I Was in Da Qin and Raised the First Emperor Hand in Hand

It is the twelfth lunar month of winter in Handan, Zhao State. Lin Wanwan, who traveled through time and became a humble maid, opened her eyes and saw three-year-old Ying Zheng being beaten and dying in the snow. An alarm suddenly sounded in my mind - [The Eternal Emperor Development System is activated! The host's health is less than 1%! Sign-in rewards will be reduced to a minimum! She picked up the bricks at her feet and shouted in front of Xiao Douding: "You can also touch my KPI?!" Relying on daily check-ins in exchange for cold medicine, hot meat buns, powerful pills and laxatives, she turned the dilapidated Proton Mansion into her own territory bit by bit. In the eyes of outsiders, she is a crying little palace maid, but she secretly makes all those who bully Ying Zheng cry for their fathers and mothers. She taught him the art of the emperor's mind, taught him the geography of the world, and used modern snacks to turn this violent and cold little bean into a sinister overlord with extremely double standards. When she was nine years old, she took the most noble child in the world on her way back to Qin, carrying gunpowder formula and steel smelting skills on her back. She will decide the position of the regent goddess!
