《我的世界》中一次性放一排方块的指令是什么（我的世界一口气放很多方块的指令）

你是说1秒1秒的叠放吗，我知道

/summon FallingSand ~ ~1 ~ {Tile:152,Time:10,Riding:{id:"FallingSand",Tile:137,Time:10,TileEntityData:{Command:"fill ~ ~-7 ~1 ~ ~-1 ~1 redstone_block"},Riding:{id:"FallingSand",Tile:137,Time:10,TileEntityData:{Command:"say 1"},Riding:{id:"FallingSand",Tile:137,Time:10,TileEntityData:{Command:"say 2"},Riding:{id:"FallingSand",Tile:137,Time:10,TileEntityData:{Command:"say 3"},Riding:{id:"FallingSand",Tile:137,Time:10,TileEntityData:{Command:"say 4"},Riding:{id:"FallingSand",Tile:137,Time:10,TileEntityData:{Command:"say 5"},Riding:{id:"FallingSand",Tile:137,Time:10,TileEntityData:{Command:"say 6"},Riding:{id:"FallingSand",Tile:137,Time:10,TileEntityData:{Command:"setblock ~ ~-1 ~1 redstone_block"},Riding:{id:"FallingSand",Tile:137,Time:10,TileEntityData:{Command:"fill ~ ~ ~ ~ ~9 ~1 air"}}}}}}}}}}} ?
