On the way home, Pang Xuelin stopped by to pick up little Murphy.

The little girl hadn't seen Pang Xuelin for more than two months, and she didn't want to come out when she was tired of being in Pang Xuelin's arms.

Pang Xuelin simply let Big Murphy be the driver, and he sat in the back of the car with his daughter in his arms.

"Hello, do you want your father?"

"Yes!"

Little Murphy was only seven years old, dressed like a doll, Pang Xuelin couldn't help but kiss her, and she was pierced by the stubble on Pang Xuelin's face and giggled.

The father and daughter played all the way until they reached the house, and then they stopped.

Pang Xuelin's return made this slightly deserted home quickly become lively.

Especially in the evening, when she learned that Pang Xuelin had a one-month vacation, Chrissy turned over to be the master, turning her thoughts for several months into endless lingering, so that Pang Xuelin enjoyed all the tenderness.

It's just that this girl is destined to be a scumbag of war, and she only came for two rounds, so she lay on Pang Xuelin and didn't want to move.

"Husband, how have you become so bad lately?"

"Don't like it?"

Pang Xuelin laughed.

Chrissy glanced at Pang Xuelin, bit his ear and said, "I like ......"

Pang Xuelin was thrilled by Chrissy's coquettishness, and pressed Chrissy under him again.

It wasn't until Chrissy was completely out of strength that the two hugged and chatted, and before they knew it, they fell asleep deeply.

For the next month, Pang Xuelin helped Chrissy with farm work and housework at home every day.

The family has planted more than 200 acres of cornland, and although they are now past the peak of their busy farming season, they still have countless jobs to do every day.

Pang Xuelin felt sorry for Chriss, so he simply learned from Cooper and helped Chrissy transform the harvesters, seeders, and pesticide spraying drones at home into machines with a certain degree of artificial intelligence.

In addition, in this era, whether it is fuel or other energy sources, it is extremely cheap, so this makes Chrissy's daily work a lot easier.

When the two are free, they either go out by car, or take little Murphy out for a picnic, and the family of three is happy.

A month of happiness flies by.

A month later, Pang Xuelin appeared in the NASA conference room to participate in a discussion on the latest version of the Lazarus Project.

In the movie, human spaceflight is still maintained at the level of chemical propulsion, coupled with the gravitational constraints on Earth, even though the Eternal Night spacecraft has spent a lot of human resources, the entire spacecraft is quite primitive.

Compared with the vastness of the universe, it is as if human beings in ancient times relied on simple canoes to cross the vast ocean in search of a new continent.

This risk meant that every astronaut who participated in the Lazarus program would die.

This time, anti-gravity technology has developed by leaps and bounds in theory, coupled with some of the technologies left over from the shrimp man civilization back then, human beings can basically guarantee that the application of anti-gravity technology from theory to engineering can be completed within three years.

Therefore, after repeated discussions between Pang Xuelin and Brand, the latest "Eternal Night" spacecraft was launched.

The overall scale has been increased by ten times compared to the original version, and the comfort is even more incomparable.

The latest version of the Eternal Night spacecraft will be built on the ground, and when it is completed, it will be lifted into space with an anti-gravity engine.

The spacecraft is in the shape of a ring, and in the center of the ring is a huge Hall thruster, which can provide more than a million N of thrust for the ship in space.

The surrounding ring is composed of individual chambers, each of which has a complete life support device and a small ion propulsion unit for attitude support.

In appearance, this spacecraft is a bit like the smaller "Navigator" space station in the Wandering Earth world.

The spacecraft is powered by six molten salt reactors with a total output of more than two gigawatts, as well as a large number of nuclear fuel rods.

The crew can change nuclear fuel in space on their own, and coupled with the hibernation system in the spacecraft, the overall self-sustaining power of the "Eternal Night" spacecraft is more than 200 years.

As a result, the number of astronauts in the entire Lazarus program also needs to be greatly increased.

However, due to the danger of this plan and the problem of the astronaut training cycle, in the end, the space agency controlled the total number of people in the "Eternal Night" spacecraft to less than 100.

