Honkai: I Became Kevin's System

Ling was brought to the world of Honkai by a System. At first, he thought he could swagger around the world of Honkai like the protagonists of other novels. But then he discovered that his System had died during the transmigration.

The good news: the System was gone, but you were still alive. The Host was still white-haired and blue-eyed, clearly a top-tier presence on the Honkai power rankings.

The bad news: you were the System.

Ling: "Hello, it's my first time being a System. Any beginner's guides?"

Looking at the Kevin before him, whose clear-eyed innocence was just like a college student's, Ling wondered how he could raise this Flame-Chaser, the Savior, into a proper hero.
