Built this myself in 7 days. Took 54 hours. Not proud of how no life i went on building this, but its a cool build. You can find it at x:513 z:-4156. In the nether the closest portal is at x:58 z:-508 theres a cobble stone slab path to it. You'll need to max your render distance to see it from the viewing platform
I think it's fast enough. Faster than handplacing and also you can do other stuff/afk while it builds
https://www.youtube.com/watch?v=w1Cfgm62aEw watching this video i genuinely think i am faster. I do agree that its way easier and better tho, but the building part wasnt even the most frustrating part of the playthrough, the most frustrating part was searching for 4 hours looking for a coral reef
