Su Shen was a formidable soldier, but he never endorsed the idea of extreme and grueling training. In his opinion, training should be conducted scientifically – if one could master it, they should, and if not, then they weren't fit for military service.
When he recruited soldiers, he focused on finding those who could be trained scientifically, rather than those who needed to toil tirelessly, far more than others, to qualify.
He explained to Su Bing that the body needed refinement, not torture; tormenting the body to learn was impractical.
Hearing this, Gu Zi's eyes were filled with admiration. She thought her man had the potential to be a university professor.
Gu Zi also agreed with Su Shen's viewpoint that learning was something that required diligence but should prioritize maintaining good health.
Su Bing packed up his schoolwork and said, "I understand. I'm going to sleep now, goodnight, Mom and Dad."
