Di Xiu transmigrated, becoming a gray rat in another world. Not only must he build a protective dungeon to safeguard himself and his race, but he must also constantly guard against invasions from other races. Humans, gods, demons, monsters, dragons, elves, ancient taboos... even outworld gods coveting the world! The former order crumbles, and the apocalypse topples the towers of civilization. In the face of life and death, Di Xiu comprehends the truth of magic. Magic is not chanting, but a rigorous set of underlying world protocols! Only with the correct logical framework can it be safely compiled and run. While other mages are still struggling to chant spells with their flesh and blood, Di Xiu is already debugging magic circuits in the dungeon, developing the third-generation gray rat exoskeleton armor, heavy armored mechs, and aerospace carriers... The magical industrial age has begun! The gray rats are building a jungle of steel and gears. Mechanical rats wield precision...

(This story has a lot of funny and romantic slice-of-life moments in the early stages, and it's not just a pure wish-fulfillment story with constant showing off. You can read it if you think it's worth it.)

In the year 1485 of the Solar Calendar, a shocking scandal broke out in the Famia Empire—

That human genius scholar who improved the calculation formula, invented soul-sensing magic, and ended the elves' more than 100-year reign in the "Strongest Magic Brain" competition.

He doesn't know any magic at all; he's a complete low-magic user!

Reincarnated into another world, Owen became a useless young nobleman.

Despite lacking magical talent, he unexpectedly discovered that magical theory was quite easy to learn, even less difficult than calculus in his previous life.

"Perhaps I can change my fate through the exam?"

Thus, Owen rekindled his test-taking spirit and gradually emerged on the academic stage as an unconventional genius.

"Orc, so what if you're strong? Can you solve problems as fast as I can?"

"Elf, so what if you have a lot of magic? You'll still beat me on the exam first, won't you?"

"So-called genius is nothing more than one percent inspiration and ninety-nine percent perspiration."

At the graduation ceremony of Vilia College, outstanding graduate representative Owen delivered a passionate speech on stage:

"Even if I'm just a country bumpkin, I'm determined to go and snag a cabbage in the capital."

“Fira, Tomman, and Rice, who created the magic formula when he was 9 years old because he wanted to get out of school quickly—heroes are as numerous as fish in a river.”

"Please remember the name Owen."

"Because one day, I will, like my predecessors, make it resound throughout the world!"

"Tell me, what should I do if I'm ambushed by monsters in the dungeon?" "Fight them!" "Next question, what do you do when you face an evil lich that you can't defeat despite your best efforts?" "Will it devour corpses?" "It has no interest in your corpse; at most, it'll turn you into an undead." "Fight it!" "Fight it! All you know is fight! What if you die?!" "You'll be resurrected, and even stronger! Fight it!" Chen Luo, transported to a dungeon in another world, possessed the cheat ability to resurrect after death. If he could retrieve his dead body, he could be resurrected without damage and gain additional enhancements. Initially, even weak mushrooms could kill him, but gradually, dungeon monsters would turn away at the sight of this man; after dying countless times, terrifying legends of the undead spread throughout the dungeon, and he...

Five hundred million years ago, the Cambrian Ocean stretched to its boundless surface. Anomalocaris reigned supreme, trilobites swarmed, and life experienced an explosive explosion. At the same time, a primitive invertebrate opened its eyes, and the soul of a future human attached itself to its body. Bound to a biological editor, it evolved from a weak, tadpole-like larva step by step into the king of the Titans! Invertebrates, chordates, vertebrates, fish, amphibians, reptiles… Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian… enduring extinction frosts, gamma-ray bursts, supervolcanic eruptions, meteorite impacts… in the blink of an eye, oceans transformed into land, a mere blink of an eye turning billions of years. Five hundred million years later, the ultimate creature named Godzilla finally returned to its original era. But it discovered—countless prehistoric Titans awaited…

