Sign-In for a Star-Destroying Battleship from the Start: I Livestream as Its Captain

From the start, he transmigrates into a desolate universe, onto an uninhabited planet, no less!

Luckily, though, he gets a sign-in System and receives a star destroyer ** on his first day!

But upgrading the battleship requires livestream popularity? What the hell? Why not just call yourself a livestream System?

"I'm the captain of a damn star destroyer ** and a space mercenary. Level-one and level-two civilizations tremble at my name, and even level-three civilizations treat me with respect. And now a resident of a level-zero-point-something civilization is mocking me on a livestream???"
