A doctor from Modern Science and Technology traveled through time and became Xiao Jingyue, the fetus of Concubine Ye of Daning Kingdom. She relied on the special ability of "the voice of her heart can be heard by the tyrant father Xiao Yongqian" to save the Ye family who was framed. Xiao Jingyue brought the golden finger of the system and used modern knowledge as a child to help her father rectify the government, promote sweet potatoes and other high-yielding crops, put down the rebellion of King Zhang and the foreign invasion of Beidi, break the prejudice that "women cannot be kings", and was established as the crown princess. After Xiao Yongqian's death, she ascended the throne as emperor and implemented new policies such as frivolous corvee and low taxes, construction of water conservancy projects, etc., And ultimately built the Daning Kingdom into a peaceful and prosperous era where officials governed the country and the people were happy.