You must first hone your skills until they are as refined as Scáthach's; you must train your physique until it is as powerful as Typhon's; then, you must lift the sword left by the King of Britain, mount Pegasus given to you by Medusa, and set off for distant lands; along the way, you will breathe fire and unleash thunder; people will weave your name into songs and sing them, their voices trembling in the night. You will become a legend, a walking—Heroic Spirit. …“Becoming a Heroic Spirit only requires three steps: close the book, open the door, and then go out.” With these words, Shane, carrying the Book of Heroic Spirits that could summon countless legends and myths, arrived in the world of Fairy Tail. “Hmm, out in the world, let's slay a dragon first!” (PS: Even those unfamiliar with Fairy Tail and Type-Moon can easily read this; enjoy! QAQ)

Su Xiu transmigrated to the world of American comics, a world that blends Marvel and DC, where all sorts of villains emerge!

Terror gripped the land, but he remained completely calm!

Because he awakened the 'All-Heavens Invasion System', which allows him to randomly select natives of this world to conquer other worlds. The rewards obtained by the superheroes are amplified a hundredfold by Su Xiu!

Iron Man is infected with the T-virus and embarks on a glorious evolution of flesh and blood.

Thanos: Is this how peace can be achieved?

The Primal Beyonders: Warhammer Four Peddlers?

OAA: I see a higher power!

Soviet revisionists: You may make a small profit, but I will never lose!

Huh?

How did Spider-Man become Gwen Stacy? Scarlet Witch, what are you doing here? Flying Girl! ...

He closed his mind, forgot his name, stayed in a simple rented house, immersed in a virtual game, and finally died suddenly. Opening his eyes, he found himself traveling to the familiar Runeland and encountered a Darkin magic sword, so he was called Atuo. "You give me strength, I let you die." From then on, there was a figure carrying a magic sword on his back in Runeland.

(A story with multiple female protagonists is not a happy one, but the ending will be happy, and the protagonist is not extreme.) After traveling to Ionia, the timeline is still very early. The conflict between the two cities has not yet broken out, Noxus's plan to invade Ionia is still being prepared, and Sylas is still imprisoned in a dark dungeon. Faced with Shen, who is not as old-fashioned as he will be in the future, and Jie, who seems aloof, Lin Yu chooses to lead them to steal and rob. Of course, the most important thing is them. Sona: I just want a brother, I don't care about anything else. Xia: I can only feel at ease when I am with you. Irelia: Don't be like this, uh, don't let others find out. When Lin Yu was forced to leave Ionia and go to the entire Runeterra, he suddenly realized that he had unknowingly left so many concerns in Runeterra. Wait, who are you? Syndra: Energy outpouring! Lin Yu:! When did I provoke the ball girl? No, I have never seen Syndra!

Luo Yu travels to Runeterra, becoming Ryze's heir. He's tasked with gathering the world's runes. However, the true threat to this devastated world lies not in the runes themselves, but in the hearts of those twisted by them and fate... From the court intrigues of Demacia to the icy wars of the Freljord; from the neon shadows of Piltover to the spirits and warriors of Ionia... Luo Yu appears at every crucial plot point. He's Lux's trusted mentor, Jarvan IV's trusted strategist, and LeBlanc's hated troublemaker. Viego: "You're the twist, you've ruined all my plans!" Swain: "Luo Yu... who is he?" Luo Yu: "Don't ask. I'm just a passing bard whose hobby is saving the world and picking up runes."

Li Yu transmigrated to a dangerous fantasy world, but fortunately he had the golden finger that every transmigrator needs, and the golden finger was the legendary supreme qigong---Divine Elephant Suppressing Prison Force!

Using Qi to guide the spirit, and the spirit to form an image, every gesture and movement carries the power of a giant elephant. The human body is composed of 840 million particles. If its potential is awakened, every tiny particle is the power of a giant elephant. When all of them are awakened, they are comparable to a divine elephant, capable of overturning rivers and seas, roaring down stars, plucking the moon and swallowing the sun, all in the blink of an eye.

Elephants come in countless varieties and transformations. The giant elephant, as a child, transforms into the dragon elephant; the dragon elephant, in its green form, transforms into the primordial elephant; the primordial elephant, in its mature form, transforms into the divine elephant. This is the ultimate form.

With such extraordinary skills, only one problem remains for Li Yu!

That is... practice!
