Chapter 453: In-depth Cooperation

"I can't help but wish I hadn't spent decades studying medicine..."

Hu Guojun let out a long sigh.

If he were a blank slate, he could have absorbed Su Wen's novel ideas like a sponge, but he was an old man in his sixties, and the knowledge already in his head had actually become an obstacle to understanding ancient Chinese medicine.

Collapsing and rebuilding his understanding was too difficult for a man in his sixties.

"Let's call it a day, then," Su Wen said with a smile.

He hadn't shared anything specific that day, merely helped Hu Guojun verify the authenticity of the books he had collected. Though ancient and modern Chinese medicine are of the same origin, due to a break in their transmission, they are like twins in a family who, after dozens of generations have passed, only recognize that they share the same lineage, while in other aspects they are entirely different.

"Hmm," Hu Guojun didn't push himself either.
