The Whole Country Develops a Different World

When he woke up, Xia Xuan found himself transmigrating into a different world, the emperor of a constitutional monarchy.
Xia Xuan originally thought that he could be a mascot honestly and enjoy the glory and wealth, but there was another system in his head? !
Ding dong!
A new world has been explored, please confirm the world information as soon as possible.
“New world?” Xia Xuanyi waved and a black door of space appeared in front of him.
“Do you enter in the form of a door? This will give you a lot of room for maneuvering.”
“Come on, give me a call to the Prime Minister of the Cabinet immediately.”
Ps: Enter “Goblin Slayer” first, and “Scarlet Eyes” and “Life in a Different World from Zero” will be added later
