A year after transmigrating, Lu Chenfeng had hoped to use knowledge from the future to lie flat and enjoy life. Things did not go as planned: at home, he had a foul-tempered widowed mother, a younger sister who was still a minor but had inherited their mother's personality, and a group of friends with lofty ideals who followed him everywhere.
In the first year of the Zhenguan era, Lu Chenfeng happened to use his modern medical knowledge to save Crown Prince Li Chengqian. This gave him the good fortune to meet the emperor and the minister Cheng Zhijie, and his fate began to change.
In this prosperous Tang dynasty, how could someone who had transmigrated like him be left out? If he couldn't do anything else, he could at least teach students, even if they were the crown prince, princes, princesses, or children of the nobility.
Well written. Very good writing. Come on, author.
