How can I create a fountain of damage text?

Unity Engine

I want to be able to create something like this:

There is text that flys out of the enemy showing how much damage was done. I want to create something like that but I don’t know how to start. What do I do? Im not extremely skilled in GUI. Also, I heard GUI takes 2 draw calls. This is unacceptable because there will be at least 100 GUIs on my screen at once and that means 200 draw calls. Is there some efficient way of doing this? Thanks and I have also searched Google but haven’t found much.

3D text with a rigidbody.
on hit, instantiate a 3dtext prefab, set the text to the damage dealt, add a random upwards force. done
