At this time, Xie Shi was unable to immediately launch the third teleportation, and with a pat of the storage bag, a small bronze bell flew out, turning into a huge bronze bell phantom, protecting it in it, and at the same time, between Xie Shi's hands, more than ten top-grade flying swords flew out, heading straight for the tail of the bone demon, and when they were about to collide, the aura suddenly appeared, and more than ten high-grade flying swords directly exploded!

And after that, Xie Shi was even more moved, behind him, more than ten layers of talisman masks of different colors appeared, and then he no longer paid attention to the tail of the bone demon, but slapped his chest, and when he spurted out a mouthful of blood, he forcibly lifted the Bafang Fengyun step, and then re-unfolded, so that the floating power that was about to disappear appeared again, and went straight to the bone pillar in a step!

The roar echoed, and the power of the self-explosion of more than ten high-grade flying swords suddenly unfolded, and it rolled upside down, and in an instant, a dazzling wave of qi rolled out all around, in this wave of air, Xie Shi spurted blood again, the phantom of the bronze bell dissipated, and it turned into a bronze bell again, and more than ten talisman spirit shields collapsed together.

But he himself, with the help of this impact, came to the edge of the bone pillar!

But the next moment, there was an earth-shattering roar in his eyes, and he scolded without hesitation.

"Damn it!"

At the moment when it was about to touch the bone pillar, around the latter, a white glow suddenly erupted, this glow was extremely dazzling, containing endless coldness, and at the moment it appeared, a shield was formed, and this bone pillar was protected in it, and this shield was extremely strong, even the bone sword in Xie Shi's hand could not be cut off immediately!

"Damn it!"

Xie Shi scolded again, not caring about anything else, and when he turned around, he suddenly saw that the hundred-zhang bone puppet that he had cultivated with great difficulty had actually shattered under the claw of the bone demon, and became a large scattered skeleton.

And after the bone demon, the three hundred zhang bone tail that was almost destroyed by more than ten high-grade flying swords exploded, and suddenly swept away, and those scattered bones immediately rolled back and were absorbed by this tail, making this tail recover instantly, and it was unprecedented, reaching five hundred zhang!

Under the curling of this giant tail, the heavens and the earth immediately roared, and it rolled straight towards Xie Shi, and before it came, there was already endless coercion, making Xie Shi's mouth spurt blood again!

"Damn, this bone demon is not a half-step foundation building at all, but a real foundation building cultivation!"

Xie Shi's eyes showed ruthlessness, and his heart was even more shocked, but at this moment, there was no way out, his mind moved, and he slapped the storage bag again without hesitation, and suddenly ten flying swords flew out of his storage bag.

These flying swords are the best magic weapons!

With a slight click, suddenly these superb flying swordfish swam out and went straight to the tail of the bone demon that swept over, as if they were about to tear the void, and once again, they exploded!

And after that, Xie Shi once again pointed the sword lotus behind him, and the whole person stood in the center of the sword lotus, in which the lotus heart sword qi condensed, it was suddenly enveloped, and at the same time, he slapped the bone sword in his palm, and suddenly a white sword qi erupted, and at the same time, Xie Shi stretched out his finger and pointed out seven times in succession out of thin air, and suddenly the endless spiritual power around him gathered, making the bone sword sword qi skyrocket to nearly five zhang, and when the power of the sword lotus exploded, together with Xie Shi, it suddenly descended outside the bone pillar, and the white shield flashed at this moment!

The next moment, the shield suddenly trembled, and finally shattered in the Lotus Heart Sword Qi and the Bone Sword Might, along with the Seven Star Dazzling Sword Technique, and finally shattered, revealing a human-sized crack.

Xie Shi didn't pay attention to the self-explosion of the best flying sword behind him, and in the middle of his steps, he directly passed through the crack, and the bone sword in his hand was raised again, and suddenly a sword qi was excited again, and in the midst of the bang, the hole on the bone pillar was torn to the size of one zhang, and the sixteen flying spirit swords behind Xie Shi flashed together, and at the same time, the speed skyrocketed, and they stepped into this hole!

