"Is this cave really that safe?" Zhang Daniu was still a little unconvinced, he touched it around, except that the tentacles were cold and the texture was like jade, he didn't feel anything special. Pen? Interesting? Pavilion wWw. ｂiquge。 info But since she dares to say that, she must not be deceiving herself indiscriminately. He sacrificed the Purple Sky Thunder Sword and blasted towards the walls of the crypt. The Zixiao Thunder Sword slammed into it, and it slid away without any suspense, and it couldn't even be stalemate with it.

Whenever it enters the phase of stalemate, it is because the sword body has been pierced inside, forming an inconspicuous notch, stuck on the sword body and rubbing against each other. Whoever has a tough texture will be able to win. It's a pity that the wall itself is not damaged at all, and the tip of the sword has nowhere to be forced, so it can only slide away helplessly again and again. He was amazed: "Is it something remarkable in itself?" ”

"I studied it for a long time, but I couldn't find its origin, let alone refine it. And in addition to its particularly hard texture, it is not much different from ordinary boulders. "This crypt is so extraordinary, she must have put in the effort to fiddle with it. But without exception, they all failed. If it weren't for the shimmer of hope, she wouldn't have said that. "I think instead of focusing on this unknown thing, it is better to plan well and restart the blood sacrifice!"

"Blood sacrifice?" He is not unfamiliar with this term, after all, even in modern societies with highly developed civilization and greatly strengthened human rights, there are blood sacrifices. The so-called blood sacrifice is the sacrifice of blood or bloody flesh to a certain void being. Most of this blood is freshly taken, which means that it must be slaughtered on the spot after the ceremony begins. The reason why the blood sacrifice is notorious is not because of the bloody scene, but because some people sacrifice people alive, which makes it unacceptable to others.

However, the core of his entanglement is not here, he is just guessing the purpose of the blood sacrifice. The blood sacrifice of the ignorant is to pray for the protection of the gods, but in this world, no one would do such a stupid thing. At least, as the Ten Thousand Soul Blood Demon who was once the closest to the supreme "god", he would never rely on bloody killings alone to pray to the Holy Immortals to protect him. And this is the world of Xianxia, and the blood sacrifice should not be as simple as a simple sacrifice.

Sure enough, the statement he heard from her mouth was completely different from his common sense, or subversive. "That's right, it's a blood sacrifice. When I wanted to break through the void and ascend to the heavenly realm, I needed a great amount of spiritual energy to push me. Activating that formation required a tremendous amount of energy, and the throughput of the earth's spiritual veins alone was far from satisfying the demand. Therefore, I sacrificed all those earth spirit veins with blood, and used the surging power after the blood sacrifice to break through the void in one fell swoop. Now that the two sides are fighting endlessly, there is no time to take care of us, and the endless flesh and blood fall on the remains of the once great array, as long as we secretly activate the blood sacrifice ritual and wait until we have gathered enough power, we will not be able to control them...... When the time comes, they just want to stop, and we can all borrow the power of the formation to kill them easily, and then complete the blood sacrifice! ”

"Tremendous power?" Zhang Daniu didn't pay attention to the others, and didn't even listen carefully to her analysis. He thought of something else at once, so much so that he put down the crisis in front of him. But seriously, although he was in danger, he was not in danger. First, those demon beasts didn't regard him as a target, and second, he hid in the "bomb shelter", and even the aftermath of the battle couldn't hurt him, so it couldn't be called a crisis. Once he was safe, he began to think about some off-topic questions, such as: "Is it possible to use the power obtained from the blood sacrifice to refine the sea of blood?" ”

She didn't expect him to ask like that, as a normal person, what he was thinking about at this time should be how to leave. However, as a servant, she could only answer the question honestly: "You can refine the sea of blood, but the rest is not enough to break through the space......"

"You forgot, we caught the old man of Tianshan, he must know another way to get out of here." He smirked. Glancing at the magic flag in her hand, there was still an unlucky immortal trapped inside. As for whether to refine him, Zhang Daniu hadn't thought about it yet. After all, they are all righteous people, and the other party doesn't have much malicious intent on their own, so it seems a little inappropriate to fall into the well like this. Moreover, now that his magic flag is going to be refined, it is still unknown whether he needs a Yin Spirit, so he didn't do it easily. However, whether it is refined or not does not affect his forced exit, after all, the old man of Tianshan does not want to stay in this kind of place where birds don't all the time.

"Yes!" Since he had an idea, she didn't say anything more. She returned the magic flag, and then sneaked out, busy unnoticed. Wanting a blood sacrifice is not an easy matter, and you must prepare in advance. Fortunately, this place is the former site of her blood sacrifice of thousands of spiritual veins, although tens of thousands of years have passed, and basically the buildings on the ground have been weathered, but there are still many things buried in the ground that can still be borrowed.

Because of the fierce battle above, both the Plague King and Nangong Yu had no time to take care of the situation outside. Endless demon beasts gathered together, so that they couldn't kill them all, where would they still be in the mood to care about the ten thousand spirit blood demons that sneaked out. As for those demon beasts, most of their energy is focused on the encirclement, and even if there are some who can't squeeze in occasionally, they can't find her who is deliberately hidden. Besides, even if they found out, would they still be able to beat her who had already recovered to the strength of an immortal?

It's not the first time she's done this kind of thing, so she's pretty familiar with it. Instead of trying to arrange the most perfect Blood Sacrifice Formation, she roughly laid out a prototype and then began to guide the formation to work. This Blood Sacrifice Array was her original creation, and it didn't have any power at first, but as more creatures were killed and its quality increased, it gradually gained power from it. And as the power became stronger and stronger, the operation of the formation began to become unstoppable.

It's like a juicer that's just starting to run, but once it's turned completely, it can crush anything in it in an instant. Now she's just building a shelf and then using her own power to push it around. Then, while waiting for an opportunity to absorb the power gained by the Blood Sacrifice Ritual, he repaired this rough formation. Compared to the last blood sacrifice, the effect this time is obviously more obvious. After all, what she killed before was a bloodless earth spirit vein, which was just a symbolic killing, which was different from the real blood sacrifice. This time it was different, every moment there were creatures being killed, and fresh flesh and blood were falling down with a puff, which was much more obvious than the effect of her own killing.
