I would take a cannon(capable of  destroying) an army blast.

I would take a helicopter(so i can fly above fights)and get to places as fast as a lightning bolt.

I would take a friend( so i can have some company)so i don’t go mad.

I would take a plasma cannon,so I can destroy any army in one blast, like a bull sprinting while destroying its worried prey.

I would take a notebook, so that whatever i draw comes to life, so when i’m hungry i will draw 5 star luxury food.
