Currently I am creating a infinite generation game like Minecraft. The code I have written works how I want it too, creating chunks, unloading chunks and storing them. However, If I want to make multiple layers of ground so you can mine underground like in Minecraft, It lags terrible and I have no idea how to optimize this.
How can I optimize my blocks in a procedurally generated world with multiple block layers and only load blocks that the player can see and update the terrain whenever a block is mined to load the new blocks?

local y = 0
local amp = amplitude
local freq = frequency
for i = 1,octaves do
y = y + (math.noise((X*chunk_size+x)/freq, (Z*chunk_size+z)/freq) * amp)
freq = freq*L
amp = amp*gain
end
return y

end
if height/3 > math.clamp(math.noise(x*.02, z*.02), -.5, .5)*20 + 20 then
block:Destroy()
local stone = game.ReplicatedStorage.BlockDatabase.Stone:Clone()
stone.Parent = chunkModel
stone.Position = Vector3.new((chunkX*chunk_size)*size+chunk_size+(x*size), height+y*size, (chunkZ*chunk_size)*size+chunk_size+(z*size))
end
if height/3 > math.clamp(math.noise(x*.02, z*.02), -.5, .5)*30 + 35 then

local stone = game.ReplicatedStorage.BlockDatabase.Snow:Clone()

This is the main script for creating chunks.
