Short answer- add lots of water to cement to make it self leveling. Now you will have a new problem- when that much water evaporates the cement will crack because you left out the sand and gravel filler that would normally go into making concrete. All ‘concrete‘ is selfleveling if you are able to vibrate it throughly.
