Fan Jin found Gong Cheng Lei very quickly, and the answers he got from him, left him in a state of shock.
He gathered that Ning Rui had been helping Fan Qi to source out tonics suitable for recuperation for many years and Ning Rui had frequently visited Fan Qi's personal kitchen. When he thought back to Jun Wu Xie's guess, Fan Jin had to seriously consider that possibility no matter how much he hated to.
Ning Xin had masterminded an attempt on his life, and her father could very possibly be the very culprit to have drugged Fan Zhuo's meals to kill him.
Fan Jin was greatly shocked and heavily devastated. He could not make himself imagine that the two people he had trusted so much all this time and treated almost like family members would deliberately plot to kill him and Fan Zhuo.
With a numbed and heavy heart, Fan Jin brought and shared his findings with Jun Xie and Fan Zhuo before he left with heavy steps.
