This mod is designed as a lightweight, performance-friendly utility for NeoForge 1.21.1. It addresses the need for efficient mining, by allowing players to harvest entire veins of blocks with a single action.

Key Features

Crouch-to-Activate: To prevent accidental destruction of your base or unwanted terrain, the vein mining logic only triggers when the player is sneaking (holding Shift) while breaking a block.
Universal Compatibility: Unlike some mods that only work on ores, this "Universal" version is designed to work with any ore, provided you are using the correct tool.
Tool Durability Safety: The mod intelligently monitors your equipment. It will automatically stop the vein mining process if your tool's durability reaches its limit, preventing your high-tier pickaxes from accidentally breaking.
Full Drop & XP Support: It uses native NeoForge hooks to ensure that all blocks drop their appropriate items and Experience (XP), fully respecting enchantments like Fortune or Silk Touch.
Smart Mining Logic: The mod uses a 3x3x3 "neighbor check" to find connected blocks, ensuring it captures diagonal veins and irregular ore clusters.

Why Use This Mod?

It serves as a clean alternative to heavier mods like FTB Ultimine. By focusing on core functionality and using optimized code to prevent infinite loops (through a "safety flag"), it maintains high server performance even when mining large veins.
