Rabbits Are Weak? I Pay to Upgrade to a Level Three Civilization!

Ye Feng transmigrates to a parallel world, becomes a graduate of a national defense university, and awakens a Tech-for-Cash System. As long as he spends money, he can obtain blueprints for technologies from civilization levels one through four.

In this world, Longguo is under a technological blockade, and every field of technology is stuck decades in the past!

First, he builds a missile interception system to keep Longguo safe!

Then he builds nuclear weapons, forging a sword for Longguo!

Next, he builds space-based satellites to survey the world from orbit!

After that, he upgrades the army, navy, and air force, develops the Nantianmen Project to race across the cosmos, and advances to a higher civilization!

Uncle Sam: "We kept the rabbits' technology locked down for a hundred years. How did they get into space?!"

The Bear: "Longguo, we've always been friends! Please take back that nuclear-powered tank!"

Kimchi: "You won't believe this, but our White Tiger Regiment vanished as soon as it reached the battlefield!"

Cherry Blossoms: "Do we still have a chance?"

Camels: "Friends in Longguo, we understand technology!"

Just as the world thinks Longguo is merely rising as a technological power,

Ye Feng has already built the Luan Bird and set off for the cosmos!
