"I didn't. I endured it all." Nathan shook his head, thinking, 'I have seen plenty of this scenario playing in those cultivation type novels. If they are experiencing pain, they will have to endure it and can't pass out. The moment they pass out, their body will explode. That's why I endured it to the best of my ability.'

"Yes. Is there a problem?" Nathan frowned.
"What is actually happening to your body when you ingest the core?" Vivian moved to the blackboard on the side and grabbed a picture of human anatomy.
