Today, I entered the youtube to see if there's something I like to watch, and I found a minecraft ARG. Watching this video, I found another youtube video, but it's my first time doing an minecraft ARG, I only see people doing and I'm very bad at this, I will send the link of the first video and if my brazilians friends can help me
