The journey up the sternum was not long, and Song Rui quickly found the source of the gray air.

What makes Song Rui entangled is that this position ...... Right at the neck bone of the bone dragon.

Song Rui remembered that when Tao Zhangmen mentioned the bone dragon, he once said that there was a puddle of blue liquid in the transparent neck bone of the bone dragon, and this liquid was probably the key to the alienation of the bone dragon's body.

But if this is the source of the gray air, then things will be complicated.

"And, how can this help?" Song Rui squatted down and carefully observed the gray air in front of him. The grey air here was completely materialized, visibility was so low that he had to get very close to see what was going on.

In front of him, there is a transparent bone, and you can vaguely see the blue liquid inside, the liquid is shrouded in gray air, and it is impossible to see clearly, but there is no doubt that this should be the location that Tao Zhangmen said. At the same time, this location is also the place where the gray air is most intense.

Song Rui's eyes were almost on the bone dragon's neck bone, but he still didn't find the source of the gray air. He looked around a few more times, carefully felt the direction of the air, and after confirming that it was here, he sat down in front of the transparent neck bone and began to think about countermeasures.

Just as Song Rui approached the bone dragon's neck bone, two more blue lights lit up in the bone dragon's eye socket.

The bone dragon didn't move, so Song Rui didn't notice anything abnormal, and the blue light in its eye sockets was not for attack, but for vigilance.

If the bone dragon had skin muscles, then it must be in a state of muscle tension now, this feeling is like a person holding a sharp knife in front of the eye, and the instinctive sense of crisis will make people involuntarily tense their muscles.

The reason why the bone dragon reacts this way is because the transparent neck bone is actually equivalent to its reverse scale, and the instinctive reaction of the body makes it involuntarily tense its nerves.

Song Rui didn't know about this, he had already discovered the source of the gray air, a drop of gray liquid floating in the blue liquid.

Because gray is a color that is easy to ignore, coupled with the influence of the heavy gray air around him, Song Rui lay on the neck bone of the bone dragon, and observed it back and forth several times before discovering the drop of liquid.

Although the gray liquid floats in the blue liquid, there is no sign of miscibility between the two, and even the gas emitted by the gray liquid does not merge into the blue liquid at all.

The volume of the liquid is not large, only about a drop the size of a thumb, not to mention the volume of the bone dragon itself, even compared to its neck bone, it is insignificant. But this small drop of liquid was so powerful that not only did the bone dragon have no way to deal with it, but the gray air it emitted was also a devastating existence, and the effect was simply terrifying.

"Chaos aura? What kind of existence is this, it has such a powerful power......" Song Rui instinctively felt that this kind of thing was very powerful, but unfortunately, he didn't know how to use it, and it is estimated that no one in this world knows how to use it.

"Anyway, now we have to find a way to get that drop out." After thinking for a long time to no avail, Song Rui decisively gave up thinking, "It is obviously not feasible to take out the broken bones, then there is only one way......"

As he spoke, Song Rui took out the Chaos Jade from his collar and approached the transparent neck bone.

"It worked!" I saw that the gray liquid seemed to be pulled by something, moving towards the direction of the Chaos Jade little by little, although the speed was very slow and slow, but Song Rui was not in a hurry, he simply lay on the neck bone, and pasted the Chaos Jade on the position of the transparent neck bone, and then waited.

Tao Ran and Ou Shi are here.

It had been nearly a whole day since Song Rui left, and the gray air still hadn't changed.

The moment Song Rui entered the gray air, Ou Shi had already lost his sense of him. When Song Rui stood in the gray air, although Ou Shi could see his figure, he couldn't sense any breath that belonged to Song Rui, and if he closed his eyes, there was nothing in front of him.

And Tao Ran also had a similar feeling, she could sense the delicious breath on Song Rui's body from the beginning, as long as Song Rui appeared within a certain distance of her, she could sense it. But after Song Rui entered the gray air, the delicious smell disappeared completely.

Compared with Ou Shi's doubts, Tao Ran confirmed that this was a good thing.

Because if you can feel the delicious breath of Song Rui, then there will be other people...... Or the beast may also feel the breath on his body, which is very unfavorable to Song Rui, Tao Ran knows that Song Rui's most cowardly thing is to be eaten, if the gray air can completely cover the breath on his body, it is equivalent to another layer of insurance for his own safety.

Time flies, and three days have passed in a blink of an eye.

Ou Shi frequently looked at the gray area, and from time to time he threw a pebble or two into it. It's already the day of the appointment, but there is still no movement in the gray air, and Song Rui, who has entered this area, is also like a stone sinking into the sea, without the slightest breath, and no sound comes out.

Compared with Ou Shi's anxiety, Tao Ran behaved very calmly, she was cooking slowly and methodically, with a steaming kettle at hand, she was going to make three-color milk tea, it was rare for Ou Shi to find an extremely rare two-color milk fruit, which was the most suitable for making milk tea. The three colors of black and white tea flow in the porcelain white teacup, the flavors complement each other, but there is no sign of blending of colors, quietly flowing and outlined in the teacup, like a landscape painting.

And Xiaobai is also squatting on Tao Ran's shoulder very leisurely, there is a spiritual connection between it and Song Rui, and he can roughly know Song Rui's state. It knows that Song Rui is not in danger now, and he doesn't even have too many ups and downs in his spirit, which shows that his father's condition is fine, as for the reason why he hasn't come out yet...... Probably because the matter hasn't been resolved yet.

In Xiaobai's world, there is nothing that his father can't solve, if there is......

Impossible!

Therefore, this baby is still in the stage of great worship of her father, and Song Rui is simply a hero-like existence in her heart. But we all know that this stage will always pass, just like the growth process of ordinary children.

"Ranran, aren't you in a hurry? Three days have passed. Ou Shi looked at Tao Ran's state and felt a little strange.

Tao Ran handed a cup of three-color milk tea to Ou Shi, and corrected him seriously: "It's not over yet, there are still ...... before Song Rui's appointment" She raised her head and glanced at the sun, "There are still about four hours to go." ”

“…… All right. Ou Shi took a sullen sip of milk tea, he didn't know why he was so irritable, it was said that the sun was just right at this time, he should find a thick tree trunk, squint his eyes and sleep.

Thinking of this, he squinted at the sun and felt even more restless.
