The Ultimate Braggart

I have a System that lets me show off, transmigrate, and gain all kinds of skills:

At the whole-school assembly, the principal singles me out for criticism. I point at something, and it falls, smashing into the principal's head;

The campus belle is always picking fights with me. How do I win her over?

The System creates an app for "Poop Space" and "Piss Way." Now things get interesting. The Japanese are dumping nuclear wastewater everywhere, so I use S to build an island and fence off the polluted waters. The ocean currents will carry them back to Japan. If they still won't learn, I'll livestream "Sky Turds Over Tokyo" to the whole world;

It turns out that aliens are behind Ling Yunfei's transmigration. The alien Yixiu's home planet was destroyed, and he sent Ling Yunfei across worlds to protect Earth.

After transmigrating, Ling Yunfei builds a nation, expands its territory, and unifies the Earth. His ultimate goal is to protect the planet and fight the aliens.

Ling Yunfei obtains the only show-off System in the entire universe:

Master: Ling Yunfei

Level: Lv1

Blessing: 0.1 yuan per second of showing off

Show-Off Points: 50/10000

Transmigration Skill: 0 seconds

The System is online, and the show-off life begins! Protecting Earth is everyone's duty.
