Crowned King, and America Wants to Invade from the Start?

Xia Long transmigrates to a parallel world and binds himself to the Super Military Factory System.

Daxia covers 500,000 square kilometers and has a population of about 50 million.

Xia Long is the king of this country!

No sooner has he taken office than Eagle Sauce wants to invade.

Big Bear: "Brother, your tech is really effective. It cuts through the enemy like a hot knife through butter. From now on, I'm with you. Just point me at the target, and I'll hit it."

Second Bear: "Eagle Sauce, what kind of junk did you send me? Do you really think our weapons are even in the same league as theirs?"

Xia Long orders: "What is this lousy AK? The entire Daxia army is switching to electromagnetic railguns. Sell the rest of this junk to Eagle Sauce!"

Eagle Sauce: "How are we supposed to catch up? Daxia has snatched up all the talent, and scientists call it a sacred ground for research!"

The Three-Body aliens: "Earth's life-forms are terrifying."

The story focuses on technological supremacy.
