In the wee hours, Gao Yang returned home to find his mother and sister already asleep.

He tiptoed through the living room, closed the bedroom door behind him, and pulled out a reference book titled "Prisoner Fitness" from the bookshelf.

The book was packed with practical advice on how to exercise alone in confined spaces to strengthen the body, achieving results comparable to gym workouts.

Gao Yang had bought this book before his Awakening, during a time when he felt too frail and wanted to build up his physique. However, after flipping through a few pages, it ended up gathering dust on the shelf.