A lot of work will be done by the artificial intelligence in the spacecraft's main control computer.

Due to the expansion of the overall scale of the Eternal Night spaceship, the mission redundancy and various guarantees of the entire spaceship have been increased by more than 100 times compared with the previous spaceship.

Originally, the high-level leaders of the coalition government were unwilling to invest such huge resources in the "Eternal Night" spacecraft, but in the end, Pang Xuelin's words made the coalition government suddenly become the biggest supporter of the spacecraft.

His words were: "The Eternal Night spacecraft project could pave the way for the future Space City program." ”

……

After the spread of the wilt virus on Earth, it has become more and more unsuitable for human survival, so space has become the only way out for mankind.

After the breakthrough in anti-gravity technology, the Space City project is also on the agenda.

But before that, mankind had never carried out such a large-scale space project.

Because of this, the "Eternal Night" spacecraft has become a touchstone for the future space city project.

Realizing this, the United Governments of Mankind, composed of the three autonomous regions of North America, East Asia, and Europe, provided a surprising amount of resources to support the Lazarus Project.

Fortunately, after so many exercises in the science fiction world, Pang Xuelin has unusually rich management experience for this kind of super-large scientific project.

Coupled with his superhuman vision, after only one year of project demonstration and design, the spacecraft officially entered the engineering implementation stage.

……

Two years later, in a secret base belonging to the Space Administration, a ring-shaped spacecraft with a diameter of more than 500 meters stood majestically in front of Pang Xuelin.

The Hall Thruster, the main power system used for the spacecraft, is a cylindrical structure with a diameter of up to 50 meters, so the combination of the ring and the Hall Thruster will be carried out in space.

At present, the main structure of the Hall thruster has been launched, and through that launch, mankind has verified the state and stability of the anti-gravity engine.

Today, NASA will officially launch the main structure of the "Eternal Night" spacecraft.

With the order of the commander-in-chief of the scene, the steel structure supporting the Eternal Night spacecraft shook slightly, and a wave of fluctuations spread out.

In an instant, a flock of geese that had just passed over the spacecraft fell from the sky like headless flies.

Immediately after, the spaceship floated silently.

The ion thrusters in the twelve main structure cabins emitted a faint blue light, pushing the spacecraft silently into the sky.

The acceleration provided by the auxiliary power system was not large, and it was not until more than half an hour that the spacecraft slowly disappeared into the sky.

At this time, Brand quietly came to Pang Xuelin's side and said, "Pang, if this test goes well, you should set off in half a year." ”

Pang Xuelin nodded, did not speak, and his heart unconsciously became a little heavy.

In three years, Pang Xuelin has established a deep relationship with Chrissy and Little Murphy.

This time we are separated, and I don't know what year, month, and day we will see each other again.

"Pang, I'll give you half a year's vacation, and for the next half a year, go and accompany them."

"Thank you!"

Pang Xuelin turned his head to look at Brand and nodded.

……

On the way home from the test base, Murphy, who has always been lively, rarely became much more silent.

"Brother-in-law, do we only have half a year?"

"Pretty much." Pang Xuelin nodded and said, "In the past six months, you have been accompanying the old man more when you go home, he has actually always remembered you." ”

"I know."

Murphy turned his head to prevent Pang Xuelin from seeing his red eyes.

However, when they got home, the two became the same as usual, and did not let Chrissy and Oliver notice anything unusual.

In three years, little Murphy has grown a head again, and has become a ten-year-old slim little girl.

But it's still sticky to Pang Xuelin.

Who made Pang Xuelin spoil her the most.

But although the pet is petted, the little girl is well-behaved and cute, and her academic performance in school is also good, which is very likable.

Pang Xuelin even regarded her as the pearl of his palm, holding it in his hand for fear of falling, and holding it in his mouth for fear of melting.

In the evening, after the family finished eating, Pang Xuelin tutored little Murphy in his schoolwork, and returned to the bedroom, where Chrissy had already finished taking a shower and was wiping her wet hair.

