The Scum Villain’s Self-Saving System - Chapter 1

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 ͡°)

He Zening had always felt that novels depicting the life of a Company President were good for passing time, but insulting to the IQ. Still, having read countless novels of this genre, never did she imagine that someday she would transmigrate into one of them. To make matters worse, the plots were so similar that she could not remember which novel it was. She was left with no choice but to assume the role of a secretary to the President.

The secretaries in novels ran errands for the President, assisted him in pursuing women, helped him keep the flames of love burning, and even took the blame for him if necessary. But a real-life secretary? They were blamed by those in power, sometimes hurt and reprimanded wrongly.

If it were not for the excellent pay and necessity, she would have already bolted out of the door. And like all curious bystanders, He Zening wanted to see the plot happen before her eyes; the President meeting the protagonist! A villain standing between the love of the leads! The side characters!

This is the second life of a level-headed, diligent secretary working hard to achieve a carefree life, whilst being dragged into the plot.
