The construction speed of the sixth area is far faster than people expected, in fact, the people in charge of the project did not expect that the progress would be so smooth, perhaps after a series of bad luck, the time has finally come for mankind to come to the end of the pole, the follow-up activities caused by the volcanic eruption in the Antarctic region have not happened, and the active crater seems to be asleep, obviously still contains terrible destructive power, but has not been vented at all.

The first to be erected are the four drilling pillar towers around the Siddeli crater, these four metal towers are 400 meters high, which is nothing compared to the big underground holes, but they are all giants when taken out alone, and the surface of the towers is made of heat-resistant nanometal, which can withstand the extreme heat of the underground after being coated with a special coating. Once they've been built, the next step is to build scaffolds on top of the towers and build super wells.

This is an epic project, the previous super drilling in front of it are all pediatric things, special tungsten alloy drill bits each weigh thousands of tons, are connected to the top of the drill rod, can drive it rotating drilling rigs are the engines used by space warships, the principle of drilling is actually very simple, every time the drill bit drills to the bottom of the hole, the powerful engine will drill through the bottom of the hole, so that the hole will continue to deepen.

The problem is that in this process, a large amount of underground waste will cause accumulation, the drill bit will also be damaged by high temperature, how to solve these problems is the difficulty, although there are more solid materials, but to make such a large volume, but also economical and practical, or can only use the tungsten gold drill bit invented during the Cold War, the current cooling method can maintain the drill bit in the environment below 500 degrees Celsius to work, even so, each drilling still has to scrap several drill bits.

Each drill bit can only advance the progress a little bit, and it is still far from the center of the earth where the eggs are hidden, and the process of advancing is getting more and more difficult, high temperatures, cavities, and lava are all difficult to break through, but compared to flying at the speed of light, at least humans still have a clue to overcome these difficulties, so far the personnel involved in the project are still full of struggle, fighting with the stratum day and night.

Mark also came here after being busy with various administrative affairs in East Asia, not that he had any work in the sixth district, but just to take a look, when he was on Earth before, he didn't even have the opportunity to go abroad, either busy studying or taking care of work, the irony is that Mark went to the moon for the first time he went far away...... Now he has a chance, and the whole world is letting him play around, but he doesn't have the heart to do that anymore.

Soon Mark is going to return to the moon, according to the agreement of the alliance, after the completion of the placement of the earth, the moon will also leave the core area of the alliance, and Mark will have to discuss the detailed questions with the representatives of the alliance again, and finally stay on the earth for a few days, Mark plans to come and see this geocentric drilling.

It is completely different from the Antarctic he imagined, after the volcanic eruption, the Antarctic ice sheet has melted a large area, and now only the central part of the continent is still preserved, and the rest of the country has exposed a large area of yellow-brown surface, and even the warmer climate has grown into a native tundra, if he didn't see it with his own eyes, Mark would definitely not believe that this is the current Antarctic continent.

The super geocentric drilling is really working, and the loud noise emitted can be heard from dozens of kilometers away, and the tranquility of this ancient continent is broken, and four huge support pillars stand around the crater, and the special coating emits a silver glow in the sun, which looks extremely dazzling. Mark originally just went to look casually, but he never expected to meet acquaintances in this place.

Hearing that Mark came to visit and inspect, the person in charge of the geocentric drilling came out to greet him personally, Mark did not want to affect their normal work, but the other party still took him to visit the internal facilities very enthusiastically, and Mark saw a familiar face on the drilling bench, it was none other than Nina, who had fought side by side with him and experienced a series of events.

She doesn't look the same, she is still so beautiful and energetic, full of enthusiasm for her work, at this time she is debugging a large machine against the data, her slightly curly long hair is coiled up by her, tied into a neat ponytail, and the whole person looks very energetic with the work uniform that closes her body.

After the ship was born, they separated, and after that, there were too many things, and Mark never went to look for her, but he didn't expect to meet her here.

The other party looked up slightly and saw Mark, not as shocked as he was, but there was still a bit of surprise in her crescent smile, and after finishing her work, she ran out of the platform, jumped up and ran to Mark like a cheerful squirrel, and playfully patted him.

"How did you get here?" Nina asked with a smile.

"Shouldn't I ask you?" Mark crossed his hands to his chest.

"I'm a geologist, what better place for me?" Nina grinned.

"Where did you go when you got on the ship? I haven't been able to find you since. ”

"Where can I go, when the earth began to jump for the second time, the lunar spacecraft chased and left the solar system, the lunar surface soon became uninhabitable, I followed my family to the underground and lived in the spaceship, and then the communication has been bad, I can only stay at home all the time, there is nothing to do, I can only meditate and retreat, hone my mind and intuition......"

"A year ago, I came to Earth with a scientific research team, this is my first time on Earth, and I can be regarded as witnessing its revival, there is one thing to say, this place is really beautiful, much more beautiful than the moon, I saw the sea and blue sky for the first time, stepping on the land where my ancestors walked, I seemed to feel some wonderful induction......" Nina is still so cheerful, as soon as the conversation box opens, she gushes endlessly.

"You're still so chattering." Mark laughed.

"It's not a god's chatter! I'm serious! I said that things will end well in the end, do you believe it? Nina said with a wink.

"It's not a good ending, is it...... In other words, we have to fight for the ending ourselves, and now everything is just beginning. Mark smiled wryly.

"Then when the end comes, it will definitely be a good ending, I calculated it accurately, and I have never made a mistake."

The two of them walked to an employee rest area, Nina poured Mark a cup of coffee, and the two of them sat next to the noisy drilling machine, talking about what happened during this time, and they had a good conversation.
