Fantasy: Summon the Heavens, I Will Fight for Hegemony

[Invincibility + Hegemony + Harem + Don't overwhelm the protagonist, don't overwhelm the realm] Gu Changan traveled to a fantasy world where demons were rampant and became the sixth prince of the Daqian Dynasty. At this time, the undercurrent of the Daqian Dynasty was surging. The Emperor of Daqian fought with the big demon and died of serious injuries. The prince also died suddenly. The weakest prince, Gu Changan, was pushed to the throne by Queen Mother Liu Ruyan and became the puppet emperor. The Queen Mother listens to politics behind the curtain, and the ministers in the court are constantly fighting with each other. The vassal kings in various places are divided, demons are born, the rivers and lakes are bloody, and the enemies outside the country are waiting with eager eyes. Just when Gu Changan came to the throne, the system started, but this system was a bit strange. [At the age of 35, Daqian is in turmoil, demons are rampant, wars are everywhere, and the people are miserable. You are about to become the king who will destroy the country. You stand on that high platform, looking back on your life like a puppet. Your heart is full of regrets. You feel ashamed of the country, the people, and your ancestors. You decide to jump off and end this absurd life! [Ding! It is detected that the host is in dire straits, and the counterattack system has been activated to help you revive! Looking at this information, Gu Changan looked confused. No, I have just ascended the throne, why do I need to restore the country? Isn't this rhythm a bit strange? However, although the system is sick, it is still powerful. The Saint Realm Cultivation Card at the beginning made him invincible from then on. Bite!
