Lin Xin, a former Earth traveler and a top-100 player in the popular online virtual game "Star Trails," was unexpectedly transformed into an NPC with a player template, resembling her beloved character from her past life, the popular Mijia mobile game, Liuying. Furthermore, she gained a rare golden attribute template and the unique skill "Hero's Heart," which allows her to fuse any object for incredible enhancements. When she integrated the "Hero's Heart" into the damaged Firefly IV Armor Summoner, a series of knight transformation items from the world of special effects appeared: Ace, Fang Memory, Dangerous Rabbit Tank, War God Blade, Kamen Rider Chronicles cartridge, and more.

However, Lin Xin discovered that she not only inherited Liuying's appearance and abilities, but also her terminal illness—an incurable genetic disease called atrophy. To survive, she decided to exploit the rules of the Star Trails AI: becoming a highly popular NPC would grant special treatment, preventing them from being easily "killed."

So in the cutscene CG of the alien beasts attacking the city in the 2.0 version of "Star Trails", players witnessed this scene in shock: a pale, staggering silver-haired girl faced the surging group of alien beasts alone. Behind her was the city of Isuta, which had most of the assets of countless players. The wounds and cracks caused by entropy disease spread to her beautiful face, but the silver-haired girl's eyes were firm. She trembled and slowly took out a blue energy bottle and inserted it into the ice-blue mechanical glove on her left hand.

"Burn the fire in your heart and crush your body..."

"Fireflies fly towards fire, living towards death!"

At this moment, she became the white moonlight in the hearts of countless players...!
