[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.

The entire population is transported to the Dragonspine World, a world named after the Dragonspine Tree, where giant trees hundreds of meters tall can be seen everywhere.

Each player can start by binding a Dragonspine Tree as their sanctuary and can also randomly select a talent.

Chen Shu woke up to find himself in an unfamiliar forest, and in order to survive, he had no choice but to keep striving.

His talent is "identity playing," which gives him a random identity every day and grants him the corresponding abilities and traits.

From then on, his most anticipated thing every day was to refresh his identity.

[Resource Sighter]: Passively senses all basic survival resources within a 500-meter radius and highlights them within the field of vision.

[Beginner Trap Master]: Can create efficient and concealed beginner traps.

[Forced Philanthropist]: You will receive blessings when you voluntarily give your own resources to other survivors who are obviously in distress. You can only gain by giving.

[Shady Merchant]: When conducting transactions, they can always keenly perceive the other party's most urgent needs.

【Gambler】: Every four hours, you are given two unknown survival blind boxes. Choose one to open. The items inside are completely random and vary greatly.

[Stolen Goods Appraiser]: Can detect the original owner's marks left on items and trace their origin from video clips.

...

While others are struggling to find food every day, he's already living in a penthouse...

In the wild continent, countless races coexist, and the law of the jungle prevails.

Upon arriving in the desolate continent, Lin Feng discovered that the human race was one of the weakest races there. Despite their large numbers, they were subjected to captivity and enslavement by other races.

In his moment of crisis, Lin Feng unlocked the "Rise of Humanity" system, which allows him to summon creatures called "players" from another world to help him expand his territory.

The Fourth Calamity descended, and from then on, no one could stop the rise of humanity!

Traveling through the primordial world, watching Pangu create the world, activates the Infinite Download System.

With the system, one can download other people's supernatural abilities, treasures, cultivation techniques, and cultivation levels...

Qin Tian's first world was downloading the cultivation of the Great God Pangu.

From then on, the primordial world had one more terrifying being that dominated heaven and earth.

Oguro, who was transported to the world of One Piece, witnessed the brutality of the pirates firsthand.

At this moment, all talk of passion and freedom becomes a lie!

Divine Kingdom System! Summon the Gotei 13!

Four Emperors? Three Admirals? I have thirteen captains!

The Five Elders? The Knights of God? I have Squad Zero!

King of the World, Im? I am the Soul King, ruler of all Death Gods!

It's a world full of death and slaughter, so it's not unreasonable to use the Grim Reaper to suppress it, right?

Since there is no pure land in this world, I will carve out a pure land with my own hands!

(This is a Warhammer 40,000 fan fiction. Some timeline settings may be slightly modified, but it will still be very Warhammer-esque.)

(It will incorporate some references to memes and historical events... to expand the drama and fun of this fan-made universe.)

While driving home with his girlfriend, Empress, a Chinese college student studying in the US, Xiao Li was suddenly sucked into the Warhammer 40,000 universe by a warp vortex...

It turns out that his girlfriend was actually one of the Emperor's soul fragments!

.....................

Suddenly dumped on a desolate planet, just as Xiao Li was about to be chopped into mincemeat by orcs, a panel suddenly appeared before his eyes...

Things seem to be getting... interesting!

Good news: Nakano Yuri has received the golden touch of hard work paying off.

Bad news: This is just an ordinary world. I thought I was going to live a peaceful life as a dragon king, a literary master, or something similar.

But unexpectedly, he joined the multiverse chat group.

Thus, the worlds welcomed a great demon king who defied the heavens.

Give him a breathing technique, and he mastered it on the spot, innovated upon it, and won over Kanroji Mitsuri;

Lin Siya never imagined that a simple outing would lead to her being transported to the 1970s by a mudslide. The 1970s were fine, though resources were scarce, but as an orphan, she didn't mind. However, she never expected that it wasn't just a simple time travel, but a transmigration into a book, becoming the female protagonist's comparison point. Even after death, she was constantly being compared to her. Lin Siya was furious…

[Intelligence system + urban slice-of-life + spy agents + multiple female leads]

Chen Yang lost his job, his father was seriously ill, and he couldn't afford surgery... He unexpectedly awakened the "Daily Intelligence System".

[Intelligence 1]: In half an hour, you will experience a car accident, resulting in the destruction of the car and your death.

[Intelligence 2]: There is an A-level wanted criminal in the neighborhood where you rent a room. The bounty is 100,000.

[Intelligence 3]: On the antique street, someone found a bargain at a low price and made a profit of 100 times.

[Intelligence 4]: The beautiful doctor is tossing and turning at night, and has developed wicked thoughts about you.

[Intelligence 5]: Evergreen Company, whose boss is a spy, poses a huge threat.

Chen Yang used intelligence—

Dating, catching spies, making money, raking in hundreds of millions.

A shadow spy from a small island nation died with his eyes wide open in disbelief.

"Impossible! I was born and raised in the Dragon Kingdom... How could you possibly see through this?"

The top assassin from India is in a panic:

"I've been hiding for three years without anyone noticing, how come I'm exposed the moment you arrive?"

A veteran special agent from the Dragon Kingdom looked helpless:

"Can't you be a little more discreet, kid?"

"You've caught all the spies and taken all the rewards, what are we going to eat?"

At a lakeside villa, a group of mermaids play and chat in the pool...

"Brother Yang, you're making money every day, you're already richer than a country, and you have so many sisters around you, don't you have any ideas?"

Chen Yang chuckled:

"Of course I have ideas... Let's keep making money!"

"However, money is hard to come by these days, so I'm planning to go out and earn some extra cash."

The beautiful King's ace spy, tears streaming down his face:

"Oh...shit!"

"You're making money, so why the hell are you messing with me???"
