Is it possible to raycast from a vector3 point to another vector3?

Let's say I want to RayCast from a character to another character. I know you have to put a direction in the second parameter but is there some way I can do it where it goes directly to a vector3 point?

Example of what I want but what is not possible:

local V1 = Vector3.new(0,0,5)
local V2 = Vector3.new(5,2,6)
workspace:Raycast(V1, V2) -- So it goes from V1 to V2
