Lu Lingxi died.

As a child born by his parents through precise genetic matching, for eighteen years of his life, he lived entirely for his brother, who had leukaemia. He was his brother’s shadow, a “medicine reserve bank” for his brother’s treatment needs.

Umbilical cord blood, stem cells, bone marrow… whenever his brother needed it, he would have no choice but to quietly lie on the operating table.

Until the last time, when his brother needed a kidney and he never came off the operating table.

When he opened his eyes again, Lu Lingxi became a teenager with the same name Lu Lingxi.

Freed from the shackles of his fate, he possesses the mysterious ability to communicate with plants.

Raising flowers, gardening and running a farm, Lu Lingxi begins a very different life!

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 ͡°)

Lu Gu got a marriage on behalf of his brother and married the fierce hunter in Qingxi Village. No matter how wronged he was, under the coercion of beatings, he was still put on the sedan chair.

How could the Shen family gave up on marrying such a ridiculous thing. After a tumultuous fight, Lu Gu was brought back to the Shen family. He was ready to tremble and seek life.

Who knew that the days after marriage were far less difficult than he imagined, and he could even fill his stomach without having to be beaten. Shen Xuanqing also bought him chickens and ducklings, and built a fence in the backyard to raise chickens and ducks for him. Lu Gu squatted in the backyard and touched the chickens and ducks. After the panic, he was full of joy. Shen Xuanqing said that these were all his.

For the first time, Shen Xuanqing, who was about to go out was stopped by Lu Gu timidly, holding the corner of his clothes. He saw his little fulang showing a short and shy smile, handing over a small bag of fine flour cakes, saying that it was the food for him who was going into the mountains.

Shen Xuanqing was nibbling on the cakes expressionlessly in the mountains, but in his heart he was thinking that the little fulang was good and diligent. He looked good when he smiled, but he was too thin.
