Cataclysmic Era: I can unlock the tech tree

Decades later.

Earth year 9900.

On the edge of the Andromeda Galaxy, within a small galaxy.

As the output power of [Kuafu] gradually increased, the small universe port gradually became clearer.

then……

The yellow dwarf star located at the center of the Hang Seng galaxy slowly disappeared into the vast universe.

When the central star disappeared, the planets continued to maintain their original orbits.

But over time, gravitational waves gradually spread to every planet.

These planets, from the inside out, fly outwards from the star system along the tangent direction.

The normally orderly galaxy became disordered at this moment.

At this moment, the brand-new human fleet shot out like a sharp arrow from the chaotic Heng star system and sped towards the depths of the Andromeda star system!

Unlike in the past, the human fleet now has a mark "stamped" on the most conspicuous position on the hull - the mark of the Silicon Alliance!

After nearly a century of rest and recuperation, the human fleet has once again returned to the state it was in when it left the Milky Way.

The microcosm already contains five yellow dwarf stars in their prime.

The most important thing.

After a century of round-the-clock searching, He Bilin and a group of academicians have successfully found the next destination for human civilization—a binary black hole system.

……

AGBH-01, AGBH-02.

These are two supermassive black holes located in the Andromeda Galaxy.

Starting hundreds of millions of years ago, these two black holes began to converge, and today, they are finally about to achieve their goal.

This is a momentous event about to occur in the Andromeda Galaxy that will attract the attention of advanced civilizations.

Almost all advanced civilizations in the Andromeda Galaxy have focused their attention on these two black holes.

The reason...

Simply put, these are two massive black holes with extremely large accretion disks.

When the two collide, they will create a giant firework display that will light up the entire Andromeda Galaxy!

At the same time, the gravitational wave effect caused by the black hole merger will directly affect the entire Andromeda Galaxy and even the surrounding galaxies.

For most interstellar civilizations, this would be a feast—a feast to glimpse all sorts of amazing phenomena.

The two black holes are approximately 15 light-years away from the human fleet.

According to observations, these two black holes will approach each other and collide within 500 years!

This means that human civilization must reach that binary black hole region within 500 years.

Fortunately, 15 light-years isn't that far.

Although the Kuafu can only travel at a speed of around 800c.

But this is more than enough – without any repairs, it would only take the fleet 187 years to reach the region of the two black holes.

However, considering the various unexpected situations that might be encountered along the way, under Lü Yongchang's orders, the fleet set off early and headed directly towards the target area.

……

Within the Human Union's microcosm, [Earth].

As Lü Yongchang was pondering the mysteries hidden within the binary black hole system, a holographic projection emitting a yellow glow suddenly popped up in front of him.

At the same time, the electronic synthesized sound of zero also rang out.

"Professor, the fleet has received a tachyon broadcast from an unknown source."

"It includes dictionary information."

Upon hearing this, Lü Yongchang frowned immediately.

Tachyon broadcasting is an advanced technology in tachyon communication.

The basic principles are similar; the only difference is that the broadcasting frequency is higher, it consumes more energy, and covers a wider area.

Tachyon broadcasting is indeed a good technology when the exact coordinates of the recipient are unknown.

but……

Who would send out a radio broadcast in such a high-profile manner?

Generally, tachyon broadcasts are released on specific frequency bands and are subject to various sophisticated encryption methods.

This form of indiscriminate tachyon broadcasting caught Lü Yongchang's eye—there had never been such a thing in the Milky Way!

It's like a loudspeaker at the village entrance.

The information it broadcasts can be heard by all people with sound hearing—corresponding to indiscriminate tachyon broadcasting, the audience is those civilizations of level five and above that have mastered tachyon communication technology.

"Try translating it."

Lu Yongchang stopped what he was doing and looked at the holographic projection in front of him with great interest.

[...The 7463rd tachyon broadcast from the Andromeda Galaxy.]

The merger of the AGBH-01 and AGBH-02 black holes is less than 500 years away.

[This may cause a large-scale gamma-ray burst and gravitational wave anomalies. Civilizations residing within two thousand light-years of the merging region are advised to prepare for the impact.]

[The above information comes from the neutral faction. Please forward it to other civilizations to avoid unnecessary casualties and losses.]

[The following frequency bands are for civilized exchange established by neutral parties: ...]

[Broadcast complete. Next broadcast scheduled for...]

Lu Yongchang opened his mouth slightly, staring blankly at the holographic projection in front of him.

After a long silence, he uttered a few words with a strange expression: "Weather forecast?"

"Whoosh!"

The office door opened, and a series of hurried footsteps could be heard.

"Yongchang, I heard the fleet received an indiscriminate tachyon broadcast from the neutral faction?!"

Before the people arrive, the sound comes first.

Hearing the strong curiosity in Fang Xu's voice, Lü Yongchang rolled his eyes in annoyance.

"You're really well-informed!"

"I had just finished reading the message when you arrived."

Fang Xu chuckled awkwardly and quickly turned around to drag the person waiting at the door inside: "I heard it from He Bilin!"

Faced with Lü Yongchang's gaze, He Bilin, who was being held tightly, looked completely bewildered: "???"

"I……"

Lu Yongchang sighed helplessly and picked up the water glass on the table: "You're here just in time."

"Please sit down, everyone. Let's analyze the information in this radio broadcast together."

"By the way, does anyone else know about this?"

As he spoke, he lowered his head, blew on the water glass, and took a sip of the energy supplement inside.

Since his body modification got stuck in the middle, his energy needs began to increase day by day, and his original tea was replaced with Dr. Wen's specially made energy supplement.

He Bilin and Fang Xu's expressions both turned strange at the same time.

"this……"

"Why don't you ask around and see if there's anyone else who doesn't know about this?"

Lü Yongchang: ? ? !

……

This interstellar version of the "weather forecast" tachyon broadcast has attracted the interest of countless academicians.

no way.

After awakening, the human fleet was either facing overwhelming adversaries or busy traveling, and had no stable resource supply or research environment.

Of course, for human civilization today, with no breakthroughs in fundamental theories, only some minor, everyday technologies offer hope for breakthroughs.

These are the jobs of researchers, and the academicians are too embarrassed to take away their jobs.

Furthermore, by joining the silicon-based alliance, the "immediate concerns" of human civilization have been properly addressed.

then……

This period of travel became the most leisurely time for the Academy of Sciences of the People's Federation, without exception.

As the saying goes, "Looking for grass seeds in a crack in a rock"—it's just a waste of time.

Having finally seen something new, the group of academicians left the laboratory and headed towards Lü Yongchang's office.

First came Fang Xu and He Bilin, followed by a group of idle Class I academicians.

Seeing that the office was about to be overcrowded, Lü Yongchang had no choice but to change his work location to the [Earth] command center.
