In the vast, shadowy expanse of the library, rays of golden light materialized around Jacob, illuminating the ancient tomes that lined the shelves. The air was thick with the scent of aged parchment and ink, a comforting aroma that felt like home. As he stood there, a tingling sensation coursed through him, and dozens of acupoints belonging to the beast race began to open up within him. Each acupoint felt like a small door unlocking, revealing a pathway to newfound power and understanding. At that moment, a profound sense of enlightenment washed over him; he could feel the very essence of his humanity blending seamlessly with the primal spirit of the beast race, creating a fusion of strength and intellect.
