Backed by a Level Nine Civilization, Is It Really So Strange for Mecha to Slay Gods?

[Mecha + Cutting-Edge Technology + Unknown Civilization + A Powerful Nation Through Technology + The Stars and Beyond]

Earth has been completely overrun by sea beasts. Reborn, Yu Xingzhou uses the "Level Nine Civilization System" to advance Earth's civilization from Level 0.75 to Level 2 in just a few months.

From then on, mecha technology rapidly evolves. First-generation mecha, second-generation mecha, Primordial-class mecha, Calamity-class mecha: all appear out of thin air!

Controlled nuclear fusion, hand-built mecha, antimatter cannons, space elevators, the Heavenly Palace construction project: none of it is out of reach!

"Humanoid sea beasts? Sorry, humanity has long since achieved biological fusion. What kind of trash are silicon-based lifeforms?"

"Sea beasts, I'm standing right in front of you. Tell me, how much do I look like the person I used to be?"

After the sea beasts are completely wiped out, Yu Xingzhou leads all of Chinese civilization into the interstellar age.

An unknown civilization observes from somewhere in the universe as the "insects" it had sent are wiped out by humanity. Following the Dark Forest theory, it immediately decides to destroy Earth itself.

However, when its first starship reaches the edge of the Solar System, a massive stellar-class mecha appears in the dark void:

"Insolent fools! I am the supreme commander of Huaxia. No one may enter this frontier without Huaxia's dimensional-folding authorization!"

The unknown civilization is horrified: "Initiate spatial jump! Full-speed retreat!"

The next second, a thin "sheet of paper" launches from the Solar System and flies toward their star system.

The unknown civilization: "What?! Is that a Two-Dimensional Foil?"

Yu Xingzhou: "What's a Two-Dimensional Foil? We Huaxia call it the Star-Destroying Book of Life and Death."

"I've got a Level Nine civilization backing me up. It's only natural that my mecha can slay gods, right?"
