In the wasteland of the galaxy, Yun Jibai is an exiled Stardust prisoner, branded with forbidden codes, and makes a living by hunting mechas; Qi Guchen is the most cold-blooded successor to the throne of the empire, holding a star-burning crossbow, and is ordered to hunt him down. When the stardust storm tears apart the throne, the two are forced to coexist on a broken battleship. Yun Jibai's blood can activate the ancient star core, but Qi Guchen's nerve chain can suppress its rampage - they are not allies, but each other's shackles, and the only way to survive. Under the throne, no one dared to believe that a prisoner and a god could ignite the fire of the galaxy together.
