When you first get into a world you should start digging straight down. Zooming out your screen to max with the magnifying glass. If you touch lava once do not panic. It only kills you if you touch it multiple times. So the red is almost out, you respawn without losing items. Break the lava, marble, granite and obsidian. Click the menu and respawn. Place all your seed on the grey outlines. harvest them in 30 seconds by punching the trees. Click on what you harvested and place. It in the squares and break till you have 200 of each you may need more worlds than 1 that is fine and normal once you have done that place obsidian seeds on the marble to make magic stuff 1.30 minute growth time while it is growing make dirt rows in your world by now you should have a small lock available in the menu in locks place it over the entrance and get out placing blocks on either side of the portal making it your world for 90 days or place the newbie when you start which has a 30 day decay if you do not login. farm until you have 2.500 gems and 2000 blocks be sure to keep some for yourself to keep producing it click on the speech on wifi icon and say something like this "selling magic stuff 999 for a wl also buying spike bomb if you have the wl from selling " hit send costing your 2.500 gems you have trade with someone who buys and buy spike bombs 999 / wl and buy in a trade farm than sell it 500 /wl.
