While other immortals were still fighting tooth and nail for an ancient magic weapon, project manager Li Yun had already signed a KPI-based betting agreement with "Heavenly Dao".

Upon transmigrating to the Immortal Realm, Li Yun discovered that this so-called eternal and immortal cultivation paradise was already terminally ill: monopolized spiritual veins, traffic congestion, information isolation, and rampant infighting. Ascension? It was merely another place to continue struggling at the bottom.

So he unleashed the ultimate weapon of the modern world—project management, capital operation, and large-scale infrastructure.

From the "Flying Sword Traffic Control System" that revolutionized transportation in the lower realms to the "Mobile Payment" that triggered a financial revolution; from the "Immortal Realm Engineering Academy" that broke the monopoly of knowledge to the "Interdimensional Trade Platform" that connects all realms... the "Immortal Realm Development Group" has planted its flag in every corner.

However, as the group's territory reached the edge of the universe, Li Yun discovered that the greatest crisis was not an external enemy. The backlash from the old Heavenly Dao, the accumulated karmic debts, the ideological differences among his partners, and the cold truth behind the system were pushing him toward a "Battle of the Dao Ancestors" that would determine the survival of all civilizations.

This is not just about cultivating immortality; it's an ultimate merger and acquisition of the ancient universe using thought, systems, and technology.

This is a legend that completely "formatted" the old immortal realm and personally rewrote the rules for countless universes.

Transmigrating to another world, while other adventurers followed the ancient strategy of "warrior tanks, mage deals damage, priest heals," Renn discovered that he could obtain the core talent of every monster he killed, leading to a complete absurdity: the berserker's [Blood Frenzy], honed over ten years, was obtained by slaying a single goblin. The mage's prized [Fireball] was merely a generous donation from a mutated shaman. After slaying the Goblin King, he accidentally acquired the [King's Aura]. By swiping goblins, Renn successfully transformed himself into a well-rounded warrior. Until one day, the Demon King's army besieged the fortress, and the heroes trembled in fear. Amidst the despairing gazes of the crowd, Renn silently pulled out a manual that lit up all the monster icons. "Don't panic." "I'll go to their lair behind the camp and get some magic immunity..."

In the past, I was surprised that the protagonists in the anime couldn't recognize them after traveling through time. They explained that it was because the two-dimensional characters were different after becoming three-dimensional. But after traveling through time, I want to loudly declare that the two-dimensional world is truly two-dimensional. The sky is blue, the clouds are white, and the grass is green. But as long as the color tone is slightly adjusted, everything in this world looks super two-dimensional! And I am no ordinary person after traveling through this two-dimensional world because I have a built-in point-adding system. Do you understand what I mean? With my supreme wisdom and my endless talent,

Traveling through the world of souman anime and signing a contract with CC, Hayami Yuu gained the Geass ability known as Perfect Copy. With a single blink, he can replicate the abilities of others. Okay, okay, the rest is easy. Copy all their abilities: Kageka Suigetsu, Ryujin Jakka, Sun Breathing... But then again, why is there suddenly a fox girl in a black JK uniform in the house? Her face is pale and she doesn't look well. Maybe I should give her some mana first? P.S. (For the harem, I'm targeting all the heroines and supporting characters, with priority given to Yuyuko, Isayama Yomi, Koyuko, Kiritani Suguha, Kikyo, and so on...)

Initially, Yun Chen thought he had transmigrated to a parallel world. But upon seeing the eleven enormous magic circles beneath the iceberg and the connection of his cheat-like abilities, he realized he had transmigrated to a still-developing material plane within the Panlong Magic Universe. Thus, before the divine plane fully connected to Earth, Yun Chen began his plans. The world's only magician, the world's only holy realm. Until he became a god, until he reached the Great Perfection, until the divine plane received its overseers… "So, where should I get a main godhood?"

This is the story of a girl who can connect to other worlds through dreams. Lelouch: You tequila girl over there, don't come over here! Ashina Isshin: This UMP45, Wolves will definitely like it... Goblin Slayer: That Gundam you mentioned over there, can it be used against goblins? Through constant contact and travel through the people in dreams, the girl gradually grows within them. Amane: Huh? Growth? What's that? Is it edible? Just being cool is enough! This is a record of a divine girl's observations of the human world. It doesn't matter if you haven't read much of the original story; each world is a super-expansion based on its own setting. While each world shares common principles and basic rules, there are rarely any mixed rules. Ghost in the Shell → Highschool of the Dead → Miko (formerly) → Ghost in the Shell → Black Magic → Infinite Storatos (IS) (in progress) → JoJo Battle Trend → Macross Frontier → Gundam SEED → ??? Currently involved: Ghost in the Shell, Miko the Blade, Code Geass: Lelouch of the Rebellion, Sekiro, Rozen Maiden, Honkai Impact 3rd, Type-Moon Fate, and Gundam series.
