Huangfu Longdou, capable of traversing countless worlds, relies on a side-effect transfer system to continuously travel and level up. He experiences various worlds: the technological muscle-building abilities of the Kengan world, the spider-like powers causing the death of loved ones, the Green Goblin serum's second personality, the technological serums of Shaolin Soccer, the internal energy conflicts of the Star Absorbing Technique, the internal organ damage of the Seven Injury Fist, the disfigurement and poisoning of the Thousand Spider Poison Hand, the Star Absorbing and body explosion of the Amazing Couple, the Shennong Sect's poisons of The Great Laughing Jianghu, the Crimson Fire Divine Skill of the Storm Riders world, the Lizard Serum of The Amazing Spider-Man, the Devil Fruits of the One Piece world, the God Genes of the Corpse Brother world, the Pure Dharma of Mount Shu, the Fenji Sword with its malevolent energy, the monster cells of the One-Punch Man world, and the Iron Man world...

It seems things started to change around 2014. Lee Soo-man glanced at the company's artist list and cursed. Park Jin-young checked his rabbit and breathed a sigh of relief. Yang Juhua? Yang Juhua is gone! Bang Si-hyuk is still that fat guy. Lin Youtian: Kim Tae-yeon, why are you running? Kim Tae-yeon didn't turn around, covered her ears, and took off with her short legs. Lin Youtian: Bae Joo-hyun! What are you doing? Bae Joo-hyun silently put away the scissors in her hand and smiled brightly and generously. Lin Youtian: Zhang Wei! What did you say? Zhang Wei spread her hands, speechless. Zhang Yuan-ying was about to speak when Liu Zhi-min grabbed her and pulled her behind her: "You have to queue!"

Bai Ju hadn't considered becoming an idol, but after thinking about his own situation: he could sing and dance, was physically fit, slept little, wasn't afraid of the cold, had plenty of energy, was handsome, could plagiarize songs, and was based on a peninsula—wasn't he a chosen one? Since he was already here, he might as well give it a try. [Multiple female leads, no system, career and romance are evenly balanced, mainly focusing on daily life.]

Why do you speak without any inflection?

...

"Why are your bangs so long? I can't even see your eyes."

...

"Can't you be a little smarter? Don't believe everything I say!"

Shen Yuerou finally reacted and raised her head.

"Can't."

"So, do you like me?"

"like."

Shen Yuerou's voice remained calm and indifferent, but the person in front of her was going crazy!

I've been transported to the beginner village, Sirius Island, and the beginner's gift pack contains the Fire Dragon Slayer Magic.

In order to avoid becoming a dragon soul under the Black Dragon King's claws, Luo Xia chose to stay put and cultivate, waiting for the Fairy Tail main characters to arrive.

Ten years later, the dragon arrived, not a black dragon but a blue dragon... Kaido the Blue Dragon.

Luo Xia: I've been practicing Dragon Slayer Magic for ten years, preparing to join Fairy Tail as an S-Class Mage, and you're telling me this is One Piece?!

Kaido: What kind of monster did I recruit? What kind of subordinate dreams of slaying dragons all day long?!

Yan Zaijin: Actually, Luo Xia is pretty good, provided that the bastard didn't use me to farm money with the World Government, 100 million each time, and didn't even share it with me.

Art Disaster Queen: That son of a bitch, Loscha, is really wicked. He's treating me like a lowly samurai.

Brother Disaster Jack: Luo Xia's daily routine consists of eating, sleeping, and beating up his younger brother. You ask who his younger brother is? Don't ask, I just don't know.

Heavenly Dragon, Thunder Dragon, Iron Dragon, Shadow Dragon, Light Dragon, Sword Saint Dragon, Azure Dragon... All dragon-slaying magics are now under my control, making me the strongest dragon.

Rescue a lost girl and reap real-world rewards. Different scripts, different roles, different circumstances. In the game "Rescue," I teach the princess of a Japanese conglomerate Eastern knowledge, turning her into the queen of the conglomerate; I teach the holy maiden of the demonic sect Chinese immortal arts, turning her into the leader of the righteous sect; but that world-destroying dragon girl loves the ordinary and insists on dragging me to live a secluded life in the countryside, a pastoral idyll. Sorry. Game over, I'm leaving first! ... "Jiang Ya, have you seen our Japanese teacher? She's so stylish, I heard she's the heiress of a conglomerate!" "Jiang Ya, shouldn't we go meet our new counselor? That ascetic face, she's like a fairy from a cultivation novel!" "Jiang Ya..." Jiang Ya sighed, asking, "Who's here again?" "They're all here! Downstairs in our dorm... Hey, look! They look like they're about to fight!" In university, ...
