How to go to hell for my world mobile phone version, my world mobile phone hell raiders.

In my world mobile version, if players want to go to hell, they need to make a 5*4 door with obsidian, and then use flint, and the purple hell door will appear. At this time, players only need to stand in the purple aperture and it will be automatically transported to hell, but hell is very dangerous, and a series of protective work must be done before entering. Among them, the method of obsidian is to pour water with magma, or to wash magma naturally with water flow, while flint can be synthesized from flint and iron ingot.
