The Witch's Empire Restoration Plan

Please tell me, when you are summoned to a different world by a witch and asked to revive a crumbling empire, what will you choose to do? Seager faced such a huge problem. A witch named Angelica summoned him to a country called Westland. At this time, the Westland Empire was in a mess. Its territory was divided by other countries, countless puppet states were established, the economy completely collapsed, and the nobles clamored to take power from the witch... As a summoner, if he wanted to return to Earth, he could only help the witch revive the country. Therefore, Sig could only start from scratch and formulate an "Empire Revival Plan." The economy collapsed and the finances ran out of money? Then borrow money from others. Territory divided into various puppet states? Then use the conflicts between countries to break the situation. Is the military required to be forced to disarm? Then use the police instead. ........... Years later, in an interview with the media, Sigurd, then the Prime Minister of the Empire, said: "I just want to go home."
