"Murphy, why are you here?"

Pang Xuelin was a little surprised.

Murphy said: "Brother-in-law, I can't sleep, I want to talk to you." ”

Pang Xuelin hesitated, turned sideways, and said, "Come in and talk." ”

With that, he went to pour Murphy a glass of water, handed it to Murphy and said, "It's going to leave tomorrow, are you worried about the next adventure plan?" ”

Murphy shook his head, took a sip of the cup in both hands, and remained silent.

Pang Xuelin said: "You don't have to worry too much, half a year after you set off, I will also set off, when you don't dare to go deep into Planet 5 alone, you can wait for me in the synchronous orbit of Planet 5, and after I finish the exploration of Planet 6, I will drive the shuttle out to meet you, and we will go to Planet 5 to take a look." ”

Murphy raised his head, his blue eyes stared at Pang Xuelin without blinking, and Pang Xuelin was a little hairy.

"Murphy ......"

Pang Xuelin wanted to say something more, but Murphy suddenly stepped forward and blocked what Pang Xuelin wanted to say next with his red lips.

After a long time, the two parted breathlessly.

"Murphy, we ......"

Murphy blocked Pang Xuelin's mouth with his hand and whispered in his ear: "Pang, you should know the danger of our operation, I don't know if I can come back alive after this departure." I'm not afraid, I'm just unwilling, I'm not willing why I haven't grown up when I met you...... I love you, Pang ...... Can we make our last night together feel what it's like to be loved? ”

Pang Xuelin's hand, which had been blocking Murphy, gradually loosened, and he stretched out his arms and hugged Murphy into his arms.

Soon, the bedroom light dimmed, and a faint cry of pain from the girl was heard.

Early the next morning, Murphy, accompanied by Pang Xuelin, entered the hibernation chamber in the shuttle.

The Eternal Night then ejects the shuttle, which begins a long journey that will last fifteen years.

……

Half a year later, Pang Xuelin completed his last video call with Chrissy and Little Murphy.

Chrissy in the video has quietly grown crow's feet at the corners of her eyes, and little Murphy is also fifteen years old and has grown into a slim girl.

Perhaps inherited from Pang Xuelin's excellent genes, Murphy Jr. has completed the entire high school course and was admitted to one of the best science and engineering universities in this era.

"Chrissy, Murphy, I'm about to embark on a voyage that will last fifteen years, and I will be in hibernation for most of this voyage, and maybe when I wake up again, little Murphy may have children, and I may also be a grandfather."

"Chrissy, I'm sorry, I owe you all my life. But please trust me, no matter what, I will come back to you and be with you all the time......"

"Murphy, it's good that you're growing up, Dad is really happy, remember to take good care of Mom in the future...... I love you ......"

After the five-minute video was recorded, Pang Xuelin entered the hibernation chamber of a shuttle and began to officially enter the hibernation state.

And the video he recorded will not be able to be transmitted back to Earth until a year later.

Pang Xuelin set sail.

……

July 2068 AD.

Pang Xuelin suddenly opened his eyes, and the soft voice of artificial intelligence Tass sounded in his ears: "Captain Pang, hello, I am your personal assistant Tas." You have been hibernating for fifteen years, two hundred and three days, fourteen hours, twenty-three minutes, and fifteen seconds. It will take another month to reach your destination, and over the next month, I will help you slowly get back to working as usual. ”

"Tass, thank you."

Pang Xuelin struggled to climb out of the hibernation warehouse, slowed down for a long time, and then crawled to the shower to take a shower and change into clean clothes.

Then he went to the porthole and looked out at the giant planet that was as red as the sunset on Earth.

The data shows that the red giant star is 200 million kilometers in diameter and has a mass eight times the mass of the Sun.

As its core shrinks and its shell burns, its internal temperature continues to rise uncontrollably, and at the same time, along with the huge size of the red giant, the red giant's surface area increases, its surface gravity decreases, and the density of its surface air decreases.

The increasing internal radiative pressure drives the solar wind to intensify rapidly, carrying away large amounts of gas that can affect the mass of red giants.

This process will continue uncontrollably over hundreds of thousands of years, because as the gas escapes, the star becomes less massive, the gravitational pull becomes smaller, and it becomes easier to escape.

The end result is that all stellar material except the core is thrown out in a stellar wind, leaving behind a degenerate core and outer layer of gas. We call them white dwarfs and planetary nebulae.

According to current observations, the red giant star has at least 500,000 years to live.

This is still quite a long time for human civilization, which has a history of less than 10,000 years.

Pang Xuelin returned to the bridge and began to check the computer data inside the shuttle, and then he asked, "Tarth, report on the specific situation of the nine adventure teams of the Lazarus Project in the past fifteen years." ”

"Okay, Captain Pang."

"Planet 2 Explorer Carrick and Planet 3 Explorer Anthony have both successfully completed their missions and are still on their way back to the Eternal Night spacecraft. Both Carrick and Anthony are in hibernation. Planet 2 has the basic conditions for life to inhabit, and even the interior of the planet has some primitive life. However, the gravitational acceleration of this planet is 2.5 times that of the Earth, and there are certain problems for ordinary humans to walk on this planet, so it is not suitable for human life. ”

"Although Planet 3 has water, the interior of the planet is full of frozen clouds and a large amount of ammonia, and the internal environment is also unsuitable for living things."

"The Planet 4 mission shuttle crashed into a wandering meteorite in the middle of the flight, and Ms. Cassie died, and the mission failed."

"Planet 5 mission Ms. Murphy landed on Planet 5 a month ago, but no information has been released......"

"Planetary mission shuttles 7, 8, 9, and 10 have not yet arrived in the mission area, and the crew is in hibernation......"

……

Pang Xuelin's heart gradually sank.

Nine expeditions, missions 2 and 3 were successful, but neither planet was suitable for human survival.

Before Four could reach his goal, he declared defeat.

Murphy did not send any news back after entering Planet Five, and his fate was uncertain.

He was left with four other ships, all of which were still on their way.

"Hopefully Murphy will be safe and well, and the other groups will be well."

Pang Xuelin said secretly in his heart, and after a moment of silence, he asked again: "Tas, in the past fifteen years, has there been any news from the earth?" ”
