The source crystal is the product of the crystallization of the aura of heaven and earth, and the process is extremely complicated. It often takes tens of thousands of years to inoculate a source crystal.

Moreover, after the source crystal is generated, a layer of crystal shell like a stone coat will be formed on the surface. This layer of crystal shell is extremely tough. Generally speaking, only a monk who has reached the realm of Fen yuan can have his magic power enough to break this layer of crystal shell.

Meng Ran has just broken this layer of crystal shell with the help of the unique skills of the famous star power in the eternal ice field.

At this moment, the mana in Meng Ran's body was empty. This one, instantly drained all the mana in Meng Ran's Qi mansion, and there was no trace left.

Just kill that pair of brothers and sisters of a finger, Meng Ran has not yet used all his strength, and at this time in order to break open the crystal shell, Meng Ran is full play.

"The ice emperor's move is too costly."

If let that famous star of ice emperor hear Meng Ran's words, estimate gas must vomit several jin old blood.

At that time, the ice emperor used this form, directly frozen a galaxy of stars, and even frozen it for thousands of years. At that time, many of the world's most powerful people surrendered to the ice emperor.

At the moment, this unique form is used by Meng ran to break the crystal shell

It's really hard to say.

Meng ran, who walked to the stone table, looked at the four source crystals in front of her, and slowly rubbed these precious treasures only in the immortal cultivation world with her white palm. She thought for a moment.

In principle, according to the aura level of the earth, it is absolutely impossible to breed such treasures.

The source crystal is precious in the immortal cultivation world. Only the top-level aura holy land can have such a glimmer of hope for the birth of Yuanjing.

In this way, the four source crystals must have been left by the practitioners of Outland!

"Wait! The feeling just now was... "

Meng ran rubbed the smallest, but the palm size of the source crystal, the palm was as if it was electrostatic, it was a kind of crisp and numb feeling.

At the same time, Meng Ran's mind is a voice.

"Yiya..."

"This is Living things! " At this moment, Rao is too much to resist the shock of xianzun, just because the scene in front of me has never been similar!

this is almost as like as two peas of the original blood of the monk in the Yao Chi shrine.

"Are these four source crystals not for cultivation? Are their real uses Seal

Forced to suppress the shock of the heart, Meng Ran's hands were printed, sitting on the ground, it was to practice.

One side of Fang Qingchuan is still kneeling on the ground, carefully looking at Meng ran, although full of doubts, but also at least dare not speak out.

After about ten minutes, Meng ran, who had recovered a trace of mana, suddenly opened his eyes.

I saw the twinkling of the eyes, as if a ray of electric light bloomed, and directly penetrated the stone the size of a palm!

As you can see, the pure and holy source crystal center without any impurity is actually a wisp of frost white flame beating!

"This is It's frost and cold flame! "

But in the frost white flames, a figure of thumb length, curled up among them, head to tail connected, silent sleep.

Meng ran did not have time to see the shape of the figure. The flame in Yuanjing seemed to be alive. It seemed that he had been provoked. It was a "miso" that leaped up and blazed fiercely.

Meng ran only felt that this wisp of flame seems to break open source crystal to burst out in general.

Just a glance, Meng Ran's eyes suddenly feel burned by the flame, burning pain, more see Meng Ran's corner of the eye is actually out of two lines of blood and tears!

Meng ran, who had guessed what the white flame was, didn't dare to make it big. He quickly moved his eyes away from the source crystal and stabilized his mind. He ran up the "ethereal and empty formula" to counteract the burning of the white flame on his eyes.

This time, it took Meng ran nearly two hours.

After two hours, the horror of Meng ran disappeared.

"The frost and cold flame in the sky, I can't believe that it can meet the fourth fierce flame on earth. It's said that the frost cold flame is the ancient sacred beast, and the inheritance of the holy flame of dragon and horse. In this way, the living creatures protected in the fire are the Dragon and horse."

According to ancient records, there are ten kinds of flames in the universe, but the number one flame is rootless and passive. Since ancient times, only a few people have seen it.

In the last life, Meng ran, who was famous for Xuangong, once saw the immortal flame which was said to have burned and robbed xianzun in the deepest part of the endless fire field!

At that time, what Meng ran saw was a small tree half a meter high. It was not high, like a dragon lying on its branches. On its branches, there were mysterious runes circulating, which seemed to burn down all the heaven and earth.

Meng ran, who has broken Xu Shen Tong, saw clearly the essence of this tree seedling. It is a flame beating!

At that time, Meng ran, who had just set foot in the realm of xianzun, felt numb in his scalp, and felt that his immortal body would be burned.Compared with the immortal flame, the frost white flame in the source crystal at the moment is not so terrible.

Of course, not today's Meng ran can touch!
