Lin Ming has been in this world for sixteen years, always believing it to be an ordinary one. He copies novels, saves up small amounts of money, and dreams of a simple and happy life with female seniors on his left and female juniors on his right.

It wasn't until he stepped into Kuoh Academy and saw Toujou Koneko's cat ears, Himejima Akeno's lightning, and Rias's destructive magic... that he realized with despair that this was "High School DxD," a place where people could die! The aftershocks of the mystical powerhouses fighting could obliterate him.

In a moment of crisis, the Infinite Dimensional System awakens: Afraid to become stronger? Newbie quests force you to make extra-long confessions to three popular heroines! Too afraid to take risks? Then traverse countless worlds for forced training!

I've traveled through time, but not just one world. When awake, I'm in the world of Souman, and when I'm asleep, I'm in the world of Harry Potter. But that's not the most outrageous thing. What's outrageous is the restraining power of the Souman world: Gaia, who enjoys picking up random things in the World Sea. To prevent the daily Souman world from being destroyed, Hanyu Genichi reluctantly picks up his wand and cleans up Gaia's mess. From the T-virus to Kabane, to ghouls, gastrula, and later, giants, they don't care about the lives of humans at all, do they? Gaia, you really only think about yourself.

Muchen traveled to the world of daily anime and lived there for seventeen years. During these years, he had been working hard to get married. But he found that since the world's first virtual game was released, the world seemed to have become wrong. Then...

[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.

Bound to an improperly trained "simp" system, charm increased tenfold! First, a small goal: dominate all the beautiful girls in school...including teachers and the principal! Huh? They're all so proactive! Kasumigaoka Utaha: Can we have a dating simulation? (For research for my new book.) Li Kong: Lots of people ask me out, remember to book in advance next time! Himuro Ayame: Are you free for dinner tonight? Li Kong: Yes, but I never pay for dates with beautiful girls. Himuro Ayame: Then I'll treat you. Ellie: The girl you were having dinner with last night, the one you were being intimate with, looks a bit like my sister? Li Kong: She's your sister. If you have a problem with that, let's break up! Ellie: It's okay, I can't live without you. Ayase Saki: Was that a girl you were talking to on the phone just now? Li Kong: She's your mother. She asked me to go to a hotel tonight. ...Hayasaka Ai: A maid who doesn't want to be the mistress isn't a good maid! Kitagawa Kaimu: If I win this battle, you have to go out with me! Kirisu Mafuyu: I haven't handed in my homework yet! Toyokawa Shoko: You've taken all my teammates... Saionji Sekai: Mom's shoes are here too, and this voice is... (Male/Female, all virgins accepted)

Bai Chengfeng transmigrated to a world of everyday anime and manga, acquiring the [Doujinshi Artist] system. By continuously drawing doujinshi, he could extract various overpowered abilities. He created a series of works including the [Time Stop Series], [Xx Modulation Mode], and [Tentacle Summoning Xx]. He initially thought he would spend exciting and thrilling days in this everyday world. However, he didn't expect to be pulled into a place called the Multiverse Chat Group. ... Izumi Sagiri: "Onii-chan is the best person!" Kocho Shinobu: "Time stop? How can there be such an illogical ability?" Black Tower: "...Why are all your abilities so abnormal?!" Lucy: "Uh, are you sure this is called overthrowing Night City? How come everyone thinks you're their friend? What, you say it's hypnosis? That's too exaggerated!"

[Starting with Chronos + Kamen Rider + Crossover Anime + Tanzaburo Higashijima + Nisekoi + Multiple Heroines]

Transmigrating to various anime worlds, Shi Wushuang begins as Kamen Rider Chronos. In the realm of the God of Time, day and night are but a thought away, and time stops and flows backwards only for him.

On campus, Shi Wushuang is a gentle, cheerful, and sunny male god, but when facing strange people, he is a cold-blooded judge and a grim reaper.

