Age of Cataclysm: I can light up the technology tree

[Earth].

The office was dark without lights on.

Only the faint blue light of the holographic projection illuminated the surrounding environment.

A looming figure sat quietly behind the desk, with his elbows on the desk, silently watching the rapidly flashing words in the holographic projection.

Suddenly.

Perhaps because the position of [Earth] had changed slightly, a ray of light from the main star Gliese 555 shone directly on the porthole of the office.

Through the porthole, this warm light instantly dispelled the cold darkness in the office.

"Professor, the final candidate has been determined."

At the same time, the electronic synthesized sound echoed in the office.

"Okay."

The figure behind the desk moved and squeezed out a syllable with difficulty.

Then, under the light of the main star, the slightly brighter office fell into silence again.

Lv Yongchang stared at the name slowly moving in the holographic projection, and closed his eyes in some pain.

"Professor, Academician Su Yutong is here."

"Let her go back." Lv Yongchang's weak voice sounded, "Don't open the door..."

"Bang! Bang! Bang!"

The dull knock on the door interrupted Lv Yongchang's words.

"You go back." Lv Yongchang took a deep breath, cheered up a little, and shouted loudly.

"No!" Su Yutong's voice was slightly out of tune through the heavy hatch, "You have been in the office for three days!"

"..."

No response.

In the office, Lv Yongchang was still staring at the names in the holographic projection in a daze. He tried to remember all these names in his mind.

But, with a billion names, even his enhanced brain could hardly handle such a job.

"Don't forget, you are the chief scientist of the Human Union Academy of Sciences!"

The voice outside the door suddenly became stern: "If you fall, what will happen to the remaining billions of humans?!"

Lv Yongchang trembled slightly, but still did not speak.

"...I'll leave the food at the door. No matter what, you have to eat something."

Su Yutong's voice softened a little: "Human Union, there is still hope."

"I...I know."

Lv Yongchang's eyes were slightly red, and he whispered softly.

"Professor, Academician Su Yutong has left."

The moment the electronic synthesized sound sounded, Zero's virtual image slowly emerged beside him: "Your food was left at the door."

"...Help me bring it in."

Lv Yongchang's eyes dimmed, and he sighed again and whispered: "She is right, Human Union, there is still hope."

"We can't live up to the sacrifices of these one billion people."

"Click."

The sound of the door opening sounded, and a robot walked towards the office door under Zero's control.

Just as Lv Yongchang reached out and gently patted his cheek to cheer himself up a little, a message jumped out in front of him.

[Communication Request]

"Professor, a communication request was sent from the direction of Proxima Centauri."

"Do you want to receive it?"

Lv Yongchang put down the food he had just opened in his hand, and frowned slightly.

"A communication request from the human civilization of Proxima?"

Looking at the information flashing rapidly in the holographic screen, Lv Yongchang felt a jolt in his heart.

It's really one wave after another.

At this critical moment, I don't know what happened to the human civilization of Proxima.

A trace of imperceptible sadness flashed in Lv Yongchang's eyes: "Connect it."

...

17.55 light years away, Proxima Galaxy.

The light of the main star Proxima is very dim, and it is very difficult to dispel the darkness in this star system.

Proxima b.

Since hundreds of years ago, it has gradually become a silvery-white frozen planet.

One satellite after another silently revolves around this planet.

In the distance, a huge [Ray] starship slowly approached.

It came from the gas giant planet in the Proxima Galaxy to replenish fusion fuel for the few remaining surface cities on Proxima b.

Time is like a knife. Hundreds of years have left a very strong mark on [Ray].

But it still follows the original program and travels back and forth between the two planets without any effort.

Proxima b, Central City.

The roads, facilities and buildings in the city are all covered with a sense of heaviness brought by the passage of time.

The Central City has not changed for hundreds of years.

Not only the Central City, but also the surrounding cities have hardly changed in the past hundreds of years.

Proxima Human Parliament Building.

"Ren Feng, you are looking for me?"

A familiar voice came from an office deep inside.

Behind the desk, a middle-aged man with gray hair had a faint bitter smile on his face, waved his hand gently and said: "Zhengqing, sit down."

"Do you remember what I said to you at that time?"

Zhang Zhengqing's breath was slightly choked, and the relaxed expression on his face instantly became solemn.

He was silent for a moment, then nodded gently: "Of course I remember."

Zhang Zhengqing looked at the middle-aged man in front of him with a complex expression: "Have you... thought it through?"

Ren Feng did not respond to Zhang Zhengqing's question immediately, but raised his hand to operate the holographic projection beside him.

"Take a look."

He skillfully called up a document and displayed it in front of Zhang Zhengqing.

"This is the latest document from the Human Fleet."

Zhang Zhengqing glanced at Ren Feng suspiciously, and then focused his attention on the holographic projection in front of him.

The moment he saw the title, he suddenly widened his eyes.

"Broken...Broken Tail Plan?"

These four words immediately made him have bad thoughts.

He didn't have time to think about it, nor did he have time to ask, he just swiped the holographic interface and read it carefully.

"..."

"Crazy, Professor Lu is crazy!"

Zhang Zhengqing's hands trembled slightly, and he murmured in a low voice: "One billion people, this is one billion people!"

"Sacrifice them like this?!"

"For the survival of more people." Ren Feng smiled with relief and whispered, "They did the same thing at the beginning."

Zhang Zhengqing's voice suddenly paused.

He knew what Ren Feng meant by this sentence.

More than two hundred years ago, when the disaster struck, when the surface cities of Proxima b were in chaos, those old people also voluntarily gave up the chance to survive.

Recalling the scene at that time, Zhang Zhengqing's stiff face suddenly softened a little.

"Ah..."

"Maybe this is the inheritance of mankind."

"What a pity..." Zhang Zhengqing murmured with a sigh, "In today's Proxima human civilization, there may not be many people who have this kind of inheritance."

Ren Feng was silent for a while, and then said in an extremely firm tone.

"It doesn't matter."

"It's enough for us to have it."
