Magic: My Magic Can Mutate and Evolve

Smith was accidentally reincarnated into a world of swords and magic. He became the descendant of a noble family.
According to Smith’s logic, something was off with the plot which he was experiencing.
His father was very kind and was respected by all his siblings. This was not at all the plot which would be experienced by a main character.
Usually, wouldn’t the plot be something along the lines like him being neglected by his father and disdained by his siblings?
At this moment, Smith awakened the cheat codes that would allow his magic to mutate.
Any magic skills learned by Smith would automatically evolve and become the best magic.
[Your water ball technique has scanned your memory. It was deeply fascinated by the water escape technique and the water dragonball technique. Shocked by its own limitations, your water ball technique has trained hard and finally achieved mutation.] From then on, his water ball technique became the water dragon technique.
[Your flying magic has scanned your memory. It was deeply fascinated by the ability of the flight devil fruits. Shocked by its own limitations, your flying magic has trained hard and finally achieved mutation.] From then on, Smith did not have to spend any magic power to use his flying magic. His flying magic also became the strongest flying magic in this world.
Smith, “I’m really an ordinary magic user. I’m not the God of Law!”
