Cui Heng transmigrated into a high-level Xianxia world, according to his system. Immortal Kings roam, ferocious beasts are everywhere, and powerful beings can destroy galaxies and worlds on a whim, terrifying him. Luckily, the system provided him with a three-hundred-year newbie protection period; as long as he stays within the protected area, he won't be harmed. Thus, Cui Heng began his three-hundred-year cultivation journey. During these three hundred years, people strayed into this place. Some were of humble origins, having been monks and beggars, yet harbored ambitions to pacify the world and save the people. Some were of noble birth, once unparalleled geniuses, but suffered misfortunes, their aptitudes plummeted, and they endured scorn. Some were princesses who only wanted to find their brothers, not for immortality, but to reunite. The story follows their interwoven paths.
