Galaxy Domination Guide - Chapter 442 - 433 The Great Transformation of Two Stars

After finishing playing mahjong, Yu Zhou, a recently resigned writer, returned home and found a young lady from ancient times, Xiang Wan, who was a former prime minister’s daughter, sitting on her sofa. After some simple communication, Yu Zhou, with her adolescent mind, accepted this “roommate” who had traveled through time.

On the other hand, Yu Zhou’s novel was adapted into an audio drama, which was unexpectedly performed by the well-known voice actor Su Chang, causing Yu Zhou to be overjoyed yet also in tears, because Su Chang was her ex-girlfriend.

Through their new connections, the girls re-examine their own lives and achieve personal growth. This absurd yet realistic experience may also “pat awake” Yu Zhou’s stagnant love life.

- Description from Novelupdates

Dual cultivation isn't a choice; it's a necessity.

After being struck by a truck like most lucky protagonists (or unlucky ones), Vaan found himself transmigrated into the body of an orphan in the world of witches and demons.

However, they didn't always exist.

Demons terrorized the world ever since the Gehenna Realm descended over 300 years ago. but along with them, came mana, giving birth to witches to combat these demons.

Since then, the world of men was dominated by witches, establishing the seven witch kingdoms, which safeguards at the forefront of the demon invasion.

In order to survive in the matriarchal society of the witch kingdoms, Vaan, like all other men who cannot use magic, had to learn how to service the witches to survive.

Nevertheless, it did not come without its own benefits.

Years of research have led the world to the discovery of intimacy between men and women could increase the witches' mana absorption.

But at the same time, men could absorb some of this mana to improve their physique and lifespan.

Thus, since then, an intricate relationship was formed between men and witches in the red-light districts. Love became casual, and dual cultivation is common.

As a prodigy in the art of pleasing women, Vaan lived a smooth two years since his transmigration as an orphan.

However, everything came crashing down in a heartbeat one day when his life was nearly taken, and Lady Eniwse whom he served went berserk.

Even so, that was not the end.

With the awakening of the Witch Hunter System, watch how Vaan takes on the world and becomes the lord of witches.

Note: Contains lemons.
Hunting witches does not necessarily imply killing witches if you know what I mean ( ͡° ͜ʖ ͡°)

The world’s worst offense, is called Love.

A prince sent into exile, without the means to fight back.
