The Hidden Dungeon Only I Can Enter - Chapter 97 - On the morning of departure

As a man who had lived for 20 something years and had always considered himself as a straight man, he woke up one day and found himself possessed by a stupid and cute system. Moreover, it was a gong-shou cultivating system?! Let’s see how a shou with raised hackles evolves into a (pseudo)queen shou, incidentally with a story of a hidden loyal dog gong.

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 ͡°)

When Li Yu woke up, he found that he had traveled to the game world of “Avenue Eternal”.

At this time, there is still half a year before the player arrives.

The evil demon catastrophe has not yet begun, and the forbidden areas of death such as the rotten swamp, the golden desert, the ghost country of the Yinshan Mountains, and the boundless monster sea are still silent. The whole world is calm.

Li Yu took advantage of his foresight and took advantage of the opportunity to develop wretchedly.

After the game is launched, along the Qingshui River, players often see a senior NPC with a glittering ID fishing.

Whenever the players approached excitedly to chat to see if they could apprentice or trigger tasks—

“What? You want to worship me as your teacher?”

Li Yu shook his head: “Excuse me, your qualifications are too poor. But Pindao once lost a Chilong jade pendant in the zombie cave. If you find this thing, I can teach you a spell.”

“Do you want to learn alchemy?” Li Yu smiled slightly: “There is a group of evil cultivators in the Wugui Cave of Qilao Mountain, as long as you can eliminate the evil for the people, and bring their magical instrument Xinjin and copper bottle to me, How about Pindao passing on your alchemy skills?”

“You want to worship Zixia Sect?”

“Do you want to learn alchemy?”

“It’s all right.”

Li Yu said meaningfully:

“But you have to understand one truth, there is no free lunch in this world!”

…

It was not until hundreds of years later that many top figures fell and disappeared, and the players also changed one after another, but Li Yu was still active in the world of dry ground, and he was even about to rise through calamity.

Many players have to sigh: This NPC is too strong!
