Cataclysmic Era: I can unlock the tech tree

The jagged flashes of light from the explosions continued to illuminate the scene.

In the tachyon radar, the distance between the enemy fleet and the human fleet is constantly decreasing, while the enemy ships' speed continues to increase.

10c, 20c...

Upon seeing the predicted course that ultimately pointed towards their own fleet, Bai Yixuan's expression instantly changed.

"Offense and defense have shifted!"

He managed to squeeze out a few words.

The next moment, he instinctively gave the order: "All warships, enter warp drive..."

"No!" Zhao Zijie's voice rang out abruptly, interrupting his order, "Continue launching warp missiles!"

"To delay the enemy's approach or prevent them from aiming their space weapons at us, we must continuously launch warp missiles."

"But this way..." Bai Yixuan's face was extremely grim, "This way, the human fleet will be unable to enter warp drive mode!"

"Wouldn't we just become sitting ducks then?!"

"Their warships aren't as fast as ours. Once we enter warp drive mode, we can easily employ guerrilla tactics against them."

Zhao Zijie said in a low voice, "Can your speed compare to a spatial rift?"

silence.

Yes, the human warship's top cruising speed reached 100c, which was twice the speed of the Enroget warship.

But the speed of a spatial rift is 800c!

Without warp missiles to harass them, can the human fleet really withstand such an unknown attack?!

Within seconds, a thin layer of cold sweat seeped out on Bai Yixuan's back.

"...Were we checked?"

He swallowed hard, looking at the holographic projection in front of him with some confusion.

At first glance, the human fleet seemed to be facing only one dead end.

Suddenly, he jolted awake, the confusion in his eyes vanished instantly, and his voice became urgent: "No, that's not right!"

"There's a problem!"

"If the Enroget civilization could really achieve this..."

"Then they wouldn't have needed to hide in the star system in the first place!"

"Why didn't you just wipe us out with your flagship?! Why wait until now?!"

"so……"

A glint of light flashed in Zhao Zijie's eyes, who was far away in the Kepler 452 galaxy, as he and Bai Yixuan, hundreds of light-years away, spoke in unison:

"The Enrogett flagship definitely has shortcomings we hadn't noticed before!!"

……

Inside the Kepler 452 command center.

Zhao Zijie stared intently at the holographic image in front of him.

The screen is playing footage of all the images and videos released after the Enrogett flagship appeared, looping at accelerated speed.

From curvature and speed to hull structure, he is trying to find the "shortcomings" he had previously overlooked from various angles.

He wasn't the only one trying this; all the military commanders in the command center were doing it.

As for Lü Yongchang and the other researchers, they were writing and drawing various symbols and formulas on the holographic projection.

They are looking for solutions to the spatial fissures.

Time passed second by second.

The Enroget fleet successfully crossed half the distance.

At this point, the two fleets were only 0.05 light-years apart.

The atmosphere became tense and anxious, both in the command center and the expeditionary fleet.

……

suddenly.

Zhao Zijie slowly widened his eyes, as if he had discovered something.

He spoke somewhat urgently, "Zero, establish a spatial coordinate system with the Enrogett flagship as the origin, and mark the locations of all intercepted warp missiles on it!"

The moment the words were spoken, the holographic coordinate system appeared instantly.

Dense, tiny, jagged red lines appeared rapidly in the azure holographic coordinate system.

Zhao Zijie reached out and dragged the image, shrinking the screen.

A spherical structure made of jagged red lines suddenly appeared before his eyes.

"really……"

Zhao Zijie's previously somewhat weary eyes suddenly lit up: "Space weapons have a very limited range!"

"If the statistics are correct, the enemy's weapon range should be around 750-800 light-minutes!"

He couldn't help but laugh: "Too short!"

"With such a short attack range, no wonder they had to stay hidden in the star system before!"

"Commander Bai, did you hear that?" Zhao Zijie smiled and turned to look at Bai Yixuan in the holographic projection. "You should know what to do, right?"

Bai Yixuan, staring at his dark circles, let out a long sigh of relief: "Don't worry."

"Guerrilla warfare, that's our old specialty."

……

front.

Under Bai Yixuan's orders, most of the supplies and personnel inside [Chi You] were quickly transferred to other warships.

no way.

[Chi You] is too clumsy.

Its maximum cruising speed is only 20c, which is slower than the cruising speed of the Enroget fleet, making it impossible to use for guerrilla warfare.

But as the most powerful war machine in the history of human civilization, even as a sacrifice, it still has its unique value—to cover the rear.

It can relentlessly exert continuous firepower to suppress the Enroget civilization.

Incidentally, let the human fleet "experience" the damage of spatial rifts.

Warp drive activated.

After replenishing all supplies, the human expeditionary fleet vanished instantly into the visible universe.

Here, only the [Chi You] planetary fortress, fully loaded with various high-powered weapons, remains.

Under Zero's control, the missile silos on the ground continuously spewed out deadly flames.

The electromagnetic railgun and antimatter gun were already preheated and ready to unleash their most intense barrage once the enemy ships reached their designated positions!

……

this moment,

The Enroget civilization once again witnessed the full power of [Chi You], who bore the name of the master of war.

Gravity bombs, black hole missiles, warp drive missiles, electromagnetic railguns, antimatter cannons...

Warp drive weapons and conventional weapons complemented each other, unleashing a final roar at the enemy!

Faced with this imposing attack, the Enroget fleet did not withdraw from warp drive and maintained a speed of 50c.

They made only a slight adjustment to their course—the fleet would pass right by the bulky planetary warship.

The closest distance between the two is exactly 800 light-minutes.

A few minutes later.

The final alarm sounded in the tachyon radar.

800 optical splitting warning line.

Suddenly, a strong spatial-temporal fluctuation appeared.

The spatial rift, traveling at a speed of 800c, flew directly toward Chi You, who was spewing out firepower at full force in the invisible faster-than-light universe.

One minute later.

hum!

The planetary-class combined shield appeared to have been severely damaged.

The shield generation device emitted a bright light instantly and then overloaded and crashed in an instant!

The azure shield held out for less than 0.1 seconds.

Swish!

The jagged cracks appeared precisely in the equatorial region of [Chi You].

Penetrating wound!

The 6500-kilometer-diameter Chi You was pierced straight through by this spatial rift!

boom!!!

An explosion erupted from the inside out, and powerful radiation surged outwards like a tidal wave.

[Chi You] crashed!

Its conventional weapon, fired at the last moment, still "slowly" travels at a speed less than or equal to the speed of light.

But the Enrogete fleet swept past the exploding planetary fortress at a speed of 50c.

The difference between a Level 5 civilization and a Level 6 civilization is evident.

Even if the opponent only possesses a weapon from a level six civilization.

Boss, you're awesome! (voice cracks)
