In this way, Bi Jie took the lead in looking in the col for a long time, but he didn't find any trace of the gray shadow, he was so angry that he scolded: "Damn, what kind of person is this guy, elusive, Bi Yu, your formation ability should be much stronger than mine, you show me quickly, there are any hidden places here, I'll go and find out that guy." ”

"Hehe, you think too much, the formations here seem to be naturally formed, my ability is limited, I can't break it at all, let's let everyone slowly find clues"

Bi Yu smiled bitterly, it was too difficult to crack the formation mechanism here, although he felt that if he really dug into the ground like this, he could find it in the end, but it would take a lot of time to consume, and there was really no need to engage in these things.

Since the Grey Shadow was able to pass through here smoothly, it was tantamount to showing them the way, and the Grey Shadow didn't seem to have any intention of harming them, so they could do their own thing here.

Among the six people present now, except for Bi Yu himself, Ye Fang's cultivation is the highest, and her thoughts are similar to Bi Yu's, so she said to Bi Jie: "We don't have to be in such a hurry, I don't think that person has the intention of harming us, and he is very familiar with the formation here, if you want to get rid of him, I'm afraid he will use the power of the formation to pull all of us into the water first." ”

"Bi Yu, I see that you will tell us all about your experience of encountering that gray shadow just now, I wonder what we can judge from it. ”

Bai Aya'er was still frowning, as if the appearance of that strange person had given her a lot of trouble, even Blue Eyes and Wuxian.

However, Bi Yu thought about it, and still told everyone about the strange person, and after listening to Yu's words, Bai Aya'er muttered: "According to what you say, that person is so familiar with this place, he should have lived here for a while, since he knows the formation layout here very well, why don't he go out?

Bi Yu had been thinking about this question just now, but he didn't come up with the doorway, so he shook his head and said, "I don't know about this, I think I'm afraid he stayed here for other purposes." ”

Bi Jie scolded and said: "That guy shouldn't be able to get out, that's why he studied the formation here, even if he dies himself, are we trapped here?"

While speaking, Bi Yu and the others cautiously passed through several passages, and had come to a huge stone chamber located in the mountain col.

In this stone room, there are a lot of messy things, at first glance, it seems that someone once lived here, and the only thing that aroused Bi Yu's curiosity was that there were a lot of bottles and cans on the ground.

Bi Jie, like Bi Yu, after coming here, began to rummage, and Bi Yu didn't care very much, after all, if there was really a master here, he wouldn't put some hidden organs in his usual place to harm people, if no one came in, wouldn't it be harming himself.

Bi Yu flipped it slightly, and found that these things, after all, after thousands of years, many things even if they had some small formation protection, but their materials were about to decay, and they cracked several lines with a slight touch.

Bi Jie shouted to Bi Yu while rummaging through things, and said, "Bi Yu, this should be someone's daily use, right? Come and see, what are these things?"

This guy is too anxious, even if there is something special, he probably can't find it, and Bi Yu didn't pay attention to him, but slowly squatted down and looked at the bottles and jars on the ground.

These jars are full of dust, Bi Yu is too lazy to pour them out, but is secretly thinking about what is the use, this kind of thing should be very common in the eyes of ordinary people, it is something that individuals will use in their lives, maybe there is nothing peculiar about these things.

Bi Yu really couldn't figure it out, so he was going to take a jar and let Bai Aya'er and them take a look, who knew that Bi Jie actually snatched the jar in his hand, and said a little strangely: "Your jar seems to be a little different, why is it so heavy?"

"Really?"

With Bi Yu's current strength, there is not much difference between dozens of catties and hundreds of catties in his hands, he can only weigh a little different, the power in this body is strong, but it is not as good as before in subtleties.

"If you want to see it, then take it and see it. ”

Bi Yu said casually, and let go of his hand, but what he didn't expect was that he didn't know what Bi Jie thought, this kid's hand didn't hold it steady at all, and then the jar "snapped", fell to the ground, shattered, and the dust inside was also scattered on the ground.

"Hehe, I'm sorry, my hand slipped for a while!"

Bi Jie scratched a little embarrassed, he turned his head to look at the jar on the ground, and was suddenly surprised to find that in this jar, there were many small balls that looked like metal, but they were covered by the dust on them, so they didn't show up.

Hearing the movement on their side, Bai Aya'er hurriedly turned her head and asked them, "What are you doing? What did you break?"

"It's just a jar, it's dirt, it's nothing!"

When Bi Jie saw the things on the ground, he suddenly lost interest, and he didn't even plan to pay attention to those metal balls, but Bi Yu and Bai Aya'er didn't think so.

There is a problem with the col itself, coupled with the strange gray figure, as well as these strange bottles and cans in front of him, Bi Yu quietly looked at the metal ball on the ground, and always felt that it was not a good thing.

At this time, Ye Fang also walked over, and just as she was squatting down, about to pick up a small ball to see what it was, Bi Yu found that these metal balls began to move, and hurriedly said to Ye Fang: "Ye Fang, don't move those things, it's dangerous!"

"Good!"

Although Ye Fang didn't find anything abnormal, she believed Bi Yu's words unconditionally, and after hearing Bi Yu's loud warning, she immediately stood up, took a few steps back, and stood there quietly looking at these metal balls on the ground.

In the amazed eyes of everyone, these metal balls seemed to have life, and they couldn't stop trembling, and cracks appeared, like a chicken breaking through its shell and being reborn.

This did not last long, the crack grew larger and larger, and finally I saw a black body, about the length of a thumb, but something that looked like a mosquito, from the small ball.
