[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?

A parallel world, invaded by the Abyss, has created countless dimensional worlds. Everyone over eighteen can awaken dimensional abilities as a talent. Ye Changge transmigrates here and discovers that these dimensional worlds are actually familiar anime and movies… Relying on his familiarity with the plot, Ye Changge chooses the Hogyoku as his talent. What? Naruto only has cataracts and red-eye disease? The Tenseigan and Rinnegan will crush anyone who disagrees. What? The Four Emperors are just a joke? Shanks is missing an arm, and Whitebeard is old and frail, so they're not in danger? They obviously haven't suffered any beatings in the new world. What? The strongest and safest place in the Gotei 13 is the 5th Division? Are you kidding me because Aizen didn't use hair gel? … Looking at the information this world has about the dimensional worlds, Ye Changge is speechless. Since that's the case, then let me rule this world and crush the Abyss! This novel and its characters are purely fictional. Any resemblance to actual persons, living or dead, is purely coincidental.

Just when I was giving up and waiting to die, the system told me that I had memories of my past life and a [troop production system]!

Suspicion from Konoha's higher-ups? Danzo Shimura's conspiracy? Itachi Uchiha's executioner's blade? No! This so-called "Night of the Clan Massacre" is merely the perfect sacrifice for my ascension to the throne!

Konoha? Too small. The ninja world? Just the beginning.

The rules of the ninja world must be rewritten. I will take control of life and death in the name of the Uchiha and amass billions of soldiers.

From this day forward, I will stand at the top.

"Uchiha Madara, do you want to bring peace to the ninja world?"

"Garp, I want..."

"Sesshomaru..."

The worlds are in complete chaos.
