Lin Feng, a modern social animal, was reborn in a different world, Odyssey, and became Karl, the son of the deposed Demon King. Magic and steam technology coexist here, but the social class is strict and the common people are exploited by the nobles. Karl originally wanted to live peacefully, but when survival and death were in front of him, he had to use the only modern knowledge he had to lead the people at the bottom to launch a "Red Revolution" to overthrow the Holy See and aristocratic rule, establish an equal republic, and at the same time fight against the invasion of external gods.
"I don't want to be like this, but this world is too worth complaining about," Karl said helplessly.