Pang Xuelin went up to incense his wife, but was glanced at by Chrissy, stuffed the bath towel into his hand and said, "Stinky and baked, go take a bath for me." ”

"Yes, dear."

After taking a shower, as usual, it was a big battle.

At the end of the battle, Chrissy lay on Pang Xuelin's chest weakly and said, "My dear, how long are you going to stay when you come back this time." ”

In the past three years, as the deputy commander-in-chief of the "Lazarus" project, Pang Xuelin has traveled frequently to coordinate the construction of the "Eternal Night" spacecraft, and Chrissy has become accustomed to the days when Pang Xuelin treated his home as a hotel.

Pang Xuelin said with a smile: "The past two years have been busy enough, this time I applied for a long vacation from the bureau, and I can accompany you at home for at least half a year." ”

Chrissy's fingers were originally gently rounding Pang Xuelin's chest, and she couldn't help but hesitate slightly when she heard the words.

"What's wrong?"

Pang Xuelin lowered his head in surprise.

"It's fine."

Chrissy lowered her head, her eyes were like water, and she said, "Husband, I still want it." ”

……

If it weren't for the global mass extinction caused by the wilt virus, the company of his wife and children, and the quiet life, such a day would be like heaven for Pang Xuelin.

But now, the happier such days, the more tormented Pang Xuelin feels in his heart.

He vaguely felt that Chrissy already knew something, but Chrissy was reluctant to say it, and Pang Xuelin didn't know what to say.

The two carefully maintained this tacit understanding between husband and wife.

It's little Murphy, who is very happy day by day.

Dad was spending more and more time at home with her.

In addition to picking her up and dropping her off to and from school every day, on weekends, I often take her and her grandfather to go on field trips, picnics, kite flying, and games with my mother.

Sometimes my aunt will go with her.

This kind of life, in little Murphy's heart, is like a dream.

However, no matter how happy your life is, there will eventually come an end.

That evening, Pang Xuelin finally received a call from Brand.

After hanging up the phone, Pang Xuelin raised his head, looked at Chriss, who was busy in the kitchen, opened his mouth, and muttered, "Chrissy, I'll ...... tomorrow Going to go......"

Bang Dang –

The shovel in Chrissy's hand fell into the pot.

Tears kept rolling down Chrissy's fair face, Chrissy hurriedly wiped her tears with her hands, tried to smile and said, "Are you going back to work again?" Then I'll do it at night...... Cook venison, grilled fish steak, jam bread, corn salad...... Oh, by the way, the old man has a bottle of red wine hidden in the cellar, I'll take it out later......"

Chrissy tried to restrain her emotions, but as she spoke, tears began to fall like a burst.

"Chrissy!"

Pang Xuelin couldn't hold back, stepped forward quickly, and hugged his wife tightly into his arms.

"Woo ......"

The tight string in Chrissy's heart suddenly broke, and Chrissy could no longer control her emotions, and lay in Pang Xuelin's arms and cried.

Pang Xuelin just patted his wife's back gently, letting his wife's tears soak the clothes on his chest, his eyes were slightly red, and he couldn't say a word.

At this time, old Oliver walked down the stairs step by step, on crutches.

Three months ago, when Oliver went downstairs, he accidentally fell and broke his calf, and he still hasn't fully recovered, so he can only walk on crutches.

Looking at the couple hugging each other at the kitchen door, Oliver looked up and let out a long sigh.

At this moment, the sound of a car engine came from outside the door.

Chrissy, who was emotionally released, got out of Pang Xuelin's arms, wiped the tears on her face and said, "You also go and tidy it up, don't be found out by your daughter...... That girl...... That girl haunts you the most, and she will break down if she knows you're leaving......"

Pang Xuelin nodded and was silent.

After a while, Big Murphy took Little Murphy into the house.

"Daddy!"

Little Murphy put down his schoolbag, rushed towards Pang Xuelin at once, and kissed him fiercely on the face.

"Baby!"

Pang Xuelin held his daughter tightly in his arms, kissed his daughter's face affectionately, and after a long while, he slowly let go of Little Murphy.

"Brother-in-law, what's wrong?"

Murphy asked.

