Cataclysmic Era: I can unlock the tech tree

Compared to the universe, the area currently covered by the self-splitting probe is very small.

The ambitious cosmic listening project has only just begun to sprout.

Therefore, Lü Yongchang had no idea that the universe had fallen into chaos, let alone that the source of this chaos was human civilization!

At this moment, all his thoughts were focused on the two dimensional creatures he had just captured.

The Chinese Academy of Sciences has basically completed its research on four-dimensional space and is preparing to gradually shift its focus to one-dimensional and two-dimensional space.

At that moment, one-dimensional and two-dimensional beings "fell from the sky".

Upon seeing the arrest plan successfully implemented, Lü Yongchang was overjoyed.

Facts aside.

Pastoral style...

What a kind person!

With the experience gained from four-dimensional research, coupled with the "selfless dedication" of [Silk] and [Ant], the Academy of Sciences' research on one-dimensional and two-dimensional structures has progressed extremely smoothly.

Just like the civilization of cleaners.

With a complete grasp of four-dimensional technology, the analysis of two-dimensional data only took a few thousand years.

As for human civilization...

With the help of Lü Yongchang and Ling, this time was shortened by several hundred times.

……

Ten years later.

Boötes is empty.

After ten years of high-speed travel, the human fleet finally stepped into this desolate star field.

Although they had expected it, every academician and crew member still felt a sense of unease the moment the fleet entered the Boötes Void.

While navigating between superclusters, the human fleet would occasionally encounter galaxies of varying sizes.

These are like scattered oases in the desert, always bringing a glimmer of hope to travelers on their journeys.

But everything changed after entering the Boötes Void.

Looking around, there are almost no galaxies.

This means that human civilization will be unable to receive external supplies for a very long time!

Human civilization has now mastered vacuum zero-point energy. Strictly speaking, our dependence on external resources is not high. In fact, under certain extreme circumstances, humanity can continue its civilization without relying on external resources!

However, the pace of technological development is too fast, and people's ingrained ways of thinking have not changed.

Subconsciously, the lack of external supplies means annihilation.

Even though they knew the fleet didn't have a shortage of supplies, the crew members still felt extremely tormented watching the supplies in their small universe dwindle.

This situation lasted for less than a year before disappearing completely.

It wasn't that the crew members adapted to this feeling, nor that they changed their perceptions; rather, something worse happened.

After nearly ten years of rest, the tachyon radar once again sounded an alarm that sounded like a death knell.

Inside the command center of the Earth.

Looking at the signal source located at the front of the fleet, everyone's expression became serious.

Looking at the observation data in the holographic projection, everyone had their own answer.

Four-dimensional beings!

Only four-dimensional beings could possibly have such a high speed of travel.

Only four-dimensional beings could accurately locate human civilizations that have changed their course several times!

"Attention all units, prepare for combat!"

"Warp coordinates have been sent to the starship's mainframe. Warp immediately!"

……

Inside the Hollow of Boötes.

Perhaps sensing something, the shadow did not make any move after emerging from the wormhole, but simply waited quietly in place.

A few seconds later.

A strong spatial fluctuation came, and the space in front of us quickly distorted, with starships emerging one by one.

Although the four-dimensional leap has not yet ended, the dark light of the dark matter cannon has already begun to flicker.

[Four-dimensional leap...]

It muttered to itself, "They've already mastered some four-dimensional technology; no wonder silk and ants are no match for them!"

But... isn't using four-dimensional jump in front of me a bit too confident?

Before the words were even finished, the shadow had already vanished from the spot.

Almost simultaneously, the shadow had traveled over ten light-years to reach a starship.

In an instant, the gray shadow surged and crashed straight into the starship.

No collision occurred.

It was as if a phantom projection had passed through the starship.

but……

All the crew members inside the starship are dead!

Cause of death – organ rupture!

For four-dimensional beings, bypassing the armor of a three-dimensional starship and attacking its interior directly is an incredibly easy task!

It did not linger and continued to disappear into the visible universe.

Perhaps feeling that this method of attack was too inefficient, it changed its target to the Zero Point Furnace.

A shadow appeared on the side of another warship and swept across it quickly.

boom!

The flash of the explosion had barely appeared when the shadow vanished again!

A continuous four-dimensional leap!

The four-dimensional jump that human fleets need to use to consume a lot of energy is just a very common means of getting around for four-dimensional beings!

The pure vacuum zero point can surge within the body of a four-dimensional being, providing a continuous source of energy for its every movement.

The shadows flickered rapidly within humanity's first fleet, each flicker easily claiming the life of a starship!

The scene that unfolded on the main battlefield far exceeded the expectations of Lü Yongchang and the other academicians!

Both are dimensional beings and both are level eight civilizations, but the combat power of four-dimensional beings is not on the same level as that of low-dimensional beings!

……

The sudden shift in the battlefield situation did not affect the command center.

On one side, Lü Yongchang and the academicians were fulfilling their duties, analyzing the attack methods of four-dimensional beings through a large amount of data in order to find solutions.

"Decoy attack!"

A ruthless glint flashed in Zhao Zijie's eyes, and he gave the order in a deep voice!

……

Judging from the current battle situation, if the four-dimensional beings want to cause damage to human starships, they will inevitably have to get closer to them or make contact.

Although four-dimensional beings possess extremely high mobility due to their four-dimensional jump, this also gives the human fleet an opportunity!

Using its own fleet as bait, it launched a high-intensity saturation attack on the enemy!

On the battlefield, the shadow disappeared again and reappeared beside several Golden Crow battleships.

Not far away, the dark matter cannon and the spatial rift finally completed their charging.

A flash of dark light and a black spatial rift rushed past, hurtling towards the shadows!

Gravity bombs, massive black hole bombs...

Pulled by the Star Picker, a pair of positive and negative stars hurtled towards the target area at faster-than-light warp drive!

Annihilation Starburst!

The main strategy is saturation attack!

boom!!!

The explosion illuminated the dark starry sky and also engulfed the human starships!

Under the chaotic gravitational pull, the flames from the explosion formed dazzling patterns.

Countless miniature black holes were frantically devouring the matter and energy produced by the explosion!

The flames and the miniature black hole gradually dissipated, and the scene inside the target area gradually became clearer.

Shadows still lingered slowly in the aftershocks of the explosion.

Completely unharmed!

P.S.: Thanks to Zhenxun for the expert certification!

Thank you so much! You're awesome!
