My skill tree increases every day.

Every morning, Lin Yuan would wake up to find one item missing, along with a new, unfamiliar memory. The first day, it was a set of old books, and he also gained a memory of sailing a boat in a storm, even though he'd never been to sea. The second day, Lin Yuan discovered his phone charger was missing, and correspondingly, he gained a memory of how to play a piano piece called "Für Elise," even though he'd never touched a piano. On the third day, Lin Yuan couldn't find his half-empty bottle of shower gel, and all he could remember was enjoying French cuisine by candlelight. To be honest, it smelled really good. Next, he gained memories of "repairing a clock," "planting wheat," and "how Native Americans make boots," among other things. His brain was filled with an ever-expanding treasure trove of memories. And all he had to give up were insignificant little things like old books, chargers, and water cups. Until one day, Lin Yuan accidentally lost his ID card. This time, however, what he remembered was being covered in a sack and having his foot thrown into the river.
