Cataclysmic Era: I can unlock the tech tree

The shadowy structure continued to float slowly ahead of the human fleet.

Judging from appearances alone, the four-dimensional creatures were not harmed at all by the high-intensity saturation bombardment just now.

Inside the Earth Command Center, Lü Yongchang squinted slightly, carefully watching the constantly fluctuating observation data on the holographic projection.

It seems that nothing is unusual.

But he didn't believe that this four-dimensional creature could escape unscathed from such a saturation attack!

Only gravitational weapons can cause damage from lower dimensions to higher dimensions.

Therefore, in the bombing just now, the human fleet used a large number of gravity bombs and black hole bombs.

Undoubtedly, after advancing to the eighth level of civilization, the power of gravity weapons has also increased significantly.

Within their effective range, those gravity bombs can even briefly create terrifying gravity comparable to that of a neutron star's surface!

Needless to say, the black hole bomb, which has undergone several improvements, is not even a simple gravity weapon!

The black hole bomb, which incorporates space technology, can even activate the function of space compression at the moment of explosion—it can pull surrounding objects into the gravitational range of the miniature black hole at a faster speed.

Simply put, compared to previous black hole bombs, today's black hole bombs have a larger effective range and greater destructive power.

The gravity in the affected area has yet to return to normal after such a dense and powerful attack by gravity bombs and black hole bombs.

……

The four-dimensional beings hovered silently in front of the human fleet, not in a hurry to launch a second round of attacks.

Just as Lü Yongchang had predicted.

Even as a four-dimensional being, it paid a considerable price when faced with attacks from powerful and extremely complex gravity weapons.

It subconsciously recalled the terrifying scene from just now.

As it attacked a human starship, several gravity bombs and black hole bombs exploded around it simultaneously!

Several powerful gravitational forces, comparable to those of a neutron star, are simultaneously acting on it from different directions!

That's not even the worst part!

The moment the black hole bomb exploded, a miniature black hole appeared in the universe.

The rapid compression of space indirectly dragged it into the interior of the miniature black hole!

Miniature black holes are still black holes in essence.

As the most extreme celestial body in the universe, even four-dimensional beings would find it difficult to resist the power of a black hole!

Once you fall into the event horizon of a black hole... it will be difficult to get out again!

In the chaos, the four-dimensional creature chose to "sever its arm to escape"!

It resolutely severed a part of its four-dimensional body and threw it into a nearby micro black hole.

After leaving the protection of the core, the part of its four-dimensional body that it abandoned fell into the three-dimensional space through assimilation.

This brought about an extremely large amount of energy and impact.

Under this powerful impact, it successfully broke free from the "gravitational cage" formed by the black hole bomb and the gravity bomb.

Losing part of the body is a minor issue; the real problem is that the core is slightly damaged!

It carefully examined its surroundings.

The core is operating somewhat stiffly, which is a sign of minor damage to the core.

It put away its contempt for human civilization.

Without hesitation, they attacked their own warships, solely to launch a saturation attack on it...

This kind of battlefield execution and decisiveness...

This is enough to consider it a nascent, yet-to-be-developed, civilization of cleaners!

It tries its best to maintain its original form and prevent human civilization from discovering the truth that it is already injured.

Fortunately, human civilization has not mastered the technology of dimensional ascension.

During the stalemate, the four-dimensional being secretly rejoiced.

otherwise……

A strange wave came from ahead, like a slap in the face.

[Ascension, to a higher dimension?!]

[Impossible! This is impossible!!!]

It roared.

At the same time, it hastily activated wide-area tachyon broadcasting.

The intelligence is incorrect!

This is hardly a civilization of cleaners that hasn't even matured yet!

This is clearly the second Cleaners Civilization!!!

……

"Attention all units"

"Entire ship, upgrade to a new dimension!"

Regardless of whether the saturation attack just now caused any damage to the opponent, human civilization now only has one option left.

Revealing the cards! A new dimension!

Isn't it just a four-dimensional being?!

Who isn't a four-dimensional civilization?!

The moment the command was given, the vacuum zero-point furnace, dark matter engine, and antimatter engine simultaneously began operating at full power!

At the same time, the computing power utilization rate of zero also began to soar sharply!

Four-dimensional optical brain array computing center, overclocked!

High-dimensional printing, begin!

Warship upgrade, activated!

hum...

A slight tremor emanated from the bottom of the deck of each starship.

After an extremely brief wait, starting from the bow, the warship, which was originally clearly visible in the three-dimensional universe, turned into a blurry shadow!

The process of creating four-dimensional models is not long.

When the four-dimensional beings discovered the problem and "leaped" towards the human fleet again, the fleet's dimensional ascension was already coming to an end!

……

The four-dimensional being that had successfully jumped to the side of a starship launched another attack, attempting to interrupt its dimensional ascension.

boom!

A dull thud was heard.

Having lost its advantage of higher dimensions, the ship's hull, constructed from a dense quark structure, is clearly not something it can easily break through!

The battlefield situation also reversed dramatically in an instant!

The four-dimensional electromagnetic cannon projectile, carrying a dark matter bomb, swept forward like a storm!

At the same time, four-dimensional spatial rifts also began to be generated rapidly!

Faced with this high-dimensional attack method that was exactly the same as that of the Cleaners civilization, the four-dimensional being breathed a slight sigh of relief.

Compared to three-dimensional space, kinetic weapons are not very effective in four-dimensional space—the extra direction causes a significant drop in the hit rate of kinetic weapons.

For "native" four-dimensional beings, using the fourth direction to evade is like an instinct.

This is why, even if the Cleaners mastered the technology of dimensional ascension, the most effective means of attacking four-dimensional beings are the Quark Fortress and the Black Hole Fortress—as the saying goes, brute force can overcome any technique, and the Quark Fortress and the Black Hole Fortress have enough mass to generate enough gravitational pull and destructive power.

Of course, a neutron fortress can also barely meet this standard.

Just as the four-dimensional being was preparing to evade the attack of human civilization, it suddenly discovered a problem.

Unlike the attacks of the Cleaners civilization.

The accuracy of the attacks launched by the human fleet is terrifying!

"This...how is this possible..."

Before it could figure out the reason, an electromagnetic cannon projectile carrying a dark matter bomb came straight at it!

Swish!

It avoided the bullet at an extremely dangerous angle.

but……

boom!!

The four-dimensional spatial rift came from a tricky angle and hit the spatial shield around it precisely!

Intense ripples immediately spread across the spatial shield!

This is just the beginning, far from the end.

No matter how the four-dimensional beings maneuvered to evade, the human fleet could always lock on and attack in the first instance!

It also tried to fight back.

but……

To its utter surprise, the human starship navigated the four-dimensional space as if it were home, effortlessly using the fourth direction to evade the four-dimensional spatial rifts it emitted.

As it watched the overwhelming, highly precise attacks come from all directions, a sense of powerlessness and resentment welled up in its heart.

Damn it, who exactly is the four-dimensional being?!

P.S.: I've been quite busy today, so I don't have time to write anymore.

I'll finish the other chapter tomorrow...

Damn it, the battle to maintain perfect attendance isn't over yet.
