I often heard about time travel, but once I traveled through time, there was actually a fellow villager I didn’t know before. Zhang Sijiu, who was still a little confused at first, calmed down. After pointing out the way the fellow villager deceived her, she also got to know herself. New identity. Well, only eight years old? What? I was shocked to hear the bad news that my mother had a difficult delivery and her life was hanging by a thread? After finally rescuing one, Zhang Sijiu took the initiative to take on the responsibility of supporting the family. What should I do if the newborn has no milk to eat? Dr. Zhang rolled up Sleeve: Here I come! What should I do if the family is struggling to make a living? Dr. Zhang rolled up his sleeves. What should I do if the medical environment in Song Dynasty is poor? Dr. Zhang rolled up his sleeves again. Zhang Sijiu is full of confidence: As long as I can memorize medical books quickly enough , it will not be able to catch up with me despite all difficulties. As for fellow countrymen - Zhang Sijiu asked politely: Are you willing to dedicate yourself to medicine?
