What is the reason why "The Temptation of the Cat Demon" killed Sue?

The obsession with love is too deep. Sue didn't die directly when she was shot by an arrow, but she lost consciousness after saying a word. Why is this sentence? Although there are only three children, it can be seen from the heart that Sue has a deep love for Shen.

Only when you love deeply, will you absolutely trust him and die unwilling. Su Qing is unwilling to believe that Shen really killed her.

The deeper you love, the deeper you hate. It is because of your hatred for Shen that Sue can't be reincarnated. I have been waiting for Shen under a tree in the underworld for thousands of years, but I firmly believe that Shen will come to me. But time will wash away feelings. After waiting for thousands of years, her hatred gradually faded and turned into expectation.

Extended data:

Su/Su Ranran used to be the owner of Sujia Fairy Palace. He used to "fly for nine days to catch birds, dive deep into the sea to tease dragons, fight evil ghost villages in the south and kick strange old men in the north".

I met Xuan Huazi Shen Moqing in Meixianlou and fell in love with him at first sight. After several twists and turns, they fell in love and were finally shot by Shen for unknown reasons. The soul did not want to be reborn, and waited for thousands of years by the forgotten river, without waiting for Shen to appear.

After revenge, she got soup from Yan Hanjun at the expense of becoming his princess, and kept her memory, and was reincarnated as Su Ranran. However, due to side effects, she suffered from schizophrenia. One wants revenge, and the other still wants to pursue Shen Moqing. In the meantime, she played a lot of jokes and was almost stunned by Zhao Qingshan.
