Yuro transmigrates to the world of One Piece and becomes bound to a super check-in system.

You start by obtaining a physique enhancement pill and a Logia-type Devil Fruit.

Yuro broke into Beehive Island, gained Rocks' approval, and won the praise of Whitebeard and Shiki, eventually joining the Rocks Pirates.

From then on, the Rocks Pirates gained a new strongest fighter, possessing the strongest physical skills, the strongest Devil Fruit, the strongest swordsmanship, and the strongest Haki.

Rocks: Yuro, I call you the strongest!

Whitebeard: The strongest man in the world? That's that guy's exclusive title!

Roger: I am not as good as Yuro, he is the true king!

Garp: I'm tough enough, but he's even tougher than me!?

A soul from another world arrives in the world of the Lord of Mysteries, but he's transported to the wrong place—the moon… PS: Two male protagonists [Klein and the main character], no female lead, the protagonist's mother is a fallen goddess, he arrives via a portal to the moon, he has built-in cheat codes, is in a state of chaotic neutrality, suffers from schizophrenia, and is a hypocrite. The main character's personality is similar to early versions of Nvidia, treating the world as a virtual game and characters as NPCs, perceiving the world's good and bad qualities from his own perspective.

Because of the overlap of parallel universes, countless worlds equal to them are about to collide! To secure the final right to survival, each Blue Star will send two representatives to the Forbidden Land of the Gods to determine the last survivor! Jiang Li, who has played the role of the Rock King Emperor for 3,700 years, enters the Forbidden Land of the Gods to fulfill his final contract. Upon seeing this retired old man's nonchalant attitude, the entire population of Blue Star Seven is stunned! At this moment, the ferocious beasts of the Gods descend! Countless contestants are killed or wounded! People witness the destruction of other planets! They silently mourn their own final moments! But then they hear… “This world's demons…”

Having transmigrated to a world of advanced martial arts, Lin Ye only wanted to peacefully study at a martial arts university.

But that thing that calls itself the "Strongest Dungeon Boss System" seems to be a bit dim-witted.

It really thought Lin Ye was just a low-level cannon fodder boss!

Other people's skill tree is: Basic Fist Techniques → Fierce Tiger Fist → Ascending Dragon Fist.

Lin Ye's skill tree is:

Phase 1: [Normal Attack LV1], [Thick Skin LV1], [Charged Slam LV1]

Phase 2: [Berserk LV1], [War Stomp LV1], [Cleave LV1]

Phase 3: [Summon Minions LV1], [Intimidating Roar LV1], [Thorn Aura LV1]

...

Final Stages: [Universal Apocalypse LV99], [Doomsday Judgment LV99], [Absolute Territory LV99], [Undying Grip LV99]...

Lin Ye repeatedly emphasized that he had transmigrated to a high-level martial arts world, and that he was a human!

No, you're a goblin!

[Please abandon your illusions and prepare for battle!]

[This system will definitely make the host the strongest BOSS in this world, and will never be defeated by adventurers!]

Several years later.

When all races invaded, the demon god grinned and twisted Lin Ye's head off.

But to their astonishment, they discovered that this appeared to be only the first vial of blood from the human before them.

"Congratulations, you've removed my limiter. Next up is Phase Two!"

While transmigrating into Douluo Continent and awakening the Dragon God Martial Soul, he only wanted to quietly become a god. However, no one expected that his inner thoughts would be overheard by Qian Renxue and others, and thus, the situation completely changed. ... Li Qing: This is the Pope of the Spirit Hall, the first empress of the future Spirit Empire. She's really beautiful; it's a good thing Qian Xunji got her. Bibi Dong: ??? ... Li Qing: This Ah Yin is unbelievable. She was completely fooled by Tang Hao. Didn't she ever think about why the Spirit Hall was able to arrive so quickly and find her so accurately? Also, your real son is already dead; this one is just a spirit from another world.

We've traveled through time, and we're still in the same world.

Bad news, abilities can't be shared.

Good news, most of the people we traveled through are well-known figures, and they're all scientists with incredible research and development capabilities.

But why are most of them villains?

(Naruto's Orochimaru, Ultraman Masaki Keigo, Under One Person's Avatar, Marvel's Harry Osborn, Kamen Rider Dai Shocker, EVA, Robosuit, Infinite Terror, Stone Age, The Three-Body Problem, The Wandering Earth, Gundam...)

In short, it's a story about these tech-savvy characters traveling through time together, and a group of scientists using cutting-edge technology to change the world.

Playing the search for people nearby, the future self called over and gave Lu Fan a chance to get rich.

Lu Fan gathered 6 million and entered the international foreign exchange market.

But he didn't have money to buy a bag for his girlfriend, so Lu Fan had to borrow some money from his friends first.

"A Feng, my buddy is short of money, lend me 20,000 yuan first!"

"Lu Fan, are you bankrupt? No!"

"Just tell me, will you lend me 20,000 yuan?"

"Sorry, brother Fan, only 1,000... No, no, no, I didn't know you were bankrupt!"

"Lu Fan, you're bankrupt and you're hiding it from me! Break up!

"I'm not bankrupt, let's break up..."

Ding... Ding...

"Friends, Lu Fan is bankrupt and is borrowing money everywhere, everyone be alert, don't be cheated!"

"Oh my god, I also received a message from him asking for money, just about to transfer 200 to him, almost fed the dog!"

See the message in the company group.

Lu Fan: "I'm really not bankrupt!"

"! ! ! ! ! ! "

A series of exclamation marks came over.

Lu Fan was kicked out of the company group!

Damn! I'm really not bankrupt, I'm going to be a billionaire soon!

My mobile phone is connected to the future, even if I go bankrupt, what's the problem!

[Farming + Village + Hegemony + Violent Joy + Military Generals + No Revenge Left Behind]

"Fengzi, do you want a wife?"

"Wife? Village chief, I want her!"

"If you want, join the army! Follow the rebels! Give them wives and food!"

"Okay, village chief!"

......

Three years later.

"The emperor of the new dynasty returns home in glory? Passing by our Zhaojia Village?"

"Hey! Fengzi...are you done with the battle?"

"No... No, oh my god! Meet His Majesty the Emperor!"

......

The introduction is weak, please read the main text!
