Rumble......

Shan Thirteen's consciousness moved, and he looked inside the entire bone mound, and at this moment, there were bones that couldn't stop filling it, and the bone qi cyclones formed by each other were constantly squeezing, and there was a tendency to transform to a liquid state.

"Bone gas liquefaction?"

Shan 13 was very surprised, the liquefaction of true qi was a sign of the transformation from the qi training period to the foundation building period, and it seemed that he had not yet reached that step!

Obviously, no good luck came this time, these bones were only purified again at the same time as entering the bone mound, and the purity of the bones was a little viscous.

In just three weeks, the backbone qi in the bone mound reached saturation, and so far the bone qi centered on the ulna of the left arm, unfolding the Zhou Tian cycle, and a little bit of heaven and earth aura was slowly absorbed by the bone mound and slowly grew.

"Heaven-shattering lore!"

Shan Thirteen couldn't stop his excitement, and immediately turned his backbone away, and cast a sky-shaking lore, and the speed of the mini axe was three points faster than before, almost as soon as his mind moved, he was transformed in his hand.

Rumble......

Under the axe, the wall of the quiet room was split with four inches of axe marks, and the backbone qi in the body did not decrease much, it seemed that in the final stage of exertion, part of the dissipated backbone qi was absorbed by the bone mound on its own.

"Come again!"

Shan Thirteen tried happily, and finally figured out the current situation, which can completely achieve four consecutive shots, and the time for backbone recovery is shortened to less than an hour.

With the Bone Mound's Mountain Thirteen, both the speed of cultivation and the speed of recovery have risen by leaps and bounds, and the overall strength has increased by three percent.

"It's time to try the refining of bone weapons!"

Shan 13 was satisfied with the blue ribbon wrapped around the ulna of his left arm, and even took out a large number of bones from it, the shape of the ** ended, but the bone lines of each one were above seven lines.

Now that the soul fire has reached the second grade, the bone talisman does not need the beast blood as an introduction to engrave, but directly uses the soul fire to brand, so that the process is reduced and the efficiency of refining is significantly improved.

Boom......

There was a roar at both ends of the stone room for three days, and such days lasted for more than three months, and Shan Thirteen slowly opened the stone door of the meditation room, and the whole person was radiant, and he knew that something good had happened at first sight.

"Flame Wolf!"

Shan 13 came to a wasteland in the back mountain, and threw out a piece of white bone in his hand, and in the process of flying, the white bone suddenly burned, and the raging flames were like a demon wolf spitting flames, attacking towards the target.

Boom –

The target's strange flames shrank suddenly, and then rapidly expanded outward, producing an earth-shattering explosion, leaving behind a three-meter-deep hole.

"Yes, it's almost the same as a blow from a monk in the foundation building period, and it seems that we need to collect some more eight-striped bones. ”

Shan Thirteen was very satisfied with the results of the test, with the refining of the soul fire, the power of the bone talisman rose sharply, and the effect achieved by the previous nine-striped bone talisman, at this moment, the eight-striped bone talisman was not inferior.

As for the complete set of bone talismans, this is the basis for refining bone weapons, and a large-scale experiment was carried out with the thirteen mountains regardless of the loss, and finally the emperor lived up to his wishes and refined the claws of an ancient beast.

The claw was a single skeleton derived from a blue ribbon, but its hardness was second to none, and it took five days to refine it, from four feet long to the size of an adult's palm.

Qiang ......

Mountain Thirteen picked up the beast's claw and slashed it at the wall of the quiet room, splashing sparks all over the sky, and the claw marks left behind were more than two inches, similar to the sky-shattering lore of Mountain Thirteen before there was no bone mound.

"Pure power is like this!"

Shan Thirteen laughed, and a bone qi poured into the beast claw from the palm of his hand, and suddenly the beast claw was like an ancient giant beast awakening, and a fierce aura rose rapidly.

Shan Juan waved his claws and grabbed at the wall, only to hear a "boom", and the wall was grabbed into a deep hole the size of a fist, and the deep hole was surrounded by a spider's web-like crack, which stretched to the entire wall.

"Although the consumption of bone energy is amazing, it also proves the success of the refining of bone weapons, although it is a little clever in materials, but after all, it is the first bone tool that I have refined!"

The bone weapon is equivalent to the magic weapon of the cultivation realm, and it is extraordinary for ordinary people to urge it out, and the consumption of nature is extraordinary, if the strength is not enough to forcibly urge it, it is common to cause backlash, but the benefits, don't say more.

Shan 13 touched the bone weapon in his hand over and over again, thinking in his heart that if he refined a bone axe and cooperated with the Heaven Shaking Kill, then the power of this move would be absolutely unprecedented.

Where can I find the raw materials for the bone axe?

After a little thought, Shan Thirteen turned his attention to the Ecstasy Bone Touching Technique and the Phantom Bone Technique, which had been restricted by strength before, and had been shelving these two techniques highlighted in the "Bone Classics and Marrow Sutra".

Now that there is finally the possibility of further study, with the protection of the soul fire, and the soul touching technique, he is not afraid of the evil spirit and resentment of the original owner of the bone, so as to collect bone paste and bone evil to the greatest extent, and extract the remnant soul to refine bone crystal.

And with the tempering of the soul fire, the cultivation of the illusion bone technique has stepped onto a new level, and for this technique that can be transformed, Shan Thirteen still attaches more importance to it.

At first, I just wanted to refine the bones of the whole body, but I never thought that when the last bone was refined, a soul-shocking change occurred in the whole body, and a faint shadow appeared in the bone body.

"It's weird!"

The human body has a shadow, which is the effect of light, and in the final analysis it is just an abstract concept. But at this moment, the shadow that appeared in the bone body was a real invisible energy like the soul.

This has to make people worry, who knows if it will be bad for themselves in the future?

Pushing the backbone, true qi, and soul fire vigorously, even if it is consciousness, it has no effect on the shadow, and it still exists as if everything has nothing to do with it.

Shan Thirteen thought back to the before and after the appearance of this shadow, and the problem was that he had completely cultivated the Phantom Bone Technique, could it be that there was still a secret to this Phantom Bone Technique?

Shan 13 checked the records of the Phantom Bone Technique again, analyzing it word by word, only the last sentence was a little nondescript: "Heaven and earth and all things, there is no phase, the sky above the head, the feet on the stars, the illusion of disillusionment, the holy bone dharma body!"

What can be related to the Phantom Bone Technique, that is, the four words "Holy Bone Law Body", Shan Thirteen carefully pondered the connection, and seemed to think of something, but he didn't catch it.

Since it was caused by the cultivation of the Phantom Bone Technique, it was a big deal to cultivate once, which was far more than what was actually true of one's own empty thoughts. Just do it when you think of it, this is the consistent style of Shan Thirteen, which is to refine the bones again according to the illusion bone technique.

Time passed minute by minute, and this time the speed of refining bones slowed down a lot, and it was finally coming to an end. The spiritual consciousness of the whole person of Shan Thirteen is concentrated on the last bone.
