Jiang Baiyu, who was covering his nose, was stunned, and all of them turned into ashes, how could something still fall out and smash it loudly? Looking down, he saw a small box with a cube, the box was made of no material, it was extremely cold, exuding a cold air that was not weak, even after so many years, it was still slowly exuding a chill.

Jiang Baiyu was stunned for a moment, and was slightly surprised: "I'm a good girl, shouldn't it be a cold spirit crystal?" The cold spirit crystal is a crystal produced in an extremely cold area, containing extreme coldness.

Normal cold spirit crystal, even the power of the soul can not penetrate, and even accidentally freeze the soul, directly freezing the person from the soul, and if you touch it with your hands, it is no different from looking for death, it can be frozen into ice slag in an instant, this thing is not very common in the previous life, Jiang Baiyu had one, which was used to refrigerate things.

Although the Cold Spirit Crystal is of little use, his extreme coldness can freeze things and resist the invasion of the outside world with cold air, and many times, it is used to preserve precious things for a long time.

The current cold spirit crystal, after a long period of wear, has long been no longer extremely cold, just a little colder than ordinary ice cubes, otherwise, let the complete cold spirit crystal fall in this basement, the entire basement will be frozen, not only that, even the underwater passage will all turn into incomparably hard ice, at that time, Jiang Baiyu will be tragic.

Picking it up with his hand and weighing it in the palm of his hand, Jiang Baiyu's eyes flashed: "From the perspective of weight, there should be something preserved inside, and it must not be a mortal thing if it can be preserved by the Cold Spirit Crystal, the only pity is that in recent decades." The Cold Spirit Crystal is no different from ordinary ice cubes, I'm afraid these decades. The contents have been damaged to varying degrees, and I don't know what to do. Is there anything else in it that can be used? ”

With a hint of anticipation, Jiang Baiyu began to melt the cold spirit crystal with flames, and the cold spirit crystal, which was reduced to an ordinary ice cube, did not last long, and began to melt after a while, revealing a piece of pitch-black bone that had been preserved for hundreds of years, which made Jiang Baiyu look puzzled, with such a precious cold spirit crystal, it was actually just to save a piece of bone?

With doubts, Jiang Baiyu melted patiently. Until the last trace of cold crystallized into water vapor, a complete bone appeared in Jiang Bai's palm.

The bones are only ten centimeters long, pitch black, a bit like metal, the texture is very hard, and the bone joints on it are presented side by side, and it is easy to distinguish that this seems to be the vertebrae of some kind of demon beast, and it is the vertebrae at the most important skull.

Turn the amputated vertebrae over and over again. Jiang Baiyu didn't think there was anything strange about this vertebrae, but since this thing was preserved by people at any cost, it was unlikely to be an ordinary thing.

After thinking about it again and again, Jiang Baiyu set his eyes on its cross-section. Upon closer inspection, it was revealed that there was an extremely small cut in the cross-section. It was artificially cut. With a movement in his heart, Jiang Baiyu writhed gently along the subtle cuts. Suddenly, I saw the facet. Like a bottle cap, it was slowly unscrewed!

Jiang Baiyu's heart was secretly tightened, there was really a problem, this vertebra was slightly refined, and it became the existence of a container, and the cross-section was made into a rotating bottle cap, the bone heart of the vertebrae, maybe something existed.

Carefully twisted the cap of the bottle, the pitch-black vertebrae cut suddenly emitted a ray of colorful light, illuminating the dark secret room colorfully, extremely dazzling, Jiang Baiyu couldn't help but squint, this color was too dazzling, it was not easy to adapt to this dazzling light, and after a closer look, it was found that the inside of this vertebra was hollow, filled with colorful liquid, and the liquid exuded a pure fragrance, smelling Jiang Baiyu felt that there was a trace of cultivation improvement, this scared Jiang Baiyu, smelling a mouthful can affect cultivation, what is this？

Even Jiang Baiyu had never seen such a strange liquid, and as he was thinking about it, he suddenly found that in the colorful liquid, there was a jade needle immersed in it. Jiang Baiyu carefully took it out, spread it in the palm of his hand, and after a closer look, he found that there was a tiny font engraved on the jade needle, and the handwriting was too small for idlers to see clearly.

Jiang Baiyu had to use the power of the origin of the wind to strengthen his facial features, so that he could vaguely identify the three biggest words on it: "Heavenly Dragon Marrow".

The three words of Tianlong pith made Jiang Baiyu a little surprised: "Tianlong pith? Could it be that these colorful liquids are the spinal cord of Tianlong?"

Tianlong, it sounds like a dragon, but it may not be a real dragon, as far as Jiang Baiyu understands, there may not be a dragon in this world, usually the dragon, most of them are giant snakes, through evolution, the body evolves towards the appearance of a dragon, and it is called a dragon, this dragon is mostly a kind of cherished giant snake, but unfortunately, I have never heard of it, I don't know what kind of snake Lu Dao belongs to, after all, snakes are also divided into bloodlines, noble bloodline snakes, talented, low-level snakes are the most common earth snakes, and they don't even have the qualifications to become demon beasts.

Immediately afterwards, Jiang Baiyu continued to look at the smaller font below, almost every word he had to work hard to identify to confirm, only two hundred words, but Jiang Baiyu read it for half an hour!

After reading it, Jiang Baiyu's eyes were extremely sour, he rubbed it vigorously, shook his stunned head, and looked tired, but his expression revealed a touch of excitement, deep excitement, and couldn't help but murmur: "I didn't expect it, I really didn't expect it, this is actually a rumored sonic mystical technique!"

