He couldn't wait to meet the sorcerers who had created such a marvelous mathematical system and astonishing theories and express his excitement.
Although he only skimmed through the books due to his lack of knowledge, he still sensed the pure beauty of mathematics and the shock of gravity that was beyond its age.
"Mr. Douglas of the Congress of Magic wrote them. The co-authors of 'Basics of Calculus' also include 'Ms. Silvery' and Mr. Fernando of the Congress of Magic," the dealer said with obvious respect when he mentioned them.