After entering, Xie Shi spurted out a mouthful of blood again, and while looking back to confirm that the white shield was closed again, he sat cross-legged without hesitation, swallowed several pills one after another, and began to heal.

As for the bone demon, after the self-explosion of the best flying sword, he re-condensed the demon tail for the second time, and let out an angry roar from his mouth, and the eyes turned into green mist stared at the cave that was split by Xie Shi, and the huge bone wings turned into a white phantom, and rushed straight towards Xie Shi.

But at the moment when it was about to touch the bone pillar, the shield that had never appeared when it first climbed the bone pillar actually reappeared, and the moment it was hit by this bone demon, the latter was immediately blocked out, and the huge impact made this demon fall countless bones all over his body, but this demon was not afraid and launched a violent impact again.

It wasn't until more than ten years later, the body of this bone demon had been shattered by a small half, and the white shield was still not damaged in the slightest, this demon gave up, but still spread its wings, flying and hovering at the entrance of this cave, staring at Xie Shi with both eyes, the green mist rolling, and the sound of hissing broke out.

Half an hour later, Xie Shi opened his eyes and looked at the bone demon who was blocked at the moment, as well as the bone golem that was already left with a pile of bones, and a large number of flying sword fragments scattered after the self-explosion, and his face showed a look of pain, he never thought that in order to obtain the bone marrow, he would spend such a huge price.

Stretching out his hand, not far away, a scattered spar fell into the palm of his hand, this bone marrow was the size of a copper coin, which was completely insufficient to compensate for the loss of the flying sword, as for the other spars, they still did not know where they fell when they tore open this hole.

But after a while, Xie Shi gathered his mind, the bone sword appeared again, and between the flashes of sword light, he began to dig along the initial hole of the size of the foot, which was also what he had just discovered, this seemingly narrow hole, but it extended to the center of the bone pillar I don't know how far, and even among them, there was a wisp of cold wind blowing out, whining sound, making this hole full of mystery.

And in the process of excavation, Xie Shi soon found that the bones in this bone pillar were much harder than the large bone array bones in the third layer, even if the bone sword in his hand was sharp and boundless, and even the magic weapon could be cut directly, the speed at this moment could not be too fast.

But I don't know how long it took, Xie Shi's expression suddenly moved, in front of him, the sword light continued to tear out the bone sword, and suddenly the sword light was stunned, and it trembled strangely, and the white sword body was even more faintly red, making this sword look weird at the moment. At the same time, in this bone sword, Xie Shi suddenly noticed that it actually exuded a kind of guiding power that was the same as when he entered the Yuntian Secret Realm.

And this guidance is impressively towards the deepest part of the hole.

With a frown, Xie Shi put away the bone sword, and instead slapped a black cloth bag on his waist, and suddenly more than ten blood-red hideous flying insects flew out, and after being imprinted with spiritual sense, they flew directly into the hole.

This insect is a red-blooded bee that Xie Shi has been studying for a long time.

These more than ten red-blooded bees fluttered their wings and flew straight to the hole, and after a while, they went deep into it, and Xie Shi's expression became a little weird at the same time, and after a while, he simply summoned the bone sword again and started digging again, and even more spared no spiritual power, urging the huge sword light, so that the speed of its excavation immediately skyrocketed!

Soon after, with Xie Shi's continuous excavation, the hole leading to the depth of the bone pillar has gradually expanded, and it is several zhang in size to the depth, and there is no need for Xie Shi to excavate, and in this hole, there seems to be the power of space permeated, making this hole a cave, and the length has also changed, obviously this bone pillar is only a hundred zhang thick, but in this cave, Xie Shi has already traveled five miles.

And this cave is not dim, there is a faint light emanating, making it hazy and full of mystery. Xie Shi didn't stay too long, but kept moving forward, until the depth of the cave was already more than ten miles, he stopped, and with a flick of his palm, more than ten red-blooded bees flew back from all around and burrowed into the black spirit beast bag around his waist.

At this moment, the cave is already more than ten zhang high, and the surrounding area is very empty, and there is a cold breeze whining and blowing, making the air in it full of coolness.
