So if were a bad guy organization / nation. I’d spend billions of dollars on a super secret tunnel making machine.

I’d use lasers to liquify the rock

I’d build tunnels all over the enemy

I could then infiltrate at will whenever wherever

I wouldn’t spend it on space, jets, or any other bull shit.

Nope they’d never even realize I Could I’d tunnel under their gold reserves until it was too late.

If I were the bad guys
