These second-hand books aren't worth much, most have changed hands countless times, and some even have different study notes inside.
But the quality of these notes can't always be guaranteed, so you need to rely on your own judgment.
Duke didn't rush to buy this one but continued to browse and found two more copies of the Deep Blue Tide Meditation Technique.
He opened and flipped through them all, choosing the relatively clean one.
One of them was even incomplete, with several pages torn out and missing.
Duke thought to himself that it was a good thing he checked; otherwise, he would have bought an incomplete book.
After paying a low-grade magic stone, he put this second-hand book into his space ring and only took it out to study it after he returned to the dormitory.
Duke planned to self-study the content before class to gain a basic understanding of the Meditation Technique, making it easier when the actual class starts.
