Cataclysmic Era: I can unlock the tech tree

Combined with the various test data on the side.

It's not hard to draw the conclusion.

An incredibly powerful gravitational force is appearing around the enemy starship!

Gravity manipulation technology!!!

Lu Yongchang's eyes widened as he stared intently at the holographic projection in front of him, trying to analyze the underlying principles from its external appearance.

obviously.

This is impossible.

At least for Lü Yongchang and for human civilization at present, this is nothing short of a fantasy.

Just like...

It's like a primitive man who has just learned to use tools seeing a car speeding along a smooth road.

I don't know where to start, and I can't understand it.

"Zero, let's try to reverse-engineer the gravity around the starship using the gravitational lensing phenomenon!"

Lü Yongchang quickly abandoned visual observation and directly issued the order to zero.

Unlike ordinary tasks, this task involves an extremely large amount of computation.

Even at zero, it still takes a considerable amount of time.

In the star map, a 3D model gradually emerges from scratch.

A strangely shaped "bubble".

"Professor, according to real-time observations, the anomalous gravity is mainly concentrated in this region."

Lu Yongchang didn't speak, but just stared silently at the holographic projection in front of him.

In the projection, the light on the enemy ship's surface became even more dazzling.

suddenly.

It disappeared.

Lü Yongchang's pupils constricted sharply: "Zero, why have the enemy ships disappeared?!"

"Searching..."

"Enemy ship radar signal detected."

"Enemy ship signals are rapidly moving away!"

"Speed ​​Away: 1.1 times the speed of light!"

A string of Chinese characters appeared before Lü Yongchang, constantly shaking his heart.

Thinking back to the huge "bubble-like" gravitational source that had appeared earlier, a thought flashed through Lü Yongchang's mind!

Warp drive!

It's definitely warp drive!

only……

Why would the other party choose to leave out of the blue?

Before he could figure out the problem, the enemy ship reappeared in the holographic projection.

It... went around and came back?

The announcement of zero also belatedly sounded.

"alarm!"

"Enemy ship signal detected approaching!"

Looking at the enormous thing in front of him, Lü Yongchang suddenly had an unbelievable thought.

Is it...

Is the other side flexing its muscles?

"Message detected from the other party's flagship. Receive?"

Lu Yongchang looked at the holographic image in front of him with a strange expression. After a long silence, he gave the order.

"take over."

[With the existence of an unknown technological civilization, you should now realize the technological gap between us.]

To reiterate, hand over 80% of your reserves and all research data, including computer technology, and you may leave safely.

We will leave you enough fuel and supplies to reach the nearest star system.

……

The commander of the Grey fleet looked at the human fleet on the big screen with disdain.

Now, the other side should clearly realize the difference in strength between the two sides, right?

The thought of soon acquiring the other party's amazing computer technology ignited a burning desire in its eyes!

If their fleets had this kind of auxiliary technology...

It even dares to cause trouble for a fully-fledged Level 4 civilization!

Has the other party responded?

It asked casually.

"Not yet..." came a subordinate's report from the side. "No, something's not right!"

"Commander, the enemy fleet's formation is changing!"

"They are not prepared to surrender!"

The little grey commander's face darkened.

Damn bugs!

"Activate Gravity Shield and Magnetic Field Shield."

"Remember, do not attack indiscriminately."

"Their computer technology has great potential for our civilization!"

"...Received!" A hint of worry flashed in the subordinate's eyes, but he still answered.

……

[Unknown technological civilization, we advise you not to test our patience!]

Hand it over immediately...

Lines of information continuously appeared on the holographic projection in the command center.

Zhao Zijie took a deep breath of the deep-sea liquid and subconsciously licked his lips.

My mouth tasted bitter.

"Professor, shall we attack directly?"

Lu Yongchang nodded and sent a message with a cold smile.

"Direct attack!"

"If nothing unexpected happens, the other side should have discovered Zero's existence."

"They want to capture us, and this is our chance!"

"Wait until the other party lowers their guard, then..."

An excited glint flashed in Zhao Zijie's eyes: "Received!"

Finally, we can use this ultimate weapon!

……

Under Zhao Zijie's command, the human fleet's formation slowly changed.

A wide opening gradually appeared in the center of the spherical defensive formation.

Surrounded by a group of smaller starships, the Earth slowly sailed out towards the enemy flagship.

Flagship arrives!

As for the smaller starships surrounding the Earth, they have a unique name.

Dimensional Strike Ship!

The first shot of this counterattack was fired by the Earth!

A beam of dark blue laser shot straight toward the enemy flagship located in front!

Following closely behind were countless electromagnetic cannon projectiles and plasma cannonballs!

Inside the "Earth" ship, Lü Yongchang stared intently at the holographic projection in front of him.

"Gravitational lensing detected!"

A zero-point alert sounded.

At the same time, the straight, dark blue laser, not far from the enemy flagship, drew a graceful arc and bypassed the enemy ship.

Lu Yongchang's heart sank.

Gravity Shield!

Following closely behind were electromagnetic railguns and plasma projectiles.

Unsurprisingly, they were all blocked by the magnetic field shield.

Although he had expected it, seeing this scene still filled him with a sense of despair.

At this point, human weapons could not even touch the enemy's flagship.

As for the original solution...

[Don't waste your efforts on unknown civilizations.]

Another message from the enemy appeared in the holographic projection.

Along with this message, the enemy's encirclement began to shrink continuously, and the enemy flagship slowly advanced under the fire of thousands of [Golden Crow] battleships!

When no one was paying attention.

A tiny [Dimensional Strike Ship] broke away from the group and quickly rushed forward!

After charging for some distance, the cannons at the front of the Dimensional Strike Ship slowly opened.

Under the control of the two-dimensional fragmentation device, a tiny two-dimensional fragment shot out from the muzzle of the cannon!

……

The Grey Fleet also noticed the miniature starship that had broken through the lines at that moment.

"What is this?"

The fleet commander frowned and subconsciously asked the technician beside him.

No response.

It raised its hand and tapped its head.

I remember now, those technicians were ordered to be taken away.

"Destroy it!"

Without much thought, it issued the order directly!
