DeepUnderWorld

1.A new dimension, the Underworld, has been added.

2.The original vanilla Nether Portal has been disabled.

3.Players need to build a portal with obsidian blocks on the bedrock in the Overworld to travel to the Underworld.

4.After digging down through two layers of bedrock in the Underworld, you must build a Nether Portal out of obsidian on the Mantle Block to get to the Nether.

5.Added a portal to the Overworld spawn point (can only be activated in the Overworld).

6.Added random teleportation portals: place four different rune stones on the four corners of the activated portal.

7.Shulker Shell is added to diamond equipment crafting recipes, and also available as loot from monster spawner chests in the Underworld.

Note: Random teleport portals must be at least 5 blocks away from other portals, otherwise update‑related issues may occur.

Configurable: ore generation, mob generation, spawner and chest loot in Underworld dimension.

1.添加了一个新维度：地下世界。

2.禁用了原版下界传送门。

3.玩家需要在主世界的基岩上，用黑曜石搭建传送门，前往地下世界。

4.在地下世界向下挖穿两层基岩后，需要在地幔方块上使用黑曜石搭建下界传送门，方可前往下界。

5.增加了主世界出生点传送门（只能在主世界激活）。

6.增加了随机传送门，需将四个不同的符文石放置在激活的传送门四角。

7.钻石装备的合成配方加入潜影贝壳；地下世界刷怪笼的箱子战利品也包含潜影贝壳。

注意：随机传送门距离其他传送门至少5格，否则会出现更新失效问题。
