Cataclysmic Era: I can unlock the tech tree

Human fleet.

Zhao Zijie frowned.

"Professor, it seems they've changed their tactics."

He sent a message to Lü Yongchang via an EEG reading device.

Soon, Lü Yongchang's response appeared on the holographic projection in front of him.

"good."

"According to the data provided by Zero, the enemy's attack frequency has decreased significantly, and they are maintaining a considerable distance from our starships."

"It looks like..."

"It's like they're driving us away."

A glint of light flashed in Zhao Zijie's eyes.

Well said!

It's about driving them away!

Moreover, it was a purposeful expulsion!

As soon as he had a thought, the holographic projection in front of him rapidly enlarged.

On the star map, the white dots have completely blocked the blue dots' retreat, leaving only a clear path forward!

"It seems the enemy had already laid an ambush ahead."

"Zijie, what are you planning to do?"

Lü Yongchang sent another message.

Zhao Zijie frowned as he examined the star map.

According to the star map information, there was nothing unusual about the fleet's direction of travel.

Neither active detection equipment nor optical telescope arrays detected any trace of the enemy ship.

After deliberating for a long time, a ruthless glint flashed in his eyes.

"Use their scheme against them, and make an example of them."

In just eight words, he perfectly expressed his plan.

However, the risks involved are immeasurable!

Lu Yongchang frowned as he looked at the eight Chinese characters in front of him.

He wanted to object, but as the person in charge of the technology, he knew he couldn't interfere too much with the other party's decision.

therefore.

After hesitating for a moment, he sent a message to Zhao Zijie.

"Could you explain your reasoning?"

Seeing that Lü Yongchang did not directly oppose his plan, Zhao Zijie breathed a slight sigh of relief.

He rallied his spirits and quickly relayed the message to Lü Yongchang.

First, let's make a simple guess as to why they did this.

"It simply means that a more advanced fleet is waiting for us."

"There's a strong possibility that this is the flagship of the opposing civilization."

"Faced with this tactic, the safer course of action would be to change course and engage these warships in battle."

"However, in any case, we will eventually encounter their flagship."

"If we use the two-dimensional fragments to directly take down the enemy's flagship..."

Lu Yongchang's tightly furrowed brows gradually relaxed.

After a moment's consideration, he nodded.

"Do as you say."

The order has been issued.

The human fleet began to accelerate, rushing towards the only "path to survival"!

A few minutes later.

Lu Yongchang stared intently at the holographic image in front of him.

His pupils contracted sharply, and his breathing became rapid!

Zhao Zijie, inside another deep-sea submersible, had a similar expression!

There is no other reason.

The holographic projection displays images from an optical telescope.

The image shows a massive starship with a dilapidated exterior.

The starship is enormous; a rough measurement indicates it is tens of thousands of meters long.

Compared to it, even the Earth seems exceptionally small.

but!

That's not the point.

Even a starship from an advanced civilization couldn't have caused Lü Yongchang to lose his composure like this.

The key point is how this starship appeared!

几分钟前。

Because he was on guard, Lü Yongchang specifically pulled up the real-time footage from the optical telescope and observed the outer space in front of the human fleet with the naked eye.

The universe is incredibly deep.

Apart from the distant, faintly glowing stars, he found no trace of any starships.

For a moment, he even wondered if he and Zhao Zijie were overthinking things.

Could it be that the opposing civilization chose to retreat after discovering that the combat power of their fleet exceeded expectations?

This suspicion persisted until ten seconds ago.

Ten seconds ago, what lay before Lü Yongchang was still that vast, endless, dark universe.

But the next moment, a colossal object suddenly appeared in this vast universe!

And it blocked the human fleet's advance!

The way the starship appeared was extremely bizarre.

It's like... canceling invisibility and suddenly appearing in front of humans!

And the identity of this 10,000-meter-class warship...

Without a doubt, it must be the flagship of the opposing civilization!

at the same time!

"Beep! Beep! Beep!"

The piercing alarm sounded again throughout the command center!

"alarm!"

"Enemy ship radar signal detected!"

Signal strength: Extremely high!

Current distance: 10 light-seconds.

As the optical telescope detected the image of the enemy flagship, the active detection equipment also detected the enemy's radar signal.

A strange phenomenon occurred.

"Enemy ship radar signal detected, distance: 11.1 light-seconds!"

"mistake!"

"Enemy ship radar signal detected, distance: 9.99 light-seconds!"

"mistake!"

"..."

A series of bright red alarms flashed across Lü Yongchang's screen.

Lü Yongchang was stunned and stood there.

This……

What's going on?

He glanced at the holographic image in front of him one last time.

The enemy warship remained stationary, making no move, while emitting incredibly powerful full-band detection signals to demonstrate its presence to humanity.

According to observation data from optical telescopes, the distance between the human fleet and the enemy ships is constantly decreasing.

The second distance data of 9.99 light-seconds clearly matches this observation result.

So... what was the first signal?

The other side only had one flagship, and it didn't make any moves, but two radar signals appeared at different distances.

What is this?

Suddenly, a chilling thought popped into Lü Yongchang's mind.

"zero."

"Set the opponent's speed to faster than the speed of light and recalculate!"

As soon as Lü Yongchang gave the order, the error messages that kept flooding the screen disappeared instantly.

"professor."

"Calculations show that the enemy flagship is moving at 1.1 times the speed of light."

Although he was mentally prepared, he still gasped deeply when he saw the result... Deep Sea Liquid.

Faster-than-light travel technology!!!

It's faster-than-light travel technology!!!

Lu Yongchang's gaze toward the holographic image suddenly became complicated.

Fear and panic were mixed with a hint of fanaticism and greed.

If we could capture this warship...

"Unidentified communication request detected."

"Signal source: 9.98 light-seconds ahead."

Zero's voice interrupted Lü Yongchang's thoughts: "Accept?"

After a moment's hesitation, Lü Yongchang nodded vigorously: "Received!"

[Unknown technological civilization, halt your advance!]

[Hand over 80% of the supplies and all the technological data, and you can leave safely!]

Because the communication information included dictionary information, Zero quickly completed the interpretation of the information.

The moment the information was deciphered, the enemy fleet following behind the human fleet accelerated to the scene and surrounded the human fleet.
