Ever since Ves received the Mech Designer System, he became astounded by how much it was capable of. It could materialize objects out of nothing, integrate a lot of knowledge in his mind, transport his consciousness back into the past and more.
Yet one question always haunted him in the back of his mind.
Where did the System obtain all of the resources and energy to accomplish these reality-bending feats?
Someone as paranoid as Ves never took the System for granted. The more wonders it showed off, the more suspicious he became at the price he needed to pay.
"Nothing comes for free. Not even the System is exempt from this rule."
Now, the truth came out.
Whether the System had always intended to end its so-called 'introductory period' once one of his designs earned him 1,000,000 DP or not, Ves would have exhausted its generosity at some point or another.
