Shangguan contacted the female officer from the satellite reconnaissance office and asked, "Haven't you found any suspicious situation in Antarctica?" ”

"Yes, chief," replied the female officer, "except where you have been through. ”

"Continue to watch closely."

"Yes, Chief."

Shangguan leaned against the railing of the warship, looking at the individual soldier computer on his arm, researching the Antarctic map. As can be seen from the map, there are no other structures or humans within a radius of at least 300 kilometers marked as an alien base, except for the research station and refugee camp.

So Shangguan had a bold idea in his heart at the moment, the dark night built the challenge place here, just to avoid human disturbances, and after it was built, he reminded Shangguan Yu to take his team members to the challenge.

Princess Anna has a pact with him, that is, she can't continue to kill humans, so Dark Night wants to say that the challenge field is built in a place where no one is around. But at the same time, the secret of his construction base was discovered by humans, so he unleashed aliens to kill these humans, and by the way, several soy sauce fighters at that research station were killed.

And it is still unknown whether these four people who were rescued by them can survive.

If all of the above can be said, Shangguan Yu speculated that in Antarctica, except for the underground base in the dark night, there are no aliens or other monsters in other places.

There are still three days left until the day of the challenge, so there is still plenty of time. But the enemy's base has already been found out, so it can be visited at any time.

This can be regarded as Shangguan Yuneng's most active challenge in turn.

Shangguan Yu was studying the South Pole here, and several girls over there were talking about the trip to the South Pole with Alice, which was thrilling, and Alice's blood was surging when she heard it, and she actually strongly asked to join Shangguan Yu's team.

Shangguan Yu looked at the time and said, "Girls, it's time for us to go on the road." ”

"A little more rest." Ran Ran said.

Shangguan Yu had already jumped on the frisbee and said, "Those who want to rest can stay, and those who don't want to rest should come up quickly." ”

Senna and Li Zhenai hurriedly got on the frisbee, and Ran Ran followed closely, and Alice shouted, "Brother Yu, Brother Yu, take me." ”

Shangguan Yu shook his head at her, and Alice watched them leave in extreme disappointment.

"Ranran, you come to drive," Shangguan Yu handed the driver's seat to Zhao Yiyi, and then leaned against the railing, took out the right stick, and began to make buff bottles again.

Senna asked, "Do you want to do it again?" ”

Shangguan Yu nodded and said, "Yes, I want to do more invincible buffs, these ghost things are too terrifying, too disgusting, too powerful." Let's be careful. ”

Shangguan Yu made some invincible buff bottles and gave them to the girls, so that everyone has 15 of them, and they can remain invincible for more than seven hours.

After the production was completed, Shangguan Yu wanted to return the pilot, and the pilot's frisbee flew quickly on the Antarctic continent. There were no twists and turns along the way, and soon I came to the place where the alien base was located.

It's a large valley with no alien flying saucers, equipment, and supplies. The valley was flat, covered with a thick layer of snow, and there were no traces including footprints.

In the middle of the valley, there is a five-meter-diameter hole in the cliff wall, and the inside is black.

The frisbee hovered above the valley, and Shangguan Yu asked: "The invincible buff is all on, look at the time of use, if the time is almost up, hurry up and replenish it, we are going down." ”

Shangguan Yu lowered the frisbee as he spoke, turned on the searchlight, and drove into the hole, which was actually a tunnel with a 45° oblique angle, inclined down.

The walls of the cave are very smooth and smooth, and at first glance they have been excavated by hand.

Shangguan turned around and asked, "Are you afraid?" ”

The three girls all shook their heads to indicate that they were not afraid, but Shangguan Yu could still see the fear. He said, "Protect yourself." We're going to get ready, Sister Sena, and throw a signal relay at the entrance of the cave. ”

Senna nodded, and dropped a remedial on the ground outside the hole.

Since you want to go deep into the alien cave, it is very likely that there will be a signal interruption with the outside world. Shangguan Yu thought of this when he came, so he deliberately brought a lot of these small things that could be relayed and amplified radio signals.

Senna summoned the drone back, took control of it, and flew down the hole.

The frisbee just hovered at the entrance of the cave, waiting for the drone that went down first to send a message.

The drone flew for a long time before it reached the bottom of the cave, and everyone couldn't help but be surprised when they looked at the picture that came back.

What is shown on the screen is a huge underground space, and in this huge space, there is actually a huge pyramid!

This pyramid is the huge underground pyramid detected by satellites, which is 920 meters long on one side at the base and 586 meters high.

On and around the pyramid, there are stalactite-like pillars supporting the top of the cave.

It can accommodate such a huge pyramid, but imagine how huge this underground cave is.

The largest pyramid in the world is the Pyramid of Khufu in Egypt, which is only 230 meters long at the base and 146 meters high. The underground pyramid in front of you is four times the length and height of the Pyramid of Khufu, and its volume is 64 times that of it.

In other words, this underground pyramid can hold 64 of the world's largest pyramids of Khufu.

Shangguan Yu connected with Zhao Jun and asked, "Chief, didn't there be any reconnaissance intelligence records about underground pyramids in Antarctica?" ”

Zhao Jun replied decisively: "No, when I discovered this underground pyramid, I checked the relevant information, before the end of the world, many countries have carried out satellite exploration of Nanjin, and no underground base has been found." ”

"So, the pyramid was built overnight in the dark?" Shangguan Yu asked, this is also incredible!

Dark Night is a turbidity, and with this technology alone, the turbidity can also throw dozens of streets of earthlings technology!

Shangguan asked Sena again, "How deep is this tunnel?" ”

Senna replied: "The tunnel is 10 kilometers long and goes down at a 45° angle, so the depth of this hole is 7 kilometers underground. ”

This behind-the-scenes player Dark Night is literally a bunker, able to dig a tunnel with a diameter of five meters, a length of 10 kilometers, and a depth of 7 kilometers in just three days, and build a huge underground cavern at the end of the tunnel.

And in this underground cavern, a huge pyramid was built that could hold 64 pyramids of Khufu!

That's how powerful it is.

And the purpose is to let Shangguan Yu challenge.

Damn, you can look up to me, in that case, I can't live up to your kindness, so okay, the master is here!
