After Rebirth, I Led the Country to Conquer All Realms

Lin Xiaoxiao, an unlucky guy who has been living in the world of immortality for thousands of years and became a top student in the interstellar era, opened his eyes and returned to the senior high school classroom. When she opened her eyes again, she was back in the classroom before the college entrance examination! Before she could rejoice, a cute new system came to her door crying: [Host, I'm sorry! In the past two lives, you were thrown into the world of immortality to survive and become a master of interstellar scrolls. It was my mistake in sending you the wrong copy! Please don't complain! After a thousand years of wandering in the world of immortality and the interstellar era, Lin Xiaoxiao was reborn and returned to the high school classroom. Faced with the compensation from the Mengxin system - [Permission to travel across all realms], she did not hesitate. On the day of handing in the college entrance examination, she walked directly into the door of the National Security Bureau. "I want to see your top person in charge. I can take you to other worlds to build infrastructure." The next day, the cold and steady young officer Gu Yan was ordered to come and become her exclusive guardian. While other countries were still complacent about a technological blockade, Dragon Kingdom's "Pangu Plan" had quietly launched: Immortal Cultivator World: "Friend Qingyun Sect, this solar lamp is brighter than the night pearl. Can we cooperate in building the power grid?" ... In the interstellar ruins, our archaeological team recovers lost technology; Even before traveling to the west to measure the calamity, "quietly collect some 'law samples' and don't disturb the Bodhisattva's mount!" We can also contribute to the order of heaven and earth... Gu Yan was always by her side, from looking at her to admiring her, to showing her irreplaceable affection. And that little talkative system Xiao Wan's biggest hobby is to be "jealous" with Gu Yan: [Host! Did he bring you breakfast? Watch me sign in and give you a spiritual chef feast! Lin Xiaoxiao: Don't make trouble, you are all my wings. "Xiaoxiao, you are responsible for lighting up civilization, and I am responsible for protecting you."
