And outside Xie Shi's ten zhang, another even bigger cave appeared, but this cave was not horizontal, but downward, its width, more than half a mile, up and down did not know the depth, making this huge bone pillar hollow!

Similarly, the bone sword in Xie Shi's hand, its guiding power, was even more obvious, and the red light had already enveloped the entire sword body, making this sword a blood-red color.

Following the power of this guidance, Xie Shi looked at the vertical downward cavern, and there was no other abnormality except for the continuous blowing of the ice wind.

"Since I have come here, if I give up here, it is not my Xie Shi's original wish, and since this is a place to test Qi Condensing Cultivators, the danger will definitely not be too against the sky, I believe that building a foundation is already the limit, and the bone sword has changed like this, it is by no means ordinary, since my Dao heart is fighting, I naturally have to fight to the end!"

In the midst of the groaning, Xie Shi gritted his teeth tightly, slapped the spirit beast bag again, and more than ten red-blooded bees flew out again, heading straight down the cave, and at the same time, the black and white beast was also woken up by Xie Shi from his sleep and stood on his shoulder, and at the same time, in his body, the exquisite power was all turned on.

Taking a step, Xie Shi jumped down from this cave, feeling the spiritual sense imprinted on the red blood bee, and condensing all the spiritual power in his eyes and looking down.

At the same time, the bone sword in his hand bloomed with red glow, and while constantly guiding, it could turn into a monstrous sword light at any time, as long as he encountered danger, Xie Shi could unfold the eight directions at any time, forcibly float in the air, and no longer fall!

The speed of the fall became faster and faster, but unexpectedly, except for the increasingly cold wind, there was no other danger, until the distance it descended, more than thirty miles, its expression moved, and in the spiritual sense, the red-blooded bee exploring the way in front had already reached the bottom of this cave!

And what shocked Xie Shi even more was that at the bottom of that cave, there was actually an extremely rich and pure aura!

Sure enough, after descending a hundred feet again, the icy wind immediately became a lot faster, and at the same time, in its sight, a large area of gray light appeared, dazzling and dazzling, forming a thick light curtain, and at this moment, the more than ten red blood bees were flying on this light curtain, but they were not allowed to enter.

Xie Shi immediately launched the light body technique, falling like a leaf, and when he approached the light curtain, the bone sword in his hand suddenly slashed, and a crescent-like sword qi immediately flew out, and in Xie Shi's shocked gaze, the light curtain was immediately torn open a crack that was more than a foot long, Xie Shi hesitated slightly, and immediately jumped into it before the crack healed again.

And after entering the light curtain, Xie Shi's expression immediately turned into shock and shock, the aura in this light curtain was ten times purer than outside the light curtain!

And the moment Xie Shi entered this light curtain, in this light curtain, there was suddenly an endless fluorescent light, which made the surroundings immediately brighten, and suddenly Xie Shi's expression was even more shocked, under this light curtain, there was a huge plain that I didn't know how wide it was. There are no flowers and trees in this plain, only patches of yellow sand, and above these sandy soils, there are bright ice crystals, and the cold wind that stirs everywhere emanates from the ice crystals.

On top of the ice crystals and sand, there was an aura of vicissitudes that seemed to come from ancient times, which made Xie Shi suddenly feel an inexplicable sense of solemnity.

And at this point, the bone sword in Xie Shi's hand trembled to the extreme, and the red light emitted was already like thick blood, and even Xie Shi had a guess that as long as he let go, this bone sword would immediately fly out on its own!

"What the hell is this place, how can there be such a strong aura. And when the bone sword arrived, it shook to the extreme! ”

Xie Shi stood in place, his mind kept surging, and after a while, he finally gritted his teeth fiercely, let go of the hand holding the bone sword, and suddenly the bone sword turned into a scarlet streamer and went straight forward, and after Xie Shi's expression became more vigilant, he also showed his magic technique, and even used the Flying Spirit Sixteen Swords to condense the sword lotus, inspiring a hurry, and chased towards the bone sword.

I don't know how long it took, in Xie Shi's sight, a tall pitch-black altar appeared, this altar was square in shape, the size of an acre, on this altar, there were white bones, these bones were piled up in the shape of a high tower, and at the top, forming a white arm.

But the arm is not complete, but missing, and not the whole piece, but one by one, like a speck. Although the spot is small, because the arm is so large, each of these spots is the size of an ordinary person's palm. And the palm of this arm is shaped like grasping something, but at this moment, the palm of the hand is empty!

But Xie Shi knew at a glance that there must be something in this palm, but now, it is missing!

And at this moment, the bone sword, the red light has disappeared, is deeply piercing into this arm, and there is a trace of white airflow, which is absorbed from this bone tower, and quickly drills into the bone sword, and with the loss of this white airflow, the entire bone tower, at a speed visible to the naked eye, rapidly dimmed, the white bones, turned gray, and after a while, began to weathered and fell off, just like this bone tower, is being sucked away by the bone sword!

And after these white airflows were inhaled, this bone sword also changed, and the bone holes that were still faintly visible on it all disappeared at this moment, making this bone sword look like a mirror, and the original gray and white color of the bone sword was faintly golden at this moment, making this sword look sharper at the moment, and at the same time, it also had an indescribable luxury and fairy energy!

This process lasted for half an hour, and when the entire bone tower turned into ashes, and even most of it had collapsed, the bone sword finally stopped absorbing, but returned to Xie Shi in a flicker, becoming a golden bone sword!

Holding the bone sword in his hand, Xie Shi immediately felt that the bone sword at this moment was at least ten times sharper than before! Even he has the confidence that the bone sword at this moment can already directly smash the treasure weapon above the best magic weapon!

Nodding very excitedly, Xie Shi held the bone sword in his hand, and waved it cautiously to feel it, and the rumbling sound of the sword easily tearing through the air explosion suddenly made the black and white beast on his shoulder also frightened.

Satisfied, he put away the bone sword, Xie Shi looked at the bone tower again, after the bone tower collapsed, a large number of shining crystals were immediately revealed, the small ones were like fists, and the large ones were like heads, counting them carefully, there were as many as hundreds.

"This adventurous trip, sure enough, not only has the bone sword changed, but I can also get such a number of bone marrow, I believe that before long, I can use a complete set of flying swords to perform the sword formation technique!"

With a wave of one hand, all the bone marrow was put into the storage bag. Although this trip was dangerous, and even suffered a lot of losses on the guardian bone demon, but with such a gain by mistake, Xie Shi had already put aside all the previous unhappiness.

Didn't leave immediately, Xie Shi instead sat cross-legged, the sword lotus circled, guarding the surroundings at the same time, he began to carefully sort out all this, from finding this bone pillar, fighting the bone demon, followed by the cave in the bone pillar, the light mask, the spiritual power, the altar, the bone tower, the arm, between all this, there seems to be a connection that Xie Shi can't explain, this kind of call is about to come out, but there is a connection that can't be exported, which suddenly made Xie Shi have a greater interest in this place, and then his expression moved, and he patted the storage bag, Suddenly, the jade slip handed over to her by the woman of Chu Yunzong was taken out by her, pasted on her forehead, and turned into a map in her mind.

"It seems that if you want to know about it, you have to explore the other bone pillars as well, but the time for the bone demon tower to open is limited, so I don't know...... Forget it, since it has come to this point, there is no reason to give up, if there is still a harvest, I will have more weight to rescue my senior sister! ”
