If you guessed correctly, the bone dragon sent itself into its body, probably wanting to let itself help find out the source of the gray gas and eliminate it......

"So the question is, is it now looking for something in this maze of about 30 x 10 x 5 meters?" Song Rui clenched his right hand into a fist and slammed it into the palm of his left hand, "I'm familiar with this!" The maze is out of it! ”

Get! This product is also played!

"Well...... Although I think it's more reliable to go up, let's go down and take a look. Song Rui's idea is really based on the exploration method of puzzle games.

Although the bone dragon only has bones all over its body, and the entire space cannot be called occluded, the visibility around it is really not very good, and after entering the bone dragon's body, the gray air becomes thicker and thicker, and the field of vision is also compressed to a very small point.

"This is also a rare experience...... Song Rui thought bitterly, "I guess when this exploration is completed, I can be called the person who knows the most about the body structure of dragons, it sounds pretty cool!" ”

I'm afraid this is the same for the bone dragon, the dragon is a very arrogant creature, how can it be possible to allow a creature to explore in its own body at will, if any creature has such a thought, it is estimated that it will be killed by the bone dragon's claws in an instant.

Song Rui was in this environment, exploring inch by inch, because he didn't want to go back, he explored extremely carefully. Because of this, his exploration is not too fast.

As time passed, Song Rui's sense of this gray air became more acute. Putting aside the oppressive and ominous feeling that had always been with him, he was able to feel the flow of the gray air in more detail.

People's emotions have always been a major factor affecting people's perception, whether they are happy, worried, sad, or fearful, they all affect people's perception of the world. This coincides with Tao Yu's concept, and the food theory he adheres to is based on this, and it has to be said that it is also very reasonable. Many things, if you can strip out your emotions, it may be easier to discover the essence of this world, just like Song Rui is doing now.

Although he couldn't completely strip away the ominous feeling in his heart, he was able to suppress this emotion for a while and simply perceive this gray breath.

After a while, Song Rui found that there seemed to be some kind of misunderstanding in his perception of gray gas.

The first impression of gray gas, whether it is its property or color, is that it is full of ominous and death. But Song Rui has been in this gray air for a long time, and aside from the subjective factors, he found that this gray air actually has no attributes, there is not such a strong breath of death, and of course there is no breath of life, it is like an empty void, and it is like a nascent chaotic qi.

"Wait, Chaos?" Song Rui stopped suddenly, he suddenly felt that he had heard the word "chaos...... Chaos ......"

"Jade of Chaos?!"

Song Rui remembered that Jie Nai's mother-in-law had reminded him not to take off the jade around his neck, and he had asked her this question, and Jie Nai's mother-in-law said that this piece of jade was the jade of chaos.

"Jade, since ancient times, has been known as the essence of stone, and there are also known as earth relics, which is a spiritual stone with the function of driving away evil and avoiding evil." Song Rui searched carefully in his memory and confirmed that Jie Nai's mother-in-law said so at that time. And she also said that the biggest feature of the Jade of Chaos is that it has no attributes. Because of this, this piece of jade can cover the aura of the jade skeleton on his body.

"There are no attributes...... Song Rui muttered to himself, he took the jade out of his collar and held it up in front of his eyes, "The gray air can't perceive the attributes, but it's very similar to chaos." As for the ominous and oppressive breath of death I felt, it was probably the breath left behind by the animals and plants that had been devoured by life......"

Even if a creature dies completely, its breath will not disappear instantly, but will remain for a period of time, which does not refer to some theories of gods and ghosts, but refers to the remnants of its subtle breath. For example, after a person dies, the breath of the things he has used will remain for a long time. And the death of a large number of lives, the residual breath, is about this kind of ominous and oppressive breath of death.

"So the breath of death is not an attribute of gray air, and gray air doesn't actually have any attributes? Could it be the vaporized state of the Jade of Chaos? Song Rui carefully felt the gray air again, and sure enough, except for the dead air, he didn't perceive any attributes.

"If the gray air is chaotic qi, what kind of reaction should it have with the jade of chaos...... Wait a minute! Although Song Rui held the jade in front of him, he was thinking about other things in his heart, and his eyes did not fall on the jade at all.

"In other words, I can enter this space, not because of the difference in my own life form, but because of the existence of this piece of jade?" He pinched his chin and thought for a long time, then asked himself, "It seems that it is right, but what is the reason why the bone dragon is intact?" And this piece of jade ...... Hey?! ”

Song Rui finally set his eyes on the jade in front of him, and finally found the abnormality in the jade. This reflects the arc...... Forget it, we all know that we don't bother to complain.

The Jade of Chaos originally had a thin line of blood inside, and it swam in the jade like a living thing. Song Rui recalled, and determined that the speed of this blood line was now significantly faster, and it seemed to be thicker than before, although it was very inconspicuous, but ...... It shouldn't be an illusion.

The surrounding gray air also seemed to react to the appearance of the Chaos Jade. I saw that after the air around the jade tumbled for a while, it actually approached the location of the Chaos Jade, and then turned into wisps of mist and merged into the jade.

This process is not going fast, but it cannot be stopped, even if Song Rui holds the jade in the palm of his hand, the process continues. The Jade of Chaos was like an elegant aristocrat dining, completely unaffected by any factors, slowly devouring the gray air around it little by little. The gray air didn't resist in the slightest, and even consciously gathered a little towards the Chaos Jade.

"En......" Song Rui thought for a long time and felt that this should not be a bad thing. Then again, even if it's a bad thing, he doesn't have the ability to stop it now, so it's better to go with the flow.

After such a toss, half a day has passed, and Song Rui's exploration has also reached the position of the belly of the bone dragon.

The bone dragon was still motionless like a sculpture, and he didn't care about Song Rui, as if he had let go of himself, and let Song Rui play.

Song Rui took a second to reflect on his procrastination, and then walked unhurriedly towards the tail of the bone dragon.

Of course, thanks to a second of reflection, this time he sped up a little, and soon explored the position below the sternum of the bone dragon.

"Well...... As I expected, is the source above? Song Rui said a very bad nonsense, and Shi Shiran walked towards the head of the bone dragon.