Pang Xuelin said: "I received a call from Brand, and we will report back to the bureau tomorrow......"

The expression on Murphy's face froze suddenly.

The dinner was unusually rich, but the atmosphere was somewhat solemn.

Even little Murphy faintly felt a hint of abnormality.

"Dad, Mom, what's wrong with you? Got into a fight? ”

Pang Xuelin was just about to answer, but Oliver on the side said: "Little Murphy, your father is going back to work tomorrow, and he may have to go on a business trip for a month or two, and your mother is not happy." ”

"Hee-hee, doesn't Dad travel a lot? I'm used to it. ”

Little Murphy laughed.

Oliver also smiled and said, "Yes, yes, Chrissy, you see you, you are too child-like, not even as good as little Murphy." Pang is not on a business trip once or twice, and he will be back soon. Come, let's toast and wish our family a reunion soon. ”

"Cheers!"

After eating, Oliver said, "Pang, you and Murphy come to the study, I have something to say to you." ”

Pang Xuelin and Murphy glanced at each other, and the two followed Oliver upstairs.

When he came to the study, Oliver said: "Pang, you and Murphy went here, and when you came back, I don't know what year and month it was." How difficult the space journey is, no one knows what lies behind the wormhole of Saturn. Oliver Sr. didn't have much to talk about in his life, and what I was most proud of was having two wonderful granddaughters. Chrissy is blue-hearted, calm and serious, Murphy is lively and cute, and has excellent talent. My two granddaughters are in your hands, and Murphy will follow you in the future, and you will have to take care of her, when you carry out the mission...... Best...... It's best to arrange some safer tasks for her, if something happens to her, the old man will go to hell in the future, and he will have to settle accounts with you! ”

"Grandpa!"

Murphy's eyes were red, and he couldn't help but cry.

Pang Xuelin said: "Old man, don't worry, even if I die, I won't let Murphy have an accident." ”

Old Oliver nodded and said, "Okay, good girl, come to grandpa, our grandchildren haven't spoken well for a long time." Pong, you go and accompany Chriss. ”

"Old man, then I'll go first."

When Pang Xuelin came out of the study, he saw Chrissy in Little Murphy's room, helping her with her homework.

Pang Xuelin also followed, and the family of three talked until Little Murphy went to bed, and the couple quietly withdrew from their daughter's room.

Back in the bedroom, as soon as Pang Xuelin closed the door, his waist was tightly hugged by Chrissy from behind.

Pang Xuelin turned around, and Chrissy had already kissed him.

It took a long time for the two to separate out of breath.

Chrissy said, "Honey, carry me into the bathroom, and don't sleep at night." ”

……

Six o'clock the next morning.

Pang Xuelin opened his eyes, and Chrissy was holding his arm tightly, sleeping deeply.

Chrissy insisted until four o'clock in the morning, and she couldn't hold on, but Pang Xuelin was very sober.

Outside the house, the sound of a car engine could be heard.

Pang Xuelin knew that this was the person who came to pick him up and Murphy.

Pang Xuelin gently pulled his arm out of Chrissy's arms, quietly got out of bed, changed his clothes, and then opened the bedroom door, looked back at Chrissy, who was still asleep, and then quietly closed the door.

What Pang Xuelin didn't know was that the moment the door closed, a line of tears rolled down from the corners of Chrissy's eyes.

Later, Pang Xuelin quietly came to his daughter's room, and little Murphy was still asleep, holding a huge teddy bear with a shallow smile on the corner of his mouth.

Pang Xuelin's heart was filled with an unprecedented tenderness, he stepped forward slowly, bent down and gently pecked his daughter's face, and then quietly exited his daughter's room.

Downstairs, Murphy was dressed and waiting, and Oliver was preparing breakfast for him and Murphy.

After breakfast, the two walked out of the house, accompanied by Oliver.

Murphy stepped forward and hugged Oliver Sr. for a long time before getting into the car.

Pang Xuelin also hugged old Oliver and said, "The space agency will settle you and Chrissy in the future, you must live well, we will come back soon." ”

Oliver said, "I'll wait! ”
