[Multiple worlds + collector's mentality + base building + female protagonist (non-human) + late-game troop buildup + system that's just going through the motions]

Ostro, a transmigrator, looked around and thought he had been reborn into a high-tech era, until he discovered Terra, Eldar, the Martian technological world, and the intelligent legions in his memories, and then he burst into tears.

Good news, we're in the Golden Age (dark technology); bad news, the Iron Man rebellion hasn't happened yet; good news, my parents in this body have some assets on Mars; bad news, they're both dead and I just cried myself to death.

Until the system delivered the gift pack, making me feel invincible with the cheat, and then the system, having delivered the gift, simply left.

At least it gave Ostro some hope, didn't it?

then:

Cult of Mechanics: How does he always manage to retrieve the complete STC template? He must be a Chosen One of Ohm Messiah.

Primal: A powerful, loyal, and resource-rich sage. We should try to get along with him. He has no other flaws except that he sometimes likes to steal the power armor from his minions.

All Astartes: Do you still want the power armor I just DIYed? You promised to trade it for 10 Terminators, can you still do that?

Tarasin: You're stealing my loot! Fine, you took my spoils, but how did they end up in my house?

(This is a new book by a new author, please forgive any shortcomings!)

[Synopsis]

When Chen Mo, a corporate slave, died from overwork, she woke up as the Black Tower in the game "Collapse Iron," bound to the Multiverse Puppet System. So, in the cultivation world, she used scientific principles to refine pills; in the city, she used magic scrolls to speculate on stocks; and in the magical world, she used cultivation formations to mass-produce scrolls. While powerful figures from three worlds went crazy for her "ancient inheritance," she sat in her safe house, watching her three clones causing trouble on the screen simultaneously, and chuckled: "A civilization of one? No, now it's us."

A viral outbreak swept the globe, cities fell, and once-prosperous cities became zombie-infested infernos. Lin Chen, on the verge of despair, unexpectedly awakened the Red Alert system, gaining initial power enough to sustain his hope of survival from the start—an Allied base vehicle, well-equipped American soldiers, a powerful Grizzly tank, and the first funds to activate his base.

In this perilous post-apocalyptic world, he is no longer alone. The precise fire of American soldiers forms the first line of defense, the tracks of Grizzly tanks crush the corpses of zombies, and the massive Allied base vehicle is the foundation upon which he rebuilds order and fights against the apocalypse. Lin Chen must rely on the system to continuously expand his base, unlock stronger units and technologies, and, amidst the siege of zombies and the suspicion of survivors, use steel and artillery to tear a path to tomorrow for himself and those around him.

Robin was given a chance to travel to the world of Game of Thrones.

Fortunately, he became an immortal demi-human.

Unfortunately, he was targeted by an evil god named Slaanesh.

[Male transmigration; the small worlds may or may not have a romantic pairing]

1. The son of the cannon fodder crown princess (√)

According to historical records, Prince Mengzhang was exceptionally intelligent from a young age. He was literate at the age of three, skilled in martial arts at the age of five, and was made crown prince at the age of nine.

He ascended the throne at the young age of fifteen. He was well-versed in historical materials and had lofty ambitions.

During his time in power, he implemented the county system, opened free schools, and established orphanages and nursing homes.

He was brave and skilled in battle, defeating the Xiongnu and killing the Tartars.

During his reign, the country was at peace, and the people lived in contentment.

But initially, he was just the son of a supporting female character.

2. Sons of educated youth in the control group (updating)

I heard my mom is jealous of other people's good lives?

I heard my mom envies other people's sons for being smart and good at studying?

No, no, no, don't be jealous, because your perfect son has arrived!

"Father, I want to resign! What? If I resign again, you'll have to pass the throne to me? Don't be ridiculous, I'm still young! I won't resign, okay?"

"Qingque, how have you been to your brother? Do you want to be the crown prince? It's free, hey... don't go, don't go, I'll give you money, okay? The price is negotiable!"

"Child, do you want some Wangzai? If you were the crown prince, you could have as much Wangzai as you wanted, how about that? What's a crown prince? You can't eat or not eat? You little brat, do you want to stop having snacks?"

Li Chengqian was speechless. He just wanted to be a nobody who could live a carefree life and do nothing!

But with his strength, he couldn't allow it!

As the Crown Prince of the Tang Dynasty, while others were focused on intrigue and power struggles, always ready to launch an attack, he was constantly thinking about resigning.

While others feared being exiled to the frontier from Chang'an, he tried every possible way to escape the city.

He did everything from writing novels and running brothels to establishing schools, defeating the Tartars, promoting national prestige, and protecting the country—anything that had nothing to do with the Crown Prince.

What? You want me to oversee the country? You're dreaming! I won't do it!

He recklessly courts death, yet remains alive and well; he resigns every day, but his position remains secure!

But what can we do about it...?

He could only look up to the sky and sigh, "Who can save me? I really don't want to be the crown prince!"

A game called "God's Crown" suddenly appeared.

One hundred million players will be randomly selected from around the world to enter the game. The first batch of players will be elected as lords and given territories, and will draw corresponding lord talents.

You can then invite others to join the game and become your subjects.

Resources from the real world cannot be brought into the [Divine Crown], but resources from the [Divine Crown] world can be extracted into the real world...

The water from the Moon Well that makes one young again, crystals with mysterious powers, legendary magic...

When all the lords returned after the beginner period, the world was shocked, and the lords became the new top echelon of society...

…………

In his past life, Chen Luo obtained the A-level talent [Dawn], making him a top-tier player even if not a major player. However, because he chose the wrong side, his territory was confiscated, and he died in despair.

If given a second chance, Chen Luo decided not to get involved in the vortex so easily, and to watch the dogs fight from the sidelines.

But why was the way it was opened wrong from the start?

[Ding! Congratulations, player, you have drawn an SSS-level skill – Demon God!]

"Uh, isn't this the talent of that great demon king who was besieged and killed in the early to mid-stages of my previous life?"

"What? Choosing the Demon race grants extra bonuses? Automatically changing to the hidden class Demon King?"

"System, select the Undead race..."

————————————————————

First of all, this is a novel about accumulating troops and fighting for supremacy, and I don't know why Tomato doesn't have a "fighting for supremacy" category.

Secondly, this isn't a cowardly character like Gou Daowen. The protagonist isn't actually weak; he's a late-game powerhouse with stacked buffs, focusing on stable early-game development and leveling up to build his empire. He forms alliances when necessary and yields when necessary—accumulating resources and delaying his demise.

There are no divine generals or poisonous warriors in the book. Don't ask, it's just annoying to read...

The protagonist, Lin Yan, is a modern-day engineering PhD proficient in mechanical engineering, materials science, and social management, as well as a survivalist. He transmigrates into the body of a useless, exiled noble young master in another world. His cheat ability isn't combat magic, but rather near-absolute "logical modeling" and "material analysis" abilities, allowing him to quickly understand and optimize the technology of this world.

This is an alternate world where magic (elemental power) and martial arts coexist, but the social structure, production technology, and ideology are relatively backward. Magic and martial arts are toys for the privileged class, while the common people live in poverty.

The protagonist does not pursue the ultimate in personal martial arts prowess, but instead uses modern knowledge to launch a sweeping "industrial revolution" and "social transformation" from scratch. He uses the power of technology, systems, and ideas to fight against the corrupt aristocracy, the mysterious magician class, and the powerful martial arts sects, ultimately reshaping the entire world order.