Jiang Baiyu's face was filled with a thick sense of excitement: "Sonic Mystery Technique is a scarce product in the scarce Mystery Technique, it is almost a rumored existence, the Xuan Shi World is only circulated, and it is rare to see anyone really cultivate, even in the previous life, I have only seen it twice, I didn't expect to see one here!"

Judging from the records on the jade needle, this sonic mystical technique is called "Heavenly Dragon Roar", which is a second-order intermediate mystical technique, which is just suitable for the cultivation of Jiang Baiyu in the third layer of the sea gathering, and the occult technique can be used as a group attack type mystic technique or a single attack type mystical technique according to the user's on-the-spot play, and the power is very strong.

If the cultivation is complete, with Jiang Baiyu's cultivation of the third layer of the Juhai, under the roar of the Heavenly Dragon, the violent sound waves will shatter the eardrums of the same level, and those who cultivate below the Juhai can directly be shocked alive by the roar of the Heavenly Dragon and die of the heart!

This is the reason why Jiang Baiyu is excited, the world's rare sonic mystical technique, but there is actually a hidden article here.

It's a blessing in disguise, if he hadn't been forced here by Second Sister Liu's flaming arrows, he wouldn't have gotten this spatial ring, let alone this Heavenly Dragon Marrow and Heavenly Dragon Roaring Mysterious Technique.

Gradually converging his joy, Jiang Baiyu immediately sat down cross-legged, at present, the first task is to recover from the injury, and he fought hard with Jun Wushuang, and was injured by the flame arrows of Second Sister Liu one after another, and the injuries in his body were about to become seriously injured if he didn't take time to deal with them.

Pranayama meditated, Jiang Baiyu quickly entered a state of concentration, allowing the injured parts of his body to slowly repair on his own.

This pranayama was three days and three nights, and Jiang Baiyu's face was getting better and better day by day, until he suddenly opened his eyes three days later, his face returned to ruddy, his breath was also very stable, and his injuries were all recovered within three days.

"Whew!" Jiang Baiyu exhaled, moved his body slightly, and there was a crackling sound all over his body: "It's finally recovered, I'll wait to settle this account!"

With a cold gaze, Jiang Baiyu took out the black bone, this is the vertebrae of Tianlong, and the colorful liquid is Tianlong's spinal fluid, which has a high energy, such a piece of liquid, even if the fetal breath is strong, it can break through a level, which can be said to be extremely precious.

However, just as Jiang Baiyu was worried, during the time that the Heavenly Dragon Essence was preserved by the Cold Spirit Crystal, in the past few decades, the Cold Spirit Crystal had lost its protective effect, causing the energy of the Heavenly Dragon Essence to be dissipated quite a lot, leaving only less than one-tenth of the original energy.

But Rao is like this, with the power of the energy contained in the Heavenly Dragon Marrow, it is enough for Jiang Baiyu to break through to a level in the realm of gathering seas.

"According to what is said on the jade needle, to practice the sonic arcane technique of the Heavenly Dragon Roar, you must swallow the Heavenly Dragon Pulp and transform the throat with the Heavenly Dragon Pulp, otherwise with the human throat, the roar that can only be sent out by the Heavenly Dragon for a long time will be broken, and the voice will be lost at the lightest, and the life will be lost at the worst, so you have to pay attention to it. Jiang Baiyu was a little dignified.

But now that the opportunity to rise again is in front of him, of course he will not let it go.

Sitting cross-legged again, taking a deep breath, Jiang Baiyu raised his head and swallowed this piece of Heavenly Dragon Marrow.

Although the heavenly dragon pith smelled quite fragrant, but when it really came to the mouth, there was a disgusting fishy smell, as well as a thick bitterness, Jiang Baiyu was not wary, and almost squirted out, but fortunately he endured it and swallowed it with discomfort. These Heavenly Dragon Marrow, most of them have entered the blood veins, as the blood vessels moisten all parts of the body, a small part stays in the throat, slowly penetrating into his throat, this is a process of transformation, strengthening Jiang Baiyu's throat, so that when cultivating the Heavenly Dragon Roar, he will not roar to death first.

This process of strengthening was also extremely uncomfortable, Jiang Baiyu felt that there seemed to be thousands of ants crawling in his throat, itching and hurting for a while, back and forth, making people suffer a lot.

And the Heavenly Dragon Marrow that entered the blood veins was also extremely uncomfortable, and the places where it flowed were as if they had been lightly pricked by a needle, causing many body parts to tremble uncontrollably.

"The spinal fluid of the demon beast is really not suitable for human consumption, and only the strong body of the demon beast can easily bear it, and it is very guilty for human beings. The corners of Jiang Baiyu's mouth twitched, silently enduring the effect of the Heavenly Dragon Marrow on the body.

This process was very long, Jiang Baiyu broke through with the Colorful Bell Spirit Liquid, and it only took three hours, but with the Heavenly Dragon Marrow, it took two whole days! The human body's ability to absorb the spinal cord of the demon beast was really too poor.

After two days and two nights, Rao is Jiang Baiyu was a little mentally broken, his eyes were black, listless, and his face was slightly pale, until there was a sound in his mind, and a large amount of surrounding Xuan Qi surged towards Jiang Baiyu's gathering sea, and the feeling of acupuncture in the blood vessels of the dragon marrow slowly dissipated.

Break through! Gather the fourth layer of the sea!

At this moment, in addition to the fact that his throat was still uncomfortable and abnormal, his body had returned to normal, and the unusually thick Xuan Qi and the new sense of strength and strength all gave Jiang Baiyu a lot of surprises. (To be continued......)
