After leaving this research facility, Saine and the others continued toward the Steel Ruins.
They had now reached the central region of the Steel Ruins. Further in lay the true core of this subspace secret realm.
Wall-E had not come to this area often over the past ten million years.
In its words, "There's more than enough garbage-cleaning work around the outskirts of the Steel Ruins, so under normal circumstances, I don't come here."
Under what circumstances would it come?
Only when Wall-E's body parts suffered obvious damage would it come here to search for replacement materials.

What ordinary robot could withstand the erosion of tens of millions of years? And what garbage-cleaning robot could endure a strike from an Eight-Winged Angel?
