The first time they meet, she bumps into him. The second time they meet, she agrees to a marriage contract in exchange for his help in her bid for revenge. But… he becomes addicted to loving her.

During his first attempt, he flies a helicopter domineeringly; in his second attempt, he arrogantly removes all his love rivals; in his third attempt, he tries to tie her down using a cute child. Youxuan replies with a plain resounding ‘no’ all three times.

In the end, Shan Hanjie takes one look at her, grits his teeth, and plops onto the ground. “Babe, you dropped your prince charming, please bring him home!”

Su Leyun, the legitimate daughter of the Hou family, was replaced by a peasant woman during a plague when she was still in her infancy.

After experiencing hardships in life for more than ten years, she finally returned to her parents, but she was plotted and framed at every turn. She was even looked down upon and treated coldly because she grew up in the countryside.

She originally thought that her sincerity would impress her husband and win him the gift of betrothal, but she didn’t know that he only married her for the sake of pretending to be a match.

After resurrecting her life, she vowed to make those who bullied her pay the price. She knew what it meant to be respected as a legitimate daughter!

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.
