It's not that the college lacks knowledge reserves, but with the access Link currently holds, the "public" knowledge and information he can reach are only this much.
Even if Link is not lacking in "academic points" now, he cannot find more resources and literature he wants.
Link had two options:
The first was to go hunting for them in the city of Ravensmouth, especially in the black market, where he could always find something;
The second was to ask for help from Serene Wizard and (or) Sage Palo.
They could definitely provide some real, high-level documents that Link could not find now no matter how hard he looked.
After all, Ravensmouth College still has a unique headquarters.
Only wizards above level two can enter.
After some consideration, Link made his decision.
Having too many lice does not itch.
Anyway, he was already tightly bundled with Sage Palo's family, so why not tie it a little tighter?
Being a ride-along on the big leagues, was not bad.
