She was bound to a poison art system, and in exchange for her life she would need to constantly poison people to gain longevity to survive.

Xu Lianjiao: "What should we do, living in a state where the system urges us to die every day?"

Originally, it was smooth sailing for the exchange of life, but she encountered a wonderful young woman from Butterfly Valley, the Medical Fairy ~ Feng Yu Chen!

Xu Lianjiao, after missing for the 108th time, glares angrily, "Spare me once and let me poison someone, can you?"

Feng Yuchen's eyes like a crescent moon and smiled kindly as she applied a silver needle: "No, I can cure all diseases, and I will cure you as usual."

"Don't believe you use your whole life to try?"

Xu Lianjiao:

I harm people and you save people, we are positive and negative, complementary eight characters, Yin and Yang harmonization, and heavenly rewards.
