I Only Sell the Truth, How Come I Am an Evil God?

Even Miss Witch, the saint of the Church of the God of Steam, all of them devoted their loyalty to me. Ron came to a world where evil gods were watching, where the original was awakening in the wave of steam and machinery, and alien races were advancing on the imperial defense line with the blessing of the terror of the past. Even if he rose from a handyman to a noble class, he would not be able to survive. Fortunately, he had a forbidden library of truths in his mind. Ron exchanged knowledge and price in the dream he woven to master the power of the "Lord of Truth".

Lord of truth! The master of all forbidden knowledge in the world.
