Everyone's an Emperor: We Agreed to Fight the Demon King, but We United the World

FREEDOM FANTASY WORLD, translated as Wonderful Fantasy World.

All the emperors of China's orthodox dynasties arrive at the same time in a fantastical otherworld called Odyssea.

Clad in imperial robes and carrying their quests, they find themselves scattered across a vast continent ruled by elves, beastfolk, and dragons.

The goddess's instructions are clear: gather together, team up and level up, then defeat the Demon King and save the world!

But when an emperor for the ages meets a ruler who lost his kingdom, when a founding conqueror reunites with a ruler who preserved what he built, and when sworn enemies are forced to team up...

Things gradually go off the rails:

Ying Zheng: "Oh? The Second Emperor of Qin is here too?"

Hu Hai: "I wouldn't dare, Father! I'm just a small, useless son of yours!"

Cao Cao, Sun Quan, and Liu Bei: "Damn it! Why are you losers on our team?!"

Sima Yi: "No way! Boss Cao?! You... you're here too?!"

Li Shimin: "Li Zhi? Come here and explain to me what this 'female emperor' business is all about."

Wu Zetian: "I am the holy maiden of the Grand Cathedral of Light, shepherding in the name of the gods! Who can kill me? Who dares?!"

Zhu Yuanzhang: "Well, well, if it isn't the Yongle Emperor Zhu Di! Come, come, commoner Zhu Baba and his unfilial grandson Zhu Yunwen pay their respects to Emperor Chengzu of Ming..."

Zhu Di: "Father! Father! Please don't do this! I'm scared!"
