Straight!

The clouds covered the sky. As it was night, they glowed beautifully as moonlight cascaded down the air. The beautiful moonlight passed through the windows and poured into a room with many bookshelves, a firehouse, multiple sofas, and tables. It spread outwards, appearing no different from twinkling light streams that illuminated the entire place. It adorned the black hair of a person who was rummaging through the bookshelves in blinding silver.

"Start by memorizing all of these books." Pill Emperor said after placing dozens of books on the table next to Elliot.

Then, he turned to leave.

"Teacher, where should I look for you after memorizing them?" Elliot asked formally.

Pill Emperor took out a piece of paper, ripped it in two halves, and threw it to Elliot.

"The paper will guide you to me." After throwing these words at his new student, Pill Emperor opened the door, stepped out of the study, and closed it.
