And as the iron cover was opened, a huge iron pipe-like thing appeared in the center of the pit, and gusts of cool wind were blown up through the iron pipe, making people feel a bit chilly for an instant.

Chi Meng looked inside the railway, and the inside of the iron pipe was completely pitch black, and he couldn't see to the end.

With a movement of her hand, she used a burst of energy to roll up a stone on the ground, and then threw it down at the entrance of the cave.

The depth of water can be probed with stones, and the depth of caves can also be probed naturally. The principle is to use the sound produced by the falling stones to distinguish the depth.

I don't know how long it took, Chi Meng even got a little impatient waiting, but there was still no sound coming from the iron pipe.

This makes people feel very strange. Could it be that there is still a beast living here, and it can eat the stone with its mouth wide open?

Otherwise, how could there be no sound?

Even if there is some kind of curve in the deepest part of the iron pipeline, there should be a very subtle collision sound.

Yes, this kind of sound may be extremely small, and it may be completely inaudible to the human ear, but what Chi Meng uses is not the physical ear, but the spiritual sense.

Under her spiritual consciousness, she can hear all the sounds below clearly.

This makes people feel extremely strange. What's going on here?

Chi Meng frowned deeply involuntarily, and was a little dumbfounded for a while... The men in black were not idle, they immediately manipulated the power in their bodies, focused on their weapons, and began to dig down.

These people's cultivation base is not bad, and they cooperate very well. Under the shocked eyes of Shangguan father and daughter, they dug out a hole about one meter in length and width and about two meters deep into the ground in just ten minutes. potholes.

A man in black immediately jumped up, cupped his hands and said, "Special envoy, I found something."

Chi Meng looked down, and sure enough, in the mud of the pothole, he found an iron cover covered by the mud.

Because of the baptism of time and soil covering, the iron cover is already rusted and mottled.

"Be extremely careful when handling it, don't break it." Chi Meng instructed.

Several men in black took the order and immediately surrounded the iron cover. Afterwards, each of them radiated energy to wrap the iron cover tightly, and then began to lift it up slowly, trying to open the cover.

However, the lid seemed to be very tight. Even though several people cooperated quite well, they still didn't budge.

"Come again." Chi Meng waved his hand.

Sure enough, dozens of men in black ran out of the surrounding grass in an instant, rushed to the vicinity of the pothole at an extremely fast speed, and joined the team that pulled out the iron cover.

Shangguan Qinghai and Shangguan Qingyan were stunned.

They also followed this group of people for some distance, but along the way, they really didn't realize that there were so many people in black around them.

"This group of people doesn't look simple." Shangguan Qinghai couldn't help but whispered to Shangguan Qingyan.

"Everyone is a master. It's not without reason that our guards were dealt with directly by them." Shangguan Qingyan couldn't help sighing.

"The origin of this group of people is unknown, and it is very scary. However, if they really help Han Sanqian, then Han Sanqian will indeed be able to get a helping hand."

Shangguan Qingyan nodded: "Looking at their appearance, their identities are very mysterious, and I don't want anyone to know their identities. It's better for us father and daughter not to guess them, just do what they say."

Shangguan Qinghai nodded and said no more.

The best way to deal with these people is to keep silent. If you talk too much or think too much, it is very likely that you will bring yourself a fatal disaster.
