One day, tickets fell into the hands of people across countless worlds. Following closely behind were a hyper-dimensional train that traversed these worlds. Boarding this train allowed one to travel through countless realms, witnessing their landscapes, meeting their people, learning their knowledge, and savoring their cuisine… and, because of this train, the fates of people in each world were altered. In the Detective Conan world, Gin became engrossed in training and made a deal with Conan; the former workaholic of the Black Organization ultimately became a pay thief. In the Naruto world, Jiraiya traveled freely through other worlds, broadening his horizons and writing the world-shaking "Make-Out Paradise," a quartet of mermaids, angels, elves, and succubi. In the Demon Slayer world, the Hashirama of the Demon Slayer Corps hung Muzan Kibutsuji upside down from a tree, chatting and laughing as they sipped wisteria tea, waiting for the sunrise. In the One Piece world… because of the arrival of the hyper-dimensional train, dimensions became interconnected, countless worlds became more prosperous.

Hao Meng, a 32-year-old internet cafe owner, becomes the lucky one chosen by the system.

Lu Xuan transmigrates to a high-martial arts world and activates the multiverse trading system!

As long as you keep trading with the myriad worlds, you can become stronger!

…

Lu Xuan smiled faintly: "Welcome to the City of Myriad Realms, where you can find everything you desire..."

And so, many years later.

The Emperor of the Ming Dynasty declared: "I am the true dragon! The Mad Death Camp, obey my command! Under heaven, all land belongs to the Emperor!"

Wang Yuyan: "Cousin, let's not contact each other anymore. I'm afraid Lu Xuan will misunderstand..."

Ferryman Zhao Li: "You're Hades Cha Cha, right? I'm really angry right now~"

Orochimaru: "Hehehe~ Uchiha Madara, do you also want to dance?"

Zhang Long, who was transported to another world by a large truck, had his soul split. The main soul awakened the talent of sharing space, which pulled other soul fragments into it, helping them recall their past life memories and awaken their talents.

Each Zhang Long character develops rapidly, and the plot doesn't drag.

Pirate Zhang Long: [Incarnation of the Devil] → [Representative of the Devil]

I am the representative of the devil, all things of the devil belong to me, and no power of the devil can harm me.

Naruto Zhang Long: [Balance of Yin and Yang] → [Mutual Generation and Mutual Restraint]

Based on the balance of Yin and Yang, I can also restrain your abilities!

Zhang Long (one person): [Comprehensive Development] → [Large Hexagon]

I have no weaknesses! I am invincible in my class!

Zhang Long, the God of Gaming: [The Curse of Knowledge] → [The Blind Spot of the Wise]

Huh? Isn't this something everyone knows?

(Within the current world)

Digital Zhang Long: [The Chosen Representative] → [The Messenger of Idealism]

Destiny is in my hands! Only I can wield the power of my will!

…

Currently available worlds include: Naruto, One Piece, Under One Person, Super God Academy, Digimon, Toriko, and Dragon Ball.

I awakened Su Hui, I awakened the shared space, and every talent I awakened is incredibly powerful.

Later, I became the Lord of Heaven's Dao. In this different world, I participated in the storyline and obtained the origin.

During this process, I gradually realized that my cheat ability was extraordinary, and that I seemed to have a special identity.

I am Zhang Long, a dragon from all the heavens and myriad realms.

I want everyone in the world to be like a dragon!

They transmigrated to a high-level martial arts world where spiritual energy was reviving and monsters roamed freely.

In his moment of confusion, Ye Xuan obtained a dimensional chat group that could communicate with all worlds.

Looking at the familiar big shots in the group, Ye Xuan fell into deep thought.

Tony Stark: "I'm going to die?"

Whitebeard: "My son is dead? Killed by my other son?"

Nagato Uzumaki: "I've been told I'm dead?"

All eyes were on Ye Xuan.

Ye Xuan: "What are you looking at? I'm not dead."

Waking up, he found himself reborn in the world of "Covering the Sky," becoming Ye Tiandi's Mercedes-Benz. Just as he sighed at the hardships of life, he encountered other versions of himself from countless worlds. Their power was completely shared, an endless accumulation of Rocks. A single Rock was not strong; multiple Rocks, their strength was uncertain. After sharing power, he became not only the true form of an imperial weapon in the "Covering the Sky" world, but also a cosmic overlord in Marvel, a supreme demon god in the abyss, the father of all gods on Mount Olympus, and the progenitor of the Dao in the primordial world. Even more so, an infinite god! Rock: Plans changed, sweeping across the heavens.

He Lang accidentally obtained the Adventure System of the Universe, and from then on gained the ability to travel through the universe.

From The Great Ruler, Tomb of the Gods, The Legend of the Great Desolate World, Primordial Desolation, Ever Night, and The Swordsman in the Snow, he journeyed through world after world, pursuing the true meaning of the Dao. (This is just a rough outline.)

There is no such thing as a peaceful life; it's just that someone is bearing the burden for you. Behind the scenes, where the light cannot illuminate, heroes are fighting bloody battles. [A List of the Top Ten Behind-the-Scenes Heroes of the Myriad Realms] No. 10 Demon Slayer Corps: We, the Demon Slayer Corps, will live forever until the day Demon Slayer dies. No. 9 Night Raid Team: We are all professional assassins. No. 8 Straw Hat Pirates: Nika and Luffy ignite the summer. No. 7 Dragon Slayer Lu Mingfei: We are all little monsters... No. 2 Emperor Ye: He quelled the turmoil, destroyed the forbidden zone, and suppressed all enemies in the world. No. 1 Desolate Emperor: A young man born in the Great Wilderness, destined for greatness, he reigns supreme for eternity. When the life of the Desolate Emperor is revealed, the myriad realms are shocked and moved to tears.

Shen Lang, carrying the "Divine Elephant Suppressing Prison Technique," transmigrated to the world of "Covering the Sky." Just as he was about to bring a small shock to the people of "Covering the Sky," he was suddenly pulled into a chat group. The chat group was full of himself. Shen Lang was dumbfounded. It turned out that he was not only the protagonist of a fanfiction with cheat codes, but also a transmigrator? Even more incredible, in each world, in addition to the chat group, he also had cheat codes. Shen Lang in "Swallowing the Stars": Borrowing the Martial God, borrowing the Fruit of the Future, obtaining the Great Success Method, enjoying the results first, and making up for the cultivation later... Shen Lang in "Battle Through the Heavens": Virtual space, simulated cultivation, becoming a top alchemist in one second, adding points to become a saint! ... Xiao Yan, Luo Feng, and Ye Fan were all dumbfounded: "Holy crap, there are cheat codes!" This chat group can also travel to the worlds of other group members? "Fanzi (Fengzi, Yanzi), bro will take you to a dungeon..." (Currently, the world is tentatively set as...)
