What to do when you're out at sea without a ship? Allen: "Steal someone else's." What to do when there's no one on board? Allen: "Dig someone else's." What to do when there are people but no supplies? Allen: "Rob a warship." Treasure, famous swords, Devil Fruits, where do the women come from? Allen: "Brothers, look! There's a transport ship that's practically floating on air, it has everything!"... Transmigrating to the world of One Piece, relying on Baki's cheat abilities to rise to power in the East Blue, starting with just his fists, he steals everything—people and ships.

Yu Cheng transmigrated into the body of the young patriarch of the Whirlpool Clan. Faced with the impending extermination of his clan, he dared not stop for a moment!

Fortunately, his three adopted sons were transported to the worlds of One Piece, Demon Slayer, and Martial Soul, respectively.

And so—

"Old Cheng! Is the Dark-Dark Fruit any good? Hehe... I want to use the Impure World Reincarnation~"

"Come here! Old Cheng, I'm now an Imperial Beast. Which soul beast do you want as your summoning beast? I'll teleport you there!"

"Uchiha Madara wants to fight you? And the Otsutsuki want to join the fray?! Fine, let's fight!! Behold my Sun Breathing!!!"

——————

Several years later.

Uzumaki Yu Cheng transformed into the Demon King, wielding the Supreme Great Sword, stepping on the Black Dragon Emperor, his Rinnegan lowered, looking down at the dying Allied Shinobi Forces.

"From this day forward, the ninja world will be unified. And I... will stand high in the heavens, becoming an immortal god!"

(Just for fun, don't criticize if you don't agree) Li Chang'an is the most steadfast cultivator in the world of immortal cultivation. His lifelong pursuit is to achieve immortality through seclusion, never causing any trouble. However, he's struck by a multi-dimensional live broadcast system, forcing him to demonstrate his power to countless dimensions. Fearful of death, he's forced to replace his live broadcasts with the most basic cultivation knowledge. He explains "Basic Breathing Techniques," demonstrates "One Hundred Ways to Draw a Cleansing Talisman," shares "One Hundred Tips for Avoiding Danger"... He simply wants to appease the system, collect his rewards, and continue to hide. Little does he know that what he considers mundane basics are, to the powerful in other worlds, supreme secrets that lead directly to the Great Dao! The talismans he casually draws are revered as divine scrolls in the magical world; the breathing techniques he teaches sanctify the body of a wasteland youth; and the avoidance techniques he teaches are revered as the highest tactical guide by the interstellar fleet. Unknowingly, countless geniuses and powerful figures from countless dimensions have become his devoted followers, constantly breaking through by "imagining" his every word. When Li Changan was finally forced to leave the mountain gate, he discovered that... The mighty swordsman in front of him was actually the top player in his live broadcast room; the Lich King who commanded the undead army behind him was actually his class representative; even the old man selling candied haws on the roadside ascended to heaven by listening to his lectures! Li Changan: "I said all this was a misunderstanding, do you believe it?" This is a story about a "strongest master" who desperately wants to be low-key, but is always imagined to be invincible by his disciples.

Meng Mo traveled through the wilderness and became a nightmare demon in the demon camp. Unexpectedly, as soon as he transformed, he was dragged into the catastrophe by Luohou. In order to avoid becoming the ash of the battle between Taoism and demons, he took every step carefully and calculated everywhere, tricking Luohou, fighting Hongjun, destroying the Heavenly Palace, and breaking into the underworld... Unknowingly, he has become a legend passed down by the world. When he ascended to the Heavenly Palace, all the immortals bowed their heads; when he entered the underworld, all the ghosts crawled on their backs. He stayed in the Nuwa Palace and watched Nuwa dancing drunkenly; he climbed Kunlun Mountain and discussed Taoism with the Three Pure Ones; he stepped on Mount Xumi and laughed at the Buddha's cowardice...

How would Chang Wei, who doesn't know martial arts, make a living after traveling back to ancient times?

As a low-ranking servant in a brothel, the first thing to do when triggering the system is to summon the Thunder Commandos!

All fear comes from lack of firepower!

Could a team of special forces walk around freely in ancient times?

On an ordinary morning, Kevin coser just stepped out of the house when his vision went dark. When he woke up again...

System: Congratulations, you have traveled through time.

Kevin coser:...Ah?

System: And your cosplay came true, and you became Kevin.

Kevin coser: cool～

System: The good news is that you didn’t travel to the Honkai Impact 3rd world.

Kevin coser: What about the bad news?

System: You can't go back to your original world. So...

Kevin coser:?

System: Come save the world with me!

Kevin coser: This is too sloppy!

All in all, it’s a story about a hapless kid who saves the world after his cosplay comes true.

Pre-view reminder:

1. The person cosplaying is not Kevin himself, and I have never played Honkai Impact 3rd. My understanding of Kevin comes from Bilibili. Please forgive me for the imprecise settings.

2. Character ooc warning!

3. A self-inflicted work, Kevin COSER travels through time and space to curse back + Wen Ye + tutor, not involving Honkai Impact 3rd.

After a car accident, Xiao Tianci unexpectedly activates a multiverse travel system that grants him access to countless realms across the cosmos. The system declares: “诸天万界终将臣服在我的脚下”—the myriad worlds shall bow before him.

Using the system, he jumps into various worlds—martial arts realms, alternate dimensions, sci-fi settings—and completes tasks to gain rewards, cultivation abilities, treasures, or territory. He steadily builds cult power, founds sects, masters divine physiques, trains disciples, and expands influence. The tone is bold and decisive: no romance, no harem, and the protagonist is pragmatic, powerful, and far from a “saint.”
