Global Lord: My Unit Commander is Vampire Queen - Chapter 15: War Council of the Damned

One morning after being struck by lightning, Ye Wenxuan inexplicably gained the superpower of being able to generate electricity.

If he jammed his finger into one of the generator terminals in an electricity power plant, he could provide a year’s worth of power for 3 Tier 1 cities simultaneously, receiving the name “the mobile nuclear power plant.”

The country’s electrical company’s boss held his hand, speaking emotionally: “Comrade ah, the country’s future electrical development will all depend on you!”

Ye Wenxuan: WTF

Later, the “mobile nuclear power plant” was dispatched to be a bodyguard for a local tyrant.

Xing Yuan coldly said: “Just now did you or did you not electrocute me?”

Ye Wenxuan pointed to the heavens and swore: “I am an honorable employee, how could it be possible for me to make a move on my employer!”

Later on…

he made a move.

Yang Qing never expected that he would travel to the fairy world, let alone that he would have a chance to travel back.

It’s just that after I came back, I found out that this world is not friendly to cultivation, and it’s a completely degenerated world, so what else can I do?

Part-time work is not allowed, so he can only rely on the rune technology of the fairy world and develop a little black technology to live his life, so his eyes are directly fixed on the moon above his head, where his dream begins!

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 ͡°)
