It's easy to place layers of random materials, overpowering them, and say: Hey you can't break my wall. But i think you're unable to break your own wall, so show me how YOU do it, and i will accept the challange and break it again by a different way.
There is nothing "Ultimate" on this wall. Everyone is able to place a few bars of overpowered materials and call it "Ultimate Wall". Sorry but -1
