Yin Yang Medical Sage

Su Mu didn't understand why his ancestors wanted him, the only child from a medical family, to learn three thousand words before he could inherit the Su family's medical skills; Even more unclear is why after listening to the words of his ancestors, one of his close relatives would pass away on the same day every year. In the end, he was the only one left in the entire Su family who was precariously ill with a terminal illness; It wasn't until the Liu family from outside, who were both enemies and friends, came uninvited that Su Mu finally got a glimpse of the truth... But I also grasped the life-saving straw that kept me alive.
