It should be warned that it is dangerous to dig at such a height directly above oneself - it is fraught with sudden soil collapse, if not ignited from magma flows. There it is necessary to expand the network of caves until a lake of lava appears.
The easiest way to do this is to descend to the height of the sixteenth block, digging deep into the ground. First, it is made from a bucket, then water is drawn into it from the nearest lake, and now, before proceeding directly to how to build a portal to hell, it is necessary to find lava. The simplest of them consists of three stages. Minecraft boasts several methods of acquiring this rare material. Obsidian must be obtained in any case, because without it there is no way how to build a portal to hell. It is a very rare ore, characterized by increased strength, which is formed from the confluence of water and lava.
The first challenge faced by the inhabitants of the cubic world is the extraction of obsidian. It is very easy to get most of the materials needed to erect a building - they either lie on the ground or are mined deep in mines, while building a portal to hell is no longer so easy. Many players, having explored the lands lying on the surface in the world of Minecraft, sooner or later stop in their favorite place and begin to rebuild their unique home.
