This is a time of great powers: The vast Persia, Sparta that was founded by force, Athens with its trade and business, Thebes the rising star, The ambitious Macedonia, The twin heroes of the Western Mediterranean, The rising Rome and so on.

This is an era of brilliant stars: Agesilaus II – the last king of Sparta, Epaminondas – the Rising General of Thebes, Philip II – the founder of Macedonian’s hegemon, Dionysius – the tyrant of Syracuse, Camillus – the Roman dictator and savior…

This is an era of contention among a hundred schools of thought: Plato – the great philosopher, Antisthenes – founder of cynicism, Pythagoras – school of number, Democritus – the encyclopedia scholar, Hippocrates – the father of western medicine, Aristophanes – the great dramatist…

What will the hero bring to the world when he comes to this age as a humble mercenary through rebirth?

Perdi, known widely throughout the continent, is a very famous author of adult novels. But Perdi’s true identity is actually Vivian, the Imperial Night Librarian.

Vivian sends over the fourth draft of her latest novel to her publisher to be reviewed, but her work is criticized because the way she writes hetero s*x scenes isn’t erot*c at all.

“What? So you’re saying I’ll only know what sexual relationships are like after I experience it myself? But what can I do when I’m bound to a chastity contract?”

Unfortunately for Vivian, she had to sign a chastity contract in order to be hired as an imperial servant, and has been forced to remain a virgin ever since. Worse still, only a member of the imperial family could break the contract … but Vivian only has eyes for Ray, a mysterious man who visits the library every night.

But as it turns out, Ray is the imperial archduke and the emperor’s brother! One day, he approaches her with a sweet offer that she can’t resist …

Li Ya crossed the United States to become a high school student in Kansas, and accidentally acquired the friendship system.

The so-called friendship system is to improve the friendship value with friends, so as to obtain skills cards with corresponding capabilities.

“I got the star descent from Superman, the speed from the Flash …”

“From Batman … Um, why is the superpower obtained from the master rich? Why is it obtained from Thor? Hammer? Hammer?”

“I’m not targeting anyone, everyone here is … all my brothers!”
