Wizard+Fantasy Adventure+Multiple Heroines+Goldfinger
A servant named Garin in the Earl of Strice's palace usually acted domineeringly under the rule of the earl. Once, when he was forced to exercise the right of first night for the fourth young master outside, he did not arrive first. The person was a noble with the title of Lord. As a result, he was punched in the face.
After Garin woke up, he seemed to be a changed person. Under his guidance, the Earl's Mansion began to produce unique products one after another, slowly moving from the earl to the kingdom. The earl's industry spread to every corner of the kingdom until no one in the kingdom needed to buy their products, and they turned their attention to neighboring countries.
But at this time, Galin had no intention of caring about all this. He kept focusing on his wizard laboratory because his experiment failed again.
