Cataclysmic Era: I can unlock the tech tree

Ling meticulously carried out the orders from Lü Yongchang and Fang Xu.

With the activation of the warp drive, the warp bubble was successfully generated, and the mobile experimental ship, which had been stationary in the vast universe, instantly disappeared from the images transmitted back by the probe.

They successfully entered a warp state and "disappeared" into the light-speed universe.

The real experiment began at this moment.

Inside the Earth-class laboratory, things quickly became busy.

……

"Current experimental ship speed: 1.1c!"

"Quantum communication is normal, tachyon communication device is operating normally!"

"..."

The somewhat noisy reports continued to echo in the laboratory.

Lu Yongchang slowly stood up from his seat, his eyes becoming increasingly sharp: "Begin compiling the tachyon information!"

As soon as the words were spoken, inside the experimental ship, under the control of the gravitational field, the rotation speed of the two miniature black holes changed slightly.

Meanwhile, the strong gravitational field created by the miniature black hole has also undergone some changes.

"The tachyon message has been successfully compiled!" an academician shouted. "The message has been successfully transmitted!"

……

Unlike emitting tachyon information, the way human civilization currently receives tachyon information is relatively simple—by observing the gamma-ray fluctuations released when tachyon energy dissipates, we can infer the frequency of the tachyon itself and thus analyze the information it carries.

After all, unlike tachyons, the gamma rays they release are observable in the slow universe.

Although tachyons are found throughout the universe, over a long period of time, the energy they carry has long been dissipated, and their own energy is almost zero.

Therefore, the gamma-ray waves emitted by tachyons are particularly noticeable in the observation instruments!

It was as blinding as a light bulb in a dark room!

However, this observation method also leads to another drawback.

Communication distance has become limited.

The current scope of tachyon communication in human civilization is precisely the range within which tachyons dissipate their energy to a level below the precision required for observation.

It is estimated to be around 1000 light-years away.

On a cosmic scale, this distance is nothing.

But for human civilization today, this is vast enough!

The methods to increase the tachyon communication range are also quite simple, and there are roughly two directions.

Firstly, the initial speed of tachyons should be slowed down as much as possible, that is, to allow them to carry enough energy to support a longer dissipation time.

Secondly, it increases the fleet's own observation accuracy.

Lü Yongchang prefers the second option.

The speed of a tachyon increases with the degree of energy dissipation.

This means that the speed of tachyons will increase over time!

In other words, as long as the observation accuracy is high enough, the communication range of tachyon communication is the entire universe!

……

Almost at the same time the academician spoke, Zero's electronic synthesized voice also sounded from the speaker.

"Successfully observed vacuum gamma-ray fluctuations!"

"Information recognition accuracy: AAAAA, deciphering information..."

"Information matching successful, confirmed as a tachyon message sent by our side."

After a brief wait, enthusiastic cheers erupted in the laboratory.

"Don't celebrate yet, it's not a complete success!" Lü Yongchang interrupted the cheers of the academicians. "Continue to increase the starship's speed to over 10c!"

As the starship in the holographic projection continued to increase its speed, the atmosphere in the laboratory gradually calmed down.

9.8c, 9.9c, 10c...

10.1c!

"Quantum communication has been interrupted."

A emotionless, synthesized electronic voice rang out, echoing throughout the laboratory.

Lu Yongchang showed no surprise whatsoever.

This situation was exactly what he had anticipated, and he had already made corresponding arrangements.

When the experimental ship enters the second-level curvature state, the experiment will be maintained by the ship's onboard computer.

After all, humans have only built one tachyon communication device so far. Once quantum communication fails, communication will become one-way.

Time ticked by, and the atmosphere in the laboratory gradually became tense.

"Successfully received tachyon information!"

The synthesized voice broke the tense atmosphere once again: "Message: Current speed 20c, I have exited the cabin, feeling good!"

Looking at the line of text projected on the holographic screen, Lü Yongchang was completely dumbfounded: "...???"

This scene is quite explosive even in the entire history of humankind.

"Who the hell put this information in there?"

"Ahem... Professor, it's me." He Bilin, standing not far away, chuckled and raised his right hand. "I was just trying to liven things up..."

Lu Yongchang took a deep breath, calming his inner urge to complain: "That was well done. Don't do it again."

In any case, the success of the tachyon communication experiment signifies a significant leap forward in the fleet strength of human civilization.

Therefore, Lü Yongchang had a big smile on his face when he was complaining.

Celebrations erupted once again inside the laboratory.

……

Earth year 3625.

After experiencing several interruptions in quantum long-distance communication, Lü Yongchang became acutely aware of a problem.

The miniaturization project for tachyon communication devices must be put on the agenda as soon as possible!

Small starships and probes are an important part of the fleet and must never become a weak link in the fleet.

Under his leadership, the Academy of Sciences spent several years successfully breaking through this technological barrier.

Thus, every starship and probe with reserved space for a tachyon communication module has successfully been equipped with a tachyon communication device.

The speed at which human civilization expanded its territory also instantly jumped to a new level.

To date, human civilization has mastered three galaxies surrounding the Kepler 452 galaxy.

Under Zero's control, the [Star Devourer] continuously mines the iron planets in these three star systems, providing the human fleet with a large amount of essential mineral resources.

To Lü Yongchang's regret, there are no habitable planets in these three star systems, and naturally, no extraterrestrial civilizations.

"Professor, what about the Sociology Department...?"

Fang Xu smiled wryly and knocked on Lü Yongchang's office door, reporting softly, "They asked me about that matter again."

"No!" Upon hearing Fang Xu's words, Lü Yongchang stopped his work impatiently. "Tell them that no trace of any primitive civilization has been found!"

"Forget about civilization, the fleet hasn't even seen a single insect!"

"Oh, right!" Lü Yongchang said as if he had just remembered something. "Well, some single-celled organisms have been discovered on a planet. Ask the Sociology Department if they're interested in those things."

"That's strange..." Lü Yongchang scratched his head vigorously, a look of confusion in his eyes.

"When we first left Earth, we encountered alien civilizations everywhere; there was no way to escape them."

"Now I'm going to look for them, but they've hidden themselves very well!"

"Tsk! What bad luck!"

Lu Yongchang looked at the brand-new desk in front of him with a depressed expression and complained in a low voice.
