you know what really hurts? the fact that up till the end, Qiu Qingzhi was still trying to protect Li Bing.

Over here Yi Zhi Hua reveals that from the very beginning, Qiu Qingzhi's motivations had simply been to protect Li Bing. He never meant for Li Bing to turn into a half-cat.

Even in the letter to the Empress he gives all the credit to Li Bing to ensure that he still remains in the Empress's favour

most of the letter just lists the motivations and crimes of Yong'an Elders, and concludes with QQZ giving the credit to LB, from what I can tell (source: trust me do not in fact, trust me)

He enters the secret room before anyone else to get the stone on the dagger for Li Bing: the only medicine that can turn him back into a human.
