MTL - Illimitable Until Death - ~ 157 I don’t even know it myself...

Lu Miao: “I counted, you will die in three days.”

Gu Erye: “With your good words, I’ve lived enough.”

Turn around and find a dragon in the feng shui cemetery.

Lu Miao stretched out her hand, “Wait a minute, I am familiar with this business, and the fat and water will not flow into the field of outsiders.”

Three days and three days later, Gu Erye was in a hurry, “When will I die?”

Lu Miao, “Don’t worry, right now!”

Three months later, Gu Erye was alive and well, his face flushed and he squeezed people into the corner, “Miao Miao, you saved my life, you must be responsible to me.”

Lu Miao, a top metaphysicist, somehow transmigrated into a poor little boy who didn’t love his father or mother, and he even gave him a dying fiancé as a gift.

Her parents expected her to die, her brothers and sisters in the Gu family hated her, and everyone in the city was waiting to see her laugh.

Lu Miao has a talisman in her left hand and Feng Shui in her right hand, playing with Feng Shui.

Big shots from all walks of life came to the door one after another, “We are willing to pay ten times as much as the Gu family’s bride price.”

Brother and sister of the Gu family, “Get lost.”

Gu Erye, “Thank you for the invitation, I have received the certificate.”

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 ͡°)
