"Unfortunately, we got too little Shadow Copper. From one ton of Shadow Copper Rough, we can only extract ten grams of usable material."

"This is just one milligram of shadow copper. After I break it down, it can be used about ten times in a small space."

Xia Chujian felt secretly sorry.

She couldn't ask for something that couldn't be mass-produced.

But she blinked and suddenly said, "Even the air can't penetrate?! Will we suffocate from lack of oxygen?"

Su Buyan knocked her head in annoyance, "How could I not have thought of this? I have placed a small oxygen concentrator here, which can at least support our breathing for 24 hours."

Xia Chujian said "Oh" and said with a smile: "No wonder I didn't feel anything was wrong after I came in."

Su Buyan coughed lightly and said, "Stop talking nonsense. My time is limited. I can only stay here for three hours at most. Let me ask you first, you flew over the Sester asteroid belt for twelve hours. Were you teleported through a small wormhole?"

Xia Chujian also coughed and said, "Master, you may not believe this, but I really don't know how I flew over that asteroid belt in just twelve hours."

Su Buyan said nonchalantly, "That's right! During the process of generating a small wormhole, without special equipment, you wouldn't even notice that you were being transported through it."

Xia Chujian: "...Okay, since you said so, I believe it."

Then she stroked her red spider lily necklace and asked, "By the way, Master, have you stored the star map of the asteroid belt in the mechanical intelligence of Shao Siming's black silver mecha?"

Su Buyan frowned. "A star map of the Sester asteroid belt? That thing doesn't even exist. Where can I store it?"

Xia Chujian: “!!!”

No way?!

That star map actually has nothing to do with Master's Shao Siming Black Silver Mecha?!

This overturned many of her previous assumptions.

Xia Chujian also frowned and said, "Really?"

"Really? Why are you asking?"

Xia Chujian thought for a moment and said, "Master, this is what happened. After entering the asteroid belt, in order to stay in touch with my three roommates' fighter planes, I used nano-scale fiber optic data cables to connect the four fighter planes..."

Before she could finish, Su Buyan immediately said, "Oh right! Huo Shuai said you have some amazing nano-level fiber optic data cables! Show me! I heard they can even cut through star rock fragments?!"

Xia Chujian had no choice but to stop talking, turn on the fighter's control system, and transmit the nano-level fiber optic data cable stored in the groove at the bottom of the fighter.

In order to transmit to the interior of the cabin, Su Buyan had to stop his gray light shield for a second.

Only after the fiber optic data cable was transmitted in did Su Buyan unfold the gray light shield again.

In that cabin, Su Buyan took out his own instruments and began to test the physical data and performance of the nano-level optical fiber data line.

Fifteen minutes later, Su Buyan's brows furrowed even more tightly.

"...That's it? It can even cut through the asteroid rock fragments in the asteroid belt?!"

Xia Chujian silently added, "Maybe they even cut off an Aurora-class fighter..."

But there is no need to tell Su Buyan.

The next second, Su Buyan took out an ordinary piece of iron and cut it with the fiber optic data cable.

No matter how he used it, he wore out the fiber optic data cable, but he couldn't damage the iron block at all.

Xia Chujian's face gradually turned pale, and she even covered her mouth.

Su Buyan raised his eyelids and looked at her: "Tell me the truth, did you really use this fiber optic data cable to connect four fighter jets in the asteroid belt? And even cut the asteroid rock fragments?"

Xia Chujian nodded heavily. "Master, it's absolutely true. I saw it with my own eyes. And my roommate and I relied on this to ensure that we didn't lose contact with each other in the asteroid belt! Our four fighters flew out of that asteroid belt at the same time. If you don't believe me, you can check the surveillance at the Zangge Star Interstellar Terminal!"

Su Buyan tilted his head and thought for a moment, then said, "The iron block I have here is the most common kind. It can't be cut without any special metals or exotic metals added to it... If you're not lying, then maybe there's something I haven't analyzed yet..."

Xia Chujian was also confused at this moment.

She stroked the piece of iron with her hand in disappointment, and it indeed had the texture of an ordinary piece of iron.

And Su Buyan used it for experiments, so there must be no problem with the material.

So the nano-fiber optic data cables that were once indestructible in the asteroid belt are not actually that powerful?

Then how did it cut off those star rock fragments and the Aurora-class star fighter?

Just when Xia Chujian was puzzled, Su Buyan was already looking at the nano-scale optical fiber data cable that was broken into strips, speechless.

He thought this thing was very powerful, but when he tried it with his own cutting tools, he directly cut through the fiber optic data cables.
