As you climb at a constant IAS, TAS increases.
Yes, it does, but this is related to the change in air density as you climb, not the act of climbing per se and so isn't relevant to the discussion. I didn't mention IAS or TAS in my piece to avoid unnecessary complications to what is just a matter of vector arithmetic.
How does this happen if there is no resultant between Thrust and Drag?
It is nothing to do with "the resultant between thrust and drag"
