Either E Or S Class: I Will Kill All Vampires. - Chapter 25: Ch : Adapt.

Inexplicably, there was an app on Jiang Yu’s phone that couldn’t be uninstalled. After a suggestive opening animation loaded, a sentence appeared on the screen: … What is your wish that you most want to realize?
Jiang Yu, who doesn’t believe in ghosts and gods, couldn’t hold back after all, and made a wish for her parents to be resurrected.
Then the screen restarted, and a new line of words was displayed in the center of the phone——
[Welcome to the world where power is paramount. 】
Waking up again, Jiang Yu was in a strange bus, next to a player in the same situation as her, and the announcement sounded in the car: “There is an experienced person among you, please find out his existence.”
This is the beginning of the infinite world full of horror.

In a dungeon, Jiang Yu met Shi Jun, who was the number one ranked S-100% under the alias of “Zhong Yu” disguised as a rookie.
At this time, Shi Jun pretended to be a soft and weak little white flower, while observing Jiang Yu closely.
Her eyes on Jiang Yu were full of interest. Seeing Jiang Yu’s calm, rational, and heart-warming performance, Shi Jun couldn’t help but smile slightly.
No one can live without shame in this infinite world, but this person in front of him is an exception.
While pretending to be afraid, Shi Jun took the other’s hand, while lowering her eyes to hide the smile in her eyes.
Such beautiful roses made her want to pick them, plant them in her own garden, and taste them to her heart’s content.

The infinite world is full of dangers, and even if Jiang Yu has a calm judgment, she still struggles.
But she knew that she could not retreat, otherwise not only would she not be able to realize her wish, she would even die without a place to bury her.
At this moment, a woman with a strong fragrance of flowers found her, and pointedly tapped Jiang Yu’s lips: “Surviving, escaping, and fulfilling wishes are all difficult things for newcomers. If you are not careful, you will be smashed to pieces. But-”
“I can protect you, but I only protect one kind of person, Little Rose, do you know what kind of person it is?”

At first, Shi Jun just wanted to pick this rose.
Later, Shi Jun wanted to keep her for a long time and let her bloom in his palm.

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.

Hunting witches does not necessarily imply killing witches if you know what I mean ( ͡° ͜ʖ ͡°)
