In the serene bedroom, Aizen sat upright in the grand master's chair.
His eyes were slightly closed, hands resting on his knees, and his posture straight as a spear. His legs were aligned with his shoulders, making him appear like a statue as he sat there.
This was seated meditation. His breathing was even and long, circulating internal energy through his body's meridians and acupoints.
Suddenly, he opened his mouth and took a deep breath, causing the room to stir with a faint wind, as if he had inhaled all the air within several meters around him.
"Gulp!"
He swallowed this breath mixed with saliva in one motion, as if he had swallowed a solid iron ball. The breath fell into his stomach, making a low humming sound.
His intestines began to move, and an electric-like sensation coursed through his entire body.
