You just find out you are living in virtual world (simulation) and was grant permission to freely create matter. You can create anything, as long as you know it. The admin use you as test subject and see what happen if you have that such ability.

You have 2 ability:

• Inspect the item: the item is near you, in your eyesight, or you can touch the item with your body part (no need eyesight now). Then the item property, material, schema, ... is written in your brain.
• Create a item: create a carbon copy of what you inspect (copy a dollar bill), or you can create new stuff with your creativity (got to start somewhere, scan some basic material like sand, water, ... first then build with basic material)

So, what should you do ?

Others "thing", law of physics, people/biology behaviours as normal.