The city's impurities, the Amazon lurking in the shadows, the constellation apostles on campus, the Shocker monster causing chaos, and monsters from other knight worldviews in the dimensional rift, and the BOSS.

When he is Kamen Rider Chronos, he puts his index finger to his lips and says, "Shh, during the trial, the scene must remain serious."

When he was Kamen Rider Eternal, he gave a thumbs-down sign and said, "When you get to hell, just say my name, Shinigami, and you can skip the toll."

When he is in Kamen Rider Evol Black Hole form, his right hand spins like a black hole: "This day next year will be your death anniversary, Ciao."

When he was the Blade of the God of War, he pressed his thumb down on his index finger and said, "Don't misunderstand, I just want to kill you all, or be killed by you all."

When he is Oma Zi-O: "If you do not bow to the king, you have already lost your true destiny. Your name is on the Reincarnation Stele. Bow with each step. If you are devout and sincere, your sins will be halved on the road to rebirth."

All sorts of weirdos: What? I'm taking on the Knight Boss one-on-one?

...

The tentative list of female leads includes: Elisa who speaks Russian from time to time, Shiina Mahiru, the angelic neighbor, Okada Yuriko, the eccentric Takumi, Kirisaki Chitoge, Kato Megumi, and Kasumigaoka Utaha, the black-stocking fanatic.

Elves, dwarves, halflings? Where does this come from?

Mage, priest, paladin? Supernatural powers? Interesting...

Spellcasting talent detected? Does that mean I can become a noble mage?

"No, buddy, what do you mean by assigned to the Geotechnical and Natural Sciences School?"

"Damn it! How come I'm assigned to civil engineering after arriving in another world?"

…

"Master Mage Gerudo, what do you think of the famous and legendary graduate of your magic academy?"

Many years later, when faced with an interview, the elderly magician remained silent for a long time.

"Nothing with a mage's soul!"

[A clingy class monitor, a domineering yet weak and possessive older sister, an extremely possessive heiress from a wealthy family, twins with level one autism, and no system]

Chen Yue is reborn on the sofa in the home of the school beauty and class monitor.

The widowed school beauty's mother walked out of her room without any warning.

Even though it was the second time he had seen it, Chen Yue was still dumbfounded.

Their eyes met...

The school beauty's mom is a beautiful and gentle mother-in-law! She can manage the company's finances and also soothe people's hearts.

My older sister and I grew up together. She has fair skin, a perfect figure, and her doting affection for me is evident in every word.

The clingy school beauty and class monitor, the domineering yet doting older sister, the extremely proud contract female capitalist, the highly talented and all-around great assistant, and the twin sister with level one autism are all his capable assistants.

But when it comes to stabilizing morale, it still comes down to women…

In his previous life, Zhang Beixing died young due to health reasons, but was reborn back to his college days.

Looking at this young, healthy but weak body, he decided to exercise hard and strengthen his body starting today.

[Question: I want to improve my physique and become stronger. What should I do?]

Zhang Beixing went online for help, and the system happened to appear. As long as he listened to advice and completed other people's suggestions, he could gain ability points and become infinitely stronger.

"Running slowly? Then carry some weights! Carrying 50 kilograms of weight and running ten kilometers every day will definitely make you as light as a swallow."

"Lack of jumping ability? That's because you didn't step your left foot on your right foot. If you train like this, you can fly..."

"Want to learn some weapons for self-defense? Come on, who touches controlled knives these days? Just practice chopping tree stumps with a wooden sword. Swing the sword ten thousand times a day, and when you've mastered it, you can injure people with your sword energy."

"Want to learn some kung fu? Who still practices traditional self-defense these days? Times have changed! Why not try to deduce the 'Flowing Water Shattering Rock Palm' and the 'Origin of Qi Body'..."

“…”

As one outrageous suggestion after another was put forward by stupid netizens.

Several years later, Zhang Beixing was interviewed and asked how he became a 'superman'.

He smiled slightly: "Nothing, I just listen to advice"

Netizen: "??? We are just joking, are you serious?"
