Age of Cataclysm: I can light up the technology tree

Looking at the four big words on the monitor in front of him, Bai Yixuan suddenly broke out in a cold sweat.

He opened his mouth and asked with difficulty: "Professor..."

"What did you send?"

After saying that, he turned his head and looked at the porthole beside him.

Looking at the dead silver-white moon and the dark universe outside the porthole, his body trembled slightly.

At that moment, he even felt like he was being stared at by some terrifying existence!

The five teammates around Bai Yixuan were also in great fear.

This sentence "Hello, human" looked too terrifying.

Especially after Proxima Centauri sent a message to the earth, such a message was like dancing on everyone's tense nerves!

In just one or two seconds, the six people on the moon had even thought about the end of human civilization.

"What?"

Lv Yongchang's voice came, full of doubts and confusion: "Hello, human, isn't it these four words?"

In an instant, Bai Yixuan felt that his tense nerves snapped.

"Professor, can you explain why you chose to send these four words..."

"Do you know how many misunderstandings such a name will cause?!"

Even Bai Yixuan couldn't help but complain to the radio at this time: "I even thought that an advanced civilization came to my door!"

Lv Yongchang, who was in the command center, heard Bai Yixuan's complaints, and a strange look flashed across his face.

Facing the strange eyes of several researchers around him, he smiled and explained.

"Actually, I wanted to send hello world at first."

"Thinking that the Human Union has been established, I chose the four words hello humanity..."

As he spoke, Lu Yongchang's voice gradually became weaker.

Obviously, he also realized how much misunderstanding the four words he sent would cause.

"Ahem!" He cleared his throat and changed the subject directly, "So, when did you receive the message?"

"About one second before your voice sounded." Bai Yixuan answered honestly, "According to Yi's data, the exact time should be 1.26 seconds."

The moment Bai Yixuan's voice fell on the radio, applause rang out in the laboratory.

Looking at Mr. Tang who was smiling beside him, Lv Yongchang also showed a relieved smile on his face.

Success!

The ultra-long-distance communication technology, which symbolizes the most advanced technology of the first-level civilization, was firmly grasped by humans at this moment!

…

At the same time, in the central area of ​​the Milky Way.

An artificial planet quietly stayed in the boundless universe.

Unlike ordinary planets, this mechanical planet has no rotation, no revolution, and no tilt angle.

If you pass by this planet, you can't even feel any gravity!

It's as if this planet is just an illusory image!

It just stays quietly in the empty universe, showing its strength to the surroundings.

Inside the artificial planet.

"Sir, an unknown signal was found at the edge of the Orion arm."

A report attracted the attention of Sweeper 9527 who was sitting high up.

His visual organ shook slightly and looked at the instrument next to him.

Seeing the red dot on the instrument, a little white appeared on his originally blue skin.

That was the way their race expressed surprise.

"Hmm? The edge of the Orion Arm?"

"If I remember correctly, a low-level civilization should have been discovered there not long ago?"

As he spoke, he quickly mobilized his external memory storage device.

A few milliseconds later, he spoke again: "Huh... two civilizations are so close?"

"What did they send?"

The next moment, a light curtain appeared in front of Sweeper 9527.

Looking at the text on the light curtain, the vibration amplitude of Sweeper 9527's visual organs became more and more obvious.

"Tsk, another bug that just left its home planet..." Sweeper 9527 said impatiently.

"Sir, we..."

Faced with the inquiry of his subordinates, Sweeper 9527 casually glanced at the coordinates on the instrument: "Execute the cleaning procedure."

"Don't forget, not long ago, a seventh-level civilization of the Pastoral School fled there."

"According to the requirements above, any civilization that appears there must be cleared."

While speaking, he slid the application submitted by his subordinates: "A red dwarf star, or a first-level civilization... a star-eating device is enough to deal with them."

"Our war with the Pastoral School is far from over. Save some resources to avoid being held accountable by the above in the future."

At the same time, a sphere with black light appeared "out of thin air" next to the artificial planet.

The next moment, the sphere disappeared instantly.

"Sir, the star-eating device has entered curvature navigation."

...

Earth.

After the breakthrough of quantum long-distance communication technology, Zero immediately started the manufacturing task.

Countless robots and mechanical arms appeared continuously on the production line.

A large amount of smelted resources were transported to an altitude of 91,000 kilometers via [Jianmu] and [Babel Tower].

Then, these robots, mechanical arms and mineral resources entered the ten Luanniao starships through crawlers.

The construction plan of Mars City has begun!

Human Union Starship Base.

In a relatively remote dormitory.

"Hey... Zijie, when do you think we can drive a real starship?"

A voice with some sorrow sounded.

Zhao Zijie sat in his seat, silently looking at a textbook in front of him.

"On the Application of Sun Tzu's Art of War in Interstellar Warfare"

Hearing his roommate Gao Yang's complaints, his eyes moved slightly, moved his eyes away from the textbook, and chuckled: "What's the hurry?"

"Since we haven't entered hibernation, there must be a time to drive a starship."

"Instead of thinking about it, it's better to simulate a few more interstellar wars."

"Don't forget, when we leave the solar system and wake up again, we will have a war with the Proxima civilization."

Gao Yang's face was bitter, and he waved his hands repeatedly and said: "Zijie, don't say it."

"What interstellar war simulation class, I want to vomit when I think about it."

"Too difficult..."

Zhao Zijie smiled and was about to continue to persuade his roommate, but there was a quick and strong knock on the door.

Gao Yang on the side stood up lazily from the chair and prepared to go over to open the door.

"Gao Yang!"

Zhao Zijie looked more serious, and lowered his voice to call his roommate: "Wait, clean up the room, I'll go open the door."

Seeing his roommate's puzzled look, Zhao Zijie lowered his voice again: "This knock on the door may be Chief Qi."

Gao Yang's face changed slightly.

He did not doubt Zhao Zijie's judgment at all, and quickly turned around to clean up the slightly dirty dormitory.

The knock on the door sounded again.

Zhao Zijie hurriedly walked to the door and opened the dormitory door.

"... Chief Qi."

Looking at the middle-aged man with a resolute face in front of him, Zhao Zijie called softly.
