The Hungry Fortress Wants to Build a Battleship in Another World – World of Sandbox - Chapter 19Vol 3. : Threat Creatures

SSR-ranked killer Mu Hui died in an explosion, only waking up to find herself transmigrated into the body of a vicious female supporting character in a book.

Nine harmonic zither chords shook the universe, who dared to not acknowledge the lord?

When Shen Yu woke up, he had accidentally gone into a ridiculous dog blood novel.

In the novel, he is a poor cannon fodder character, dead father and mother, fiancée runs away, drags a pair of legs and lives lonely in a 20,000-square foot mansion.

Later, in order to compete for the female lead, he died under the opposition.

In order to save his life, Shen Yu had to stay as far away as possible from the leading and supporting roles and concentrate on enjoying the luxury life.

As a result, one day, the servant brought a 10-year-old villain with bruised eyes: “Sir, this is the orphan of Tang’s family.”

Shen Yu: “…”

Shen Yu decided to adopt the small villains and change his fate.

Ten Years Later.

The villain pushed Shen Yu to the corner: “Who is that woman?”

Shen Yu: “… Who do you say?”

The villain: “The woman who seduced you at last night’s banquet! “

Shen Yu: “…”

The villain: “Hehe, I’m going to kill her.”

Shen Yu: “My son… That’s the female lead you forgot by the Lake…”

- 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.

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