Notes:

• The generated schematic is 2 blocks wider than the actual digging range. If you want a 17x17 chunk perimeter, you must input 274x274 instead of 272x272.

Side-Trenchless Smooth Side-Sweep World Eater（STSSWE）

Description

• This design incorporates the advantages of a super-harvest architecture trencher without the need for side trenches. Furthermore, it is more cost-effective and easier to run and maintain.
• More suitable for the Overworld, as water is used for explosion protection.
• The interior also includes a convenient device for placing waterlogged stairs while AFK.
• The design is snow-proof but not ice-proof. Also note that amethyst growth can break the water wall, and sculk sensors outside the water wall may activate the pistons that push the stairs downward.

Duper:

• The TNT will not destroy blocks outside the water wall, even those with zero blast resistance, and this device will not break due to TNT random momentum either.
• However, there is a small chance that it will not completely clear the blocks under the stairs. If that happens, simply clear them manually and reset the drainer.

Usage Instructions:

• Border descent shaft: The area marked by the moss blocks is the descent shaft range (including the moss blocks themselves, totaling 13 blocks wide). It is recommended to use a side-trenchless trenching machine to open the shaft.
• Stair placement: After construction is complete, stand inside a cauldron, face the sign, and close the trapdoor. While holding stairs, right-click on the lower half of the side of the cauldron. Continue until the opposite side is blocked, then remove the blocking piston and place the remaining stairs at the end.
• Start/Stop: Right-click the note block to start; click it again to stop. The redstone lamp acts as a status indicator, so you can easily tell whether it's running or not.
