Strange Rules: It doesn't matter, the system will take care of it.

Monster girls are women who are half-human and half-monster, with non-human features such as tails, scales, and wings.

The city of Luca, where the Sword Saint resides, is the largest city of monster girls on the Fire Continent. It is located in the center of the Sealed Cave, the Great Labyrinth, the Sleeping Dungeon, and the Sky Island. It is surrounded by four Demon Lords: Spider Queen Lilith, Slime Queen Alakana, Red Dragon Queen Gray, and Nightmare Queen Alice XX.

There are four demon king castles surrounding a human city that have not yet been destroyed, all thanks to Luca, the hero of love.

Five hundred years ago, in order to realize the ideal of coexistence between humans and monsters, the hero Luca embarked on a journey. He was not only powerful, having defeated several demon kings who enjoyed killing humans, but also gentle in nature and had never killed a single monster.

Ultimately, he married Alice XVI, the Nightmare Queen who shared the same ideals, and established a monster girl city where humans and monsters could coexist peacefully. In memory of this legendary hero, people called this place Luca City.

However, for unknown reasons, Luca City recently closed its teleportation tower, and now to get there, one must pass through the territory of a demon king.

Chen Feng naturally chose his niece's Sky Island.

When his apprentice Sika didn't come, his girlfriend Mei almost broke all three of Sika's legs when she heard that they were going to the Monster Girl Castle.

The unscrupulous merchant sells monster girls; he has enemies all over the world and can't go anywhere else.

So for this trip, Chen Feng only brought Xia Mei, the chubby-legged beauty.

"Mr. Chen, you're drooling. It's disgusting."

"Miss Natsumi, don't look at me with such disdain. I have absolutely no interest in catgirls or succubi, but as long as I can save the world and destroy the evil Undead King, I would be willing to sacrifice my body."

The two were chatting when they suddenly encountered a challenge.

"stop!"

As a neutral demon lord, Gray's dragon soldiers were quite easy to talk to.

"Either offer gold coins and gems, or offer delicious food, or hurry back."

He's good at eating, likes shiny things, and, apart from not liking to kidnap princesses, perfectly fits Chen Feng's stereotype of dragons.

Just as Chen Feng was preparing to use spatial teleportation to move a piece of the earth dragon beneath his feet...

Someone called out to him: "Hey human, over here, meow."

Inside a carriage pulled by celestial horses sat two travelers: a human male adventurer in his thirties and an orc female with cat ears and a cat tail.

"I'm Jill, a reviewer from a brothel who was invited to the Monster Girl Party."

"I'm Kyle Meow, who's heading to Karu City to look for a job."

"Should we chip in and get through together?"

So that's how it is. As long as everyone pretends to be a group, they only need to pay one travel fee.

Chen Feng glanced at the employment system and, after confirming that the person, the cat, and the driver were not hostile, readily agreed.

As soon as they boarded the carriage, Jill couldn't resist taking out a cigarette. Just as she brought it to her lips, she seemed to realize that smoking in an enclosed space wasn't appropriate, so she asked Chen Feng, "Does anyone else want to smoke?"

There are so many intermediate-level space travelers! They've even invented cigarettes.

Chen Feng waved his hand: "No."

Xia Mei recalled her experience of being transported to another world from the supermarket and said sadly, "I don't know how either. Sometimes I think, if I smoked and went to the smoking area at the back door of the supermarket, maybe I wouldn't have been transported."

Hard to say.

Because Uncle Sasaki, who smokes, also came over.

Chen Feng looked at Kyle Meow, only to see her say with a firm gaze, "Not a single one, Meow."

"Looks like I'll have to be patient then."

Reviewer Jill sighed and put the cigarettes in his pocket, but the next second he saw Kyle take a cigarette case out of his pocket.

Didn't we agree not to smoke?

Just as commentator Jill was about to speak, she saw Kyle Meow pour more than a dozen cigarettes into her hand, light them with fire magic, and then stuff them all into her mouth, performing an epic lung-bursting: "Awesome, meow!"

So that's why you don't smoke a single one?

The billowing white smoke instantly enveloped the entire carriage, almost making Xia Mei faint.

Chen Feng couldn't help but ask, "Can your lungs handle breathing like that?"

Kyle said calmly, "Lung pain means you're building muscle, meow."

Awesome.

Chen Feng remembered what Hei Mu had said: Sword Saint Hao Ge was a man with no flaws except for being a womanizer, so to find him, he would definitely have to go to the best shop.

Since Jill is a brothel reviewer, she must know very well which brothel in Luca is the best.

Thinking of this, Chen Feng subtly inquired, "Brother, you must work very hard, right?"

"It's alright, just checking out shops, taking photos, maybe even publishing a book or something." Jill pulled out a photo album. "This is a shop-checking guide I made using photo magic. Want to take a look?"

"OK."

Chen Feng took the photo album, and he couldn't hold back his emotions after turning just one page.

In the photo, Gil is seen in the same pose as Jiraiya from the Naruto anime, with his butt sticking out, lying on the ground, and sticking out his finger as if writing something on the ground.

Chen Feng turned to the next page and saw five large characters: "Beware of Hyena Men".

Xia Mei asked curiously, "What happened?"

Commentator Jill looked pained, as if recalling some unpleasant past events: "My butt hurts."

butt?

Chen Feng had guessed a little.

In nature, female hyenas are hermaphroditic, meaning that female hyenas also possess the ability to control their own sex, so Jill was... ...

Chen Feng dared not think about what would happen next, and could only salute: "This is the significance of the Survey Corps."

Reviewer Jill was deeply moved: "When we get to Luca City, it's my treat! You can choose anything you want, except for the elf shop!"

"No, no, but may I ask why there are no elves? Is it because elves think we humans are ugly?"

"No, it's because the elves look quite young, but they're actually thousands of years old."

"Shhh."

Chen Feng quickly checked the communication talisman on his body. Fortunately, it wasn't in use. Otherwise, if the legendary mage Flameng had heard it, she would probably have cried until the next century.

Upon hearing that the reviewer was going to a brothel...

Xia Mei blushed and said, "That's so shameless! I want to get off the bus!"

"Sigh! You must be a time traveler."

Commentator Jill seemed to have encountered this situation before, and patiently explained, "Customs vary from world to world. Take succubi, for example; they cannot eat food other than vital energy, and they will starve to death if they do so for too long."

"Before the city of Luca was built, the succubus tribe relied on capturing lone adventurers to survive."

"But that's a tribe. Some people say that if you get captured by a succubus, you'll die of pleasure. Whether those adventurers who were captured by succubi experienced pleasure or not is unknown, but they definitely died."

"Now that we have a shop, adventurers won't be killed by succubi, and succubi won't starve to death, so we're saving people."

Commentator Jill declared righteously, "A man should be responsible and have a sense of duty! The thought of a succubus lady going hungry makes me extremely anxious, and I wish I could rush into Luca City immediately."

Just then, there was a loud bang.

With a sudden explosion, the carriage began to shake violently.

The driver screamed, "Watch out! There's a monster!"

monster?

The four people in the carriage were all startled. This was Luca City, a place where humans and monsters lived in harmony. There were neutral demon kings all around. Where did this monster come from?
