The Cannon Fodder Turns His Sister Into A Soaring Phoenix

When I opened my eyes, I realized I had been reincarnated into a cultivation game. But not as some heaven-defying protagonist, nor even a notable side character. No, I became a nameless NPC with tr*sh-tier spirit roots—doomed to die at the age of fifteen at the hands of a minor villain.
My name is Ye Anping. And yes, I was despairing.
Fortunately, it wasn’t all hopeless.
At least… I was only four years old.
Even better, I had a junior sister—an ordinary NPC according to the game lore—who was actually blessed with peerless talent. A natural genius who could make the heavens weep.
Ten years passed in the blink of an eye.
My junior sister grew up. She became strong. Beautiful. Radiant, like the moon hanging high above the mortal world.
And then, the protagonist noticed her.
And then… my junior sister push me down to the bed!?
Ye Anping: “Junior Sister, I’m your senior brother, I—!”
(Spoiler: it didn’t matter.)
