Valkyrie's Shadow - Chapter 10Winter’s Crown: Act 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 Miao transmigrated into a book, becoming the ugly, foolish female supporting character who behaved crudely, no thanks to being raised in a village. She kept hovering around the male lead and eventually provoked the female lead, who had a System, and was cheated into losing her company shares. Her own father married her off to a violent, abusive husband, and she ended her life as cannon fodder due to one of his violent fits. To avoid that tragic end, He Miao made two choices. The first was to escape the He family as soon as possible, while the second was…

Asking the male lead out for a meeting, she told him, “I don’t love you anymore. Let’s annul our engagement.” Jing Yan, who was still racking his brains on how he could get away from her annoying presence, exclaimed, “Are you serious?”Seeing that he was distrustful, He Miao took out the engagement gifts and stuffed them into his hands, ignoring his scornful reaction as she turned to leave. The annulled engagement meant half of her previous tragic fate was avoided, which improved her mood considerably. Hugging the little dog she adopted, she peppered it with kisses in her cheerful spirit, ignoring the fact that it stiffened in her arms…

Still, it started to act weird recently as it would run circles around her in the morning while throwing a fuss at night and trying to run outside, even succeeding a few times. He Miao consulted many veterinarians and experts on the matter, but she did not know that the dog’s rebellious attitude was because Jing Yan’s soul had transmigrated into it! Everyone knows that Jing Yan’s fiancee is an ugly, stupid, annoying village bumpkin who bugged him every day.

But she was at least tactful enough to annul their engagement. And yet, the same Jing Yan who had always acted high and mighty knelt in front of a fairy-like girl to help her put on her shoes as he asked unhappily, “It’s already been so long… Can we get engaged again already?”Everyone stared blankly, dumbstruck. Wasn’t his fiancee supposed to be ugly and stupid? She’s clearly enchantingly beautiful! Who spread those rumors in the first place?!

The Gura Gura no Mi is known as the strongest fruit in the world of one piece.
