A magical world, the Nether!
I remembered I had some obsidian. I got iron and and gravel. I used the trick until I got flint. I made a flint and steel. I made the formation for the portal and lit it. It looked like a radiated purple light that shon over me. That’s it, I jumped in. Then I saw it. The depths of the underworld (the underworld is were I came from). Ghasts, pigman, magma cubes and blazes. Then everything stoped and  I thought “I’m not ready.” I went back to the underworld. I got a lot of materials. But still not enough.
