Let the praying mantis leave the mysterious closed place, except for the praying mantis, a few people, each go to a passage in the mysterious place to guard.

If a humanoid comes out, notify him as soon as possible.

The praying mantis soon returned, standing on the table in the form of a small praying mantis.

Gu Bo talked to the mantis divine sense, and learned that the humanoid creatures in that place didn't seem to know how to leave, and even didn't know that there was a place other than that mysterious place.

That mysterious place is actually a huge underground space, but it is separated by a barrier, which is not natural, but artificially created.

It is unknown who created such a barrier and enveloped the underground space.

Gu Bo is amazed, I have seen it before, and some people speculate that under the earth, there is a huge space, or rather, where hell is.

Unexpectedly, there really is a huge underground space.

When the Soviet Union suddenly stopped drilling, there were rumors that he had gone to hell and heard the devil's roar, and Gu Bo even wondered if he had gone into this mysterious space.

But it's impossible to think about it, that barrier, even a nuclear bomb can't be blasted open, how can it be drilled open?

But maybe it's a weak point, or maybe the walls are not the same defensive and can withstand a furious bombardment, but the defense is weaker for a sustained drill attack?

The screams of the devil that I heard at the beginning may have been mistaken for hell because of the death of a creature in a mysterious place.

Of course, the above is just speculation, but on Earth, there is a huge underground space, but it really exists.

It is not easy to enter the underground mysterious space, even in the passage, it is very narrow, and it is impossible to enter directly.

You have to pass through the terrestrial barrier to be able to enter it.

Fa Yi and a few people were brought in by the praying mantis directly across the space, otherwise it would not be easy for Fa Yi and a few people to enter, or even be unable to enter.

Gu Bo decided to go in person and take a lesson, after all, he was a cultivator, and he had no strength, but he had nowhere to play, and he was a little depressed in his heart.

It just so happens that there can be a place where you can test it, and maybe you can kill aliens.

Or, can you open up the passage and use this mysterious underground space as a base for the cultivation world?

Gu Bo thinks it's feasible, and there are many elixirs and spirit beasts in it, even if the level is low, but it's also a high-grade thing.

Having made up his mind, Gu Bo opened his eyes, patted Qi Min's little hand, and said, "Violent girl, you can go back later, I will leave for a while, and the specific number of days will be uncertain." ”

"Will it be dangerous?" Qi Min suddenly became nervous.

Gu Bo smiled, "I think too much, where is there any danger in this world." ”

"Isn't there really any danger?" Qi Min still looked worried.

"Don't worry, in this world, there is no threat to my existence, lie to you is a puppy!" Gu Bo stood up and put his arm around her shoulder.

Qi Min didn't leave the manor, and Gu Bo naturally didn't mean to drive her away, Gu Bo didn't say goodbye to Qi Min that night, and directly took the sword into the air and left the manor with the Wind and Fire Mantis.

This time, Gu Bo was about to enter that mysterious space from the passage of Shennongjia, this was not the first time Gu Bo had flown with a sword, but it was the first time he had used a real flying sword.

In the night sky, a cold light flew by, faster than a meteor, maybe someone on the ground saw this light, but they would only think it was a meteor.

The speed of Gubo Edgeworth's flight is very fast, even if it is a hypersonic vehicle on the earth, it cannot be compared, and it will not take long to come to Shennongjia, a place with many mysteries in China.

In the depths of Shennongjia, there are strange animals, such as strange insects that will turn into a few insects if they fall into several sections, or albino animals, and the more legendary ones are naturally the legends of the savages of Shennongjia.

Gu Bo came directly to the depths of Shennongjia, and his divine sense spied on all movements within a radius of five kilometers, even if it was a single insect, it could not escape his divine sense.

After stepping into the middle stage of the Erhua Yun Divine Realm, Gu Bo's divine consciousness coverage skyrocketed from nearly two kilometers to a little more than five kilometers.

When approaching the depths of Shennongjia, Gu Bo noticed a strange change, as if there was a magical power lurking here, changing everything around him.

Even the magnetic field, under the interference, has undergone some mutations.

I can't help but think of Kunlun's Death Valley, maybe it's because of this inexplicable power that it will become so magical.

Along the way, Gu Bo saw two white bears, as well as some other albino animals, and even some more peculiar animals, but he did not find the existence of wild people.

The passage into the mysterious space is in a valley deep in Shennongjia, where there is a cave, and the one guarding this place is Fa Er, who saw Gu Bo coming, and hurriedly saluted respectfully.

After entering the cave, go all the way, but only a few dozen meters, and you will reach the end, except for some small holes, there is no passage.

If you don't know it, I'm afraid you think that this cave is already in the end.

In fact, it is indeed in the end, although the passage is here, it is not directly connected to the cave.

"Let's go. Gu Bo greeted and continued with the praying mantis.

The second law, on the other hand, stayed in the cave and continued to guard the passage.

Gu Bo's body glowed with an earthy yellow light, and his body flickered, and he had already escaped into the soil, which was the art of earth escape that he had just practiced for a short time from the exercises of the Shangxuan Sect.

All the way down, about five or six hundred meters into it, Gu Bo noticed a barrier, this barrier is a bit special, and he doesn't know what material it is built of.

There is an inexplicable power emanating from it, and the magic of Shennongjia may be related to this.

This is where the portal of the passage is, Gu Bo directly cast the earth escape technique, and escaped inside, unexpectedly, there was no obstruction, although the speed of escape slowed down, but there was no obstruction.

Obviously, this barrier will not stop those who enter with the art of earth escape.

Gu Bo was very curious, who was the person who built such a mysterious space, could it really be an alien?

Or is it a rumored remnant of an ancient civilization?

Some people have proposed, or found from some ruins, that there is not only this current human civilization on the earth, but also a glorious human civilization in ancient times, but for some reason it went to extinction.

Seeing this mysterious place, Gu Bo couldn't help but believe a little, or is it really a remnant of an ancient civilization?

This barrier is tens of meters thick, and after passing through the barrier, it appears in a passage, which is somewhat dim, but not completely dark.

At the front of the passage, there was a faint light coming through.
