One that weighs only a gram, almost impossible to detect, and by the time you do detect it, the strike has arrived. If it can be fired on a large scale, shooting hundreds of millions at once, with such density, let alone 30,000 kilometers, even 3 million kilometers would likely be hard to escape.

And the most terrifying part is, this light needle strike, when aimed at a fixed target, almost always hits 100%.

Because the enemy won’t observe the light needle already on the way, they won’t even know the attack has been launched.

“Commander, this weapon is very good. If operated properly, we could even launch it directly from the solar system towards Proxima Centauri, blowing up those aliens…” Colonel Chu was very satisfied in his heart. It was good that the Pangu civilization was the mother civilization of the Earth civilization. Otherwise, facing this kind of predicament, they might have to wait for death.

In the neighboring star system next door, there are level 3 civilizations. They might also have means to silently destroy a civilization.

“If we launch it from here towards Proxima Centauri, even if it is a light needle, it would take 4 years to get there, right?!” Zhao Yu didn’t understand those data formulas, but he did understand the common units of light speed and light years.

“That’s correct!”

Colonel Chu nodded, “So, the key is how to get the light needle safely to Proxima Centauri. This requires the light needle not to touch any object with mass in these four years, not even one gram…”

“That seems a bit difficult…”

Zhao Yu frowned. Having been cramming knowledge of astronomy these days, he knew that there was a lot of cosmic dust floating in the universe.

Colonel Chu also thought of this, and quickly said, “Commander, do you know what the minimum trigger mass of this light needle is?”

“I don’t know…”

Zhao Yu shook his head. The light needle hadn’t been exchanged yet. They only knew the introduction on the prestige exchange list. As for the specifics, they would have to wait until it was exchanged.

Colonel Chu nodded slightly and gradually calmed down, analyzing, “Most cosmic dust particles range in size from ten to three hundred micrometers, with an average mass of one hundred and fifty micrograms. As long as the minimum trigger mass of the light needle is greater than five hundred micrograms, the difficulty of our interstellar strike will be greatly reduced…”

“That still seems difficult…”

Zhao Yu scratched his head, “Four light years, equivalent to 37 trillion kilometers. Cosmic dust is always moving…”

“If we want to strike across star systems, we need to find a route that allows the light needle to pass smoothly within this light range and calculate the trajectories of these cosmic dust particles…”

“Moreover, it seems we don’t have the ability to detect all the cosmic dust between the solar system and the Proxima Centauri system…”

“It is indeed very difficult…”

Colonel Chu nodded, then added, “But as difficult as it may be, there’s always a chance as long as we find a way to overcome it…”

“Over the years, we’ve received many light signals from the universe. We can judge the position of obstacles based on their trajectories…”

“Every second of light signal can draw a rough map of the cosmic star field. Integrating all the light signals from all time periods should allow us to figure out the trajectories of cosmic dust…”

This is like adding a time dimension to mine sweeping. Every second is changing, and you need to judge the next second based on the situation of the previous second, or judge the previous second based on the next second.

Zhao Yu was surprised, “This is a huge project, with so many light signals received over the years, how many layers of cosmic star field maps need to be built?!”

If each second is a layer of the cosmic star field map, there are 31.53 million seconds in a year. After so many years, the minimum number of cosmic star field maps that need to be built would be in the billions.

And this is just the simplest part of the initial work. The most complex part is finding patterns in these billions of star field maps.

The most terrifying thing is, with the whole world being so big, the amount of light signals received each year is countless. Even if you only calculate the ones that are recorded, it’s still an unimaginable level of calculation.

Chu Daxiao nodded, “With human power, it’s almost impossible to achieve. We have to rely on computers…”

“Commander, there should be a supercomputer at your moon base, right? With its computing power, there might be a chance…”

Uncle Da?

Zhao Yu paused for a moment, then nodded, “I’ll send your idea back and see if it can be calculated…”

“You keep an eye on things here. I’ll go check on when the light needle can be built…”

With that, Zhao Yu returned to his room.

