"Brother, you should have a girlfriend."

"I think Shanshan is good. Sometimes she is tired of seeing me by your side, and her eyes are so envious. Don't tell me you don't know, she has loved you since she was a child."

"If you don't like Shanshan, that's fine. I'll introduce you to your classmates. There are a few foodies among them. It's completely easy to capture their hearts with your skills."

"Tsk, what's the distance between college students? So what about college students? In this era when college students are walking all over the ground, in my heart, they are not too different from you."

The night sky was like washing, and amid the beautiful sound of insects, clouds sat at the door of the shop and kept nagging.

After responding, Yunhai prepared the ingredients for the next day, and his eyes were filled with pampering when he looked at Yun Duo from time to time.

"Brother, college is not fun at all."

"I really want to accompany you in Yangshan every day, so that you won't have that hard work every day."

With a heartache expression on his face, Yunduo picked up a tissue and wiped the sweat from Yunhai's forehead.

"Brother, I miss my father and mom."

"I dreamed last night that our family sat together for dinner."

Yun Duo, who woke up from crying in the middle of the night, grabbed the hand of Yunhai who was running hurriedly and sobbed.

"I said, brother, you should worry about what you are doing. You really don't have to worry about my things now."

"Don't worry, no matter whether the love letter I received can hold half a sack, I have never opened a single one."

"When will you find me a sister-in-law? Let's talk about my affairs again."

Yun Duo said with a playful smile on his face.

…………

…………

Things I have always refused to think about, and when I calm down and try to recall, the scenes of the past are like tides that flood the sea of ​​clouds.

Yun Duo, his only remaining blood relative in this world.

Her laughter, her quarrel.

Her crying, her pretty.

The girl he once was willing to protect with all of her, everything completely occupied his consciousness.

So much so that after half an hour, Yun Hai recalled everything about his and Yun Duo's life.

A life planet can be turned into a dead star in the shortest time.

It can also easily destroy a civilization, just like the "Saint Zagali civilization" that is far more powerful than the "Earth" human civilization.

It can even violently destroy a planet and completely destroy it.

As the master of the alien, he had become bloodthirsty, cruel, violent and ruthless outside the sea of ​​Yun Hai for a time.

However, when he opened the dusty memory, he knew that some things would never change.

Just like his inseparable attachment to the "earth", just like his family affection for the clouds that will never change.

"I didn't remember the key thing, did I think of Yunduo?"

If you want to talk about the people who know the sea of ​​clouds best, except Yunduo is definitely Yunyue.

Feeling his violent emotional fluctuations, Yun Yue immediately guessed, but she floated over from a distance and asked during the spiritual exchange.

Shuran nodded, Yun Hai, who had nothing to hide in front of Yun Yue, did not speak.

"You miss her, and I miss her, too."

"If you miss her, then find a way to find the earth as soon as possible."

"We will see her when we find the earth."

There is no good way to comfort me in this kind of thing, so Yun Yue had to tell the truth.

Still nodding silently, the sea of ​​clouds fell into memories again.

If he remembered correctly, he remembered that Yun Duo suddenly became interested in astrophysics when he was a sophomore.

When she was in her sophomore year, a documentary about the universe produced by the United States became popular all over the world.

Yun Duo is no exception. After watching that documentary several times, she lost in the beautiful starry sky of the universe and began to collect more documentaries and information about the universe on the Internet and watched it with relish.

Yunhai doesn’t like watching movies, and he bought the only desktop computer at home because of Yunduo’s learning.

Although after Yunduo went to college, he wanted to buy a laptop for Yunduo repeatedly, Yunduo just refused.

So, after finishing work at night, the bored Yunhai had to accompany Yunduo to see those things.

"Humans are absolutely impossible to be the only civilization in the universe."

"What's ridiculous is that most people think we are the only ones in the universe."

"Brother, do you know? There are hundreds of billions of stars like the sun in our Milky Way."

"The distance between the earth and the sun is moderate and there is water, so humans are lucky to be born."

"However, there are so many stars in one Milky Way alone. I don't know how many planets meet the same conditions on Earth. Who knows which planet has other civilizations on it?"

"The universe is really too big, so big that we can never imagine."

"Brother, do you know that our Milky Way has always been considered a vortex galaxy, but the United States finally confirmed that it is a rod-rotary galaxy."

"You looked at me with innocent eyes again, okay, I know you don't know the difference between a vortex galaxy and a rod-rotten galaxy."

"Let's change the topic. The Milky Way is a flat sphere, which has a huge disk structure."

"This disk consists of a bright and dense core, two main spiral arms and two unformed spiral arms."

"Our sun is located on an Orion arm of the Milky Way, and the distance from the center of the Milky Way is about..."

As the memory continues, more pictures slowly unfold in Yunhai’s mind.

When the memories came here, Yunhai suddenly woke up.

"The solar system is located on one of the Milky Way's arm's Orion's arm."

"It is about what distance from the center of the Galaxy... is it..."

The buzzing sounded in my mind. Yun Hai knew very well that he had found the key, but at the same time he was stuck in the most critical place.

He knew very well that if he could recall Yun Duo mentioned this key number at that time, the location of the "earth" would be clear immediately.

However, even though he racked his brains, he couldn't remember at least how much the number was.

Emotions gradually became irritable.

The more you are confused about a certain number, the more you can't remember the sea of ​​clouds, and you have a very urge to go wild.

When Yun Duo's face appeared in his mind again, he quickly calmed down.

Irritability or irritability is of no use.

"The universe is so empty."

"Brother, the constant system closest to our solar system is Proxima Centauri."

"Do you know what this closest distance means? I even need about two more months to go to Proxima Centauri just in such a long time."

As he calmed down, more information began to emerge in his mind.

"Four light years...not right, it's four-point two light years."

"Proxima Centauri, the closest Proxima Centauri to the solar system, is around 4:2 light-years away."

Finally remembering a key number, he rolled on the surface of the star system excitedly, then brought a large piece of slurry to the sky, flying straight towards the home star of the "Saint Zachari Civilization".
