Having made up his mind, Du You took a few days off and went to a place designated for closed-door cultivation.
Correct, Border City had a special area for mages to conduct closed-door cultivation. Of course, it was only accessible to those who made significant contributions to the city, and wasn't available to just anyone.
"This place is rich in magic elements, but it's of no use to me."
Du You sensed the dense magic elements surrounding him, which were greatly helpful for mages in casting magic and cultivation. However, for a Spellcaster like him, these dense elements were completely ineffective.
Spells rely entirely on the user's magic power, without the need to channel elements from the outside world. Moreover, as a professional, Du You didn't need to cultivate; even if he did, there wouldn't be any visible effects.
