If you lived in a cyberspace world, what augmentation would you make first?

yyy: Iron Concrete Member

Zzzz: You are a fool. The concrete from friction crumbles, and is also toxic. You don’t get fucked. Well, or you will stay at the end with an armor in diameter in a centimeter and an angry girl, forging a concrete crumb from the secluded places and hiding you with an 18-story mat. I recommend titanium.
