The title is kinda self-explanatory; however, easier said than done. So lemme get it started. Building a nuke-proof base may sound easy to most of you, many of you might simply say "Just get a forcefield or 3 layers of reinforced stones/glasses". But I want to give everyone a little bit of challenge, and here's what I want for the nuke-proof base: 1. No force fields used. 2. No bedrocks used. 3. Can stand against TNT explosions and Nuclear explosions completely unscratched. 4. Can protect every single items inside the base. (That means dark/red matters won't work, as explosions go through it even they will not be destroyed.) 5. Must not take up too much spaces. These are the rules I have for the nuke-proof base. I am asking everyone this is just for my tekkit researches and curiousity, seeing if it's possible to make a base completely invulnerable from no matter how many nukes explosions simultaneously.
