Tachikawa Shin always thought he was a decent, upright man—unfortunately, he’d been saddled with an indecent favorability system.Raise others’ affection to grow stronger?“I’d rather stay away from these witches, but this concerns my safety and physical integrity... Well, it seems I don’t have a choice,” Tachikawa Shin said righteously, with absolutely no perversion whatsoever.All hail the Rizzler!

In a world dotted with World Entrances to a demon world, demons have invaded humans for centuries. Humanity has united and one of the most ancient sects in the world, the Archean Mountain Sect, has set up an entire education system in the form of Dao Academies and defenses at the World Entrances.

Fang Ping was blind. By chance, he transmigrated to another world. Upon his arrival, he was ambushed by a ferocious beast. Fortunately for him, he was rescued by a woman. After being saved, he discovered that this world also used English. However, to his surprise, the denizens of this world had proficiency below that of a kindergartener from his world. Yet alone say an entire sentence, they even fumbled about pronouncing single words.

Coincidentally, he awakened the Master Teacher System. In order to repay them for saving his life, he decided to stay and teach them English.

He began by teaching them to recognize the alphabet and then phonetics and finally began to teach them vocabulary.

However, Fang Ping was unaware that his students were abnormal. They were the famous night elves, and the person who had saved him was the next queen of the night elves clan. She was the daughter of the current queen.

The English that he was teaching was the vocabulary of this world’s magic spells. Hence, the weak night elves began mastering magic spells and their forces grew powerful once again.

Five years later, Fang Ping opened his eyes.

He looked at the people of all races kneeling before him. It was as though a whole country had come to the royal court. There were giants, dwarfs, fox demons etc. Beside him, the sexy, stunning queen of the night elves was looking at him with a worshiping gaze. Fang Ping finally realized that he had taught them some incredible things.
