Cohabitation System: Pick up a Cute Noble Lady at the Beginning

System flow + daily love + fighting + traveling through thousands of realms + a world of high martial arts + maybe multiple female protagonists? Three years after traveling through time, Lu Qing suddenly discovered that the world was filled with all kinds of "urban protagonists" - dragon kings, miracle doctors, military kings, and stock gods emerge in endlessly. Just when he thought that was all, a noble girl with silver hair and purple eyes appeared on his bed out of thin air. "I am Arya von Crawford, whose territory is this?" With the arrival of the cute girl from another world, Lu Qing activated the "strongest cohabitation system" - every time he lives with a special person, he can get daily rewards from the corresponding system. But he soon discovered that Arya was not as innocent as she appeared: She claimed to be "not even a magic apprentice", but she actually had terrifying magic power sealed in her body that could tear apart space. When various "protagonists" in the city begin to notice this unusual pairing, when the seal on Arya gradually loosens, and when more travelers from other worlds appear one after another - Gu Qing must use the system's abilities to protect this girl from another world who gradually walks into his heart in this special world where heroes come together. "No matter what is sealed in your body, no matter how many people want to hurt you..." Gu Qing tucked the sleeping Aliya into bed, "I will make this world a place that can protect you."
