MTL - In This Hogwarts Without a Savior - Chapter 10 is this optional

The Third Dimension is collapsing. The Fourth Dimension is descending.

First it seemed that only technology would evolve, but who knew the world itself could too? It wasn’t as simple as climate change or tectonic movement. No, the fundamental laws of physics that governed everything were changing.

Leonel was fairly lucky. His family was decently well off, his father loved him enough to brew vomit inducing nutrient rich smoothies every morning, and this was both the day of the National Championship and his 521st confession to his dream girl, Aina. As his father always said, nothing was more important than respect and persistence.

Unfortunately, everything changed that night. At the after party of ages, the world reached a saturation point and an apocalypse descended.

Abilities awakened. Sub-Dimensional Zones opened. Invalids rampaged through the Earth like a virus…

Those who could evolve would have a slim chance for survival. Those who couldn’t would die.

This novel will be a unique spin on the dungeon/system genre. Dungeons won’t be dungeons and the system won’t be a system… Take a look to find out what I maen :)

The prostitute of the Feng family was actually reduced to living in a haunted house.

At first, everyone thought that she would cry, make trouble, and hang herself, but she was quiet every day, without making noise, and set up a fortune-telling stall to earn living expenses.

A few months later, everyone in the Feng family invited her back.

She smiled and shook her head. Going back to the Feng family, there are no female ghosts to do housework.

Behind him, Lord Wei, who is the master of the city, aggressively embraced his fiancée in his arms, “My wife is timid, don’t scare her.”

All the ghosts who were caught, “Are you talking nonsense?”

Just when everyone was waiting for Master Wei to cancel his marriage with his nominal fiancée, they actually waited for the news of their engagement.

Outside the nickname, Master Wei married Miss Feng’s family.

Impossible, Mr. Wei is ascetic, mysterious and low-key, never letting women come within one meter of him.

Master Wei was full of smiles, “Nian Nian, where do you want to go to catch ghosts tonight?”

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 ͡°)

When other players are still stalking for how to recruit the Three Kingdoms, Qin Xiaobai already has such super-historical names as Baiqi, Hanxin, Chen Qingzhi, Yue Wumu and Zheng Chenggong.

Trembling players, see how I crush you with the All-Star Deluxe lineup. A little white screamed.
“Oh… wait, it looks a bit wrong, for the hair I brushed out some sister paper…”

妲 褒姒, 褒姒, Zhao Feiyan, Taiping, 婉儿, Wu Mei Niang…, said where the good names are going.
A little white surrounded by sister paper sighed: “I don’t want to bring my sister to the Three Kingdoms.”
