming, and it was even more laborious than putting these things in.

So he didn't pay attention to the passage of time, and he didn't need to know, he just needed to know that the sand pool was good for his body, and the longer he could stay in it, the better it would be for his body.

So...... Later, he started building something in the small world.

For example, he came to the dragon corpse, looked at it, and then built some beautiful platforms and things like that around it, and then put it on it, and from a distance it looked like a white statue, which was very beautiful.

"Well, if you have the chance, you should have a dragon barbecue, huh...... It should be delicious, Xiao Ruan must like it very much, hehe. ”

He thought maliciously, and then looked at the golden insect next to him, it had been eaten almost, after more than a year of travel, Lu Yu took it out from time to time to add food, and it was actually only the size of a person, it would be eaten after all, and now there is really not much left.

Pouted, put it in a small box, as a treasure, if you really encounter any important situations in the future, it is better to eat it again, after all, in fact, it is also a kind of 'supplement' for Lu Yu.

Its inner pill has already been absorbed by Lu Yu's body, but its body still has some golden energy, which can partially supplement Lu Yu, and the use of golden energy at a critical moment can indeed make Lu Yu temporarily powerful.

Thinking of this, Lu Yu was suddenly stunned.

Because he thought of another question.

That's ...... In fact, there is a kind of thing that he finally obtained, but for various reasons, mainly because of his mood, he never thought of touching it or using it, and with the change of mood, this kind of thing is not so important in his heart, so he naturally forgets it.

Merely...... That's really something that can't be forgotten.

The Dragon's Inner Dan!

It was stuffed back into the dragon's body by Lu Yu before, and the huge Neidan didn't know how much energy it contained.

Lu Yu turned to look at the dragon's body, remembering that he took Neidan out of the mouth of the golden insect king, cleaned up the blood stains on it, and then prepared to use it as a treasure, but because Lu Yu's golden energy was enough at that time, coupled with a gratitude to the dragon in his heart, he didn't think of using it or anything.

Now that I think about it, what a waste I was.

Stretching out his hand, Nedan slipped out of the dragon's mouth and calmly landed on the hand of Lu Yu in the state of Divine Soul, perhaps because Lu Yu was too lacking in energy now, which made his grasp of energy more accurate, so he could clearly feel the incomparably powerful energy from this Nedan.

"Damn ......"

The excitement that Lu Yu had just raised immediately disappeared.

Because...... The power contained in this Inner Pill is simply too great!

Although the dragon itself has become extremely weak due to injuries or intentional actions of the Protoss, this does not affect the Inner Dan, which represents the strength of the dragon in its strongest period, or a state that exists in itself.

So how powerful is it, Lu Yu roughly calculated, and still thought that it had the ability to sweep across the entire continent today.

But the problem immediately arises.

This is Nedan, without the moisture of the dragon's body, it is more like an energy ball.

As soon as its surface is broken, all the energy will be released.

This means...... It's not a bottle of meat sauce with a long shelf life, you can take out a little and eat it, close the lid and throw it in the refrigerator, it's more like the kind of thing that you have to eat as long as you open the lid, and if you don't eat it all, the rest will be wasted.

And now Lu Yu's body, especially his fake golden pill, let alone absorb it all, even if it is a tenth, one hundredth, such an amount, he can't absorb it, which means that if Lu Yu uses this giant dragon inner pill now, it will be a great waste!

And Lu Yu also clearly knows that this thing has to be regarded as a big luck, and this kind of opportunity may not be able to happen again in this life.

The only Inner Dan, or is it a waste to absorb less than a thousandth of its power now, or do you keep it until you become stronger in the future, and then absorb all of its energy as much as possible?

This is a problem.

Just like life or death, this multiple-choice question that has plagued many people for countless years is also bothering Lu Yu now.

He was even a little upset, if he hadn't remembered it, it would have been a better thing.

"Pain...... Pain really comes from entanglement, and a life without choice is a happy life!"

Lu Yu smiled bitterly for a while, then put Neidan back again, sighed, and decided to withdraw from the soul state to see what kind of condition would happen to his body.

But...... At this moment, very suddenly, Lu Yu suddenly felt that the whole world was shaking.

Not too obvious, but clear enough.

Lu Yu clearly knew that this kind of shaking of the world in his body would only have something to do with one thing, that is, his body was undergoing great changes.

No matter what kind of change this is, it is not a good thing for Lu Yu.

He doesn't like too much change.

At the same time, he can also feel that his body, for some reason, is in dire need of some energy, and it needs a lot of energy to fill the void that his body needs.

It's like a balloon has a hole, and the air flows out, and if you want to maintain it, the light can't be blocked, and you have to blow air into it.

Energy is needed, but what Lu Yu lacks now is energy.

He immediately thought of the dragon's Nedan.

But...... No way!

It can't be wasted on this kind of place yet.

So......

Lu Yu's gaze was on the dragon corpse itself.

Dragon blood, dragon flesh, is the form it finally appears after countless years of cultivation, countless torments, transformations, sublimations, yes, this dragon is a thoroughly mature dragon, the dragon of the divine realm, it ...... In a way, it can also be said to be a kind of deity.

And the body of this god was placed in front of Lu Yu, and it ...... There is energy! There is plenty of energy, and it is the energy of the physical state, but it can be absorbed by Lu Yu's body that is in dire need of energy at this time than Nedan.

Thinking of this, Lu Yu directly used the Divine Soul State to cut off a large piece of flesh and blood on the dragon's body, and then used the true fire to refine the source energy, and directly transported it from the small world to fill the needs of the body.
