Nina came with the first group of scientific and technological aid workers, when the Alliance sent several transport ships back and forth between the Earth and the Moon, because the Earth was in an important stage of rebuilding and the dangerous period had passed, the elites of various fields on the Moon launched a wave of return to Earth.

Mark knows Nina very well, she is not the kind of person who is instigated by others to act on a burst of blood, even if there is no one else with her, she will return to the earth to support the construction, although she usually looks like a lively child, but she is a woman with a very heavy sense of responsibility and the mission of the times, she went down to the grassroots level when the hijacking incident occurred, in order to solve the energy problem she worked as hard as ordinary workers, Mark also knew her at that time, and then she also helped a lot in the process of finding the ruins, After experiencing a series of events in the geological center and the plan to rescue Qin Yi, she also showed her wisdom and courage...... Without her help, Mark might not have been able to get out of Minsk's control.

She was young but not impetuous, with a maturity and stability that did not match her age, and at some times even more reliable than Sun Tan, and Mark could not have thought of a more reliable companion than her.

"I'm going back to the moon in the next few days, although this side has stabilized, but there are still some things that need to be discussed with the alliance again, and then it's time for the reconstruction and resettlement of the moon, people can't live in the spaceship all the time, and maintaining the survival of so many people is also a burden on the lighthouse." Mark took a sip of coffee, and his eyes swept Nina seemingly inadvertently: "You...... Would you like to come and help me? ”

"Are you still short of helpers? Big heroes. Nina tilted her head and laughed.

"To be honest, there is a shortage of people, I don't have a few people to trust, it may be okay now, the situation is more stable, and the people with ghosts will start to move again, and now the strength of the shady faction has risen, they think that instead of consuming resources to impact the speed of light, it is better to collect more materials from the outside world while they have not been closed, and record more information about the universe in the outside world, so that they can develop more calmly after being closed."

"They have a point, don't they?"

"So which side are you on?" Mark asked.

"It doesn't matter which side it is, I just want to do my job." Nina's gaze looked over the guardrail and at the red light coming from below the super drill, and there was a sense of indifference in her eyes: "Is there anything more suitable for me than here?" I can play my best here, I can do the work I love, the geology of the earth is much richer than the moon, if one day the drilling work is over...... I think I'll be a globetrotter and travel the world to discover the great wonders of nature. ”

She didn't answer Mark's invitation directly, but she had already expressed her wishes euphemistically, and Mark didn't say anything more, and talked to her about life problems, Nina's parents are still on the moon, and when everything is stable and the route opens, she plans to bring her family back to Earth.

"Haven't you found your family yet?" Nina asked.

"Well, there has been no news, my phone number and social media have not changed, but they have not contacted me, and there is no news from the local agency." Mark's voice deepened.

"Don't worry, it's going to be fine." Nina reassured him.

"Let's hope so......"

"You look a little haggard."

"I've been tired, especially during this time, I feel that my steps are getting heavier and heavier, and now is the time to be bold, but no matter what I do, I can't be as bold as before, looking back, sometimes I feel that I was too rash at that time, if it wasn't for luck, maybe I would have caused a big disaster." Mark has reflected a lot during this time, and he has indeed done many dangerous acts, including his unyielding death during the alliance peace talks.

In fact, he was not very sure at that time, in addition to self-confidence, he was more of a teenager.

When everything settled down and the earth began to rebuild, Mark became much more stable this year, and when he looked back and thought about the past, he couldn't help but be a little afraid.

Mark's eyes were a little hollow, his thoughts were immersed in the turbulence of the past, and suddenly there was a warm feeling on his body, accompanied by a light and elegant fragrance, which pulled him back to reality from his chaotic thoughts, Nina reached out to stop his neck when Mark fell into frustration, and gave him a real hug, without saying a word, just a shallow smile on the corner of his mouth.

"Thank you......" There was no one else around, Mark still felt a little embarrassed, and quickly sorted out his spirit to return to a normal state, looking a little flustered, and Nina couldn't help but be amused by him.

"You don't have to have such a big psychological burden, and you're not the only one who bears all this, right? You look here, everybody is trying, and there's a lot more people fighting alongside you where you can't see it, aren't they? Nina waved her arms with some excitement and said, "Good news for you, inside news...... Although the drilling has not yet broken through the mantle, we can already harvest a lot of geothermal energy through the volcanic fissures, and soon around this well, the first city in the sixth district will take root here, which is not comparable to the energy of the scale of the Dyson sphere, but there is no problem in ensuring the energy supply of a city. ”

"That's why you're so busy now?" Mark looked at the work platform opposite, and the people coming and going were dense like swarms, busy loading and unloading various goods.

"Not really." Nina stuck out her tongue: "These two days are to celebrate the New Year, no matter how you say it, you can't miss this day." ”

"I've heard about that."

Two days later, the earth will bypass the orbit of the giant planet, officially enter the state of independent operation, that will be the first cycle of the earth's official operation, in this new galaxy, the earth will usher in a new beginning, the old calendar is no longer used, the year in the new galaxy will be changed to the length of the earth's circle around the four stars, people still call this star the sun, the new calendar is much longer than before, the current year is about the past nine years and five months, so calculated, There are only a little more than a decade left in the countdown to the shadows, and people have not yet become accustomed to this kind of life, and they feel a deep sense of urgency.

A new year is the beginning of all things...... Only this time, the festive firecrackers to celebrate the New Year were also the last sound of the starting pistol.
