Rogge is a mechanical engineer who, after transmigrating into another body, becomes a slave in a robot territory, facing the threat of being killed at any moment.

He uses the advantages of his ring world to quickly earn contribution points and stockpile resources.

Through research and storage of items and living creatures, the ring world itself begins to change.

Time passes twice as fast inside. He grows all kinds of food, takes in slaves, forges weapons, and advances civilization...

After winning over numerous slaves and acquiring a large cache of robots' technological equipment, he frees many of them, escapes the Northern Ridge base, and heads to the territory of the wizard clans.

He steals the wizards' power and disguises himself as a noble lord among them.

In his new territory, he develops a technological civilization, builds a System, and ushers in the age of biological genetics.

Leading numerous human subjects, he wages war against demons and blood-touched creatures, brings beastmen and wizards under his command, and creates a new robot race... He embarks on the road to rising from the abyss.
