Lu Zhou had only ever received two pieces of debris before.
The first debris was a battery, some kind of lithium battery. Lu Zhou used the scanner gun to verify that it was indeed a lithium battery.
The only thing he wasn't sure was exactly what the battery should be used for.
As for the second debris, it had the shape of a cube. However, Lu Zhou had no idea what it was.
Not just that, he wasn't even sure what was "broken" about the debris.
After all, that big cubed-like thing didn't look like it had anything missing. There wasn't any noticeable damage on the surface either.
As for this third debris, it actually looked like a real "debris".
The side of the meter-long cylindrical object looked like it was hit by something that left a big gap behind.
