There's Something Wrong With This Account - Chapter 127 - : 127, [Bumper Harvest]

She, a modern hidden ghost leader of an organization which gathered insane prodigies proficient in the various differing skill-sets. Highly skilled in medicine and poison, executes covert assassinations, viewed as insane and demonic in the eyes of people of the world. Killed in an accident, and reborn into the body of a disfigured young girl.

What? Face disfigured, identity stolen? A return to the family dim and hopeless? Her identity can be given up, her family can be forgone, but as for the one who harmed her predecessor who inhabited this same body, if she didn’t at least make them scream in unimaginable agony and throw them into a state of wretchedness, how could she live up to her demonic reputation? Endless turmoil ensues and it’s a battle to dominate over all! See how she shook the world dressed in a suit of red, her sword up against the dominant powers that rocked the Heavens! Her name spread across the seas, shocking the earth!

The apocalypse has not yet begun, but the system has arrived early.

Then Chen Mo’s style of daily life suddenly changed.

You can get rewards for eating and petting the dog, and communicating harmoniously with beautiful women is regarded as a battle with the ninth-level corpse king!

[It was detected that the host was so brave that he fought the ninth-level zombie king until he lost all strength. Since the target level was too high, the host could still get points as a reward even though he had not completed the kill by overstepping the level of the enemy. The host is hereby rewarded with 5,000 survival points and an A-level gift pack. 】

Chen Mo, who had just finished the battle with his schoolmate, couldn’t help but have a strange look on his face when he looked at the translucent floating window in front of him and the harmless schoolgirl beside him.

[It was detected that the host had tamed a fifth-level mutated corpse dog. Because the target level was too high, the host jumped over the level to tame the alien beast, which is unparalleled in charm. We hereby reward the host with 2,000 survival points, a B-level gift pack, and +50 charm! 】

Chen Mo, who had subdued a wolf dog with snacks, listened to the prompts in his ears and felt quite fucked.

Chen Mo lives a normal life, but in the eyes of the system, his life is full of monsters and ghosts.

This resulted in Chen Mo being able to trigger various rewards with every move he made. When the end of the world came, Chen Mo’s rewards would be maxed out, and his combat power was incredible!

- Description from novelbuddy

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 ͡°)
