Marrying the Empress at the Beginning, the Demons Came to the City

My name is Su Ming, and I accidentally traveled to a fantasy world. Like many time travellers, I was lucky enough to activate the god-level sign-in system. By signing in, you can get what the world dreams of. I know very well that there is heaven outside the world and there are people outside the world, so I have been developing in silence. It wasn't until I was twenty years old that I was promoted to Semi-Saint and was granted marriage by the Empress. And the object of marriage is the current Empress Feng! ... My name is Xue Ningshuang, and I am the Empress Dafeng. Dafeng has declined and has been passed down for thousands of years. Now it will perish in my hands. The demons are wreaking havoc in Dafeng, and the princess of the demons wants to marry the most beautiful man in Dafeng. I refused to let her get what she wanted, and gave her a marriage to Su Ming when the country was in ruins. However, when the demon army was attacking the city, a giant suddenly stood outside the city, trying to hold back the great power of Fengtian... "There is actually a strong semi-saint in Da Feng?" "The great general will rise!" "Who is this person?" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
