In the boundless universe, the swordsman Mu Yang witnessed the destruction of a planet with his own eyes. In the desperate destruction, Mu Yang saw a faint light of fireflies...
That was a Grammer Cavalry, the last Grammer Cavalry in the world...
Her name is Liu Ying, and she gained a new life in the midst of destruction...
Mu Yang met the dying Liu Ying in a distant planetary belt and brought him back to his own planet, the Nameless Star.
There is no one on this planet, only Mu Yang lives here. With the arrival of Liuying, a touch of firefly light has been added to this nameless planet.
Until one day, a star core that became the cancer of all worlds suddenly descended on this planet and brought a devastating blow to it...
The peaceful and peaceful planet has turned into a devastated ruin...
A train with dazzling brilliance passed by this planet and stopped its progress. A Herrscher of Reason, a reincarnated Dragon Lord, a star core carrier, an amnesia girl, a train navigator...
They call themselves pioneers and come to solve the star core crisis...
At that moment, under the stars in the sky, he became her patron saint...
