nanbeiluduo
by hehua
nanbeiluduo is a NeoForge world generation mod that connects generated structures with roads, working from structures already loaded in a world.
What it does
The mod records structure data from chunks that are already loaded, then looks for at least two valid structures and builds roads between them. Roads stop at the outer edge of each structure rather than running into its center, so important blocks inside are left alone. Only structures whose lowest point sits above Y 55 are included, which keeps roads away from mountains and underground structures. Block choice follows the biome, and on ocean floors a road is placed directly on the seabed.
The stored data uses Minecraft's built-in world persistent storage, and the mod keeps track of which structures already belong to the road network. The calculations run on the server side, and the server configuration file is generated after the first start. The environment is server-side only and the mod is released under the Apache License 2.0, but it is not open source. It is published for NeoForge 1.21.1, with the latest file 1.21.1-21.1.216 dated 2026-01-10.
Key features
Automatic road linking
Structures found in loaded chunks are joined by roads once at least two valid structures are known.
Biome-aware blocks
Road blocks change with the biome the road passes through, and roads sink to the seabed when they cross water.
Structure eligibility filter
Only structures with a lowest point above Y 55 join the network, so buried or mountain-set structures are skipped.
Saved network state
Connected structures are tracked in world storage, which adds little to the size of the save file.

Use cases
Who it’s for: Server owners running NeoForge 1.21.1 who want generated structures linked by roads, and players who explore a server world that uses the mod.
How it compares
Structures Plus is published for NeoForge 1.21.1 only, is client and server, and is released under All rights reserved, so it is not open source. nanbeiluduo is server-side only, so players join without it. Villages ReImagined is a server-side only NeoForge mod for 1.21.4 – 1.21.9 under the MIT License, so it targets a later range than this mod. Its license also differs from the Apache License 2.0 used here.

What the author says
This mod automatically detects structures in loaded chunks and records their data. When at least two valid structures are found, the mod generates roads connecting them. To avoid damaging important blocks, generated roads do not extend into the center of structures. Instead, they stop at the outer boundary of each…
