Dear Concubine, Please Give Me Tea!

Just to help the master collect medicine and then die? God is unfair, I died on a cliff at a young age, and I will take the exam tomorrow. Ahhhh, after rebirth, I landed in a magical country, just like in ancient times, but this is a world of spiritual beings and alchemists, which has not been recorded in history. Moreover, I have an inexplicably cute and sinister son. He is only 17 years old. Although he has already had it since he woke up... In this useless body, I will create miracles and make everyone look at me with admiration. This novel and its characters are purely fictitious.
