So..... when 1.9 released the villagers, everyone expected them to do something. Well.... they do do something. I have a theory that the villagers are actually incredibly advanced people. And they have invented guns, lasers, rockets, they are currently working on the invention of the atomic bomb. Ya see, in every village there is a well... my theory is that if you go to the bottom of the well and mine..

36 blocks to the right + 16 blocks down, then mine how ever many villagers in that village to the left, and then 18 blocks directly up, you will find a cave. If you get to the end, there is a monster spawner, breaking it reveals a chest held by iron bars and two Slimes, in the chest is a book, bringing the book to any of the villagers makes him give you a button. Placing the button next to the door of any of the houses opens of a gigantic hole hidden by holographic blocks. At the bottom of the hole is a red portal made of diamond ore, glowstone, and end stone. Going through it takes you to a secret room where you can learn about the technologically advanced lifestyle of the villagers.

They have probably invented jets, snowmobiles, tanks, blimps, and things beyond our wildest imagination.

Oh yeah i forgot to mention, you have to have legit beaten the enderdragon on a hardcore mode, and you have to do this on that world. Also, you have to beat the enderdragon using only a wooden sword, 12 arrows, a bow, and a leather helmet.

Well.... go ahead... try it, see if i'm right.
