Crown of Thorns Northland Dragon

No system + single female protagonist + slow pace + the author digs many pits + multiple races + an alternate world and an imaginary continent + the history of the continent + the early pits have been dug On a continent full of races, Fang Chen, a fusion body who escaped from the Human Race Research Institute, and researcher Lingyue were pursued by the empire and embarked on the road of escape. They went home, found relatives, said goodbye, founded a country and conquered... A wonderful life begins with escaping from the laboratory. There is no system, the world is too big, and the pace is slow. I focus on digging holes in the early stage, and fill them in after chapter 50. You can keep it up.
