The autopilot flew at a speed of more than Mach 10 and kept flying north.

"Brother Meng, where are we going?" Yang Guang couldn't help but ask.

Meng Pojia lay on the seat, crossed Erlang's legs, and said with a smile: "I don't dare to answer you this question, I'm afraid that your question will not be finished, I am most afraid of answering the question, you better wait and see for yourself." ”

Yang Guang smiled helplessly, no matter what he thought, the answer was about to be revealed anyway, and it wouldn't be bad for a while.

So I simply closed my eyes and rested, since I was here to do something, let's first recuperate enough to talk.

In the chaos, I don't know how long it took, Yang Guang felt that the aircraft began to slow down significantly.

When I opened my eyes and looked out the window, I saw the brilliant aurora borealis, and below it was a snow-capped world, with huge icebergs everywhere.

It seems that now they have entered the confines of the Arctic Circle.

Yang Guang couldn't help but wonder, how did he run to the North Pole, could it be that the ruins of ancient civilization are here?

The aircraft continued to fly forward, eventually coming to a halt.

At this time, Meng Piercing opened the inner skylight of the aircraft, revealing a transparent cabin.

He pointed to the top of his head: "Xiao Yang, you must have never seen this." ”

Yang Guang looked up and couldn't help but be surprised.

I saw a huge circular hole in the thick clouds of the sky, through which you could see the cosmic starry sky with a pitch-black background.

The thick clouds overhead swirled rapidly around this circular hollow, and Yang Guang felt as if he was standing in the eye of a super-large tornado, which was very strange and terrifying.

He even had the illusion that this huge hole would suck the tiny craft into it and then shoot it into outer space.

Yang Guang subconsciously looked at the positioning system of the chip: 90° north latitude / 0° west longitude.

The current position is already the exact north pole of the earth.

And in the Arctic Pole, there is such a strange meteorological phenomenon, how is this caused?

Yang Guang looked at Meng Pojia a little suspiciously, and the latter smiled bitterly: "Don't ask me, I can't explain this kind of thing clearly."

When you see Professor Zhang, you can ask him for advice......

Alright, let's go down. ”

As Meng Pojia's voice fell, the aircraft began to glide down, and below it were four huge icebergs leaning together.

There was a huge gap between the four icebergs, and the aircraft flew into it very flexibly, which made Yang Guang feel even more shocked.

Four icebergs surround it to form a deep valley covered with snow, and in this deep valley, a circular entrance is slowly opening.

I don't know how big this entrance is, because they were already inside when it was opened to allow the aircraft to pass through.

Yang Guang only glanced at the wide, circular passage, and the entrance closed, and they were plunged into darkness.

The autopilot flew effortlessly through the invisible passage until a faint light appeared in front of him.

The light became brighter and brighter, and it turned out to be a circular hole, and after flying out of the hole, an underground world appeared in front of Yang Guang's eyes.

Strictly speaking, this is a very large underground base, with a height of thousands of kilometers and a radius of at least five kilometers.

Strangely, the space was filled with a moderate amount of light, but there was no obvious light source in sight.

There are not only many large and small buildings, but also many kinds of aircraft and various mechanical equipment.

Many people were busy in the base, and Yang Guang soon saw his two masters and a few others, looking eagerly at their flying machines.

In addition to Shi Chong, Ding Man and Zhang Yuanshan, Yang Guang also saw Zhang Jin.

"Welcome to the Arctic Archaeological Base. When he got off the plane, Meng Pojia patted Yang Guang on the shoulder.

After meeting with the master, Yang Guang immediately learned about the so-called archaeological base.

It turns out that the construction of this base began more than 100 years ago and has a history of nearly 100 years.

Since the discovery of the passage to the underground at the north and south poles more than 100 years ago, mankind has quickly discovered the remains of civilization hidden deep underground, and only then began to build a base in this huge space.

In the Antarctic and the Arctic, there is one such archaeological site.

These two archaeological bases are outposts to explore the underworld, and the deeper underneath the base is where the real secrets of the underworld lie.

All major countries in the world have workstations in two major bases.

As the largest country in the world, Huaxia has the largest number of archaeological workstations, reaching twelve.

Each of the twelve workstations is set up by a different archaeological institution.

All workstations are both cooperative and competitors. What they are competing for is naturally the relics of civilization in the underground world.

After the relics of civilization are excavated, except for some scientific and technological knowledge that is of great use to the entire human race, everything else belongs to the institution that first excavated it.

It is really because of this incentive mechanism that all countries in the world, or major consortia, have vigorously established archaeological institutions, and the remains of civilization in the underground world have been continuously excavated in the past hundred years.

"We're having a bit of a hard time this time, so we'd like to ask you to help. Zhang Yuanshan's words seemed a little polite, but it could also be seen that he also seemed to have great expectations.

"Uncle Zhang, you're polite, what's the situation?" Yang Guang asked directly.

Zhang Yuanshan wanted to speak and stopped, and immediately said: "That's it, let's talk about it when we get to the place." ”

A group of people walked into the largest building in the base, and there were several eye-catching Chinese characters on the building: "Arctic Archaeological Base", and Zhang Yuanshan told him that the original base was pioneered and built here by the Chinese people.

Entering the large hall, after completing the formalities, they entered a room with a police guard at the door.

When I went in, I realized that this was a large elevator room, but these elevators looked like big cylinders, and everyone entered them.

The elevator descends quickly, so the elevator is also equipped with seats with seat belts for easy use by ordinary people.

The elevator keeps descending, and although the speed is amazing, there is no sign of reaching the end of the line.

Yang Guang couldn't help but speak, it's been more than ten minutes, how deep does this have to go.

In the end, it finally stopped, it took about forty minutes, and I don't know what depth it reached, Yang Guang only knew that before the elevator stopped, before their group of passengers knew it, the elevator had rotated 180 degrees in the vertical direction

They are now theoretically in the elevator in a handstand, but Yang Guang is strange that he does not have any feeling of being upside down.

At this point, the elevator doors opened, revealing the elevator hall at the other end - it was an upside-down elevator hall.
