Fredrinn took the pill into his mouth and swallowed it.
To become a Core Formation martial practitioner, one must transform their dantian into a sphere.
During his first year in this world, all Fredrinn did was gather information. After all, he was a person from the modern world so he needed more information about the Great Vemune Continent. He wouldn't have to do this if the previous Fredrinn was good with his studies. Unfortunately, he was an idiot who still had to be beaten up for him to read books. And just like that, he spent most of his time that year reading books.