Just then, the system notification rang twice.

[Mihui Civilization (Level 1): 10.0%, Activated 10% nodes, gained 100 Prestige.]

[Sky Bat Civilization (Level 1): 10.0%, Activated 10% nodes, gained 100 Prestige.]

[Prestige: 700]

[Current technology exchange availability: 1]

“Should I save up more and check out other technologies?!”

Zhao Yu was somewhat tempted. The light needle, which cost 500 prestige points, was already so powerful. Would more prestige points unlock even stronger technologies?!

But it was hard to predict. If the next exchangeable technology requires too much prestige, it could delay their preparations.

At present, according to Colonel Chu’s plan, they could only delay for three to five years at most.

If they exchange for the light needle now, calculate the feasible route as soon as possible, and launch an attack on the neighboring star system, the crisis might be completely resolved in four years.

After some hesitation, Zhao Yu finally decided to exchange for the light needle.

[Do you wish to spend 500 prestige points to exchange for the Level 3 Civilization Technology: Light Needle?]

“Yes!”

[Please choose the location for production line installation.]

Whoosh!

After a red light flickered in front of his eyes, the transparent star map of the solar system appeared in his mind again, along with the required installation position.

Zhao Yu was taken aback, his mouth involuntarily agape, a look of shock on his face.

“Does it really require such a big space?!”

What he didn’t expect was that the installation space required for the light needle production line was so large that even the entire base couldn’t accommodate it.

The base he was in now was made from the fragments of Pluto after it shattered, with a diameter reaching 200 kilometers.

The red block indicating the area needed for the light needle production line wasn’t clearly labeled, so Zhao Yu could only roughly estimate that its length exceeded a thousand kilometers based on the length of the base.

This meant that he needed to find a place at least a thousand kilometers long to accommodate the light needle production line.

“This…”

After a thorough search, he couldn’t find enough open space on the moon. He eventually found two places on Earth that could accommodate the installation.

One was the newly planned research area in the Earth renovation project, and the other was the mass food production zone.

“What a coincidence…”

Zhao Yu hadn’t expected that his previous efforts would come in handy today.

Just as he was about to press the installation button in the research area, he suddenly froze.

“I should tell Uncle Da about this, right…”

He was worried that some robots who didn’t know better might destroy the production line.

This thing was a product of Level 3 Civilization technology, exchanged for 500 prestige points. If it was destroyed and couldn’t be fixed, that would be a disaster.

To be on the safe side, Zhao Yu made a video explaining his plan to install the light needle. He wanted Uncle Da to take protective measures to ensure a smooth installation of the light needle production line.

Furthermore, Zhao Yu mentioned his discussion with Colonel Chu about using the light needle to strike at enemies across star systems.

He asked Uncle Da to see if it was possible to create a star map that could illuminate the path from the solar system to the neighboring star system.

After recording the video, Zhao Yu sent this information back to the moon.

Coincidentally, Uncle Da also sent a routine report.

After skimming through it, Zhao Yu found nothing significant but two useful pieces of information.

First, Uncle Da had amassed 500,000 warships and had sent them to the front line in one go, telling him to be ready to receive them.

Secondly, the report mentioned something about the humans on the Bel comet. Uncle Da had spoken with the penguin leaders about designing a reward system.

Moreover, the reward system was working well. Those who were idle and fought all day had all run to the virtual world to learn how to control spaceships.

A new trend had started in human society: whoever could get a spaceship license would have the priority in mating rights. It was a worshipful atmosphere spontaneously generated by the people.

Reading this, Zhao Yu couldn’t help but nod in satisfaction, “At this rate, we’ll soon be able to form a fleet controlled by humans…”

The robot fleet, after all, had inherent risks. They needed an absolutely loyal master control, and couldn’t fight independently at a distance, as there was a risk of desertion.

Therefore, it was necessary to form a fleet controlled by natural persons. Even if, according to the current situation, this fleet might not be used, it was important to have it..
