This was a survival world that i made and got to this point in about an hour. I never used a chest, and if you make a map around the spawn point (I never slept in a bed) you might find the nether portal I had, I decided to post this survival world because I didn't really care about it that much, because I didn't put as much effort into it as i did into my main survival world. The dirt house was built by my brother from when we were playing it on lan. I never built a house or a chest, and didn't waste any materials. You can play this survival world and finish what i never finished, if you really want to. The pictures will show you where the nether portal is, from the dirt house. Make sure your render distance is high to find it easily.
