The Overworld – Chaos

Welcome to the world-chaos.
First of all, this is a map with datapacks as the core.
You can understand it as a collection of superflat or world with other single biome.
Different from the vanilla overworld, the game content given by this map is equivalent to the skyblock.
The players spawn point remains the same, so dont throw lava there anymore.
Well, at the beginning of the game, you will have an oak_sapling and a dirt. Just want to get rich, first tree.
Then you can find the ruined portal somewhere(will add command for player), where the obsidian,magma,netherrack and lava found will affect the advance of island.
Then, you should think of a Stone spawner. But it needs lava and water, so how can water be obtained?
In fact, the temperature of this formation is defined as 0.2. Therefore, it will snow here, and when it snows, you may want the snow block.
Place a pressure plate on the snow block (all types are available), then stand on it and wait for 4 seconds, the snow block will turn into water.
The colors of water and grass block are not general blue and green, but I think it will be more realistic.

Don’t go to the nether, just because it’s not done yet. If it does, I am not sure whether the game will have problems after the nether is updated.

Features exist：

Hostile creatures in the overworld will arrive as expected.（Hisk，cave_spider,pillage........）

The passive creatures of the overworld will gather here.(panda,Pufferfis,dolphin,fox,axolotl......except goat and turtle)
Snow block under Pressure plate below player will transform into water in 4 sec.
Temporarily, only the ruined portal structure exist.

Place a composter  on the dirt,grass block and all seeds and its variants, and then compost. Do not take out the bone meal, and wait for the magic to happen!(rate: 0.5)
HP: You start with 3 hearts. Get more hearts when higher level(xp) .
the netherrite mobs can spawn in the nether, and the nether is also like a skyblock.
