At this time, outside the small valley, an old man appeared, stood on the edge, did not go in, just frowned and looked inside, so many bones, he was very shocked.

He wanted to go in and see what was going on, but looking at so many bones, some of them had not yet decayed, and it was unimaginable that they had gone through a long time.

He could feel that some of the bones that had obviously decayed were filled with a terrifying aura, and he could imagine how powerful the unknown demon clan powerhouse who had fallen here was.

The old man didn't cultivate the formation, but he could also see that here in the small valley, it was shrouded in an unimaginable formation.

What will be in the small valley, the old man does not know, but it must be unimaginable.

He wanted to go in and explore, but he couldn't do it.

He squinted his eyes, and the reason why he had come here to look was because he had just heard a huge movement coming from inside.

After coming, there was no movement at this time, it looked a little strange, he didn't leave, he waited quietly, anyway, there was no way to leave this weird place now.

The old man didn't look anxious at all, and after waiting for a while, another movement came out from inside.

This time, he couldn't help but be shocked, what was going on inside? The formations that enveloped the small valley were all stimulated, and there was some reaction, and the countless formation patterns glowed and brightened, and the terrifying aura was permeated, as if something unimaginable was about to appear.

He looked shocked and had to retreat back so as not to be affected by the inexplicable movement.

This terrible commotion disappeared after a while.

I don't know when, in the other direction outside the small valley, there was suddenly another person, a middle-aged man, who did not approach the old man, but just looked at the movement in the small valley in shock.

The old man naturally knew about the appearance of the middle-aged man for a long time, and his face was a little more vigilant, but he was not afraid, and he retracted his gaze after a glance.

Both of them are dressed in well water, and they don't make it look like river water.

If Wen Bin was here, he would definitely know that these two were seventh-stage masters, the two who were still killed when they fell into it before.

They have no intention of fighting each other for the time being, obviously knowing that being trapped in this strange place, finding a way out is the most important thing.

They both kept a certain distance, and An An was wary of each other.

The middle-aged man didn't stay here for long, and after the movement in the small valley disappeared, he withdrew his gaze, glanced at the old man not far away, and snorted, and left here.

The old man watched the middle-aged man leave, frowned, I don't know what that guy means, this small valley obviously hides a huge secret, isn't it curious? He really didn't believe it.

But he didn't mean to ask anything, a sworn enemy, if it weren't for the inexplicable fall here, they would still be fighting!

He wasn't afraid of that guy, but he couldn't help it, they were all evenly matched, and it was difficult to tell the winner no matter how he fought.

The old man is now curious about who is in the small valley, who is so bold, even if he understands the formation, it is dangerous to enter.

But he also thinks that it is obviously not an ordinary person to be able to toss such a big movement in this dangerous formation.

He was a little hesitant in his heart, thinking about whether to leave here, otherwise it would be difficult to wait for the people inside to come out and see him waiting here and become hostile.

Because he didn't think that the people in the valley would be weaker than him.

The old man pondered for a moment, and although he did not leave, he did not continue to stand in front of the small valley, finding a place to hide and wait.

At this time, Wen Bin, who was recovering in the small valley, naturally didn't know the situation outside, and the fog here was getting thicker and thicker, and people outside couldn't see here.

There is a small valley shrouded in mist, which seems even more mysterious.

It didn't take long for Wen Bin to see that everyone else had recovered, only he was still working hard, and he felt helpless for a while, who called him the only one here who didn't have a spirit stone.

He also wanted spirit stones, but he couldn't find a suitable reason to ask Han Xue for them.

He didn't continue, it was almost over, he stood up and looked at Wu Yu, and said, "Your formation flag, can you replace it with other materials for the time being?"

Wu Yu shrugged helplessly and said, "The problem is, I don't have any other good materials."

Wen Bin pointed to the ground and said: "Look at this soil, it sounds weird, with a forest and yin aura, it may have been eroded by the strange power here for a long time, and it also has some strange power, maybe the nature of the soil is different, it is a good material."

Wu Yu was a little surprised, he really didn't expect this, so he picked up a handful of soil from the ground, looked at it seriously, and gently crushed it with his fingers.

He frowned, these soils really have an eerie aura, their properties have changed, they may not be used to make formation flags, he has never tried to use this material, it is really hard to say, and he has no experience.

Han Xue was also curious to pick up some dirt and take a look.

Bai Liu said with a solemn expression: "What is there under this formation?" There is such a terrible yin qi.

This is still under the suppression of the formation, and a little leakage may be insignificant, but even so, it is enough to erode these soil erosions and become negative, it is really terrible to think about. “

Wen Bin also felt that the things below must be unimaginable, just think about it, anyway, they don't have the strength to explore.

He looked at Wu Yu and said, "What, can it be used as a material for refining the array flag?"

Wu Yu said: "Although I haven't tried it with this material, I can try it."

Han Xue was surprised: "Wu Yu, are you going to refine the array flag here?"

Bai Liu and Bai Qing both looked incredulous.

Wu Yu coughed dryly and said: "You can also refine here, this clay is a good material, that is, my refining methods are average, but it is enough to refine the array flag to be strong."

He knew that there was no way to refine a good array flag here, so he could only use it.

Next, Wu Yu began to refine the array flag, and there was no intention to hide it, just let them look at it.

Wen Bin had already seen it once, and he wasn't very interested, he just wanted to know if these negative soils could be refined.

If he could, he would have liked to use it to refine the puppet, especially the scarred zombie.

He's worried that he doesn't have the materials to refine it!

Han Xue looked at Wu Yu refining the array flag seriously, in her opinion, this is also a kind of refining weapon, if she can learn something, won't she make a lot of money? This will be of great help to her in learning to refine puppets in the future.

Bai Qing and Bai Liu, although they don't know how to refine weapons, they also watch with relish.

Wu Yu used it for a while to refine dozens of array flags, but because the material was too single and the durability was not strong enough, it might be scrapped after a few uses, but in this case, it was already good to be able to do it to this extent.
