I Summon the Sages to Make the Empire Great Again

Great news! The welfare of the time traveler has been greatly improved, and you can directly become the emperor of the empire after crossing over! Bad news, only one capital city remains. The demons have reached the gate of the capital, but the nobles are still harboring their own agendas. There are no taxes, and the army is still being mobilized. Even the Holy See, which pays money every year, comes to sell indulgence scrolls! The elves secluded themselves in isolation, and the demi-humans were in turmoil. Fortunately, Slade successfully contacted the sage. Take my first move to make distant friends and close attacks! Another move from me will make Li Daitao stiff! Slade stood on the city wall when the capital was about to be breached, holding the holy sword high in his hand. "If the Holy Light believers are not willing to take off my head, then work with me to repel the demons and make the empire great again!"
