So, he patiently guided the blood to flow out of his body. It was a delicate and tedious process.
He had to give his body enough time to generate new blood, ensuring he didn't die from blood loss.

Harry held his breath during the process—not literally, but his focus was absolute.
"Ufff," Harry sighed, wiping the sweat from his forehead—though none was there.
A puddle of blood lay before him. He collected it in a container and stored it in his space ring.
He could already hear students walking and chatting outside. He wasn't sure how much time had passed during the process.
