Chapter 1664: It's impossible to predict in advance

"Good for you!" Su Yun looked at him with disdain."It's not a big deal."

Zheng Ren knew that Su Yun was just making a passing remark. If his mental fortitude was as good as what he said, he wouldn't have returned to Haicheng back then and prepared to give up his medical career to become a veterinarian.

To be honest, it would be a huge loss for Su Yun to give up on clinical practice.
