When a cockroach appears in a home, it is a pest that everyone hates.

But what if they were all concentrated in a food waste treatment plant?

It processes massive amounts of garbage for the city every day, without any cost.

Are they still pests?

In today's society, the government subsidizes hundreds of dollars for every ton of kitchen waste it processes.

A third-tier city generates tens of thousands of tons of garbage every year.

What is this? It's money!

Ye Tian, ​​a college student who came from the deep mountains of Miao territory, accidentally discovered that the Gu technique passed down from his ancestors could control and accelerate the reproduction of pests.

He embarked on a legendary life where he could raise insects, make money, and manage the environment all at the same time.

[Invincible + System + Regret + Multiple Heroines + Love Triangle]

In a world of high martial arts, one awakens a villain role system, enabling them to travel to other worlds, play the role of a villain, and extract the talent for playing a villain after completing missions.

...

Task 1: Play the role of the chief professor who killed the female lead's family, take in the female lead as his disciple and carefully train her, but ultimately be killed by the female lead when the truth is exposed.

"My beloved teacher saved me, but I killed him."

Task Two: Play the role of a simp who is unrequited love, fawning over the female lead and framing the male lead, only to be forcefully killed by the male lead in the end.

"Only when you lose something do you realize how precious it is. It turns out that my senior brother is to me what water is to a fish."

Mission Three: Play the role of a remnant of the Sin Clan who infiltrated the academy with the intention of breaking the Sin Seal to release the Demon Sword, but is executed after his identity is exposed.

"It's all our fault. If only we had trusted him a little more... He's not the sinner, we are."

Task Four: Play the role of a powerful hegemon in the Spring and Autumn and Warring States periods, who waged wars to conquer other states, only to die at the hands of his concubines.

"He was a tyrant, but also a wise ruler, and we destroyed this peaceful and prosperous world with our own hands."

Mission Five: Play the role of the mastermind behind an evil organization, relentlessly pursued by the protagonist group, and ultimately sacrificed for his great cause.

"God and demon, good and evil, I can no longer tell the difference..."

...

Behind every mission lies the truth of the world.

Unaware of the truth, Luo Chuan returns to the world of high martial arts with his villainous talents.

The heroines who remained in their original worlds couldn't help but shed tears of regret upon learning the truth.

I've traveled through time and space as a horse girl named Barbatos. I could have shot to fame at the League of Legends World Championship, but now, thanks to the system, I can only tearfully become Japan's top horse girl. As for my lack of talent as a horse girl? No problem! If I can't outrun others, I can always sprint. Huh? Even with sprint, I can't catch Silent Suzuka? Then I'll get Justice and Glory, Phantom Soul, and enchant my boots with Predator. Honestly, my hometown is quite high up, so a bit of highland blood isn't too much of a stretch, right?

I, Ares, transmigrated into the "Living Blood Alliance" from Harry Potter, and started out huddling together with six-year-old Tom Riddle in an orphanage for warmth.

[Ding! You have been bound to the Redemption System, nurtured the Dark Lord, and will be rewarded with heaven-defying magic!]

Others may fear and hate him, but I will spoil and love him, transforming him from a gloomy and pitiful little guy into the most handsome and academically brilliant student in the grade!

I used the power of the blood alliance to be his comfort pillow, and used system magic to help him slap the bullies in the face.

He said he wanted to live forever, and I pulled out a soul stabilizer: "Honey, splitting your soul will make you ugly."

He said he wanted power, so I pulled him together to form the precursor to the Death Eaters. I became the behind-the-scenes strategist, and he became the emperor in the spotlight.

Dumbledore sees me as a more dangerous mystery than Tom, and Grindelwald wants to capture me as his heir.

When I pulled out the "Key to Twin Souls," the two legendary fathers' pupils dilated in shock.

Albus Dumbledore: "Child, the color of your eyes..."

Gellert Grindelwald: "The markings on your body are my blood!"

Later, the whole school discovered that a beautiful consultant with heterochromatic eyes always stood beside the aloof Riddle.

He gave up making Horcruxes for me, reformed the Ministry of Magic for me, and turned the headline of the Daily Prophet into our wedding announcement.

#I raised a Dark Lord, but he seems to have developed a love-struck mind#

#Redeeming the villain and getting two powerful fathers as a bonus, this is a huge win#

(Harem-oriented, please don't enter if you don't like it) I'm weak, unlucky, and inexperienced. But that doesn't mean I can't do anything. Even if it's just for a day, a moment. There will always be moments I won't want to forget. A world where everyone is happy? I'll do it, so please watch. "I'm watching you! Don't use Den-O's lines seriously to flirt with girls, okay?!" Sawamura Eriri lashed out at her shameless ex-boyfriend Hanyu Aozora with her ponytail. "You can't even handle two people..." Kato Megumi pouted lightly, "Let alone Nino and Fumino." Eriri turned back stiffly, "So there really are?" "Yes, there are many more." Furious, Eriri used Starburst Stream Slash, with remarkable effect.

Dongfang Xing traveled through the world of Full-time Mage and found that he could see the entries above everyone's head!

And he can get one every time he advances a level!

First-order dual system, take it!

Natural soul seed, take it!

Little loach pendant, give it to me!

Mutant star, give it to me!

Mo Fan: "I thought only the Little Loach Pendant would use spirit essence to strengthen the Star. I didn't expect there are such idiots in this world!"

Mu Ningxue: "I thought being born with the Ice Seed was invincible, but I didn't expect Dongfang Xing to be even more terrifying. He was born with the Fire Seed!"

Zhao Manyan: "You call me rich? Are you kidding me? His magic has been strengthened to who knows what level! And why has his super-class defensive magic also reached the fourth level? What's even more terrifying is that his defensive magic is even stronger than mine!"

Mu Nujiao: "I've spent my entire life trying to follow in that man's footsteps, only to find that the gap has inexplicably widened!"

Liu Ru: "After sucking Dongfang Xing's blood, I seem to be invincible in the vampire world!"

Zhou Min: "How come this deskmate is both a jerk and handsome?"

Tang Yue: "I seem to have accepted a traitor?"
