"You underestimate my medical skills. Do you think I resurrected Lu Changqing purely by relying on spiritual pills and elixirs? Your medical skills are nothing compared to mine! From the very beginning, I suspected that something was off with Mr. Qiao's illness. Although rheumatoid arthritis is difficult to treat, it wouldn't have got to this severe stage when he's only around fifty with your medical skills."
"When we arrived at the Qiao's house, you and Qiao Yuanfeng were exchanging secret glances, plotting something. Others might not have noticed, but I did. After examining Mr. Qiao, I found his body was already severely poisoned. And thus, I was certain that you were responsible. You are indeed skillful in poisoning, if a person doesn't have excellent medical skills they really won't be able to discover it."
After Su Chengyu explained, Jiang Qi was completely disheartened.
