Cataclysmic Era: I can unlock the tech tree

one second.

Two seconds!

Three seconds!!

The red signal indicator continued to flash slowly in the projection.

Lü Yongchang's expression darkened slightly.

Failed?

What went wrong?

Suddenly, the red signal indicator stopped flashing and turned green under everyone's watchful eyes.

"Detector signal has been restored."

At the same time, near the huge four-dimensional cavitation bubble, the probe was seen again slowly retreating!

A burst of enthusiastic applause erupted inside the Dimension Research Center!

As he breathed a sigh of relief, a faint smile appeared on Lü Yongchang's face.

The detector's ability to safely enter and exit a four-dimensional cavitation bubble is an excellent start!

"Data transmission complete."

The sound of Zero's electronic synthesized voice cooled down the enthusiastic atmosphere inside the Dimension Research Center slightly.

What exactly is four-dimensional space like?

The answer to this question is finally about to be revealed!

The image in the holographic projection flickered slightly, having been switched to the perspective of one of the detectors.

……

As the probe continues to advance, the increasingly thin cosmic membrane of the four-dimensional cavitation is also being magnified.

Lü Yongchang could even clearly see the complex fluctuations of the cosmic membrane—the starlight coming from afar was constantly changing.

Time passes little by little.

Finally, the detector touched a four-dimensional cavitation bubble!

Swish!

Perhaps because the assimilation effect of the universe greatly weakened the "protective ability" of the four-dimensional cavitation, the probe entered the four-dimensional cavitation very smoothly.

It was a bizarre and fantastical world.

Not far away, there was a point of light radiating a dazzling glow.

As the viewing angle changes, the size of the light spot also changes dramatically.

It sometimes occupies the entire holographic projection, and sometimes becomes as small as a sesame seed.

This is an impossible scenario in a three-dimensional universe!

"This...could it be a star?"

Looking at the various data displayed on the side of the holographic projection, Lü Yongchang hesitated and made guesses.

The detector's camera continued to rotate.

Beside that dazzling spot of light were planets.

Like the points of light, the size of these planets also changed dramatically with the change of viewing angle.

Under the camera's view, each planet appeared as if it had been subjected to a severe attack, looking utterly devastated.

Lu Yongchang had gained some confidence in his earlier guesses.

It appears that the probe has entered a galaxy that exists in four-dimensional space.

Good luck.

Having a specific research subject is always easier than conducting research out of thin air.

As the camera's perspective continued to change, Lü Yongchang successfully observed a three-dimensional object in four-dimensional space—a detector of human civilization.

It's completely different from the detectors we see in three-dimensional space!

If the camera's viewpoint remains stationary, these detectors resemble a meticulously designed blueprint—every detail inside the detector is clearly reflected on a cross-section.

Various precision parts, intricate energy pathways...

In four-dimensional space, a camera originating from three-dimensional space can only observe the cross-section of a three-dimensional object.

However, as the camera's perspective slowly moves, this cross-section also moves accordingly.

After scanning the "circle," the complete internal structure of the detector was clearly revealed to everyone—countless cross-sectional views from different angles were pieced together to form a complete entity.

In four-dimensional space, there are no secrets for three-dimensional objects!

next second.

Driven by the self-running program, the probe began to retreat "cautiously".

In order to avoid touching that "strange" fourth direction, the detector needs to perform a lot of calculations for every step it takes.

After a few seconds, the screen returned to the familiar universe.

……

Inside the Dimension Research Center, all was quiet.

The short video footage brought an unprecedented shock to the academicians present.

"This is four-dimensional space..."

He Bilin, standing to the side, muttered to himself in a daze, "This is too... too amazing."

"No, this is definitely not the whole picture of four-dimensional space."

Lu Yongchang's words interrupted He Bilin's exclamation: "Even in three-dimensional space, the images captured by a camera have great limitations, let alone in four-dimensional space."

"Want to know the full picture of four-dimensional space..."

Fang Xu's heart skipped a beat.

Why does this dialogue feel so familiar?

Memories that had been dormant deep in my mind suddenly surged up.

In my memory, the scene of Lü Yongchang taking off in the "Xuan Nu No. 1" is like it happened yesterday.

Fang Xu suddenly felt like he couldn't breathe.

He asked Lü Yongchang in a strained voice, "I said..."

"You don't want to go and see the fourth dimension for yourself, do you?"

Before Lü Yongchang could speak, He Bilin's eyes already lit up with excitement: "Professor, is...is this really possible?"

Not only He Bilin.

A commotion broke out throughout the entire Dimension Research Center, with every academician casting expectant glances at Lü Yongchang!

They have studied dimensions for centuries, but have never actually seen a real four-dimensional space.

They find it difficult to imagine a real four-dimensional space in their minds and can only describe that magical space through countless complex formulas.

And now, an opportunity to witness four dimensions firsthand is right in front of you!

At this moment, one can only imagine the feelings of the academicians!

If I hear the Way in the morning, I can die content in the evening!

"What are you thinking about?"

Lu Yongchang replied without hesitation, "Of course not!"

As the light in the academicians' eyes slowly faded, Lü Yongchang added somewhat helplessly, "At least not now."

"It is too dangerous to enter the fourth dimension before fully mastering the technology of dimensional ascension."

"Alright, alright." Seeing the academicians' excited expressions, which seemed to have been rekindled, Lü Yongchang waved his hand. "Do you think I don't want to go and see the fourth dimension?"

"Study it as soon as possible; anything is possible, provided it is safe to do so."

"Zero, control the detector to perform the second exploration mission."

For the academicians, Lü Yongchang's words were more effective than any pep talk.

The academicians, who were still immersed in their imaginations, returned to their posts and devoted all their energy to their research work.

"Hello!"

Fang Xu tugged at Lü Yongchang's sleeve, lowering his voice anxiously, "Yongchang, are you crazy?"

"What if something unexpected happens..."

Lü Yongchang chuckled and shook his head.

"What is the ultimate goal of our research into dimensional ascension technology?"

He answered his own question: "To elevate the starship to a higher dimension, thereby giving it greater combat capabilities."

"Think about it, if a starship ascends to a higher dimension, what happens to the people inside?"

"If we don't adapt to the four-dimensional environment in advance, are we going to wait until war breaks out to cram at the last minute?"

"This..." Fang Xu was speechless for a moment.

You know what, it actually makes some sense.
