MTL - The Legendary Mechanic in Marvel Universe - Chapter 50 found it

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 ͡°)

Global changes, calamities come, and monsters plunder.

In order to resist monsters, the global data will be digitized, and everyone will get a combat occupation or auxiliary occupation through awakening and transfer at the age of eighteen, and they will become stronger by killing monsters.

Lu Yan awakened the weakest fighting professional undead mage at the beginning, but obtained the professional support system, and the second awakening concealed the professional undead monarch.

“The necromancer is crispy, and it’s gone when touched.”

“This guy is really unlucky. Although he awakens to a combat profession, he is the weakest. He can also summon a few skeleton soldiers, which is useless.”

“And the number of necromancers is very small, basically there is no experience and resources to inherit, and the future is worrying.”

“Hahaha, I have awakened the Paladins, your Almighty King is here.”

Soon after, Lu Yan was wearing undead ghost armor, holding a ghost scythe, with an army of 100,000 undead behind him, and a scythe split the epic monster in half.

You said that the necromancer is weak, what does it have to do with my undead monarch?
