In fact, Su Yanyi wasn't exactly a paragon of virtue herself; she couldn't care less about mistresses. But when someone wanted to become a mistress to her own family, she couldn't turn a blind eye, especially since that woman had attempted to murder her in a past life. For someone like Su Yanyi who believed in revenge, there was no way she would let it slide!
Kang Zhong stopped talking and continued with his tasks, but he felt somewhat puzzled.
Kang Zhong was an orphan who had been adopted by the Su family at a very young age. Based on his talents and special skills, he underwent training and, after passing numerous selections, eventually became Su Yanyi's assistant. His understanding of the Su family went even deeper than Qin Jiran's, which is why Su Yanyi would entrust her plans to Kang Zhong.
